In a groundbreaking development for the construction industry, the utilization of cage welding machines has transformed the production of spun piles and concrete poles. These machines have streamlined and automated the manufacturing process, resulting in increased efficiency, improved quality, and reduced labor costs.   Traditionally, the construction of spun piles and concrete poles involved time-consuming and labor-intensive manual labor. Workers had to manually bend and weld individual steel bars to create the cage structure, a process that was not only time-consuming but also prone to human errors. However, the advent of cage welding machines has brought about a paradigm shift in this aspect of construction.   Cage welding machines are capable of bending and welding steel bars at a rapid pace, ensuring uniformity and precision in the production process. These machines incorporate advanced technology and computerized controls to automate the entire manufacturing process. The steel bars are fed into the machine, which then cuts, bends, and welds them to form the desired cage structure. This automation significantly reduces the need for manual labor, resulting in increased productivity and cost savings.   The application of cage welding machines in spun pile and concrete pole production has also led to improved quality. The precision and accuracy of these machines ensure that each cage structure is consistent in its dimensions and meets the required engineering specifications. This uniformity in construction leads to stronger and more durable spun piles and concrete poles, enhancing their longevity and performance.   Furthermore, cage welding machines offer versatility in design options. They can produce cages of various shapes and sizes, accommodating different project requirements. This flexibility allows construction companies to cater to the specific needs of their clients and adapt to various construction applications.   The adoption of cage welding machines has revolutionized the construction industry, making the production of spun piles and concrete poles faster, more efficient, and of higher quality. This technological advancement has not only improved the construction process but has also opened up new possibilities for innovative and sustainable infrastructure development. As construction companies continue to embrace this technology, we can expect to witness further advancements that will shape the future of the construction industry.

A concrete steel pole pipe pile mould is a specialized mold used in the construction of concrete steel pole pipe piles. These molds are typically made of high-quality steel and are designed to create a specific shape and size for the pile. The mold is filled with concrete and steel reinforcement, and then the pile is left to cure and harden before it is removed from the mold. These molds are essential for creating strong and durable steel pole pipe piles that can be used in various construction projects.A concrete pipe mould is a tool used in the manufacturing of concrete pipes. It is typically made of steel and is designed to shape and form the concrete into the desired pipe shape. The mould is filled with wet concrete, which is then allowed to cure and harden before being removed from the mould. This process results in a strong and durable concrete pipe that can be used for a variety of applications, such as drainage systems, sewage systems, and culverts. Concrete pipe moulds come in various sizes and shapes to accommodate different pipe diameters and lengths.

The assembly process of pile mold is mainly divided into three major parts: disassembling mold, preparation before using the mold and assembling the mold respectively. I. Disassemble the mold (referred to as disassemble the mold) When the pile and the pile mold complete the atmospheric pressure curing, and the concrete strength reaches the demoulding strength (45MPa), the mold can be disassembled, so that the pipe pile mold and the tensioning device can enter into the next production cycle as soon as possible to improve the utilization rate of the pipe pile mold. The disassembled pile will be sent to autoclave for high pressure steam maintenance. Preparation before using the mold Pile molds are used repeatedly in the production cycle. When the molds are used in the previous production cycle and the piles are disassembled, the molds will be lifted back to the assembling area to prepare for the next production cycle. The molds need to be prepared before the skeleton is installed so that the molds meet the requirements to enter production again. The preparation consists of 3 steps: mold cleaning, spraying release agent and checking the clamping bolts. Pile mold cleaning work, mainly clean the inner wall of the steel mold and the mouth of the enterprise residual debris, to ensure that the steel mold before going into production to meet the clean requirements. The inner wall should be clean and free of debris, no rust stains, no grooves, cracks, etc., to avoid the appearance of pipe pile quality problems. Spraying release agent is arranged after the mold cleaning, spraying release agent evenly and fully on the inner wall of the upper and lower semi-circular molds of the pipe pile molds, to ensure the formation of a complete, continuous and even thickness of release coating in the inner wall, to avoid the concrete sticking to the mold during the hydration reaction, and to facilitate the smooth separation of the pipe pile from the mold during the demolding process. When checking the clamping bolts, make sure that the clamping bolts bolted on the mold are intact and can work normally. The clamping bolts should ensure that the upper and lower molds are closed firmly and can withstand the lifting and high-speed centrifugation of the molds without loosening. Pile mold assembly When the pile mold is ready and the steel skeleton is finished, it will enter the mold assembly process: the steel skeleton will be assembled with the pipe pile mold and tensioning device. The work of mold assembly is mainly to suspend the steel skeleton in the lower half-circle of the mold, install the tension baffle and head-tail plate of the mold in the end plates of both ends of the skeleton, and fasten the tension screws of the head-tail plate, so as to make the skeleton and the mold fixed as a whole. Some of the pile enterprises adopt the improved process of clamping fabric such as pumping or screw feeding, at this time, the mold installation also needs to close the upper semi-circular mold to the lower semi-circular mold in advance, and tighten all the clamping bolts on both sides, which is also known as clamping the mold in advance, which is included in the assembly process.

A concrete pile cage welding machine is a specialized piece of equipment used in the construction industry to manufacture reinforced concrete piles. These piles are used to support structures such as buildings, bridges, and highways. The machine consists of a cage welding system that automatically forms and welds the steel reinforcement cages used in concrete piles. It typically includes a series of wire straightening and cutting machines, a cage forming machine, and a welding machine. The process starts with the wire straightening and cutting machines, which straighten and cut the steel wire into the required lengths. The cage forming machine then bends and shapes the steel wire into the desired cage configuration, which is typically cylindrical. Once the cage is formed, it is transferred to the welding machine, where the individual wires are welded together to create a solid and strong cage structure. The welding machine uses a combination of resistance welding and fusion welding techniques to ensure a secure and durable weld. The finished cage is then ready for further processing, such as coating or galvanizing, before being used in the construction of concrete piles. The machine is designed to be fast, efficient, and accurate, ensuring consistent and high-quality production of concrete pile cages. Overall, a concrete pile cage welding machine is an essential tool in the construction industry, enabling the efficient and cost-effective production of reinforced concrete piles.

The production method of prestressed concrete square pile steel skeleton roller welding machine Prestressed concrete pile is a kind of prestressed concrete prefabricated parts made by using pretensioning process and centrifugal forming method through steam curing, which has the advantages of strong single pile bearing capacity, large friction coefficient, low cost, easy to use and convenient for standardization, etc., and has been paid more and more attention by people. In the past, China in the manufacture of prestressed concrete pile reinforcement skeleton, most of the production method using manual tying or welding, so that not only labor intensity, low production efficiency, and the quality of the product can not be guaranteed, since the reform and opening up, especially in recent years, with the port, bridge, high-rise building business booming development, the demand for prestressed reinforced concrete pile gradually increased, the quality of the pile According to the market needs, in the early years, our factory had researched and developed one of the main equipment for prestressed concrete piles-prestressed concrete pipe pile steel skeleton roller welding machine, and obtained the patent of microcomputer-controlled cage welding machine for reinforced concrete piles, pipes and rods. The object of use of the patent is cylindrical prestressed concrete pipe piles. The prestressed concrete square pile reinforcement skeleton differs from the round cross section of the prestressed concrete pipe pile reinforcement skeleton due to its square cross section and the unequal distance of its centre point to the periphery. Therefore, the prestressed concrete square pile welding machine is difficult to achieve mechanised automatic welding production. Prior to the publication of this patent application, the production of prestressed concrete square pile steel skeleton in China can only be produced by hand-tying or by manual welding, which is not only labour-intensive and inefficient, but also cannot guarantee the quality. Due to the high quality requirements of buildings for prestressed concrete square piles, hand-tied or hand-welded prestressed concrete square pile steel skeletons not only cannot meet the needs of construction development in terms of quantity, but more importantly, the quality cannot meet the engineering specifications, thus hindering the development of prestressed concrete square piles for a long time. The research and development of one of the main equipment of pre-stressed concrete square pile - pre-stressed concrete square pile steel skeleton roller welding machine, will play a positive role in the development of pile cage welding machine.

In order to strictly control the quality of the products, it is necessary to strengthen the control of the four key processes of mixing, tensioning, centrifugation and maintenance in order to meet the requirements of customers and improve the internal management level. I. Concrete Mixing Process The square pile concrete mixing process (process) is the key process (process) in the square pile production process - the quality control point. How to implement this quality control point correctly and ensure that the quality of this key process is under control should start from the following points. 1. Stability of the weighing system (1) Weighing system. It is mainly composed of weighing platform frame, weighing hopper, sensor, display instrument, connection line (signal cable) and so on. The stability and precision of the weighing system directly affects the manufacturing quality of concrete. (2) the rigidity of the scale platform reliability. Most of the scale pedestal (seat) are made on the floor frame of the mixing building installed, or with a crane scale, or with a cantilever scale. Therefore support the sensor scale platform frame must be solid, good rigidity, weighing after the scale stand (seat) will not be deformed, shaking, the mixing floor frame should also have sufficient rigidity to avoid the scale platform frame shaking deformation when the mixer is running. (3) The freedom of the weighing hopper. Weighing hopper as a concrete raw material ratio of the storage container, in weighing measurement must be fully flexible and free, in addition to the sensor pivot point, it can not be affected by the interference of other connections, otherwise it will affect the accuracy of weighing. To keep the weight of the weighing hopper and the surrounding frame clearance ≥ 2cm, each weighing hopper inlet, outlet should use soft connection, cement, mineral powder using filter cloth to do soft connection, in order to play the role of exhaust. Water scales, admixture scales are used soft PVC double-sided glue tape, both soft connection and impermeable. Do not pull too tightly when fixing the soft connection, to ensure that the scale bucket has a certain amount of wobble. Water scales, admixture scales should be additionally fixed at the input of the pipe, not directly resting on the scale bucket, the pipe outlet installed pneumatic butterfly valve, so as not to affect the accuracy of weighing. (4) the selection and installation of sensors. Sensor weighing range should generally be weighed and the total weight of the weighing hopper 3 to 5 times appropriate, both to consider the impact of weighing materials, but also to consider the value of too large when the accuracy is reduced. The structure of the sensor form hanging (hanging) and cantilever two, hanging suitable for weighing small cases, such as water scales, admixture scales, cantilever suitable for stone scales, sand scales, cement scales, admixture scales, etc.. However, in many mixing plants there is also a large number of ground weighing systems using suspended sensors, which are suspended directly under the storage bin, together with the horizontal belt weighing or a separate weighing hopper scale before being placed into the horizontal belt. The cantilevered sensor should be installed according to the direction of the arrow indicated by the sensor and should not be installed in the opposite direction. After weighing should also pay attention to the sensor cantilever end of the bottom surface and fixed bracket whether there is more than 5mm gap, use should also be frequently checked whether the gap part is cement lumps, other debris, sand and other debris blocked and affect the weighing accuracy. In addition in the installation or maintenance of the weighing system, the sensor can not be used as a welding connection conductor, arbitrary fire, welding in the high current will inevitably cause sensor failure distortion. In the production process, the weighing system should also be frequently checked, maintenance, regular calibration of the scale. 2. advanced, reliable and stable control system (1) the composition of the control system mainly includes the electrical control system, microcomputer control system and television monitoring system. There are two types of control systems that can be used to produce concrete independently: one is manual, i.e. the production of concrete is completed by manually operating the relevant buttons with the aid of the industrial control machine; the other is automatic, i.e. the automatic production and management of concrete is achieved entirely by the industrial control machine. The two control methods can be interchanged by means of a changeover switch. (2) The electrical control system consists of two parts: the electrical cabinet and the operating console. The electrical components shall be of high quality and reliable products, and the quality of the products shall conform to the relevant international (IEC-947) standards and regulations. The electrical components in the electrical cabinet are installed with standard card tracks and wired in front of the board, which brings great convenience to maintenance and installation. The system has two operating consoles (or operating areas): the large console mainly controls and monitors the production of the mixing equipment, while the small console is used to control and monitor the loading of the aggregate bin divider and various aggregates, and the loading control of the powder bin. The buttons of the two operating consoles are arranged in accordance with the production process and are marked in Chinese to make the operation clearer and easier for the operator to grasp and use. The input power supply to the control system should be stable and it is recommended that a voltage regulator be installed. Due to the large dust in the mixing building, the components should be blown and dusted regularly to prevent the accumulation of dust from causing short-circuit tripping, deadlock, misoperation and burning of components. (3) The microcomputer control system adopts the MK2000 square pile production management system software, which is mainly composed of two functional modules: automatic production control system and production management system, and is powerful. The automatic production control system uses standard IPC industrial control machine to measure, display and control the control signals of the concrete mixing plant production system in real time through industrial standard sensors, hardware circuits and I/O interface boards, with functions such as ratio storage, automatic compensation of dropout, compensation of moisture content of sand and gravel, etc. It can also accurately and conveniently input, call out and modify the set values and formula numbers of each material. It can also make hints for errors in the production process and realise the automation of concrete production. The production management system is controlled by a computer network, which enables comprehensive networking of the dispatching office, test room, control room, transport department, general manager's office and other business departments. It provides comprehensive digital management of important production data such as production task orders, construction ratios, raw material intake and consumption, commercial concrete production and delivery records (concrete mini-ticket records) and various production reports, which greatly facilitates the management and decision-making of the enterprise and improves its competitiveness. This greatly facilitates management and decision-making and improves the competitiveness of the enterprise. The system has perfect self-locking and interlocking functions to ensure accurate and reliable operation, as well as common fault detection and alarm functions. (4) The TV monitoring system is mainly composed of colour cameras, auto iris lenses, colour multi-screen processors and colour industrial monitors. External production can be easily observed through TV monitoring in order to prevent unexpected situations. The system has several sets of proportioning libraries, which can meet the needs of the technical department in many ways, such as construction proportioning and theoretical proportioning. All technical reports are automatically generated and can be printed at once, and various reports can be adjusted by the user like WORD. The technical department receives information on production tasks through the network, from the matching ratios to the factory information, both in terms of working time and workload, which is a qualitative leap forward from before the use of the system. (5) At present, many enterprises in the statistics of the number of raw materials consumed, still use the production ratio of a single party consumption multiplied by the amount of production to calculate the overall amount of raw materials for each raw material, but the proportion of materials used and the actual consumption of materials (material scale) is a certain error. The system automatically collects and transfers the amount of material consumed for each tray of concrete produced, compares the design and actual amounts, displays both amounts of material consumed and the error rate, and records in detail the time, volume, feed truck number and pile type and specification of each tray of concrete produced, providing an accurate and secure basis for multiple management analyses such as concrete quality tracking, batching system bin calibration and actual consumption of raw materials. 3. the design of the mixer's internal mixing function 3. The mixer's internal mixing function is well designed and uniform There are two types of mixers: vertical shaft planetary mixers and double horizontal shaft forced mixers. These two types of mixers have their own characteristics and are widely used. (1) vertical shaft planetary mixer mixing principle for the public rotation plus rotation, there is a complex mixing curve, can be completed in a very short period of time mixing work, is a complete forced mixer, with long-term dry mixing capacity. Compared with the horizontal shaft mixer, it has the characteristics of no shaft end seal and no slurry leakage; compared with the vertical shaft mixer, it has the advantages of small motor power, no material jamming and small wear-resistant parts. (2) double horizontal shaft forced mixer mixing shaft using a new shaft-end conical spiral bevel gear - planetary gear reducer drive, horizontal cylinder body installed with a double shaft rotating reverse paddle, paddle into a certain angle of the material to the axial, radial tumbling, so that the material quickly and evenly mixed. It is also a compulsory mixer, the intense mixing movement shortens the time of one mixing, more rapid and efficient. As the transmission gearbox outside the cavity, maintenance maintenance is easier. (3) Mixing is the use of mixing leaves of the compulsory force, the gravity of the material, so that a variety of materials such as coarse aggregate, fine aggregate, powdered cementitious materials, water, water reducing agent, etc. evenly mixed together to form a gel-like flowable concrete process. The mixing process is divided into two stages, the first stage is dry mixing, generally 5 to 30s, this stage has a great impact on the homogeneity of the concrete mix; the latter stage is wet mixing, generally controlled between 70 to 120s, all the materials will be mixed together, so that it becomes a new gelatinous concrete material. If the mixing is not homogeneous, the concrete will segregate, then the strength will be higher for more coarse materials and relatively lower for more fine materials. Therefore, the design angle of the mixing blade, blade size should be suitable for the production requirements of pipe pile concrete, in addition to the raw material feeding procedure should also be reasonably designed. (4) The material feeding sequence and the water consumption of concrete (water-cement ratio) control plays a very critical role in the concrete's compatibility and flowability. At present, there are the following feeding methods: ① a feeding method, the cement, admixture, sand, stone, a one-time input, dry mix and then throw water wet mix, and finally add water-reducing agent mixing; ② sequential feeding method, according to a certain order, such as sand, cement, admixture, gravel sequential feeding, first dry mix, then add water wet mix, and finally add water-reducing agent mixing; ③ mixed feeding method, first into a part of the same material, and then successively Input, such as sand, cement, admixture, dry mixing, and then cast most or all of the water, wet mixing for a short time, and then cast the gravel to continue mixing, plus the remaining water and then mixing. Water reducing agents are weighed more evenly if they are added to the water together. The mixing process for square pile concrete is preferable to the mixed feeding method, which makes full use of the effective time and is balanced according to the characteristics of the material. In the sand and gravel under the material on the side of the open mixing, under the sand and gravel and then under the cement and admixtures, dry mixing time to be short, add 60% water and water reducer wet mix, and finally add the remaining 40% water mixing. Of course, square pile manufacturers can also aggregate, powder, the specific feeding order combined with the actual adjustment, test, both to make the cementitious materials to improve the strength of the role, but also to take into account the performance characteristics of the mixer itself equipment. Reasonable feeding order to improve the strength of concrete, reduce the amount of cement is of great help. Second, the prestressing tensioning process The role of prestressing is mainly: to apply precompressive stress to the steel reinforcement in the tensioned square pile before the pile is subjected to load, to improve the stiffness and flexural properties of the member, to delay the appearance of cracks and to increase the durability of the member. Therefore, in order to ensure the safety and reliability of the square piles in terms of demoulding and lifting, loading into the cauldron, storage and stacking, shipping and loading, site unloading, pile construction, pile bearing and durability, it is necessary to identify the prestressing tensioning process (process) as a key process (process) and quality control point of the quality system. The prestressing reinforcement is tensioned after the concrete is placed and moulded, before centrifugal forming and steaming. The prestressing tensioning process is carried out in a single step on the outside of the mould, with both central tensioning and external tensioning, generally for large diameter square piles above 800. The tensioning process is controlled by both the prestressing force (shown by the oil pressure gauge) and the elongation value, with the oil pressure being the main control and the elongation value being the secondary control, both data being recorded for inspection. 1. Calibration of the tensioning machine The calibration of the prestressing tensioning jack is a very critical part of the prestressing structure project. The accuracy of its calibration will directly affect the prestressing value and the performance of the pile on which it is built, especially in the construction of square pile elements with small prestressing values. In addition, the oil pressure gauge should also be calibrated at the same time. The above calibration work should be carried out regularly by the local metrology department and an inspection report should be issued. 2. Tensioning tooling components (five sets) of processing, assembly accuracy, tensioning specifications Tensioning tooling components (tensioning device) generally have tensioning screw, tensioning nut, anchor plate, fixed plate, tensioning plate five pieces, also called tensioning five pieces set. The concentricity of the tensioning plate, the fixing plate and the end plate of the square pile, their concentricity, the accuracy of the outer circle size and the clearance of the inner hole of the steel mould determine whether there is a loss of prestress during tensioning, similarly, the concentricity of the tensioning screw and the inner hole of the anchor plate, the small clearance and friction will also lead to a loss of prestress. After tensioning, the pressure should be maintained for 10-20s, and the tensioning nut or ring should be quickly locked with plates, pawls and other tools to minimise the loss of prestress. In old square pile plants that have been in operation for several years, tensioning often uses parts such as pad screws, sleeves and spacers due to damage to the fillet teeth of the tensioning screw, which should be avoided as far as possible because it is not easy to lock the large tensioning nut. 3. Cleaning and lubrication of the die Generally in the tensioning plate, fixed plate assembly corresponding to the position of the steel die cylinder inner circle surface to brush waste machine oil, if there is residual concrete, cement paste must be cleaned up, so that tensioning friction resistance is small, less prestress loss. After feeding and before closing the mould, it must also be checked that no concrete debris has fallen into this position and must be cleaned before tensioning. 4. Ring reinforcement The cage is automatically spot welded by a roll welder, if the welding is not secure, or if the cage falls apart during assembly and feeding, the ring reinforcement falls down and the outer diameter of the cage becomes smaller, the prestressing bars will not be in a straight line during prestressing tensioning and the prestressing force will decompose a force in the vertical direction, resulting in a partial loss of prestressing force. In summary, there are a variety of prestress losses in the prestressing tensioning process. Therefore, although the process regulations require the prestressing value to be 70% of the tensile strength of the standard prestressing reinforcement, in practice the loss of prestressing should be considered and the oil pressure gauge value should be controlled between 70% and 75%, taking the upper limit as appropriate, especially for long piles. III. Centrifugal forming process Centrifugal forming is the process of using the centrifugal force of the rotating material to orderly arrange the swimming concrete in the steel mould to form a dense concrete layer (process). The denser the concrete, the higher the strength and vice versa. The design of the centrifugal process system directly determines the strength of the concrete and the quality of the appearance of the pile. 1. The precision of the operation of the centrifuge and the steel mould (1) The level and parallelism of the centrifuge must be regularly corrected, the foot screws and connection screws are tight and not loose, there is no vibration when the centrifuge is running, the spacing of the centrifuge pallets is accurate and not slippery, and the transmission belt is tight and not slippery. (2) Good concentricity of the steel mould, consistent wear of the running wheel, good straightness and no deformation, no misalignment with the steel mould running wheel, no jumping of the tube mould during centrifugation. (3) Periodically use the tachometer to check whether the rotational speed of the steel mould is consistent with the set centrifugal process speed. 2. Determination of the centrifugal process system (1) Choice of centrifugal speed: The centrifugal speed determines the size of the centrifugal force. Under certain conditions of collapse, it is crucial to choose the best centrifugal speed. The centrifugal process is generally divided into four stages: low speed, low to medium speed, medium speed and high speed. The low speed stage, also known as the fabric speed stage, is designed to make the concrete in the mould evenly distributed along the longitudinal direction of the mould and to have a partial mixing effect. Medium speed, low medium speed for the transition speed stage, play a uniform, mixing, speed conversion role, so that the concrete forming a gradual and continuous process; high-speed stage for the concrete dense speed stage, it increases the centrifugal force, so that the concrete mix fully dense, precipitation slurry water. (2) Selection of centrifugal time: According to the actual situation of the concrete mix and the running condition of the equipment and steel mould, the centrifugal time of the four stages should be reasonably selected. The low speed time should not be too short and too long, too short then the concrete adjustment is not uniform, too long will intensify the friction between the inner wall of the steel mould and the concrete, destroying the isolation effect, thus leading to the outer wall of the square pile sticky skin, pockmarked, spalling, difficult to take off the mould. The total centrifugation time is controlled within 9-15min to improve the efficiency of the centrifuge and to save electricity. The four stages of centrifugation time is about 2~4min for slow speed, 1~2min for low to medium speed, 1~2min for medium speed and 4~8min for high speed, for reference only. Fourth, the maintenance process Maintenance also has a great impact on the strength of the concrete, maintenance is not in place, the concrete will produce dry shrinkage cracks, the strength of the concrete is greatly affected. For the production of PC pile products, atmospheric steam curing should be the key process (process), and for the production of PHC pile products, pressure steam curing should be the key process (process). 1. Normal Pressure Maintenance Atmospheric curing is the steam curing of steel moulds and square piles together in a steam curing pond to bring the concrete strength of the square piles to the demoulding and tensioning strength, and to ensure that the strength of the PC square piles meets the requirements (e.g. C60, C70 strength grade, etc.). The normal pressure curing is divided into four stages: static stop, temperature rise, constant temperature and temperature drop. The heating rate is uniform and should not be too fast to prevent damage to the concrete structure. The pool steam pipe is evenly distributed, heating will be uniform, the pool cover insulation, no leakage of steam. The thermometer is regularly calibrated and the maintenance time must be ensured that the pool is not opened in advance in pursuit of production efficiency. The atmospheric pressure curing process system is also determined only through several trial formulations in the laboratory. 2. Pressurised steam curing Press steam curing refers to the process of loading the square piles into the autoclave after demoulding and curing them at high temperature and pressure by saturated steam, which is the process of the concrete strength rapidly reaching the design strength of the product. There are four stages of steam curing: rising pressure, constant pressure, lowering pressure and lowering temperature. This steam curing process can bring the concrete strength of pipe pile to C80 grade or above, which is PHC pile cage welding machine. The pressure boosting stage should be slow and even, with a time control of 1.5-2.5h; the constant pressure stage should ensure that the pressure is 0.9-1.05MPa and the temperature is around 180°C, with a time control of 3.5-4.5h; the pressure lowering stage should also be slow and even, with a time control of 1.5-2.5h; finally, the temperature lowering stage, although the pressure is zero, the temperature of the square pile is still very high, reaching between 80-100°C. The temperature difference between the pile and the outdoor temperature is too large, so it is necessary to avoid the uneven shrinkage of the concrete due to the sudden cooling. In general, the kettle door is slightly open, half open or fully open, and the square pile cage welder factory can make a heat preservation shed or cover with windproof tarpaulin when it cools down to a slightly higher temperature than the kettle or shed, which is especially important in the cold northern region. With regard to the development of the compression and steam curing process system, each pile plant should conduct tests and proofs according to its own concrete mix ratio, demoulding strength, steam quality and the equipment of the steam kettle. Pre-stressed square pile cage welder are all realized through the above four processes, so the key control of the above four quality processes, which affect the key products, is listed as a key process and will surely achieve great results.

Introduction to the knowledge of prestressed square piles Prestressed square pile cage welder are widely used in various projects for their safety and reliability, moderate price, ease of construction, short construction period and other advantages. In the process of using prestressed square piles, attention needs to be paid to quality control and the following quality problems need to be avoided. 1. Fracture of prestressed square pile cage welding machine , which is a common quality problem. However, this type of problem is not easily detected and is usually discovered after the piling is completed. 2. is pile top breaking, pile top concrete breaking during pile driving, mainly caused by improper selection or operation of construction tools, using the correct tools and adopting the correct construction methods, can be avoided. 3. is the displacement of the pile top of prestressed square piles, mainly due to inaccurate pile placement and large deviation, as long as the placement is strictly controlled construction quality. 4. is the pile body tilt is mainly caused by the deviation of the fixed position of the pile driver or the tilt during construction. 5. the quality of the pile and the piling machine problems. Construction quality needs to be controlled in strict accordance with the relevant regulations and design. In conclusion, pile cage welding machine need to be of high quality, only then can the quality of the project be guaranteed. What factors will affect the performance of prestressed square piles? How can their life span be extended? The level of manufacturing process determines the performance of prestressed square piles. Different manufacturers differ in their manufacturing processes, resulting in a wide variation in the quality of equipment and products. Then, through continuous technical accumulation, the manufacturing process can be better and the overall effect can meet the expected requirements, both in terms of load bearing capacity and acid and alkali corrosion resistance, which can have a very good performance. Of course, in addition to the factors of manufacturing process and materials, its performance is also related to daily maintenance. Without better maintenance and care during use, the stability of the product's performance can be greatly reduced. Maintaining the product from multiple angles will give it better performance advantages and is an important prerequisite for production and use, and cannot be chosen blindly. In short, to make the performance of prestressed square piles better, you need to better grasp the selection of materials, and then ensure that the manufacturing process can be better, after ensuring that the daily maintenance in place, which is an important means to extend the life of the product, but also to obtain better quality of the important premise, so you need to carefully compare the choice at any time. After all, you can ensure that the equipment can have better performance, but also consumers to enjoy better quality of the important premise. Transportation of pre-stressed square piles Precast reinforced concrete precast piles should be set aside for a certain period of time so that the strength of the pile is consistent with the design strength. The piles can only be transported and driven in after they have reached the design strength, which also fully ensures the quality of the piles. If the strength is insufficient, they are easily damaged during transportation and the quality of construction is not guaranteed. If lifted in advance, be fully prepared, take appropriate handling measures and only transport after inspection and passing. Pay attention to the lifting and handling of the piles, taking care to avoid vibration and impact. The position of the lifting points should be in accordance with the design requirements and the lifting points should be subjected to simultaneous forces. When there is no lifting ring in the engineering design, according to the actual engineering situation, it is generally determined according to the location and number of tying points, according to the pile length, with a small lifting moment as the principle.

At present, enterprises producing precast concrete piles in China are mainly located in South China, the Yangtze River Delta region, the Bohai Sea region and economically developed regions such as Jiangxi, Henan and Hubei, with Guangdong, Jiangsu and Zhejiang and Shanghai being the most densely populated regions. In terms of regional layout, the enterprises producing precast concrete piles are mainly distributed in the three more developed economic regions of East China, Central China and South China. With the further implementation of the national "One Belt, One Road" initiative, the pace of the precast concrete pile industry "going out" is gradually accelerating, some enterprises and groups have invested in overseas (such as Southeast Asia, etc.) to build precast concrete pile production lines, and with the relevant countries of the enterprise The company is cooperating with enterprises in relevant countries to develop the international market. The export volume of domestic precast pile production equipment has also increased significantly. Cage Pipe Welding Machine are mainly used in construction projects in areas with soft soil geological structure, so pre-stressed concrete pile enterprises in China were first concentrated in the Pearl River Delta region, with the growing market demand for products, product applications continue to expand, and are now widely distributed in the Pearl River Delta region, the Yangtze River Delta, the Bohai Bay region and the major inland lakes (such as Dongting Lake, etc.) region and other provinces, regions and cities, The distribution trajectory of the industry revolves around the coastal and riverine areas. The distribution trajectory of the industry revolves around coastal rivers, lakes and soft land areas. Due to its large size and weight, Concrete Pole welding machine are currently mainly transported by road, which is limited by the economic radius of transportation and can only cover the market within 150 km of the production base. Therefore, in terms of scale and production capacity, most concrete pipe pile enterprises are still concentrated in Guangdong, Jiangsu, Zhejiang and Shanghai and other regions with a developed construction industry. Electrical Pole Cage Welding Machine enterprises with first-mover advantages have occupied a large part of the market at the initial development of the industry, and their advantages in terms of scale, technology, capital and human resources are ahead of latecomer enterprises. The advanced enterprises, by virtue of large-scale production, dilute the unit cost, and the economy of scale effect makes their products form a price advantage in the market. In addition, enterprises with scale advantages in the industry can improve their bargaining power with upstream and downstream enterprises, thus being able to effectively control production costs. The newcomers, due to the small scale of production, are unable to reduce production costs, coupled with a large amount of research and development, equipment investment in the formation of sunk costs, do not have a strong competitive price, in the market competition is very easy to be eliminated. Due to the large volume and quality of prestressed concrete piles, high transportation costs and the existence of product transportation radius, the product sales market is mainly concentrated in the radiation area around each production base. Enterprises wishing to expand their markets need to set up new production bases in the target markets to reduce transportation costs, with large investments in plants and equipment, which are affected by the industry cycle and difficult to obtain profits in the short term, with a long payback period and high capital barriers. The national requirements for environmental protection standards in this industry are getting higher and higher, especially the regional governments have successively increased the implementation of the coal-to-gas policy. At the same time in recent years, the state vigorously advocate energy conservation and emission reduction, optimize production capacity to adjust the industrial structure and other related industrial policies, making some regional governments directly on the precast concrete piles for special rectification action, some small-scale enterprises in the industry or because of environmental protection is not up to standard and not timely rectification, or due to the high cost of equipment renewal and transformation and difficult to continue to operate, and finally in the action around the elimination of backward production capacity directly out of the The market for pipe and pile is being driven by national policies. As a result of these national policies, new barriers to competition were created in the industry, which ultimately led to a further increase in the entry barrier for the industry and a further increase in the market share of the top pipe pile producers in the industry, such as the Company.

Ordinary reinforced concrete pole mould is mainly composed of reinforced concrete and concrete, concrete is an important part of the whole pole, with different kinds of concrete production of the pole its mechanical properties are not the same. Let's briefly analyze the composition and classification of the concrete used in the pole. In the official definition of concrete, it is the general name of engineering composite material which is composed of cementitious material to cement aggregate into a whole. Intuitively speaking, the concrete used in the pole is a mixture of sand, stone, cement, water (mixed with admixtures or mineral mixing materials if necessary) mixed together in a certain proportion, also known as concrete mix. Before the cement paste sets and hardens, the concrete has a certain workability, which is called fresh concrete; After hardening of concrete, it is hardened concrete, commonly known as artificial stone. Sand and stone (also known as coarse aggregate and fine aggregate) are the main components of concrete. As filling materials, they play the role of skeleton support, accounting for more than three quarters of the total volume of concrete. In addition, cement, as cementing materials, only accounts for one quarter of the whole. The concrete has more volume stability and better durability than cement paste alone. In contrast, the price of sand and stone is much lower than that of cement, which greatly reduces the cost of concrete and has good technical and economic benefits. Each component material in concrete is a strict mix ratio design, according to a certain proportion of mixed together, so the nature of each component material has a great impact on the concrete, in the production of Concrete Pole Mould, must be in strict accordance with the GB/T4623-2006 standard for the ratio. Concrete can be roughly divided into the following three categories according to its surface density: 1, heavy concrete: dry apparent density is greater than 2600kg/m3; 2, ordinary concrete: dry apparent density between 1900-2500kg/m3, using sand and stone as aggregate, now used in the Pole Mold are such concrete, referred to as concrete. 3, light concrete: dry apparent density is less than 1900kg/m3, it includes light aggregate concrete, porous concrete and sand free large hole concrete, etc. Concrete according to its function and use can be classified into structural concrete, waterproof concrete, heat resistant concrete and acid resistant concrete and so on.

What are the minor faults that can easily occur with the CNC steel rolling welder? In the process of long-term overload use of the CNC steel rolling welder, strengthen the equipment fault repair, to maintain good operation of the equipment, reduce the equipment failure rate and extend the service life of the equipment is of great significance. In the process of using the equipment often appear a fault, as a manufacturer of roller welding machine for many years, we give you a small summary, so that in the future encounter these small problems will not be too worried, we slowly look at. First, the CNC steel rolling welder walking trolley track collapse. The walking trolley track of the outstanding steel ring rolling machine is a special kind of track. The walking track made of this material is not collapsible. If you buy a CNC rebar rolling welder with a walking track made of steel pipe or channel steel, then your CNC rebar winding machine will often collapse. At this point you can only replace the tracks yourself or ask the manufacturer to replace the walking tracks for you. Secondly, the spacing of the steel bars in the cage made by the CNC rebar rolling mechanism is not stable. The outstanding CNC rebar winding machine control system is equipped with three frequency converters to coordinate the rubber roller speed, the trolley travel speed and the wire feeding speed of the straightening machine. In this way, the rebar spacing in the rebar cage is generally very stable. You can try to reduce the working speed of the CNC steel roll welder to reduce the vibration amplitude of the cage during rotation and improve the specification. Thirdly, the steel cage rolling machine supports the deformation of the cage rubber rollers. If you buy a poor quality rebar roller welder, the deformation of the rubber rollers supporting the rebar cage is inevitable because the wall thickness of the rubber rollers is limited and so is the weight of all the supports. If you buy a top quality CNC rebar winding machine, try to observe if the base of your equipment supporting the rubber rollers is skewed, resulting in uneven forces on the rollers. Fourth, the tile base that holds the rubber rollers in place on the CNC rebar rolling welder is fractured. If the tile seat of your CNC steel roller welder fixing the rubber roller is broken, you can observe whether the rubber roller is firmly positioned in the steel cage. If the rubber roller is deformed, the tile holder tends to break at this point. Therefore, in daily use, you must pay attention to the maintenance of the CNC steel bar winding machine and often reinforce the screws to avoid unnecessary failures. Although there are few opportunities for common mechanical faults in the steel rolling machine, they should not be ignored. Instead, a comprehensive analysis is required to determine the root cause of the fault and to shorten the downtime as much as possible in order to give full play to the performance of the equipment.

What are the specific classifications of roll welders? The roll welder translates as concrete pile automatic wire cage welding machine. Many products are referred to simply as roll welder, such as welded steel bars, welded steel pipes, welded flanges, etc. They are collectively referred to as roll welder. There are actually more subdivided types of roll welder. We do automatic roll welder for forming reinforcement skeleton, mainly for forming reinforcement cages for precast concrete products, such as drainage pipes, inspection wells, electric poles, pipe piles, square culverts, square pole piles, photovoltaic piles, etc. The roll welder for steel rods is widely used, especially for the manufacture of cement pipes. Among them, the roll welder for cement pipes can be divided into push rod roll welder and tie rod roll welder. The push pole roll welder is easy to operate and low cost. The tie bar roll welder is superior to the push pole roll welder in terms of roundness and aesthetics. The pole roll welder is an integral tapered roll welder that changes the diameter by changing the threading diameter of the size die. The circle Cage Welding Machine is an equal diameter roll welder. The welding device wraps the steel and then fixes the rotating slide for welding. The principle is the same as the pole roll welder, but one isometric and one with taper, using different dies. The square pile roll welder is similar to the pipe pile roll welder and is a square pile roll welder after a change of mould sliding contact. The pile welding machine for square culverts is an automatic welding machine for steel bars based on rectangular shapes. In principle it can be made horizontally or vertically for skeleton welding. The horizontal rotary roll welder is widely used in China and is less costly.

The technical team is based on customers, constantly digging and researching, through unremitting efforts, to achieve the subversive innovation of the steel cage roller welder and fill the technical gaps in the domestic construction machinery. Amitycare has been positioned in the high-end quality, but the price is suitable. The steel cage roller welder has been stocked in major key projects of domestic highway, railroad and construction. The maintenance of the Steel Cage Welding Machine maintenance mode The processing speed of the cage welded by the steel cage roller welder is fast, the quality of the product is stable, and it can meet the requirements of the specification, and its cost is reduced because it does not need to lap, and it is mostly used for the production of the steel cage of the bored pile with the diameter of 40 to 200cm. The steel cage roller welder has a huge role in the production and must be maintained and serviced in a certain way in order to prolong its service life as much as possible. The maintenance of the equipment should be done from the following aspects. (1) to pay attention to check before starting the machine, such as whether the line is connected properly, whether there is leakage, whether the bolt is loose, etc. (2) In the process of starting the motor is strictly prohibited to cover, can not overheat, when this happens to be timely dispersed, cooling.

Spun Pile Cage Welding Machine working principle According to the construction requirements, the main reinforcing bar is first fixed through the round hole of the corresponding template in the fixed turntable to the corresponding hole in the mobile turntable. Weld the end of the winding bar to one main bar first. Then, by rotating the fixed turntable and the mobile turntable, the winding bar is wrapped around the main bar (the mobile turntable is rotated while moving backwards) and welded at the same time until it reaches the specified position at the end of the main bar, which forms the product reinforcement cage. The basic process of cage forming machine is as follows: loading → threading bars (main bars) → fixing → putting on hoop bars → starting welding → normal welding → ending welding → cutting off hoop bars → separating fixed disk → loosening bars → separating mobile disk → unloading cage → lowering hydraulic support → returning mobile disk The steel cage roller welding machine operation safety briefing 1. after the installation of the equipment, should ensure that the fixed disk and mobile disk rotation is normal, the support roller of the separation disk and the track completely contact, walking trolley walking without stalling phenomenon. 2.Electrical leakage protector and ground wire should be installed correctly and ensure its operation safety. 3.Operators must be professionally trained and fully understand the performance of the equipment before operating the equipment, non-operators are strictly prohibited from operating the equipment without permission. 4.Operators are strictly prohibited to wear fat, ribbons or clothing that can easily be involved in the equipment for production operations, female operators are strictly prohibited to wear skirts for equipment operation, long hair must be coiled up and fixed in the helmet; loading, transmission of steel and welding must wear protective equipment. 5.Each day before the equipment starts production, check the equipment condition: ① whether the emergency stop button is in the pressed state, whether the control power switch is in the closed state; ② whether the connection of each line is normal; ③ whether there is oil leakage; ④ whether the bolts and nuts are loose; especially the tensioning sleeve bolts at the driving shaft and driving gear, if the bolts are found to be loose, they should be tightened in time. ⑤ Whether there is too much dust in the electrical cabinet. 6.During the operation of the equipment, pay attention to check whether the motor is overheated; it is strictly forbidden to cover the electrical part and keep the heat dissipation smoothly. 7.It is strictly forbidden for non-production personnel to approach the equipment when the machine is in operation, paying special attention to the danger of clothes and arms being caught in the equipment. 8, regular maintenance of equipment: ① every 1 to 2 months on the circuit breaker, motor terminals, electrical box terminals, in the case of power cut off to re-tighten; all the bolts, nuts to re-tighten; on the reducer, hydraulic station oil amount to check, to safety instructions If there is oil leakage to be repaired in a timely manner; ② once a week on all the lubricating oil nozzle injection grease; with a paint brush or breeze blower to remove the dust in the electrical cabinet, it is strictly prohibited to use wet cloth, wet brush, water or compressed air to electrical equipment in the electrical cabinet for dust cleaning operations. 9, the electrical control cabinet is strictly prohibited in the water, to ensure that the electrical control cabinet is not rained on. 10.After the production is over, move the disk back into place, close the control power switch and oil pump switch, and close the total power welder power switch. 11, if the equipment is not used for a long time, the control cabinet should be turned off all low-voltage circuit breakers (air switch)

What happened to the pc bar bending machine not resetting? How to solve it?

Pipe/pile rolling welder machine-Precast concrete cage welding machine As the key equipment for the production of pipe piles and electric poles, the roll welder for electric poles has undergone many years of modernization and has reached maturity and can basically meet the production requirements. However, there is still more room for improvement in terms of details, such as high energy consumption, large amount of consumables (copper plate), welding speed is not fast enough, long auxiliary time, high labor intensity of operators, as well as the short service life of individual mechanisms, welding quality needs to be improved. In this regard, for the above shortcomings, our company has achieved better results after a lot of practical research. In this paper, we explain how to reduce the energy consumption, improve the production efficiency and welding quality, and extend the durability of the equipment of the pole pile rolling welder. Our company has made improvements in the following three aspects: improving welding speed, reducing auxiliary time and reducing manual operation. Improving welding speed One of the most effective ways to improve productivity is to increase welding speed, which is predicated on increasing the input density of welding current. The use of DC power source when the current is not zero point and not limited by the AC frequency, no alternating magnetic field generated, and can improve the density of input current, so the use of DC power source to further improve the welding speed. In addition, without increasing the power of the welding power supply, increase the welding circuit conductive area and cooling strength to prevent overheating of the circuit is also an effective way to improve the welding speed. Adding automatic locking and unlocking device for steel rod ends on the tractor The current production of electric pole pipe pile roll welder has realized the function of automatic locking and unlocking of steel skeleton end, with automatic unloading of steel skeleton and automatic return function of tractor car, only one person can operate to make steel skeleton, thus improving the production efficiency. Application of automatic height-adjusting bracket cage In the early stage, the height of the cage holder of the pipe pile roller welder was adjusted manually according to the current specifications of the steel skeleton, which required manual adjustment of the height of the cage holder every time the specifications were changed, which affected the production efficiency to a certain extent. The new cage carrier can adjust the height automatically, and the cage carrier can be adjusted automatically according to the bottom height of the steel skeleton when changing specifications, which saves the auxiliary time and further improves the production efficiency. Automatic cage unloading device After the Concrete Pipe Welding Machine is finished, the cage unloading flap automatically rises and the cage carrier then falls down to drop the welded steel skeleton onto the cage unloading flap, and the steel skeleton rolls down by its own gravity without human operation, which improves the production efficiency and reduces the labor intensity of the operator. skeleton. Fast automatic return of the tractor In the early days, the tractor of the pole cage welding machine for electric pole and pipe pile was mostly pushed back by human power, with low production efficiency and high labor intensity, while the rolling welder of the present production is mostly fast and automatic return, and there are also many enterprises to add automatic return device for the tractor of the early rolling welder itself, which improves the production efficiency. Use the new type of bar piercing pipe The roll welder for electric pole pile sets up the front and back of the two bar-wearing discs, and sets up the bar-wearing tube on the bar-wearing disc, which needs to be aligned twice to wear the steel bar to the predetermined position, taking up long time and low production efficiency, but now it is improved to the whole bar-wearing tube, which can wear the steel bar to the predetermined position only once, saving half of the time and further improving the production efficiency. Large roll welder uses pneumatic positioning device on the top of the winding disc Due to the large diameter of the winding disc of the large roll welder, when replacing the winding disc, the operator needs to climb up to the equipment to operate the positioning device of the winding disc, which is not only troublesome but also dangerous, but now it is improved to pneumatic positioning device, the operator only needs to press the pneumatic button to easily operate the positioning device of the winding disc on top of the equipment.
