Description

Technical Field

[0001] This invention relates to the field of metal sheet processing technology, specifically to a pressing machine for hollow square cylinder bodies of pipe pile steel molds. Background Technology

[0002] Steel molds for pipe piles are the core tooling equipment in the production of prestressed concrete pipe piles. The edge forming quality of the hollow cylinder directly determines the forming accuracy, structural strength, and service life of the pipe pile. With the continuous improvement of the construction industry's requirements for the quality of pipe pile products, the market has put forward higher standards for the edge pressing processing accuracy, production efficiency, and equipment versatility of the hollow cylinder of the pipe pile steel mold.

[0003] Currently, the steel formwork blanking equipment commonly used in the industry for pipe piles faces numerous technical bottlenecks in practical applications. From the perspective of equipment support structure, traditional frames are mostly lightweight designs with insufficient support rigidity, making them prone to resonance and deformation during high-pressure rolling operations. This leads to misalignment of the pressure roller positioning accuracy, affecting the edge forming quality of the sheet metal. In the material conveying stage, the transmission system design of existing roller conveyor feeding mechanisms has significant flaws. The synchronization of conveyor roller speeds is poor, easily causing jamming and deviation problems during sheet metal conveying, hindering continuous feeding and unloading, and restricting the cycle efficiency of the production line.

[0004] Regarding processing accuracy control, existing equipment lacks intelligent detection and parameter matching mechanisms. Sheet size measurement and process parameter setting rely entirely on manual operation, leading to significant subjective errors. Furthermore, there is no effective quality inspection process after edge pressing, resulting in a large number of defective products flowing into subsequent processes, causing a double waste of materials and time. In the positioning and clamping stage, traditional rigid positioning mechanisms cannot adjust the clamping force according to the sheet thickness, easily causing surface damage or positioning failure, leading to warping and displacement of the sheet during edge pressing, further reducing processing accuracy.

[0005] From the perspective of equipment versatility and forming process, existing edge pressing dies are mostly customized fixed structures. One machine can only be adapted to the processing of one specification of cylinder. When production needs change, the entire set of dies needs to be replaced, which not only increases the equipment investment cost, but also prolongs the production changeover time. At the same time, the traditional stamping edge pressing process is prone to stress concentration at the edge of the sheet metal, forming defects such as burrs and wrinkles, which require additional grinding processes and affect production efficiency.

[0006] In summary, traditional steel formwork blank pressing equipment for pipe piles can no longer meet the production needs of modern manufacturing, which require high precision, high efficiency, and high versatility. Developing a new type of pressing machine with stable support, continuous conveying, precise positioning, intelligent detection, multi-specification adaptability, and automated control has become an urgent need for the industry. Summary of the Invention

[0007] To address the shortcomings of existing technologies, this invention provides a steel mold blanking machine for pipe piles, which solves the common problems in traditional steel mold blanking equipment for pipe piles, such as insufficient frame rigidity, asynchronous feeding, lack of full-process inspection, poor positioning adaptability, low mold versatility, and poor mechanism control connection.

[0037] As an optimized solution, an integrated electrical control box is fixed to one side of the upper surface of the support base.

[0038] Compared with the prior art, the beneficial effects of the present invention are:

[0039] 1. The high rigidity design of the frame support system ensures stable equipment operation.

[0040] The multi-level support structure, consisting of a support base, conveyor support frame, square frame, and main frame, adopts a combination of grounding and bolted installation to form a stable force-bearing system. The transversely symmetrical main frame is reinforced by connecting bridge plates, intermediate support plates, and bottom support plates, which can effectively bear the weight and operational impact of the pressing actuator, preventing deformation or vibration of the equipment during high-speed operation and high-pressure rolling, and providing a stable installation foundation for the precise operation of each actuator.

[0041] 2. The roller conveyor feeding mechanism adopts a synchronous transmission design to achieve stable and continuous conveying of the sheet metal.

[0042] Two sets of roller conveyor feeding mechanisms are responsible for loading and unloading respectively. The conveyor rollers on the same side form a synchronous transmission system through the transmission sprocket and transmission chain, which is uniformly driven by the conveyor drive motor to ensure that all conveyor rollers rotate at the same speed and avoid jamming or deviation of the sheet material during the conveying process. The C-type protective end cap not only protects the transmission components, but also simplifies the maintenance and operation of the equipment.

[0043] 3. Closed-loop control design of the vision recognition system improves processing accuracy and quality control capabilities.

[0044] The front-facing recognition camera can accurately detect the shape and size of the sheet material during the feeding stage and transmit the data to the control host. The control host automatically matches the edge pressing process parameters to achieve adaptive adjustment between the edge pressing mold and the sheet material size, avoiding processing defects caused by manual parameter setting errors. The rear-facing recognition camera detects the edge forming effect and dimensional accuracy after edge pressing, forming a closed loop of size recognition, parameter matching and quality inspection, which significantly improves the pass rate of edge-pressed finished products and reduces subsequent rework costs.

[0045] 4. The positioning and clamping mechanism adopts a dynamic adaptive design, which can achieve precise positioning and conveying assistance of the sheet metal.

[0046] The symmetrical and staggered strip positioning plates, together with the dynamic positioning components, form a comprehensive positioning and clamping system: the positioning telescopic cylinder drives the positioning pressure roller to fit against the surface of the plate, and the swing side plate maintains a stable and adjustable clamping force under the elastic action of the tension spring, which can adapt to the positioning requirements of plates of different thicknesses and effectively prevent the plate from shifting or warping due to force during the pressing process; at the same time, the positioning pressure roller that rotates synchronously with the plate complements the function of the conveying roller, ensuring the smooth conveying of the plate in the pressing area and avoiding the problem of conveying interruption.

[0047] 5. The modular adjustable edge clamping actuator enables high-precision edge clamping and multi-specification adaptation.

[0048] The dual-shaft motor drives the drive shaft to rotate via a bevel gear transmission unit. The staggered distribution of threaded and smooth sections on the drive shaft allows for separate control of the lifting movements of the upper and lower lifting seats, ensuring the motion accuracy of the upper and lower forming rollers and guaranteeing uniform force on the edges of the sheet metal. The top support telescopic cylinder of the upper forming roller drives the top support die to move radially, adapting to cylindrical sheet metal with different inner diameters. The extrusion telescopic cylinder of the lower forming roller drives the extrusion die to move radially, adapting to cylindrical sheet metal with different outer diameters. This gives the equipment the ability to process multi-specification pipe pile steel mold cylinders, improving its versatility and applicability. The upper and lower rotating motors drive the rollers to rotate, and combined with the chamfered design of the die edges, achieve roll forming processing. Compared to traditional stamping edge pressing, the formed sheet metal edges are burr-free and wrinkle-free, resulting in higher forming quality.

[0049] 6. Integrated system control design enhances equipment automation and ease of operation.

[0050] The integrated electrical control box and the control host form a unified control center, which coordinates and controls the entire process of feeding, positioning, pressing, and detection, realizing the automated operation of pressing operations, greatly reducing manual intervention and reducing the labor intensity of operators; the action commands of each mechanism are uniformly issued by the control system, ensuring smooth connection between each process and improving the overall processing efficiency.

Detailed Implementation

[0062] The embodiments of the technical solution of the present invention will now be described in detail with reference to the accompanying drawings. These embodiments are merely illustrative of the technical solution of the present invention and are therefore intended to limit the scope of protection of the present invention.

[0063] like Figures 1 to 9 As shown, the steel formwork blank pressing machine for pipe piles includes a frame support system, a roller conveyor feeding mechanism, a vision recognition system, a positioning and pressing mechanism, and a pressing execution mechanism.

[0064] The frame support system includes a support base 1 and two conveyor support frames 2. The support base 1 is a square base that is horizontally grounded. The two conveyor support frames 2 are located on the horizontal sides of the support base 1. The conveyor support frames 2 are square frames that are grounded at their lower ends.

[0065] The frame support system also includes two rectangular frames 3, which are fixed to the outer middle sections of the two conveyor support frames 2 respectively, and the lower ends of the rectangular frames 3 are also grounded.

[0066] The roller conveyor feeding mechanism is provided in two sets. The two sets of roller conveyor feeding mechanisms are respectively installed on two conveyor support frames 2. The two sets of roller conveyor feeding mechanisms are used for pressing edge feeding and pressing edge unloading, respectively.

[0067] Each set of roller conveyor feeding mechanism includes several conveying rollers 4, which are arranged at equal intervals in the horizontal direction and extend in the vertical direction. Each conveying roller 4 has a connecting shaft 5 welded to its longitudinal end face. The connecting shaft 5 passes through the longitudinal inner wall of the conveying support frame 2 and extends to its outer side.

[0068] Each end of the connecting shaft 5 is fixed with a transmission sprocket 6, and a transmission chain 7 is fitted onto several transmission sprockets 6 located on the same side.

[0069] Each longitudinal end face of the conveyor support frame 2 is fixed with a C-shaped protective end cap 8. A conveyor drive motor 9 is fixed on the longitudinal outer wall of the C-shaped protective end cap 8. The output shaft of the conveyor drive motor 9 is fixed to the side end face of the last transmission sprocket 6.

[0070] The visual recognition system includes a front recognition camera 10 and a rear recognition camera 11. The front recognition camera 10 is fixed on the inner top surface of one of the square frame frames 3, and the rear recognition camera 11 is fixed on the inner top surface of the other square frame frame 3. The front recognition camera 10 can accurately identify the length, width and thickness of the board during the feeding process, and the rear recognition camera 11 can perform quality inspection on the chamfer size, flatness and burr-free condition of the edge after the edge pressing is completed.

[0071] Each frame 3 has a control host 12 fixed on its longitudinal side wall.

[0072] The frame support system also includes four symmetrical main frames 13, each with a hollow interior. The lower end of the main frame 13 is fixed to the upper surface of the support base 1 by bolts.

[0073] Connecting bridge plates 14 are fixed on the upper surfaces of the two horizontally opposite main frames 13. Each connecting bridge plate 14 has a middle support plate 15 and a bottom support plate 16 arranged below it. The two ends of the middle support plate 15 are welded to the opposite horizontal outer walls of the two main frames 13.

[0074] The pressing mechanism includes two dual-axis motors 17, which are fixed in the middle of the upper surface of the connecting bridge plate 14. Each dual-axis motor 17 has a transmission box 18 on both sides in the lateral direction, and the lower end of the transmission box 18 is fixed on the upper surface of the connecting bridge plate 14.

[0075] Each transmission box 18 is equipped with a bevel gear transmission unit, and the output shaft end of the dual-output shaft motor 17 passes through the side wall of the transmission box 18 and is connected to the bevel gear transmission unit.

[0076] The edge pressing mechanism also includes an upper forming roller and a lower forming roller.

[0077] The upper forming roller includes an upper roller shaft 19, which extends longitudinally. An intermediate base 20 is welded to the middle of the upper roller shaft 19. The intermediate base 20 is a hollow column base.

[0078] Several top support telescopic cylinders 21 are fixed on each longitudinal end face of the intermediate base 20. An annular top support pressing die 22 is fixed at the telescopic end of the several top support telescopic cylinders 21. The top support pressing die 22 is slidably sleeved on the upper roller shaft 19. The outer edge of the top support pressing die 22 is chamfered.

[0079] Two upper lifting seats 23 are provided on both sides of the upper roller shaft 19. The upper roller shaft 19 is rotatably installed between the two upper lifting seats 23. An upper rotating motor 24 is fixed on the longitudinal outer wall of one of the upper lifting seats 23. The output shaft end of the upper rotating motor 24 passes through the upper lifting seat 23 and is fixed to the side end face of the upper roller shaft 19.

[0080] The lower forming roller includes a lower roller shaft 25, which is located directly below the upper roller shaft 19. The lower roller shaft 25 extends longitudinally, and two side bases 26 are welded to the outer peripheral walls of the lower roller shaft 25 near both ends.

[0081] Several extrusion telescopic cylinders 27 are fixed on the longitudinal inner end face of each side base 26. An annular extrusion die 28 is fixed at the telescopic end of the extrusion cylinders 27. The extrusion die 28 is slidably sleeved on the lower roller shaft 25. The inner edge of the extrusion die 28 is chamfered.

[0082] Two lower lifting seats 29 are provided on both sides of the lower roller shaft 25. The lower roller shaft 25 is rotatably installed between the two lower lifting seats 29. A lower rotating motor 30 is fixed on the longitudinal outer wall of one of the lower lifting seats 29. The output shaft end of the lower rotating motor 30 passes through the lower lifting seat 29 and is fixed to the side end face of the lower roller shaft 25.

[0083] Two drive shafts 31 are provided between each set of connecting bridge plates 14 and bottom support plates 16. The middle section of the drive shaft 31 passes through the middle support plate 15, and the upper end of each drive shaft 31 is connected to the bevel gear transmission unit.

[0084] Each drive shaft 31 is divided into upper and lower sections by the middle support plate 15, which are threaded sections and smooth sections respectively. If the upper half of one drive shaft 31 is a threaded section and the lower half is a smooth section, then the upper half of the other two drive shafts 31 that are horizontally or vertically opposite to it are smooth sections and the lower half is a threaded section.

[0085] The upper half of the drive shaft 31 passes through the upper lifting seat 23 and the lower half passes through the lower lifting seat 29. The threaded section of the drive shaft 31 is threadedly engaged with the upper lifting seat 23 and the lower lifting seat 29 respectively, and the smooth section of the drive shaft 31 is slidably fitted on the upper lifting seat 23 and the lower lifting seat 29 respectively.

[0086] The dual-output shaft motor 17 drives the drive shaft 31 to rotate, which can drive the upper lifting seat 23 and the lower lifting seat 29 to rise and fall synchronously in opposite directions, thereby driving the upper forming pressure roller and the lower forming pressure roller to move in opposite directions to complete the edge pressing operation.

[0087] The positioning and pressing mechanism includes four strip positioning plates 32. The four strip positioning plates 32 are symmetrically fixed on the four main frames 13 in pairs. The horizontally symmetrical strip positioning plates 32 are respectively located on both sides of the upper forming roller and the lower forming roller, and the vertically symmetrical strip positioning plates 32 are respectively located on the upper and lower sides of the conveying roller 4. The two vertically opposite strip positioning plates 32 are staggered.

[0088] Each of the strip positioning plates 32 located at the top is equipped with a dynamic positioning component, which includes three positioning telescopic cylinders 33, which are fixed on the inner top surface of the strip positioning plate 32.

[0089] Each positioning telescopic cylinder 33 has a positioning seat 34 fixed at its lower telescopic end. Two fixed connecting shafts 35 are fixed between two adjacent positioning seats 34. Each fixed connecting shaft 35 is rotatably fitted with a swing side plate 36. The two swing side plates 36 are symmetrically arranged at a certain included angle and are elastically connected by two symmetrical tension springs 37.

[0090] Each swing side plate 36 has a rotating mounting bracket 38 fixed to its end, and a positioning pressure roller 39 is rotatably mounted on the rotating mounting bracket 38.

[0091] Each of the strip positioning plates 32 located below is also equipped with a dynamic positioning component.

[0092] The dynamic positioning component can press and position the metal sheet from both the top and bottom sides during the continuous pressing and feeding and unloading process. At the same time, the staggered positioning rollers 39 can also supplement the conveying rollers 4 to ensure the continuity of conveying.

[0093] An integrated electrical control box 40 is fixed to one side of the upper surface of the support base 1.

[0094] When the invention is in use: after the equipment is started, the integrated electrical control box 40 issues a command to start the conveyor drive motor 9. Its output shaft drives the last transmission sprocket 6 to rotate. Through the meshing transmission of the transmission chain 7, it synchronously drives the connecting shaft 5 of all conveyor rollers 4 on the same side to rotate, thereby driving the conveyor rollers 4 to rotate. The operator hoists and places the metal sheet to be pressed onto the conveyor rollers 4 of the feeding group. The rotating conveyor rollers 4 drive the sheet to be smoothly conveyed in the longitudinal direction and enter the pressing operation area of ​​the equipment.

[0095] During the feeding and conveying process, the sheet material passes through the detection range of the front-mounted recognition camera 10. The front-mounted recognition camera 10 accurately identifies the shape and size of the sheet material and transmits the detection data to the control host 12 on the side wall of the square frame 3 in real time. The control host 12 automatically matches the subsequent edge pressing process parameters according to the sheet material size parameters, providing data basis for adjusting the action of the edge pressing actuator.

[0096] When the sheet material is conveyed between the upper forming roller and the lower forming roller, the positioning and clamping mechanism is activated; the positioning telescopic cylinders 33 on the upper and lower sets of strip positioning plates 32 extend synchronously, pushing the positioning seat 34 to move down or up, driving the fixed connecting shaft 35 and the swing side plate 36 to move, so that the positioning roller 39 on the rotating mounting frame 38 fits against the upper and lower surfaces of the sheet material; during this process, the two symmetrically arranged swing side plates 36 maintain a stable clamping force under the elastic action of the tension spring 37, ensuring that the sheet material is accurately positioned; at the same time, the positioning rollers 39 arranged in a staggered manner rotate synchronously with the conveying of the sheet material, which not only prevents the sheet material from shifting or warping during the pressing process, but also supplements the conveying function of the conveying roller 4, ensuring the continuity of the sheet material conveying.

[0097] After the positioning and clamping are completed, the edge pressing actuator starts to operate: the dual-output shaft motor 17 starts, and its output shaft drives the bevel gear transmission unit in the transmission box 18 to rotate, which in turn drives the drive shaft 31 below the connecting bridge plate 14 to rotate; since the drive shaft 31 is divided by the intermediate support plate 15, the threaded section and the smooth section are staggered. When the drive shaft 31 rotates, the threaded section forms a threaded engagement with the upper lifting seat 23 and the lower lifting seat 29, which drives the upper lifting seat 23 and the lower lifting seat 29 to move synchronously in opposite directions, so that the upper forming pressure roller and the lower forming pressure roller approach each other;

[0098] At the same time, the upper rotating motor 24 and the lower rotating motor 30 drive the upper roller shaft 19 and the lower roller shaft 25 to rotate respectively; the top support telescopic cylinder 21 of the upper forming pressure roller extends and pushes the annular top support pressing die 22 to slide radially outward along the upper roller shaft 19 to match the inner diameter of the plate; the extrusion telescopic cylinder 27 of the lower forming pressure roller extends and pushes the annular extrusion die 28 to slide radially inward along the lower roller shaft 25 to match the outer diameter of the plate.

[0099] After the top support edge pressing die 22 and the extrusion edge die 28 are adjusted to the preset position, the rotating upper and lower forming rollers roll the edge of the plate. The edge forming process of the hollow cylindrical plate of the pipe pile steel mold is completed by using the chamfer on the outside of the top support edge pressing die 22 and the chamfer on the inside of the extrusion edge die 28.

[0100] After the edge pressing is completed, the conveying roller 4 continues to drive the sheet material to be conveyed, passing through the detection range of the rear recognition camera 11; the rear recognition camera 11 performs a comprehensive inspection of the edge pressing quality of the sheet material, checks the edge pressing dimensional accuracy, edge forming effect and other indicators, and transmits the detection data to the control host 12; the control host 12 judges the edge pressing quality according to the preset standard and distinguishes between qualified products and unqualified products.

[0101] The sheet material that passes the quality inspection is smoothly conveyed out by the conveyor roller 4, completing the entire edge pressing process; if the inspection determines that it is unqualified, the control host 12 will issue a warning signal to remind the operator to carry out subsequent processing.

[0102] Throughout the entire operation, the support base 1, conveyor support frame 2, square frame 3, and main frame 13 of the frame support system provide a stable installation foundation and support for each mechanism, ensuring the stability of equipment operation; the actions of each mechanism are uniformly coordinated by the integrated electrical control box 40 and the control host 12 to achieve automated and high-precision edge pressing operations.
