Description

Technical Field

[0001] This invention relates to the field of automotive bracket stamping, and more specifically, to multi-station automotive bracket stamping equipment and processes. Background Technology

[0002] As a crucial connecting component of the automotive chassis and body structure, the automotive bracket undertakes multiple functions, including load transfer, weight support, and shock absorption. Its complex structure, high strength requirements, and stringent precision demands necessitate high-volume, high-efficiency production methods in modern automotive manufacturing to meet market demands. Multi-station stamping equipment typically employs a production mode where a single upper die corresponds to multiple lower die stations. A continuous conveyor system sequentially feeds multiple sets of lower dies into the stamping area of ​​the upper die, achieving high-efficiency mass production. The core concept of this equipment configuration is to fully utilize the working capacity of the upper die, improving equipment efficiency and output through the continuous flow of the lower dies. Once a set of lower dies completes stamping, it is immediately conveyed to the next station or removed from the stamping area, while the next set of lower dies awaiting processing quickly moves into the stamping position, forming a continuous production cycle. During stamping, the upper die applies enormous stamping force to the lower die; therefore, the lower die must maintain an absolutely stable position and posture during stamping, otherwise, the forming accuracy and product quality will be affected.

[0003] Existing multi-station stamping equipment generally uses screw drives or conveyor belt drives to achieve the position change of the lower die. These conveying methods can lead to insufficient stability and positioning errors of the lower die when facing huge stamping pressure. Although the screw drive system has the characteristic of relatively accurate positioning, it is essentially designed to realize motion transmission, not a dedicated fixed clamping mechanism. When the upper die applies huge stamping pressure, the fit clearance between the screw and nut, the bending deformation of the screw itself, and the slight deformation of the support structure can all cause uncontrollable displacement of the lower die. Although this displacement may only be tens of micrometers, it is fatal for automotive bracket stamping parts with extremely high precision requirements, resulting in quality problems such as out-of-tolerance product dimensions, shape deformation, and uneven mating surfaces. This lack of stability will cause a series of production problems such as low product qualification rate, accelerated die wear, and increased equipment failure rate. In addition, the lower die replacement operation of traditional equipment is extremely cumbersome, usually requiring multiple steps such as machine shutdown, disassembly, reinstallation, and debugging. Each die replacement consumes a lot of time and manpower, affecting the continuity of the production line and the overall efficiency. Summary of the Invention

[0017] This invention provides a multi-station stamping process for automotive brackets, comprising the following steps:

[0018] The motor drives the belt and pulley to rotate the lead screw, realizing the continuous movement of the conveyor frame and the sequential conveying of multiple sets of lower dies. When each set of lower dies is transported to the bottom of the upper die, the hydraulic cylinder drives the upper die to move down to perform the stamping operation. This multi-station continuous stamping design fully utilizes the processing capacity of a single upper die. Through the streamlined conveying of the lower dies, uninterrupted batch production of workpieces is achieved, improving the working efficiency and output capacity of the equipment and eliminating the idle waiting time in traditional single-station equipment.

[0019] Once the lower die reaches the stamping position, the receiving plate moves the pressure rod downward to pre-press the bidirectional rod, triggering the directional flow of hydraulic oil in the hydraulic pipeline. Through the coordinated action of the first and second slide rods, the bidirectional locking of the conveyor frame is achieved. This hydraulic positioning system can provide a strong constraint force to the lower die at the moment of stamping, solving the problem of insufficient stability of traditional screw or conveyor belt conveying methods when subjected to large-tonnage stamping pressure. It effectively eliminates the displacement, vibration and deformation of the lower die, ensures the dimensional accuracy and shape accuracy of the stamped parts, and improves the stability and consistency of product quality.

[0020] Through a switching mechanism consisting of a push rod, a ball clamp, and a ring spring, and a rotating positioning design of the vertical rod, the system can switch between two working modes: disassembly and installation. The disassembly and installation process is hydraulically driven. The vertical rod's compression of the pressure block triggers the flow of hydraulic oil in the composite pipeline network, achieving synchronous extension and retraction of the four sets of horizontal rods, completing the automatic clamping and release of the lower mold. The entire disassembly and installation process is simple and quick to operate, improving the flexibility of the production line and market responsiveness, enabling enterprises to meet the market demands of multiple varieties and small batches.

[0021] (III) Beneficial Effects

[0022] Compared with existing technologies, this invention provides a multi-station stamping forming equipment and process for automotive brackets, which has the following beneficial effects: This invention designs a bidirectional positioning and fixing system based on hydraulic transmission, which solves the problems of insufficient stability of the lower die during stamping and cumbersome disassembly of the lower die in traditional equipment. When the conveyor frame transports the lower die to the stamping position directly below the upper die, the system drives the pressure rod to pre-press the bidirectional rod through the downward movement of the receiving plate, triggering the directional flow of hydraulic oil in the closed hydraulic circuit composed of the first hydraulic pipe, the second hydraulic pipe and the connecting pipe, realizing the synchronous and coordinated action of the first slide rod and the second slide rod. This hydraulically driven positioning mechanism can provide a strong constraint force to the conveyor frame at the moment of stamping, effectively eliminating the displacement, vibration and deformation problems caused by traditional screw drive or conveyor belt drive systems when subjected to large-tonnage stamping pressure. The bidirectional rod, together with the sliding sleeve and the elastic buffer design of the upper and lower pressure springs, ensures the smooth and reliable positioning action. When the upper die applies stamping pressure, the hydraulic positioning system can firmly lock the conveyor frame in a fixed position, eliminating small displacements that may affect stamping accuracy, ensuring that the quality of the stamped parts meets the design requirements, and improving the product qualification rate and production stability.

[0023] This invention achieves rapid replacement of the lower die through an integrated disassembly and assembly mechanism, improving the die-changing efficiency of the production line. The disassembly and assembly mechanism adopts a mechanical structure with a push rod, a ball catcher, and a ring spring. The working state is switched by the up and down movement of the hydraulic cylinder. When the ball catcher overcomes the elastic force of the ring spring and moves to the lower position, the vertical rod can extend to perform disassembly and assembly operations, avoiding mutual interference with normal stamping operations. The rotation positioning design of the vertical rod allows the operator to select the disassembly or installation mode with a simple rotation operation, and perform the corresponding hydraulic drive operation by aligning with the first or second pressure block. The disassembly and assembly process adopts a hydraulic transmission system. Through the hydraulic network composed of vertical tubes, damping tubes, and horizontal tubes, the synchronous and coordinated movement of the four sets of horizontal rods is achieved, ensuring uniform clamping and release of the lower die. The sealing control design of the horizontal rod and spring in the damping tube solves the problem of hydraulic oil flow control. The spring realizes the sealing and release between the horizontal rod and the tube wall, ensuring the reliability and durability of the hydraulic system, improving production efficiency and equipment utilization, and enabling enterprises to meet the market demand of multiple varieties and small batches.

[0043] This invention enables the positioning of the conveyor frame 21 and the convenient assembly and disassembly of the lower die 22. Workers place the workpieces to be stamped into each set of lower dies 22. The motor 14 starts, driving the pulley 15 via the belt 16 to rotate the lead screw 13 synchronously. The lead screw 13 drives the conveyor frame 21 to transport the workpieces. When each set of lower dies 22 is transported directly below the upper die 18, the hydraulic cylinder 17 starts, driving the upper die 18 downwards to stamp the workpieces within the lower die 22. The multi-set lower die 22 conveying design allows for continuous stamping of the workpieces; when a set of lower dies... When the 22 is transported to the lower part of the upper die 18, the conveyor frame 21 needs to be positioned and fixed for accurate stamping. When the hydraulic cylinder 17 moves down, the telescopic end of the hydraulic cylinder 17 will drive the receiving plate 19 to move down synchronously. The receiving plate 19 will then drive the pressure rod 212 to slide down along the stamping machine 11. The pressure rod 212 presses the bidirectional rod 28 in the conveyor frame 21 at this position one step before the upper die 18. The bidirectional rod 28 on this side is pressed and drives the sliding sleeve 29 to slide down along the conveyor frame 21. At this time, the upper pressure spring 210 is stretched and the lower pressure spring 211 is compressed. The lower end of the bidirectional rod 28 faces the second hydraulic cylinder. The second slide rod 27 inside the pressure pipe 24 is compressed, and the first hydraulic pipe 23, the second hydraulic pipe 24, and the connecting pipe 25 are all filled with the connecting pipe 25. When the second slide rod 27 is compressed and moves downward, the lower part of the bidirectional rod 28 on this side is inserted into the second hydraulic pipe 24. The hydraulic oil in the second hydraulic pipe 24 is pressurized and flows into the first hydraulic pipe 23 through the connecting pipe 25, compressing the bottom of the first slide rod 26. The first slide rod 26 is compressed and moves upward, and the upper part of the first slide rod 26 is inserted into the conveyor frame 21 on this side, compressing the bottom of the bidirectional rod 28 on one side of the first slide rod 26. When rod 28 is pressed, it drives the sliding sleeve 29 to move upward along the conveyor frame 21. At this time, the upper compression spring 210 is compressed and the lower compression spring 211 is stretched, thus fixing the position of the conveyor frame 21. The lower die 22 continues to move downward to perform stamping work on the workpiece in the upper die 18. After the stamping is completed, the hydraulic cylinder 17 drives the upper die 18 and the receiving plate 19 to reset. At this time, the upper compression spring 210 and the lower compression spring 211 rebound to reset the positioning mechanism, release the fixation of the conveyor frame 21, and then the conveyor frame 21 can transport the next set of lower dies 22 to move below the upper die 18 to realize the next stamping work.

[0044] When the lower die 22 needs to be replaced, it can be done through the disassembly and assembly mechanism. During normal stamping operation, the vertical rod 324 is in the retracted state, and the retaining ball 32 is located above the annular spring 322. At this time, the vertical rod 324 will not obstruct the operation of the pressure rod 212. When the lower die 22 needs to be replaced, the hydraulic cylinder 17 needs to drive the receiving plate 19 to continue to move upward, so that the upper end face of the ejector rod 31 abuts against the side wall of the stamping machine 11. Continue to move upward until the retaining ball 32 on the ejector rod 31 overcomes the elastic force of the annular spring 322 and moves to the annular spring 212. Below the spring 322, the vertical rod 324 is longer than the pressure rod 212. When it is necessary to disassemble the lower mold 22, the vertical rod 324 is rotated to align with the second pressure block 316. The hydraulic cylinder 17 is activated, and the hydraulic cylinder 17 drives the receiving plate 19 to move downward, thereby driving the top rod 31 and the lower vertical rod 324 to move downward synchronously. The vertical rod 324 squeezes the second pressure block 316. The vertical tube 39, the first damping tube 313, the second damping tube 318, the horizontal tube 34, and multiple sets of connecting tubes are also present. The pipes 313, the second damping tube 318, and the corresponding four sets of transverse pipes 34 are all filled with hydraulic oil. The second pressure block 316 moves downward under pressure, and the second connecting spring 317 is compressed. At this time, the hydraulic oil below the second pressure block 316 is squeezed into the second damping tube 318. The second crossbar 319 inside the second damping tube 318 is released from its sealing connection with the inner wall of the second damping tube 318 under pressure. The second spring 320 is half stretched and half compressed, and the hydraulic oil flows through the second damping tube 318. The hydraulic oil is inserted into the second hydraulic chamber 38 corresponding to the four sets of transverse tubes 34. The hydraulic oil in the second hydraulic chamber 38 is pressurized and squeezes the side wall of the first partition 36. At this time, the four sets of transverse rods 35 move outward simultaneously and move out of the lower mold 22, releasing the fixation of the lower mold 22. Then the lower mold 22 can be disassembled. The hydraulic cylinder 17 is lifted and the second spring 320 rebounds, realizing the sealing state between the second cross rod 319 and the second damping tube 318 again. Then, it is ready to enter the disassembly work of the next set of lower molds 22.

[0045] When the lower mold 22 needs to be installed, rotate the vertical rod 324 to align it with the first pressure block 311. Then, activate the hydraulic cylinder 17 to push the receiving plate 19 downward, which in turn drives the top rod 31 and the lower vertical rod 324 to move downward simultaneously. The vertical rod 324 presses against the first pressure block 311, causing the first pressure block 311 to move downward under pressure. The first connecting spring 312 is compressed, and the hydraulic oil below the first pressure block 311 is squeezed into the first damping tube 313. The first horizontal rod 314 in the first damping tube 313 is released from its sealing connection with the inner wall of the first damping tube 313 under pressure. The first spring 315 is half stretched and half compressed. The hydraulic oil flows through the first damping tube 313 into the first hydraulic chamber 37 corresponding to the four sets of horizontal tubes 34. The hydraulic oil in the first hydraulic chamber 37 is pressurized and squeezes the first partition plate 36. At this time, the four sets of horizontal rods 35 extend simultaneously and insert into the lower mold 22. The lower die 22 is fixed, thus enabling its installation. After one set of lower dies 22 is installed, the hydraulic cylinder 17 is lifted, and the first spring 315 rebounds, causing the first horizontal bar 314 to re-seal with the first damping tube 313. Then, the installation of the next set of lower dies 22 begins. Under the action of the first damper, even if the pressure is removed, the horizontal bar 35 cannot return to its original position, thus maintaining the fixation of the lower die 22. In summary, this enables the rapid assembly and disassembly of the lower die 22. After the assembly and disassembly of the lower die 22 are completed, the hydraulic cylinder 17 drives the vertical bar 324 to move downward continuously. The vertical bar 324 presses the upper surface of the first pressure block 311 or the second pressure block 316. However, since the first pressure block 311 or the second pressure block 316 is already fixed in position, the vertical bar 324 is pressed upward, causing the ball 32 to overcome the elastic force of the ring spring 322 and return to the top of the ring spring 322, thus allowing subsequent stamping operations to proceed.
