Description

Technical Field

[0001] This application relates to the field of cold stamping die technology, and more specifically, to a cold stamping die wedge mechanism with angle adjustment function. Background Technology

[0002] The wedge mechanism is a core component in cold stamping dies that converts force into motion direction, and it is widely used in the processing of body panels, sheet metal parts, and other workpieces. Its core working principle is to use a sloping drive structure to convert the vertical driving force output by the press into a horizontal or inclined processing force, thereby meeting the complex process requirements of workpiece side trimming, side shaping, and multi-angle punching. It is a key mechanism to ensure the efficient operation of cold stamping and plays an irreplaceable role in industries such as automotive manufacturing and hardware processing.

[0003] Traditional cold stamping die wedge mechanisms have a fixed working angle. When faced with the processing requirements of different workpieces with inclined surfaces and diverse angles, special molds need to be customized, resulting in high mold manufacturing costs and long mold change cycles. Although some mechanisms can be adjusted by manually shimming, the operation is cumbersome and the precision is difficult to control, making it difficult to ensure the processing consistency of mass production. This can easily lead to part defects and further increase maintenance costs, making it difficult to meet the needs of modern manufacturing for efficient, precise, and low-cost processing.

The T-block 16 is slidably connected to the T-slot 17. A drive rod 18 is provided on one side of the wedge drive block 2. The drive rod 18 passes through one side of the base 1 and is fixedly connected to one side of the wedge drive block 2. A limit groove 4 is provided on one side of the base 1. The limit groove 4 is slidably connected to one side of the slider 3. A cavity 8 is provided on one side of the inside of the slider 3. A drive motor 9 is fixedly installed on one side of the inside of the cavity 8. A rotating shaft 10 is fixedly connected to the output end of the cavity 8. One end of the rotating shaft 10 is rotatably connected to the inner wall of the cavity 8. A worm gear 11 is fixedly connected to the outer wall of shaft 10. A rotating rod 12 is rotatably connected inside cavity 8. A worm wheel 13 is fixedly connected to the outer wall of rotating rod 12. The worm wheel 13 meshes with the worm gear 11. Fixed disks 5 are fixedly connected to both sides of slider 3. Limiting rails 6 are opened on the side of each fixed disk 5 near slider 3. Both sides of connecting frame 14 are fixedly connected to the outer wall of rotating rod 12. Connecting frame 14 extends through to the outside of slider 3. Limiting rod 15 is fixedly connected to one side of connecting frame 14. Limiting rod 15 is fixedly connected to one side of stamping head 7. The two ends of limiting rod 15 are slidably connected to the corresponding limiting rails 6.

[0029] The angle adjustment component enables precise adjustment of the processing angle of the stamping head 7 to adapt to different cold stamping processing requirements. The specific operation method is as follows: First, the adjustment parameters are set according to the angle requirements of the workpiece to be processed. Then, the drive motor 9, which is fixedly installed in the cavity 8 inside the slider 3, is started. The drive motor 9 is a servo motor, which has the advantages of controllable speed and fast response. It can accurately output the adjustment torque. The output end of the drive motor 9 drives the rotating shaft 10 to rotate smoothly around the bearing seat on the inner wall of the cavity 8 through a fixed connection. The rotating shaft 10 is made of 45 steel with heat treatment, which is rigid and not easy to deform. This causes the worm 11 fixed on the outer wall of the rotating shaft 10 to rotate synchronously. The worm 11 and the worm wheel 13 on the outer wall of the rotating rod 12 form a meshing transmission. By utilizing the inherent large reduction ratio characteristics of the worm wheel 13 and worm 11 mechanism, the high-speed rotation of the motor is converted into the low-speed, high-torque rotation of the rotating rod 12. At the same time, with its self-locking function, it is ensured that the stamping head 7 will not deviate in angle due to the stamping reaction force after it is adjusted to the correct position.

[0030] When the rotating rod 12 rotates, it drives the connecting frame 14, which is rigidly connected to it, to rotate synchronously. The limiting rod 15, which is welded and fixed on one side of the connecting frame 14, slides along the limiting track 6 inside the fixed plate 5. The limiting track 6 constrains the limiting rod 15, so that the stamping head 7 always moves along the preset arc trajectory, avoiding swaying during the adjustment process. During this process, the T-shaped block 16 on one side of the slider 3 forms a sliding fit with the T-shaped groove 17 of the wedge drive block 2, ensuring that the slider 3 moves with the wedge drive block 2 without jamming. The drive rod 18 drives the wedge drive block 2 to translate through the guide hole of the base 1. With the lateral constraint of the limiting slide groove 4 of the base 1 on the slider 3, the motion stability of the overall mechanism is further improved, and the stepless adjustment of the stamping head 7 is finally realized, thereby meeting the multi-angle stamping requirements of different workpieces.

[0031] The angle adjustment component enables stepless and precise adjustment of the processing angle of the stamping head 7 through the precise control of the drive motor 9 and the efficient transmission of the worm gear 11 of the worm wheel 13. Combined with the constraints of the limit rail 6 and the limit rod 15, the adjustment process is stable and free of wobbling. This allows for adaptation to the multi-angle stamping requirements of different workpieces without the need to change special molds, significantly reducing mold manufacturing costs and mold changeover time. Simultaneously, the self-locking property of the worm wheel 13 and worm gear 11 ensures the stability of the stamping head 7 angle after adjustment, avoiding deviation caused by stamping reaction force. Furthermore, the cooperation of the T-block 16, T-slot 17, and limit slide 4 improves the overall motion accuracy, enhancing the versatility and flexibility of the mechanism while ensuring consistency and reliability in batch processing. This effectively meets the requirements of modern cold stamping production for high efficiency, precision, and low cost.

[0032] Working principle: First, an external power source (such as a hydraulic cylinder or servo motor, installed on the outside of the base 1 and connected to the end of the drive rod 18 away from the wedge drive block 2) provides driving force, pushing the drive rod 18 to make linear reciprocating motion along the guide hole of the base 1, thereby driving the wedge drive block 2 to move synchronously.

[0033] When the wedge drive block 2 moves, the T-shaped groove 17 on one side of it forms a sliding engagement with the T-shaped block 16 of the slider 3, which converts the horizontal driving force into the slider 3 moving in an inclined or horizontal direction along the limiting groove 4 of the base 1. The specific direction is determined by the angle between the inclined surfaces of the T-shaped groove 17 and the T-shaped block 16, so that the slider 3 moves closer to or away from the workpiece to be processed.

[0034] Meanwhile, if the stamping angle needs to be adjusted, the drive motor 9 in the cavity 8 inside the slider 3 starts, and drives the worm 11 to rotate through the rotating shaft 10. By using the meshing transmission between the worm 11 and the worm wheel 13 on the rotating rod 12, the power is transmitted to the rotating rod 12, causing the connecting frame 14 to rotate with the rotating rod 12. The limiting rod 15 on one side of the connecting frame 14 slides along the limiting track 6 of the fixed plate 5, and finally drives the stamping head 7 to complete the angle adjustment.

[0035] When the slider 3 reaches the processing position under the drive of the wedge drive block 2, the adjusted stamping head 7 performs stamping processing on the workpiece under the synergistic action of the press. After processing is completed, the external power source pulls the drive rod 18 to reset, driving the wedge drive block 2 and the slider 3 back to the initial position, completing one stamping cycle.

[0036] All parts not covered in this device are the same as or can be implemented using existing technologies.

[0037] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
