[0033] Referring to Figure 3 , the linkage structure 10 comprises a connecting frame 11 fixedly connected to the output end of the hydraulic cylinder 4, the bottom of the connecting frame 11 is fixedly connected with extension plates 12 on both sides, one side of the extension plates 12 away from the connecting frame 11 extends to the outside of the swing rods 9 through the back of the profiling base 3, the extension plates 12 can extrude the swing rods 9 to swing by carrying the extension plates 12 through the connecting frame 11 during the operation of the hydraulic cylinder 4, one end of the swing rods 9 away from the shaft rods 7 is fixedly connected with maintaining plates 13, the extension plates 12 can be slidably connected with the swing rods 9 and the maintaining plates 13 respectively, the extension plates 12 are out of contact with the swing rods 9 and keep horizontal sliding with the maintaining plates 13 during the continuous descending process.

[0034] As a technical optimization of this utility model, the connecting frame 11, the extension plate 12, and the sliding connection with the swing rod 9 and the holding plate 13 enable the hydraulic cylinder 4 to use the connecting frame 11 and the extension plate 12 to squeeze the swing rod 9 to swing during operation, thereby driving the pressure plate 8 to fix the bumper. When the extension plate 12 continues to descend, it disengages from the swing rod 9 and slides horizontally with the holding plate 13, thereby achieving precise control of the stamping process.

[0035] refer to Figure 3 The side of the extension plate 12 away from the connecting frame 11 is movably connected to a roller 14 via a pin, and the outer surface of the roller 14 is in contact with the surface of the rocker arm 9.

[0036] As a technical optimization of this utility model, the roller 14 movably connected to the side of the extension plate 12 away from the connecting frame 11, and the contact between the roller 14 and the surface of the swing arm 9, reduce the friction between the extension plate 12 and the swing arm 9, so that the swing arm 9 can swing more smoothly when squeezed, reduce friction loss during equipment operation, and improve the durability and stability of the equipment.

[0037] refer to Figure 3 Limiting plates 15 are fixedly connected to both sides of the front of the frame 1. A spring plate 16 is fixedly connected to the back of the limiting plate 15. The side of the spring plate 16 away from the limiting plate 15 contacts the front of the swing rod 9. The spring plate 16 is elastic.

[0038] As a technical optimization of this utility model, through the design of the limiting plate 15 and the spring plate 16 on the front of the frame 1, and the front contact between the spring plate 16 and the swing rod 9, the spring plate 16 can position and support the swing rod 9 when it swings to a certain position, thereby ensuring the stability of the bumper during the punching process.

[0039] refer to Figure 3 A bending plate 17 is fixedly connected to the bottom of the maintaining plate 13. During the continuous descent, the extension plate 12 disengages from the maintaining plate 13 and comes into contact with the bending plate 17, generating vibration.

[0040] As a technical optimization of this utility model, by maintaining the bending plate 17 fixedly connected to the bottom of the plate 13, vibration can be generated by the contact between the bending plate 17 and the extension plate 12 after the punching operation is completed, thereby helping the bumper and scrap to fall off the equipment.

[0041] refer to Figure 2 Angle plates 18 are fixedly connected to both sides of the bottom of the connecting frame 11, and the back of the angle plates 18 is fixedly connected to the surface of the extension plate 12.

[0042] As a technical optimization of this utility model, the corner plates 18 fixedly connected to the bottom two sides of the connecting frame 11, and the fixed connection between the corner plates 18 and the surface of the extension plate 12, enhance the connection strength between the connecting frame 11 and the extension plate 12, making the entire linkage structure 10 more stable and reliable.

[0043] The working principle and usage process of this utility model are as follows: It mainly includes a frame 1, a stamping assembly 2, a contouring base 3, and a series of linkage structures 10. First, the bumper is placed on top of the contouring base 3 to ensure accurate and stable positioning. When the stamping assembly 2 starts working, the hydraulic cylinder 4, as the power source, begins to operate. The output end of the hydraulic cylinder 4 is fixedly connected to the stamping part 5, while the other end of the hydraulic cylinder 4 is connected to the extension plate 12 through the connecting frame 11. As the piston rod of the hydraulic cylinder 4 extends, the stamping part 5 begins to move downward, preparing to punch holes in the bumper. At the same time, the connecting frame 11 moves together with the output end of the hydraulic cylinder 4. The extension plate 12 at the bottom of the connecting frame 11 extends to the outside of the swing arm 9 through the back of the contouring base 3. When the extension plate 12 descends with the connecting frame 11, it begins to squeeze the swing arm 9. After being squeezed, the swing arm 9 is driven by the shaft 7. The dynamic pressure plate 8 swings on top of the contour base 3. This swinging motion is to initially fix and position the bumper before stamping, preventing it from moving during the punching process. As the extension plate 12 continues to descend, it first contacts the swing arm 9 and squeezes it to swing. Then, when the extension plate 12 continues to descend and disengages from the swing arm 9, it slides horizontally with the holding plate 13. Its function is to ensure that the swing arm 9 can remain stable after swinging to a certain position and no longer swing. At this time, the hydraulic cylinder 4 carries the stamping part 5 to continue to descend and complete the stamping. In addition, the bottom of the holding plate 13 is also fixedly connected to the bending plate 17. When the extension plate 12 disengages from the holding plate 13 during the continuous descent, it contacts the bending plate 17 and generates vibration. The vibration force is transmitted to the contour base 3, which helps to discharge the internal stamping waste and prevents waste accumulation.

[0044] In summary, this punching equipment for automotive bumper processing, through the configuration of a hydraulic cylinder 4 fixedly connected inside the stamping assembly 2, a connecting block 6 on the front of the frame 1, a shaft 7, a pressure plate 8, a swing arm 9, and a linkage structure 10 on the surface of the stamping assembly 2, enables the equipment to fix the bumper in linkage during the stamping process, thereby improving the stability and accuracy of the punching operation. The structural design achieves automated fixing and punching operations, improving production efficiency and product quality.
