The device can be placed on an external horizontal plane through the bottom plate 15. By utilizing the fixing holes on the bottom plate 15 and the use of external bolts, the bottom plate 15 can be fixed to the external horizontal plane to complete the installation of the device and enhance the stability of the bottom of the device.

[0029] The top of the plurality of support columns 10 are fixedly connected to the same connecting plate 11, and the plurality of support columns 10 are symmetrical about the vertical center line of the connecting plate 11. The connecting plate 11 is provided with a plurality of threaded holes, and the plurality of threaded holes are evenly distributed in a ring shape about the vertical center line of the connecting plate 11. The slide 4 is symmetrical about the vertical center line of the upper module 3, and the outer size of the lower module 1 is consistent with the outer size of the upper module 3. The plurality of telescopic rods 2 are symmetrical about the vertical center line of the upper module 3. The top center of the lower module 1 is fixedly connected with a pressure block 9. The device can be connected to an external cylinder through the connecting plate 11. With the use of the support columns 10, the external cylinder controls the upper module 3 to move up and down, and uses the external cylinder to move the upper module 3 downward. With the use of the lower module 1 and the pressure block 9, the automotive parts on the cushion frame 12 can be stamped.

[0030] In this embodiment, a cushion frame 12 is provided on the outside of the pressure block 9, and a through opening is opened in the center of the cushion frame 12 for the pressure block 9 to pass through. The four corners of the cushion frame 12 are fixedly connected with telescopic columns 13, and the bottom end of the telescopic column 13 is fixedly connected to the top of the lower module 1. A spring 14 is provided on the outside of the telescopic column 13, and the telescopic column 13 is symmetrical about the vertical center line of the cushion frame 12. The central axis of the telescopic column 13 coincides with the central axis of the spring 14, and the inner size of the spring 14 matches the outer size of the telescopic column 13. The cushion frame 12 can be used to prevent parts that need to be stamped. Through the elastic force of the spring 14 and the use of the telescopic column 13, the automobile parts can be lifted and transported away after the stamping is completed, which facilitates the loading and unloading of the device and improves the efficiency of stamping.

[0031] The chute 4 is provided with a locking ring 6 on the outer side of the top end of the connecting tube 5 and a hanging rod 7 is connected to the inside of the connecting tube 5 in a rotating manner, and the hanging rod 7 passes through the connecting tube 5. A guide roller 8 is inserted at the bottom of the hanging rod 7. A telescopic structure is formed between the guide roller 8 and the hanging rod 7. By sliding the connecting tube 5 in the chute 4, the distance between the two guide rollers 8 on the same side can be adjusted. By tightening the locking ring 6, the connecting tube 5 can be fixed in the chute 4. The two guide rollers 8 on the same side can be used to limit the automobile parts to prevent deviation during feeding and ensure the quality of stamping. At the same time, the hanging rod 7 is rotatably connected to the connecting tube 5, so that the guide roller 8 plays a guiding role when the automobile parts are transported.

[0032] In this embodiment, slots 16 opposite to the slide groove 4 are provided on both sides of the lower module 1. The width of the slots 16 is greater than the diameter of the guide roller 8. The telescopic setting of the hanging rod 7 and the guide roller 8, combined with the use of the slots 16, makes it difficult for the guide roller 8 to collide with the lower module 1 during stamping.

[0033] Working principle: When using this device, first, the base plate 15 can be used to place the device on the external horizontal plane. By using the fixing holes on the base plate 15 and in conjunction with external bolts, the base plate 15 can be fixed to the external horizontal plane to complete the installation of the device and enhance the stability of the bottom of the device. The pad frame 12 can be used to prevent parts that need to be stamped. The connecting plate 11 can be used to connect the device to the external cylinder and in conjunction with the support column 10, so that the external cylinder controls the upper module 3 to move up and down. The external cylinder is used to move the upper module 3 downward and in conjunction with the lower module 1 and the pressure block 9, the automotive parts on the pad frame 12 can be stamped. By using the elastic force of the spring 14 and in conjunction with the telescopic column 13, the automotive parts can be lifted and transported away after the stamping is completed, which facilitates the loading and unloading of the device and improves the efficiency of stamping.

[0034] By sliding the connecting tube 5 in the slide 4, the distance between the two guide rollers 8 on the same side can be adjusted, and by tightening the locking ring 6, the connecting tube 5 can be fixed in the slide 4. The two guide rollers 8 on the same side can limit the automobile parts and prevent them from being offset during feeding, thereby ensuring the quality of stamping. At the same time, the hanging rod 7 is rotatably connected to the connecting tube 5, so that the guide roller 8 plays a guiding role when transporting automobile parts, and the telescopic setting of the hanging rod 7 and the guide roller 8, combined with the use of the slot 16, makes it difficult for the guide roller 8 to collide with the lower module 1 during stamping.
