A mold 18 is placed on the upper surface of the protective shell 2. The inner surface of the limiting shaft 4 is connected with a U-shaped lock 19. One side surface of the limiting block 15 is provided with a cylinder 20. One side surface of the cylinder 20 penetrates and connects with a connecting rod 21. One side surface of the connecting rod 21 is welded with a push plate 22. One side surface of the push plate 22 is attached with a rubber pad 23. Through the setting of the bending tooling for processing U-shaped buckles, the processing effect is better. First, fix the bottom plate 1, then install the protective shell 2, then remove the protective column 17, and then place the U-shaped lock 19 to be processed. Through the setting of the limiting shaft 4, the U-shaped lock 19 can be slidably placed when placed. Then, after the U-shaped lock 19 is completely placed, it can abut against the limiting block 15, so as to fix the U-shaped lock 19. Then, place the mold 18. When the mold 18 is just placed into the U-shaped lock 19, it will squeeze the placing shaft 7, and then the connecting shaft 6 can rotate in the rotation groove 5 through the setting of the placing shaft 7. When the connecting shaft 6 rotates, it can drive the first driving rod 9 to rotate in the sliding groove 14. When the first driving rod 9 rotates, it can pull the spring 12 to expand and contract. To ensure the stability of the spring 12, the other side of the spring 12 is connected with the second driving rod 11.

When the mold 18 is pressed down, it can drive the connecting shaft 6 to squeeze and process the U-shaped lock 19. After the equipment is used up, the protective column 17 can be placed, and then the cylinder 20 is started. Then, the air pressure inside the cylinder 20 can push the connecting rod 21 to expand and contract, and then the connecting rod 21 can drive the push plate 22 to move, and then the rubber pad 23 can be clamped. After the U-shaped lock 19 is placed, the U-shaped lock 19 can also be clamped through sleeving.Ensure the stability of the U-shaped lock 19 during use.

[0023] Furthermore, a limiting shaft 4 is connected through the inner surface of the protective shell 2. Through the setting of the protective shell 2, the tooling can be better protected.

Through the setting of the connecting shaft 6, the U-shaped lock 19 can be subjected to extrusion processing.

[0025] Furthermore, the inner wall size of the connecting shaft 6 matches the outer wall size of the placing shaft 7. Through the setting of the placing shaft 7, the connecting shaft 6 can rotate.

[0026] Furthermore, a spring 12 is connected to the side surfaces of the first driving rod 9 and the second driving rod 11 at the same time. The first driving rod 9 is connected through the sliding groove 14. Through the setting of the spring 12, the first driving rod 9 can automatically return to the initial position when it is time.

[0027] Furthermore, the first driving rod 9 slides in the sliding groove 14. Through the setting of the first driving rod 9, the connecting shaft 6 can be braked.

[0028] Furthermore, there are two groups of sliding grooves 14, and they are symmetrically distributed. Through the setting of the sliding grooves 14, the first driving rod 9 can be limited when it slides.

[0029] Furthermore, there are two groups of cylinders 20 and they are symmetrically distributed. Through the setting of the cylinders 20, the clamping stability is better.

[0030] Furthermore, one side surface of the protective column 17 is attached to the rubber pad 23. Through the setting of the protective column 17, the clamped components can be better protected.

[0031] Working principle: First, fix the bottom plate 1, then install the protective shell 2, then remove the protective column 17, and then place the U-shaped lock 19 to be processed. Through the setting of the limit shaft 4, the U-shaped lock 19 can be slidably placed when it is placed. Then, after the U-shaped lock 19 is completely placed, it can abut against the limit block 15, so as to fix the U-shaped lock 19. Then, place the mold 18. When the mold 18 is just placed into the U-shaped lock 19, it will squeeze the placement shaft 7. Then, through the setting of the placement shaft 7, the connecting shaft 6 can rotate in the rotation groove 5. When the connecting shaft 6 rotates, it can drive the first driving rod 9 to rotate in the sliding groove 14. When the first driving rod 9 rotates, it can pull the spring 12 to expand and contract. To ensure the stability of the spring 12, the other side of the spring 12 is connected to the second driving rod 11. In this way, when the first driving rod 9 is used through the spring 12, it can be pulled. After taking out the mold 18, the spring 12 can drive the first driving rod 9 back to the initial position. When the mold 18 is pressed down, it can drive the connecting shaft 6 to squeeze and process the U-shaped lock 19. After the equipment is used up, the protective column 17 can be placed, and then the air cylinder 20 is started. Then, the air pressure inside the air cylinder 20 can push the connecting rod 21 to expand and contract, and then the connecting rod 21 can drive the push plate 22 to move, and then the rubber pad 23 can be clamped. After the U-shaped lock 19 is placed, the U-shaped lock 19 can also be clamped through sleeving to ensure the stability of the U-shaped lock 19 during use.
