[0022] The present invention will now be further described with reference to the accompanying drawings.

[0023] See also Figures 1-6 A continuous die device for chain plate stamping includes an upper die base 1, a lower die base 2, a die 3 and a punch 4. The die 3 is connected to the upper surface of the lower die base 2, and the punch 4 is connected to the lower surface of the upper die base 1. The inner side of the die 3 is provided with a plurality of grooves 20 of different shapes. The lower surface of the punch 4 is connected with a plurality of protrusions 21 of different shapes. The grooves 20 are adapted to the punch 4. The protrusions 21 of different shapes pass through the grooves 20. The plate is stamped by the protrusions 21 of different shapes to shape the plate into the required shape. For products, the chain plate stamping is roughly divided into three links. The first is to punch out the center hole, which is used for positioning in subsequent stamping links. In the second and third links, through holes and teeth are punched out with the center hole as the center. The lower surface of the upper die base 1 is connected with a guide sleeve 22, and the upper surface of the lower die base 2 is connected with a guide column 23. The outer surface of the guide column 23 is slidably connected to the inner wall of the guide sleeve 22, and the guide column 23 provides direction guidance for the guide sleeve 22. The upper die base 1 is slidably connected to the guide column 23 through the guide sleeve 22 to guide the moving direction of the upper die base 1.

[0024] The inner side of the punch 4 is connected to a sleeve 5, and a plurality of slideways 6 are provided on the inner side of the sleeve 5. The inner walls of the plurality of slideways 6 are slidably connected to a slide seat 7, and the slide seat 7 is kept stable in the moving position by the slideway 6. The slide seat 7 is located at one end inside the sleeve 5 and has an inclined angle. A spring 8 is provided above the plurality of slide seats 7, and the spring 8 is sleeved on the outside of the guide rod 17. One end of the spring 8 is connected to one side of the base 16, and the other end of the spring 8 is connected to the inner wall of the sleeve 5. The spring 8 provides elastic support force for the slide seat 7, and the spring 8 is compressed after the slide seat 7 moves to a different position, and the compressed spring 8 provides power for the slide seat 7 to reset.

[0025] The inner walls of the plurality of slides 7 are provided with a slide groove 9, and the inner wall of the slide groove 9 is slidably connected with a top block 15, and the slide groove 9 provides the top block 15 with space for movement. After the punch 4 drives the sleeve 5 to move downward, the top block 15 contacts the center hole inside the chain plate, but the sleeve 5 will also move downward a distance. After the top block 15 contacts the center hole, it will expand outward, but the top block 15 is blocked by the die 3 and cannot continue to move. While the top block 15 expands outward, the position between it and the sleeve 5 is compensated by the slide groove 9. The difference is that a spring 2 11 is provided inside the slide groove 9, and a guide rod 2 18 is connected to the inner wall of the slide groove 9. The outer surface of the guide rod 2 18 is slidably connected to the inner wall of the top block 15. The spring 2 11 is sleeved on the outside of the guide rod 2 18. One end of the spring 2 11 is connected to the inner top wall of the slide groove 9, and the other end of the spring 2 11 is connected to one side of the top block 15. The spring 2 11 provides elastic supporting force for the top block 15. After the top block 15 moves, the spring 2 11 is compressed, and the compressed spring 2 11 provides power for the top block 15 to reset.

[0026] The inner wall of the sliding sleeve 5 is slidably connected with a conical push block 12, and the outer surface of the conical push block 12 is slidably connected to one end of the sliding seat 7. A spring three 13 is provided above the conical push block 12, and the end of the conical push block 12 located outside the sliding sleeve 5 is connected with a positioning block 10. A positioning groove 14 is provided on the inner side of the die 3, and the positioning groove 14 is adapted to the positioning block 10. The stability of the positioning block 10 is maintained by the positioning groove 14. After the positioning block 10 contacts the positioning groove 14, it cannot continue to move downward. The positioning block 10 pushes the conical push block 12 to move upward. The conical push block 12 pushes the slide 7 to move outward through the inclination angle. By moving the slide 7 outward, the top block 15 is driven to expand outward. After the top block 15 expands, it contacts the center hole of the chain disk, firmly fixing the raw material plate at the position where the sliding sleeve 5 is the center point.

[0027] The number of the multiple slides 6 is four, and the four slides 6 are arranged in a circular array. The upper surface of the slide 7 is connected to the base 16, and one side of the base 16 is connected to the guide rod 17. The outer surface of the guide rod 17 is slidably connected to the inner wall of the sleeve 5. The slide 7 receives the telescopic power of the spring 8 through the base 16. The four slides 7 correspond to the same number of slides 6, and the top block 15 is driven by the four slides 7 to provide support in four directions.

[0028] The inner top wall of the sliding sleeve 5 is connected to a support column 19, one end of the support column 19 is slidably connected to the inner wall of the conical push block 12, and a spring three 13 is sleeved on the outside of the support column 19, one end of the spring three 13 is connected to the inner top wall of the sliding sleeve 5, and the other end of the spring three 13 is connected to the upper surface of the conical push block 12. The spring three 13 provides elastic supporting force for the conical push block 12, and the spring three 13 is compressed after the conical push block 12 moves its position. The compressed spring three 13 provides power for the conical push block 12 to reset.

[0029] The guide rod 17, the guide rod 2, the guide rod 18, and the support column 19 support the spring 18, the spring 2, the spring 11, and the spring 3, and the spring 18, the spring 2, the spring 11, and the spring 3, and the support column 19 support the spring 18, the spring 2, the spring 11, and the spring 3, so as to improve the stability of the spring 18, the spring 2, the spring 11, and the spring 3 during elastic contraction.

[0030] When the utility model is in use: first, the raw material sheet is fed into the interior of the die 3, then the first step of stamping is completed in the die 3, and then the raw material sheet continues to move to a set distance. After the center hole is aligned with the sliding sleeve 5, the upper die seat 1 drives the sliding sleeve 5 to move downward through the punch 4, and then the sliding sleeve 5 drives the top block 15 downward to enter the interior of the center hole, and the positioning block 10 contacts the positioning groove 14. At the same time, the positioning block 10 pushes the conical push block 12 to move upward. When the conical push block 12 moves, it pushes the slide 7 to move to the outside of the sliding sleeve 5. Then, the top block 15 expands to the outside around and contacts the center hole under the push of the slide 7. The punch 4 outside the sliding sleeve 5 punches the outside of the raw material sheet with the center hole as the center of the circle.
