The third punch 7, the fourth punch 8, and the cutting punch 9 sequentially contact the corresponding slots on the lower die base 1. After the metal strip is conveyed into place through the strip passage, the first punch 5 enters the first slot 10 to perform preliminary stamping on the strip. Then, the second punch 6 and the third punch 7 work simultaneously to complete the stamping of a specific shape. The fourth punch 8 then continues the stamping process to achieve the arc bending of the metal clip. Finally, the cutting punch 9 cuts off the processed metal clip from the strip. Each punch and slot is precisely aligned, and with the precise guidance of the upper die base 3 by the limiting post 2, the punch position is ensured to be accurate during the stamping process, improving the dimensional and shape accuracy of the metal clip and ensuring product quality. The multi-station continuous stamping design allows multiple stamping processes to be completed in one stroke, effectively reducing material waste during idle strokes and lowering the scrap rate. Compared with common single-station stamping equipment, it greatly shortens the production cycle, improves production efficiency, and meets the delivery needs of large-scale orders.

[0022] In this embodiment, an ejector spring 15 is fixedly connected to the inner wall of the fourth punch groove 13. A movable inner cavity 18 is also provided inside the fourth punch groove 13. An ejector mechanism is installed inside the movable inner cavity 18, including a slide groove 19, a slider 20, a top plate 21, and an electric push rod 22. The inner wall of the movable inner cavity 18 has a slide groove 19, and a slider 20 is slidably connected to the inner wall of the slide groove 19. The top plate 21 is fixedly connected to the side wall of the slider 20. The electric push rod 22 is fixedly connected to the inner wall of the movable inner cavity 18, and the movable end of the electric push rod 22 is fixedly connected to the lower surface of the top plate 21. Two sets of baffles 16 are fixedly connected to the surface of the lower die base 1, forming a material passage cavity between the two sets of baffles 16. A wedge-shaped discharge port 17 is provided on the surface of the lower die base 1. The metal clips are stamped... After completion, the electric push rod 22 is activated, pushing the top plate 21 upward. The top plate 21 rises smoothly through the sliding of the slider 20 in the slide groove 19, ejecting the stamped metal clip from the fourth punch groove 13. With the help of the ejection spring 15, a double-acting ejection system is realized, ensuring the success rate of workpiece demolding, reducing manual intervention, and the baffle 16 prevents the material from shifting. After the workpiece is demolded, due to the continuous movement of the material, the material pushes the stamped metal clip towards the discharge port 17, and the stamped metal clip is discharged through the wedge-shaped discharge port 17. There is no need for manual removal of the finished material from the mold groove, ensuring the personal safety of the workers, reducing the labor intensity of the workers, improving the degree of automation and production continuity, that is, improving production efficiency, high work efficiency, and easy to use.

[0023] An external power drive mechanism drives the upper die base 3 to move downwards along the limiting post 2. The first punch 5, second punch 6, third punch 7, fourth punch 8, and cutting punch 9 on the upper die base 3 sequentially contact the corresponding slots on the lower die base 1. When the metal strip is conveyed into place through the strip passage cavity, the first punch 5 enters the first slot 10 to perform preliminary stamping of the strip. Then, the second punch 6 and the third punch 7 work simultaneously to complete the stamping of a specific shape. Finally, the fourth punch 8 continues the stamping process, achieving… The metal clip is bent by the arc, and finally the cutting punch 9 cuts off the processed metal clip from the strip. After the metal clip is stamped, the electric push rod 22 is started, pushing the top plate 21 to move upward. The top plate 21 rises smoothly through the sliding of the slider 20 in the slide groove 19, and pushes the stamped metal clip out from the fourth punch groove 13. Due to the continuous movement of the strip, the strip pushes the stamped metal clip to the discharge port 17, and the stamped metal clip is discharged through the wedge-shaped discharge port 17.

[0024] Each punch in this application precisely corresponds to the slot, and with the precise guidance of the limit post 2 to the upper die base 3, the punch position is accurate during the stamping process, improving the dimensional and shape accuracy of the metal clips and ensuring product quality. The multi-station continuous stamping design allows multiple stamping processes to be completed in one stroke, effectively reducing material waste during idle strokes and lowering the scrap rate. Compared with common single-station stamping equipment, it greatly shortens the production cycle, improves production efficiency, and meets the delivery needs of large-scale orders. The ejector mechanism, together with the ejector spring 15, realizes a double-acting ejector system, ensuring the success rate of workpiece demolding and reducing manual intervention. The baffle 16 prevents the strip from shifting. After the workpiece is demolded, due to the continuous movement of the strip, the strip pushes the stamped metal clips towards the discharge port 17, and the stamped metal clips are discharged through the wedge-shaped discharge port 17. There is no need for manual removal of the finished material from the die slot, ensuring the personal safety of the workers, reducing the labor intensity of the workers, improving the degree of automation and production continuity, that is, improving production efficiency, high work efficiency, and easy to use.
