Through the arrangement of the lower die base 1, the limiting column 2, the telescopic rod 3 and the upper die base 4, during use, the upper die base 4 first punches the position of the lower die base 1. During the stamping process, when the upper die base 4 reaches the position of the limiting column 2, it will not be able to continue to stamp the lower die base 1. Secondly, the telescopic rod 3 has a certain buffering effect during stamping, in that the limiting column 2 cooperates with each other to form a protective effect on the stamped workpiece, thereby avoiding excessive stamping and damaging the workpiece.

[0023] Furthermore, the telescopic rods 3 are symmetrically arranged on the central axis of the upper die base 4, and two groups of limit columns 2 are provided. Through the arrangement of the telescopic rods 3 and the limit columns 2, during the stamping process of the upper die base 4, the telescopic rods 3 on both sides can buffer the pressure of the stamping process to a certain extent, and the stamping distance of the upper die base 4 is limited by the limit columns 2, which can prevent excessive stamping from damaging the workpiece.

During stamping, the upper die pad 6 can maintain the stability and accuracy of the punch 7.

[0025] Furthermore, the positioning column 5 is symmetrically arranged with respect to the central axis of the upper die pad 6 , and the positioning column 5 penetrates through the upper die pad 6 and the punch 7 to be connected. Through the arrangement of the positioning column 5 , the connection between the upper die pad 6 and the punch 7 is more stable.

Through the lower die base 1, the die 9, the telescopic slot 10, the spring 11, the sliding block 12, the card block 13, the ejecting block 14, the first sliding slot 15, the second sliding slot 16, the stamping part 17 and the card slot 18, during use, the ejecting block 14 is first placed in the slot on the die 9, and then the ejecting block 14 is connected to the lower die base 1, and the sliding block 12 is pushed to slide to the top in the first sliding slot 15 by the spring 11 in the die 9, so that the card block 13 slides out of the second sliding slot 16 and is stuck in the card slot 18 on the stamping part 17.

[0027] Furthermore, the sliding block 12 is slidably connected to the first sliding groove 15, and the sliding block 12 and the spring 11 form a telescopic structure. Through the setting of the sliding block 12, under the action of the sliding block 12, the clamping block 13 can better limit the stamping part 17 during the stamping process.

[0028] Furthermore, the block 13 and the slot 18 are engaged and connected, and the block 13 and the second sliding slot 16 are slidably connected. Through the setting of the block 13, the limiting of the stamping part 17 is more stable and will not shake due to the gap, thereby ensuring accuracy.

Through the setting of the sliding block 12, the sliding between the first sliding groove 15 of the sliding block 12 and the telescopic groove 10 is smoother and more stable.

[0030] Working principle: First, during the stamping process, the upper die base 4 stamps toward the lower die base 1. When stamping, the upper die base 4 will not be able to continue stamping the lower die base 1 when it reaches the position of the limit column 2. Secondly, the telescopic rod 3 has a certain buffering effect during stamping. In cooperation with the limit column 2, it can protect the stamped workpiece and avoid damage to the workpiece by excessive stamping. In addition, the positioning column 5 is used to penetrate the punch 7 and the upper die pad 6, and then they are fixed to the upper die base 4. The upper die pad 6 can maintain the stability and accuracy of the punch 7, and the top block 14 is placed in the groove on the die 9, and then the spring 11 in the die 9 pushes the sliding block 12 to slide to the top in the first sliding groove 15, so that the card block 13 slides out of the second sliding groove 16, and finally the stamping part 17 is placed on the top block 14, and the card slot 18 on the stamping part 17 is stuck on the card block 13.
