The punching driving mechanism 4 is connected with the punching tool table 2 to drive the punching tool table 2 to make a punching action. The adjusting platform 3 drives the punching base 1 to move along the X-axis direction and the Y-axis direction to adjust the punching position.

[0044] In the utility model, the specific position of the punching can be adjusted through the adjusting platform 3, so that the punching position is matched with the feeding position. Therefore, when the external automatic feeding device is used, the end of the wire can be fed to the punching position, and the subsequent automatic feeding and punching are facilitated. The punching driving mechanism 4 automatically drives the punching tool table 2 to make a lifting motion or a punching motion, so that the punching tool table 2 moves towards the punching base 1, and the tool 22 on the punching tool table 2 moves towards the tool groove 121 to punch the end of the wire moving above the tool groove 121. Through the adjusting platform 3, the punching position is aligned with the feeding position of the external feeding device, and the punching is automatically driven by using the punching driving mechanism 4. Therefore, the rapid automatic punching of the end of the wire is realized, and the processing efficiency is good and the production cost is low.

[0045] Further, as shown in Figure 1 , Figure 2 , the wire punching device further comprises a lifting guide mechanism 5 arranged on the punching base 1.
