A punching and chamfering synchronous stamping die comprises an upper die base, a stripper plate and a lower die base;

a limit bolt is arranged in the upper die base, and a male die fixing plate, a punching chamfering male die and a material pressing spring are connected below the upper die base; the stripper is connected with the upper die base through a limiting bolt penetrating through the male die fixing plate, and realizes the reciprocating motion of unloading and pressing through the compression force of a pressing spring; the punching chamfering male die is fixed on the male die fixing plate through a limit fit clearance;

A punching concave template is arranged on the lower die base;

guide posts are arranged among the upper die base, the male die fixing plate, the stripper plate, the punching female die plate and the lower die base, and the upper die base, the male die fixing plate and the stripper plate slide up and down along the guide posts.

Furthermore, the tail section of the limiting bolt is installed in the upper die base through a limiting ring, the middle section of the limiting bolt is sleeved in the male die fixing plate and penetrates through the male die fixing plate, and the top section of the limiting bolt is in threaded connection with the stripper plate.

Furthermore, the upper die base is fixed on the upper table surface of the punching machine during punching.

Furthermore, during punching, the stripper plate is attached to the punching concave die plate and the product, the material pressing and positioning effects are achieved on the product, then the punch press continues to move downwards, the material pressing spring starts to compress, the stripper plate is attached to the male die fixing plate, the punching chamfering male die penetrates through a female die knife edge on the punching concave die plate, and the product punching chamfering is finished.

Compared with the prior art, the utility model has the beneficial effects that: the stripper plate is arranged between the upper die holder and the lower die holder, the punching chamfering male die, the material pressing spring and the limiting bolt are arranged below the upper die holder, the punching concave die plate is arranged on the lower die holder, a product is placed on the punching concave die plate, and the upper die is used for punching downwards, so that synchronous punching of punching and chamfering is realized.

Detailed Description

The technical scheme of the utility model is further explained in detail by combining the drawings in the specification.

As shown in fig. 1, 2 and 3, a punching and chamfering die structure comprises an upper die base 5, a discharging plate 7 and a lower die base 9 which are sequentially connected from top to bottom, guide posts 1 with guiding functions are further arranged between the upper die base 5, a punch fixing plate 6, the discharging plate 7, a punching concave die plate 8 and the lower die base 9, the upper die base 5, the punch fixing plate 6 and the discharging plate 7 slide up and down along the guide posts 1, a limiting bolt 2, a punch fixing plate 6, a punching chamfering convex die 3 and a material pressing spring 4 are further connected below the upper die base 5, the material pressing spring 4 acts on the upper die base 5 and the discharging plate 7, the punching chamfering convex die 3 is fixed on the punch fixing plate 6 through a limit fit clearance, the lower die base 9 is provided with the punching concave die plate 8, a product 10 is placed on the punching concave die plate 8, and one-time punching is completed by moving the upper die to be completely closed Simple structure, easy manufacture and low cost.

The use process of the die is as follows:

A. during punching, the upper die base 5 is fixed on the upper table surface of a punching machine, the punching chamfering male die 3 is fixed on a male die fixing plate 6 through a limit fit clearance and integrally fixed on the upper die base 5, the stripper 7 is connected on the upper die base 5 through a limiting bolt 2, reciprocating motion of unloading and pressing is realized through the compression force of a pressing spring 4, and the stripper is connected with an upper die of a forming die.
