Continuous die for anti-explosion hoop

The invention relates to a continuous die for an anti-explosion hoop. The die comprises an upper die part and a lower die part which are matched with each other; the upper die part comprises an upperdie plate and punch heads and falling convex and concave dies which are fixedly arranged in the upper die plate, and the punch heads are sleeved with the falling convex and concave dies; the lower diepart comprises a lower die plate and falling inserts and stretching convex and concave dies which are fixedly arranged in the lower die plate, and the positions of the stretching convex and concave dies correspond to those of the falling convex and concave dies of the upper die part; the die is further provided with a material returning device, the upper die part is provided with a beating rod material returning mechanism and a discharging plate, and the lower die part is provided with a bottom die material returning device and a lower material returning block. According to the die, two stations are arranged in parallel in a staggered mode, the width of produced strip materials is small, and the material utilization rate is increased; when the die is used, the die is installed on a punching machine tool, a material belt is automatically fed through a feeding machine, the die moves downwards to enable the falling convex and concave dies, the punch heads, the inserts and the stretchingconvex and concave dies to achieve interaction to conduct cutting, falling, stretching forming and punching on the material belt, production of two workpieces can be simultaneously completed through one time of punching, action is simple, safe and convenient to achieve, and the workpiece output efficiency is high.
