As preferably, described block is the U-shaped of handstand, die socket upper side is provided with the U-shaped groove that side direction rear side runs through in the past, the die socket upper side left and right sides is respectively equipped with chute, left half die and right half die are separately positioned in the chute of both sides, the below of chute is provided with the passage parallel with chute, elastic connecting device comprises spring, block alignment pin and die alignment pin, block alignment pin is vertically fixedly connected in the U-shaped of block, die alignment pin is vertically fixedly connected on the downside of left half die and right half die, the lower end of die alignment pin is positioned at passage, the lower end of two alignment pins is fixedly connected with spring.
As preferably, the below connection backing plate of described upper bolster, the below of backing plate is connected and fixed plate, and punch is fixedly connected on fixed head.
As preferably, described location structure is location-plate, and location-plate is fixedly connected on the upper side of left half die and right half die.
As preferably, the top of described upper bolster connects die shank.
The beneficial effects of the utility model are, product is difficult for producing resilience, and product quality is high, without subsequent handling finishing, have reduced production hour, have reduced production cost, simple in structure, easy to operate.
