Abstract

PURPOSE: To contrive to secure the bending strength and bending rigidity of the die against the work of extensively various shape, by holding the pad base of the specified shape in the cavity of the main body of upper die, and also, by installing suitable number of guide pins for transmitting the press force of the pad base to the product pad thrusted against the work.
CONSTITUTION: When the main body 3 of upper die goes down, and the bottom face of the product pad 9 is thrusted against the work W, the pad base 4 is stopped through the guide pin 12; hereby, the spring 6 is compressed, and its spring action thrusts the work against the punch 2. Next, the cutting edge 10 attached to the ring 8 of upper die and the blanking punch 15 stick out, and the press forming work is executed. The outer shape of the pad base, being held in the cavity of the main body of upper die, is formed equal to or larger than the outer shape of the largest work; accordingly, by adjusting the position of the guide pin correspondingly to the size of the work, the overhang of the load can be reduced.
