けたことを特徴とするプレス成形装置。 The workpiece is positioned on a lower die consisting of a punch and a collapse punch that can approach and move away from the punch in the horizontal direction, and the slide cam, which is driven in accordance with the lifting and lowering movement of the upper die, cooperates with the collapse punch. , in a press forming device that bends and forms a flange portion that becomes an inverse portion at the end of a workpiece,
A wedge-shaped auxiliary punch located between the punch and the collapse punch and having an upper surface aligned with the work supporting surfaces of the punch and the collapse punch is elastically supported by the collapse punch so as to be movable up and down, and is driven to move up and down by an actuator. A press forming apparatus characterized in that the collapse punch is provided with a stopper that restrains the punch, the collapse punch, and the auxiliary punch so that they cannot move relative to each other.
