置。It consists of a lower die punch, a lower die blank holder, an upper die, a cushion device, and an elastic member. The upper die is arranged to be movable up and down, and has a blank holder surface formed on the upper surface, and a concave surface for forming the workpiece corresponding to the lower die punch is formed on the lower center surface of the upper die. A blank holder surface corresponding to the blank holder surface of the lower mold is formed, and the cushion device is biased by an air cylinder device so that the lower mold blank holder is constantly lifted to a raised position with respect to the lower mold punch. The elastic member is disposed at the lower part of the lower mold blank holder so as to begin to be compressed when the lower mold blank holder is lowered by a predetermined amount, and increases the clamping force of the blank holder in the middle of the lowering stroke of the upper mold. A press device characterized in that it is designed to
