たことを特徴とするプレス成形装置。 Above the lower holder to which a lower mold having a die is fixed, there is an upper mold having a punch for drawing the molded material in cooperation with the die, and a blank holder for clamping the molded material between the die and the lower holder. In a press forming apparatus that is installed so as to be able to approach and separate from the lower die, one end of a first arm member rotatably provided on the lower holder is connected to a button die incorporated in the punch. A piercing punch that performs hole-drilling by working together is attached, and a slide cam provided with a holding part for holding the other end of the first arm member is attached so as to be slidable on the lower holder, and the slide cam is moved while moving together with the punch. A drive cam for driving a cam is integrally fixed to the punch, and is contracted by the first arm member and the drive cam to accumulate elastic force when the upper mold and the lower mold move relatively close to each other. , an elastic means configured to rotate the first arm member by an elastic force when the first arm member is detached from the holding portion of the slide cam to perform drilling with the piercing punch; A press molding device, characterized in that it is installed between the drive cam and the drive cam.
