とするフランジ加工用プレス成形装置。[Claims for Utility Model Registration] An inverse flange that forms an inverse shape with respect to the workpiece removal direction at the peripheral edge of a panel-shaped workpiece with an opening punched in the center by cooperation between a lower die and an upper die. At the same time, a flange part is bent and formed on the peripheral edge of the opening, and after the press forming is completed, a part of the lower die is moved horizontally to avoid the inverse shape and move upwards of the lower die. In a press molding device that allows the workpiece to be taken out, the lower die is elastically supported on the lower holder so as to be able to move up and down, and a cushion punch is used to bend and form the flange portion in cooperation with a sectional die on the upper die side. and,
Mounted horizontally on the cushion punch,
A collapse punch works with the slide cam on the upper mold side to bend and form the inverse flange part, and a collapse punch stands upright from the lower holder and is located between the cushion punch and the collapse punch during flange processing. While being squeezed by the punch and regulating the position of the collapse punch to the normal processing position,
1. A press-forming device for flange processing, comprising a back-up key that allows horizontal movement of a collapse punch in a direction to avoid an inverse flange portion when the upper die is raised.
