Abstract:
A bending die contact surface structure in which a fixed die and a rotary die are surface contacted to each other and together join to form a mounting surface for a workpiece, the mounting surface being divided by the contact surface, the rotary die is rotated rearward after press forming to cause the workpiece to be moved away from the rotary die,wherein the contact surface between the fixed die and the rotary die is formed in a flat plane, a rotary center point of the rotary die is set outside a line drawn from and perpendicular to one end of a linear line on the contact surface of the rotary die in a plane perpendicular to an axis of the rotary die, the rotary die is rotatable directly from the position of surface contact with the fixed die toward the other end of said linear line, the other end being on the contact surface.
