Claims

[Claims for Utility Model Registration] A bending blade that bends the edge of a workpiece upward or downward by moving up and down relative to the workpiece held between a pad and a punch;
A press mold including a cam bending blade that laterally presses and bends a portion of the edge of the workpiece that is closer to the edge than the portion bent by the bending blade, wherein the bending blade is configured to bend the cam bending blade. The blades are supported in the vertical direction via an elastic body so as to protrude and retract with respect to the stroke area, and between these bending blades and the cam bending blade, the bending blade is moved by the advancement of the cam bending blade. A press mold characterized by being provided with a cam mechanism that moves in and out of the stroke area of the cam bending blade and pushes the work back to a position where the work is clamped in the lateral direction.
