Claims

[Scope of utility model registration request]

The upper die is provided with a pad that presses and holds a work and a drive cam having a cam surface, and the lower die is provided with a passive cam that slides on the cam surface and moves horizontally when the drive cam is lowered, and the passive cam. A die is provided for performing an offset bending process on the workpiece in cooperation with the provided offset bending blade, and the passive cam is provided with a offset cutting tool that is movable in a horizontal direction, and further,
A composite press mold for offset bending and offset processing, comprising a latch rotatably attached to the lower end of the drive cam, the rotation of which is restricted when the drive cam is raised, and which presses the offset cutting tool toward the workpiece.
