Claims

[Scope of utility model registration request]

A die supporting a workpiece having a cylindrical body portion and a radial end plate portion is attached to the lower die, a cutting edge is formed at the lower end of the outer peripheral surface of the die, and the tip surface has a convex shape and cooperates with the cutting edge. a first punch that cuts an end of the workpiece by cutting the workpiece, and a second punch whose tip surface has a concave shape and cooperates with the cutting blade to cut the end of the workpiece. A scrap cutter is provided on a slide cam that is movably attached to the die and cuts the scrap cut from the workpiece into parts in cooperation with the punch, and the workpiece is supported by the radial end plate portion. An auxiliary lifter for lifting is attached to the lower die, and a main lifter for lifting the work while supporting the work on the main body, the main lift having an engaging claw for supporting the lower end surface of the work after the auxiliary lifter lifts the work for a predetermined stroke. is attached to the lower die.
