Claims

[Scope of utility model registration request]

A forging press die device that performs finish forging while bending a preformed workpiece whose volume has been distributed so as to correspond to a forged press product using a die having an ejector pin and a punch having a hold pin. A positioning part is formed at the entrance of the mold recess formed in the mold, into which both ends of the preformed work are positioned and fitted, and a substantially central part of the preformed work is held between the ejector pin and the hold pin. A forging press die device that is characterized by:
