Claims

[Claims for Utility Model Registration] In a forging die consisting of a forming punch and a forming die, an alignment elasticity that enables movement of each die in a direction perpendicular to the forming direction of the forming punch and forming die. A forging die structure with centering action, characterized in that a body is disposed between the die and a holder of the die.
