Claims

[Scope of utility model registration request]

A positioning device that positions a press work placed on a lower die using the lowering of the upper die prior to press working, and is capable of moving back and forth to a position corresponding to the work side edge on the upper surface of the lower die. a positioning member which is attached to the upper mold and is always urged in the backward direction by an elastic member; a blank holder which is held on the outer periphery of the upper mold so as to be movable up and down with respect to the upper mold; and a blank holder which is attached to the upper mold or the blank holder. a cam member that advances the positioning member when descending to bring it into contact with the workpiece side end, and allows the positioning member to be retreated by the elastic member just before the blank holder presses the work; and a lower part of the blank holder. 1. A press work positioning device comprising: a pressing member which is provided at a press member and which presses the work by the urging force of an elastic member before the positioning member retreats.
