Title: Gear tooth forming die
Inventor: NISHIUCHI SHOHACHI
IPC: B21K1/30
Filed: 1995-12-28
Abstract: PROBLEM TO BE SOLVED: To enhance the precision of a gear tooth forming die forming helical splines and to extend its life. SOLUTION: As approach faces 2a, the left and right shape of which is different, are formed in a straight tooth 2 of a gear tooth forming die 1, a stock 5 is entered in the right or left direction when the stock 5 is pushed into the gear tooth forming die 1. Therefor, the stock 5 is formed into a helical spline 8 by pushing the stock 5 into the gear tooth forming die 1 while turning the stock 5 in the right or left direction. As the straight tooth 2 is positioned so that its longitudinal direction is parallel to the advancing direction of a punch 6, the precision of the shape of the straight tooth 2 is easily corrected with a lapping bar or the like after electrical discharging machining is applied to the straight tooth 2.  Further, when the stock 5 is pushed into the gear tooth forming die 1, the pressing force from which the side face of the straight tooth 2 receives is restrained so as to become small.
