ABSTRACT:
A process for manufacturing toothed parts having a tooth profile on a portion of their outline. The process utilizes a press machine having top and bottom die sets with stock interposed therebetween at uniform intervals in sequence with the vertical operation of the press machine. The process includes a first step wherein a center hole is stamped in said stock and, a second step wherein a window hole corresponding to the exterior peripheral tooth profile is stamped in said stock using the center hole as a reference, a third step wherein a tooth profile having a tooth width greater and a tooth height lower than the final tooth profile is rough-formed on one side of said window hole, and a fourth step wherein the exterior periphery of said rough-formed toothed part undergoes stamping and ironing operations concurrently with the processing of the final tooth profile.
