Abstract
PURPOSE: To form a titled tooth profile of high accuracy and strength with small forming force by inserting a ringlike blank material between a lower die formed internally with the tooth profile and stamp forging dies which are split radially, and expanding the stamp forming dies in an outside diametral direction.
CONSTITUTION: A ringlike blank material 200 is inserted into the space in the tooth profile forming part of the inside circumference of a tooth profile die 130, and is disposed on the outside circumferential side of the flange part outside circumferential surface 144 of stamp forging dies 140. Next, a pressure die 110 is lowered so that its leading end face 111 is put in close contact with the top surface of the die 130. Then, the material 200 is put in an approximately tightly closed state except that it has a slight opposing clearance between the same and the tooth profile 131 of the die 130. Following this, a heading punch 100 is inserted into the tapered hole 141 of the die 140 through a through-hole 112. Thereby, the individual stamp forging pieces are pushed in the outside diametral direction. The material 200 is expanded from the inside circumferential side by the outside circumferetial surfaces 144 of the dies 140, and its outside circumferential side is filled in the tooth profile 131.
