Abstract: PURPOSE:To prevent a gall from generation and to easily pull an internal gear out of the tooth die after it is formed by generating a temperature difference between a punch and a formed internal gear so that the temperature of the punch is lower than that of the formed internal gear. CONSTITUTION:A billet 22 is contracted in diameter by plural forming dies 20 which fit a billet 22 to a mandrel punch 12 provided with a tooth die 14 corresponding to the teeth on the outer peripheral surface, can move in the radial direction of the punch 12 and whose surfaces on the punch side form a recessed surface corresponding nearly to the outer peripheral surface of the internal gear 70 and plural teeth are formed on the inner peripheral surface. Thereafter, the temperature of the punch 12 is lowered to that of the internal gear 70. Therefore, the temperature of the punch 12 is lowered than that of the internal gear 70, and the punch 12 is contracted in diameter, the clamping force of the punch 12 by the internal gear 70 is reduced and a small clearance is generated between the internal gear 70 and the punch 12. Consequently, when the internal gear 70 is pulled out, the internal gear 70 can be pulled easily out of punch 12.
