ABSTRACT:
A cold forming method for plastic deformation process of toothed ring-shaped products (W0) have a tooth profile portion (T) in at least one of the outer peripheral surface and inner peripheral surface thereof. When processing a ring-shaped product (W0) having a tooth profile portion (T) in the outer peripheral surface, a die (1) is utilized. The die (1) has a tooth forming part (4) having a shape corresponding to the shape of the tooth profile portion (T) of the ring-shaped product (W0) in its inner peripheral surface, and, if necessary, a tip shaping part (5) positioned in the groove of the tooth forming part (4). A ring-shaped material (W) is pressed and passed into the die (1) by a punch (2) in a round shaft shape in the axial direction, and processed. When processing a ring-shaped product (W1) having a tooth profile portion (T) in an inner peripheral surface, the tooth forming part (4) and tip shaping part (5) are provided on the outer circumference of a lower punch ( 11), and the ring material (W) is pressed and passed into the lover punch (11) by an upper punch (12), and processed.
