Abstract
PURPOSE: To move plate thickness from the tooth face to the angle part and form the tooth profile of high accuracy by swiftly ironing the tooth face in the final forming when forming the tooth profile to the rim part of the rotating part for transmission which comprises pressing a plate material.
CONSTITUTION: A sheet of plate material is blanked and drawn with its plate surface as a reference to form a cylindrical part 1 and a flange part 2. Next, with the cylindrical part 1 as a reference, it is deep drawn integrally with a reinforcing rib 4 in such a manner that the plate thickness of the corner becomes thicker than a bearing part 3. Thence, with the flange part 2 as a reference, a rim part 5 is drawn and a through-hole 6 and through-hole 7 are blanked. After a tooth profile 8 is bent by ironing the circumferential edge of the rim part 5, it is ironed subsequently so that the bottom A and tip B become of the specified shape and size accuracy. Thence, the tooth face C is swiftly ironed to cause plate thickness movement toward the angle part r1 and curved part r2, thereby preventing the decrease in the plate thickness at the angle and curved parts and form the radius of bending small.
