Abstract
PURPOSE: To reduce machining parts and improve yield by beforehand forming the shape of a blank material to the shape of a product.
CONSTITUTION: A blank material M is fitted to the mandrel 1 in a die 2. The material M consists of a boss part 8' and a tooth profile part 9'. The boss part 8' of the material M has an outside diameter equal to or slightly smaller than that of the boss part 8 of the product and the tooth profile part 9' has an outside diameter equal to or slightly smaller than the bottom diameter in the part 9 of the product. If this material M is pressed by a punch 6 corresponding to the bottom diameter, the part 8' deforms according to the space enclosed by the mandrel 1, the die 2 and the punch 6, and the part 9' is extruded in the direction of the chamfered part 5 and the tooth profile forming part 4 on the inner side of the die, whereby the part 9 is formed. An excess metal part 10 is removed by machining to make the product.
