Abstract

PURPOSE: To form the revolving-field pole piece in excellent yield without using a press of great capacity, by forging slag with fixed volume into a semimanufactured good with a substrate portion, a shaft portion and radial projecting pieces, and by bending the projecting pieces in the axial direction.
CONSTITUTION: A semimanufactured good, to which a shaft portion 102 with a lower hole 104a, a substrate portion 101 with prescribed thickness and projecting pieces 103a radially projected around the substrate portion 101 are made up, is obtained by treating columnar slag, which has volume necessary for a product and length in standard size, by means of foward extruding working, swaging working, side extruding working, etc. A pawl piece 103 with a shape approximately close to the product is built up in such a manner that a shaft hole 104 is formed, and the projecting pieces 103a are made up in cuneiform shapes with tapered sections while being prolonged in the axial direction by bending-working the projecting pieces in the axial direction as applying drawing working. Lastly, a finished-product 100 of this pole piece is gained by molding each portion by means of molding working.
