Abstract
PURPOSE: To mass-produce a product having a high accuracy by bringing a preform which has been formed in a shape of a cup, to a stepped part working and a bearing supporting part working, and thereafter, forming a V-groove in a wall thickened bulge part which has been formed in a V-groove forming part, and subsequently, pressing a ready-made bearing into a bearing fitting and attaching part.
CONSTITUTION: A sheet metal stock of prescribed thickness and outside diameter is brought to deep drawing, and a cup-shaped preform 11 consisting of a base plate part 21 and a rough peripheral wall part 22 is formed. By a preliminary form rolling, an inclined stepped part 31 is formed on the rough peripheral wall part 22, a bearing supporting part 42 and a base plate part 43 are formed by a drawing working, and thereafter, a wall thickened bulge part is formed by an outer drawing die. Subsequently, by a multi-V-groove preliminary forming roller which serves as a wall thickening roller, too, the wall thickened bulge part 51 is thickened, and also a multi-V-groove 61 is formed after forming a reference part 62. In the end, a ready-made bearing 91 is pressed into the bearing supporting part 42. According to this method, a product having a high accuracy can be mass-produced.
