Abstract

PURPOSE: To faciliate correct finishing by premolding the side wall part of a premolded article into V-groove form by means of an auxiliary groove forming body having a molding surface in V-shaped section, in manufacturing a sheet metal pulley in which disc part diameter is larger than the inner diameter of the V-shaped groove bottom part.
CONSTITUTION: When the sheet metal pulley 6 of which disc part diameter d1 for magnetic clutch is larger than the inner diameter d2 of the V-shaped groove bottom part is manufactured, the premolded article 1 in based cylinder form is put between a revolving receiving mold 2 and a revolving pressing mold 3, and a compression force is applied in the axial direction in revolution. A premolding roller 5 having premolding surface 5a in V-shaped section is pushed onto the side wall part 4 of the premolded article, and the premolded article is molded into the V-shaped groove form which bends linearly. Then, with the revolution of revolving molds 2 and 3, compression force is applied furthermore, and the groove forming roller 15 is pushed onto the premolded groove, and the bending angle is reduced, and a V-shaped groove 13 is complated. As the premolded groove bends linearly, formation of bulge of the V-shaped groove in the final stage is eliminated, and correct finishing can be obtained easily.
