Abstract

PURPOSE: To produce the captioned pulley for flat belt, rigidly, easily and at high precision, by forming a single recess groove in the cup-shaped blank, continuously forming a plurality of recess grooves in the peripheral wall by bulging, and pressing the inner and outer faces of the peripheral wall with shaping rollers to shape each recess groove into specified form.
CONSTITUTION: A circular blank blanked out from a steel sheet is drawn into a stepped cup-shaped blank 1, which is drawn by rollers to form a single recess groove 2a of a wide opening width in the peripheral wall 1a. This premolding 2 is bulged to obtain an intermediate molding 4 having a plurality of recess grooves 4b... of narrow opening width in the peripheral wall 4a. This molding 4 is set in a rotary die 10 of a shaping device 9, and rotated and driven. Raising the rotary die 10, a inner groove shaping roll 11 is put into the molding 4 and is offset, then an outer groove shaping roll 12 is approached so as to press the molding 4 with the both rolls 11, 12. Finally shaping each recess groove 4b... into the specified V- shaped groove, a completed product of pulley 13 is obtained.
