Zusammenfassung:	An integral spinning belt pulley forming process comprises the following steps that blanking is conducted, specifically, a steel plate or a steel belt is cut into a round blank through stamping or laser cutting; drawing: drawing the circular blank into a cylindrical blank by adopting a drawing process; a boss is shoveled and spun, specifically, spinning is started from the middle of the upper end face of the cylindrical blank, local materials flow from the periphery to the center under the action of pressure, meanwhile, the materials protrude upwards to form the needed annular boss, and meanwhile an annular upper groove is formed; shaping: shaping the spun blank on an oil press or a punching machine to form an upper reinforcing groove and a lower reinforcing groove; edge turning: putting the shaped blank on a lathe to perform edge turning on the lower end surface of the blank; spinning a belt pulley groove: putting the blank on a spinning machine to form the belt pulley groove through spinning; finish turning
