FIELD: plastic working of metal, in particular, manufacturing of wheels with equal thickness and shape of disk and hub independent of different weight of basic workpieces. SUBSTANCE: method involves upsetting starting workpiece and bringing starting workpiece to speed by punch; centering in forming die and forming workpiece by hot forging. Forming is effectuated in two stages. At the first stage rim and disk are formed by moving upper part of forming die, with disk thickness being equal to thickness of disk of ready product. At the second stage hub with cavity and web portion are formed by movable punch, with upper part of forming die being fixed relative to lower part. EFFECT: increased efficiency and high quality of wheels. 3 dwg
