FIELD: plastic metal working, namely hot multiple-stage forming on turntable with dies. SUBSTANCE: method comprises steps of charging hot blank to die in initial position, step-by-step transporting blanks in dies along circular path with constant stroke, descending punches for joining them with dies and supplying liquid coolant onto tool. Step-by-step transportation of blanks is realized at odd number of strokes for one revolution of turntable. Next hot blank is charged to respective die after next one stroke of rotary turntable.
