FIELD: metal pressure forming. SUBSTANCE: method comprises steps of reducing a blank of rectangular cross section in radial and tangential directions over separate passes; forming at each subsequent pass a blank with square-cross section, whose central axis is displaced relative to a central axis of the blank of a previous pass; providing a displacement of the axis of the square-cross section blank after each pass in a circular direction by a symmetrical reduction of faces of the blank. It is possible to provide a shift of the central axis of the square-cross section forming in the circular direction upon each pass after each reduction stage. EFFECT: enhanced efficiency. 3 cl, 8 dwg
