FIELD: plastic metal working; methods of rotary extrusion of tubular blanks. SUBSTANCE: proposed method includes placing the blank on mandrel, performing rotary extrusion by deforming members and removal of finished part. According to first version, rotary extrusion is performed by at least two passes alternating direct and backward extrusion at first and second passes. According to second version, rotary extrusion is performed by at least two passes by direct and backward methods; blank is removed from mandrel after first pass and is set at turn of 190 deg. EFFECT: reduction of distortion of geometric shapes; enhanced stability of blank. 3 cl, 4 dwg, 2 ex
