FIELD: metallurgy.
SUBSTANCE: invention relates to metal deformation process and can be used at manufacturing of products of cylindrical work, shaping. Preheated cylindrical work is deformed on press in preheated closed die. Die contains puncheon, bottom semimartingale and upper semimartingale with through cylindrical cavity. Upper matrix overlaps die by internal diametre of bottom semimartingale and allows translational displacement. Cylindrical work is installed by axis of bottom semimartingale in through cavity of top semimartingale. It is settled work by puncheon with providing of upper semimartingale lifting under the action of feeding into the die cavity of work material. Then it is deformed settled work with receiving of finished product by joint omission of upper semimartingale and puncheon.
EFFECT: it is provided increasing of productivity and quality of finished products, assortment broadening.
