FIELD: metal pressure shaping; forming required microstructure in blanks, submicrocrystalline and nanocrystalline structure inclusive and physico-mechanical properties corresponding to structural state. SUBSTANCE: proposed device includes punch and sectional container with inlet and outlet parts which are engageable over parting plane and are provided with passage intersecting in above-mentioned plane. Passage are bounded by circle in parting plane. Inlet and outlet parts of container are mounted for rotation relative to each other in parting plane relative to each other. At least one passage or part of its adjoining parting plane has elliptical cross section. Passage of outlet part of container or passages on inlet and outlet parts may also have such cross section. In second case, cross sections of above-mentioned passages may have similar or different elliptical form. Passage of outlet part of container may be narrowed in shape. Cross-section area of this passage may be less than that of passage of inlet part of container. EFFECT: extended technological capabilities; improved quality of treatment. 6 cl, 8 dwg, 1 tbl, 6 ex
