FIELD: metallurgy.
SUBSTANCE: formation of parts is performed with pressure and support elements in the form of puncheon and matrix with creation of plastic contact at interaction points of the tool with the workpiece. Pressure is created and allows reaching the workpiece material yield point in sections of the part with single curvature owing to non-tight contact of working surfaces of pressure and support elements. Excess pressure is created in sections of the part with double curvature owing to tight contact of pressure and support elements till the required thinning of those sections is obtained.
EFFECT: increasing intensification of the deformation process.
