Beschreibung
Zusammenfassung:	The invention relates to the field of metal forming, especially, to the technology of forming with rotation of tool. A device for forming of axially symmetrical parts with twisting contains a housing with central hydraulic cylinder with a piston made in it, stock of which is connected with a nut on the screw thread, and also a moving plate, in which the nut is fixed, and lateral hydraulic cylinders with plungers connected to moving plate, moreover, central hydraulic cylinder is connected with lateral cylinders by means of direct-action hydraulic valve and hydraulic check valve. The proposed device makes it possible to reduce force and to reduce energy consumption of deformation of axially symmetrical parts.
