FIELD: equipment for manufacture of presswork with the main shaped members having the shape of a cylinder, and auxiliary shaped members having a helical shape, of powdered material, in particular, of metal powder. SUBSTANCE: device has a female die and at least one upper male die located for rotation about its longitudinal axis, as well as at least one lower male die located for rotation about its longitudinal axis; the upper and lower male dies may axially move with the motor drive relative to the female die, and at least the upper male die in addition to its axial drive has a drive of rotation about its longitudinal axis for movement along helical line. The device is furnished with an electronic control system, and at least one lower male die has also a rotation drive, each rotation drive of the male dies is mechanically disconnected from the drives of axial movement of male dies and has a possibility of separate adjustment of the electronic control system; the upper and lower male dies directly participating in forming of auxiliary members of presswork having a helical shape in their movement in the female die cavity are directed by means of the electronic control system. EFFECT: reduced pressing force due to reduced friction, simplified readjustment of tool in manufacture of different presswork. 15 cl, 1 dwg
