FIELD: plastic working of metals, possibly relief deforming of thin-wall cylindrical bodies made of sheet.
SUBSTANCE: apparatus includes attachment for holding body and preventing its rotation; tool for deforming body in predetermined zone of its lateral surface. Said tool is in the form of set of segments forming supporting surface of cylindrical shape. Each segment is in the form of 1/2 of cylinder cut diametrically along its axis. Segments may be moved in vertical axial direction and in horizontal radial direction by means of tool moving mechanism. Said mechanism is in the form upper and lower cones mutually joined through rod. Upper cone is fixed to rod and lower cone is mounted stationary. Segments are mutually bonded trough elastic members for providing their simultaneous movement.
EFFECT: simplified design of apparatus, simplified deforming process.
