FIELD: machine building.
SUBSTANCE: invention relates to machine building and can be used in metallurgy to increase the accuracy of curved pieces dimensions. Machine comprises stationary drive rollers for movement of the workpiece and bending rollers performing reciprocating movement. All rollers are arranged along a circular arc corresponding to the workpiece shape. Bending rollers are made with the possibility of reciprocating movement in radial directions. Herewith the bending rollers and the drive rollers are equipped with drives of movement in radial directions.
EFFECT: higher accuracy of dimensions and curvature of curved pieces is ensured.
