ABSTRACT:
A device for shaping the outer surface of a workpiece in which a sleeve is resiliently deformable in a radial direction. The sleeve is placed coaxially within a flywheel and removably fastened in a body member. A ring-shaped tool is coaxially located within the sleeve. The tool has at least five forming segments uniformly disposed on the circumference of the tool. The segments are integrally connected to one another by means of a neck portions which extend on at least one of the two axial sides of the tool. The tool is rotationally mounted in the body by means of an adjustment bushing. At least two rolls are located between the outer surfaces of the sleeve and the inner surface of the flywheel such that the rolls press the sleeve against the forming segments of the tool to deform the segments radially inwardly. The rolls are mounted in a cage which fixes their mutual angular positions.
