Abstract
Device for rolling rolling-contact bearing races from a blank by means of a die and shaping wheels comprising an inner roller for obtaining the internal profile of the race in the die from which it is separated to permit a possible extrusion of the excess material of said blank, and an outer wheel for shaping part of the external profile of the race against the action of the inner roller, said die being divided in the axial direction into two separable sections disposed on either side of said outer wheel in a die support and constituting a cavity of which the profile is designed for shaping the portions of the outer profile of the race which are adjacent to those shaped by said roller, the two die sections being fitted for free rotation in said die support.
