Abstract: A method and apparatus for forming metal wheel assemblies having a rim and attached spider. A pair of outer dies complementary to the final radial form of the wheel rim are moved together to enclose an annular metal workpiece. A pair of horizontally opposed conical dies are then moved interiorly of the outer dies and annular workpiece. Each conical die has an annular stuffing ledge which contacts the edge of the workpiece. Force is then exerted against the workpiece edges so as to plastically regenerate the workpiece between the conical dies and outer dies; thus, providing thickening of the material in desired areas. A spider extending across the workpiece is axially loaded with the conical dies causing plastic deformation of the spider. A center rod mounted to and projecting from one of the conical dies is concentric with the conical dies and extends through the spider as the spider plastically deforms therearound. A groove formed in one of the conical dies forms a seating ridge in the spider which is defined by a plane perpendicular to the longitudinal axis of the wheel rim. A plurality of seating bosses are formed into the spider by the conical dies.

Abstract: The method of forming metal billets into desired cylindrical and circular shapes by imposing a squeezing force on the billet to cause the metal to flow in a direction for obtaining the desired shape while simultaneously imposing an additional force operating in a direction the same as the direction of metal flow caused by the squeezing force to assist the flow caused by the squeezing.
