An apparatus for radial compression forming and axial direction forming of metal articles, of the type such as steel automobile wheels, with auxiliary machining operations being performed in the same work station. The wheel formed from several pressed component pieces including an outer flange and central spider is fitted into the open annularly disposed jaws of a shrink forming head whereupon the compression forming operation is performed by contraction of the jaws in the radial direction. The apparatus includes a concentrically disposed axially driven piston carrying tool means for deforming the web portion of the wheel to correct axial run-out or establish perpendicularity of the web with respect to the flange portion. The axially driven piston and tool means is fluid powered so as to enable sensing contact with the web portion by the tool means and thereafter imparting a predetermined amount of axial movement to deform the wheel web by a corresponding predetermined amount. |
