Abstract
Apparatus for flanging and splining a thin-walled blank to make a splined and flanged power transmission member (42). A toothed mandrel (40) is rotatably supported between a pair of toothed dies (26,30; 112,114; 138,140). The dies and mandrel have chamfered surfaces (68,70) for forming a flange (66) on the thin-walled member as the toothed surfaces of the dies and mandrel are relatively moved during a spline forming operation.
