Abstract
An apparatus (10) and die assembly (26, 30) for forming a splined power transmission member from a thin-walled blank. The apparatus (10) comprises a pair of die assemblies (26, 30), each including a supporting frame (28), first (42) and second (44) die bodies independently mounted on the supporting frame (28) in end-to-end coaxial relationship with each other, with rough (46) and finish (48) spline-forming surfaces formed on the first (42) and second (44) die bodies, respectively. The pair of die assemblies (26, 30) are supported with the spline-forming surfaces of the respective die bodies (42, 44) in spaced, oppoosed, parallel relationship to each other. A power drive mechanism sequentially moves the pair of die assemblies (26, 30) in opposed directions. The power drive means effectuates a rough spline-forming stroke and then returns the die assemblies (26, 30) to the neutral position.
