ABSTRACT:
An apparatus and method for forming a power transmission member from a thin-walled blank, the apparatus including a pair of dies (84) having opposed work surfaces, and a mandrel (50) positioned between the work surfaces of the dies (84) for receiving a blank (52) to be formed and rotated upon movement of the work surfaces of the dies in opposite directions during a forming operation. The mandrel (50) includes a work surface for cooperating with the work surface of the dies (84). Notch forming projections (70) on the work surfaces of the dies (84) cooperate with the work surfaces of the mandrel (50) for roll punching notches (72) through the blank (52) as the blank (52) is rotated between the moving dies (84).
