Abstract

The machine has several blade punches (1), equal to the number of splines, spaced radially around the part (2). These punches have their outer edges at an angle and fit into a holder (3) which permits radial movement. A thin cone shaped ring (9) is placed over the punches, forming a cage. This is centred between one or more pairs of rollers (11), angled to match punches and ring. The distance between the rollers is less than the ring diameter. As the rollers rotate and move axially, the ring is deformed. This forces the blade punches into the part, cold forming the splines or serrations.
