Abstract
An apparatus for forming a cup-shaped cage, including a cup-shaped workpiece, an outer die having a center axis and a cavity about the center axis, an inner die coaxially disposed within the cavity of the outer die, and a mandrel adapted to move axially and radially the inner die relative to the outer die. The outer and inner dies have first and second control surfaces which are engaged with outer and inner surfaces of the workpiece, respectively, when the outer and inner dies are in the cooperative press position. The outer die includes a part allowed to be out of contact with the outer surface of the workpiece to permit the movement of the inner die relative to the outer die into the cooperative press position.
