Abstract

A cup shaped stainless steel blank is deep drawn into a closed end hollow shape having a thickened bottom and a thickened rim at its open end. A ram for forcing the blank through a drawing die has a forward plunger portion and a conical body portion merging with and tapering rearwardly from the plunger portion. Axial forward thrust of the ram forces its plunger portion into the blank and pushes the latter through the drawing die, thereby transforming the blank into an elongated hollow shape having a uniform outside diameter from end to end and an inwardly projecting rim at its open end. Stripping of the elongated hollow shaped from the ram radially distends the inwardly projecting rim so that the stripped hollow shape will have the same inside diameter from end to end.
