ABSTRACT:
Apparatus and a method of employment thereof for forging cylindrical shells of controlled interdimension wherein a single punch die mandrel and cushion cooperate at a single work station to subject a metal blank to high multi-axial stress sufficient to increase the ductility thereof and permit a completed article to be fabricated during a single continuous pass of the material through the die. Precise control of the interdimension of the desired part is maintained by means precisely shaping the material and maintaining engagement between the end face of the mandrel and the bottom of the work blank during the forging process.
