Abstract

APPARATUS AND METHODS FOR FORMING A PLURALITY OF ELONGATED MEMBERS A plurality of separate, elongated, metallic members, such as wires, are formed simultaneously, e.g., through the application of hydrostatic extrusion techniques, by passing a single metallic workpiece through a die with a plurality of apertures. The apertures extend longitudinally through the die from an entry wall of the die, and are so arrayed, and the die entry wall includes surfaces which are so configured, as to cooperate to create cross-shear stresses in the material of the workpiece in the vicinity of the apertures. These cross-shear stresses separate, or assist in separating, the workpiece into a plurality of elongated members, so that the forming process may take place at reduced operating pressures. -i-
