THE APPLICATION OF VIBRATIONAL ENERGY TO THE DRAWING OF METALLIC MATERIALS.

Abstract

Significant reductions in drawing force were obtained with all of the materials at the drawing rates noted. Surface finish was improved; cold drawing of the titanium alloy was practical with, but not without the application of vibratory energy. With the view to differentiating the effect of vibratory energy on die friction and on redundant deformation, high intensity ultrasonic vibration was applied during the steady-state drawing of copper and steel wire under varying conditions of area reduction, back-pull, drawing rate and ultrasonic power. It was not possible to differentiate between the ultrasonic effect on redundant deformation and the ultrasonic effect on die friction, but at the higher energy density the primary mechanism of the ultrasonic effect relates to friction reduction at the die-wire interface.
