WIRE DRAWING APPARATUS USING VIBRATORY-MECHANICAL ENERGY AND CURVED TRANSMISSION LINE

摘要

Apparatus for drawing wire utilizing a piezoelectric electromechanical transducer and an axially drilled curved transmission line in conjunction with a wire-drawing die to reduce the cross section of the wire. Static force exerted on the die by retaining diaphragms hold the die intermittent contact with the free end of the transmission line.
