Abstract

The paper introduces ultrasonic vibration drawing (UVD) as a new technology for processing high mechanical resistance wires. A calculation method has been developed for the drawing force based on the theorem of total consumed power, considering a spherical rate field, a static flow, a Coulomb-type friction and the existence of the “reversion mechanism of average friction force” at metal-tool contact when the die is located in the oscillation maxima of the waves and ultrasonically actuated along drawing direction. Analytical results were in good agreement with experimental results obtained on ball-bearing steel wires. The advantages of UVD technology as compared to classical technology (CT) have been emphasized by means of the mechanical characteristics of resistance and plasticity determined from tensile tests of the correspondingly processed wires..
