Intensification of tube drawing by axial ultrasonic oscillation of the plug

During tube drawing with axial ultrasonic oscillation of the plug at high intensities, a dynamic force occurs, the magnitude of which is comparable with the forces of plastic deformation of metallic materials. Significant reduction in the drawing force is then obtained with the possibility of intensification of the drawing process, especially for metals and alloys with low deformability. It has also been observed that, for constant oscillation amplitude of the plug, the reduction in the drawing force decreases with increasing drawing velocity.
