Abstract

The invention aims to provide an ultrasonic power synthesis vibrating system capable of generating elliptical vibration, namely a power synthesis tube and wire drawing device capable of generating elliptical vibration, particulary applicable to high-power cold drawing of metal tubes, wire drawing and other ultrasonic engineering. To achieve the effect, the power synthesis tube and wire drawing device capable of generating elliptical vibration comprises an energy collecting ring, wherein at least three ultrasonic transducers are arranged at the outer side of the energy collecting ring evenly, the energy collecting ring is provided with a vibration displacement pitch line, at least three slits are arranged evenly along the vibration displacement pitch line, and the center of each slit is arranged on the vibration displacement pitch line and forms a certain included angle with the radius of the energy collecting ring. By adopting the technical scheme, the elliptical vibration cold drawing effect of the power synthesis tube and wire drawing device is better than that of single ultrasonic vibration drawing, thus further improving the surface finish of a tube, reducing the drawing force, improving the extension coefficient of a material and enhancing the processing precision of a drawn tube.
