Abstract
Description
technical field
[0001] The invention relates to an extrusion processing device, more particularly, to an ultrasonic elliptical vibration extrusion processing device based on a dual-excitation longitudinal bending elliptical transducer. Background technique
[0002] The ultrasonic vibration transducer is the most important part of the ultrasonic vibration processing system, and its design effect directly affects the processing quality. In general, the transducer itself has three vibration forms: longitudinal vibration, bending vibration and torsional vibration. When the two vibration forms are combined with a certain phase difference, elliptical vibration can be obtained. Most of the longitudinal bending elliptical vibration transducers currently used use a single-excited asymmetric structure horn to obtain the elliptical vibration form. However, the controllability of the elliptical vibration obtained through this transducer is poor, which is not conducive to better processi...
