Description

technical field [0001] The invention relates to an ultrasonic wire drawing vibrator with a single drive to realize orthogonal compound vibration, and belongs to the technical field of ultrasonic vibration drawing vibrator. Background technique [0002] Piezoelectric ultrasonic vibration wire drawing is a processing technology in which ultrasonic vibration energy is superimposed in the conventional wire drawing process. The alternating electric signal generated by the ultrasonic driver is converted into ultrasonic vibration energy through the piezoelectric sheet, and then the ultrasonic vibration is amplified and matched by the horn. It can be transmitted to the wire drawing die to excite the vibration of the wire drawing die, and then the material to be processed is drawn through such a vibrating die to obtain the effect of ultrasonic vibration energy on the plastic forming of metal materials. [0003] The ultrasonic vibration drawing in the prior art is mostly longitudinal ...

AI Technical Summary

Problems solved by technology

Although its structure can realize the orthogonal compound movement of the wire drawing die, since the transducer and the horn are located on both sides of the ultrasonic vibrator installation surface, part of the ultrasonic vibration energy is transmitted backward; at the same time, the two ultrasonic longitudinal ultrasonic vibrators are mechanically connected at the output end. Connection, additional load is formed between vibrators, so it is difficult to achieve large-amplitude ultrasonic compound motion

The existing orthogonal oscillators have disadvantages such as poor practical applicability, high energy consumption, small output displacement, and difficulty in heat dissipation.
