technical field [0001] The invention relates to the technical field of ultrasonic processing equipment, in particular to an ultrasonic longitudinal torsional vibration processing device and a processing technology. Background technique [0002] Composite materials such as carbon fiber have excellent properties such as high strength, high temperature resistance, wear resistance and corrosion resistance, and have been widely used in machinery, electronics, aviation, automobiles and other fields. However, it is these characteristics that increase the processing difficulty of composite materials such as carbon fiber. Traditional processing methods have low processing efficiency and high cost, which limits the further application of composite materials such as carbon fiber. With the development of science and technology, special processing came into being and developed rapidly.

AI Technical Summary

Problems solved by technology

[0003] The current ultrasonic vibration processing system mostly uses contact power transmission power supply. There is mechanical wear and friction between the power supply system and the load, which increases the loss of the system, and due to the existence of the brush, the rotation speed of the tool is limited, thereby limiting the processing quality. and efficiency

The non-contact power transmission method effectively solves the above problems, but the non-contact power transmission method has high requirements on the parameters such as the core gap of the primary and secondary windings, and the power transmission efficiency is low, which limits the application of this method
