Problems solved by technology

In actual application conditions, there is also a requirement to change the vibration mode. For example, most of the conventional ultrasonic longitudinal vibration excitation devices work in the longitudinal vibration mode, and it is not convenient to directly connect and drive the bending vibration tool. Convert to bending mode

Description

technical field [0001] The invention relates to the application field of power ultrasound, in particular to a longitudinal vibration bending vibration ultrasonic horn. Background technique [0002] The ultrasonic horn is an important part of the ultrasonic vibration system. The main function of the traditional ultrasonic horn is to transmit ultrasonic vibration and change the amplitude of ultrasonic vibration. In actual application conditions, there is also a requirement to change the vibration mode. For example, most of the conventional ultrasonic longitudinal vibration excitation devices work in the longitudinal vibration mode, and it is not convenient to directly connect and drive the bending vibration tool. At this time, a device is required to convert the longitudinal vibration mode Convert to bending mode. Contents of the invention [0003] The problem to be solved by the present invention is to make up for the above-mentioned defects of the prior art, and to provi...
