Working principle of ultrasonic rolling

Ultrasonic rolling is to apply ultrasonic vibration on the basis of ordinary rolling process, and its working principle is shown in Figure 1. During rolling processing, the transducer receives the high oscillation signal from the ultrasonic generator, which is converted into a weak mechanical vibration horn through piezoelectric conversion, and then amplifies the mechanical micro-amplitude of the transmitter end of the transducer to the mechanical amplitude required for processing, and The rolling head connected to the horn is under the action of small static pressure, high-frequency mechanical vibration and the hammering and feeding motion, the convex part of the surface of the part is filled to the concave part, forming a uniform and refined gold The hard surface layer of phase structure achieves the effect of smoothing and strengthening the surface of parts.

According to the working principle of ultrasonic rolling, the transducer is the energy conversion component in ultrasonic rolling, and it is also a key component of the ultrasonic rolling device. Its design is directly related to the process effect of ultrasonic rolling.
