ultrasonic knife to cut plastic 20khz/28khz/30khz/35khz/40khz

The basic structure of acoustic cutting machine is composed of. Ultrasonic transducer, ultrasonic horn, ultrasonic cutter, ultrasonic generator.

The ultrasonic generator

The mains power is converted into high frequency and high voltage AC current, which is transmitted to the ultrasonic transducer. The ultrasonic transducer is equivalent to the energy converter, which can convert the input electric energy into mechanical energy, that is, ultrasonic. The ultrasonic transducer moves back and forth in the longitudinal direction, and the frequency of the movement is equal to the frequency of the high frequency AC current supplied by the driving power supply.

Ultrasonic horn

The ultrasonic horn amplifies the output amplitude of the ultrasonic transducer.

Ultrasonic cutter

Further amplify the amplitude and focus the ultrasonic wave.

Output ultrasonic wave, use cutting knife to input ultrasonic energy to the cutting part of the material to be cut. Under the action of huge ultrasonic energy, this part softens and melts instantly, and its strength drops greatly. The purpose of cutting materials can be achieved only by applying a small amount of force.
