Principle
The basic composition of the sonic cutting machine is an Ultrasonic transducer, ultrasonic horn, ultrasonic cutter, and ultrasonic generator.
ultrasonic generator
The commercial power is converted into high-frequency and high-voltage alternating current, which is input to the ultrasonic transducer. The ultrasonic transducer is equivalent to an energy conversion device, which can convert the input electrical energy into mechanical energy, that is, ultrasonic waves. The ultrasonic transducer moves back and forth in the longitudinal direction, and the frequency of the telescopic motion is equal to the frequency of the high-frequency alternating 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 ultrasound.
Output ultrasonic waves, and use the cutting knife to concentrate the ultrasonic energy into the cutting part of the material to be cut. Under the action of huge ultrasonic energy, this part is instantly softened and melted, and the strength is greatly reduced. Only a small amount of force is required to achieve the purpose of cutting the material.
Classification
According to the ultrasonic cutting machine, the cutting method can be divided into a knife cutting machine and a chopping board cutting machine. Two cutting methods are suitable for different process conditions and cutting objects.
Knife
The knife-type cutting machine loads ultrasonic waves on the cutting tool, so that the tool generates ultrasonic vibration, so as to achieve the effect of cutting.
This cutting method is suitable for: raw rubber cutting, pipe cutting, frozen meat, candy, chocolate cutting, printed circuit board, natural fiber cutting, synthetic fiber deep digging, plastic shell processing, an artificial resin including paint, and hand-held cutting, etc.
Chopping board
The cutting board type cutting machine loads the ultrasonic vibration on the cutting bottom mold. This bottom mold is like the cutting board used in life, which makes the cutting board generate ultrasonic vibration, which can also have the effect of cutting, and the cutting tool does not need to be changed. Ordinary knives will do.
