Ultrasonic cutting machine
Ultrasonic cutting machineThe characteristic is that it does not require sharp blades, does not require too much pressure, and will not cause damage to the cutting material. The cutting knife adopts ultrasonic vibration, the friction resistance is small, and the cutting material is not easy to stick to the blade. It has obvious cutting effect on freezing, viscous and elastic materials. For example, food, rubber and other objects that are not easy to cut under pressure.
While cutting, the cutting part has a fusion effect. The trimming part can prevent the cut material (such as textile material flashing) from being loose. The use of ultrasonic cutting machines can also be expanded, such as digging holes, shoveling, scraping paint, carving, cutting, etc.
The difference with traditional cutting:
Ultrasonic cutting machine is a kind of equipment that uses wave energy for cutting processing. The characteristic is that traditional edges are not used.
The traditional cutting method is to press down the material to be cut with a sharp knife. The pressure is concentrated on the blade. The pressure is too large, exceeding the shear strength of the material being cut. The molecular bonds of the material are pulled apart and cut. Because the material is pulled hard by strong pressure, the cutting edge of the tool should be very sharp, and the material itself should bear a lot of pressure. The cutting effect of soft elastic materials is not good, and the cutting of viscous materials is difficult.
The basic structure of sonic cutting machine consists of the following parts: ultrasonic generator, ultrasonic horn, ultrasonic cutting machine, ultrasonic generator.
1. Ultrasonic generator
The electrical energy is converted into high-frequency and high-voltage alternating current and transmitted to the ultrasonic transducer. The ultrasonic transducer is equivalent to an energy converter, which can convert the input electrical energy into mechanical energy, namely ultrasonic waves. The ultrasonic transducer moves back and forth in the longitudinal direction, and the moving frequency is equal to the frequency of the high-frequency alternating current provided by the driving power supply.
2. Ultrasonic horn
The ultrasonic horn amplifies the output amplitude of the ultrasonic transducer.
3. Ultrasonic cutting knife
a. Further amplify the amplitude and focus the ultrasound.
b. Output ultrasonic, and use a cutting knife to input ultrasonic energy into the cutting part of the material to be cut. Under the action of huge ultrasonic energy, the parts instantly soften and melt, and the strength is greatly reduced. Only a small amount of force can achieve the purpose of cutting the material.
