Ultrasonic cutting machine is a kind of ultrasonic equipment specially used for cutting, and is one of the important categories of ultrasonic applications.
The principle is completely different from traditional cutting. Ultrasonic cutting machine uses the energy of ultrasonic wave to heat and melt the material to be cut locally, so as to achieve the purpose of cutting material.
Ultrasonic cutting machine features no sharp blade, no pressure, no chipping or damage to the cutting material.
The cutting blade is doing ultrasonic vibration, the friction resistance is particularly small, and the material to be cut is not easy to stick to the blade. It has obvious cutting effect on frozen, sticky and elastic materials. Such as food, rubber or inconvenient to cut pressure object is particularly effective.
At the same time as cutting, the cutting part has fusion effect. The cutting part is perfectly edge-sealed, which can prevent the looseness of the cut material (such as textile material flash). The use of ultrasonic cutting machine can also be expanded, such as digging holes, shoveling, scraping paint, carving, slitting, etc.
The basic structure of sonic cutting machine. Ultrasonic transducer, ultrasonic horn, ultrasonic cutter, ultrasonic generator.
The mains electricity is converted into high-frequency high-voltage alternating current, which is transmitted to the ultrasonic transducer. Ultrasonic transducer is equivalent to energy conversion device, it can convert the input electrical energy into mechanical energy, that is, ultrasonic. The ultrasonic transducer moves back and forth in the longitudinal direction, and the frequency of the stretching motion is equal to the frequency of the high-frequency alternating current supplied by the driving power supply.
The ultrasonic horn amplifies the output amplitude of the ultrasonic transducer.
1. Amplify the amplitude further and focus the ultrasound.
2. Ultrasound is output, and the ultrasonic energy is concentrated and input to the cutting site of the material to be cut using a cutter. Under the action of huge ultrasonic energy, this part instantly softens and melts, and its strength is greatly reduced. Only a small force is needed to achieve the purpose of cutting materials.
