The basic structure of the acoustic wave cutting machine. Ultrasonic transducer, ultrasonic horn, ultrasonic cutter, ultrasonic generator.
The utility power is converted into a high-frequency high-voltage alternating current and transmitted to an ultrasonic transducer. An ultrasonic transducer is equivalent to an energy conversion device that converts input electrical energy into mechanical energy, that is, ultrasonic waves. The ultrasonic transducer rotates back and forth in the longitudinal direction, and the frequency of the telescopic movement is equal to the frequency of the high-frequency alternating current supplied by the driving power source.
The ultrasonic horn amplifies the output amplitude of the ultrasonic transducer.
Further amplify the amplitude and focus the ultrasound.
The ultrasonic waves are output, and the ultrasonic energy is concentratedly input to the cutting portion of the material to be cut by the cutter. Under the action of huge ultrasonic energy, this part softens and melts instantly, and the strength is greatly reduced. Cutting the material is achieved with a small amount of force.
The characteristics of the ultrasonic cutting machine do not require sharp edges, do not require a lot of pressure, and will not cause chipping or breakage of the cutting material.
The cutting blade is subjected to ultrasonic vibration, and the frictional resistance is particularly small, and the material to be cut is not easily adhered to the blade. It has obvious cutting effect on frozen, viscous and elastic materials. It is especially effective for cutting food, rubber or inconvenient objects.
At the same time of cutting, the cutting part has a fusion. The cutting site is perfectly sealed to prevent loose tissue (such as textile material flash). The use of ultrasonic cutting machines can also be extended, such as digging holes, shovel digging, scraping paint, engraving, slitting, etc.
Distinguishing traditional cutting
Ultrasonic cutting machine is a device that uses wave energy to cut and process. The biggest feature is that it does not use traditional cutting edge.
Conventional cutting uses a sharp-edged tool to press against the material being cut. The pressure is concentrated at the cutting edge, the pressure is very large, exceeding the shear strength of the material being cut, and the molecular bonding of the material is pulled apart and cut. Since the material is pulled hard by the strong pressure, the cutting edge of the cutting tool should be very sharp, and the material itself must withstand relatively high pressure. It is not good for soft and elastic materials, and it is more difficult for viscous materials.
