Ultrasonic cutting machine is a type of equipment that uses wave energy for cutting. Its biggest feature is that it does not need a cutting edge. In other words, no traditional cutting edge is needed. Traditional cutting is to use a knife with a sharp edge to press against the material being cut. This pressure is concentrated at the edge of the blade, and the pressure is very large, exceeding the shear strength of the material being cut, and the molecular bond of the material is pulled apart and cut off. Because the material is pulled apart by strong pressure, the cutting edge of the cutting tool should be very sharp, and the material itself must withstand relatively large pressure. It is not good for cutting soft and elastic materials, and it is more difficult for sticky materials.
The basic structure is an ultrasonic transducer, horn, cutter (tool head), and drive power. The ultrasonic drive power converts the city power into high-frequency high-voltage alternating current, which is transmitted to the ultrasonic transducer. Ultrasonic transducer is actually equivalent to an energy conversion device, it can convert the input electrical energy into mechanical energy, that is, ultrasound. Its manifestation is that the transducer moves back and forth in the longitudinal direction. The frequency of the telescopic movement is equal to the frequency of the high-frequency alternating current supplied by the driving power supply. The role of the horn is to fix the entire ultrasonic vibration system, and second to amplify the output amplitude of the transducer. On the one hand, the cutter (tool head) further amplifies the amplitude and focuses the ultrasound. On the other hand, it outputs ultrasonic waves, and uses a similar edge of the cutting blade to concentrate the ultrasonic energy into the cutting site of the material to be cut. Under the action of huge ultrasonic energy, this part instantly softens and melts, and its strength drops greatly. At this time, as long as a small cutting force is applied, the purpose of cutting the material can be achieved. Similar to conventional cutting, the basic components required are the cutter and the cutting board, and the ultrasonic cutting machine also has two basic structures.
