Ultrasonic cutting equipment is an ultrasonic equipment specifically designed for cutting, the principle is completely different from traditional cutting. The ultrasonic cutting machine uses the energy of ultrasonic waves to melt the local heating of the cutting material, so as to achieve the purpose of cutting the material. The characteristics of ultrasonic cutting machine do not require sharp blades, do not require great pressure, and will not chip and break the cutting material. The cutting knife is doing ultrasonic vibration, the friction resistance is particularly small, and the cutting material is not easy to stick to the blade. The cutting effect on frozen, viscous and elastic materials is obvious. Cutting objects such as food, rubber or inconvenient to add pressure is particularly effective. At the same time as cutting, the cutting site has a melting effect. The cutting part is perfectly edged to prevent loose microstructure of the cut material (e.g. textile material flying edge). The use of ultrasonic cutting machine can also be expanded, such as digging holes, shovel digging, scraping paint, engraving, slitting, etc.
The difference between the traditional cutting ultrasonic cutting machine is the use of wave energy for cutting processing equipment, the biggest feature is that the traditional edge is not used. Ultrasonic rubber cutting knives Traditional cutting uses a knife with a sharp edge to press against the material being cut. The pressure is concentrated at the edge, the pressure is very large, exceeding the shear strength of the material being cut, and the molecular binding of the material is pulled apart and cut. Since the material is pulled apart by a strong pressure force, the cutting tool edge should be very sharp, and the material itself must withstand relatively large pressure. The cutting effect of soft and elastic materials is not good, and there is a great advantage of ultrasonic cutting that is more difficult for viscous materials, that is, it has a melting effect in the cutting site at the same time as cutting, and the cutting part is perfectly edged, which will not cause the textile material to fly. The use of ultrasonic cutting machines can also be expanded, such as digging holes, shovel digging, scraping paint, engraving, etc.
The basic composition of the ultrasonic cutting machine is an ultrasonic transducer, a luffing rod, a cutting knife (tool head), and a driving power supply. The ultrasonic drive power supply converts the mains electricity into high-frequency and high-voltage AC current, which is transmitted to the ultrasonic transducer. The ultrasonic transducer is actually equivalent to an energy conversion device, which can convert the input electrical energy into mechanical energy, that is, ultrasonic. It is manifested in the longitudinal telescopic movement of the transducer in a longitudinal and retractable motion. The frequency of the telescopic motion is equivalent to the frequency of the AC current supplied by the drive power supply. The role of the amplitude changing rod is to fix the entire ultrasonic vibration system, and the second is to amplify the output amplitude of the transducer. On the one hand, the cutting knife (tool head) further amplifies the amplitude and focuses on the ultrasonic waves. On the other hand, the output ultrasonic wave uses the similar edge of the cutting knife 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, so as to achieve the purpose of cutting materials.
