What are the advantages of ultrasonic cutting equipment?
Ultrasonic cutting machine is a kind of equipment that uses wave energy for cutting. Its biggest feature is that cutting does not use the cutting edge in the traditional sense.Conventional cutting uses a sharp-edged tool to press against the material being cut.This pressure is concentrated at the cutting edge, and the pressure is very large, exceeding the shear strength of the material being cut. The molecular combination of the material is pulled apart and cut.Since the material is pulled hard by strong pressure, the cutting edge of the cutting tool should be very sharp, the material itself must withstand relatively large pressure, the cutting effect on soft and elastic materials is not good, and the viscous material is more difficult.Ultrasonic cutting also has a great advantage, that is, it has a fusion at the cutting part while cutting, and the cutting part is perfectly sealed to prevent the looseness of the material to be cut (such as the flash of textile material).
Ultrasonic cutting machine can be used in a wide range of applications, such as raw rubber cutting, pipe cutting, frozen meat, candy, cake cutting, industrial, jewelry, plastic products processing, food processing, printing industry, automotive industry.Fiber splitting (dividable fine lines), synthetic fiber deep digging (multi-layer circuit cutting), plastic casing processing, thin synthetic resin lacquer (suitable for large areas) All types of paper and base film origin (China) or hand-heldCutting machine and so on.The use of ultrasonic cutting machines can also be extended, such as digging holes, shovel digging, scraping paint, engraving, slitting and so on.
The basic composition of the ultrasonic cutting machine is the ultrasonic transducer, horn, cutting tool (tool head), driving power supply. Ultrasound driving power converts municipal electricity into high frequency and high voltage AC current, which is transmitted to the ultrasonic transducer. Ultrasound transducer is actually equivalent to an energy converter device, which can convert the input electric energy into mechanical energy, that is, ultrasound. Its manifestation is that the transducer moves back and forth longitudinally. The frequency of the telescopic motion is equal to the frequency of the high frequency AC current supplied by the driving power supply. The function of the horn is to fix the whole ultrasonic vibration system and to amplify the output amplitude of the transducer. On the one hand, the cutting tool (tool head) further enlarges the amplitude and focuses on the ultrasonic wave. On the other hand, the output of ultrasonic wave, using the similar cutting edge of the cutting tool, will concentrate the ultrasonic energy into the cutting part of the material being cut. Under the action of huge ultrasonic energy, this part instantaneously softens and melts, and its strength decreases greatly. At this time, as long as a very small cutting force is applied, the purpose of cutting materials can be achieved.
