Description

Ultrasonic wave transduction cutting knife suitable for various types of cutting

Technical Field

The invention belongs to the technical field of ultrasonic cutters, and particularly relates to an ultrasonic transduction cutter suitable for various types of cutting.

Background

An ultrasonic cutting machine is an apparatus that utilizes wave energy to perform cutting. It features no need of sharp. Or, instead of, a conventional blade. The conventional cutting method is to press the material to be cut with a cutter having a sharp cutting edge. The pressure is concentrated at the cutting edge and is high, exceeding the shear strength of the material being cut. The molecular bonds of the material are pulled apart and cut. Since the material is difficult to pull apart under strong pressure, the cutting edge of the knife should be very sharp and the material itself should be subjected to great pressure. For soft and elastic materials, the cutting is not good, while for viscous materials the cutting is more difficult.

The basic structure of the ultrasonic cutting machine comprises an ultrasonic transducer, a horn, a cutter and a driving power supply. The ultrasonic driving power supply converts the power supply into high-frequency high-voltage alternating current and transmits the high-frequency high-voltage alternating current to the ultrasonic transducer. The ultrasonic transducer is actually equivalent to an energy converter which can convert the input electric energy into mechanical energy, i.e., ultrasonic waves. It behaves as a longitudinal back and forth movement of the transducer. The frequency of the telescopic motion is equal to the frequency of the high-frequency alternating current provided by the driving power supply. The function of the amplitude transformer is to fix the whole ultrasonic vibration system and amplify the output amplitude of the transducer. In one aspect, the tool further amplifies the amplitude and focuses the ultrasound. On the other hand, ultrasonic energy is input to the cutting portion of the material using a similar cutting edge of the cutter. Under the action of huge ultrasonic energy, the part is instantly softened and melted, and the strength is greatly reduced. In this case, the object of cutting the material can be achieved by applying a small cutting force. Similar to conventional cutting, the essential parts required are a cutter and an anvil.

Ultrasonic wave transduction cutting knife can cut the material of different grade type (crude rubber cutting, the tubular product cutting, the frozen meat, the candy, chocolate cutting, printed circuit board, industry, the jewelry industry, plastic products processing, food processing, printing industry, the automobile industry, natural fiber cuts apart, synthetic fiber digs deeply, plastic housing processing, thin synthetic resin contains all kinds of paper of paint and backer film), because the difference of cutting material, thereby need select the use that the tool bit that corresponds carries out the adaptation according to the material, and avoid interference such as cross infection, all need carry out the frequent switching of tool bit, but some materials belong to frequent cutting and use, it is comparatively troublesome to change it because other materials of cutting occasionally at every turn, thereby need one set can carry out the equipment that multiple type material all can cut.
