Ultrasonic Basic Structure And Classification Application

Date:Sep 03, 2019

The basic components are an ultrasonic transducer, a booster, a cutting blade (tool head), and a generator. The ultrasonic generator converts the commercial power into a high-frequency high-voltage alternating current and transmits it to the ultrasonic transducer. An ultrasonic transducer is actually equivalent to an energy conversion device that converts input electrical energy into mechanical energy, ie, ultrasonic waves. Its manifestation is that the transducer moves back and forth in the longitudinal direction. The frequency of the telescopic motion is equivalent to the frequency of the high frequency alternating current supplied by the generator. The role of the booster is to fix the entire ultrasonic vibration system and to amplify the output amplitude of the transducer. The cutting blade (tool head) further enlarges the amplitude on the one hand and focuses the ultrasonic wave. On the other hand, the ultrasonic wave is output, and the ultrasonic energy is concentratedly input to the cutting portion of the material to be cut by using a similar cutting edge of the cutting blade. Under the action of huge ultrasonic energy, this part softens and melts instantly, and the strength is greatly reduced. 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 a cutter and an anvil, and the ultrasonic cutter has two basic structures.

Depending on the location of the ultrasonic application, we can divide it into ultrasonic cutter cutting and ultrasonic cutting board cutting. The ultrasonic cutter cutting directly loads the ultrasonic energy onto the cutter, and the cutter becomes a cutter with ultrasonic waves. When cutting the material, the material is mainly softened and melted by the ultrasonic energy, and the cutting edge of the cutter only serves as the slit positioning, the ultrasonic energy output, and the separation material. This cutting method is suitable for cutting thick and long  materials that are inconvenient to set the cutting board. Ultrasonic cutting machine is suitable for: raw rubber cutting, pipe cutting, frozen meat, candy, chocolate cutting, printed circuit board, industrial, jewelry, plastic products processing, food processing, printing industry, automotive industry, natural fiber segmentation (divided into fine lines) synthetic fiber deep excavation (multilayer circuit cut) thin synthetic resin lacquer (suitable for large areas) All types of paper and base film origin or hand-held cutting machine and so on.
