The basic structure of ultrasonic cutting machine

Update:19 Sep 2017

   Ultrasonic cutting machine is the use of wave energy for cutting a class of equipment, its biggest feature is the cutting without cutting edge. Or, do not have the traditional sense of the edge. The traditional cutting is the use of a tool with a sharp edge, pressed to the cutting material. This pressure is concentrated in the edge of the mouth, the pressure is very large, more than the shear material shear strength, material molecules were opened, was cut off. As the material is a strong pressure to pull hard, so cutting tool edge should be very sharp, the material itself to bear the relatively large pressure. Soft, flexible material cutting effect is not good, more difficult to sticky material.
   
The basic structure is the ultrasonic transducer, horn, cutting knife (tool head), drive power. Ultrasonic drive power will be converted into high-frequency high-voltage AC current, lost to the ultrasonic transducer. Ultrasonic transducer is actually equivalent to an energy conversion device, it can enter the input energy into mechanical energy, that is, ultrasonic waves. Its manifestation is the transducer in the longitudinal back and forth telescopic movement. The frequency of the telescopic motion is equivalent to the frequency of the high frequency AC current supplied from the drive power supply. The effect of the horn is to fix the entire ultrasonic vibration system, and the other is to amplify the output amplitude of the transducer. The cutter (tool head) further amplifies the amplitude on one hand, focusing the ultrasound. On the other hand is the output of ultrasonic waves, the use of cutting knife similar to the edge, the ultrasonic energy concentrated input to the cutting material cutting parts. The site in the huge ultrasonic energy under the effect of instant softening, melting, strength greatly reduced. At this point, as long as the application of a small cutting force, you can achieve the purpose of cutting materials. Similar to the conventional cutting, the basic components required are the cutter and the cutting board, and the ultrasonic cutting machine is also composed of two basic structures. Depending on the location of the ultrasonic application, we may wish to divide it into ultrasonic cutter and ultrasonic cutting board cutting machine. Ultrasonic cutting knife cutting machine is directly to the ultrasonic energy loaded on the cutter, the cutter becomes a knife with ultrasonic. In the cutting material, the material is mainly softened and melted by the ultrasonic energy, the cutting edge of the knife is only to play the slit positioning, ultrasonic energy output, the role of separation materials. This cutting method is suitable for rough, thick, long and so inconvenient to set the cutting of the material of the cutting board. Ultrasonic cutting machine for: such as rubber production of raw rubber cutting, pipe cutting, frozen meat, candy, chocolate cutting, printed circuit boards, industrial, jewelry industry, plastic products processing, food processing, printing industry, the automotive industry Natural fiber segmentation (separable line), synthetic fiber deep excavation (multi-layer circuit cut), plastic shell processing, thin artificial resin paint (for large area) all types of paper and the bottom film origin (China) or hand Type cutting machine and so on.
