      Ultrasonic cutting machine

      1, ultrasonic cutting machine introduction The principle of Guosheng ultrasonic cutting machine is completely different from the traditional cutting. It uses the energy of ultrasonic waves to melt the local heating of the material to be cut, so as to achieve the purpose of cutting the material. Therefore, the ultrasonic cutting does not require a sharp cutting edge, nor does it require a large pressure, and does not cause chipping or breakage of the material to be cut. At the same time, since the cutting blade is subjected to ultrasonic vibration, the frictional resistance is particularly small, and the material to be cut is not easily adhered to the blade. This is particularly effective for cutting viscous and elastic materials, frozen materials such as food, rubber, etc., or objects that are inconvenient to apply pressure. Ultrasonic cutting

      1. Introduction of ultrasonic cutting machine



      The principle of ultrasonic cutting machine is different from traditional cutting. It uses the energy of ultrasonic wave to melt the cutting material by local heating, so as to achieve the purpose of cutting material. Therefore, ultrasonic cutting does not need sharp edges, nor does it need a lot of pressure to reduce the edge collapse and damage of the material being cut. At the same time, due to the ultrasonic vibration of the cutting tool, the friction resistance is small, and the cutting material is not easy to adhere to the blade. This is better for cutting viscous and elastic materials, frozen materials, such as food, rubber, etc., or objects with inconvenient pressure. Ultrasound cutting also has a great advantage, that is, it can melt at the cutting site while cutting. The cutting part is completely and beautifully edged, which can reduce the looseness of the cut material organization (such as textile material flying edge). The use of ultrasonic cutting machine can also be extended, such as hole digging, shovel digging, paint scraping, sculpture, slicing and so on.


      2. Characteristics of ultrasonic cutting machine


      Guosheng Ultrasound Cutting Machine is a kind of equipment which uses wave energy to cut. Its characteristic is that cutting does not need cutting edge, or traditional cutting edge. Traditionally, cutting tools with sharp edges are used to press the material to be cut. When the pressure is concentrated at the edge, the pressure is very high, which exceeds the shear strength of the material being cut. When the molecular bond of the material is pulled apart, it is cut off. Because the material is pulled apart by greater pressure and hardness, the cutting tool edge should be very sharp, and the material itself has to bear greater pressure. For soft and elastic materials, the cutting effect is not good, and for viscous materials, it is difficult.


      3. Basic structure of ultrasonic cutting machine


      The basic structure of Guosheng ultrasonic cutting machine is ultrasonic transducer, horn, cutting knife (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 ultrasonic energy, this part softens and melts instantaneously, 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. Similar to conventional cutting, the basic components required are cutting knives and cutting boards, and the ultrasonic cutting machine has two basic structures.


      4. Classification and application of ultrasonic cutting machine


      According to the different position of ultrasound, we may as well divide it into ultrasonic cutter cutter and ultrasonic anvil cutter. Ultrasound cutter is a cutter which loads the ultrasonic energy directly on the cutter, and the cutter becomes a cutter with ultrasonic wave. When cutting material, the material is mainly softened and melted by ultrasonic energy. The cutting edge of the cutter only plays the role of seam location, ultrasonic energy output and separating material. This cutting method is suitable for cutting materials with rough, thick and long chopping boards which are not convenient to set. Such as raw rubber slicing, pipe cutting, frozen meat, candy, chocolate cutting, printed circuit board, or hand-held cutting machine. The basic structure of the ultrasonic anvil cutting machine is similar to that of the ultrasonic cutter cutting machine, except that the output part of the ultrasonic wave is not the cutter, but a standard ultrasonic plane die. Here, the die is equivalent to an anvil. It's just an anvil for ultrasonic vibration. Cutting knives are still available in many traditional shapes, but the requirement for sharp edges is reduced and the life of cutting knives is longer. Because of the role of ultrasound, the traditional cutting blade also allows for great changes. Typically, the cutter is transformed into a cylindrical wheel with a raised pattern, commonly known as a flower wheel. The raised part corresponds to the cutting edge of the cutter, and the cut material passes between the flower wheel and the ultrasonic cutting board. This combination can cut a lot of patterns, low cost and high efficiency. This cutting method is suitable for thin sheet material cutting, such as trademark, garment lace, cloth cutting, decorative bead cutting, natural fibers, synthetic fibers, non-woven fabrics, artificial resin, paper, film cutting, segmentation and so on.
