The principle of ultrasonic cutting blade replacement

Ultrasonic cutting knife utilizes the energy of ultrasonic waves to cut the local vibration of the material being cut, thereby achieving the purpose of material cutting. Traditional cutting uses a cutting tool with a sharp edge to press against the material being cut. This pressure is concentrated at the edge, and the pressure is very high, exceeding the shear strength of the material being cut. The molecular binding of the material is pulled apart, and it is cut off. Ultrasonic cutting has a great advantage, which is that it has a fusion effect at the cutting site while cutting. The cutting site is perfectly sealed, which can prevent the loose tissue of the cut material. Therefore, ultrasonic cutting does not require sharp edges, does not require a lot of pressure, and will not cause edge collapse or damage to the cut material. When the cutting blade vibrates with ultrasonic waves, the frictional resistance is particularly small. The high-frequency signals generated by the ultrasonic vibration system are transmitted to the ultrasonic transducer, converted into sound waves, and transmitted to the cutting edge of the ultrasonic cutting blade through the amplitude converter. The sound wave energy is converted into mechanical vibration energy to achieve the function of cutting vibration. By using the cutting edge of the cutting blade, the ultrasonic energy is concentrated and input to the cutting part of the material being cut. Under the action of enormous ultrasonic energy, this area instantly softens and melts, resulting in a decrease in strength. At this time, as long as a small cutting pressure is applied, the material cutting purpose can be achieved.
