Little knowledge of ultrasonic cutting machine
Ultrasonic cutting machine is a special ultrasonic cutting equipment, which is one of the important categories of ultrasonic applications. The principle is completely different from traditional cutting. Ultrasonic cutting machine uses ultrasonic energy to melt the part of the material to be cut, so as to achieve the purpose of cutting the material.
1 The feature of the ultrasonic cutting machine is that it does not need sharp blades, does not require a lot of pressure, and will not cut the edges of the material and cause damage.
The cutting knife is ultrasonically vibrated, the friction resistance is very small, and the material being cut is not easy to stick to the blade. For frozen, viscous and elastic materials, the cutting effect is obvious. Especially suitable for cutting food, rubber or objects that are inconvenient to pressurize.
2 While cutting, the cut part has a fusion effect. The edge of the cutting part is completely sealed to prevent the structure of the material being cut from loosening (such as the flashing of textile materials). The application range of the ultrasonic cutting machine can also be expanded, such as digging, digging, scraping paint, engraving, and cutting.
Ultrasonic cutting machine is a kind of equipment that uses wave energy for cutting processing. Its characteristic is that it does not use traditional sharp-edged knives. Traditional cutting is to use a sharp tool to press down the material to be cut. The pressure is concentrated on the blade. The pressure is very high, exceeding the shear strength of the material being cut. The molecular bonds of the material are pulled apart and severed. Since the material is difficult to be pulled apart under strong pressure, the cutting edge of the tool should be very sharp, and the material itself should withstand greater pressure. For soft and elastic materials, the cutting effect is not good, and for sticky materials, it is more difficult to cut.
According to the ultrasonic cutting machine, the cutting method can be divided into: knife cutting machine and chopping board cutting machine. These two cutting methods are suitable for different process conditions and cutting objects.
The tool-type cutting machine loads ultrasonic waves on the cutting tool, so that the cutting tool generates ultrasonic vibration to achieve the cutting effect.
This cutting method is suitable for: raw rubber cutting, pipe cutting, frozen meat, candy, chocolate cutting, printed circuit boards, natural fiber segmentation, synthetic fiber deep digging, plastic shell processing, synthetic resin coating, hand-held cutting, etc.
The cutting board machine loads the ultrasonic vibration on the cutting bottom mold. The bottom mold is like a cutting board used in daily life. The cutting board produces ultrasonic vibration, which can also achieve the cutting effect. There is no need to change tools, and ordinary tools can be used.
