Description

Technical Field

[0001] The utility model belongs to the field of ultrasonic technology, and in particular relates to a novel ultrasonic rubber cutting device. Background Art

[0002] Ultrasonic rubber cutting equipment is an electromechanical device that uses wave energy for cutting. Its notable feature is that it does not require a cutting edge, or in other words, does not require a cutting edge in the traditional sense. As we all know, traditional cutting uses a tool with a sharp cutting edge to press against the material to be cut. This pressure is concentrated at the cutting edge, resulting in a very high pressure. When the pressure exceeds the shear strength of the material to be cut, the molecular bonds of the material are pulled apart, thereby achieving material cutting. However, since the material is pulled apart by strong pressure, this requires that the cutting tool edge should be very sharp, and the material itself must withstand relatively large pressure. This cutting method is often not effective for soft and elastic materials, and is even more difficult for sticky materials.

[0003] At present, the traditional rubber cutting technology requires lubrication of the rubber during cutting, which results in slow cutting speed, large incisions that produce a lot of dust and debris, uneven cut surfaces, and sticky knives. In addition, many companies are still using traditional manual cutting methods, which not only cannot meet production needs, but also poses certain safety hazards. Therefore, for rubber products, cold cutting is more suitable than hot cutting. Cold cutting has the characteristics of low heat generation, low thermal deformation, less dust during cutting, and the cross section will not age and crack due to high temperature. It is particularly suitable for the cutting technology field of soft products such as rubber. Utility Model Content
