Description

Technical Field

[0001] The invention relates to the technical field of carbon-carbon composite material cutting, in particular to a carbon-carbon composite material cutting and processing equipment. Background Art

[0002] Carbon-carbon composites are composite materials composed of carbon fibers and matrix carbon. The carbon fibers play a reinforcing role, and the matrix carbon plays a bonding role. Since carbon fibers have the characteristics of high strength, high modulus, and low density, carbon-carbon composites have the characteristics of high strength, high modulus, low density, high temperature resistance, oxidation resistance, and corrosion resistance. According to different classification standards, carbon-carbon composites can be divided into different types, which are mainly used in mechanical seals, aerospace and other fields. Some of the carbon-carbon composites need to be split by cutting devices during production.

[0003] However, the structure of the existing carbon-carbon composite material cutting device is too simple. When the carbon-carbon composite material is cut on the cutting table of the cutting device, the carbon-carbon composite material needs to be fed manually, which is less practical. In addition, the cut carbon-carbon composite material also needs to be collected manually, which affects the production efficiency of the carbon-carbon composite material. Secondly, when the existing clamping and positioning device for cutting carbon-carbon composite materials is used to cut and position the longer carbon-carbon composite material, due to the longer carbon-carbon composite material, it is easy to cause the rear end of the carbon-carbon composite material to warp up during cutting, resulting in cutting failure and waste of carbon-carbon composite material.
