Problems solved by technology

[0002] At present, the foreign advanced RV manufacturing technology has removed all the wooden materials on the car, and the main material of the RV is composite, thermoplastic and light-weight composite structural materials. This type of composite material is composed of two or more The different materials are mixed together, and the laying direction and layering of the fibers are different, so it poses a higher challenge to the processing. Traditional woodworking tools are prone to the following problems during processing: rapid tool wear, excessive burrs, and material layering , the remaining fibers are not cut off, the processing is overheated, the service life is short, the production efficiency is low, the production accuracy is not high, etc.

Abstract

The invention relates to a positioning double-section cutter which is high in production efficiency, not prone to wear and long in service life. The positioning double-section cutter comprises a cutter body. The cutter body comprises a first base body outer cylinder, a positioning cylinder, a second base body outer cylinder and a cutter handle in sequence. The first base body outer cylinder is provided with a first cutting blade. The second base body outer cylinder is provided with a second cutting blade. The direction of the cutting edge of the first cutting blade is opposite to that of the cutting edge of the second cutting blade. The length of the first base body outer cylinder is the same as that of the second base body outer cylinder. The size and shape of the first cutting blade are the same as those of the second cutting blade. The excircle diameter of the positioning cylinder is 0.5-0.8 mm larger than the cutting circle diameter of the second cutting blade. The relief angles of the first cutting blade and the second cutting blade are arc relief angles. According to rake faces of the first cutting blade and the second cutting blade, the blade thickness of the cutter point portions is larger than that of the blade roots. The cutter body is further provided with a chip groove.

Description

technical field [0001] The invention relates to a non-metal material cutting tool mainly used in the cutting process of caravan materials, in particular to a double-section knife with positioning. Background technique [0002] At present, the foreign advanced RV manufacturing technology has removed all the wooden materials on the car, and the main material of the RV is composite, thermoplastic and light-weight composite structural materials. This type of composite material is composed of two or more Different materials are mixed together, and the laying direction and layering of fibers are different, so it poses a higher challenge to processing. Traditional woodworking tools are prone to the following problems during processing: rapid tool wear, excessive burrs, and material layering , the remaining fibers are not cut off, processing overheating, short service life, low production efficiency, low production accuracy and other issues. Contents of the invention [0003] The...
