AI Technical Summary

Problems solved by technology

High-carbon steel has low hardness and is brittle, and its wear resistance is poor as a blade material. Therefore, high-carbon steel fixed knives are afraid of falling and need lubricating oil for lubrication. The heads of high-carbon steel electric push scissors need to be ground 4-5 times a year. Even more times, but there are very few masters who grind electric clipper heads professionally, which requires higher costs, and frequent replacement will also bring higher costs
Ceramic materials have good wear resistance, but the disadvantage is that they are more brittle, so they are only suitable for fixed knives with smaller thickness, not suitable for fixed knives with larger thickness, and not suitable for the overall fixed knives to use ceramic materials
Tungsten steel has a series of excellent properties such as high hardness, wear resistance, good strength and toughness, heat resistance, and corrosion resistance. It can be used as an ideal material for electric push scissors and fixed knives. Made of tungsten steel, the production cost is high

Description

technical field [0001] The invention relates to a hairdressing appliance, and provides a fixed knife sub-piece of an electric clipper head and a fixed knife of the electric clipper head using the fixed knife sub-piece of the electric clipper head. Background technique [0002] Electric clippers are commonly used hair trimming tools in daily life, and generally include an electric clipper head and an electric clipper body. The electric clipper head is the main functional component of the electric clipper, mainly including the fixed knife, the moving knife and other accessories. At present, most of the electric scissor heads on the domestic and foreign markets use high-carbon steel as the material for the fixed knife and the moving knife. A very small number of high-priced electric scissor heads use tungsten carbide or ceramic materials, and ceramic materials are currently only used As a knife material. High-carbon steel has low hardness and is brittle. As a blade material, ...
