Problems solved by technology
Stainless steel is generally used as the material, and there are some ceramic knives at present, but ceramic knives are afraid of falling, so the mainstream products are still stainless steel
[0007] At present, in the production process of many knives, in order to pay attention to speed, the produced knives have more impurities and lower purity, which seriously affects the hardness of the knives, thereby affecting the service life of the knives. Therefore, an improved technology is urgently needed to solve the problem. There is this problem in the technology

The invention discloses a forging process of a low impurity steel tool. The forging process comprises the following steps: selecting materials according to drawings; rapid heating; rotating forging 3-5 times; cooling, heating, adding borax and continuing forging; twisting forgings; cooling, heating, adding borax and fine forging; conducting heat treatment, grinding and polishing. According to theforging process, hammering and forging are conducted for multiple times and then combined with borax to forge internal impurities out, then rotating is conducted through a stirring rod, and the impurities inside castings can also be separated. Finally, the castings are formed by a small air hammer forging machine. A tool obtained from the forging method has pure composition and few impurities, andthe tool with high quality can be forged.
Description
technical field [0001] The invention relates to the technical field of cutting tool forging technology, in particular to a forging technology of low-impurity steel cutting tools. Background technique [0002] Forging is the collective name of forging and stamping. It is a forming process that uses the hammer, anvil, punch or through the die of the forging machine to exert pressure on the blank to cause plastic deformation to obtain the required shape and size of the workpiece. . [0003] In the forging process, the billet undergoes obvious plastic deformation as a whole, and there is a relatively large amount of plastic flow; in the stamping process, the billet is mainly formed by changing the spatial position of each part area, and there is no large-distance plastic flow inside it. Forging is mainly used to process metal parts, and can also be used to process some non-metals, such as engineering plastics, rubber, ceramic blanks, brick blanks, and composite materials. [0...
