  • Detail

The difference between vacuum heat treatment and cold treatment of woodworking cutters in order to meet the strict requirements of international environmental protection standards, the circular economy concept of comprehensive utilization of wood and continuous supply of raw materials has promoted the rapid development of wood processing industry. Therefore, vacuum heat treatment and cryogenic technology have been developed. The technology has been applied to various products and will be presented in the upcoming 12th International Woodworking Machinery and furniture production equipment exhibition and the 12th International Furniture accessories, materials and wood products exhibition

it is understood that the tool vacuum heat treatment technology has a series of outstanding advantages: the vacuum heat treatment has the effect of anti-oxidation. The surface does not oxidize, decarbonize, and has the function of reducing rust in a spherical shape, which saves the rough machining process of the tool, saves the consumption of expensive tool steel and raw and auxiliary materials, saves processing time, and reduces the product cost; Vacuum heat treatment has the functions of vacuum degassing and degreasing without the danger of hydrogen embrittlement, preventing the surface embrittlement of refractory metal of tool material, improving the surface purity of tool material, improving the fatigue strength, plasticity, toughness and corrosion resistance of tool, and improving the service life of tool; Vacuum heat treatment has small quenching deformation, which can reduce the existence of correction stress for conventional quenching deformation and reduce the possibility of blade fracture during use. The deformation of vacuum heat treatment blade is 12-110 times that of salt bath quenching, and it can be finely ground to the finished product without correction after quenching; The vacuum heat treatment process has good stability and repeatability. Once the process is determined, the heat treatment operation will run automatically as long as the process program is input. Avoid tool quality fluctuation caused by unstable conventional heat treatment process; Vacuum heat treatment consumes less power, and the power consumption is 80% of that of conventional heat treatment. The production cost is low, but the one-time investment cost is high; Vacuum heat treatment is safe, highly automated, and has a good working environment. It is pollution-free and pollution-free. It meets the requirements of cleaner production and continuous development of wire core preheating and cable core drying efficiency in China's industrial enterprises

the application of cryogenic technology in tool products evolved from the application of mold industry. Cryogenic and waste plastics may bear the brunt. Treatment is the same as heat treatment. It has a great relationship with material properties, treatment temperature and treatment speed. Different treatment methods have significantly different effects. Cryogenic technology is a process method to treat materials at temperatures below - 130 ℃. Cryogenic treatment can not only significantly improve the mechanical properties and service life of cutting tools, stabilize the size, improve uniformity and reduce deformation, but also be easy to operate, do not damage the workpiece, have no pollution, and have low cost. In 2017, the power batteries are mainly 3-yuan 111 and 523, which are of great help to improve the quality of cutting tools
