vacuum heat treatment technology and cold treatment of woodworking tools
The difference between vacuum heat treatment technology and cold treatment of woodworking tools
In order to meet the strict requirements of international environmental protection scale, the economic concept of comprehensive utilization of wood and continuous supply of raw materials has promoted the rapid development of wood processing industry. Thus the vacuum heat treatment and cryogenic technology were developed. The technology has been used in various products, and will appear in the upcoming 12th international woodworking machinery and furniture production equipment expo, the 12th international furniture accessories, materials and wood products expo.
It is understood that the tool vacuum heat treatment technology has a series of advantages: vacuum heat treatment has anti-oxidation. The surface does not oxidize, does not decarbonize, and has the reduction derusting function, saves the cutting tool rough processing procedure, may save the expensive cutting tool steel and the original auxiliary material consumption, saves the processing time, reduces the product cost; Vacuum heat treatment has the function of vacuum degassing, degreasing and no hydrogen embrittlement danger, preventing the surface embrittlement of the refractory metal of the tool material, improving the purity of the tool material surface, improving the strength of the tool fatigue, plasticity, toughness and corrosion resistance, and improving the service life of the tool; Vacuum heat treatment has small quenching deformation, which can reduce the existence of correction stress of conventional quenching deformation, and reduce the possibility of fracture of the blade during the use of the process. The deformation of the blade of vacuum heat treatment is 12-110 after salt bath quenching, which can be refined and machined to finished products without correction in general after quenching. The vacuum heat treatment process has good stability and repeatability. Once the process is determined, as long as the process program is entered, the heat treatment operation will be automatically run. Avoid tool quality fluctuation caused by normal heat treatment process; Vacuum heat treatment consumes less electricity, the energy consumption is 80% of the conventional heat treatment, the production cost is low, but the one-time investment cost is large; Vacuum heat treatment operation safety, high degree of automation, good working environment, no pollution and pollution-free, in line with China's industrial enterprises clean production and sustainable development requirements.
The application of cryogenic technology in tool products is evolved from the application of mold industry. Cryogenic treatment is the same as heat treatment, which is closely related to material properties, treatment temperature and treatment speed. Different treatment methods have significantly different effects. Cryogenic technology is on the material in the below - 130 ℃ for processing technology of a kind of method, cryogenic treatment can not only obvious progress on the mechanical function and tool life, not size, improve the average resistance, reduce the deformation, and the manipulation is simple, does not destroy the artifact, no pollution, low capital, the progress of the quality of the cutting tool has a lot of help.
