Abstract

The invention discloses a heat treatment technology for automobile transmission gears. The heat treatment technology comprises a heat treatment container which is indispensable for heat treatment, heat treatment liquid and heat treatment operation technological procedures, wherein the heat treatment container comprises a heat treatment tank, heat treatment tank temperature control devices, the heat treatment liquid, a material supplement device, tank liquid observation sensors, an oil fume treatment device and a heat treatment liquid circulation device; the heat treatment liquid circulation device comprises an adjustable sprayer for spraying the heat treatment liquid; the sprayer can spray the heat treatment liquid on the to-be-treated automobile transmission gears; and the material supplement device is provided with a preparation material. By adopting the heat treatment technology, each technological detail of the heat treatment can be perfectly controlled; values between practical heat treatment technology and ideal technology can be adjusted and corrected in real time; the heat treatment is stable in quality, and is high-efficient and energy-saving; pollution is reduced; environment protection is promoted; and heat treatment cost can be reduced.

Description

technical field [0001] The invention relates to the field of gear heat treatment, in particular to a heat treatment process for an automobile transmission gear. Background technique [0002] Quenching is a part of the heat treatment process. The steel is heated above the phase transition temperature, and after a certain period of time, it is rapidly cooled in a cooling medium to obtain a martensitic structure. The quenching process is directly related to the service performance and life of the workpiece, and the selection of quenching medium is the key to improving the quality of the workpiece. Quenching oil is a process oil for quenching, used as a cooling medium, which can reduce the cracking and deformation of the workpiece and enhance the hardness of the workpiece. Quenching oil has been used under harsh conditions of high temperature and continuous operation for a long time, requiring the oil to have good anti-oxidation, anti-thermal decomposition and anti-aging proper...
