Abstract

The invention relates to a precise heat treatment method of a high-precision elastic element. In the invention, quenching is carried out by adopting a fluidized particle furnace and elastic element quenching treatment equipment, wherein graphite particles are used as a heating medium and optimized design is carried out on the quenching temperature, the heat preservation time and the cooling manner so that the non-oxidation quenching treatment of the high-precision elastic element is realized and the surface quality and the size precision of the high-precision elastic element are improved; according to the quenching rigidity of the high-precision elastic element, proper technological parameters are selected to carry out tempering treatment; and loading ageing treatment is conducted to the element by adopting elastic element loading treatment equipment so that the stress relaxation property of the elastic element is improved, the stress in the winding process is reduced and the micro-yield strength is effectively improved. Through the heat treatment method of the invention, the high-precision elastic element is free of oxidation on the surface, free of deformation on the size and stable in mechanical property after the quenching, and the reliability and the quality of the heat treatment of the high-precision elastic element are improved.

Description

technical field

[0001] The invention relates to a precision heat treatment technology for elastic components, in particular to a precision heat treatment method for high-precision elastic components. Background technique

[0002] High-precision elastic elements are commonly used components in spacecraft structures and mechanisms, machinery, and electronic products. After forming, elastic elements need to be strengthened by heat treatment to meet their technical indicators such as hardness, strength, and elasticity. The dimensional deviation of the high-precision elastic element is small, and the oxidation, thermal stress, tissue stress, etc. generated during the heat treatment process can easily cause the dimensional tolerance of the elastic element; the micro-yield deformation of the elastic element when used under high stress conditions affects its mechanical properties .
