Axle type component surface strengthening method and strengthening effect detecting method

Abstract

The invention discloses an axle type component surface strengthening method and a strengthening effect detecting method. The surface strengthening method comprises the steps that an axle type component is pre-machined, and the axle type component with the preset size is obtained; a rolling cutter with a wheel is arranged at the position of a machine tool cutter rest; a lubricating agent is sprayedto a to-be-rolled part of the axle type component; and profiling rolling is conducted on the axle type component according to the structure compiling numerical control program of the axle type component. According to the axle type component surface strengthening method and the strengthening effect detecting method, the rolling operation automatic control is achieved, indeterminacy of manual control is avoided, and the labor intensity is lowered; and the hardness of the axle type component formed through rolling is improved, roughness is lowered, the surface quality is good, abrasion resistance and fatigue resistance are enhanced, and accordingly the service life of the axle type component is prolonged. According to the axle type component strengthening effect detecting method, the detection index and the reference value are provided, and whether the strengthening effect meets the usage requirement or not is conveniently judged.

Description

technical field [0001] The invention relates to the technical field of metal processing, in particular to a method for strengthening the surface of shaft parts and a method for detecting the strengthening effect. Background technique [0002] Rolling strengthening on the surface of shaft parts can improve its surface quality, improve surface wear resistance and fatigue resistance, especially for railway axle bearing seats, gearbox seats and transition arcs, which can effectively prolong their service life. [0003] At present, the rolling of railway axles is mainly carried out manually by skilled operators, and the feeds in the diameter direction and the length direction are all manually coordinated and controlled manually, which is not easy to coordinate and control. Especially for the arc parts, it is very likely that the rolling force will be unstable, resulting in local stress concentration, which will bring hidden dangers to the use of the axle. There is no effective me...

[0003] At present, the rolling of railway axles is mainly carried out manually by skilled operators, and the feeds in the diameter direction and the length direction are all manually coordinated and controlled manually, which is not easy to coordinate and control

Especially for the arc parts, it is very likely that the rolling force will be unstable, resulting in local stress concentration, which will bring hidden dangers to the use of the axle. There is no effective method for the quantitative control of the rolling process of the axle and the quantitative detection after rolling, and the rolling effect cannot be guaranteed.
