Abstract

The invention discloses a local surface heat treatment process for bar parts, and belongs to the technical field of heat treatment. The local surface heat treatment process comprises the following steps that S1, an industrial personal computer controls a high-frequency quenching machine to locally heat the parts, and the power on the high-frequency quenching machine is manually adjusted; and S2, an electromagnet is controlled through a PLC control program to attract the parts for heat treatment operation, resistance on the high-frequency quenching machine is adjusted, current is changed, and therefore the attraction force of the electromagnet is changed. According to the process, the electromagnet is mainly used for attracting the bar parts, the attraction force of the electromagnet is changed by adjusting the resistance of the high-frequency quenching machine and changing the current of the high-frequency quenching machine, and in addition, a direct-current adjustable rotating motor is arranged, so that the bar parts are subjected to heat treatment under the rotating condition; and in the atomization spraying and nitrogen bubble state, the contact time of oil and the locally heated bar parts is prolonged, so that the quenching effect is improved, the hardness of the bar parts is improved, the wear resistance is improved, and the service life is prolonged.

Description

technical field [0001] The invention relates to a partial surface heat treatment process for bar-like parts, and belongs to the technical field of bar-like heat treatment. Background technique [0002] High-frequency quenching is mostly used for surface quenching of industrial metal parts. It is a metal heat treatment method that generates a certain induced current on the surface of the workpiece, rapidly heats the surface of the part, and then rapidly quenches it. Induction heating equipment, that is, equipment for induction heating of workpieces for surface hardening. [0003] However, the current heat treatment process is not effective, especially the partial surface heat treatment, which will result in unqualified product quality, such as low hardness and wear resistance, which will directly affect the service life. Contents of the invention [0004] The present invention is aimed at the technical problem mentioned in above-mentioned background technology, and adopts ...
