Abstract

The invention relates to a site heat treatment device for an air cylinder groove, which comprises a device main body and a control system; the device main body is provided with a main heating zone andan assistant heating zone; the main heating zone covers a to-be-repaired position of the air cylinder groove, and the assistant heating zone is located in at least one side of the main heating zone;heating components are arranged in the main heating zone and the assistant heating zone; the control system is connected with the heating component for controlling the work of the heating component and the heating temperature. Through the main heating zone, the to-be-repaired zone is heated; the main heating zone is performed with assistant heating and heat insulation through the assistant heatingzone, so as to realize heat treatment of every part of the groove; the heat treatment temperature and time are effectively controlled, thus no partial overheat is guaranteed; the main heating zone and the assistant heating zone can be set and switched according to the repair zone; the heat treatment effect is good.

Description

technical field [0001] The invention relates to a heat treatment device, in particular to an on-site heat treatment device for cylinder grooves. Background technique [0002] The corner area of ​​the cylinder groove is a stress concentration area, which is prone to cracks, thus affecting its normal use. In the prior art, when a crack occurs in the cylinder groove, it will be repaired, usually by welding, and then heat treated after welding. The online heat treatment of the cylinder groove adopts flame baking, but the temperature and time of this heat treatment method are difficult to control, so the heat treatment effect is not very ideal. Contents of the invention [0003] The object of the present invention is to provide a device for on-site heat treatment of cylinder grooves. [0004] In order to achieve the above object, the technical scheme adopted in the present invention is: [0005] A device for on-site heat treatment of cylinder grooves, comprising: [0006] D...
