Embodiment Construction

[0022] The method for plastic deformation correction of mechanical parts according to the embodiment of the present invention includes:

[0023] First check the direction of the plastic deformation of the part, and check the size of the plastic deformation;

[0024] Then determine the stress factors of plastic deformation;

[0025] Then perform local high-frequency heating on the deformed part of the part until the crystal structure changes locally, and then apply external stress to the deformed part;

[0026] The external stress is determined according to stress factors;

[0027] The shape stress adopts a curved structure and adopts multi-point force restoration. For the part with the largest deformation position, the applied external stress is also the largest, and then the stress is gradually reduced according to the magnitude of the deformation. When the external deformation is not obvious, only surround the deformed part Apply external stress to half of the deformed part at the ce...

Abstract

The invention discloses a method for correcting plastic deformation of a mechanical part. The method comprises the steps that the direction of part plastic deformation is detected, and the size of plastic deformation is checked; stress factors of plastic deformation are determined; local high-frequency heating is carried out on a deformed part of the part until part of the part is changed in the crystal structure, and external stress is exerted on the deformed part; the external stress is determined according to the stress factors. According to the method for correcting plastic deformation of the mechanical part, designing is carried out on plastic deformation of the part, during implementation, restoring needs to be carried out for the size of plastic deformation, the deformed area and the stress factors caused by deformation, high-frequency heating is adopted during restoring, and for the deformed part, the deformed part can be gradually restored into the initial shape through the external force.

Description

Technical field [0001] The invention relates to a method for correcting plastic deformation of mechanical parts, belonging to a method for correcting plastic deformation generated by mechanical parts. Background technique [0002] The deformation of the parts of mining machinery parts in the use process is inevitable. Therefore, during the overhaul of mining machinery, it is not only necessary to check the wear of the mating surface, and the mutual position accuracy must also be carefully checked and repaired. Especially for the first major repair of the deformation of the mining machinery, attention should be paid to inspection and repair, because the deformation of the parts under the action of internal stress is usually completed within 12-20 months. [0003] Under long-term use conditions, mechanical parts will produce certain plastic deformations. These plastic deformations generally directly lead to the scrapping of the entire mechanical parts. Therefore, the damage caused by...
