Shot blasting treatment method for solving shot blasting deformation of blades

Abstract

The invention discloses a shot blasting treatment method for solving shot blasting deformation of blades. The shot blasting treatment method comprises the following steps: a, determining process parameters of shot blasting according to technical requirements of shot blasting treatment; b, selecting at least three blades with stable processing states to carry out shot blasting treatment; c, detecting shot blasting deformation amount of the blades subjected to the shot blasting treatment; d, selecting blades, with stable processing states, to be subjected to shot blasting treatment, and pre-deforming the blades to be subjected to shot blasting treatment in a reverse direction according to the detected shot blasting deformation amount; e, adopting the same shot blasting process parameters to carry out shot blasting treatment on the pre-deformed blades; and f, detecting the blades subjected to shot blasting treatment, and determining whether the dimensions of the blades meet the requirements or not. According to the shot blasting treatment method, pre-deformation is carried out on the blades before blasting treatment is carried out in the reverse direction according to the shot blasting deformation amount, and then, shot blasting treatment is carried out on the blades, so that the shot blasting deformation balances out the pre-deformation, and the dimensions of the blades subjected to the shot blasting treatment are guaranteed to be within a tolerance range, and therefore, the shot blasting deformation problem of the blades is effectively solved.

Description

technical field [0001] The invention relates to the field of shot peening treatment of blades, in particular to a shot peening treatment method for solving the shot peening deformation of blades. Background technique [0002] The blade is a typical thin-walled structural part. During the production process, it needs to go through the shot peening process, and then introduce residual stress inside the blade to improve the fatigue strength and fatigue life of the blade and prolong the service life of the blade. However, the blades generally have the characteristics of thin wall, torsion, wide chord and poor rigidity. This makes the blade very prone to blade deformation during the shot peening process; if the shot peening deformation is not handled properly, once the blade deformation exceeds the specified tolerance range, it may cause the size to be out of tolerance and face the risk of scrapping. Therefore, urgently need to solve. Contents of the invention [0003] The ob...
