Tool and method for eliminating, reducing and homogenizing residual stress of components in machine tool machining

Abstract

The invention provides a device and method for eliminating, reducing and homogenizing the residual stress in the milling, boring, drilling, planning and other machining processes in which machined components are fixed and kept unmoved. According to the device and method, a plurality of high-energy sound wave exciters on a working table are tightly coupled with the components coated with coupling media, high-energy sound waves are emitted into the components, and the residual stress inside the machined components is eliminated, reduced and homogenized by utilizing the elastic wave energy whichis generated in the components by the high-energy sound waves. Thus, the purpose that the residual stress is eliminated and homogenized and meanwhile machining is carried out is achieved, the stress-elimination-free machining control is achieved, and it is ensured that the deformation amount in the machining process of the mechanical components and the deformation amount after the machining are the minimum.

Description

technical field [0001] The invention relates to the technical field of machine tool processing, in particular to a residual stress reduction and homogenization device and method suitable for processing components such as milling, boring, drilling and planing which are fixed during processing. Background technique [0002] When using a machine tool to process metal materials of large size or thickness, in order to ensure the overall integrity of the mechanical components, it is often necessary to remove the components with a large amount of milling, and the deformation caused by improper clamping of the components can basically be eliminated by manual measures. However, due to the uneven internal residual stress, the machining deformation of mechanical components cannot be effectively controlled. The greater the thickness of the raw material, the poorer the uniformity of the internal residual stress, and the more serious the imbalance of the internal residual stress during pr...
