Thermal vibration and shot peening integrated composite process stress adjusting and control device

Abstract

The invention relates to a thermal vibration and shot peening integrated composite process stress adjusting and control device. Through the integrated design of a temperature part, a vibration part and a shot peening part, composite remaining stress regulation involving both part surface stress enhancing and internal stress homogenization is carried out. The device comprises the temperature part,the vibration part, the shot peening part, the control part and other parts. The temperature part and the vibration part act independently or in a coupled mode to homogenize part remaining stress. Theshot peening part achieves reinforcement of the part surface layer stress. The control part implements integrated control of process parameters. Other parts are used for device connection and processassistance. Compared with the prior art, the thermal vibration and shot peening integrated composite process stress adjusting and control device has the remarkable advantages that (1) the thermal vibration and shot peening integrated composite process stress adjusting and control device realizes stress regulation and control device integration; (2) through the joint effort of the vibration part,the maximum dynamic stress acts on a part, and the remaining stress homogenization effect is improved; and (3) an integrated integration device effectively improves the stress adjusting and control efficiency.

Description

technical field [0001] The invention relates to a thermal vibration-shot peening integrated process stress control device, which belongs to the field of mechanical manufacturing process. Background technique [0002] With the development of a new generation of aerospace products, the demand for weight reduction of various structural parts is increasing, and the performance requirements for parts are getting higher and higher. Some of its key parts are in service under high temperature and vibration conditions, so necessary stress regulation is required during the part manufacturing process. In the manufacturing process of aerospace parts, a large amount of material needs to be removed. Due to the coupling of initial residual stress and cutting stress inside the part, the parts are prone to deformation after machining. The accumulation of a large amount of residual stress in the material will lead to the expansion of cracks on the surface of the part. The thermal aging metho...
