Description
Technical Field
The invention belongs to the technical field of material performance research, and particularly relates to a method and a device for manufacturing a low-stress high-energy sound beam of a thermal-state disc component.
Background
The disc type component can generate stress on the surface thereof in the hot state manufacturing process, and can generate deformation and even cracking due to the release of residual stress on the surface thereof in the later use process, thereby influencing the normal use of the disc type component. Stress control for disc like members during manufacturing is very important.
Common residual stress reduction methods include a natural aging method, a vibration aging method, a heat treatment method (heat treatment) and the like, wherein the natural aging method is simple, but takes too long time and has low efficiency; the vibration aging method enables the component to resonate through a vibration exciter so as to relax and relieve the residual stress in the component, but the vibration aging method has higher requirements on the technical level of operators and complicated process parameter setting, and if the vibration excitation point and the parameter are improperly set, the component can be subjected to periodic fatigue or even damage due to an abnormal resonance mode, so that the method is not suitable for stress regulation and control of manufacturing of disc components; the thermal aging method, i.e., the annealing heat treatment method, often fails to achieve the effect of stress reduction and even increases stress deformation if the process parameters are improperly selected in the processes of temperature rise, heat preservation and temperature reduction.
In addition, ultrasonic impact treatment, electric shock aging method, magnetic pulse method, and the like are available. However, according to the research of r.sougata doctor and w.john researcher of ATLSS engineering research center of lihay university, pa, usa on ultrasonic impact, it is found that the high-frequency impact can not control the internal residual stress state and can cause fine crack damage to the component surface. According to the research of the electric shock aging method by the teaching of heaven of university at Zhejiang, the method is found to be suitable for all conductive and insulating materials, but can damage the metal surface and is not easy to regulate. Although the Chua Shipeng research institute of Qinghua university improves on the magnetic pulse method, the method is not suitable for materials that are not magnetically conductive.
Furthermore, patent publication No. CN110860953A discloses a method for processing a high-temperature alloy disk part by vibration finishing, which is limited to the alloy disk part, although the object is the high-temperature disk part, and the processing method is to improve the stress state of the workpiece surface by etching and grinding the surface of the part by an excitation source to drive an abrasive, which cannot be applied to a non-metal disk member, and the outer surface of the member is changed while performing stress control.
