The technical scheme includes that the simple device for screening parts containing residual stress comprises a workbench, a vibration machine and a base. The vibration machine is connected to the lower surface of the workbench, the workbench and the base are connected through a plurality of press springs, a layer of rubber plate is arranged on the upper surface of the workbench, and a plurality of elastic bands are arranged on the rubber plate. By means of the simple device for screening parts containing residual stress, problems of recognition and screening of parts containing residual stress are solved, the screening efficiency is high, the structure is simple, the cost is low, and the operation is facilitated.
Description
technical field [0001] The invention belongs to the technical field of precision machinery manufacturing, and in particular relates to a simple device for screening parts containing residual stress and an application method thereof. Background technique [0002] When the metal material is heat treated, the metallographic transformation is accompanied by the decrease of the temperature, but this transformation is often not complete. At room temperature, some metallurgical structures (such as austenite) at high temperature will remain, and it will suddenly change with the passage of time or external force. The metallographic structure (such as martensite) at room temperature will cause deformation of the part due to the different density of the two metallographic structures; during the processing of the part, the deformation of the part is mostly corrected by the "cold correction" method, and the material simultaneously exists Residual stress is generated by plastic and elasti...
