The invention discloses an acoustic-liquid-solid coupling two-dimensional ultrasonic deep rolling processing device, which at least includes an acoustic component, a hydraulic component and a tool component; Balls that can impact the surface of the workpiece; the acoustic component includes a horn, an ultrasonic transducer, and an ultrasonic generator connected to the ultrasonic transducer through a wire. The ultrasonic transducer is installed on the horn; the hydraulic component includes a The liquid supply pipeline on the base communicates with the groove of the base. The acoustic-liquid-solid coupling two-dimensional ultrasonic deep rolling processing device of the present invention integrates the advantages of deep rolling processing and two-dimensional ultrasonic processing, and utilizes the coupling effect of two-dimensional ultrasonic field and flow field to generate ultrasonic impact, ultrasonic cavitation and jet polishing, through The balls act on the workpiece to achieve high-quality and efficient surface strengthening of low-rigidity metal workpieces and increase the service life of the balls.
Description
technical field [0001] The invention relates to the technical field of surface strengthening of metal parts, in particular to an acoustic-liquid-solid coupling two-dimensional ultrasonic deep rolling processing device. Background technique [0002] Metal parts are widely used in various mechanical equipment. Since metal parts are often damaged due to surface wear, corrosion and fatigue, it is usually necessary to use surface strengthening techniques such as rolling and shot peening to improve the processing quality and surface mechanical properties of metal parts and improve wear resistance. Corrosion and fatigue resistance to extend the life of metal parts. [0003] Ultrasonic deep rolling is formed by the combination of rolling and ultrasonic machining. It is a kind of surface strengthening treatment technology. It was developed by Bozdana et al. in 2005 on the basis of deep rolling. They use ultra-high pressure fluid to make the ball and the workpiece tightly Contact, t...
