Description
Technical Field
The invention relates to a magnetic automatic ultrasonic impact machine for eliminating welding residual stress, belonging to the field of welding.
Background
After the metal material is welded by adopting various welding methods, the welding seam is easy to generate larger welding residual stress, especially larger tensile stress on the surface of the welding seam, if the residual stress is eliminated or reduced by adopting a technical means, surface cracks and even fracture are easy to generate when the welding seam is in service, especially high-strength steel, high-carbon steel or a large thick plate, and cracks or fractures caused by the residual stress on the surface of the welding seam are easy to generate on the seam of a complex welding joint. The traditional method for eliminating the welding residual stress is to adopt stress relief annealing under the allowable condition, so that the residual stress of a welding seam can be eliminated to a great extent or completely, but in the actual production, not all welding structures can adopt the stress relief annealing method.
The ultrasonic welding stress relief equipment method is a relatively popular postweld treatment method abroad, and the basic principle of the ultrasonic welding stress relief equipment is that a high-power ultrasonic wave is utilized to push an impact tool to impact the surface of a metal object at a frequency of more than twenty thousand times per second, and the metal surface layer generates relatively large compression plastic deformation due to the high frequency, high efficiency and large energy under focusing of the ultrasonic wave; meanwhile, the original stress field is changed by ultrasonic welding stress relief equipment waves, and the compressive stress with a certain numerical value is generated; and the method can strengthen the impacted part, strengthen the surface locally and eliminate the residual stress. The method is firstly developed rapidly in the United states in the sixties of the twentieth century in the Ukrainian of the former Soviet Union, is acknowledged as the most effective method for improving the fatigue performance of a welded structure, and is rapidly popularized and applied in developed countries, an ultrasonic welding stress relief device is used as post-welding treatment equipment, and can simultaneously improve a plurality of factors influencing the quality of a welding seam, such as stress, defects, geometrical shape of a welding toe, surface strengthening and the like, so that the method has the effect of improving the fatigue performance of the welding joint with half effort, can improve the fatigue strength of the treated welding joint by 50-120 percent, and prolong the fatigue life by 5-100 times. After the ultrasonic welding stress relief device is adopted for treatment, the traditional grinding and deslagging procedures are omitted, the labor time is saved by 20%, the labor intensity is reduced, and the production efficiency is improved. Meanwhile, the method is also widely applied to the following three aspects: (1) strengthening treatment is carried out on the surface of the metal part so as to improve the surface quality and the fatigue life of the part; (2) the stress field is adjusted, the welding deformation is reduced, and the dimensional stability of the workpiece is ensured; (3) and (4) carrying out treatment for eliminating welding stress on the local welding repair part of the mechanical part. The method is widely used in foreign mechanical manufacturing engineering, in particular to welding structure engineering with higher requirement on fatigue performance and requirement on residual stress elimination.
Ultrasonic impact eliminates welding residual stress equipment generally comprises two parts, power and impact rifle, and both pass through the power cord and connect, and the manual hand is strikeed the rifle during use, and to the seam impact, because it is bigger to strike the rifle quality, and there is vibrations when strikeing, consumes workman's physical power very much for long-time during operation. At present, a large number of high-strength steel large thick plate welding joints exist in the production of large steel structures, such as peripheral anti-collision containment vessels in nuclear power engineering, large pressure vessels and the like, a large number of long straight or regular welding seams exist in the steel structures, if the welding seams are eliminated by adopting a traditional ultrasonic impact welding residual stress eliminating machine to eliminate welding stress, the welding seams are a time-consuming and labor-consuming project and need a large amount of manpower for processing, mechanical and automatic welding is easily realized for a large number of straight or large-bending-radius welding seams, and meanwhile, the mechanical and automatic ultrasonic impact welding residual stress elimination can also be realized.
