Welding-with-trailing impact rolling welded seam shaping device for welded joint

Abstract

The invention discloses a welding-with-trailing impact rolling welded seam shaping device for a welded joint. The welding-with-trailing impact rolling welded seam shaping device comprises a vibrationtelescopic device, and further comprises a main rolling wheel and an auxiliary rolling wheel which are arranged at the bottom of the vibration telescopic device and located on the same horizontal plane; the main rolling wheel comprises a cylinder body and bowl-shaped bosses symmetrically arranged at the two ends of the cylinder body, a plurality of punching protruding patterns are evenly arrangedon the outer surface of the cylinder body at intervals along the circumference, and a first pin through hole is formed in the center of the cylinder body and the center of the bowl-shaped bosses; andin the horizontal direction of the cylinder body along the bowl-shaped bosses, the outer diameters of the bowl-shaped bosses are gradually decreased, and the outer diameters of the edges of the ends,away from the cylinder body, of the bowl-shaped bosses are slightly greater than the outer diameter of the cylinder body. The high-temperature welded seam after welding are treated by the structure ofthe welding-with-trailing impact rolling welded seam shaping device, the organization structure of the welded seam can be improved, the welding quality of the welded joint and the welded seam is improved, and thus the service life of a weldment is prolonged. The welding-with-trailing impact rolling welded seam shaping device is easy to operate and simple in structure, a control system can be additionally arranged to achieve automation, and manpower is saved.

Description

technical field [0001] The present application relates to a welding seam shaping device for impact rolling with welding of welded joints. Background technique [0002] Welding is a basic process of engineering construction, and it is also a very widely used engineering technology. However, welded joints and welds are often accompanied by some defects, and the organizational structure of some welded joints and welds is not satisfactory. For example, for metals with poor heat dissipation, the weld pool crystallizes slowly, and generally may form a coarse grain structure, and may also form segregation, thermal cracks, etc. Therefore, this patented design is proposed, which can be designed into different powers according to different needs, and applied to different welding occasions to carry out impact rolling and shaping of the weld to improve the quality of the weld. [0003] There are not many patented designs for impact rolling and shaping of welded joints. Fang Hongyuan, W...

AI Technical Summary

Problems solved by technology

The above-mentioned patent has many advantages, and also overcomes many deficiencies of traditional techniques. However, under the same power, the equipment of the air hammer is relatively large and takes up a large space. When the hammering speed and frequency are adjusted, there is a sudden change, which is not good for the operation of the equipment.

The traditional welding seam improvement and shaping technology is mostly simple, labor-intensive, and slightly inefficient
