Submerged automatic arc welding equipment and welding process based on steel structural part production

Abstract

The invention belongs to the technical field of steel structural part welding, particularly relates to submerged automatic arc welding equipment and a welding process based on steel structural part production, and provides the following scheme that the submerged automatic arc welding equipment comprises a welding table and a protective cover, a connecting frame is fixedly connected to the outer wall of the protective cover, and a slag treatment assembly is arranged on the connecting frame. According to the automatic submerged arc welding device, the movable feeding and discharging assembly is arranged, when submerged arc automatic welding operation of steel structural parts is conducted, the steel structural parts are placed on all the movable rollers, fourth air cylinders at the two ends are adjusted to drive clamping plates to move, and therefore the steel structural parts are clamped; and a fourth air cylinder at one end drives a clamping plate to push the steel structural part, and a fourth air cylinder at the other end drives the clamping plate to limit the steel structural part, so that the steel structural part moves on the moving rollers, manual position adjustment is not needed in the whole welding process, safety accidents are avoided, and meanwhile, the labor input is reduced.

Description

technical field [0001] The invention relates to the technical field of welding of steel structural parts, in particular to a submerged arc automatic welding welding equipment and a welding process based on the production of steel structural parts. Background technique [0002] Submerged arc automatic welding has the advantages of high productivity, high degree of mechanization, good and stable welding quality. Submerged arc automatic welding has been widely used in metal structures, bridges, pressure vessels, petrochemicals, nuclear vessels, oil and gas pipelines, shipbuilding and other fields. The workload of submerged arc welding is very large, and the amount of steel, welding wire and flux consumed is also large. Therefore, although the submerged arc welding technology is relatively mature and not the latest technology, there are often quality problems in production, and the welding equipment will inevitably fail. [0003] In the production process of the existing steel...

Problems solved by technology

[0004] The object of the present invention is to provide submerged arc automatic welding welding equipment and welding process based on the production of steel structural parts, so as to solve the problem that existing steel structural parts need to be welded by submerged arc automatic welding equipment in the production process. Some submerged arc automatic welding devices will produce part of the slag during the welding operation of the steel structure. This part of the slag will solidify above the molten pool as the molten pool solidifies, and the protective layer formed by the welding slag will It plays the role of anti-oxidation. However, this part of the slag is arranged in a disorderly manner above the molten pool. After solidification, only a local area plays the role of anti-oxidation. The poor degree of precision affects the overall aesthetics of the steel structure, leading to the problem that the use value of the submerged arc automatic welding equipment is reduced. The submerged arc automatic welding equipment produced based on the steel structure includes a welding table and a protective cover. The protection The outer wall of the cover is fixedly connected with a connecting frame, and a slag processing assembly is provided on the connecting frame, and the slag processing assembly includes a plurality of pressing column integrations, and each pressing column integration includes a plurality of pressing columns, located in each Each adjacent two pressing columns on the pressing column integrated body are connected by a hinge, and multiple pressing column integrated bodies are arranged in parallel, and each pressing column is equipped with an electric heating wire inside, and the connecting frame The outer wall of the bottom is fixedly connected with the No. 2 hydraulic cylinder, and the output end of the No. 2 hydraulic cylinder is fixedly connected with the lower pressure plate, and the outer wall of one side of the lower pressure plate is fixedly connected with the No. 3 hydraulic cylinder, and the output end of the No. 3 hydraulic cylinder is fixedly connected with the adjustment frame. Both ends of the adjustment frame are fixedly connected with end plates, and the outer walls of the opposite sides of the two end plates are fixedly connected with No. No. 4 hydraulic cylinders are fixedly connected to the outer walls of the bottom of the frame, the output ends of the two No. 4 hydraulic cylinders are fixedly connected to fitting rods, and the pressing columns at both ends are connected to the outer walls of the fitting rods through hinges;
