Description

Technical Field

[0001] The utility model relates to the technical field of machinery, in particular to an automatic submerged arc welding fixing component applied to arc-shaped steel plates. Background Art

[0002] Submerged arc welding machine is a welding machine that uses electric arc burning under the flux layer for welding. Its inherent advantages such as stable welding quality, high welding productivity, no arc light and little smoke make it the main welding machine in the production of pressure vessels, pipe segment manufacturing, box beam and column steel structures, etc. In recent years, although many new types of efficient and high-quality welding machines have appeared one after another, the application field of submerged arc welding machine has not been affected in any way. From the perspective of the share of the weight of the deposited metal of various fusion welding machines, submerged arc welding machines account for about 10%, and there has been little change over the years. Submerged arc welding machine consists of welding power supply, welding head and auxiliary equipment. Its power supply can use AC, DC or AC and DC. Submerged arc welding equipment consists of three parts: power supply, control cable and trolley. Each part is very important. Only when they are well coordinated can the advantages of submerged arc welding be fully utilized.

[0003] However, the submerged arc welding fixing components currently on the market are not only complex in structure, but also single in function. The conventional submerged arc welding fixing components are not provided with a sliding rod and a sliding sleeve. When the submerged arc welding machine is working on the curved steel plate, it is not convenient to control the direction of the submerged arc welding machine, which increases the working time and reduces the working efficiency. The conventional submerged arc welding fixing components are not provided with a limiting hole. When the submerged arc welding machine stops on the curved steel plate, if the curved steel plate has a slope, the submerged arc welding machine is easy to slide or fall over, which is easy to damage the submerged arc welding machine. For example, the submerged arc welding machine disclosed in Publication No. CN207272394 U is an automatic submerged arc welding fixing component applied to arc-shaped steel plates. The submerged arc welding machine of the automatic submerged arc welding fixing component applied to arc-shaped steel plates slides on the surface of the steel plate and welds when working. After welding, the driving component is turned off to stop the submerged arc welding machine. The submerged arc welding machine is turned on and off manually. When the welding position is finished, the submerged arc welding machine is turned off. However, during welding, the welding position will be blocked by a large amount of flux to block the welding path. The submerged arc welding machine may weld too much or too little on the surface of the steel plate, and the welding accuracy is poor.

[0004] Therefore, it is necessary to provide an automatic submerged arc welding fixing assembly for arc-shaped steel plates to solve the above-mentioned technical problems. Utility Model Content
