Problems solved by technology

[0004] The existing welding fixtures have a poor fixing effect on metal pipes. Usually, circular hoops are used for fixing directly. In the process of welding, vibrations sometimes occur, and the vibration is caused by the extrusion of the pipes on the circular hoops. Because the fixing device itself has no components that can buffer the extrusion force, the circular hoop will be offset if it is squeezed for a long time, and the offset of the circular hoop during the process of fixing the round tube will easily cause the tube to deflect. Shift, thus affecting the welding quality

Abstract

The invention provides a fixing device for metal welding, and relates to the technical field of fixing devices for welding. The fixing device for metal welding comprises a workbench, wherein limitinggrooves are formed in the two ends of the top of the workbench; an impurity storage groove is formed in the position, between the two limiting grooves, of the top of the workbench; rust removal assemblies are fixedly installed at the positions, located at one ends of the two limiting grooves, of the top of the workbench; and fastening devices are fixedly installed at the positions, located at theother ends of the two limiting grooves, of the top of the workbench. According to the fixing device for metal welding provided by the invention, through double position adjustment, fixing is more accurate; meanwhile, buffer springs are arranged, so that the resilience force of the buffer springs effectively counteracts vibration generated in the welding process, and the occurrence of the phenomenon that a traditional circular hoop deviates due to long-term extrusion, and consequently the welding quality is affected by pipe deviation is avoided; and meanwhile, anti-skid strips are arranged on the inner walls of clamping hoops, so that the situation that the pipeline slips during welding can be further prevented, and the welding precision is improved.

Description

technical field [0001] The invention relates to the technical field of fixing devices for welding, in particular to a fixing device for metal welding. Background technique [0002] With the development of society, the forging and application of metal pipes are becoming more and more extensive in my country. Some pipes are devices used to transport gas, liquid or fluid with solid particles. Due to their unique characteristics, the pipes are widely used in many industries. Industry, many fields, pipelines are widely used, mainly used in water supply, drainage, heat supply, gas supply, long-distance transportation of oil and natural gas, agricultural irrigation, water conservancy projects and various industrial devices. [0003] As a type of pipeline, metal pipes are widely used in the construction process of chemical buildings. In the prefabrication process of metal pipes, metal pipes often need to be welded. According to the requirements of the welding process, butt welding an...
