Problems solved by technology
However, there are some problems in the above two methods. The production cost of the circulating water cooling fixture is high, the flexibility is poor, and the cooling of the circulating water requires special equipment, and when using low-temperature substances such as liquid nitrogen and dry ice for cooling, the volatilized gas will cause environmental damage. affect and even threaten human health, so it is rarely used in welding production

The invention discloses a welding auxiliary cooling device, and relates to the technical field of welding. The device comprises flexible heat exchangers which are ranged on the two sides of a welding way and move synchronous with a welding gun and fixed heat exchangers which are arranged below a welding part and on the two sides of the welding way, the front ends of the flexible heat exchangers are connected with a traction component, the bottoms of the flexible heat exchangers are of flexible heat conduction structures, refrigerants connected with a refrigerating device are led into the flexible heat exchangers and the fixed heat exchangers, and the flow direction of the refrigerants in the flexible heat exchangers and the fixed heat exchangers is opposite to the welding direction. The traction component is used for driving the flexible heat exchangers on the two sides of the welding way to move along with moving of the welding gun, meanwhile, the refrigerants circularly flowing in the flexible heat exchangers and the fixed heat exchangers which are arranged on the upper side and the lower side of the welding way are used for absorbing heat generated in the welding process, and the heat exchange aim is achieved. The device is simple in structure, convenient to operate and capable of reducing the heat affecting area of welding, the quality of a welding joint is improved, and the service life of the welding joint is prolonged.
Description
technical field [0001] The invention relates to the field of welding technology, in particular to a welding auxiliary cooling device. Background technique [0002] At present, welding, as a basic manufacturing connection process, is widely used in many industrial fields such as machinery manufacturing, petrochemical industry, rail vehicles, aerospace, shipbuilding, household instruments and military weapons. In most welding processes, the base metal and the welding material to be filled are melted into liquid metal and mixed by heating (such as arc heat, chemical heat, resistance heat, etc.), and the liquid metal solidifies during the subsequent cooling process to form a weld. While heating to form a weld to realize the connection, this local heating will also form an uneven temperature field, which will lead to the ubiquity of stress and deformation of the welded joint. The conduction of heat to the base metal area will also lead to changes in material properties and struc...
