Description

Technical Field

[0001] The utility model relates to a cooling device, in particular to a cooling device for a welding conveying line, belonging to the technical field of cooling devices. Background Art

[0002] Metal welding refers to a forming method that uses heating or pressurization, or both, to create an interatomic bond between two separated metals and connect them into one. According to the degree of heating and process characteristics during the welding process, welding methods can be divided into fusion welding, pressure welding and brazing. Fusion welding is the most common. The specific operation is: the welding part of the workpiece is locally heated to a molten state to form a molten pool, which is cooled and crystallized to form a weld. The welded workpieces are combined into an inseparable whole.

[0003] However, in some special welding processes, high temperatures are not required or rapid cooling is required after welding in order for the welded parts to be firmly welded. In this case, a cooling device is needed to cool the welded parts in time. When air cooling is used in welding production lines, most of them are one-way air cooling. When the workpiece size is large and the cooling range of the air duct is fixed, the cooling effect of the workpiece is different, which affects the molding quality of the workpiece. In addition, the temperature in the welding work area is high after working for a long time, and the working environment needs to be cooled. Utility Model Content
