Technical Field
[0001] The utility model relates to a welding windproof device for a welding gun of a carbon dioxide gas shielded welding, belonging to the technical field of carbon dioxide shielded welding equipment. Background Art
[0002] Carbon dioxide gas shielded welding is an important part of the welding process. The shielding gas used in carbon dioxide gas shielded welding is carbon dioxide, which is mainly used for manual welding. Due to the low price of the carbon dioxide shielding gas used, the weld is well formed when short-circuit transition is adopted, and the use of welding wire containing deoxidizer can obtain a quality welded joint without internal defects. This welding method has become one of the most important welding methods for ferrous metal materials. One of the problems with carbon dioxide gas shielded welding at present is that the welding gun is easily affected by the flowing air when welding outdoors. Especially when the wind is relatively strong, the carbon dioxide gas is blown by the wind, resulting in the chaos of the carbon dioxide gas at the welding point, which is easy to weld the pores and also easy to cause the welding to be loose, which seriously affects the welding quality. However, many equipment cannot be moved indoors for welding operations, so how to prevent wind is a problem that must be solved when using carbon dioxide gas for welding outdoors. At present, it is usually used to shield the welding site with a baffle, but due to the location and shape of the equipment being welded, it is sometimes difficult to shield, which affects the welding operation and welding quality. It is very necessary to solve it to maintain the quality of outdoor carbon dioxide gas welding. Utility Model Content

[0021] Figure 2 , 3 , 4 shows that the windproof device includes a windproof part and a blowing part.
[0022] The windproof part includes a fixing ring 5, a fixing bolt 7, a connecting seat 8, a rotating shaft 9, a windproof plate 10, an elastic connecting piece 11, a collar 12, and a thread 13. The function of the windproof part is to prevent the air outside the welding gun 3 from interfering with the carbon dioxide gas during welding, so as to ensure the normal progress of welding.
[0023] The blowing part includes a small air compressor 1, an air outlet annular sleeve 14, an air inlet pipe 15, an air blowing pipe 16, and an air blowing nozzle 17.
