Description

Technical Field

[0001] The utility model relates to the technical field of two-way welding machines, in particular to a protective mechanism for a two-way welding machine. Background Art

[0002] Gas shielded welding is an arc welding that uses gas as the arc medium and protects the arc and welding area. It is called gas shielded arc welding, or gas shielded welding for short. Gas shielded welding machines are widely used in various fields, and are particularly outstanding in some parts processing fields. Therefore, people have developed a variety of gas shielded welding machines, which are divided into many types according to different shielding gases. Among them, carbon dioxide shielded welding machines are generally popular because of their cheap gas, high safety, and no odor. They are particularly widely used.

[0003] The reference patent (publication number: CN211248738U; publication date: 2020-08-14) discloses a two-protection welding machine protective device, including a support frame, a gas welding machine body is fixedly installed on the upper surface of the support frame bottom plate, a wire feeding mechanism is fixedly installed on one side of the inner cavity of the support frame, a smoke purifier is fixedly installed on one side of the outer surface of the support frame, and the upper end of the smoke purifier is fixedly connected to two conduits, and the upper ends of the two conduits are fixedly connected to a smoke absorption port. The two-protection welding machine protective device is fixedly welded on one side of the upper surface of the support frame. When the gas welding gun is used, due to the high temperature generated during the welding process, if the gas welding gun is placed randomly at this time, the gas welding gun is easily burned or burns objects or workers that come into contact with it. At this time, the gas welding gun can be inserted into the placement ring. The gas welding gun in the placement ring is in a suspended state, which is convenient for it to cool down by itself, avoiding burns due to negligence of the staff.

[0004] During the use of existing two-guard welding machines, welding operations are often accompanied by dangerous factors such as high temperature and spark flying, which pose a threat to the safety of operators. At the same time, traditional two-guard welding machines require operators to directly hold the welding gun for welding, which is easy to come into contact with the high-temperature welding area, increasing the risk of burns and electric shocks. In addition, manual support of the welding gun makes it difficult to ensure the stability and accuracy of the object during the welding process. Especially when welding large or complex structures, movement or shaking is prone to occur, affecting the welding quality and easily causing danger. For this reason, the utility model provides a two-guard welding machine protection mechanism. Utility Model Content
