Problems solved by technology
[0003] Some existing practical back protectors for non-ferrous metal welding are mostly fixed in structure. When used for different sizes of welds, it is often necessary to prepare different sizes of protectors, resulting in the problem of high cost of use. At the same time, its gas transmission Most of the pores of the device directly face the welding position, and the impact of inert gas is prone to the problem of pores in the welding position, which affects the quality of welding

The invention discloses a practical back protection device for non-ferrous metal welding. The practical back protection device comprises a fixing frame, movable grooves are formed in the two sides ofthe outer surface of the fixing frame, movable frames are arranged in the positions, corresponding to the two movable grooves, in the fixing frame, a plurality of movable inner grooves are evenly distributed in the positions, close to the bottom, in the two movable frames, moving blocks are arranged in the multiple movable inner grooves correspondingly, and reset springs are connected between onesides of the inner walls of the multiple movable inner grooves and one sides of the outer surfaces of the multiple moving blocks correspondingly. According to the practical back protection device, thewhole structure is stable in connection and convenient to use, a cavity can be formed through cooperation of the fixing frame and the movable frame, a stable atmosphere environment can be stably provided for inert gas below the welding position in cooperation with a gas conveying structure, therefore the welding quality is guaranteed, the structure of the movable frame can be adjusted, the structure can adapt to weld joints of different sizes, the universality is higher, and the adaptability is wider.
Description
technical field [0001] The invention relates to the technical field of material processing, in particular to a practical back protection device for non-ferrous metal welding. Background technique [0002] For the welding of non-ferrous metals, in order to prevent them from reacting with oxygen, hydrogen, nitrogen and other molecules in the air due to high temperature, inert gas is usually used to protect the back, so the back protection device for non-ferrous metal welding has a Certain needs. [0003] Some existing practical back protectors for non-ferrous metal welding are mostly fixed in structure. When used for different sizes of welds, it is often necessary to prepare different sizes of protectors, resulting in the problem of high cost of use. At the same time, its gas transmission Most of the pores of the device directly face the welding position, and the impact of inert gas is prone to the problem of pores in the welding position, which affects the quality of welding...
