Problems solved by technology
In the process, the mixed liquid (alloy powder group) of Cu-Al-Zn three metal powders is brushed on the welded lap joints with a brush. This treatment method is inefficient, and the quality of manual brushing is difficult to guarantee. , it is easy to cause spot welding quality problems due to uneven thickness; and, for spot welding of different metals (such as Al-Cu, Mg-Fe, Mg-Mg), the coating thickness of the alloy powder group is required to be different, so a kind of Coating device capable of adjusting and controlling the thickness of alloy powder clusters

The invention discloses an adjustable type alloy powder ball scrape coating system comprising a base. A lifting compressing seat is arranged on the upper side of the base. The lifting compressing seat is provided with scrape coating grooves. Lifting scrape blade assemblies are arranged on the lifting compressing seat. The lifting scrape blade assemblies extend into the scrape coating grooves. Distance adjusting devices are arranged between the lifting compressing seat and the lifting scrape blade assemblies. The adjustable type alloy powder ball scrape coating system has the remarkable effects that scrape coating of alloy powder balls can be evenly, stably and efficiently conducted in a multi-point manner, the scrape coating thickness can be accurately controlled, operation is easy, the scrape coating quality of the alloy powder balls is high, and the adjustable type alloy powder ball scrape coating system is suitable for scrape coating of different thicknesses and beneficial for the improvement of the spot welding quality of brittle metal.
Description
technical field [0001] The invention relates to a spot welding auxiliary device, in particular to an adjustable alloy powder ball scraping system. Background technique [0002] For some brittle metals, it is difficult to form a solid solution during spot welding, so the welding quality is not good. In an earlier study, the researchers found that for spot welding between homogeneous metal Mg, by using Cu-Al-Zn three metal powders, a microalloyed zone can be formed at the welded joint of metal Mg, thereby harvesting the nugget Regular symmetry, excellent effect of enlarged nugget size; the shear resistance and corrosion resistance of welded joints are also significantly increased, and the quality of spot welding is improved. In the process, the mixed liquid (alloy powder group) of Cu-Al-Zn three metal powders is brushed on the welded lap joints with a brush. This treatment method is inefficient, and the quality of manual brushing is difficult to guarantee. , it is easy to ca...
