Description

Technical Field

[0001] The utility model relates to the technical field related to welding processing of sheet metal bending products, in particular to a welding tool for sheet metal bending products. Background Art

[0002] Sheet metal is a comprehensive cold processing technology for thin metal plates, including shearing, punching / cutting / combining, folding, welding, riveting, splicing, forming, etc. Its notable feature is that the thickness of the same part is consistent. The products processed by the sheet metal industry are called sheet metal parts. Sheet metal parts have the characteristics of light weight, high strength, conductivity (can be used for electromagnetic shielding), low cost, good performance in large-scale mass production, etc., and have also been widely used in the field of home appliances.

[0003] After massive searches, it was found that the prior art publication number is CN220362191U, which discloses a sheet metal welding fixture, including a working platform and a fixture unit, which is symmetrically installed on the upper end of the working platform. When in use, the utility model can use the output shaft of the cylinder to push out the clamping end, so that the abutment block of the clamping end can be clamped with the sheet metal, mainly by first abutting against the upper and lower surfaces of the sheet metal through a movable abutment plate, and during continuous clamping, the movable abutment plate will gradually align with the abutment block, and the sheet metal will be fixed through the sides of the two. Because a spring is also provided between the side surfaces of the movable abutment plate and the fixed plate, the spring will be pulled when the movable abutment plate is squeezed, and when the abutment block is flush with the side surface of the movable abutment plate and abuts against the surface of the sheet metal, because the spring will continue to contract and cause the movable abutment plate to tilt, the movable abutment plate can swing with its connection end with the abutment block as a fulcrum, so that the upper part of the movable abutment plate is squeezed against the sheet metal, thereby increasing the fixing effect of the sheet metal.

[0004] In summary, sheet metal parts are welded after being bent, but there may be deviations in the weld position at the bend, which will adversely affect the welding quality.

[0005] In view of the above-mentioned defects, the designer actively carried out research and innovation in order to create a sheet metal bending product welding tooling to make it more valuable for industrial use. Utility Model Content
