Description

Technical Field

[0001] The invention relates to the technical field of sheet metal welding processing, in particular to a large sheet metal welding device with an automatic flipping function. Background Art

[0002] Sheet metal parts are metal parts processed by sheet metal processing. Sheet metal processing is a comprehensive cold processing technology for metal sheets, including shearing, punching / cutting / compounding, folding, riveting, splicing, forming (such as car bodies), etc. The parts made by these processes are called sheet metal parts. Sheet metal parts have the characteristics of light weight, high strength, low cost, and good performance in large-scale mass production. They are widely used in electronics, communications, automotive industry, medical equipment and other fields. For example, computer case shells, car body covers, electrical cabinets, etc. are all sheet metal parts.

[0003] The existing processing technology is to cut, bend and other cold processing methods on the plate to form the required shape of the parts, then manually assemble and spot weld, and finally fully weld. In the welding process, since the places that need to be welded involve various places such as the surroundings, inside and outside of the workpiece shell, the existing welding process requires the workpiece shell to be lifted by lifting equipment. In the above situation, manual welding will be limited by the space of the workpiece shell, resulting in low welding efficiency and great welding difficulty. At the same time, it is difficult for the lifting equipment to flip the workpiece shell by lifting, and the workpiece shell is easily damaged when flipping.
