Technical Field

[0001] The utility model relates to the technical field of automobile stamping parts processing equipment, in particular to an automobile stamping parts corner welding device. Background Art

[0002] Cars are assembled from numerous auto parts, among which auto parts are mainly divided into castings and stampings. Most of the castings are cast one-piece components, while stampings are generally stamped from steel plates. In the process of stamping steel plates, since many stamping parts have complex structures, if they are directly stamped in one go, extremely high performance requirements are placed on the punch press and stamping die. In addition, the more complex the stamping parts are, the more likely they are to get stuck during the stamping process. Therefore, in the actual production process, many stamping parts are divided into multiple stamping components, which are then welded together;

[0003] At present, welding between stamping parts is generally performed by experienced welders or using welding machines. However, welding by welders greatly increases labor costs and has low welding efficiency. Although welding efficiency is improved by using welding machines, a certain inclination angle is left at the corners of the stamping parts during the stamping process to facilitate demoulding. However, due to the existence of the inclination angle, the corners of the two stamping parts will be poorly welded, seriously affecting the welding quality. Therefore, the utility model proposes a corner welding device for automobile stamping parts to solve the above problems. Utility Model Content
