[0002] In vehicle manufacturing, aluminum alloy castings are usually used for the keel structure of the vehicle body. These castings usually adopt a split structure and are formed by welding. However, the existing technology has some uncertainties in the welding process, such as defects such as pores, slag inclusions, cracks and pits. These defects not only affect the appearance of aluminum alloy castings, but also significantly reduce their strength, thereby affecting the bearing pressure performance and impact resistance of the vehicle body keel.

[0003] Prior art such as CN211727846U discloses a split welding arc-starting device, which improves the efficiency of disassembly and assembly of the arc-starting plate through a split structure connected by bolts and nuts, and uses a replaceable aluminum arc-starting plate to reduce costs. However, this split welding device still faces the problem of welding defects during operation, and cannot completely eliminate the undesirable phenomena during the welding process, resulting in unstable product quality.

[0004] In addition, in order to enhance the overall structural load-bearing capacity and impact resistance of the aluminum alloy casting and to more firmly fix the front windshield in the groove of the aluminum alloy casting, the prior art requires that the groove of the aluminum alloy casting be processed for overall curvature. Usually, this processing relies on manual operation, by placing the aluminum alloy casting on a suspended bracket and squeezing its groove with a heavy pressure wheel. Such operation is not only labor-intensive, but also difficult to ensure the uniformity and accuracy of the curvature, thus affecting product quality. Therefore, it is urgent for those skilled in the art to design a new type of aluminum alloy casting production bending device. Summary of the invention
