Problems solved by technology

[0002] In the field of heavy-duty vehicles, the door frame of general heavy-duty trucks is a split welding structure, which is welded by split welding. It is not suitable for the new type of overall structure door frame, because the quality of the door frame of this structure is better. However, the shape is complex, and its stamping process requires high and complicated
At present, there is no high-efficiency and stable-quality process for the overall structure of the door frame in the prior art, which cannot meet the technical and quality requirements of its products.
