The invention discloses a four-piece type laser tailor-welded commercial vehicle side wall door frame. The side wall door frame is formed by integrally stamping a four-piece type laser tailor-welded blank. The processing method adopts a sequential tailor-welding method and comprises the following steps that: (1) a first material sheet, a second material sheet and a third material sheet are tailor-welded into a U shape by laser; (2) the end parts of the first material sheet and the second material sheet are sheared off by adopting fine shearing equipment; and (3) the fourth material sheet is welded to an opening of the U-shaped structure through laser tailored welding. The material utilization rate is greatly increased, the material cost is reduced, and the structural light weighting is achieved; by the adoption of the four-piece laser tailor-welded plate processing method, the processing precision and quality of the four-piece laser tailor-welded blank can be guaranteed, production is easy to achieve, the economic effect is obvious, and light weight, energy conservation and environmental protection of an automobile body can be achieved.

    本发明公开了一种四片式激光拼焊商用车侧围门框,采用四片式激光拼焊坯料整体式冲压成形的侧围门框。加工方法采用分序拼焊法,步骤如下:1)将第一料片、第二料片、第三料片激光拼焊成“U”型;2)采用精剪设备剪去第一料片、第二料片的端部;3)将第四料片激光拼焊在“U”型结构的开口处。本发明大幅提升材料利用率,降低材料成本,并实现结构轻量化;采用的四片式激光拼焊板加工方法,能保证四片式激光拼焊坯料的加工精度及质量,生产上易于实现,经济效果明显,且可实现汽车车身轻量化,节能环保。
