摘　　要：设计了拼焊板拉延成形模具结构,并对相同材料不同厚度的拼焊板方盒形件拉延工艺进行了实验研究,分析了拼焊板方盒形件拉延后焊缝移动规律及壁厚变化规律。实验结果表明,盒形件底部焊缝向厚板侧移动、侧壁处焊缝向薄板侧移动的焊缝移动规律。The die structure was designed. Deep drawing of square part of tailor-welded blanks of the same material and different thickness was studied by experiment. The movement of the weld seam and thickness distribution were analyzed. The results show the weld seam moves towards the thick part on the bottom of the square boxes and towards the thin part on the wall of the square boxes.
