摘　　要：拼焊板由于两侧材料差异导致成形性能下降。利用有限元模拟分析得到,采用焊缝夹紧装置能提高拼焊板成形性能。根据有限元分析结果,设计了具有液压夹紧装置的盒形件模具,并进行了实验研究。结果表明:有限元模拟能准确模拟拼焊板成形过程,带焊缝夹紧装置的模具能提高拼焊板的成形性能。所设计模具操作简单、可靠,可为同类模具设计提供参考。The tailor welded blank has poorer formability due to the material difference. The formability of rectangular cup with tailor welded blank can be improved by weld clamping in FEA simulation and analysis. Based on the FEA simulation results, the die of rectangular box containing weld clamping system was designed. Then the experiment is operated. The results show that FEA simulation predict tailor welded blank forming well and the formability of rectangular box with tailor welded blank is improved by weld clamping system. The die designed can be operated easily and effectively. This structure of die can be used in other similar die.
