摘　　要：本文对拼焊板方盒件的拉深成形进行了试验研究。试验中采用了整体压边圈和分瓣压边圈。凹模表面和型腔加工了台阶以补偿坯料的厚度差值。对压边力的控制采用了弹性橡胶控制法和刚性直接控制法。对压边力的分布采用了均匀压边力和局部改变压边力。通过调整模具结构和压边方法及压边力分布 ,对坯料不均匀变形规律及焊缝的移动规律、坯料的起皱规律及控制坯料不均匀变形的方法进行了探讨研究。Deep drawing experiments were carried out for tailor\|welded blank square boxes.Single blank holders and segmental blank holders were used.Steps were made on the female die surface to make up for the thickness difference of the blanks.Elastic rubber method and rigid blank holders were used to apply blank holder force with different methods.Uniform blank holder force and local blnak holder force(non\|uniform)were tried.The non\|uniform deformation behavours and the movement of the weld seams,the wrinkling of the workpieces and the methods to control the non\|uniform deformation were investigated by adjusting the die structures,the blank holding method and the blankholding force distribution.
