摘要
在分析经典资料介绍的盒件拉深成形极限和毛坯制定法的基础上进行了方盒件的拉深研究，实验得出了方盒件单工序成形的更高极限值，提出了一种较为合理的新的毛坯制定法———“三参数法”。
After analysis of classical material, the forming limits and billet designing of box drawing are studied in this paper. The experiments on box drawing were carried out. The higher forming limits and more reasonable design method of billet are suggested. It is of great value to increase once forming limits in the practice.
