本实验研究探讨了坯料形状,润滑条件对盒形件拉深成形极限的影响,对此作了一些理论分析,提出了提高盒形件一次拉深成形极限变形程度的措施和方法,并给出了经验公式与实验数据。
In this experiment, the influence of the billet shape and lubrication conditions on the drawing forming limit of box-shaped parts was discussed. Some theoretical analyzes were made, and some measures and methods to improve the deformation limit of the box-shaped parts in one-step drawing were put forward. Empirical formula and experimental data.
