摘　　要：利用探针法探讨了Ｓｔ１４钢板在拉深过程中凸缘处的摩擦与润滑规律，根据实验结果分析了拉深成形过程中的摩擦特征．结果表明，随着压边力的增加，摩擦系数基本保持恒定；拉深坯料尺寸增加，拉深力将增加．加入粘度较小的润滑油可以在较小拉深力和压边力的工艺条件下完成拉深成形．Probe test method that can reflect disciplinary of friction and lubricate in deep drawing factually is proposed and the friction character in deep drawing is analyzed based on the experiment results. The deformation characteristic of blank during deep drawing is discussed. Friction issue in deep drawing is investigated; the progress in tribology investigation of metal blank deep drawing is analyzed. The result that better lubricate will do good to drawing successful with small punch force and blank holder force is point out.
