Abstract：
|
|
The experimental research on the relationship between the blank holder force and the effects of different lubricants through measuring the coefficient of friction during deep drawing.The relationship between drawing force and blank holder force is also studied.The results are drawn though two types of blanks as follows:the higher is the viscosity of a lubricant,the better is the effect of lubrication while the less is the lubricant being affected by blank holder force.As the diameter of the blank increasing,the deep drawing process will be more difficult,and the blank diameter will do less to friction coefficient.This experiment study will be useful in the selection of lubricants and in the optimization of blank holder forces in practice.
