本文主要介绍采用探针测定拉深过程中的摩擦系数。并与其它常用的方法进行对比。得出的结论是,探针方法可测出变形区域内任意一点的正压力和摩擦系数,且在计算摩擦系数公式中没有任何假设条件,还可测出在压边圈范围内整个金属变形过程中的摩擦系数和平均摩擦系数。试验证明。一旦掌握了利用探针测定拉深过程中的摩擦系数,就可减小测试和计算过程中的人为和其它因素影响。因此可提高测试精度,误差也相对地减小。
This article describes the use of probes to determine the friction coefficient during drawing. And compared with other commonly used methods. The conclusion is that the probe method can detect the positive pressure and the friction coefficient at any point in the deformation area and there is no assumption in calculating the friction coefficient formula and the whole metal deformation process In the friction coefficient and the average friction coefficient. Test proved. Once you have mastered the use of probes to determine the friction coefficient during drawing, you can reduce the impact of human and other factors in testing and calculation. So can improve the test precision, the error is relatively reduced too.
