用KD KS 方法设计圆管拉拔配模时经验参数ΔD 和ΔS 的值 ,已能将经验和理论结合起来进行选取 ;并对计算结果“不到位” ,提出了 4种修正方法。ΔD 对ΔD .max 和ΔS 对ΔS .max的比值是ΔD 和ΔS 取值是否合理的判据。ΔD 值和ΔS 值的选取 ,除了要使计算结果“到位” ,还应该考虑圆管的材质和工艺条件及其要求
Using the KD KS method to design the parameters of ΔD and ΔS for the drawing and drawing of circular tubes, we can combine the experience and theory to select them. And we give four kinds of correction methods for the calculation result “not in place”. The ratio of ΔD to ΔD.max and ΔS to ΔS.max is a criterion of whether ΔD and ΔS values are reasonable. ΔD value and ΔS value of the selection, in addition to make the calculation results “in place”, but also should consider the pipe material and process conditions and requirements
