摘要
文章介绍了以外径减缩系数Ｋ_Ｄ和壁厚减缩系数Ｋ_ｓ为中心的“Ｋ系列参数”，它对分析拉拉圆管配模设计具有实用价值。文章提出了拉拔有色金属圆管的Ｋ系列参数的“极限值”数据，可供具体配模设计时参考。文章对Ｋ系列参数的应用作了初步探讨。
This paper introduces 'K series parameters' centering around K_D (the OD reducing coefficient) and Ks (the wall thickness reducing coefficient), which will prove practically valuable for analysing die matching design. The'ultimate figures' of 'K series parameters'for draw- ing round non-ferrous tubes are given as reference for die matching design. The application,of 'K series parameters' are preliminarily studied. Keywolds: Drawing round tube.OD Reducing coefficient,Wall thickness reducing coefficient, Die matching design
