新一代的高铁接触线将采用锆铬铜合金/复合线材(铜包钢)。现有的高铁接触线生产工艺不太适应于锆铬铜合金/铜包钢线料，为此本文介绍压力模拉拔工艺，从粘性力学的角度对压力模拉拔过程进行数学分析，找出增加的压力与压力模几何尺寸、拉拔速度、润滑油动力粘度之间的关系，实验表明当变形区锥角及拉拔速度相同时，使用压力模比普通模的拉拔力降低15%ц32%。

Contact wire of new generation used in high speed railway line is composed of Cr-Zr cop-per alloy/composite materials ( such as copper clad steel wire) . Production process of existing con-tact wire is not suitable for producing Cr-Zr copper alloy/copper clad steel wire. In order to solve this problem, pressure die technique to experimentally draw contact wire is introduced and the rela-tion between increased pressure and geometry dimension, pulling speed, dynamic viscosity is ana-lyzed via the principle of viscous mechanics. The experiment shows that pulling force is reduced by 15% ц32%, under the same reduction angle and speed.
