摘　　要：高精度管材是一种内表面质量要求很高,内径尺寸允许偏差很小的管材。研究了高精度管材拉拔模具形式对管材生产的影响。开发了一种新型芯棒,利用MSC.MARC有限元仿真软件,模拟高精度管材的拉拔过程,分析了新型芯棒对高精度管材尺寸精度的影响规律,为研究和生产提供有效的帮助。The hi-pressure steel tubular product has to be satisfactory to relevant very stringent requirements for internal surface quality and I.D. tolerance. The influence of the type of process tools on the manufacture of the tube is investigated. Based on the result, a new type mandrel is developed. With the MSC.MARC FE simulation software, the drawing process of the hi-precision tube is simulated, and the law of the influence of the said mandrel on the geometric tolerances of the tube is analyzed, which are considerable helpful to the research and production of the hi-precision tube.
