摘　　要：液压柔性冷拔工艺是一种新型的钢管冷加工工艺,旨在提高管材尺寸精度和表面粗糙度。本文在柔性拔制原理的基础上,提出新的模具方法,并针对Φ30管材拔制模具进行设计。运用Deform-3D有限元软件模拟了不同油压下新型冷拔模具空拔成形过程。得到拔制过程中各量场分布,研究了拔制力的变化规律,分析了不同油压对拔制力的影响。使用新型模具在不同油压下进行拔制实验,测得拔制力变化曲线,表面粗糙度变化情况。Hydraulic flexible cold drawing process is a new kind of steel tube cold working process, it aimed atimproving the dimensional accuracy and surface roughness of pipe. In this paper, based on the principle of flex-ible drawing, new mould method is put forward, and Φ30 tube drawing die design. Using Deform-3D finite el-ement software, a simulation analysis of the new die empty-drawing process under different oil pressure is putforward. Get the drawing process is the amount of each distribution studied drawing force variation, and analy-zes the impact of oil on different drawing force. Using the new mould drawing experiments under different oilpressure, measured curves of drawing force, surface roughness changes.
