摘　　要：介绍了铝管的冷挤压成形工艺和经冷挤后的光整加工工艺。设计了冷挤压成形模具及挤光模。采用该工艺及模具，使材料利用率和生产效率大大提高，挤光后零件表面质量相当好。In this paper, it take two cold extrusion steps to manufacture 170 mm/160 mm×310 mm 5A02(LF2)aluminium alloy tube with high surface finish and high precision. In the first step, it is extruded from 181/149 mm block into 170/160 mm tube. In the second step, it is obtained with high surface finish and high precision through cold extrusion. The results showed that the processing is practicable.
