摘　　要：针对铝合金XG18-2梯形管生产中存在的尺寸精度不够及表面质量低的问题,分析其产生的原因。对原生产工艺进行改进,一次拉伸成形改为过渡模拉伸成矩形后,再通过合理成形模具拉伸成形。About the size precision and the surface concave problem of the aluminium alloy XG18-2 ladder-shaped tube during its production, analyzing the cause of formation, and improving the previous die equipment production process, changing from stretching to model only once previously to stretching to retangle by transitional die first, then stretching it to expected model by reasonable forming die.

关 键 词：成形模具 铝合金 梯形管
