摘　　要：某航空设施上铝合金连接套采用反向冷挤压方式加工,与传统车削加工方式相比,前者省时、省工、省材料、省能源消耗;特别是利用自主开发的反向冷挤压模具,可以巧妙地解决铝合金套脱模问题和压制过程中的开裂、掉皮等表面质量问题。这种冷挤压方式创新了铝合金连接套的制造方式,大幅度提升了产品生产效率和产品质量,原材料节省率超过50%,非常值得推广。The aluminum alloy connecting sleeve on an aviation facility is processed by reverse cold extrusion, which saves time, labor,materials and energy consumption compared with the traditional turning method. In particular, the self-developed reverse cold extrusion die can be used to solve the peeling problem of aluminum alloy sleeve and surface quality problems such as cracking and peeling in the process of pressing. This cold extrusion method innovates the manufacturing method of aluminum alloy connecting sleeve,greatly improves the production efficiency and product quality, and saves more than 50% of raw materials, which is very worthy of promotion.
