摘要
叙述了用反挤压工艺代替多道变薄拉伸工艺生产铝合金外壳的优点。对铝合金外壳进行了工艺分析、制订了挤压件图、计算了毛坯尺寸及反挤压力。介绍了毛坯制备处理、反挤压模具结构设计及主要零件的加工技术要求。
The advantages of the production for the aluminium alloy casing with backward extruding technology replacing multi-pass ironing technology are marrated. The technological analysis is conducted, the extrusion part is formulated, the blank demension and the backward extruding force are calculated for the aluminium casing. The preparation treatment of the blank,the structure design of the backward extruding die and the manufacturing technical requirements of the main part are introduced.
