| Abstract: | 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. |
