2618A、2214、7075 铝合金锻件的等温锻造

Isothermal Forging of 2618A,2214 and 7075 Aluminium Alloy Pieces

通过对某机的主起落架接头、作动筒接头、主起落架外筒、前起落架外筒、旋转盘、固定盘等关键锻件的工艺分析，阐述了２６１８Ａ、２２１４、７０７５铝合金锻件的等温锻造工艺。

On the basis of the process analysis of important forged pieces for an helicopter,such as the joints of main landing gear and actuating cylinder,the extermal cylinders of main and nose landing gears,and the rotating and fixed plates,the isothermal forging processes for the 2618A,2214 and 7075 aluminium alloys have been treated.
