| description | The invention discloses a forging method for refining the grain size of a GH4169 ring forging by using a 1T electro-hydraulic hammer, which is used for producing a gland nut on an aero-engine and comprises the following steps: blanking; the method comprises the steps of inner hole turning, rounding, heating, first-fire forging, hot blank remelting and heating, second-fire forging, hot blank remelting and heating, third-fire forging, hot blank remelting and heating, finish forging forming and physical and chemical detection. The forging technology of the ring forge piece solves the problems that (1) the average grain size of the forge piece is refined; and (2) the qualified rate of finished products of the ring forgings is improved.
本发明公开了一种用1T电液锤细化GH4169环锻件晶粒度的锻造方法，用于生产航空发动机上的压紧螺母，包括如下步骤：下料→机加，车内孔→倒圆角→加热→1火锻造→热坯回炉加热→2火锻造→热坯回炉加热→3火锻造→热坯回炉加热→终锻成型→理化检测。本发明环锻件锻造技术解决了：(1)细化锻件平均晶粒度。（2）提高环锻件的成品合格率。 |
