摘　　要：由于风机空心主轴的法兰直径大且长度短,法兰成形难度大,坯料利用率不高。通过改变胎膜形状,由法兰端冲孔改为从小头端冲孔,将四火次的工序改为两火次完成,最终得到质量稳定、满足用户要求的锻件。Due to the large diameter and short length of the flange of the hollow spindle of the wind driven generator,it is difficult to form the flange and the utilization rate of the blank is not high.By changing the shape of mold,and changing the punching from the flange end to that from the small head end,and changing the four-fire process into two-fire process,the forging has stable quality and meet user’s requirements finally.

关 键 词：空心主轴 法兰 利用率 冲孔
