我公司生产的双列圆锥滚子轴承外套，其成品尺 寸如图１中括号内尺寸。该锻件重２７．５ ｋｇ，辗扩前毛坯如图２所示，其高径比为２．３，属典型的高筒类锻件。此前，国内从未批量加工过如此超高超重的大高径比的环坯锻件。 ＬＹ－８０００ ｋＮ油压机为三梁 四柱多工位模锻液
My company’s double row tapered roller bearing jacket, the finished size shown in Figure 1 brackets within the size. The forging weight 27.5 kg, before rolling out the rough as shown in Figure 2, the aspect ratio of 2.3, is a typical high-forging cylinder. Prior to this, China has never been such a large number of ultra-high-volume processing of high aspect ratio ring forgings.
