中间轴锻造工艺优化

Optimization of Forging Process of Intermediate Shaft

针对传统自由锻造工艺生产中间轴等非对称大法兰空心轴类件时,容易在法兰侧出现较为严重的偏摆和内孔凹心现象,影响最终锻件尺寸,坯料利用率低的缺点。介绍一种改进锻造工艺,在利用现有附具基础上,可有效克服中间轴锻件两端面内孔凹心、法兰长短面及其端面偏摆等技术难点,最终得到满足尺寸要求的锻件。

When producing the large asymmetrical flange etc hollow shaft parts Wlth the ednventional open die forging process, the flange Side of hollow shaft part is very likely irregulai offset and which may affectthe Size of final forging and reduees the utilization rate of ingot. In this paper, a new forging process of intermediate shaft based on existing auxiliary tools is described and the confining of flange side center, end face deflection and offset irregularity of flange side were effectively improved and forging part with good size was obtained finally.
