摘要
对于偏心距离大,凹档长度长,轴颈部位直径变化较大的偏心轴,锻造成形难度很大,为保证锻件尺寸,需要在锻造过程中对下料尺寸、压下量等参数进行严格控制。
For the eccentric shaft with large eccentric distance,long concave length and great variation of shaft neck diameter,forging forming is very difficult. In order to ensure the forging size,it is necessary to strictly control the blanking size and the reduction amount in the forging process.
