大型锻件轴的校正与修复工艺

Repair of Large Forged Shaft

本文根据修复变形的中间轴和尾轴案例,叙述了大型锻件轴变形后的手工修复过程。通过对轴表面检查、磁粉探伤,初步判断轴的可修复性。进一步对轴弯曲量进行检测、数据处理、弯曲状态分析,对各个过程作了详细的说明。通过一系列的实践证明,使用手工敲击的方法校正大型锻件轴是经济可行的。

This paper describes the manual repair process after the deformation of the large forged shaft according to the successful repair cases of intermediate shaft and tail shaft.By checking the surface and magnetic particle method,the repairability of the shaft is preliminarily judged.Then,the measurement,data processing,bending state analysis of the shaft bending amount are made,the shaft is repaired by manual striking,and each process is described in detail.Through a series of practice,it is economical and feasible to repair the large forged shaft by manual striking.
