我厂生产的各类织机中,细长轴渗碳淬火零件数量较多。由于细长轴(L/D≥30)渗碳淬火后,全长变形大(1～5mm),表面磨削前需校直。但校直困难而费时,且常出现校直断裂现象。另外,淬火后表面硬度欠均匀,返工时废品率较高。为此,我厂对细长轴零件的渗碳淬火工艺进行了改进,在控制变形量方面取得了较好的效果。 I plant all types of looms, slender shaft carburizing quenching more parts. As the elongated shaft (L / D ≥ 30) after carburizing and quenching, the full length deformation (1 ~ 5mm), surface grinding before straightening. However, straightening difficulties and time-consuming, and often appear straightening rupture phenomenon. In addition, the surface hardness after quenching less uniform, rework higher rejection rate. To this end, I plant parts of the slender shaft carburizing quenching process has been improved in the control of deformation has achieved good results.
