摘要
设计了专用定位工装和两种镶装Π形硅钢片的U形感应器A和B。在频率8~20 kHz,最大输出功率300 kW的全自动淬火机床上,利用感应器A和B,在外喷淋保护的条件下对三柱槽壳内花键进行感应淬火试验。结果表明:采用只以内孔和端面定位的方式,结合镶装Π形硅钢片的U形感应器,在外表面保护喷淋的条件下进行感应淬火,可以满足三柱槽壳内花键的淬火要求,且B型感应器比A型感应器的加热功率系数低,总加热时间短,节能增产效果显著。合理的感应器设计是三柱槽壳内花键感应淬火节能、增产的有效途径。
Special positioning tooling and two kinds of U-shaped inductors A and B withΠ-shaped silicon steel sheet were designed.The induction hardening test of internal spline in tulip was carried out by using inductor A and B under the condition of spray protection of outer surface on the fully automatic quenching machine with frequency of 8-20 kHz and maximum output power of 300 kW.The results show that by using the method of positioning only the inner hole and end surface,the induction hardening is carried out with the U shaped inductor withΠ-shaped silicon steel sheet under the condition of protective spraying on outer surface,which can meet the quenching requirements of internal spline in tulip.Compared with A type inductor,the heating power coefficient of B type inductor is lower,the heating time is shorter,and the energy saving and production increasing effect is more remarkable,which shows that the reasonable inductor design for the induction hardening of internal spline in tulip is an effective way for energy saving and production increasing.
