The utility model relates to a new zone induction tempering device, which comprises a base plate, a clamping block, a sprayer, a connecting block, an annular tube, a riser, an effective ring and a magnet. The base plate is connected with the clamping block, the clamping block is connected with the sprayer, and the sprayer is also connected with the connecting block, the connecting block is connected with the annular tube, and the annular tube is connected with the connecting block The vertical pipe is connected, the vertical pipe is connected with the effective ring, the effective ring is connected with the magnet, the sprayer is provided with a spray surface, and some areas of the spray surface are provided with spray holes. In view of the fact that the step is not easy to be heated and tempered by the axial alternating magnetic field induction, a new type of sectional induction tempering coil device is designed. By using the proximity effect of electromagnetic induction, the normalizing or secondary hardening phenomenon of secondary austenitizing is eliminated, and the strength of thread and adjacent area is guaranteed.

一种新型分区感应回火装置
本技术涉及一种新型分区感应回火装置。
技术介绍
准双曲面齿轮轴的热处理工艺为渗碳淬火、回火,其螺纹部份与齿面拥有同样的渗碳硬化层深及表面硬度,螺纹区域太高的硬度容易脆断,并不适用于锁紧,产品设计要求需将齿轮轴的2/3螺纹及台阶连接部份进行感应回火,使其表面硬度降至HRC45及以下,达到类似高强度紧固件等级,再用于装配的锁紧。CN103103331A公开了一种轴类零件感应淬火装置同步感应回火的方法及加热感应器,这种加热感应器,包括感应器主体,所述的感应器主体包括淬火线圈和回火线圈,淬火线圈和回火线圈相连接形成8字形结构,在感应器主体的末端上设置有绝缘板。这种淬火回火的方法为:先按常规的感应淬火工艺用淬火线圈对轴类零件进行感应淬火,喷水冷却后,感应器主体移动,使感应器主体的回火线圈的中心与轴类零件的回转中心重合,进行感应回火,回火后的轴类零件冷却后就完成了感应淬火回火工序。该方法对于普通圆柱体感应加热是均匀高效的,但对于带台阶的齿轮轴来讲,因为感应加热的临近效应,轴向扫掠磁力线会被台阶遮挡,则不 ...
