支重轮轴中频感应加热淬火保护装置
本技术适用于工程机械支重轮轴的轴肩两侧端面中频感应加热淬火时的硬度性能保护。
技术介绍
目前工程机械的支重轮轴,其特点是轴肩两侧端面与轴面进行中频感应加热淬火时,由于轴肩比较薄,对支重轮轴的轴肩一侧端面与之相连的轴面进行中频感应加热淬火时,轴肩的另一侧端面会由于感应加热的热量传递导致其端面硬度明显降低,影响了零件质量。
技术实现思路
本技术的目的在于克服上述技术的不足,而提供的一种工程机械支重轮轴中频感应加热淬火保护装置,它可以有效地解决支重轮轴比较薄的轴肩一侧端面和相连的轴部进行中频感应加热淬火时,因热传递将导致轴肩的另一侧端面硬度降低的质量问题。本技术为实现上述目的,采用以下技术方案:支重轮轴中频感应加热淬火保护装置,由感应器有效圈、淬火冷却圈、保护水圈、绝缘垫圈Ⅰ、连接板、绝缘垫圈Ⅱ、铜垫圈、铜螺杆和铜螺母组成。其特征是感应器有效圈与连接板焊接,保护水圈、铜螺杆焊接在淬火冷却圈上,绝缘垫圈Ⅰ、连接板、绝缘垫圈Ⅱ、铜垫圈通过铜螺杆用铜螺母锁紧。使用时先将支重轮轴中频感应加热淬火保护装置与机床上的淬火变压器连接,待感应加热淬火支重轮 ...
