Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of medium frequency heat treatment of bell-shaped shells, and particularly relates to a shielding ring tool for medium frequency heat treatment of the inner cavity of a bell-shaped shell of a driving shaft. BACKGROUND

[0002] During induction quenching of the inner cavity of the bell-shaped shell of the driving shaft, in order to shield the current overflow during quenching of the inner cavity of the bell-shaped shell, the mouth of the inner cavity of the bell-shaped shell is easily quenched, which causes the heat treatment quality of the bell-shaped shell to fail to meet the predetermined requirements. Therefore, a manual sleeving type shielding ring has been used to assist in medium frequency heat treatment of the inner cavity of the bell-shaped shell. However, this shielding method increases the workload of the operator, and each part needs to be manually sleeved with the ring for processing. After processing is completed, the shielding ring is removed. In addition, there is a risk of missing the shielding ring, which causes the mouth of the bell-shaped shell to penetrate, and there is a serious safety and quality risk. Therefore, the present application provides a shielding ring tool for medium frequency heat treatment of the inner cavity of the bell-shaped shell of the driving shaft. SUMMARY
