AI Technical Summary

⚠Technical Problem

Shaft components need to be placed upright in a furnace for tempering before assembly in a high-temperature environment, but the lack of a lifting position makes lifting difficult.

⚗Method used

Design a furnace tempering auxiliary lifting device for shaft-type structures, including a circumferential non-closed lifting ring and an anti-detachment ring structure. The circumferential non-closed lifting ring is sleeved on the shaft-type structure through an opening, and the anti-detachment ring structure is detachably connected to the lifting ring to form a closed area, thereby realizing the circumferential positioning and preventing the shaft-type structure from falling off.

🎯Benefits of technology

It enables stable lifting and furnace quenching of shaft structures in high-temperature environments, preventing them from falling off and meeting the quenching and tempering requirements of shaft components.
