Abstract
Description
Technical Field
[0001] This utility model relates to the field of drill bit quenching technology, specifically a drill bit quenching device. Background Technology
[0002] Drill bit hardening is a heat treatment process designed to improve the hardness and wear resistance of drill bits, thereby extending their service life and increasing cutting efficiency. Hardening involves rapidly cooling a heated drill bit; common cooling methods include air cooling and oil cooling. Different cooling media and cooling rates affect the final performance of the drill bit. After hardening, drill bits typically require tempering to reduce internal stresses generated during hardening and improve their toughness.
[0003] Currently, during the quenching process of drill bits, workers typically use clamping tools to hold the drill bit, then bring it close to the heating tube for heating. After heating, the drill bit is then placed in cooling oil or water for cooling. Throughout this process, workers hold the tools, which leads to significant physical exertion. Furthermore, workers' hands are usually close to the heating tube, which may result in the risk of burns. Utility Model Content
