Description

Technical Field

[0001] The utility model relates to the technical field of drill rod production equipment, in particular to a fixing device for heat treatment of the tip of a drill rod. Background Art

[0002] A drill rod is a specialized tool installed on a hydraulic breaker. The impact energy generated by the breaker's piston is transferred to the object being broken by striking the drill rod, causing it to crack and break. The drill rod is the medium for energy transmission and is subject to the piston's impact force and the reaction force of the object being broken during operation.

[0003] The drill rod production process requires raw material preparation, material processing, heat treatment and surface treatment. The heat treatment process is to improve the hardness and strength of the drill rod, while improving the organizational structure of the drill rod, reducing internal stress and increasing corrosion resistance. Common heat treatment processes include annealing, normalizing and quenching. The specific process to be selected depends on the material and requirements of the drill rod.

[0004] During the heat treatment production process, workers are generally required to transport the clamped drill rods to the heat treatment area, which consumes a lot of manpower costs. In addition, the temperature in the heat treatment workshop is generally high, which makes it easy to get heatstroke in the summer. At the same time, most clamping equipment usually has a large amount of heat treatment temperature of the drill rod transferred to the equipment itself during the heat treatment process, which affects its service life.

[0005] Currently, no effective solutions have been proposed for the problems in related technologies. Utility Model Content
