Description

Technical Field

[0001] The utility model specifically relates to the technical field of connecting piece processing, in particular to a quenching device for connecting pieces of a crane. Background Art

[0002] A crane is a mechanical device used to move heavy objects. When the crane is working, its connectors are subjected to alternating loads. For example, when the crane is lifting a heavy object, the connectors are subjected to tensile stress. When the object falls to the ground, the stress disappears. Such repeated stress changes can cause fatigue in the connectors. Therefore, these connectors require higher hardness. In metal processing, quenching is usually used to obtain higher hardness.

[0003] The workpiece is heated to a critical point or above a certain temperature using a heating coil, and then cooled at a rate greater than the critical cooling rate after insulation. Cooling water is generally used to quench the heated workpiece.

[0004] However, in practice, people have noticed that a large amount of water is consumed during quenching, and placing the heated workpiece directly into the cooling water will cause the temperature of the cooling water to rise rapidly. The cooling water needs to be lowered to the specified temperature when it is used again, otherwise it will not have a good quenching effect. The spray-type quenching equipment will cause a large amount of cooling water to fall to the outside of the water tank, causing waste and leading to higher processing costs. Utility Model Content
