Description

Technical Field

[0001] The utility model relates to an air-cooled device with rotation, belonging to the technical field of cooling devices. Background Technique

[0002] Carburizing of workpieces refers to the process of infiltrating carbon atoms into the surface layer of steel. It also makes the workpieces of low-carbon steel have a surface layer of high-carbon steel, and then through quenching and low-temperature tempering, the surface layer of the workpieces has high hardness and wear resistance, while the central part of the workpieces still maintains the toughness and plasticity of low-carbon steel.

[0003] In the current prior art, after the workpieces are carburized, in order for the workpieces to reach the required hardness, they need to be cooled by a fan to discharge the heat of the workpieces. Conventional fan cooling uses a well-type air-cooling tower to cool the workpieces, and the existing well-type air-cooling tower is a single-opening fixed structure. When cooling the workpieces, the carburized workpieces are hoisted into the upper opening of the air-cooling tower, and an air-sucking fan is arranged at the upper opening of the air-cooling tower to suck out the heat in the air-cooling tower. However, in such a cooling method, since the air is sucked at the upper opening of the air-cooling tower for cooling, the heat of the workpieces is uneven up and down, resulting in inconsistent hardness of the workpieces, affecting the quality of the workpieces, and the cooling time is long. Therefore, an air-cooled device is needed to solve the problems that when the existing fixed air-cooling tower is used for cooling after the workpieces are carburized, the heat of the workpieces is unevenly cooled up and down, affecting the quality of the workpieces and the long cooling time.
