Description

Technical Field

[0001] The utility model relates to the technical field of machine tool castings, in particular to a cooling device for manufacturing machine tool castings. Background Art

[0002] Cooling devices for machine tool casting manufacturing usually refer to cooling devices used in the process of producing machine tool castings. These devices are designed to control the temperature of machine tool castings to ensure that the castings do not overheat during processing. In some cases, machine tool castings need to be heat treated, such as quenching, tempering and other processes. During and after these heat treatments, cooling devices are required to cool the castings to achieve the required organizational structure and performance requirements. In this case, most of the cooling methods used for castings are coolant spray cooling. This method cools quickly and compared with other cooling methods, such as immersion cooling, spray cooling can significantly reduce energy consumption.

[0003] At present, most of the existing cooling devices for machine tool castings use spray coolant to cool down the castings. However, the cooling process is prone to uneven cooling, which in turn causes uneven surface hardness and structure. This may lead to surface quality problems such as unevenness, bubbles, pores and other defects. In severe cases, it may cause uneven thermal stress distribution, which may lead to deformation, cracking or tensile failure of the castings. Utility Model Content
