Description

[Technical field]

[0001] The invention relates to the technical field of nut production equipment, in particular to the technical field of a low-temperature resistant coating device for railway hexagonal nuts. [Background technology]

[0002] A nut is a nut that is screwed together with a bolt or a screw for fastening. It is a component that all manufacturing machinery must use. According to the different materials, it is divided into several types, such as carbon steel, stainless steel, and non-ferrous metals (such as copper). During the installation of railway tracks, construction workers need to use bolts and nuts to fix the railway tracks on sleepers so that the railway tracks can be installed firmly. Railway tracks are installed outdoors and are easily affected by the low temperature external environment and produce expansion and contraction deformation, which causes the fit between the bolts and nuts to loosen or even fall off. Coating a low-temperature resistant coating on the surface of the nut can effectively reduce the impact of temperature changes on the nut structure and improve the connection stability of the nut in a low-temperature environment. Therefore, it is extremely necessary to design a low-temperature resistant coating device for railway hexagonal nuts. [Summary of the invention]
