Description

A screw galvanized post-processing device

technical field

The utility model relates to the technical field of galvanizing devices, in particular to a screw galvanizing post-processing device.

Background technique

Galvanizing on the surface of the screw can increase the anti-corrosion effect of the screw. The cost of hot-dip galvanizing is lower than that of other paint layers. The principle of hot-dip galvanizing is to simply put the cleaned iron The parts, through the wetting effect of Flux, are immersed in a zinc bath, so that the steel reacts with molten zinc to form an alloyed film. In a good hot dip galvanizing operation, each process should be under strict control, and the function of the process should be fully exerted. And if the operation of the previous process is not good, it will cause a chain reaction of adverse reactions in the subsequent process, which will greatly increase the operating cost or cause poor hot-dip galvanized products. If the pretreatment is not good, the molten zinc cannot react completely with the steel to form the most perfect galvanized film structure. If the post-treatment is not good, the appearance of the galvanized film will be damaged, and the commodity value will be reduced.

At present, galvanizing of screws is generally used to directly immerse the screws to be galvanized in zinc solution to realize the coating function, so that the cooling treatment is performed after direct hot dipping. However, the galvanized surface formed in this way is easy to produce The phenomenon of uneven galvanizing affects the adhesion effect of galvanizing; and the cooling treatment after galvanizing is usually directly immersed in cold water for cooling, but the water stains on the surface of the screw cannot be effectively cleaned, which affects the service life of the screw. , Some of them include different treatment processes, but the process is cumbersome, which may easily lead to the loss and loss of screws during the treatment process.
