Abstract

The invention discloses a galvanized part passivation device and relates to the technical field of galvanizing devices. The galvanized part passivation device comprises a spray head used for sprayingpassivation liquid to the surface of a round tube, a clamping mechanism used for clamping the two ends of the round tube and guide rails slidably connected with the clamping mechanism. The clamping mechanism comprises a base plate slidably connected to the guide rails, clamping blocks located at the two ends of the round tube and used for clamping the round tube, locating blocks rotatably connected to the clamping blocks and inserted into the round tubes, fixed connecting mechanisms located on the locating blocks and used for realizing fixed connection between the locating blocks and the roundtube, motors used for driving the locating blocks to rotate and bearings located between the round tube and the locating blocks and used for reducing the rotating resistance of the round tube. Through the galvanized part passivation device provided by the invention, passivation liquid cannot go into the ends of the round tube, passivation is uniform, and the stability is good.

Description

technical field [0001] The invention belongs to the technical field of galvanizing devices, in particular to a passivation device for galvanized components. Background technique [0002] After the round pipe is galvanized, passivation is required to improve corrosion resistance. [0003] At present, the passivation of round pipes is mostly the spray method, that is, the passivation solution is sprayed on the surface of the steel pipe from the nozzle, and then the passivation solution is blown evenly under the action of the air knife. [0004] During the passivation process of the above round tube, some passivation solution will enter the port of the round tube, resulting in a small amount of passivation solution remaining, which will affect the appearance quality of the product, increase the consumption of passivation solution, and increase the production cost . Contents of the invention [0005] The object of the present invention is to overcome the shortcoming of the p...
