Description

Technical Field

[0001] The utility model relates to the field of workpiece galvanizing, in particular to a clamping device used for galvanizing of electric power workpieces. Background Art

[0002] Galvanizing refers to a surface treatment technology that coats a layer of zinc on the surface of metals, alloys or other materials for aesthetic purposes and to prevent rust. The main method used is hot-dip galvanizing. Zinc is easily soluble in acid and alkali, so it is called an amphoteric metal. Zinc hardly changes in dry air. In humid air, a dense basic zinc carbonate film will form on the surface of zinc. In sulfur dioxide, hydrogen sulfide and marine atmospheres, zinc has poor corrosion resistance, especially in high temperature, high humidity and organic acid atmospheres, the zinc coating is easily corroded. The standard electrode potential of zinc is -0.76V. For steel substrates, the zinc coating is an anodic coating. It is mainly used to prevent the corrosion of steel, and the quality of its protective performance is closely related to the thickness of the coating. After passivation, dyeing or coating with a light protectant, the zinc coating can significantly improve its protective and decorative properties;

[0003] In the prior art, the holding rods are moved so that the holding rods are plugged into the two ends of the steel pipe to clamp the steel pipe, and the steel pipe is moved into the galvanizing pool by the clamping device to galvanize the steel pipe.

[0004] However, when the diameter of the steel pipe changes, the supporting rod cannot change accordingly, causing the steel pipe to swing between the two sets of supporting rods, affecting the galvanizing effect. Utility Model Content
