Description

Technical Field

[0001] The utility model relates to the technical field of galvanizing equipment, in particular to hot-dip galvanizing auxiliary plating equipment. Background Art

[0002] The disc-type steel scaffolding needs to be hot-dip galvanized during production. It needs to be treated by pickling-water washing-plating equipment before hot-dip galvanizing. The plating treatment helps to remove the oxide scale generated by the re-oxidation of the parts after pickling and cleaning, as well as the steel matrix that has not been fully activated and the molten metal oxide. This can reduce the surface tension of the matrix, increase the surface activity, and promote the wetting effect of the plating solution and the matrix.

[0003] The existing auxiliary plating method is to put the workpiece into the auxiliary plating tank liquid for immersion. The solution in the auxiliary plating tank is usually a mixture of zinc chloride and ammonium chloride. The main function of zinc chloride is to form a protective film to reduce the oxidation of the workpiece from pickling to hot-dip galvanizing, while ammonium chloride can reduce the residual iron oxide on the surface of the workpiece. In this immersion process, since the static auxiliary plating tank liquid does not have a flow effect, the steel workpiece is only in continuous contact with part of the auxiliary plating tank liquid. As time goes on, the concentration of the auxiliary plating tank liquid decreases, and the effect on the formation of the protective film and the decomposition of the oxide layer becomes worse. In addition, it is difficult for the static auxiliary plating tank liquid to remove zinc slag and other impurities attached to the surface of the workpiece. Utility Model Content

[0004] The utility model aims to provide a hot-dip galvanizing auxiliary plating equipment to solve the problem that the existing auxiliary plating method proposed in the above background technology is to put the workpiece into the auxiliary plating tank liquid for immersion, and in this immersion process, because the static auxiliary plating tank liquid does not have a flow effect, the steel workpiece is only in continuous contact with part of the auxiliary plating tank liquid, and as time goes by, the concentration of the auxiliary plating tank liquid decreases, the formation of the protective film and the decomposition of the oxide layer become worse, and the static auxiliary plating tank liquid is difficult to remove the zinc slag and other impurities attached to the surface of the workpiece.

[0005] In order to achieve the above purpose, the utility model provides the following technical solutions:

One end of a buffer spring is fixedly connected to the side wall of the limiting plate, and the other end of the buffer spring is fixedly connected to a positioning block.

[0013] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0014] 1. The driving motor can drive the first rotating shaft to rotate, so as to drive the first bevel gear set to rotate meshingly. The first bevel gear set can drive the rotating column located in the middle to rotate. Under the action of the double-groove pulley and the synchronous belt, the three rotating columns can be synchronously driven to rotate. The plurality of stirring plates can be driven to rotate by the plurality of sleeves on the outer wall of the rotating column, so as to stir the zinc plating bath liquid in the zinc plating assisting tank, make the zinc plating bath liquid flow, increase the contact between the zinc plating bath liquid and the steel workpiece, avoid the decomposition effect of the oxide layer caused by the long-term contact between the steel workpiece and part of the zinc plating bath liquid, and the flowing zinc plating bath liquid can more evenly cover the surface of the steel workpiece, ensure that the zinc plating agent can fully penetrate into every corner and gap on the surface of the workpiece, which helps to achieve a uniform zinc coating thickness and improve the zinc plating quality.

[0016] 3. The first rotating shaft can drive the second bevel gear set at the top to engage and rotate, and then the second bevel gear set drives the middle second rotating shaft to rotate, so that the second rotating shaft can drive the turntables at both ends to rotate, so that the turntables can drive the拨动 rods to slide in the chute rods, thereby driving the sliding columns to slide on the galvanizing assistant tank. Therefore, the moving frame can slide reciprocally on the limiting columns, so that the scaffolding steel pipes slide reciprocally between the two limiting plates, so as to cooperate with the flowing galvanizing assistant bath to effectively reduce possible defects in the galvanizing process, such as zinc nodules, zinc slag, etc. Shaking the workpiece can help the galvanizing assistant bath to wash away the iron salts and other impurities on the surface of the workpiece. After shaking, these impurities quickly fall off, so that the surface of the steel workpiece can be fully contacted with the galvanizing assistant bath, promoting the formation of the protective film and the decomposition of iron oxide, thereby improving the adhesion and corrosion resistance of the galvanized layer.
