Description

Technical Field

[0001] The utility model relates to the technical field of galvanized steel pipe spraying, in particular to a spraying device for processing galvanized steel pipes. Background Technique

[0002] Galvanized steel pipe is a very important component material, which is widely used in various industries such as construction, machinery, electric power, automobile industry, highway, and bridge. It is composed of a steel pipe itself, and a layer of zinc is plated on its surface to improve the corrosion resistance of the steel pipe and extend the service life of the steel pipe. In order to further improve its corrosion resistance, it is also necessary to spray an anti-corrosion material on the outer surface of the galvanized pipe.

[0003] When the existing spraying device for processing galvanized pipes sprays steel pipes, the loading and unloading operations are relatively troublesome. Workers need to bind and clamp the steel pipes in advance, and then carry them into the spraying area for spraying. After spraying, since the paint on the surface is not dry, it needs to be left standing for a period of time until the paint dries before it can be disassembled and removed. Then, a new galvanized steel pipe is replaced for spraying. During this process, due to the long waiting time, the spraying operation is in a stagnant state, and the work of disassembling and re-fixing the workpiece is relatively cumbersome and takes a long time. Therefore, a lot of time is wasted, the processing efficiency is seriously reduced, and the production work time is delayed.

[0004] Therefore, in view of the fact that the existing spraying device for processing galvanized pipes has relatively troublesome loading and unloading operations, is cumbersome, takes a long time, and wastes more processing time due to the need to wait for the surface paint of the workpiece to dry, resulting in a long processing cycle, a large workload for workers, and low production efficiency, a spraying device for processing galvanized steel pipes can be designed. It can facilitate the rapid connection of workpiece loading and unloading. During the process of spraying the workpiece in the upper part, the preparation work of the workpiece to be sprayed in the lower part is prepared, realizing the rapid connection after the workpiece is sprayed, reducing the cumbersome operations of removing and replacing the workpiece, and also reducing the impact on processing caused by the standing of the workpiece after spraying, making full use of time, reducing the wasted time cost, improving the processing efficiency, and improving productivity. Content of the Utility Model
