Description

Technical Field

[0001] This utility model relates to the field of stainless steel pipe processing technology, specifically to a device for surface passivation treatment of stainless steel BA pipes. Background Technology

[0002] Pickling and passivation can remove various oil stains, rust, scale, weld spots, and other contaminants from the surface of stainless steel pipes. After treatment, the surface becomes a uniform silver-white, which can improve the corrosion resistance of stainless steel. For example, a surface passivation structure for stainless steel BA pipes disclosed in patent announcement number CN221480081U includes a base plate. Support plates are welded to the left and right sides of the top of the base plate. Clamping mechanisms are provided on the sides of the support plates that are close to each other. Through the clamping mechanisms, the output end of the drive motor drives the connected drive gear to rotate, causing the end face gear and three other sets of drive gears to rotate synchronously. This drives the first connecting arm to rotate, and then the second connecting arm to rotate, causing the connecting seats on both sides to move closer together. This, in turn, causes the fixing frames on both sides to move closer together, pressing against both ends of the stainless steel pipe. The first and second clamping plates on both sides extend into the interior of the stainless steel pipe. Then, the output end of the servo motor drives the threaded rod to rotate, causing the first and second clamping plates to move away from each other, clamping the interior of the stainless steel pipe, thus fixing the stainless steel pipe. The clamping method has no dead angle areas, and the pickling coverage is more complete. However, the existing technology CN221480081U describes a surface passivation treatment structure for stainless steel BA pipes, which can only perform surface passivation treatment on individual stainless steel BA pipes, resulting in very low efficiency.
