Description

Technical Field

[0001] The invention relates to the technical field of stainless steel pipe polishing, in particular to a multi-station stainless steel pipe polishing device. Background Art

[0002] Stainless steel pipe is an important industrial material with a wide range of applications. It is a hollow long round steel made of stainless steel, mainly used in industrial pipelines such as petroleum, chemical, medical, food, light industry, mechanical instruments, and mechanical structural components. Due to its excellent torsional strength and light weight, stainless steel pipe is also often used to manufacture mechanical parts and engineering structures.

[0003] However, during the manufacturing process of stainless steel pipes, due to differences in raw materials or production processes, slight bumps and depressions may appear on the surface. These bumps and depressions will cause the surface of the stainless steel pipe to become rough and uneven, resulting in increased friction during use, thereby affecting the service life of the product, and making the surface of the stainless steel pipe susceptible to oxidation, rust or corrosion, and the stainless steel pipe needs to be polished.

[0004] Existing polishing machines generally use manual loading, which requires workers to operate manually, have slow transportation speeds, and are prone to misalignment and blockages, which affect the overall efficiency of the polishing process. In addition, polishing machines cannot adapt well to steel pipes of different thicknesses. Whenever steel pipes of different sizes are replaced, the machine needs to be adjusted or the adapter device replaced, which will increase the operation time and affect the overall production efficiency.

[0005] Therefore, we propose a multi-station stainless steel pipe polishing device to solve the above problems. Summary of the invention
