Abstract
Description
Technical Field
[0001] This utility model belongs to the field of steel pipe polishing technology, and in particular relates to an automatic polishing machine for high-gloss stainless steel seamless pipes. Background Technology
[0002] Stainless steel pipe is a hollow, long, round steel material. When the bending and torsional strength are the same, stainless steel pipe is lighter in weight, so it is also widely used in the manufacture of mechanical parts and engineering structures. In actual production or daily life, some stainless steel pipes may rust due to storage conditions, requiring subsequent polishing of the rusted surface. Other steel pipes have higher usage requirements, and their surface roughness may not meet the specifications, necessitating polishing. After polishing, the surface needs cleaning. Currently, a rotary brush is commonly used to remove metal residue from the stainless steel pipe surface. However, metal debris remaining on the surface is difficult to remove due to static electricity or other factors. This has led to the development of devices that use liquid for cleaning, such as the automatic stainless steel pipe surface polishing machine described in Chinese utility model patent document CN213616002U. This cleaning device uses liquid to rinse the internal steel pipe and then dries it. This method has a complex structure, and if the drying mechanism does not effectively remove liquid residue, the steel pipe may still corrode and rust. Therefore, it not only has a complex structure but also carries the risk of the steel pipe rusting again.
[0003] Therefore, it is essential to invent an automatic polishing machine for high-gloss stainless steel seamless pipes. Utility Model Content

The inner side of the conveying frame is equipped with conveying rollers that rotate up and down. There are two conveying rollers, one of which rotates through the conveying frame and is fixedly connected to the output end of the conveying motor.
[0009] Preferably, an airflow generating fan is fixedly installed inside the airflow injection pipe. The airflow injection pipe is installed at an angle above the inverted flow shroud. One end of the airflow injection pipe is located at the tangent point above the inverted flow shroud, and one end of the suction pipe is also located at the tangent point above the inverted flow shroud. The suction pipe and the airflow injection pipe are fixedly installed above the inverted flow shroud in an alternating manner.
[0010] Preferably, the airflow guide fixedly installed inside the backflow shroud is a spiral blade, which is used to guide the airflow.
[0011] Compared with the prior art, the present invention has the following beneficial effects:
[0012] This utility model of steel pipe residue processor does not use liquid cleaning to remove metal residue from the surface of steel pipes. Instead, it uses airflow to clean the surface. This method eliminates the need for a subsequent drying mechanism. Furthermore, because the cleaning medium is air, the steel pipe surface will not be subject to further corrosion due to residual cleaning medium. The overall structure is simple and can maximize the protection of the steel pipe from subsequent corrosion by liquid media, reducing the chance of rust recurring after polishing.

[0024] The steel pipe scraping cover 4 includes a scraping outer cover 41, a flow-blocking cleaning brush 42, and an internally threaded sleeve 43.

[0025] Example 1:
[0026] Specifically, the steel pipe polishing machine 2 includes a mounting base 21, a polishing motor 22, a blocking cover 23, and a polishing disc 24. The mounting base 21 is fixedly mounted on the polishing worktable 1. Two parallel polishing motors 22 are fixedly mounted on the upper ends of the mounting base 21. An arc-shaped groove is provided below the polishing motors 22, and the arc-shaped groove is located in the middle of the mounting base 21. A blocking cover 23 is fixedly mounted on the polishing motors 22. A polishing disc 24 is provided inside the blocking cover 23. The output end of the polishing motor 22 rotates through the blocking cover 23 and is fixedly connected to the polishing disc 24. The two polishing discs 24 rotate in opposite directions and polish the surface of the steel pipe.
[0027] Specifically, the steel pipe conveyor frame 5 includes a conveyor frame 51, conveyor rollers 52 and a conveyor motor 53. The conveyor frame 51 is fixedly installed on the polishing worktable 1. The conveyor rollers 52 are installed on the inner side of the conveyor frame 51 and rotate up and down. There are two conveyor rollers 52. One end of one of the conveyor rollers 52 rotates through the conveyor frame 51 and is fixedly connected to the output end of the conveyor motor 53.
[0028] Specifically, an airflow generating fan is fixedly installed inside the airflow injection pipe 35. The airflow injection pipe 35 is installed at an angle above the inverted flow shroud 32. One end of the airflow injection pipe 35 is located at the tangent point above the inverted flow shroud 32.

[0029] Specifically, the airflow guide 36 fixedly installed inside the backflow cover 32 is a spiral blade, and the airflow guide 36 is used to guide the airflow.
[0030] Example 2:
[0031] When polishing is required for the steel pipe, turn on the device and place one end of the steel pipe between the two conveying rollers 52 of the steel pipe conveying frame 5. The conveying motor 53 drives one of the conveying rollers 52 to rotate, and the rotating conveying roller 52 drives the steel pipe to be conveyed. When the steel pipe comes into contact with the polishing disc 24 of the steel pipe polishing machine 2, the polishing disc 24 polishes it. During this process, the baffle 23 outside the polishing disc 24 will block the splashing metal debris. Then the steel pipe enters the backflow hood 32 of the steel pipe residue processor 3. At this time, the airflow generated by the fan inside the airflow injection pipe 35 enters the backflow hood 32. The airflow flows along the inner wall of the backflow hood 32 and moves in a spiral pattern. The airflow flows in a spiral pattern. During this process, the airflow guide 36 further guides the airflow, and the spiral airflow treats the metal residue on the surface of the steel pipe. The spiral airflow carries the metal debris residue and then enters the suction pipe 34. The suction pipe 34 then discharges the airflow carrying the metal debris residue into the metal debris collection box. Secondly, some airflow may continue to flow forward, but it will be blocked by the flow-blocking cleaning brush 42 of the steel pipe scraper cover 4 to prevent the airflow carrying the metal debris residue from being discharged outside. Subsequently, the flow-blocking cleaning brush 42 of the steel pipe scraper cover 4 will scrape and clean the surface of the steel pipe, further reducing the metal debris residue attached to the surface of the steel pipe.
