Description

Technical Field

[0001] The utility model relates to the technical field of metal processing and grinding, in particular to a metal surface grinding machine. Background Art

[0002] Grinding is a type of surface modification technology, which generally refers to a processing method that uses rough objects to change the physical properties of the material surface through friction. The main purpose is to obtain a specific surface roughness.

[0003] There is an existing patent (publication number CN219747425U) and a round tube abrasive belt grinder. The abrasive belt in this patent is loosely set. After the metal round tube is clamped by the clamp, the metal round tube is pressed on the upper part of the abrasive belt, so that the metal round tube makes the abrasive belt tight. The tightness of the metal round tube and the abrasive belt can be adjusted by adjusting the upper and lower positions of the clamp 22. The abrasive belt has a greater fit with the surface of the metal round tube, which can increase the grinding speed. Once the tightness of the metal round tube and the grinding belt is adjusted, the drive motor three is started. The drive motor three rotates through the meshing rotation of gear one and gear two to drive the roller to rotate. The rotation of the drive motor one drives the metal round tube, thus completing the partial grinding of the metal round tube. The above patent can only grind one round tube at a time, and the round tube needs to be clamped each time it is ground, which leads to a decrease in efficiency. In production, after the round tube is cut, the outer wall needs to be polished in batches, or the stacked round tubes need to be polished and rusted when they need to be processed. At the same time, it is very difficult to replace different numbers of sand belts or replace the sand belts in the above patent, and it is not convenient to use for round tubes of different diameters and lengths.

[0004] Therefore, we propose a metal surface grinding machine, which is conducive to the simultaneous outer wall grinding of multiple round tubes, the batch rust removal of the outer walls of round tubes, the disassembly and replacement of the grinding area, and the forward grinding of longer round tubes. It is suitable for round tubes of different sizes and lengths. Utility Model Content
