Description

Technical Field

[0001] The utility model relates to a small round tube polishing machine with stable custody, belonging to the technical field of round tube polishing machines. Background Art

[0002] Polishing is an indispensable process in the production and processing of pipes. It can reduce the surface roughness of the pipes and obtain a bright and smooth surface.

[0003] The prior art "Application No.: 2021227486678" discloses a sand belt type pipe polishing device, which has the following defects: 1. When the diameter of the pipe is relatively large, the pipe supporting rubber wheel can only support a small part of the bottom of the pipe, the pipe is easy to slip out, and the tube is unstable; when the diameter of the pipe is relatively small, the top of the pipe supporting rubber wheel will be higher than the top of the pipe, and the sand belt will first contact the top of the pipe supporting rubber wheel during polishing, thereby affecting the polishing of the pipe; 2. There are only support wheels and upper pressure wheels. When the diameter of the pipe is small, if the polishing wheel is lowered relatively low, it is easy to contact the pipe supporting rubber wheel and cause wear to it. If the polishing wheel is not lowered low enough, it cannot contact the small round tube for polishing.

[0004] Therefore, how to provide a small round tube polishing machine with stable hosting is the research purpose of the utility model. Utility Model Content

[0010] Furthermore, the rear end of the polishing wheel is connected to a first buffer cylinder, and the rear end of the tube pressing rubber wheel is connected to a second buffer cylinder.

[0011] The beneficial effects of the utility model are: 1. The two groups of tube-mounted rubber wheels are arranged as an inclined and movable figure-eight opening and closing structure.
