[0002] The steel pipe grinder is a steel pipe polisher, and the steel pipe grinder is also called a steel pipe rust removal and polishing machine. The steel pipe grinder can remove the rust from round pipes and round sticks. The steel pipe grinder is mainly used for hardware manufacturing, auto parts, hydraulic cylinders, standard parts and rust removal and polishing before and after electroplating. The steel pipe grinder can also remove rust from scrap steel bars and rebars on construction sites. The steel pipe grinder has good rust removal effect and performance for steel bars;

[0003] When the steel pipe grinder removes rust from round pipes and round sticks, the steel pipe is placed between the drum and the roller, and the motor inside the grinder body is started, so that the motor inside the grinder body drives the chain to drive the drum to rotate. At this time, the drum and the roller jointly drive the steel pipe to rotate and move at the same time, and the drive motor is started at the same time, so that the drive motor drives the grinding wheel to rotate through the synchronous belt, so that the grinding wheel grinds the surface of the steel pipe. When the grinding wheel polishes the steel pipe, the grinding wheel grinds off the rust of the steel pipe and produces a lot of dust. The rust dust is easy to float in the gaps of the steel pipe grinder, which makes it more troublesome for the staff to clean the steel pipe grinder. Therefore, we propose an easy-to-clean steel pipe grinder. Utility Model Content
