Problems solved by technology

[0002] In the prior art, the steel is placed outdoors for a long time, and it is easy to grow rust. Therefore, it needs to be derusted every time it is used or before leaving the factory to ensure a smooth surface. , so the grinding efficiency is very low, and different inner diameters will choose different specifications of the grinder, which is very inflexible

Abstract

The invention discloses a rust remover for the inner wall of a hollow steel pipe, which comprises a handle. Controlled by a motor controller, the motor controller is installed on the handle, the motor controller has a built-in lithium battery, which supplies power for the entire drive motor, and is also provided with a button for controlling the switch of the motor, and the motor shaft of the drive motor passes through the machine. The shell protrudes from the outside of the casing, and a rotary box is fixedly installed on the motor shaft of the drive motor. A buffer chamber is arranged inside the rotary box, and a telescopic grinding mechanism is respectively set at both ends of the rotary box. The grinding mechanism is pressed against the inner wall of the steel pipe. The invention can realize the grinding of hollow steel pipes with different inner diameters, quickly removes rust by using grinding balls, has high work efficiency, and solves the problem of low grinding efficiency of the inner wall of the hollow steel pipes.

Description

technical field [0001] The invention relates to a rust remover, in particular to a rust remover for the inner wall of a hollow steel pipe. Background technique [0002] In the prior art, the steel is placed outdoors for a long time, and it is easy to grow rust. Therefore, it needs to be derusted every time it is used or before leaving the factory to ensure a smooth surface. , so the grinding efficiency is very low, and different inner diameters will choose different specifications of the grinder, which is very inflexible. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a rust remover for the inner wall of a hollow steel pipe, which can rapidly polish various hollow steel pipes with different inner diameters, quickly remove rust, and greatly improve work efficiency. [0004] The present invention is achieved through the following technical solutions: a hollow steel pipe inner wall rust remover, including a handle...
