Abstract

The invention provides a hydraulic mechanical derusting device and process for the inner wall of a special-shaped small-caliber pipe. The hydraulic mechanical derusting device comprise a vibration mechanism, a rotary mechanism and an installation mechanism, wherein the vibration mechanism comprises a base and a top seat; a hydraulic unit is arranged in the middle of the base; the rotary mechanismcomprises a base plate and a rotation disc; the installation mechanism comprises a workbench; a fixing clamp for installing the special-shaped small-caliber pipe is arranged on the workbench; the topseat and the base are fixedly connected through a connecting column; and a rotary seat and the workbench are connected through a fixed column and a telescopic column. According to the hydraulic mechanical derusting device and the process, the frequency of a high-speed reversing solenoid valve is high and can be freely adjusted; and a guide rod can guarantee that the top seat is only displaced onlyin the vertical direction, so that an oil cylinder is protected.

Description

technical field [0001] The invention belongs to the field of rust removal and polishing, and relates to special-shaped small-diameter pipes, in particular to a hydraulic mechanical derusting device and process for the inner wall of special-shaped small-diameter pipes. Background technique [0002] With the development of the industrialization process, the development of technical fields such as construction industry and pipeline transportation is advancing by leaps and bounds. In these application fields, a large number of metal pipes of different shapes are involved and used. [0003] In the follow-up maintenance of metal pipes, rust removal is a relatively important operation. As we all know, the rust removal on the outer surface of metal pipes is relatively simple, but the inside of the metal pipe is usually more complicated because of the thinner pipe diameter and the tortuous internal structure of special-shaped small-diameter pipes. . [0004] At present, we have the ...
