Abstract

The present invention relates to a brushing device for simultaneously processing the inner and outer diameters of a pipe and a pipe processed by the same. More specifically, the invention relates to a brushing device for simultaneously processing the inner and outer diameters of a pipe and a pipe processed by the same, which can simultaneously process the inner and outer diameters of a pipe by supporting a hollow pipe with an idler roller and simultaneously performing rolling and transfer in a single process. A brushing device for simultaneous processing of the inner and outer diameters of a pipe according to one embodiment of the present invention relates to a device for simultaneously brushing the inner and outer circumferences of a pipe, comprising a main frame; a main bed installed on the main frame and supporting the pipe with a pair of idle rollers; a rotational transfer unit that descends from the upper side of the main bed and moves in conjunction with the idle rollers, and rotates and advances the pipe using a plurality of rotational rollers arranged in a row; a first movable unit that slides along the longitudinal direction of the main frame and is inserted into the inner circumference of the pipe to operate a first brush; and a second movable unit installed on the side of the main frame and approaching perpendicularly to the longitudinal direction of the pipe to operate a second brush.

Description

Brushing device for simultaneous processing of inner and outer diameters of pipes and pipe processed by the same The present invention relates to a brushing device for simultaneously processing the inner and outer diameters of a pipe and a pipe processed by the same. More specifically, the invention relates to a brushing device for simultaneously processing the inner and outer diameters of a pipe and a pipe processed by the same, which can simultaneously process the inner and outer diameters of a pipe by supporting a hollow pipe with an idler roller and simultaneously performing rolling and transfer in a single process. The following description provides background information regarding the present embodiment and does not describe prior art. Currently, at the production site, pipe cutting and processing cannot be carried out in a single process, so the process is subdivided more than necessary. In other words, after cutting the pipe and machining the pipe hole, a subsequent process is essential due to the burr generated at the fixed point during cutting and machining. In addition, when machining pipe holes, the machining process proceeds in the order of basic hole machining, roughing, and finishing using the bottom edge of an end mill without center drilling or drilling processes, so the machining time per hole is about 10 minutes, and as a result, the fixed cost of the equipment and the time loss rate are high. In addition, improvements to the pipe deburring process and pipe extraction are necessary. In other words, uniform quality is not ensured through the deburring process, and there is a risk of operational safety issues arising from the scattering of deburring chips. In addition, there are concerns about musculoskeletal disorders among workers caused by heavy lifting and safety accidents resulting from prolonged work.
