Description

Deburring device for steel pipe cutting port

Technical Field

The invention relates to the technical field of pipeline machining, in particular to a deburring device for a steel pipe cutting port.

Background

When the pipe fitting is operated, the pipe fitting is usually cut off by using a pipe cutting tool, and then the cut end face of the pipe fitting and the inner and outer walls of the section need to be subjected to deburring by using a tool so as to avoid scratching personnel and influencing the installation effect. Most structures of the existing steel pipe burr grinding devices are complex, operation is complex, the size is large, the steel pipe burr grinding devices are inconvenient to carry, flexibility is poor, when the steel pipe burr grinding devices are operated outdoors, the grinding devices are inconvenient to carry, deburring can only be carried out manually, manual deburring is possible, and the deburring depth is different, and the effect is poor. On the other hand, the existing deburring device can not polish the inner ring burrs and the outer ring burrs of the pipe fitting port through the same tool, so that two specific tools are needed to finish polishing the inner ring burrs and the outer ring burrs of the steel pipe port respectively, the more tools are used, the more portability is reduced, and the working efficiency and the working quality are further reduced.

Among the prior art, utility model patent with publication number CN211072934U discloses a steel pipe port burr trimming device, including the barrel, barrel bottom central authorities department is fixed with the handle. The advantages are that: the workman can be through the light portable device of taking of handle to carry out the work of polishing to the steel pipe burr to through the setting of conical barrel and toper piece, the conical barrel can effectually be to steel pipe port outer lane burr, and the toper piece can effectually be to steel pipe port inner circle burr, and then effectually reached through a portable device alright polish the purpose of pipe port inner circle and outer lane burr. And because the frosting face of toper bucket and toper piece all outwards expands with center department, so toper bucket and toper piece can carry out the work of polishing to the steel pipe of multiple different diameters, the effectual practicality that has improved the device through the setting of two protection casings, can effectually prevent that the staff from touching high-speed pivoted toper bucket and toper piece, and then improved the device's security performance. But its shortcoming lies in, lack steel pipe fixed establishment, whether make and to polish can only press the steel pipe with the naked eye with the visual cone piece coaxial with the steel pipe, this leads to polishing and can appear the deviation, reduce the effect of polishing, can only push down the steel pipe with artifical hand-held device simultaneously and polish, long-time pressing needs a large amount of physical power, and the degree of depth of polishing at every turn can't accomplish unanimously, further reduce the effect of polishing, one point lies in when the steel pipe of a model is polished often in addition, the cone piece can only be changed after the position wearing and tearing that correspond to the model pipe diameter are serious, and other positions of this moment cone piece have not been used yet, cause the wasting of resources.
