Description

Technical Field

[0001] The invention relates to a steel pipe processing device, in particular to a portable large-scale steel pipe end surface flattening device. Background Art

[0002] After the steel pipe is cut, burrs will appear on the cut surface. These burrs will not only affect the subsequent use of the steel pipe, but may also cause scratches on the steel pipe after it falls, affecting its quality. Therefore, it is necessary to use a steel pipe end surface leveling device to deburr and level the burr surface of the steel pipe.

[0003] The existing leveling device is only an ordinary cutting machine, which cuts the end face of the steel pipe by a blade. During use, the staff needs to use a special fixing tool to fix the steel pipe, and then use the cutting machine to level it.

[0004] However, due to the inconsistent specifications of steel pipes, fixing tools of different specifications are needed. However, the existing fixing tools have a simple structure and fixed specifications, and cannot fit the sizes of steel pipes of different specifications, thus affecting their fixing effect. Poor fixing effect will cause the steel pipe to shift during the leveling process, which not only affects the leveling effect, but also seriously damages the steel pipe, resulting in a waste of resources.

[0005] Therefore, the existing leveling device has the problem that the fixing tooling used has poor fixing effect, affects the leveling effect, and causes waste of resources. Summary of the invention
