Technical Field

[0001] The utility model belongs to the field of steel bar processing, and in particular relates to a steel bar deburring device. Background Art

[0002] During the construction process, steel bars are needed to make steel cages. However, most of the purchased steel bars are of inappropriate length and need to be cut. After the steel bars are cut, burrs will inevitably remain at the cut, which will affect the normal use of the steel bars. Therefore, the burrs at the ends of the steel bars need to be removed.

[0003] At present, the common practice is to use an angle grinder for manual removal. Due to the long length of the steel bar, when using the angle grinder to remove the burrs on the end of the steel bar, it is necessary to move the angle grinder or move the steel bar so as to deburr the entire annular cut edge of the steel bar. Since the grinding angle needs to be constantly changed, the workload is large.

[0004] Therefore, we propose a steel bar deburring device to solve the above problems. Utility Model Content
