Description

Technical Field

[0001] The utility model relates to the technical field of aluminum tube processing, in particular to a tool for removing burrs inside and outside the aluminum tube. Background Art

[0002] During the production process of aluminum tubes, sometimes there will be cut aluminum tubes. In order to improve the quality of subsequent use, it is necessary to rotate the aluminum tubes inside and outside to remove the burrs remaining on the broken part. Therefore, an aluminum tube inside and outside deburring tool is used.

[0003] Currently, tools for deburring aluminum tubes generally include a cutter disc, a face turning and deburring tool, and a chamfering tool mounted on the cutter disc. The face turning and deburring tool and the chamfering tool are removably fixed to the cutter disc via mounting slots on the end face of the cutter disc, with the mounting slots being radially arranged along the cutter disc. The face turning and deburring tool comprises a base and a blade assembly, which includes a fixed block and a blade removably fixed to the fixed block. The blade and the fixed block are each provided with a screw hole, and the fixed block is fixedly connected to the base. The blade is mounted on the fixed block via screws, and the blade and the mounting slot are arranged at an angle of 40 to 45 degrees. This arrangement allows the axle tube to be chamfered while the end face of the axle tube is turned and deburred, greatly improving processing efficiency and preventing chips from flowing into the interior of the axle tube. The face turning and deburring tool can move along the mounting slot to change the cutting point of the blade.

[0004] However, during use, the existing aluminum tube deburring tool has a cutter head length that cannot be adjusted, and tools of different specifications cannot be installed, resulting in the inability to perform deburring processing on aluminum tubes of different lengths.
