Description

Device for Eliminating Tube Burr

The present invention relates to a tube deburring device for removing burrs from a tube end while preventing the removal residue from flowing into the tube.

In general, tubes are used to transfer gases or fluids, and are formed of various diameters and materials.

Among these, the most commonly used tubes are metal tubes, which can be used to transfer gases or fluids between the apparatus and the apparatus.

When the metal tube 10 is cut as shown in FIG. 1, a burr 12 may be formed on the cut surface.

This burr 12 must be removed before the burr 12 is removed as the burr gauges 20 shown in Fig. 2 to remove the burr 12.

Conventional burr gauges 20 are made such that a portion is inserted into the cut end of the metal tube 10 and the operator manually presses and rotates to grind the burr 12.

However, such a conventional burr gauges 20 require a user to apply pressure with the force of a handmade person, which is difficult to remove the burr 12 and takes a long time.

In addition, when the burr gait tool 20 grinds the burr 12, the burr 12 foreign substances are introduced into the tube, which may cause problems later, 12) is required to be removed.
