[0002] Metal pipe chamfering is a process of cutting the end or edge of a metal pipe to form a bevel at a specific angle.

[0003] After metal tubes are chamfered, due to the influence of the metal's plastic deformation characteristics, the tool squeezes the edge of the tube during chamfering, causing material tearing or accumulation.

An end cover 612 is fixed to the rear end of the outer wall cleaning block 606, and a second spring 609 is fixed between the end cover 612 and the end face cleaning block 608.

[0042] The cooperation of the second spring 609 enables the end face cleaning block 608 to contact the end face of the metal pipe, so that the end face of the metal pipe can be cleaned and deburred.

[0043] The chamfering tool assembly 7 includes a second transmission block 701, a chamfering tool 702 and a limiting bolt 703. The second transmission block 701 is movably inserted into the vertical slot of the cross slot 4. The chamfering tool 702 is assembled to the end of the second transmission block 701 through the limiting bolt 703 and the limiting nut.

[0049] When adjusting the position of the cleaning assembly 6 and the chamfering tool assembly 7, the driving motor 501 is started, and the rotating disk 502 is driven to rotate by the output shaft of the driving motor 501. When the rotating disk 502 rotates, the radial position of the cleaning assembly 6 and the chamfering tool assembly 7 will be changed through the action of the guide groove 503 and the transmission column 504. At this time, the cross groove 4 plays a guiding role, allowing the cleaning assembly 6 and the chamfering tool assembly 7 to move inward or outward at the same time, realizing the synchronous movement of the cleaning assembly 6 and the chamfering tool assembly 7, which can effectively align the end of the metal pipe and is suitable for metal pipes of different diameters.
