The specific embodiment:
Therefore the following stated, only for embodying the preferred embodiment of the principle of the invention, does not limit protection scope of the present invention
as Fig. 1 to 5, be depicted as the embodiment of double-side chamfering machine inside and outside a kind of bend pipe of the present invention, it comprises frame 1, on described frame 1, tube bending jig 3 is installed, chamfering head 2 is installed on frame 1, the structure of described chamfering head 2 comprises a motor 21, the main shaft of described motor 21 is connected with rotating shaft 22, the front end of described rotating shaft 22 is equipped with interior chamfering tool 23 and outer chamfering tool 24 prejudicially, smear metal cutting edge and the rotary main shaft of described interior chamfering tool 23 and outer chamfering tool 24 have angle, be positioned on the frame 1 in rotating shaft 22 the place aheads the hold-down mechanism 4 that the bend pipe end is compressed is installed, in the present embodiment, interior chamfering blade 23 and outer chamfering blade 24 are positioned at homonymy, and the eccentric throw of interior chamfering blade 23 equates with the interior pore radius of bend pipe a, the eccentric throw of outer chamfering blade 24 equates with the exterior radius of bend pipe a.
