Rotary centrifugal pipe chipless cutting machine

The invention relates to the correlation technical field of pipe cutting equipment, in particular to a rotary centrifugal pipe chipless cutting machine which comprises a cutting rack, wherein a through hole for accommodating a pipe is formed in the cutting rack, and a driven pulley, an opening and closing ring, cutter shanks, a motor drive wheel and a motor are also arranged on the cutting rack. Compared with the conventional cylinder feed type chipless cutting machine, the rotary centrifugal pipe chipless cutting machine has the characteristics of light weight, small size, low cost and quick cutting time. The conventional chipless cutting machine feeds through a cylinder during the high-speed rotation process, but the rotary centrifugal cutting machine instantaneously feeds when a centrifugal block is expanded, so the cutting time is greatly shortened, and the high-speed extrusion production requirements of small pipes are met. Moreover, the cutting machine has the left cutter shank and the right cutter shank, one is provided with a blade, the other one is provided with a pipe pressing wheel, the cut pipe has the advantages of no flanging and attractive cut, does not needed to be cut again, so resource waste which is caused by recutting due to the cut which has burrs and is not attractive are avoided.
