Beveling machine for cutting pipeline

Abstract

The invention discloses a beveling machine for cutting a pipeline. The beveling machine comprises a left movable ring, a right movable ring, a left gear ring, a right gear ring, a left fixed ring and a right fixed ring, wherein the left movable ring and the right movable ring are respectively and fixedly arranged on the left gear ring and the right gear ring; the left fixed ring and the right fixed ring are respectively and fixedly provided with a plurality of eccentric shafts along the circumferential direction; each eccentric shaft comprises a shaft body and a cylindrical bulge part arranged at one end of the shaft body, and a roller bearing is arranged on each cylindrical bulge part; the multiple roller bearings are movably embedded into grooves at the inner side surfaces of the left and right gear rings; one end of the left fixed ring and one end of the right fixed ring are respectively provided with a left connecting block and a right connecting block; the left connecting block and the right connecting block are movably connected by virtue of a connecting shaft; one end, which is away from the left connecting block, of the left movable ring and one end, which is away from the right connecting block, of the right movable ring are contacted with butting surfaces of the left fixed ring and the right fixed ring; the other ends of the left and right movable rings are contacted with the other butting surfaces of the left and right fixed rings. The beveling machine has favorable axiality, is high in stability during cutting operation, can rotate stably and smoothly, is high in cutting precision and can be used for conveniently positioning left and right parts.

Description

technical field [0001] The invention relates to a beveling machine, in particular to a beveling machine used for pipe cutting in chemical industry, natural gas, nuclear power, petroleum and other industries. Background technique [0002] In the pipeline installation projects of various industries, the quality of the pipeline is particularly important. The quality assurance of the pipeline installation is mainly the cutting and welding of the pipeline. The cutting is the former. In order to improve the quality of the road, cutting and beveling machines are currently used for cutting pipes, especially thick-walled and large-diameter pipes. On the one hand, the efficiency of the existing equipment is extremely low, and the quality of the nozzle after processing cannot be guaranteed, and the material change of the nozzle caused by high temperature will directly affect the next welding work; Higher and higher, cold cutting of metal pipes has been generally proposed as a pipe cut...
