Large elbow opening rounding equipment

Abstract

The invention belongs to the technical field of machining, and particularly relates to large elbow opening rounding equipment. The equipment comprises a rack, a driving part which is mounted on the rack, and a clamping mechanism which is connected with the rotating shaft and used for fixing a to-be-rounded elbow; the output end of the driving part is connected with a rotating shaft; the equipment further comprises rounding mechanisms which are arranged on the two sides of the elbow and used for rounding the two sides of the elbow, a polishing mechanism which is arranged perpendicular to the to-be-rounded elbow, a first magnetic component which is mounted at the bottom of the polishing mechanism, a second magnetic component which is connected in the closed loop, and a flow choking component which is connected in the closed loop and is connected with the polishing mechanism; the second magnetic component and the first magnetic component are oppositely arranged, and the opposite surfaces of the second magnetic component and the first magnetic component have the same magnetism. The elbow is conveniently fixed through arrangement of the clamping mechanism, meanwhile, the elbow is driven by a driving piece to rotate, and the stroke of the elbow is conveniently limited while the elbow rotates through arrangement of the rounding mechanisms.

Description

technical field [0001] The invention belongs to the technical field of mechanical processing, and in particular relates to a device for rounding the mouth of a large elbow. Background technique [0002] Elbows refer to pipe fittings that change the direction of the pipeline in the pipeline system. According to the production process, it can be divided into welding elbow, stamping elbow, push elbow, casting elbow and so on. Elbow materials include cast iron, stainless steel, alloy steel, malleable cast iron, carbon steel, non-ferrous metals and plastics. [0003] After cutting, the large elbow is deformed due to the release of internal stress, which affects the roundness of the elbow, and is prone to deformation or ellipse. At the same time, the surface of the port is raised and burred due to cutting, which affects the next installation. [0004] Most elbows are rounded manually after cutting, and the existing rounding equipment cannot simultaneously round the side of the e...
