Description

Technical Field

[0001] The utility model relates to the technical field of corrugated pipes, in particular to a device for cutting and polishing the end face of a corrugated pipe. Background Art

[0002] Bellows mainly include metal bellows, corrugated expansion joints, corrugated heat exchange tubes, diaphragm boxes and metal hoses. Metal bellows are mainly used to compensate for pipeline thermal deformation, reduce shock, absorb pipeline settlement deformation, etc. They are widely used in petrochemical, instrumentation, aerospace, chemical, electric power, water conservancy, metallurgy and other industries. Corrugated tubes made of other materials such as plastics play an irreplaceable role in media transportation, power threading, machine tools, home appliances and other fields.

[0003] A Chinese patent with the announcement number CN219853907U discloses a polishing device for processing bellows, including an operating table, a threaded block is arranged above the operating table, a wire brush is fixedly connected to the bottom of the threaded block, a hanger is fixedly connected to the upper surface of the operating table, the hanger is in a U-shaped structure, and a hydraulic rod is fixedly connected to the lower surface of the top of the hanger. In the polishing device for processing bellows, the bellows is fixed between the second fixed disk and the first fixed disk, and the telescopic end of the hydraulic rod extends to drive the threaded block to descend and fit into the thread groove of the bellows. The rotation of the motor drives the gear to rotate, and then drives the first fixed disk to rotate through the gear block. At the same time, with the movement of the slide plate, the wire brush at the bottom of the threaded block grinds and polishes the bellows. A threaded block that matches the external thread structure of the bellows is provided, so that the thread gap of the bellows can be polished, making the polishing of the bellows more uniform and thorough.

[0004] As mentioned above, the patent provides a polishing device for processing bellows. Although it can grind the thread gap of the bellows to make the polishing of the bellows more uniform and thorough, when the bellows is processed, the bellows needs to be cut and the end face needs to be polished. However, it is difficult to ensure uniform grinding of the end face by grinding in the horizontal direction, and the adaptability of grinding needs to be improved. Utility Model Content
