Description

Technical Field

[0001] The utility model relates to the technical field of flange production, in particular to a punching device for flange production. Background Art

[0002] The main function of flange punching is to connect accessories on pipelines, such as valves, instruments and other equipment. In some working environments such as high temperature, high pressure, and explosive, the thermal expansion or sudden pressure increase of the fluid medium may cause the pipeline or equipment to burst, seriously endangering personal safety. Therefore, punching several side holes on the flange connection can effectively relieve the pressure inside the pipe and achieve the pressure relief function, thus ensuring safe production. In addition, the holes on the flange can also connect the accessories to the pipeline, facilitating the control and monitoring of the pipeline. The holes on the flange have different processed hole diameters according to their uses and specifications.

[0003] The existing punching device for flange production has low efficiency during the flange punching process. The flange needs to be placed in the equipment for punching work in sequence, with a large labor intensity. Moreover, it is not convenient to clamp and fix according to the size of the flange during the punching process, reducing the scope of use and the working efficiency. Content of the Utility Model
