Description

Technical Field

[0001] The utility model relates to the technical field of pipeline connection, in particular to a pipe flanging device. Background Art

[0002] In plastic pipe systems, due to the characteristics of ultra-high molecular weight pipe materials, it is not easy to connect pipes through hot-melt connection technology, and they can only be connected mechanically.

[0003] After searching, it was found that the publication number is CN214354151U, and the name is a pipe flanging equipment. The application proposed a Chinese utility model patent with authorization announcement number CN209096004U, which discloses a plastic pipe flanging equipment. The equipment structure is quite complicated and the manufacturing cost is high. The pressure plate slides between the upper panel and the lower panel through the cooperation of the connecting column and the through hole, which can adapt to the flanging of pipes of different lengths. However, in actual use, the pressure plate squeezes the other end of the pipe to apply pressure to the pipe, and the pipe is installed in the equipment frame, which means that the longer the pipe is, the larger the overall size of the equipment is. When the pipe is longer, the overall size of the equipment becomes larger and the scope of application is small. Further improvements can be made. At the same time, the application lacks a limit on the flanging of the pipe, and the edge warping problem is prone to occur after the pipe is flanging, which can also be further improved.

[0004] Currently, no effective solution has been proposed for the problems in the related technologies. Utility Model Content
