Description

Technical Field

[0001] This utility model relates to the field of PE pipe processing technology, specifically to a fire-resistant PE pipe bending processing device. Background Technology

[0002] Fire-resistant PE pipes are a replacement product for polyolefin pipes and fittings with ideal temperature resistance and aging resistance. They have the advantages of cross-linked polyethylene pipes, such as high temperature resistance and no scaling, while making up for the disadvantages of cross-linked pipes, such as the inability to be heat-fused and the inability to recycle waste and substandard products.

[0003] A utility model with publication number CN211763450U discloses a pipe bending device for processing PE pipes. The device includes a base plate, on which two fixing plates are fixedly connected to the right side of the upper surface. A first bearing shaft is snapped onto the upper surface of each of the two fixing plates facing each other. This pipe bending device for PE pipes utilizes a motor. The output shaft of the motor rotates, driving a half-gear to rotate. The half-gear, through a gear, drives a first rotating shaft and a first U-shaped plate to rotate. The first U-shaped plate can then drive an extrusion roller to bend the PE pipe.

[0004] Through the above technical solution, the inventors discovered at least the following problems: the extrusion rollers continuously extrude and bend the PE pipe, making it inconvenient to remove them from the equipment when maintenance, repair, or replacement is required. Therefore, we propose a fire-resistant PE pipe bending device. Utility Model Content
