At present, plastic curved pipes are formed by welding plastic straight pipes into approximate curved pipes, which are abbreviated as miter bends. When large-diameter plastic elbows of miter bends are extruded and formed by an extruder, they cannot well meet the engineering requirements.

It also includes an air sealing plug component, a traction component and an auxiliary shaping component. The air sealing plug component is installed on the traction component. The traction component is arranged on the first cross slide. The air sealing plug component is used to seal the starting end of the plastic elbow extruded by the extruder. After starting the extruder to extrude a section of plastic elbow through the extruder die and the sizing water jacket, the air sealing plug component seals the starting end of the plastic elbow. Then start the extruder again, so that the extruder continues to extrude the plastic elbow through the extruder die and the sizing water jacket. Start the sizing water jacket to cool and shape the plastic elbow. The traction component drives the plastic elbow to carry out bending degree processing according to the production requirements through the air sealing plug component. At the same time, the auxiliary traction component carries out traction shaping on the plastic elbow according to actual needs. When different curvatures of the bent pipe need to be processed, the position of the traction component is adjusted through the first cross slide, so as to adjust the traction line of the plastic elbow by the traction component through the head component. The structure is simple and can produce elbows with large curvature radii and multiple curvature radii, which is simple, convenient and efficient, improves the processing efficiency and reduces the use limitations.
