Description

Technical Field

[0001] The utility model relates to the technical field of PE pipe processing, in particular to a forming extrusion device used for PE pipe production. Background Art

[0002] PE is the abbreviation of polyethylene, which is a high-molecular inorganic compound with a very complex structure. It is polymerized from ethylene. Due to its different densities, people divide PE into three types of polyethylene: high, medium and low. The higher the density of polyethylene, the stronger its rigidity and mechanical strength. It can only be polymerized under high pressure. In industrial consumption, ordinary container and pipeline manufacturing materials and many electrical insulation materials such as radar and television use high-density polyethylene materials. As the density of polyethylene decreases, its hardness becomes smaller and smaller. When the density is very low, polyethylene becomes very soft and can only be polymerized under high pressure. Therefore, PE, a high-molecular polymer material, is widely used worldwide.

[0003] There is a PE water supply pipe extrusion molding device CN217293405U, which includes a hopper, which is connected to a conveying device, and the conveying device is provided with a connecting flange at the connecting end to connect with a molding pipe, and the molding pipe is provided with a shaping device at the outlet. The PE water supply pipe extrusion molding device is provided with a shaping device at the end of the molding pipe, and a plurality of shaping plates are provided on the shaping device. The connecting spring is located between the connecting seat and the shaping plate, so that the shaping plate can play a buffering role and play a re-shaping role on the outer wall of the PE water supply pipe. The adjusting cylinder can adjust the position of the shaping plate according to the extrusion molding requirements of the PE water supply pipe, and control the shaping force between the shaping plate and the outer wall of the PE water supply pipe. At the same time, a heating device is provided in the PE water supply pipe, and the heating device can soften the material again to improve the processing and molding quality of the PE water supply pipe.

[0004] However, when the existing device is used, after the PE water pipe is extruded from the shaping plate, the pipe is still in a relatively hot state, and there is no structure to restrict the pipe, so the extruded water pipe may tilt or break. To solve the above problems, a forming extrusion device for PE pipe production is proposed. Utility Model Content

[0006] Furthermore, a support seat is fixedly arranged on the support frame, the support seat is flush with the shaping plate, the support seat is semi-cylindrical, a cooling plate is arranged on the arc-shaped bottom surface of the support seat, a cooling channel is arranged inside the cooling plate, the cooling channel of the cooling plate is respectively connected to the liquid inlet and the liquid outlet, and the liquid inlet and the liquid outlet are connected to the external circulating cooling water tank;

[0007] Furthermore, the central column is fixedly arranged on the shaping plate, the central column is suspended above the supporting seat and is parallel to the supporting seat, and a plurality of limiting structures are arranged on the central column;

[0008] The limiting structure includes an electric push rod and a limiting plate. One end of the electric push rod is fixedly connected to the center column, and the other end is fixedly connected to the limiting plate. The electric push rod is connected to an external controller. There are three electric push rods, which are evenly distributed on the center column. There are three limiting plates, which correspond to the three electric push rods one by one.

[0009] Beneficial effects of the utility model:
