Description

Technical Field

[0001] The utility model relates to the field of composite pipe forming, in particular to a continuous reinforced composite pipe forming device. Background Art

[0002] PE composite pipe is a pipe made of polyethylene and other materials such as steel wire mesh or aluminum plastic. It combines the corrosion resistance of polyethylene with the strength of other materials, so it has better pressure bearing capacity and flow capacity. PE composite pipe is usually used to transport water, gas or other media, especially in environments that require corrosion resistance and high pressure.

The clamping device acts on the steel wire wound on the pipe to improve the stability of the steel wire during winding, ensure the uniformity of the steel wire after winding, and prevent the steel wire from being easily deviated during the winding process.

[0004] In the composite pipe production process of the above patent, when the steel wire is wrapped around the outside of the pipe, the pipe in a solidified state cannot be completely combined with the steel wire, and the steel wire is only in contact with the outer wall of the pipe. The pipe is prone to fall apart and the internal composite structure falls off during use, affecting the service life of the composite pipe. Utility Model Content

[0005] The utility model aims to provide a forming device for a continuous reinforced composite pipe, which realizes the extrusion of materials by limiting the position of a cooling rod. During the extrusion, the cooling rod limits the extruded material to form a pipe shape, and cools the inside of the pipe-shaped material. The cooling can support the extruded material for subsequent transmission. Without cooling the outside of the extruded material, the soft position on the outside can be contacted and fused with the subsequently wound steel wire and coating material, thereby improving the composite effect of the pipe and solving the problems raised in the above-mentioned background technology.

[0011] Preferably, a second heating ring is provided on the outside of the third extruded tube facing the cooling rod, and a wire winding device is provided between the outside of the cooling rod and the outside of the second heating ring.

[0012] Compared with the prior art, the beneficial effects of the utility model are as follows:

[0013] 1. The utility model rotates the transmission ring to extrude the material heated by the first heating ring, so that the softened material moves toward the cooling rod, and is extruded by the cooling rod and the first extrusion tube to form a pipe-shaped material. The inner wall of the pipe will fit the outer wall of the cooling rod. While fitting the outer wall of the cooling rod, the liquid can be pumped by the pump to flow into the flow cavity after transmission, and the flow into the flow cavity can realize the cooling of the inner wall of the extruded pipe. The cooling of the inside of the extruded pipe can complete the support for the subsequent composite processing, so as to avoid the overall softness of the pipe affecting the subsequent composite processing, and the cooling of the inner wall of the pipe will not directly reduce the temperature of the outer wall of the pipe. When the outer wall of the pipe contacts the steel wire wound by the steel wire winding device, the steel wire will be embedded in the softer part of the outer part of the pipe, so that the steel wire is embedded in the outer wall of the pipe, avoiding the need to add adhesive medium later and reducing the processing efficiency of the composite pipe. The embedded steel wire will contact the material extruded at the subsequent shunt pipe position, so that the subsequent extruded material is covered on the outside of the previously wound steel wire through the extrusion of the third extrusion pipe. During the entire pipe composite and manufacturing process, the cooling rod position cools the inner wall of the pipe, and the inside of the cooling pipe serves as a support in the subsequent composite process, thereby improving the stability and efficiency of the pipe composite manufacturing process.

The liquid is transmitted to the flow cavity 15 inside the cooling rod 14 through the second transmission pipe 17. The liquid inside the flow cavity 15 is transmitted to the inside of the third transmission pipe 18 after being squeezed. The liquid inside the third transmission pipe 18 is then The liquid flows back to the water tank 11 for the second time. When the liquid continues to flow inside the cooling rod 14, the inner wall of the extruded pipe material is lowered. The extruded material is wound with steel wire by the steel wire winding device 10 and then transmitted to the third extrusion tube 8. When transmitted to the third extrusion tube 8, it is heated again by the second heating ring 9.
