Description

Technical Field

[0001] This utility model relates to the technical field of pipe fittings for lining pipe repair, and specifically to a steel-reinforced polyethylene composite pipe welding and forming equipment. Background Technology

[0002] Steel-reinforced polyethylene (HDPE) composite pipes are double-sided corrosion-resistant pressure pipes made by continuously extruding low-carbon steel wire as the reinforcing phase and high-density polyethylene (HDPE) as the matrix on a production line. The steel wire mesh is formed by spot welding and plastic extrusion simultaneously. The steel skeleton of the steel-reinforced polyethylene composite pipe is composed of several warp and weft steel wires welded together, while the HDPE is extruded and filled with the steel skeleton. Temperature stability is crucial during the welding process. The welding process causes a rapid temperature rise within the equipment. If the temperature rise is too rapid, the surface smoothness of the composite pipe can easily decrease, and even localized unevenness can occur, severely affecting the aesthetics and performance of the steel-reinforced polyethylene composite pipe. Utility Model Content

[0003] This invention provides a steel-reinforced polyethylene composite pipe welding and forming equipment to solve the problem of unstable temperature leading to decreased surface smoothness during the welding and forming process of steel-reinforced polyethylene composite pipes in the prior art.

[0004] The technical solution adopted by this utility model to solve its technical problem is:

[0005] A steel-reinforced polyethylene composite pipe welding and forming equipment includes a machine base, a rotating cylinder, a power motor, a wire feeding mechanism, a welding mechanism, and a forming mold. The rotating cylinder is rotatably mounted on the machine base and driven by the power motor. The wire feeding mechanism consists of a wire feeding reel and several weft wire feeding reels. The warp wires of the wire feeding reel enter through the warp wire feed reel of the rotating cylinder. A fan is installed near the wire feeding reel, and the fan outlet is connected to an internal ventilation pipe that extends into the interior of the rotating cylinder. The weft wire feeding reels are fixed around the rotating cylinder on all four sides. The warp and weft wires simultaneously enter the winding reel of the welding mechanism. Electrode welding wheels corresponding to the weft wire feeding reels are installed on the winding reel. The winding reel is connected to the forming mold. A water cooling sleeve with a hollow annular structure is installed on the outlet pipe of the winding reel.

[0006] The aforementioned wire feed reel is fixedly installed on the frame.

[0007] When the steel-reinforced polyethylene composite pipe welding and forming equipment of this utility model is working, the fan is started, and the fan continuously sends cold air into the rotating cylinder through the internal ventilation pipe. The cold air carries away the heat generated during the welding and extrusion forming process. At the same time, the steel-reinforced high-density polyethylene plastic mother pipe formed by the winding reel outlet pipe has a high temperature and low hardness. If it directly enters the forming mold, the surface of the final pipe will be uneven, damaging the smoothness of the pipe. The steel-reinforced high-density polyethylene plastic mother pipe formed by the winding reel outlet is first cooled by water through the water cooling sleeve. After the temperature drops initially, the hardness of the mother pipe increases, and then it is sent into the forming mold to obtain the finished product, which can effectively ensure the surface smoothness of the steel-reinforced polyethylene composite pipe.

[0008] This invention, by incorporating an internal ventilation and cooling mechanism and a water cooling sleeve into existing composite pipe welding and forming equipment, can promptly remove the heat generated during welding and forming, while simultaneously performing surface heat exchange and cooling on the pipe body formed by injection molding. This ensures the surface hardness of the pipe body, guarantees the molding quality, and ensures the smoothness and aesthetics of the pipe body surface. Attached Figure Description

A fan 11 is installed near the wire feeding reel 4. The air outlet of the fan 11 is connected to the inner ventilation pipe 12, which extends into the interior of the rotating cylinder 2. The weft wire feeding reel 7 is fixed around the top, bottom, left and right sides of the rotating cylinder 2. The warp wire 14 and the weft wire 15 simultaneously enter the winding reel 8 of the welding mechanism.

The cold air carries away the heat generated during the welding and extrusion forming process. At the same time, the steel-reinforced high-density polyethylene plastic mother pipe formed by the winding reel outlet pipe has a high temperature and low hardness. If it directly enters the forming mold, the surface of the final pipe will be uneven, damaging the smoothness of the pipe. The steel-reinforced high-density polyethylene plastic mother pipe formed by the winding reel outlet is first cooled by water through the water cooling sleeve. After the temperature drops initially, the hardness of the mother pipe increases, and then it is sent into the forming mold to obtain the finished product, which can effectively ensure the surface smoothness of the steel-reinforced polyethylene composite pipe.
