[0011] This utility model describes a device for fabricating solid high-sided polyethylene steel wire composite reinforcement on the outer wall of a pipe, such as... Figures 1-4 As shown, the system includes a solid composite rib manufacturing mechanism and a solid composite rib bending and bonding mechanism. The solid composite rib manufacturing mechanism consists of an extruder 1, a molding machine 2, an air-cooled mold, and a water-cooled mold. The extruder 1 extrudes a reinforcing rib preform with steel wire from the molding machine 2, which then sequentially enters the air-cooled mold and the water-cooled mold for cooling and shaping. The solid composite rib bending and bonding mechanism consists of a hot air gun 12 and a composite rib bending and extrusion device 13. The hot air gun 12 heats and melts the bottom surface of the solid composite rib and the outer surface of the formed pipe. The composite rib bending and extrusion device 13 bends the solid composite rib according to the shape of the pipe and spirally winds and welds it to the outer circumference of the pipe.

[0012] The bottom of the air-cooling mold and the water-cooling mold is provided with a forming bottom plate 3, and two groups of air-cooling forming boxes 4 are arranged side by side on the forming bottom plate 3. First air-cooling pipes 6 are connected to the air-cooling forming boxes 4 and communicate with the inner cavities. The air-cooling forming boxes 4 are provided with first air vents 5 on the opposite inner sides. The air-cooling pipes 6 are connected to the air-cooling forming boxes 4 and communicate with the inner cavities. The air with lower temperature in the air-cooling pipes 6 can be blown out to the air-cooling mold through the first air vents 5 and act on the two side surfaces of the internal composite rib to realize heat exchange and cooling. The second air-cooling pipes 7 are installed on the top between the air-cooling forming boxes 4. The second air-cooling pipes 7 are provided with second air vents 8 on the bottom. The air with lower temperature in the second air-cooling pipes 7 can be blown out to the top of the air-cooling mold through the second air vents 8 to realize omnidirectional air-cooling and cooling of the air-cooling mold. The forming bottom plate 3, the second air-cooling pipes 7 and the air-cooling forming boxes 4 on the two sides form a relatively closed air-cooling mold. The air-cooling forming boxes 4 serve as side molds for forming the composite rib. The air-cooling mold serves as a forming channel for the blank to move. Under the heat exchange effect of the cold air, the composite rib blank is slowly cooled and solidified.

[0013] The forming bottom plate 3 is further provided with two groups of water-cooling forming boxes 9 arranged side by side. The water-cooling forming boxes 9 are connected to water injection pipes 10 which communicate with the inner cavities. The water-cooling top pipes 11 are installed on the top between the water-cooling forming boxes 9. The water-cooling top pipes 11 and the water-cooling forming boxes 9 can be injected with cooling water to form heat exchange with the internal composite rib. Compared with air-cooling, the heat exchange of water-cooling is more rapid to rapidly cool and solidify the internal composite rib. The forming bottom plate 3, the water-cooling top pipes 11 and the water-cooling forming boxes 9 on the two sides form a relatively closed water-cooling mold to provide a heat exchange forming channel for the composite rib.

[0014] The composite rib bending and extruding device 13 comprises an arc-shaped cooling mold 19 which can press the solid composite rib against the outer periphery of the pipe. The solid composite rib extruded by the air-cooling mold and the water-cooling mold is heated by the hot air gun 12 and then enters the arc-shaped cooling mold 19. The solid composite rib is stably connected to the outer periphery of the pipe through the shaping and extruding effect of the cooling mold. At the same time, the pipe is in a state of rotation, and the solid composite rib is spirally wound and fixed on the outer periphery of the pipe.

[0015] Further, the solid composite rib manufacturing mechanism comprises the extruder 1, the forming machine 2, two groups of air-cooling molds and one group of water-cooling molds. The addition of one group of air-cooling molds can increase the moving path of the composite rib blank in the air-cooling mold, prolong the slow cooling and solidification process and make the forming shrinkage of the solid composite rib more balanced.

[0016] Further, in order to make the whole device to process the solid composite reinforcement after, can be in the outer periphery of the pipeline spiral winding welding connection of solid composite reinforcement, realize the installation connection of solid composite reinforcement manufacturing mechanism and solid composite reinforcement bending and bonding mechanism, the equipment also includes a stand 14, the stand 14 can be fixedly arranged on the ground, one side of the stand 14 is provided with a connecting frame 15, the solid composite reinforcement manufacturing mechanism is installed on the connecting frame 15. The other side of the stand 14 is provided with a cross bar 16, the end of the cross bar 16 is provided with a longitudinal bar 17, the longitudinal bar 17 is provided with a composite reinforcement bending and extruding device 13. The solid composite reinforcement manufacturing mechanism is perpendicular to the axis position of the pipeline, the composite reinforcement bending and extruding device 13 is located on the upper side of the pipeline, and the processed solid composite reinforcement can be directly spiral welded to the outer periphery of the pipeline under the action of the composite reinforcement bending and extruding device 13.

[0017] Further, in order to realize the extrusion molding of the in-mold composite reinforcement type embryo, the opposite inner sides of the air-cooled forming box 4 and the water-cooled forming box 9 are inclined, and the top width of the air-cooled forming box 4 and the water-cooled forming box 9 is greater than the bottom width, so that the processed composite reinforcement cross section is a solid triangle.

[0018] The opposite inner sides of the air-cooled forming box 4 are provided with a plurality of cold pressure forming vertical ribs 18, which are uniformly and spacedly arranged along the length direction of the air-cooled forming box 4. The cold pressure forming vertical ribs 18 can extrude the composite reinforcement type embryo inward during the molding process, reduce the contact area between the composite reinforcement type embryo and the two side molds, increase the contact pressure, and make the composite reinforcement type embryo quickly form. Without the cold pressure forming vertical ribs, the composite reinforcement type embryo cannot be flattened, and the cooling molding process first uses air cooling to slowly cool and solidify, and then uses water cooling to quickly cool and solidify, so that the composite reinforcement type embryo can shrink more evenly and maintain the flatness of the composite reinforcement type embryo.

[0019] Further, a plurality of third air-cooled pipes 20 are installed between the forming machine 2 and the air-cooled mold, which can preliminarily blow and cool the reinforcing bar type embryo with steel wires extruded from the forming machine 2. The raw material enters the forming machine 2 for preliminary molding, and the steel wires are sent into the forming machine 2 for pre-burying. After extrusion, the composite reinforcement type embryo is first blown and cooled by the third air-cooled pipe 20, and then enters the subsequent air-cooled mold and water-cooled mold for cooling and solidification. The solid composite reinforcement with steel wires has better ring stiffness effect, and can also reduce the production raw material compared with the hollow composite reinforcement.

[0020] The solid wall high edge polyethylene steel wire composite reinforcing bar produced by the equipment and process is completely different from the current clara pipe, steel belt composite corrugated pipe, vertical steel belt composite pipe, inverted u-shaped steel wire composite pipe and hollow double-bar steel wire composite pipe. The reinforcing bar has the same ring stiffness, and the weight and cost of the reinforcing bar can be reduced by 1-4 times compared with other composite pipes. The ring stiffness of the pipe is increased by about 3 times compared with ordinary polyethylene steel wire composite pipes.

[0021] The technical solutions of the utility model are not limited to the scope of the embodiments described in the utility model. The technical content not described in the utility model is well-known technology.
