DETAILED DESCRIPTION

[0007] The device for making solid high-edge polyethylene steel wire composite reinforcement on the outer wall of a pipeline according to the present invention is as follows: Figure 1-4 As shown, it includes a solid composite rib manufacturing mechanism and a solid composite rib bending and bonding mechanism. The solid composite rib manufacturing mechanism is composed of an extruder 1, a molding machine 2, an air-cooling mold and a water-cooling mold. The extruder 1 can extrude the reinforcing rib blank with steel wire from the molding machine 2, and sequentially enter the air-cooling mold and the water-cooling mold for cooling and molding. The solid composite rib bending and bonding mechanism is composed of a hot air gun 12 and a composite rib bending and extrusion device 13. The hot air gun 12 can heat and melt the bottom surface of the solid composite rib and the outer surface of the molded pipe. The composite rib bending and extrusion device 13 can bend the solid composite rib according to the shape of the pipe and spirally wrap and weld it on the outer periphery of the pipe.

[0008] The bottom of the air-cooled mold and the water-cooled mold are both provided with a molding base plate 3, and two groups of air-cooled molding boxes 4 arranged side by side are provided on the molding base plate 3. The opposite inner side surfaces of the air-cooled molding boxes 4 are provided with first ventilation holes 5. The air-cooled molding boxes 4 are connected with first air-cooled pipes 6 connected with the inner cavity. The gas with a lower temperature in the first air-cooled pipe 6 can be blown into the air-cooled mold through the first ventilation holes 5, acting on the two sides of the internal composite ribs to achieve heat exchange and cooling. A second air-cooled pipe 7 is installed at the top between the air-cooled molding boxes 4, and a second ventilation hole 8 is provided at the bottom of the second air-cooled pipe 7. The gas with a lower temperature in the second air-cooled pipe 7 can be blown into the top of the air-cooled mold through the second ventilation holes 8 to achieve all-round air cooling in the air-cooled mold. The molding base plate 3, the second air-cooled pipe 7 and the air-cooled molding boxes 4 on both sides form a relatively closed air-cooled mold, and the air-cooled molding boxes 4 serve as side molds for composite rib molding. The air-cooled mold serves as a molding channel for the mold blank to travel, and under the heat exchange effect of the cold air, the composite rib mold blank is slowly cooled and solidified.

[0009] The molding base plate 3 is also provided with two groups of water-cooled molding boxes 9 arranged side by side. The water-cooled molding boxes 9 are connected with water injection pipes 10 connected with the inner cavity. A water-cooled top pipe 11 is installed on the top between the water-cooled molding boxes 9. Cooling water can be injected into the water-cooled top pipe 11 and the water-cooled molding boxes 9 to form heat exchange with the internal composite ribs. Compared with air cooling, the heat exchange of water cooling is faster and can quickly cool down and solidify the internal composite ribs. The molding base plate 3, the water-cooled top pipe 11 and the water-cooled molding boxes 9 on both sides form a relatively closed water-cooled mold, providing a heat exchange molding channel for water cooling of the composite ribs.

[0010] The composite rib bending and extrusion device 13 includes a longitudinal moving frame 30, which can be moved and adjusted in the length direction of the longitudinal rod 17. The longitudinal moving frame 30 can realize the driving and moving adjustment on the longitudinal rod 17 through a screw nut mechanism or a gear rack mechanism. A plurality of screw nuts 33 are installed on the longitudinal moving frame 30, and a vertically arranged screw rod 31 is installed in the screw nut 33. A handle 32 is installed at the upper end of the screw rod 31, and a template frame 34 is connected to the lower end of the screw rod 31 through a bearing 36.

[0011] An arc-shaped cooling mold 35 that matches the outer circumference of the pipe is installed on the template frame 34. The arc-shaped cooling mold 35 can be pressed against the outer circumference of the pipe by turning the handle 32. The setting of the bearing 36 can prevent the screw rod 31 from driving the template frame 34 to rotate during the rotation and lifting process, so that it maintains the set position, and realizes the precise welding and fixation of the composite ribs on the outer circumference of the pipe. The solid composite ribs extruded by the air-cooled mold and the water-cooled mold enter the arc-shaped cooling mold 35 after being heated by the hot air gun 12. Through the shaping and extrusion action of the cooling mold, the solid composite ribs are firmly connected to the outer circumference of the pipe. At the same time, the pipe is also in a state of self-rotation, and the solid composite ribs will be spirally wound and fixed on the outer circumference of the pipe.

[0012] Furthermore, the solid composite rib production mechanism consists of an extruder 1, a molding machine 2, two sets of interconnected air-cooled molds and a set of water-cooled molds. Adding a set of air-cooled molds can increase the walking path of the composite rib blank in the air-cooled mold, extend the processing steps of slow cooling and solidification, and make the molding shrinkage of the solid composite rib more balanced.

[0013] Furthermore, in order to allow the solid composite ribs to be processed and welded on the outer periphery of the pipe after the solid composite ribs are processed and manufactured by the overall device, and to realize the installation and connection of the solid composite rib manufacturing mechanism and the solid composite rib bending and bonding mechanism, the device also includes a stand 14, which can be fixedly set on the ground, and a connecting frame 15 is installed on one side of the stand 14, and the solid composite rib manufacturing mechanism is installed on the connecting frame 15. A cross bar 16 is installed on the other side of the stand 14, and a longitudinal bar 17 is installed at the end of the cross bar 16, and a composite rib bending and extrusion device 13 is installed on the longitudinal bar 17. The solid composite rib manufacturing mechanism is perpendicular to the axis of the pipe, and the composite rib bending and extrusion device 13 is located on the upper side of the pipe. The solid composite ribs at the processing location can be directly spirally welded to the outer periphery of the pipe under the action of the composite rib bending and extrusion device 13.

[0014] Furthermore, in order to realize the extrusion molding of the composite rib blank in the mold, the relative inner side surfaces of the air-cooled molding box 4 and the water-cooled molding box 9 are inclined, and the top width of the air-cooled molding box 4 and the water-cooled molding box 9 is greater than the bottom width, so that the cross-section of the processed composite rib is a solid triangle.

[0015] A plurality of cold-pressed forming ribs 18 are arranged on the opposite inner sides of the air-cooled forming box 4, and the cold-pressed forming ribs 18 are evenly spaced along the length direction of the air-cooled forming box 4. The arrangement of the cold-pressed forming ribs 18 can squeeze the composite rib blank inward during the forming process, reduce the contact area between the composite rib blank and the molds on both sides, increase the contact pressure, and make it form quickly. If there are no cold-pressed forming ribs, the composite rib blank cannot be flattened. In the cooling and forming process, air cooling is first used to slowly cool down and solidify, and then water cooling is used to quickly cool down and solidify, which can allow the composite rib blank to shrink more evenly and maintain the flatness of the composite rib blank.

[0016] Furthermore, a plurality of third air-cooling tubes 20 are installed between the molding machine 2 and the air-cooling mold. The third air-cooling tubes 20 can initially blow air to cool down the reinforcing rib blank with steel wire extruded by the molding machine 2. The raw materials enter the molding machine 2 for initial molding. At the same time, the steel wire is sent into the molding machine 2 for pre-embedding. The extruded composite rib blank is first cooled by blowing air through the third air-cooling tube 20, and then enters the subsequent air-cooling mold and water-cooling mold for cooling and solidification. The solid composite rib with steel wire has better ring stiffness and can reduce production raw materials compared with hollow composite ribs.

[0017] Furthermore, in order to allow the air-cooled mold and the water-cooled mold to process solid composite ribs of different widths, the width distance between the air-cooled forming boxes 4 or the water-cooled forming boxes 9 on both sides is adjusted as needed, such as Figure 6 As shown, the air-cooled forming box 4 and the water-cooled forming box 9 on one side are provided with a long plate 21, and a long groove 22 is opened on the long plate 21. The forming bottom plate 3 is provided with a positioning bolt 23 matched with the long groove 22. The long plate 21 can be locked on the forming bottom plate 3 by rotating the positioning bolt 23. After loosening the positioning bolt 23, the position of the positioning bolt 23 in the long groove 22 can be adjusted to adjust the installation position of the forming box on the forming bottom plate 3.

[0018] In order to allow the molding boxes on both sides to float elastically within a certain range during the extrusion molding of the solid composite rib blank and avoid blockage during the molding process, an elastic feed adjustment mechanism is installed between the air-cooled molding box 4 and the water-cooled molding box 9 on the other side and the molding base plate 3. The elastic feed adjustment mechanism always has a tendency to move the two air-cooled molding boxes 4 or the two water-cooled molding boxes 9 closer to each other.

[0019] The elastic feed adjustment mechanism includes a first vertical plate 24 disposed on the molding bottom plate 3, an adjustment screw 25 is installed on the first vertical plate 24, and adjustment nuts 26 are installed on the outer periphery of the adjustment screws 25 on both sides of the first vertical plate 24, and the adjustment nuts 26 can lock the adjustment screws 25 on the first vertical plate 24. Corresponding to the position of the adjustment screw 25, a convex column 27 is provided on the air-cooled molding box 4 and the water-cooled molding box 9, and a first spring 28 is installed between the adjustment screw 25 and the convex column 27. The adjustment nut 26 is rotated to change the relative position of the adjustment screw 25 on the first vertical plate 24, so as to adjust the initial pre-tightening pressure of the first spring 28 on the air-cooled molding box 4 and the water-cooled molding box 9 and the distance between the air-cooled molding boxes 4 on both sides and the water-cooled molding boxes 9 on both sides.

[0020] Furthermore, in order to realize the elastic floating limit between the molding boxes on both sides, an elastic floating amplitude limit device is installed between the air-cooled molding box 4, the water-cooled molding box 9 and the molding bottom plate 3, such as Figure 7As shown, the elastic floating amplitude limiting device includes a slide rail 37 arranged on the forming base plate 3, and a limiting slider 38 is installed on the slide rail 37. A second vertical plate 39 is installed at the end of the slide rail 37 away from the forming box, and a limiting screw 29 is installed on the second vertical plate 39. One end of the limiting screw 29 is in contact with the limiting slider 38. Rotating the limiting screw 29 can tighten the limiting slider 38 to the air-cooled forming box 4 and the water-cooled forming box 9. The elastic limiting amplitude of the air-cooled forming box 4 and the water-cooled forming box 9 in the width direction is realized by the limiting slider 38. When it is necessary to produce composite rib blanks of different widths, the limiting slider 38 can be adjusted by rotating the limiting screw 29 to limit the elastic limit position of the forming box, so as to ensure that the processed composite rib blank does not exceed the set width, thereby improving the processing quality of the composite rib blank.

[0021] The process for making solid high-edge polyethylene steel wire composite reinforcement on the outer wall of a pipeline is characterized by comprising the following steps: ① an extruder 1 extrude a reinforcement rib blank with steel wire from a molding machine 2; ② The rib-reinforced blank is extruded to the position of the third air-cooling tube 20 for preliminary cooling and forming, and then enters the air-cooling mold for secondary cooling and forming; ③ The cooling air with reduced temperature is blown into the air-cooled mold, and under the shaping and guiding action of the air-cooled forming boxes 4 on both sides, the composite ribs are slowly cooled and solidified according to the shape to be processed; ④ After air cooling and solidification, the composite rib enters the water-cooling mold, and cooling water is introduced into the water-cooling forming boxes 9 on both sides and the water-cooling top pipe 11. Under the shaping and guiding action of the water-cooling forming boxes 9 on both sides, the composite rib is rapidly cooled and solidified according to the shape to be processed, and a formed composite rib is obtained; ⑤ The hot air gun 12 is started to heat and melt the bottom of the formed composite rib and the periphery of the formed pipe. The composite rib bending and extrusion device 13 bends the formed composite rib according to the shape of the pipe and applies a pressing force to the composite rib, so that the composite rib is spirally wound and welded to the periphery of the pipe.

[0022] The solid wall high edge polyethylene steel wire composite reinforcement produced by this equipment and process is completely different from the current carat tube, steel belt composite corrugated pipe, vertical steel belt composite pipe, inverted U-shaped steel wire composite pipe and cavity double-reinforced steel wire composite pipe. The same ring stiffness of this reinforcement can reduce the weight and cost of reinforcement of other composite pipes by 1-4 times. The pipeline ring stiffness is about 3 times higher than that of ordinary polyethylene steel wire composite pipes.

[0023] The technical solution of the present invention is not limited to the scope of the embodiments described in the present invention. The technical contents not described in detail in the present invention are all well-known technologies.
