This product has the characteristics of high strength, excellent flexibility and toughness, high temperature resistance, corrosion resistance, flame retardancy, good insulation performance, no pollution, not easy to deteriorate, light weight, and high workability. The performance of the product is far superior to that of traditional asbestos conduit and ordinary PVC pipe, and it is an ideal replacement for traditional power cable protection pipe. Traditional CPVC conduit needs to flare the ends during the manufacturing process to meet the needs of connecting two conduits, and a flare processing device is used for the flaring operation.

By providing a push structure, the electric cylinder structure moves the movable plate toward the flare processing equipment, and the loading plate fixes the processed pipe inside the loading port with the clamp plate through the electric push rod, so that the processed pipe can be stably moved in front of the flare processing equipment, and mechanized work is used in the entire moving process, avoiding the problem of pipe misalignment during manual pushing, which reduces the flare processing accuracy, resulting in non-standard installation of the joints afterwards, ensuring the connection standard of the conduit, and reducing the labor intensity of the workers.

[0004] The conduit flaring machine according to the above-mentioned patent document still has some obvious shortcomings in the actual use process. After heating and flaring, the machine needs to pull the conduit out from the electric heat flaring punch, and the end of the heated conduit is easily attached to the electric heat flaring punch under the heating action, and the flaring part is easily damaged when directly pulled out. Therefore, the present invention solves the problems existing in the prior art and proposes a flaring device for manufacturing CPVC conduit, which can separate one end of the conduit from the electric heat flaring punch when pulling out the conduit, making it easy to pull out.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0024] Hereinafter, the technical means in the embodiments of the present invention will be described in detail with reference to the drawings in the embodiments of the present invention. It goes without saying that the described embodiments are only some of the embodiments of the present invention, and are not all of the embodiments. The specific embodiments described herein are used only to interpret the present invention, and are not intended to limit the present invention. All other embodiments obtained based on the embodiments of the present invention without the need for creative activity by those skilled in the art are all within the scope of protection of the present invention.

[0025] The present invention provides a flare processing device for manufacturing CPVC conduit, as shown in Figures 1 to 6, which comprises a bottom plate 1 and a CPVC conduit body 2, with positioning holes 3 drilled in the four corners of the top of the bottom plate 1. By providing the bottom plate 1, the other structures of the device can be supported by using the bottom plate 1 as a base, and the positioning holes 3 drilled in the surface of the bottom plate 1 can fix the position in which the device is used, and when installing, the user can fix the bottom plate 1 to the installation base surface with mounting bolts, mounting screws, etc.

[0026] Preferably, two sets of holders 4 are attached to the top of the bottom plate 1, and a through groove 5 is drilled on the surface of the holder 4 to match the CPVC electric conduit body 2, and the surface of the CPVC electric conduit body 2 is in sliding contact with the inner wall of the through groove 5.

[0027] Specifically, the holders 4 and the through grooves 5 work together to support and position the CPVC conduit body 2, and when the CPVC conduit body 2 is moved and one end is aligned with the flaring assembly, the two sets of holders 4 and through grooves 5 work together to support the CPVC conduit body 2, and when the CPVC conduit body 2 moves, its surface moves within the internal cavity of the through grooves 5, improving the stability of the movement.

[0028] A sliding assembly is provided between the through groove 5 and the CPVC conduit body 2, and the sliding assembly has an annular arrangement of mounting holes 8 installed on the inner wall of the through groove 5, and a ball 9 is rotatably connected to the inner cavity of the mounting hole 8, one side of the ball 9 extends through the mounting hole 8 into the inner cavity of the through groove 5, and the side of the ball 9 located in the inner cavity of the mounting hole 8 is rollably connected to the surface of the CPVC conduit body 2.

[0029] By providing the sliding assembly, the frictional force between the surface of the CPVC conduit body 2 and the inner wall of the through groove 5 is reduced, and it is possible to prevent scratches on the surface caused by the surface of the CPVC conduit body 2 sliding within the internal cavity of the through groove 5 during movement. By providing the ball 9, when the CPVC conduit body 2 is moved, its surface comes into contact with the ball 9, and as the CPVC conduit body 2 moves, the ball 9 rotates in the internal cavity of the mounting hole 8, so that the frictional force between the CPVC conduit body 2 and the inner wall of the through groove 5 can be reduced.

[0030] It is noteworthy that a flare processing assembly for flaring the CPVC conduit body 2 is attached to one side of the top of the bottom plate 1 at a corresponding location of the CPVC conduit body 2, the flare processing assembly has a casing 21 movably attached to one side of the top of the bottom plate 1, a flaring mold 22 is fixed to one side of the casing 21, the cross section of the flaring mold 22 is arranged in a stepped shape, a drive cylinder 23 is connected and fixed to one side of the casing 21, an electric heat type flare processing punch 24 is connected and fixed to the point where the telescopic end of the drive cylinder 23 penetrates the casing 21 and extends to the outside of the casing 21, and the surface of the electric heat type flare processing punch 24 is in sliding contact with the internal cavity of the flaring mold 22.

[0031] By providing the flaring assembly, after one end of the CPVC conduit body 2 is inserted into the inner cavity of the flaring mold 22, the one end of the CPVC conduit body 2 abuts against the step of the inner cavity of the flaring mold 22. At this time, the user turns on the driving cylinder 23 via the external controller, and after the driving cylinder 23 is connected to an external air source, the telescopic end moves the electric heat type flaring punch 24 to one end of the CPVC conduit body 2, so that the electric heat type flaring punch 24 enters the one end of the CPVC conduit body 2 to heat the CPVC conduit body 2 for flaring. It is worth noting that the housing of the electric heat type flaring punch 24 is an aluminum housing, and an electric heating wire is attached inside.

[0032] It should be noted that in this embodiment, as shown in Fig. 6, the casing 21 and the bottom plate 1 are connected by a movable connection method. When the flaring process is completed and the CPVC conduit body 2 is to be removed, the user can rotate the casing 21 to pull out the CPVC conduit body 2 from the end close to the casing 21, because after the flaring process of the CPVC conduit body 2 is completed, the diameter of the flaring part is larger than the diameter of the through groove 5, and the CPVC conduit body 2 cannot be pulled out from the through groove 5 along the original route. It should also be noted that, due to the movable connection between the casing 21 and the bottom plate 1, after the CPVC conduit body 2 is removed, the casing 21 needs to be returned to its original position to ensure that the flaring mold 22 and the through groove 5 are in a coaxial state. Under this state, in order to lock and fix the use position of the casing 21, it is necessary to use a locking structure to lock the casing 21 and the bottom plate 1. The above locking structure can use a fixed pin structure, but is not limited to the fixed pin structure. Those skilled in the art can select a suitable locking structure according to actual use needs to use it to lock and position the casing 21 of the present invention, so detailed description thereof will be omitted here.

[0033] The flare processing assembly is also equipped with a cooling assembly, which is attached to the top of the bottom plate 1 and includes a housing 25 fixed to the surface of the flaring mold 22. A cooling case 26 is connected and fixed to the top of the bottom plate 1. An injection tube 32 is attached to the top of the cooling case 26. A cap is attached to the top end of the injection tube 32. A semiconductor cooling sheet 27 is fixed in the internal cavity of the cooling case 26. The heat dissipation end of the semiconductor cooling sheet 27 passes through the cooling case 26. 2, and extends to the outside of the cooling case 26. A pump 28 is fixed to one side of the cooling case 26 at the top of the bottom plate 1. The suction side of the pump 28 is connected to an inlet pipe 29, the end of the inlet pipe 29 remote from the pump 28 is connected to one side of the cooling case 26, the discharge side of the pump 28 is connected to a drain pipe 30, the end of the drain pipe 30 remote from the pump 28 is connected to the surface of the housing 25, a return pipe 31 is connected to the bottom of the housing 25, and the bottom end of the return pipe 31 is connected to the top of the cooling case 26.

[0034] After the flaring process of one end of the CPVC conduit body 2 is completed, the user turns on the pump 28 via the external controller, and the operation of the pump 28 pumps up the cooling liquid in the cooling case 26 through the inlet pipe 29 and discharges it into the internal cavity of the housing 25 through the drain pipe 30, thereby cooling the flared portion of the CPVC conduit body 2 and quickly forming its shape. The provision of the semiconductor cooling sheet 27 allows the cooling liquid in the cooling case 26 to be cooled. The provision of the return pipe 31 allows the cooling liquid after absorbing heat to be returned to the internal cavity of the cooling case 26 and re-cooled, thereby achieving the purpose of circulating cooling.

[0035] Furthermore, the two sets of holders 4 are movably connected to two sets of connecting rods 6 via a rotating assembly, the rotating assembly has a rotating groove 18 drilled into the inside of the two sets of holders 4, and an annular rotating plate 19 is rotatably connected to the internal cavity of the rotating groove 18. Both ends of the connecting rod 6 are respectively connected and fixed to the surfaces of the two sets of annular rotating plates 19. A fixed shell 7 is fixed between the two sets of connecting rods 6, and connecting grooves 20 aligned with the connecting rods 6 are drilled on both sides of the fixed shell 7, and the surfaces of the connecting grooves 20 are connected and fixed to the surfaces of the connecting rods 6.

[0036] By providing the rotating assembly, the stability of the movement of the connecting rod 6 and the fixed shell 7 can be improved, and when the CPVC conduit body 2 is rotated, the fixed shell 7 and the connecting rod 6 rotate together, and the rotation of the connecting rod 6 causes the annular rotating plate 19 to rotate in the inner cavity of the rotating groove 18, thereby achieving the purpose of improving the rotation stability of the connecting rod 6 and the fixed shell 7. By providing the connecting groove 20, the fixed shell 7 can be fixed to the surface of the connecting rod 6.

[0037] Preferably, a positioning assembly for fixing the fixed shell 7 and the CPVC conduit body 2 is attached to the top of the fixed shell 7, and the positioning assembly includes an arc-shaped positioning plate 14 provided at the top of the internal cavity of the fixed shell 7, a positioning tube 15 is connected and fixed to the top of the fixed shell 7, and a positioning post 16 is screwed to the top of the positioning tube 15, and the bottom end of the positioning post 16 is inserted through the positioning tube 15 and the fixed shell 7 in order, extends to the internal cavity of the fixed shell 7, and is rotatably connected to the top of the arc-shaped positioning plate 14.

[0038] By providing the positioning assembly, when the CPVC conduit body 2 is installed, one end of the CPVC conduit body 2 passes through the two sets of through-slots 5 and the fixed shell 7 in sequence, and extends to the inner cavity of the flaring mold 22. After the one end is inserted into the inner cavity of the flaring mold 22, the user can rotate the positioning post 16. By rotating the positioning post 16, the one end moves the arc-shaped positioning plate 14 to press and fix the CPVC conduit body 2 against the inner cavity of the fixed shell 7, preventing the CPVC conduit body 2 from rattling during the flaring operation, thereby achieving the purpose of positioning and fixing the CPVC conduit body 2.

[0039] Protective rubber pads 17 are fixed to the bottom of the arc-shaped positioning plate 14 and the bottom of the internal cavity of the fixed shell 7 , and the insides of the two sets of protective rubber pads 17 are attached to the surface of the CPVC electric conduit body 2 .

[0040] By providing protective rubber pad 17, when CPVC conduit body 2 is pressed and fixed, protective rubber pad 17 is provided at the connection between arc-shaped positioning plate 14 and fixed shell 7 and CPVC conduit body 2, which prevents damage to CPVC conduit body 2 due to excessive pressing force and increases the friction between CPVC conduit body 2 and arc-shaped positioning plate 14 and fixed shell 7, thereby providing an anti-slip effect and improving the positioning effect.

[0041] It is worth noting that a drive assembly for rotating and driving the CPVC conduit body 2 is attached to the top of the bottom plate 1 at a corresponding location on the fixed shell 7, and the drive assembly includes an arc-shaped toothed plate 10 fixed to the bottom of the fixed shell 7, a drive motor 11 is fixed to the top of the bottom plate 1, a drive gear 12 is fixed to the output shaft of the drive motor 11, the bottom of the drive gear 12 meshes with the bottom of the arc-shaped toothed plate 10, a mounting bracket 13 is connected and fixed to the bottom of the drive motor 11, and the bottom of the mounting bracket 13 is connected and fixed to the top of the bottom plate 1.

[0042] By providing the driving assembly, after the flaring process of the CPVC conduit body 2 is completed and cooled to form a shape, the user needs to remove the CPVC conduit body 2 from the device. At this time, the user can turn on the driving motor 11 via the external controller, and the output shaft of the driving motor 11 rotates the arc-shaped tooth plate 10 via the driving gear 12 to rotate the CPVC conduit body 2 via the fixed shell 7, and the end of the CPVC conduit body 2 connected to the flaring mold 22 is loosely separated from the flaring mold 22, thereby preventing the problem that one end of the CPVC conduit body 2 and the flaring mold 22 are adhered to each other due to heating, making it impossible to remove the CPVC conduit body 2.

[0043] It is noteworthy that in this embodiment, the driving motor 11 is also equipped with a brake system, and when the CPVC conduit body 2 is heated and flared, the brake system locks the output shaft of the driving motor 11 to prevent the CPVC conduit body 2 from rotating during this process; after the flaring is completed, the user can reverse the positioning post 16 to release the positioning effect on the CPVC conduit body 2, so that the CPVC conduit body 2 can be smoothly pulled out of the apparatus.
