Description

Technical Field

[0001] This invention relates to the field of PVC power pipe processing, and specifically to a fully automatic pipe bending device for PVC power pipes. Background Technology

[0002] PVC power pipe is a modified PVC pipe with special properties. It is mainly used as a protective conduit for power cables and can replace the steel pipes and asbestos cement pipes currently used in power systems. During construction, the outside of the pipe does not need to be reinforced with other materials; it can be backfilled directly with sand and soil.

[0003] Before use, PVC power pipes are usually bent according to the needs of use, so that the PVC power pipes are bent into the required arc, so that the PVC power pipes can be used better. Among them, a pipe bending device is required when bending PVC power pipes.

This means that workers need to feed the PVC power pipes during the bending process and remove them after processing, placing them in cooling water for cooling.

[0037] The arc ring 32 moves and flips inward on the upper surface of the conveyor belt 31. The drive motor 57 is rotatably connected to the first transmission sprocket 34 through the first transmission chain 52. One end of the pusher cylinder 47 is slidably inserted into one end of the feeding chute 14 through the feeding slide 17. A threaded hole is opened in the middle of the side of the limiting frame 41. The limiting frame 41 is sleeved on the outer surface of the threaded rod 58 through the threaded hole. The tube removal ring 46 is slidably sleeved on the outer surface of the heating column. One end of the reset spring 26 is fixedly connected to the side of the tube removal ring 46.

[0038] Through the above technical solution, the arc ring 32 can rotate inward on the upper surface of the conveyor belt 31, ensuring that the arc ring 32 can retrieve the PVC power pipe inside the cooling water pool 21. The drive motor 57 is rotatably connected to the first transmission sprocket 34 through the first transmission chain 52, thereby driving the unloading component 3 to retrieve and unload the processed PVC power pipe. One end of the pusher cylinder 47 is slidably inserted into one end of the feeding slide 17 and the feeding ramp 14, which facilitates the lateral sliding of the PVC power pipe. The side center of the limiting frame 41 has a threaded hole, which facilitates the limiting frame 41 to be sleeved on the outer surface of the threaded rod 58 through the threaded hole, thereby controlling the reciprocating sliding of the limiting frame 41 when the threaded rod 58 rotates. The tube removal ring 46 is slidably sleeved on the outer surface of the heating column. One end of the return spring 26 is fixedly connected to the side of the tube removal ring 46, which facilitates the return spring 26 to pull the tube removal ring 46 to slide and return.

[0039] A limit plug is provided on one side of the top of the cooling water pool 21 and at the edge of the return spring 26. The threaded rod 58 is rotatably connected to one end of the water wheel 28 through the second transmission chain 54 at one end. The second bending tube moving mold 211 at one end of the first cylinder 24 is movably aligned and engaged with the bending tube fixed mold 27.

[0040] Through the above technical solution, a limiting rod can be set on the top side of the cooling water pool 21 and at the edge of the return spring 26. The connecting plate 45 is slidably sleeved on the outer surface of the limiting rod, which can limit the sliding of the connecting plate 45. The threaded rod 58 is rotatably connected to one end of the water wheel 28 through the second transmission chain 54 at one end, so as to synchronously drive the water wheel 28 to rotate inside the cooling water pool 21, promote the flow of water inside the cooling water pool 21, and facilitate the automatic retrieval and unloading of PVC power pipes by the unloading component 3.

[0041] The first bending tube moving mold 210 at one end of the second cylinder 29 is movably aligned and engaged with the edge of one end of the bending tube fixed mold 27. One end of the torsion spring 42 is fixedly connected to the upper outer surface of the limit frame 41. A limit slide is opened on the outer surface of the feeding slide 17. The limit frame 41 is slidably engaged with the inside of the feeding slide 17 through the limit slide.

[0042] Through the above technical solution, one end of the torsion spring 42 can be fixedly connected to the upper outer surface of the limit frame 41, so that the torsion spring 42 can provide power for the winding reel 43 to wind up the connecting rope 44. The limit slide is opened on the outer surface of the feeding slide 17, so that the limit frame 41 can slide and engage with the inside of the feeding slide 17 through the limit slide, thereby ensuring that the threaded rod 58 drives the limit frame 41 to slide laterally when it rotates.

[0043] The adjusting roller 51 is connected to the inner surface of the first transmission chain 52 via the second transmission sprocket 53 at one end. The adjusting roller 51 is rotated and engaged with the bottom of the feeding slide 17 via the groove 18. The side of the limiting frame 41 is in contact with one end of the tension spring 16. The bottom surface of the storage frame 13 is inclined. An arc-shaped support plate is provided at the bottom of one end of the pusher cylinder 47.

[0044] Through the above technical solution, the adjusting roller 51 can be meshed with the inner surface of the first transmission chain 52 via the second transmission sprocket 53 at one end, which facilitates the drive motor 57 to drive the adjusting roller 51 to rotate synchronously. Moreover, the adjusting roller 51 is rotatably engaged with the bottom end of the feeding slide 17 via the groove 18, which facilitates the adjustment of the heating position of the PVC power pipe inside the feeding slide 17. The side of the limiting frame 41 is movably connected to one end of the tension spring 16, which can compress the tension spring 16 when the limiting frame 41 is reset and disengaged from the thread on the outer surface of the threaded rod 58. When the tension spring 16 contracts, the threaded rod 58 continues to rotate in the opposite direction. When the threaded rod 58 rotates in the forward direction, the tension spring 16 pushes the limit frame 41 to connect with the threaded connection on the outer surface of the threaded rod 58, thereby ensuring that the limit frame 41 is properly conveyed by 48. The inner bottom surface of the storage frame 13 is inclined, which allows the PVC power pipe to be automatically fed under the action of gravity. An arc-shaped support plate is set at the bottom of one end face of the pusher cylinder 47, which can support the sliding PVC power pipe and ensure that the PVC power pipe is aligned and sleeved with the heating column.

[0045] The working principle of this invention is as follows: When bending PVC power pipes, a large number of PVC power pipes are first neatly stacked inside the storage frame 13. The PVC power pipes slide along the inclined direction and eventually slide neatly into the loading ramp 14. The first group of PVC power pipes enters the loading slide 17. At the same time, the heater 12 is started to preheat the PVC power pipes inside the loading slide 17. Then, the drive motor 57 is started to rotate, thereby driving the threaded rod 58 and the adjusting roller 51 to rotate through the first transmission chain 52 and the third transmission chain 55. When the adjusting roller 51 rotates, it drives the top PVC power pipe to rotate inside the groove 18, thereby making the heater 12 evenly heat the PVC power pipes. When the threaded rod 58 rotates, the limiting frame 41 slides laterally on the outer surface of the threaded rod 58 through the threaded hole, thereby pushing the PVC power pipe inside the feeding slide 17 laterally through the pusher cylinder 47 until one end of the PVC power pipe is sleeved on the outer surface of the heating column. When the limiting frame 41 slides, it causes the winding reel 43 to wind up the loose connecting rope 44. At the same time, the tube release ring 46 is pulled back by the return spring 26, and then the drive motor 57 is controlled to rotate in the opposite direction. At the same time, the rotation speed of the drive motor 57 is reduced, so that the threaded rod 58 drives the limiting frame 41 to slowly return to its original position. At the same time, the first cylinder 24 and the second cylinder 29 are controlled to extend and run, causing the first bending moving mold 210 to engage with the bending fixed mold 27. The outer surface of the end also serves as a limiting clamp for the PVC power pipe on the outer surface of the heating column. The second bending moving mold 211 moves closer to the bending fixed mold 27, simultaneously squeezing the PVC power pipe closer to the bending fixed mold 27 until the second bending moving mold 211 and the bending fixed mold 27 are engaged and locked together. Then, the processing time is allowed. Upon completion of processing, the first cylinder 24 and the second cylinder 29 are controlled to drive the first bending moving mold 210 and the second bending moving mold 211 away from the bending fixed mold 27 and reset their sliding motion. Simultaneously, the limiting frame 41 resets on the outer surface of the threaded rod 58. During the reset process of the limiting frame 41, the winding reel 43 completely unwinds the connecting rope 44. Therefore, as the limiting frame 41 continues to slide, it pulls the connecting plate 45 laterally through the connecting rope 44. The sliding motion causes the tube-detaching ring 46 to press against the outer surface of the heating column, squeezing the PVC power pipe and causing it to fall into the cooling water tank 21 below. The water in the cooling water tank 21 cools the bent PVC power pipe, maintaining its curved shape. When the threaded rod 58 rotates forward, it drives the water wheel 28 to rotate via the second transmission chain 54, thus pushing the water in the cooling water tank 21 and propelling the PVC power pipe towards the lower feeding component 3. Simultaneously, the drive motor 57 drives the conveyor belt 31 to rotate synchronously via the first transmission chain 52, causing the arc ring 32 to move obliquely upwards from underwater along with the conveyor belt 31. When the PVC power pipe is at one end of the conveyor belt 31, the arc ring 32 scoops it up and transports it upwards.The bending process of the PVC power pipe continues until the cooled PVC power pipe is transported out of the cooling water tank 21, completing the bending process. This cycle repeats continuously. Therefore, through the coordinated operation of the feeding component 1, bending component 2, unloading component 3, pushing component 4, and driving component 5, the PVC power pipe bending device can achieve fully automatic bending of PVC power pipes, thereby improving the processing efficiency.

[0046] The foregoing has provided a detailed description of one embodiment of the present invention, but this description is merely a preferred embodiment and should not be construed as limiting the scope of the invention. All equivalent variations and modifications made within the scope of the claims of this invention should still fall within the patent coverage of this invention.
