Description

Technical Field

[0001] This utility model relates to the field of PVC power pipe production technology, specifically to a PVC power pipe production equipment. Background Technology

[0002] PVC power conduit is a type of plastic pipe specifically used for the protection of power system cables. Its full name is polyvinyl chloride (PVC) power cable protection pipe. PVC is a semi-crystalline plastic; when cut, the material undergoes elastic deformation and plastic flow under the pressure of the cutting tool. When the tool penetrates the pipe wall, the different directions of stress release on the inner and outer sides cause tearing fractures at the edges, forming burrs. For example, the inner side develops inward burrs due to tool compression, while the outer side develops outward burrs due to material peeling.

[0003] The utility model patent with announcement number CN217475575U discloses a C-PVC power pipe grinding device, which includes a workbench. A first vertical plate is fixedly installed at the center of one side of the top surface of the workbench. A round rod is fixedly installed on one side of the first vertical plate. Two vertically axially displaced top plates are provided on the outer surface of the round rod. A horizontally axially displaced grinding wheel is provided on the other side of the top surface of the workbench. The grinding wheel grinds the end face of the PVC power pipe.

[0004] PVC power pipes have different wall thicknesses depending on the application scenario. After the PVC power pipe is cut, due to the characteristics of the cutting process, burrs will be generated on the inner and outer walls near the end face of the power pipe, either inward or outward. In some existing technologies, such as the aforementioned patent, when polishing the power pipe, only one large polishing wheel is used to completely abut against the end face of the power pipe. During polishing, it is impossible to polish the burrs on the inner and outer walls of the end of the power pipe. Utility Model Content

[0005] The purpose of this invention is to provide a PVC power pipe production equipment to address the aforementioned shortcomings in the prior art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a PVC power pipe production equipment, comprising a frame, a rotating disk rotatably mounted on the frame, two fixed plates fixedly mounted on the rotating disk, an abutment plate slidably mounted on each fixed plate, a grinding block for grinding the end face of the power pipe fixedly mounted on the side of each abutment plate away from the fixed plate, two sliding grooves formed on each abutment plate, a sliding plate slidably mounted in each sliding groove, and a grinding rod for grinding the inner and outer walls of the power pipe slidably mounted on each sliding plate; a driving mechanism, comprising a screw rotatably mounted on the frame, a threaded sleeve threadedly connected to the screw, and a push plate fixedly mounted on the threaded sleeve.

[0007] Preferably, a second spring is fixedly provided between each of the abutting plates and the corresponding fixing plate, and a push rod is fixedly provided at the end of each abutting plate near the rotating disk, and each push rod is slidably connected to the corresponding fixing plate.

[0008] Preferably, each of the slide plates has a support frame fixedly installed at the end away from the grinding rod, each support frame has a rotating column rotatably installed on it, each fixed plate has a drive frame fixedly installed at both ends, and each rotating column is movably installed in each drive frame.

[0009] Preferably, each of the grinding rods has a movable rod fixedly installed at both ends, the movable rod is slidably connected to the corresponding slide plate, and a first spring is fixedly installed between each of the grinding rods and each slide plate in a one-to-one correspondence.

[0010] Preferably, a lower clamping plate is slidably mounted on the frame, and a second hydraulic cylinder is fixedly mounted on both sides of the lower clamping plate.

[0011] Preferably, a fixing frame is fixedly installed on the frame, a first hydraulic cylinder is fixedly installed on the top of the fixing frame, and an upper clamping plate is fixedly installed on the bottom of the first hydraulic cylinder.

[0012] In the above technical solution, the present invention provides a PVC power pipe production equipment, which has the following beneficial effects: the PVC power pipe is pushed to the abutment plate by the push plate, so that the end face of the power pipe abuts against the grinding block. As the power pipe continues to move, the sliding plate is driven by the drive frame to move, so that the grinding rod abuts against the inner and outer walls of the end face of the power pipe. Thus, when the rotating disc is rotated, the end face of the power pipe and the inner and outer walls near the end face can be ground. At the same time, the grinding rod can be adapted to PVC power pipes with different wall thicknesses through the cooperation of the first spring and the sliding plate. Attached Figure Description

[0021] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0022] Please see Figure 1-5A PVC power pipe production equipment, the technical solution of this utility model includes a frame 1, a rotating disk 13 rotatably mounted on the frame 1, two fixed plates 14 fixedly mounted on the rotating disk 13, an abutment plate 16 slidably mounted on each fixed plate 14, a grinding block 27 for grinding the end face of the power pipe fixedly mounted on the side of each abutment plate 16 away from the fixed plate 14, two sliding grooves 17 formed on each abutment plate 16, a sliding plate 18 slidably mounted in each sliding groove 17, and a grinding rod 19 for grinding the inner and outer walls of the power pipe slidably mounted on each sliding plate 18; drive The moving mechanism includes a screw 2 rotatably mounted on the frame 1, a threaded sleeve 3 threadedly connected to the screw 2, and a push plate 4 fixedly mounted on the threaded sleeve 3; the grinding rod 19 is a semi-circular cylinder, and two fixed plates 14 are symmetrically arranged near the outer circumference of the rotating disk 13. The distance between the centers of the two abutment plates 16 is adapted to the diameter of the PVC power pipe. Two sliding grooves 17 on the abutment plates 16 are symmetrically arranged, and two sliding plates 18 on the same abutment plate 16 are also symmetrically arranged. In the initial state, each sliding plate 18 is located at the end of the corresponding sliding groove 17 away from the grinding rod 19. The screw 2 is rotatably mounted on the frame 1. Below the frame 1, the push plate 4 is located at the end of the frame 1 furthest from the rotating disk 13. The frame 1 has a moving groove 12 for the push plate 4 to move. The moving groove 12 also limits the push plate 4, preventing the threaded sleeve 3 from rotating with the screw 2. When grinding the end of the PVC power pipe is required, the PVC power pipe is placed on the frame 1, and the screw 2 is rotated to cause the threaded sleeve 3 to move the push plate 4 closer to the rotating disk 13. As the push plate 4 moves, it abuts against the end of the PVC power pipe furthest from the rotating disk 13 and pushes the power pipe forward. During the movement of the PVC power pipe, it approaches... The rotating disk 13 tube extends between the two grinding rods 19 on the same abutment plate 16. As the push plate 4 continues to push, the end face of the PVC power pipe abuts against the grinding block 27. At this time, if the PVC power pipe is pushed further, each grinding rod 19 will move closer to the wall of the PVC power pipe and abut against it. The two grinding rods 19 on the same abutment plate 16 abut against the inner and outer walls of the power pipe, respectively. At this time, the rotating disk 13 is rotated, and the rotating disk 13 drives the fixed plate 14 and the abutment plate 16 to rotate, so that the grinding rods 19 grind the inner and outer walls of the power pipe, and the grinding block 27 grinds the end face of the power pipe.

[0023] Specifically, each abutment plate 16 is fixedly provided with a second spring 26 between itself and the corresponding fixed plate 14. Each abutment plate 16 is fixedly provided with a push rod 25 at one end near the rotating disk 13. Each push rod 25 is slidably connected to the corresponding fixed plate 14. Both the frame 1 and the rotating disk 13 are provided with movable slots 15 for the push rods 25 to move. When the push plate 4 pushes the power tube to abut against the grinding block 27, each grinding rod 19 does not abut against the inner or outer wall of the power tube. At this time, if the power tube is pushed to move, the grinding block 27 abuts tightly against the end face of the power tube, the second spring 26 is compressed, and the end of the push rod 25 away from the abutment plate 16 extends into the corresponding movable slot 15. At this time, each grinding rod 19 moves towards the tube wall and abuts against the tube wall. When the power tube is removed, the abutment plate 16 and the grinding rod 19 are reset by the second spring 26.

[0024] Specifically, each slide plate 18 has a support frame 22 fixedly installed at the end away from the grinding rod 19, and a rotating column 23 is rotatably installed on each support frame 22. Each fixed plate 14 has a drive frame 24 fixedly installed at both ends, and each rotating column 23 is movably installed within its corresponding drive frame 24. Each drive frame 24 is inclined, and each drive frame 24 has a through groove (not shown in the figure) adapted to the rotating column 23. When the end of the power pipe abuts against the grinding block 27, each rotating column 23 is at the end of its corresponding through groove away from the second spring 26. At this time, the... Continue pushing the power tube towards the rotating disk 13. The power tube pushes the abutment plate 16 towards the rotating disk 13. Since each drive frame 24 is stationary, each rotating column 23 moves towards the second spring 26 through the through groove, thereby driving the corresponding slide plate 18 towards the tube wall, and then driving the grinding rod 19 to abut against the tube wall. When the power tube is removed, the second spring 26 pushes the abutment plate 16 away from the rotating disk 13, thereby resetting the rotating column 23 and opening the closed grinding rod 19.

[0025] Specifically, each grinding rod 19 has a movable rod 20 fixedly installed at both ends, and the movable rod 20 is slidably connected to the corresponding slide plate 18. Each grinding rod 19 and each slide plate 18 is fixedly connected with a first spring 21. Each grinding rod 19 has two movable rods 20 fixedly installed, and both movable rods 20 are slidably connected to the corresponding slide plate 18. When the drive frame 24 drives the slide plate 18 to move closer to the wall of the power pipe, it causes the grinding rod 19 to abut against the inner and outer walls of the power pipe. As the power pipe pushes the abutment plate 16 to move, the slide plate 18 gradually moves closer to the pipe wall. At this time, the first spring 21 is compressed. When the power pipe moves away from the slide plate 18 and resets, the grinding rod 19 can be reset by the first spring 21.

[0026] Specifically, a lower clamping plate 9 is slidably mounted on the frame 1, and a second hydraulic cylinder 8 is fixedly mounted on both sides of the lower clamping plate 9. The second hydraulic cylinder 8 is fixedly mounted at the bottom of the frame 1, and one end of the second hydraulic cylinder 8 is fixedly connected to the bottom sides of the lower clamping plate 9. The lower clamping plate 9 is V-shaped. When it is necessary to grind the end of the PVC power pipe, the PVC power pipe is placed on the lower clamping plate 9, and the two second hydraulic cylinders 8 are activated at the same time to move the lower clamping plate 9 up and down, thereby adjusting the height of the PVC power pipe so that the end face of the power pipe is aligned with the grinding block 27.

[0027] Specifically, a fixed frame 5 is fixedly installed on the frame 1, a first hydraulic cylinder 6 is fixedly installed on the top of the fixed frame 5, and an upper clamping plate 7 is fixedly installed on the bottom of the first hydraulic cylinder 6. The moving end of the bottom of the first hydraulic cylinder 6 is fixedly connected to the upper clamping plate 7. When the second hydraulic cylinder 8 adjusts the height of the PVC power pipe to an appropriate height, the push plate 4 moves towards the rotating disk 13 when the screw 2 is rotated. At this time, the push plate 4 pushes the PVC power pipe to move on the lower clamping plate 9. When all the grinding rods 19 are in contact with the wall of the PVC power pipe, the first hydraulic cylinder 6 is activated. The first hydraulic cylinder 6 drives the upper clamping plate 7 to move down to clamp the PVC power pipe. The upper clamping plate 7 is also V-shaped. Anti-slip rubber pads are provided at the contact positions between the upper frame plate and the lower clamping plate 9 and the wall of the PVC power pipe. After the PVC power pipe is clamped, When the rotating disk 13 is rotated, the grinding block 27 and the grinding rod 19 grind the end face and inner and outer walls of the PVC power pipe. The frame 1 is fixedly equipped with a first servo motor 10 and a second servo motor 11. The output end of the first servo motor 10 is fixedly connected to the screw 2. The first servo motor 10 drives the screw 2 to rotate forward and backward, thereby controlling the reciprocating movement of the push plate 4. The output end of the second servo motor 11 is fixedly connected to the rotating disk 13. The second servo motor 11 drives the rotating disk 13 to rotate, thereby grinding the end of the PVC power pipe. When in use, the pipe wall of the end face of the PVC power pipe is aligned with the middle position of the abutment plate 16. When the slide plate 18 moves towards the pipe wall, the compression of the first spring 21 enables the grinding rod 19 to be suitable for PVC power pipes with different wall thicknesses.

[0028] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
