Description

Technical Field

[0001] This utility model relates to the field of power cable processing, specifically a circumferential cutting device for power cable processing. Background Technology

[0002] Cables are conductive products consisting of one or more insulated conductors, usually encased in insulating material. They are commonly used to transmit power, signals, and data. The diameter and materials of cables vary considerably depending on the application. In actual use, cables often require the sheath to be cut at their ends.

[0003] According to Chinese Patent No. CN221150796U, a power cable cutting device is disclosed. This utility model sets up two clamping units. When the slider moves on the slide rail, the pressure blocks of the two clamping units can fix two parts of the cable. The rotating ring drives the cutter to cut the wire sheath around the cable. Then the distance between the two clamping units is widened to remove the wire sheath, thus completing the cable cutting and sheath removal.

[0004] Regarding the aforementioned patent content, a rotatable cutter is provided to cut and remove the insulation from the cable. After the cable is cut, debris may adhere to the surface of the cutter. Cleaning the debris will affect the efficiency of subsequent cutting and insulation removal of the cable by the cutter. However, if the debris is manually cleaned from the surface of the cutter, it may cut the worker's hands, thereby reducing the efficiency of cleaning the debris from the surface of the cutter. Utility Model Content

[0005] Therefore, the purpose of this utility model is to provide a circumferential cutting device for power cable processing, so as to solve the technical problem of inconvenience in cleaning the debris attached to the surface of the cutting blade.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a circumferential cutting device for processing power cables, comprising a base plate and a rotating drum. A fixed frame is installed on the outer surface of the rotating drum, and a threaded rod is threadedly connected to the fixed frame. The bottom end of the threaded rod is connected to a movable seat via a bearing. A lifting seat is installed at the bottom of the movable seat, and a cutting blade is provided at the bottom of the lifting seat. A protective component is provided on the lifting seat. The protective component includes a through groove opened inside the lifting seat, and a spring rod is installed above the inside of the through groove. A movable block is installed at the bottom end of the spring rod, and two baffles penetrating the lifting seat are provided at the bottom of the movable block. A first push rod is fixed on the outer surface of the movable block.

[0007] By adopting the above technical solution, when using the cutting blade, the operator can push the first push rod upward, causing the movable block to move upward and squeeze the spring rod, which in turn compresses the spring rod, making it easier to push the movable block upward and reset it.

[0008] Furthermore, the protective assembly also includes a slide groove formed on the outer surface of the lifting seat and a slot formed on one side of the movable block. A return spring is installed inside the slide groove, and a slider is connected to the end of the return spring. A slot is installed on one side of the slider, extending through the groove.

[0009] By adopting the above technical solution, the slider will squeeze the return spring when it slides, so that the return spring is compressed by force, which makes it easier to push the slider to return to its original position.

[0010] Furthermore, a second push rod is fixed to the outer surface of the slider, and the locking block is slidably connected to the slide groove through the slider.

[0011] By adopting the above technical solution, when the slider needs to be moved, the operator can push the slider to slide inside the groove using the second push rod.

[0012] Furthermore, support frames are installed on both sides of the top of the base plate, and a first fixing plate is fixed on one side of the support frame, with a fixing pipe installed between the two first fixing plates.

[0013] By adopting the above technical solution, the fixed tube is set so that the rotating drum can rotate inside it.

[0014] Furthermore, the interior of the fixed tube is equipped with a rotating cylinder via a bearing, and the outer wall of the rotating cylinder is fitted with a driven bevel gear.

[0015] By adopting the above technical solution, the rotation of the active bevel gear will drive the rotation of the driven bevel gear, which in turn will drive the rotating drum to rotate, and then drive the cutting blade to rotate.

[0016] Furthermore, a top plate is fixed to the top of the support frame, and a rotating shaft is connected to the top plate via a bearing, with a drive bevel gear installed at the bottom end of the rotating shaft.

[0017] By adopting the above technical solution, when the cutting blade needs to be rotated, the operator can rotate the shaft, which in turn drives the drive bevel gear to rotate.

[0018] Furthermore, both sides of the movable seat are fitted against the inner wall of the fixed frame, and the movable seat is slidably connected to the fixed frame.

[0019] By adopting the above technical solution, the movable seat can slide inside the fixed frame, thereby adjusting the position of the movable seat.

[0020] Furthermore, the two baffles are respectively attached to the outer surface and back of the cutting blade, and the height of the baffles is greater than the height of the cutting blade.

[0021] By adopting the above technical solution, the baffle can protect the cutting blade and prevent it from scratching the staff when it is not in use.

[0022] Furthermore, two second fixing plates are fixed on one side of each of the two support frames, and a wire tube is installed between every two second fixing plates. A bidirectional lead screw is installed on one side of one of the support frames via a bearing, and two threaded seats are sleeved on the outer wall of the bidirectional lead screw. A connecting plate is fixed on the top of the threaded seats. A clamping block is installed through one side of the connecting plate and the wire tube is inserted through it. The inner wall of the clamping block is provided with an anti-slip pad.

[0023] By adopting the above technical solution, when the connecting plate moves, it will drive the clamping block to move, and the clamping block will drive the anti-slip pad to move, so that the clamping block can clamp and fix the cable.

[0024] Furthermore, a limiting rod is fixed between the two support frames, the limiting rod passing through the threaded seat, and one end of the bidirectional lead screw passing through the other support frame and equipped with a handle.

[0025] By adopting the above technical solution, the limiting rod can guide the threaded seat, thereby improving the stability of the threaded seat when it moves.

[0026] In summary, the present invention has the following main advantages:

[0027] 1. This utility model features a protective component. When using the cutting blade, the operator can push the first push rod upwards, causing the movable block to move upwards and compress the spring rod. The spring rod is then compressed, and the movable block moves the baffle. The baffle then moves into the through groove and no longer obstructs the cutting blade. At this point, the cutting blade can be used to cut the cable. After the cable is cut, the baffle returns to its original position and obstructs the cutting blade, thus protecting it and preventing accidental contact with the cutting blade when not in use, which could cause scratches to the operator. At the same time, when the baffle obstructs the cutting blade, it can clean away the debris attached to the surface of the cutting blade, preventing debris from adhering to the cutting blade. This also eliminates the need for the operator to directly wipe the debris attached to the surface of the cutting blade with their hands, improving safety and increasing the efficiency of cleaning debris attached to the cutting blade surface.

[0028] 2. This utility model is equipped with a locking block, a locking groove, a slider, a return spring, and a sliding groove. When the movable block moves upward and contacts the locking block, as the movable block continues to move upward, it will push the locking block to move, so that the locking block moves into the sliding groove and squeezes the return spring. When the locking groove on the movable block is aligned with the locking block, the return spring is stretched and pushes the slider to return to its original position, so that the locking block is locked into the locking groove and thus locks and limits the movable block, preventing the movable block from moving downward at will. This prevents the baffle from moving downward and affecting the cutting efficiency of the cable when the cutting blade is cutting the cable.

[0029] 3. This utility model is provided with a first push rod to push the movable block to move, and a second push rod to push the slider to move. Attached Figure Description

[0040] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0041] The embodiments of this utility model will be described below based on its overall structure.

[0042] Example 1:

[0043] A circumferential cutting device for processing power cables, such as Figures 1-9 As shown, the device includes a base plate 1 and a rotating drum 8. A fixed frame 10 is mounted on the outer surface of the rotating drum 8, and a threaded rod 11 is threadedly connected to the fixed frame 10. The bottom end of the threaded rod 11 is connected to a movable seat 12 via a bearing. A lifting seat 13 is mounted on the bottom of the movable seat 12, and a cutting blade 14 is provided on the bottom of the lifting seat 13. A protective component 9 is also provided on the lifting seat 13. Support frames 2 are mounted on both sides of the top of the base plate 1, and a first fixed plate 3 is fixed to one side of the support frame 2. A fixed tube 4 is installed between the two first fixed plates 3. The fixed tube 4 is designed so that the rotating drum 8 can rotate inside it. The rotating drum 8 is mounted inside the fixed tube 4 via a bearing, and a driven bevel gear 7 is mounted on the outer wall of the rotating drum 8. After the driving bevel gear 6 rotates, The driven bevel gear 7 will rotate, which in turn will rotate the drum 8, and then the cutting blade 14 will rotate. The top of the support frame 2 is fixed with a top plate 23. The top plate 23 is connected to the rotating shaft 5 through a bearing. The bottom of the rotating shaft 5 is equipped with a driving bevel gear 6. When the cutting blade 14 needs to be rotated, the operator can rotate the rotating shaft 5, which will drive the driving bevel gear 6 to rotate. Both sides of the movable seat 12 are in contact with the inner wall of the fixed frame 10. The movable seat 12 is slidably connected to the fixed frame 10 so that the movable seat 12 can slide inside the fixed frame 10, thereby adjusting the position of the movable seat 12. The top of the rotating shaft 5 is connected to a handle. The driving bevel gear 6 meshes with the driven bevel gear 7, making it convenient for the operator to rotate the rotating shaft 5 through the handle.

[0044] See Figures 1-8The protective component 9 includes a through groove 901 inside the lifting seat 13, and a spring rod 902 is installed above the inside of the through groove 901. A movable block 903 is installed at the bottom of the spring rod 902, and two baffles 904 penetrating the lifting seat 13 are provided at the bottom of the movable block 903. A first push rod 905 is fixed on the outer surface of the movable block 903. When the cutting blade 14 is used, the operator can push the first push rod 905 upward, so that the movable block 903 moves upward and squeezes the spring rod 902. The spring rod 902 is compressed by force, which facilitates the subsequent pushing of the movable block 903 upward. The two baffles 904 are respectively attached to the outer surface and back of the cutting blade 14. The height of the baffles 904 is greater than the height of the cutting blade 14. The baffles 904 can shield and protect the cutting blade 14 to prevent the cutting blade 14 from scratching the operator when it is not in use.

[0045] Example 2:

[0046] Based on the above embodiment 1, in order to facilitate the locking and limiting of the movable block 903 and prevent it from moving down arbitrarily, the following structure will be set.

[0047] Specifically, the protective component 9 also includes a slide groove 907 formed on the outer surface of the lifting seat 13 and a slot 906 formed on one side of the movable block 903. A return spring 908 is installed inside the slide groove 907, and a slider 909 is connected to the end of the return spring 908. A slot 910 extending through the through groove 901 is installed on one side of the slider 909. When the slider 909 slides, it will squeeze the return spring 908, causing the return spring 908 to be compressed, which facilitates the subsequent push of the slider 909 to return to its original position. The outer surface of 9 is fixed with a second push rod 911. The locking block 910 is slidably connected to the slide groove 907 via the slider 909. The bottom of the locking block 910 and the top side of the movable block 903 are both set with slopes. The locking block 910 is adapted to the locking groove 906, so that when the movable block 903 moves upward, it can push the locking block 910 to move. The locking block 910 is slidably connected to the slide groove 907 via the slider 909. When the slider 909 needs to be moved, the operator can push the slider 909 to slide inside the slide groove 907 via the second push rod 911.

[0048] Example 3:

[0049] Based on the above embodiment one, in order to facilitate the clamping and fixing of the cable so that the cable can be cut, the following structure will be set.

[0050] See Figures 1-5Two second fixing plates 21 are fixed on one side of each of the two support frames 2, and a wire tube 22 is installed between every two second fixing plates 21. A double-acting screw 15 is installed on one side of one support frame 2 via a bearing, and two threaded seats 16 are sleeved on the outer wall of the double-acting screw 15. A connecting plate 17 is fixed on the top of the threaded seats 16. A clamping block 18 is installed on one side of the connecting plate 17 through the wire tube 22. An anti-slip pad 19 is provided on the inner wall of the clamping block 18. When the connecting plate 17 moves, it will drive the clamping block 18 to move, and the clamping block 18 will drive the anti-slip pad 19 to move, so that the clamping block 18 can clamp and fix the cable. One end of the double-acting screw 15 passes through the other support frame 2 and is equipped with a handle.

[0051] Example 4:

[0052] Based on the above embodiment 3, in order to improve the stability of the threaded seat 16 when it moves and prevent the threaded seat 16 from rotating, it is necessary to guide it. Therefore, the following structure will be set.

[0053] Specifically, a limiting rod 20 is fixed between the two support frames 2. The limiting rod 20 passes through the threaded seat 16 and can guide the threaded seat 16, thereby improving the stability of the threaded seat 16 when it moves.

[0054] The working principle of this utility model is as follows: First, in use, the operator can pass the cable to be cut between the two conductor tubes 22. Then, by rotating the bidirectional lead screw 15, the two threaded seats 16 move, which in turn moves the connecting plate 17 and the clamping block 18. The clamping block 18 can clamp and fix the cable. Next, the operator pushes the movable block 903 upward through the first push rod 905. The movable block 903 squeezes the spring rod 902, causing the spring rod 902 to be compressed. This then moves the baffle 904, causing the baffle 904 to move. When the movable block 903 moves upward and contacts the locking block 910, it will push the locking block 910 to move as the movable block 903 continues to move upward, so that the locking block 910 moves into the slide groove 907 and squeezes the return spring 908. When the locking groove 906 on the movable block 903 is aligned with the locking block 910, the return spring 908 is stretched and pushes the slider 909 to return to its original position, so that the locking block 910 is locked into the locking groove 906 and thus locks and limits the movable block 903 to prevent the movable block 903 from moving downward at will.

[0055] Next, the operator rotates the threaded rod 11, causing it to move down and move the movable seat 12 down, which in turn moves the lifting seat 13 down, and then moves the cutting blade 14 down, pressing it against the cable sheath to cut it. Then, the operator rotates the rotating shaft 5, which drives the driving bevel gear 6 to rotate, which in turn drives the driven bevel gear 7 to rotate. The driven bevel gear 7 then drives the rotating drum 8 to rotate, which in turn drives the fixed frame 10 and the cutting blade 14 to rotate, so as to perform circumferential cutting on the cable sheath.

[0056] After the circumferential cutting process, the operator rotates the threaded rod 11 in the opposite direction, causing the threaded rod 11 to move upward, which in turn moves the movable seat 12 upward, and then moves the cutting blade 14 upward and resets. Then, the second push rod 911 pushes the slider 909 to move, and the slider 909 moves the locking block 910, causing the locking block 910 to move out of the slot 906 and no longer limit the movable block 903. At this time, the spring rod 902 extends and pushes the movable block 903 to reset and move, which in turn moves the baffle 904 to reset and move and block the cutting blade 14, so as to protect the cutting blade 14 and prevent the cutting blade 14 from accidentally touching the cutting blade 14 when it is not in use, which could cause scratches to the operator. At the same time, when the baffle 904 blocks the cutting blade 14, it can clean the debris attached to the surface of the cutting blade 14, preventing the debris from adhering to the cutting blade 14.
