Description

Technical Field

[0001] This utility model relates to a multifunctional cable stripping tool. Background Technology

[0002] Typically, cables have a complex structure, including multiple layers such as conductor, insulation layer, shielding layer, lead sheath layer, sheath layer, filling layer, and armor layer. When performing cable maintenance work, operators need to carry the appropriate tools to strip the cable structure according to the different cables.

[0003] A careful analysis of existing tools used for cable stripping reveals the following problems:

[0004] First, many existing wire stripping tools are only suitable for specific types and specifications of cables, and their functions are relatively limited, which restricts their application range and practicality.

[0005] Second, wire strippers are prone to wear after frequent use, and existing wire stripping tools are inconvenient to disassemble and replace.

[0006] Third, during manual operation, especially when it is necessary to strip multiple cable structures such as lead sheath and sheath, multiple sets of cutting tools are required to strip the corresponding structures. This results in low portability, cumbersome operation steps, and difficulty in meeting the needs of rapid operation.

[0007] Fourth, existing cable stripping tools are very difficult to use when encountering resistance during the cable stripping process, and the results are not ideal.

[0008] Fifth, existing wire stripping tools may have unstable precision during the wire stripping process, resulting in incomplete stripping or damage to the underlying cable, affecting the subsequent use and safety of the cable.

[0009] In view of this, the inventor, relying on his professional technical level and rich experience in the long-term research, design and manufacturing of cables, as well as his familiarity with cable products, has specially developed a multi-functional cable stripping tool, which leads to this invention. Utility Model Content

[0010] The purpose of this utility model is to provide a multi-functional cable stripping tool that can quickly switch blades, enabling one set of tools to be compatible with various types of cables, and to perform fast and efficient stripping operations on multi-layer structures such as sheath, insulation, and lead sheath.

[0011] To achieve the above objectives, the solution of this utility model is:

[0012] A multifunctional cable stripper includes a main frame comprising a first fixed end block, a second fixed end block, a movable end block, and a support guide rod. The first and second fixed end blocks are respectively fixed to the two ends of the support guide rod, and the movable end block is slidably assembled onto the support guide rod. A movable handle is provided on the outer side of the first fixed end block, and a first screw extends from the center of the movable handle. The middle section of the first screw is mounted on the first fixed end block with its axial displacement limited by a first stepped bushing. The inner end of the first screw is fixed to the movable end block by a threaded engagement with a screw fixing seat, so that when the first screw rotates, it drives the movable end block to move up and down along the support guide rod. A rotatable double-wheel frame is provided on the inner side of the movable end block, and a first positioning element for positioning the double-wheel frame is provided between the double-wheel frame and the movable end block, forming a double-wheel frame. On the two sets of slides, two first rollers are respectively mounted on the corresponding set of slides in an adjustable positioning manner via their respective first roller shafts; a fixed handle is provided on the outer side of the second fixed end block, and a cutter wheel seat is installed on the inner side of the second fixed end block; a single wheel frame is mounted on the cutter wheel seat in an adjustable lifting manner, and a second positioning component for fixing the single wheel frame is provided between the single wheel frame and the cutter wheel seat; a second roller is mounted on the single wheel frame via a second roller shaft, and the second roller and the two first rollers form a triangular fulcrum for guiding the cable; a cutter holder is also mounted on the cutter wheel seat in an adjustable lifting manner, and a cutter head is mounted on the cutter holder; a second screw is also provided on the cutter holder, and the outer end of the second screw extends to the outer side of the second fixed end block and is connected to an adjusting nut, which drives the cutter holder to rise and fall; a third positioning component is provided between the cutter holder and the cutter wheel seat.

[0013] The movable end block has a guide hole, and the bracket guide rod is inserted into the guide hole.

[0014] The first screw is fixed in the middle section with a first stepped bushing. The stepped groove of the first stepped bushing fits with the hole edge of the first fixed end block, thereby limiting the axial displacement between the first screw and the first fixed end block.

[0015] The screw fixing seat is mounted on the double wheel frame and assembled on the movable end block with the help of the double wheel frame. The inner end of the first screw passes through the first through hole of the movable end block and engages with the thread of the screw fixing seat, so that the first screw drives the movable end block to move up and down along the bracket guide rod.

[0016] An anti-rotation positioning component for positioning the first screw is provided between the first fixed end block and the movable end block. The anti-rotation positioning component is fixed to the inner side of the first fixed end block. The anti-rotation positioning component consists of a pipe clamp and bolts. The base of the pipe clamp is fixed to the inner side of the first fixed end block. The pipe clamp is fitted onto the first screw, and the pipe clamp is fastened to the first screw together by bolts to fix the first screw.

[0017] The two sets of sliding grooves of the double wheel frame are in a figure-eight shape, and the first roller shaft adopts a combination of screw and nut.

[0018] The first roller is a V-shaped roller, and the second roller is a PU bearing roller.

[0019] A first positioning groove is formed on the cutter wheel holder, and the single wheel frame is adjustablely inserted into the first positioning groove. When the adjustment is in place, the single wheel frame is fixed on the cutter wheel holder by means of a second positioning member.

[0020] A second positioning groove is formed on the cutter wheel seat, and the tool holder is adjustablely inserted into the second positioning groove. When the adjustment is in place, the tool holder is fixed on the cutter wheel seat by means of a third positioning member.

[0021] The second and third positioning components are screws. A screw hole communicating with the first or second positioning groove is opened on the side wall of the cutter wheel seat. The screw is assembled in the screw hole, and the inner end of the screw extends into the first or second positioning groove to fix the single wheel frame or cutter holder.

[0022] The tool holder has at least two models, and the cutting head on the tool holder is a single-roll cutter, a double-roll cutter, or a sleeved cutter.

[0023] The side of the tool holder is engraved with scale markings indicating the lifting height.

[0024] With the above-described solution, this invention can adapt to multi-functional stripping operations for cables of different diameters (45mm-150mm) and materials (plastic, lead). In use, rotating the movable handle raises and lowers the first screw, which in turn raises and lowers the first roller on the double-roller frame. The distance between the two first rollers can also be changed by moving the first roller shaft in the groove. Simultaneously, the second roller on the single-roller frame can be adjusted, thereby adjusting the triangular fulcrum position of the two first rollers and the second roller to accommodate stripping cables of different diameters. Furthermore, rotating the double-roller frame rotates the guide direction of the first roller by 90°, and simultaneously rotates the guide direction of the second roller on the single-roller frame by 90°, allowing for rapid and efficient stripping of different cable materials (such as sheath layers, insulation layers, lead sheath layers, and other multi-layered structures). This invention allows for quick switching of the stripper head, enabling one set of tools to adapt to various cable types, improving stripping speed and quality.

[0025] In summary, this utility model of a cable stripper consists of a main frame used in conjunction with a set of blades. The blades can be quickly switched to cut different structures. The blades, along with positioning components, adjustment knobs, and precise scales, improve stripping accuracy. This utility model, through optimized blade structure and design, enhances stripping accuracy and safety, meeting various stripping needs.

[0026] The beneficial technical effects of this utility model compared to existing technologies are as follows: This utility model provides a multi-functional cable stripping tool with both axial and longitudinal cutting capabilities. By changing the tool assembly, it can cut various cable structures such as insulation layers, sheath layers, and lead sheath layers.

[0046] like Figures 1 to 9 As shown, this utility model discloses a multifunctional cable stripping tool. The main frame 10 includes a first fixed end block 11, a second fixed end block 12, a movable end block 13, and a support guide rod 14.

[0047] The first fixed end block 11 and the second fixed end block 12 are respectively fixed to the two ends of the support guide rod 14, and the movable end block 13 is assembled on the support guide rod 14 in a way that allows it to slide up and down. Specifically, a guide hole 132 can be opened on the movable end block 13, and the support guide rod 14 is inserted into the guide hole 132. A bearing can be installed in the guide hole 132 to make the operation smoother. The movable end block 13 can slide up and down under the action of external force by the support guide rod 14.

[0048] A movable handle 20 is provided on the outer side of the first fixed end block 11. A first screw 21 extends from the center of the movable handle 20. The middle section of the first screw 21 is mounted on the first fixed end block 11 with its axial displacement limited by a first stepped bushing 22, allowing the first screw 21 to rotate on the first fixed end block 11 without axial movement relative to it. Specifically, the middle section of the first screw 21 is fixed with the first stepped bushing 22, and the stepped groove of the first stepped bushing 22 engages with the edge of the hole in the first fixed end block 11, thus limiting the axial displacement between the first screw 21 and the first fixed end block 11. The inner end of the first screw 21 is fixed to the movable end block 13 by a threaded engagement with the screw fixing seat 23. When the movable handle 20 is rotated, the first screw 21 rotates accordingly, which can drive the movable end block 13 to move up and down along the bracket guide rod 14 to meet the needs of stripping cables of different sizes. To ensure that the movable handle 20 and the first screw 21 can be fixed relative to the first fixed end block 11 after adjustment, an anti-rotation positioning member 24 for positioning the first screw 21 is further provided between the first fixed end block 11 and the movable end block 13. The anti-rotation positioning member 24 is fixed to the inner side of the first fixed end block 11. The anti-rotation positioning member 24 is specifically composed of a pipe clamp 241 and a bolt 242. The base of the pipe clamp 241 is fixed to the inner side of the first fixed end block 11, and the pipe clamp 241 is fitted onto the first screw 21. After the movable handle 20 is rotated to adjust and the first roller 33 and the second roller 63 clamp the cable, the pipe clamp 241 is tightened to hold the first screw 21 (fastened together) by rotating the bolt 242, thereby achieving the effect of fixing the first screw 21.

[0049] A rotatable double-wheel frame 30 is provided on the inner side of the movable end block 13. A first positioning element 31 for positioning the double-wheel frame 30 is provided between the double-wheel frame 30 and the movable end block 12. The first positioning element 31 can be a screw, which is tightened to position the double-wheel frame 30 on the movable end block 12. Specifically, as shown in the figure, the screw fixing seat 23 is mounted on the double-wheel frame 30. The screw fixing seat 23 is assembled on the movable end block 13 with the help of the double-wheel frame 30. The inner end of the first screw 21 passes through the first through hole 131 of the movable end block 13 and engages with the threaded connection of the screw fixing seat 23. Thus, when the first screw 21 is rotated, the movable end block 13 is moved up and down along the bracket guide rod 14 through the screw fixing seat 23 and the double-wheel frame 30. In the figure, the first positioning element 31 can position the screw fixing seat 23 and the double-wheel frame 30 together on the movable end block 12. The double-wheel frame 30 also forms two sets of sliding grooves 34. The two first rollers 32 are respectively mounted on the corresponding set of sliding grooves 34 in an adjustable positioning manner through their respective first roller shafts 33. Specifically, the sliding grooves 34 are designed in a figure-eight shape. The first roller shafts 33 adopt a combination of screws and nuts. By moving the first roller shafts 33 in the sliding grooves 34, the position of the first roller shafts 33 on the sliding grooves 34 of the double-wheel frame 30 is changed, thereby changing the position and spacing of the two first rollers 32. This allows adjustment of the triangular fulcrum formed between the first rollers 32 and the second rollers 63 (described later), which can better adapt to cables with different outer diameters.

[0050] A fixed handle 40 is provided on the outer side of the second fixed end block 12, and a cutter wheel seat 50 is installed on the inner side of the second fixed end block 12. A single wheel frame 60 is mounted on the cutter wheel seat 50 in an adjustable lifting manner. A second positioning member 61 for fixing the single wheel frame 60 is provided between the single wheel frame 60 and the cutter wheel seat 50. A second roller 63 is mounted on the single wheel frame 60 through a second roller shaft 62. The second roller 63 and the two first rollers 33 form a triangular fulcrum for guiding the cable. In order to better guide the cable, the first roller 33 is a V-shaped roller, and the second roller 63 is a PU bearing roller. The cutter wheel holder 50 is also equipped with an adjustable cutter holder 70. A cutter head 71 is mounted on the cutter holder 70, and a second screw 72 is also provided on the cutter holder 70. The outer end of the second screw 72 extends to the outside of the second fixed end block 12 and connects to an adjusting nut 73. The adjusting nut 73 drives the second screw 72 and the cutter holder 70 to move up and down, thereby adjusting the cutting depth. A third positioning element 74 is provided between the cutter holder 70 and the cutter wheel holder 50. The side of the cutter holder 70 may be engraved with scale markings 75 to indicate the lifting height. The scale on the cutter holder 70 allows for more precise control of the cutting depth. The third positioning element 74 (knurled high-head screw) on the side of the cutter wheel holder 50 can fix the cutter holder 70 after adjustment, preventing the cutter from shaking during cutting and causing uneven cutting.

[0051] Specifically, the cutter wheel holder 50 has a first positioning groove 51 and a second positioning groove 52. A screw hole communicating with either the first or second positioning groove 51 is provided on the side wall of the cutter wheel holder 50. The single wheel frame 60 is adjustablely inserted into the first positioning groove 51, and the tool holder 70 is adjustablely inserted into the second positioning groove 52. The second positioning element 61 and the third positioning element 74 are screws, assembled in screw holes, with the inner end of the screw extending into the first or second positioning groove 51 or 52. When the single wheel frame 60 and the tool holder 70 are adjusted to their positions, the second positioning element 61 and the third positioning element 74 respectively fix the single wheel frame 60 and the tool holder 70 to the cutter wheel holder 50. The tool holder 70 has at least two models, and the cutter head 71 on the tool holder 70 is a single hobbing cutter. Figure 2 ), double hobbing cutter ( Figure 8 ) or sheathed knife ( Figure 9 Among them, the single roller cutter is mainly used for cutting the lead sheath layer with high hardness, the sheath cutter can spin cut the cable insulation layer and sheath layer, and the double roller cutter (double blade) can be used to roll the lead sheath. After rolling, two axial cuts are formed on the surface. The lead sheath is peeled off along the axial cuts with needle-nose pliers or other tools.

[0052] In practical use, the cable is placed between the first roller 33 and the second roller 63. When pulling the cable, it is guided by the first roller 33 and the second roller 63. During the pulling process, the cable is cut by the cutter head 71 on the cutter holder 70, thus achieving stripping. This invention can also achieve the transformation from longitudinal cutting to circular cutting by rotating the double-wheel frame 30, the cutter holder 70, and the single-wheel frame 60 by 90°.

[0053] This utility model features multiple blade holders 70 with different blade heads 71, integrating various wire stripping and cutting functions, significantly improving the efficiency and quality of cable manufacturing. The blade design is reasonable, adaptable to cables of different diameters and materials, reducing the number of tools required and improving portability. Simultaneously, this utility model emphasizes operational safety and convenience, reducing operational difficulty and ensuring safety through optimized blade structure and operation methods. This utility model designs a multi-functional wire stripping blade adaptable to different cable diameters (45mm-150mm) and materials (plastic, lead), improving stripping speed and quality. The cutting blade of this utility model is easy to disassemble and replace. This utility model's blade can be equipped with multiple blade heads 71, such as lead stripping rollers and sheathing blades, allowing simultaneous stripping of multiple cable structures, including lead sheaths and sheaths, by changing the blade heads 71. The blade design considers human strength characteristics, utilizing both hands simultaneously for cutting, avoiding uneven force and excessive resistance during cutting, thus improving cutting efficiency. The tool holder 70 of this utility model has graduations on its side, which can precisely control the cutting depth and improve accuracy.

[0054] The embodiments described above are only for illustrating the technical ideas and features of this utility model. Their purpose is to enable those skilled in the art to understand the content of this utility model and implement it accordingly, but they do not limit the patent scope of this utility model.
