Detailed Implementation

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0025] Currently, most wire strippers in related technologies can only strip wires from the cable end. Because they are difficult to install in the middle of the cable, they cannot perform stripping operations in the middle. While a few wire strippers can be installed in the middle of the cable and can perform electric stripping, the clamping method in the middle of the cable is unstable, resulting in low safety and low efficiency. This application solves the above problems.

[0026] The following is combined with Figures 1 to 4 The following describes embodiments of the present invention.

[0027] This utility model provides a cable stripper, comprising: two clamping discs 1, an actuating disc 4, a cutting tool 16, and a driving device 5. The two clamping discs 1 are arranged sequentially along a first axis and are rotatably connected to each other around the first axis. Each clamping disc 1 has a slot 6 extending from its edge inward to the first axis. The end of the slot 6 has an arc-shaped inner wall. Driving the clamping discs 1 to rotate relative to each other allows the two clamping discs 1 to reach two relative positions. The first relative position is when the two slots 6 completely overlap along the direction of the first axis; the second relative position is when, relative to the first relative position, the two slots 1 are partially overlapping. The relative rotation angle of the clamping disk 1 is 180 degrees; the slot 6 on the clamping disk 1 in the first relative position is used for the cable to enter into the slot 6; the clamping disk 1 in the second relative position is used to clamp the cable; the actuating disk 4 is rotatably connected to one side of a clamping disk 1 around the first axis; the actuating disk 4 also has a slot 6 extending from the edge inward to the first axis; the cutting tool 16 is fixedly set on the side of the actuating disk 4 away from the clamping disk 1, and the cutting edge 11 of the cutting tool 16 is used to embed into the outer sheath of the cable; the driving device 5 is fixedly set on any one of the clamping disks 1 and is used to drive the actuating disk 4 to rotate around the first axis.

[0028] Compared to existing wire strippers, the cable stripper provided by this utility model can firmly clamp the cable in the middle position, which not only ensures the accuracy of the operation, but also significantly enhances the stability of the stripping and the safety of the operation.

[0029] The process is as follows: Rotate the clamping disc 1 and the actuating disc 4 so that the slots 6 on the two clamping discs and the actuating disc 4 completely overlap along the direction of the first axis. Then, place the middle part of the cable from the opening of the slot 6 at the bottom of the slot 6. Then, manually rotate one of the clamping discs 1 to rotate it 180°. At this time, the two clamping discs 1 are clamped on the cable, thereby achieving the purpose of rotatably installing the actuating disc 4 on the cable. After installation, start the drive device 5. The power source of the drive device 5 is usually a rotary motor. The rotary motor drives the actuating disc 4 to drive the cutter 16 to rotate. When the cutter 16 rotates, it can cut, slice or scrape off the outer sheath of the cable.

[0030] In some embodiments, the card slot 6 is U-shaped. It can be understood that the card slot 6 is generally U-shaped, and the bottom of the card slot 6 is a semi-circular arc surface.

[0031] In this embodiment, the U-shaped slot 6 facilitates the cable entering to the bottom of the slot 6.

[0032] In some embodiments, both the clamping disc 1 and the actuating disc 4 include a disc body and U-shaped chucks 10 of various specifications. The disc body has a groove extending from the edge inward. The U-shaped chucks 10 can be detachably inserted into the groove. The closed end of the U-shaped chucks 10 is located inside the groove. A slot 6 is formed inside the U-shaped chucks 10. In use, the two clamping discs 1 are equipped with U-shaped chucks 10 of the same specification. U-shaped chucks 10 of different specifications form slots 6 of different sizes.

[0033] This embodiment greatly expands the application scenarios and flexibility of cable strippers. Specifically, the various specifications of the U-shaped clamps 10 are designed to accommodate the wide variety of cables with different diameters available on the market.

[0034] The U-shaped clamp 10 is preferably made of insulating material.

[0035] The U-shaped chuck 10 is detachably connected to the clamping plate 1 and the actuating plate 4 by screws or bolts.

[0036] In some embodiments, the surface material of the slot 6 is selected as an anti-slip and shock-absorbing composite material, preferably a high-performance anti-slip and shock-absorbing composite material. That is, the material of the U-shaped chuck 10 can be selected as an anti-slip and shock-absorbing composite material, preferably a high-performance anti-slip and shock-absorbing composite material.

[0037] This embodiment uses an anti-slip and shock-absorbing composite material to enhance the clamping stability of the cable. This material has a high coefficient of friction and excellent damping characteristics, which not only significantly enhances the static friction between the cable and the slot 6, but also effectively absorbs the mechanical vibration generated during the stripping process, ensuring smooth operation.

[0038] In some embodiments, the surface of the slot 6 that contacts the cable is constructed with a serrated structure. Preferably, it has an irregular serrated structure.

[0039] This embodiment significantly increases the contact area between the cable and the slot 6 by utilizing an irregular surface, achieving a more uniform stress distribution through multi-point contact. The serrated structure can slightly embed into the cable sheath under appropriate pressure, forming a mechanical interlocking effect and providing additional axial restraint.

[0040] In some embodiments, the disc body includes two end split discs 7 and a middle split disc 8. One end split disc 7, the middle split disc 8 and the other end split disc 7 are detachably connected in sequence along a first axis. Two adjacent disc bodies are rotatably connected by a rotating cylinder 2. One side of the rotating cylinder 2 has a notch. Both ends of the rotating cylinder 2 in the axial direction are constructed with limiting plates extending radially from the end of the rotating cylinder 2 away from the axis of the rotating cylinder 2. The limiting plates have a ring-shaped structure. The notch of the limiting plate is directly opposite the notch of the rotating cylinder 2. The sides of any two adjacent end split discs 7 that are close to each other are in contact and are both sleeved on the same rotating cylinder 2. The limiting plates are in contact with the sides of the split discs sleeved on the rotating cylinder 2 and restrict axial movement.

[0041] This embodiment enables the clamping disk 1 and the actuating disk 4 at the edge to rotate relative to the clamping disk 1 at the center, while facilitating the placement of the middle part of the cable into the slot 6.

[0042] In some embodiments, the U-shaped clamp 10 is installed inside the middle section disc 8.

[0043] In some embodiments, the cutting tool 16 includes a handle 12 and a cutting head 13. The handle 12 is detachably mounted on the actuating disk 4, and the cutting head 13 is fixedly disposed at the end of the handle 12. The included angle between the handle 12 and the first axis is 45° to 85°, and the position of the cutting head 13 relative to the cable is adjustable.

[0044] Specifically, an inclined tool holder 3 is installed on the actuation plate 4, and the tool holder 12 is installed on the tool holder 3. In this embodiment, the purpose of the inclined tool holder 12 is to generate an axial feed force when the wire stripper is performing circumferential cutting. This feed force is the reaction force of the cable to the tool 16, which enables the entire cable stripper to move axially on the cable. That is, when the wire stripper is stripping the wire, the travel trajectory of the blade 11 of the tool 16 is a spiral trajectory. The synergistic effect of this dual motion mechanism ensures that the stripping process not only ensures the flatness and smoothness of the cutting surface, but also accurately controls the stripping length, effectively improving the accuracy and efficiency of the stripping operation.

[0045] When using the cable stripper, clamp it onto the cable, hold the cable stripper by hand, and then start the drive device 5 to drive the actuating disk 4 to rotate. The purpose of holding the cable stripper by hand is to prevent the cable stripper from rotating circumferentially under the reaction force of the cable, so that the cable stripper can only move axially on the cable stripper. Of course, in some cases, when the reaction force given by the cable is insufficient to drive the cable stripper to move axially, the cable stripper can be manually assisted to move.

[0046] In some embodiments, to facilitate the cable stripper to move only along the axial direction, the serrated structure can be configured as regular serrations extending along the axial direction. This can prevent the stripper from rotating circumferentially during operation. After the axially extending serrations are embedded in the cable sheath, they can act as an axial track so that the stripper can move only axially.

[0047] To achieve adjustable position of the blade 13 relative to the cable, this embodiment also includes a knob 15 and a screw 14 located at the tail of the handle. One end of the knob 15 has a threaded hole that matches the screw 14. A spring can be installed on the screw 14, with its two ends abutting against one end of the knob 15 and the tail of the handle, respectively. The spring is always in a compressed state. The tool holder 3 has a mounting hole. During installation, one end of the screw 14 is passed through the mounting hole, and the knob 15 is threadedly connected to the end of the screw 14, compressing the spring. The depth of the blade embedded in the cable sheath is adjusted by adjusting the length of the threaded connection between the knob 15 and the screw 14.

[0048] After installing the wire stripper, before starting it, manually adjust the relative position of the blade 11 of the cutter head 13 and the cable so that the blade 11 is embedded in the cable sheath, and then start the drive device 5.

[0049] In some embodiments, the blade 13 is an arc-shaped blade, the thickness of which gradually decreases from the root to the cutting edge.

[0050] In this embodiment, the blade adopts a scraper design, which allows the blade to cut into the cable sheath more smoothly during rotation, enabling precise scraping operations. The cutting edge is designed as an arc-shaped cutting edge with a radius R = 2.5mm. Its cutting surface is an involute curve, forming an optimal cutting angle of 15°-20° with the cable sheath.

[0051] The cutting head 13 of this invention is precision-machined from high-strength alloy steel, and its ingenious arc-shaped cutting edge design achieves a progressive cutting mechanism, enabling smooth and gradual cutting of the cable sheath. This effectively avoids the cable deformation problem caused by the sudden cutting of traditional cutting tools 16. The involute curved surface design of the cutting edge ensures that the cutting force is evenly distributed at the cutting edge, significantly reducing local stress concentration and ensuring the stability of the cutting process. Furthermore, the unique wedge-shaped structure naturally forms an efficient chip removal channel, with a chip groove angle designed at 45°, which can promptly remove chips generated during the cutting process, preventing chip accumulation from adversely affecting the cutting quality. The combination of high-strength alloy material and optimized structural design significantly improves the overall durability and service life of the cutting tool 16. In actual operation, as the actuating disc 4 rotates smoothly, the scraper gradually penetrates the cable sheath at a controllable speed. Through precise control of the cutting angle and force, uniform stripping of the cable sheath is achieved, thus ensuring the efficiency and reliability of the entire stripping process.

[0052] In some embodiments, a driven gear 17 is fixedly provided on the outer side of the middle part of the actuating disk 4, the driven gear 17 is a ring-shaped gear, the driving device 5 includes a rotary motor and a driving gear, the rotary motor is connected to the driving gear, there are two or more driving gears, and the driving gear and the driven gear 17 mesh.

[0053] This embodiment achieves the purpose of electric wire stripping. In some examples, the driving gear includes a medium gear and two small gears. The medium gear is directly connected to the rotary motor, which drives the medium gear to rotate. One side of the two small gears meshes with the medium gear, and the other side meshes with the driven gear 17. This avoids the risk of failure of the driving gear and driven gear 17 meshing due to the driven gear 17 being a missing ring gear, and improves the stability of the operation.

[0054] In some embodiments, handles 9 are provided on the sides of both clamping discs 1 to facilitate hand-held rotation of the clamping discs 1, hand-held clamping discs 1 to limit the circumferential movement of the entire wire stripper during use, and hand-held clamping discs 1 to assist the axial movement of the entire wire stripper.

[0055] This utility model uses specific examples to illustrate its principles and implementation methods. The above description of the embodiments is only for the purpose of helping to understand the method and core idea of ​​this utility model. At the same time, for those skilled in the art, there will be changes in the specific implementation methods and application scope based on the idea of ​​this utility model. In summary, the content of this specification should not be construed as a limitation of this utility model.
