Description

Technical Field

[0001] This utility model relates to the technical field of cable cutting devices for electrical engineering, and in particular to a cable cutting device for electrical engineering. Background Technology

[0002] In today's electrical engineering field, cables, as a crucial carrier for power transmission and signal transmission, have extremely wide applications. From large-scale urban building power supply systems to complex industrial automated production lines, and even the internal connections of precision electronic equipment, cables are ubiquitous. With the continuous expansion of electrical engineering projects, the demand for cables has increased dramatically, and the requirements for cable specifications and lengths vary across different projects. This makes precise cable cutting a fundamental and crucial task in the engineering implementation process.

[0003] Traditional cable cutting methods have many problems. Early manual cutting tools, such as ordinary cable cutters, relied entirely on manual operation, which was not only labor-intensive but also extremely inefficient. Operators were prone to fatigue after long hours of work, resulting in significant errors in the cut cable length, which failed to meet the precision requirements of modern engineering. For some thicker and harder cables, manual tools were even more inadequate, often requiring a lot of time and effort, and the cut surface might be uneven, affecting the quality of subsequent cable connections and electrical performance.

[0004] While some simple automated cable cutting devices improve efficiency to a certain extent, they still have serious drawbacks. Their cable conveying mechanisms are poorly designed, leading to cable slippage and jamming during transport. This not only affects the accuracy of the cutting length but can also damage the cable. Furthermore, the cutting mechanisms of these devices lack stability and durability; frequent use causes wear and tear on the cutting components, requiring frequent replacements. This increases equipment maintenance costs and construction downtime, severely impacting project progress, further reducing work efficiency, and creating chaos on the construction site. Therefore, a cable cutting device for electrical engineering is proposed to address these problems. Utility Model Content

[0024] 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.

[0025] Example 1

[0026] The cable conveying mechanism is poorly designed, leading to cable slippage and jamming during transport. This not only affects the accuracy of the cut length but may also damage the cable. Furthermore, the cutting mechanism of these devices lacks stability and durability; frequent use causes wear and damage to the cutting components, requiring frequent replacements. This increases equipment maintenance costs and construction downtime, severely impacting project progress. This embodiment provides a cable cutting device for electrical engineering. Please refer to... Figures 1-4 An embodiment provides a cable cutting device for electrical engineering, including a device body 1. The device body 1 is provided with a connecting mechanism 2, which includes a feeding assembly 21 disposed on the right side of the device body 1, a feeding assembly 22 disposed on the middle side of the device body 1, and a cutting assembly 23 disposed on the left side of the device body 1. The cutting assembly 23 includes a limiting plate 231 fixedly connected to the inner wall of the left side of the device body 1. A sliding plate 232 is slidably connected to the inner wall of the limiting plate 231. A connecting spring 233 is fixedly connected to one end of the inner side of the sliding plate 232. A mounting plate 234 is fixedly connected to the inner side of the connecting spring 233. A cable cutting device is fixedly mounted on the inner side of the mounting plate 234. A drive motor 235 is driven by a drive gear 236 at its output end. A toothed ring cutter 237 meshes with the inner side of the drive gear 236. A fixed ring frame 238 is rotatably connected to the outer wall of the toothed ring cutter 237. A fixed frame 239 is fixedly connected to the inner wall of the middle section of the device body 1. A material conveying rod 2310 is rotatably connected to the inner side of the fixed frame 239. A wire guide wheel 2311 is fixedly connected to the outer wall of the material conveying rod 2310. A fixed block 2312 is fixedly connected to the top of the inner wall of the device body 1. A limit spring 2313 is fixedly connected to the bottom of the fixed block 2312. A lifting wheel 2314 is rotatably connected to the inner side of the limit spring 2313.

[0027] In this embodiment, the cutting component 23 is the key part for achieving the final cutting of the cable; the limiting plate 231, which is fixedly connected to the inner wall of the left side of the device body 1, is slidably connected to the sliding plate 232, and the inner side of the connecting spring 233, which is fixedly connected to one end of the sliding plate 232, is fixedly connected to the mounting plate 234; when the cable is transported to the cutting position according to the set length, the drive motor 235 fixedly installed on the inner side of the mounting plate 234 starts to work. The drive motor selected here is a permanent magnet synchronous drive motor, such as a 155 permanent magnet synchronous drive motor, whose working voltage range is 96-4. With a voltage of 50V, a torque range of 100-220Nm, a power range of 45-135KW, and a maximum operating speed of 17000rpm, this motor provides powerful and stable power output to meet the needs of fast and efficient cable cutting. The output of the drive motor 235 is connected to the drive gear 236, which then rotates at high speed. Because the inner side of the drive gear 236 meshes with the toothed ring cutter 237, the toothed ring cutter 237 begins to perform circular motion under the drive of the drive gear 236. A fixed ring frame is rotatably connected to the outer wall of the toothed ring cutter 237. 238, and the fixed ring frame 238 is fixedly installed on the mounting plate 234. This structural design ensures the stability of the toothed ring cutting ring 237 during rotation, enabling it to reliably cut the cable. Simultaneously, the material conveying rod 2310, rotatably connected to the inner side of the fixed frame 239 fixedly connected to the inner wall of the middle section of the device body 1, and the wire guide wheel 2311 fixedly connected to its outer wall play a crucial role in guiding the cable, ensuring that the cable remains straight during cutting and preventing the cutting quality from being affected by cable bending. The top of the inner wall of the device body 1 is fixedly connected to... The lifting wheel 2314, which is rotatably connected to the inner side of the limiting spring 2313 fixedly connected to the bottom of the fixed block 2312, applies a certain pressure to the cable during the cable cutting process. It works in conjunction with the wire guide wheel 2311 to ensure that the cable does not shake or shift during cutting, which greatly improves the cutting accuracy and quality. After the cable cutting is completed, the drive motor 235 stops working, and the connecting spring 233 pushes the sliding plate 232 and the mounting plate 234 to reset by its own elastic force, so that the cutting component 23 returns to the initial state and waits for the next cutting task.

[0028] Furthermore, the limiting plate 231 is slidably connected to the inner wall of the device body 1; the fixed ring frame 238 is fixedly installed on the mounting plate 234, and the drive motor 235, drive gear 236, gear ring cutter 237 and fixed ring frame 238 are symmetrically arranged on the inner side of the limiting plate 231 and the mounting plate 234.

[0029] Furthermore, the material transfer rod 2310, which is rotatably connected to the inner side of the fixed frame 239 fixedly connected to the inner wall of the middle section of the device body 1, and the wire guide wheel 2311 fixedly connected to its outer wall, plays an important role in guiding the cable, ensuring that the cable remains straight during the cutting process and avoiding the impact of cable bending on the cutting quality. The lifting wheel 2314, which is rotatably connected to the inner side of the fixed block 2312 fixedly connected to the top of the inner wall of the device body 1 and the limiting spring 2313 fixedly connected to the bottom, applies a certain pressure to the cable during the cable cutting process. It works in conjunction with the wire guide wheel 2311 to ensure that the cable does not shake or shift during the cutting process, which greatly improves the cutting accuracy and quality.

[0030] Example 2

[0031] Based on Embodiment 1, the feeding assembly 21 includes a fixed rod 211 fixedly connected to the inner wall of the device body 1, a winding wheel 212 rotatably connected to the inner side of the fixed rod 211, a fixed frame 213 fixedly connected to the inner side of the device body 1, a material transfer rod 214 rotatably connected to the inner side of the fixed frame 213, and a wire guide wheel 215 fixedly connected to the outer wall of the material transfer rod 214; the material transfer assembly 22 includes a feed motor 221 fixedly installed on the inner wall of the middle section of the device body 1, a rotating shaft 222 fixedly connected to the bottom output end of the feed motor 221, a feed wheel 223 fixedly connected to the outer wall of the rotating shaft 222, a material transfer wheel 224 frictionally and rollingly connected to the inner side of the feed wheel 223, and a wire baffle 225 fixedly connected to the top of the upper section of the middle section of the device body 1.

[0032] In this embodiment, the unloading assembly 21 mainly undertakes the task of orderly cable release; the inner side of the fixed rod 211, which is fixedly connected to the inner wall of the device body 1, is rotatably connected to the winding wheel 212, and the cable is tightly wound around the outer wall of the winding wheel 212; when the device starts working, the winding wheel 212 can rotate freely according to the cable conveying requirements and smoothly release the cable; the fixed frame 213, which is fixedly connected to the inner side of the device body 1, has a conveying rod 214 rotatably connected to its inner side, and a cable guide wheel 215 is fixedly installed on the outer wall; after the cable is released from the winding wheel 212, it will roll through the cable guide wheel. The top outer wall of wheel 215; the cable guide wheel 215 plays a key role in guiding the cable conveying direction and reducing friction. Through its own rolling motion, it allows the cable to be smoothly and steadily conveyed to the material transfer assembly 22, preventing jamming or deviation during the conveying process. The material transfer assembly 22 is responsible for precisely conveying the cable according to a preset speed and length. The core power source of this assembly is the feed motor 221, which is fixedly installed on the inner wall of the middle section of the device body 1. A high-precision servo motor, such as OMRON's AC..., is selected here. The R88M-1□ / R88D-1SN□-ECT model in the 1S series servo system provides stable and precise speed output to meet the requirements of different cable conveying speeds. The feed motor 221 has a rotating shaft 222 fixedly connected to its bottom output end, which drives the feed wheel 223 to rotate. The inner side of the feed wheel 223 is connected to the transfer wheel 224 via frictional rolling. When the feed motor 221 starts, the rotating shaft 222 rotates at high speed, driving the feed wheel 223 to rotate, which in turn drives the transfer wheel 224 to rotate synchronously by friction. The transfer wheel 224 is perpendicular to the cable... The cable is pushed towards the cutting component 23 by strong friction. The baffle plate 225, which is fixedly connected to the top of the upper section of the middle section of the device body 1, is located directly above the feed wheel 224. Its function is to abut against the cable driven by the feed wheel 224 to prevent the cable from deviating or jumping out of the feed wheel 224 due to external interference during the conveying process, thus ensuring the stability and accuracy of the cable conveying process. By precisely controlling the speed and rotation time of the feed motor 221, the conveying length of the cable can be precisely controlled to meet the diverse needs of different projects for cable length.

[0033] Furthermore, the outer wall of the take-up reel 212 is wound with a cable, and the cable is rolled on the top outer wall of the wire guide reel 215; the feed reel 224 is rotatably connected to the inside of the feed motor 221, and the wire stop plate 225 is set directly above the feed reel 224 to abut against the cable driven by the feed reel 224.

[0034] Furthermore, a fixed frame 213 is fixedly connected to the inner side of the device body 1, and a guide wheel 215 is fixedly installed on the outer wall of the conveying rod 214 rotatably connected to the inner side of the frame 213. After the cable is released from the take-up wheel 212, it will roll through the top outer wall of the guide wheel 215. The guide wheel 215 plays a key role in guiding the direction of cable conveying and reducing friction. Through its own rolling, it allows the cable to be conveyed smoothly and steadily to the conveying assembly 22, avoiding jamming or deviation of the cable during the conveying process. The conveying assembly 22 is responsible for accurately conveying the cable according to the preset speed and length.

[0035] Working principle: The unloading assembly 21 is mainly responsible for the orderly release of the cable; the inner side of the fixed rod 211, which is fixedly connected to the inner wall of the device body 1, is rotatably connected to the winding wheel 212, and the cable is tightly wound on the outer wall of the winding wheel 212; when the device starts to work, the winding wheel 212 can rotate freely according to the cable conveying requirements and smoothly release the cable; the fixed frame 213, which is fixedly connected to the inner side of the device body 1, has a conveying rod 214 rotatably connected to its inner side, and a wire guide wheel 215 is fixedly installed on the outer wall; after the cable is released from the winding wheel 212, it will roll through the top outer wall of the wire guide wheel 215; the wire guide wheel 215 plays a key role in guiding the direction of cable conveying and reducing friction. Through its own rolling, it allows the cable to be smoothly and steadily conveyed to the conveying assembly 22, avoiding jamming or deviation of the cable during the conveying process;

[0036] The material conveying assembly 22 is responsible for precisely conveying the cable according to a preset speed and length. The core power source of this assembly is the feed motor 221, which is fixedly installed on the inner wall of the middle section of the device body 1. A high-precision servo motor is selected here, such as the R88M-1□ / R88D-1SN□-ECT model from OMRON's AC servo system 1S series, which can provide stable and precise speed output to meet the requirements of different cable conveying speeds. The rotating shaft 222, fixedly connected to the bottom output end of the feed motor 221, drives the feed wheel 223 to rotate. The inner side of the feed wheel 223 is connected to the material conveying wheel 224 via frictional rolling. When the feed motor 221 starts, the rotating shaft 222... The high-speed rotation drives the feed wheel 223 to rotate, which in turn drives the transfer wheel 224 to rotate synchronously by friction. The transfer wheel 224 is in direct contact with the cable, and the strong friction pushes the cable toward the cutting component 23. The baffle plate 225, which is fixedly connected to the top of the upper section of the middle section of the device body 1, is located directly above the transfer wheel 224. Its function is to abut against the cable driven by the transfer wheel 224 to prevent the cable from deviating or jumping out of the transfer wheel 224 due to external interference during the conveying process, thus ensuring the stability and accuracy of the cable conveying process. By precisely controlling the speed and rotation time of the feed motor 221, the conveying length of the cable can be precisely controlled to meet the diverse needs of different projects for cable length.

[0037] The cutting component 23 is the key part for achieving the final cable cutting; the limiting plate 231, which is fixedly connected to the inner wall of the left side of the device body 1, is slidably connected to the sliding plate 232, and the inner side of the connecting spring 233, which is fixedly connected to one end of the sliding plate 232, is fixedly connected to the mounting plate 234; when the cable is delivered to the cutting position according to the set length, the drive motor 235 fixedly installed on the inner side of the mounting plate 234 starts to work. The drive motor selected here is a permanent magnet synchronous drive motor, such as a 155 permanent magnet synchronous drive motor, whose working voltage range is 96-450V. With a torque range of 100-220 Nm, a power range of 45-135 KW, and a maximum operating speed of 17000 rpm, it can provide powerful and stable power output to meet the needs of fast and efficient cable cutting. The output end of the drive motor 235 is connected to the drive gear 236, which begins to rotate at high speed. Due to the meshing between the inner side of the drive gear 236 and the toothed ring cutter 237, the toothed ring cutter 237 begins to perform circular motion under the drive of the drive gear 236. A fixed ring frame 238 is rotatably connected to the outer wall of the toothed ring cutter 237. Furthermore, the fixed ring frame 238 is fixedly installed on the mounting plate 234. This structural design ensures the stability of the toothed ring cutting ring 237 during rotation, enabling it to reliably cut cables. Simultaneously, the material conveying rod 2310, rotatably connected to the inner side of the fixed frame 239 fixedly connected to the inner wall of the middle section of the device body 1, and the wire guide wheel 2311 fixedly connected to its outer wall play a crucial role in guiding the cable, ensuring that the cable remains straight during cutting and preventing cable bending from affecting the cutting quality. The fixed ring frame 238 is fixedly connected to the top of the inner wall of the device body 1. The lifting wheel 2314, which is rotatably connected to the inner side of the limiting spring 2313 fixed to the bottom of the fixed block 2312, applies a certain pressure to the cable during the cable cutting process. It works in conjunction with the wire guide wheel 2311 to ensure that the cable does not shake or shift during cutting, which greatly improves the cutting accuracy and quality. After the cable cutting is completed, the drive motor 235 stops working, and the connecting spring 233 pushes the sliding plate 232 and the mounting plate 234 to reset by its own elastic force, so that the cutting component 23 returns to the initial state and waits for the next cutting task.

[0038] During the entire operation of the device, the feeding component 21 continuously and stably releases the cable, the conveying component 22 precisely controls the cable conveying length and speed, and the cutting component 23 efficiently and accurately completes the cable cutting work. The components work closely together and coordinate to realize the automation and precision of cable cutting, fully meeting the high quality and high efficiency requirements of modern electrical engineering for cable cutting.
