Description

Technical Field

[0001] This utility model relates to the field of cable cutting technology, specifically to a cable cutting machine. Background Technology

[0002] During the cable cutting process, the following steps are followed: first, the cable insulation layer is cut, and then the cable conductor is cut. When cutting the cable insulation layer, the cutting method should be followed: first horizontal cuts, then vertical cuts.

[0003] In existing technologies, insulation layer cutting relies on mechanical pressure to achieve separation. The hard contact between the tool and the insulation layer not only requires the continuous application of a large force, but also makes it easy for the tool to penetrate the insulation layer and cut the conductor due to excessive pressure. This can lead to scratches on the surface of the conductor, which may cause safety hazards such as decreased conductivity and localized heating. Utility Model Content

[0004] This utility model proposes a cable cutting machine that solves the problem in related technologies where excessive pressure from the cutting tool penetrates the insulation layer and cuts the conductor, resulting in easy scratches on the conductor surface.

[0005] The technical solution of this utility model is as follows: A cable cutting machine includes a base, a guide rail drive mechanism is provided on the base, a rotating support is installed on the guide rail drive mechanism, a cutting mechanism is provided on the rotating support for cutting the insulation layer and conductor of the cable respectively, the cutting machine is also provided with a clamping mechanism to clamp the cable, a rotating mechanism for driving the rotating support to rotate is provided on the rotating support, the cutting mechanism includes a mounting bracket, a rotating motor is fixedly connected to the mounting bracket, an electric telescopic rod is fixedly connected to the output end of the rotating motor, a cutting blade is fixedly connected to the output end of the electric telescopic rod, a heating plate is fixedly connected to the end of the electric telescopic rod near the cutting blade, and a guide groove is opened in the heating plate.

[0006] Preferably, the cutting mechanism further includes hydraulic rods, two of which are symmetrically installed. The hydraulic rods are fixedly connected to the mounting bracket, and the output end of the hydraulic rod is fixedly connected to a shearing blade.

[0007] Preferably, a scraper is fixedly connected to the end of the heating plate away from the electric telescopic rod, and two scrapers are provided and installed symmetrically.

[0008] Preferably, a driven gear is rotatably mounted on the rotating support, the mounting bracket is fixedly connected to the surface of the driven gear, and a driving gear is rotatably mounted on the rotating support, the driving gear and the driven gear meshing with each other.

[0009] Preferably, the rotating mechanism includes a servo motor, which is fixedly connected to one side of the rotating support, and the output end of the servo motor is fixedly connected to the drive gear.

[0010] Preferably, the clamping mechanisms are respectively disposed on the left and right sides of the rotating support, one of the clamping mechanisms is fixedly connected to the surface of the base, and the other clamping mechanism is fixedly connected to the side of the rotating support near the rotating mechanism.

[0011] Preferably, the clamping mechanism includes a slide rail, in which a screw is rotatably mounted. The screw has two sections of threads with opposite directions of rotation. A lifting slide is slidably connected to the two sections of threads with opposite directions of rotation. A stepper motor is fixedly connected to the end of the slide rail. The output end of the stepper motor is fixedly connected to the screw. A V-shaped clamping block is provided on the lifting slide.

[0012] The beneficial effects of this utility model are as follows:

[0013] In this invention, the V-shaped clamping block of the clamping mechanism achieves automatic centering and stable clamping of the cable, preventing bending and deformation of the cable during cutting, thereby ensuring the accuracy of the cutting position. The insulation layer cutting uses a heating plate to heat the cutting blade, stabilizing the cutting blade temperature near the melting point of the insulation layer material. The thermal cutting method can efficiently cut the insulation layer while preventing the cutting blade from cutting too deeply and damaging the conductor, thus ensuring the integrity of the conductor structure and preventing conductor breakage. Subsequently, the rotating mechanism drives the cutting mechanism to complete the circular cutting, combined with the vertical cutting after the rotating motor drives the cutting blade to turn, forming a combined circular and vertical insulation layer cutting method. This method can quickly peel off the insulation layer, reduce manual operation steps, and at the same time, the heating cutting method reduces the cutting resistance of the insulation layer and improves the cutting efficiency. Then, the conductor of the cable is cut. Attached Figure Description

[0021] The technical solutions of this utility model will be clearly and completely described below with reference to the embodiments of this utility model. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this utility model.

[0022] Examples, such as Figures 1-5 As shown, this embodiment proposes a cable cutting machine, including a base 1, on which a guide rail drive mechanism 2 is provided. For example, the guide rail drive mechanism 2 can be driven by a motor and a lead screw. A rotating support 3 is installed on the guide rail drive mechanism 2, and a cutting mechanism 4 is provided on the rotating support 3 for cutting the insulation layer and conductor of the cable respectively. The cutting machine is also provided with a clamping mechanism 5 to clamp the cable. A rotating mechanism 6 is provided on the rotating support 3 for driving the rotating support 3 to rotate. The cutting mechanism 4 includes a mounting bracket 401, on which a rotating motor 402 is fixedly connected. An electric telescopic rod 403 is fixedly connected to the output end of the rotating motor 402. A cutting blade 406 is fixedly connected to the output end of the electric telescopic rod 403. A heating plate 404 is fixedly connected to the end of the electric telescopic rod 403 near the cutting blade 406. A guide groove 409 is opened in the heating plate 404. The heating plate 404 can be heated by resistance heating, and a temperature sensor is installed inside to assist in precise heating.

[0023] The cable is clamped by the clamping mechanism 5 to prevent bending and deformation during the cutting process, which would affect the cutting. Then, the cable is cut by the cutting mechanism 4. According to the cable cutting steps, the insulation layer of the cable must first be cut. During the cutting process, the cutting blade 406 is heated by the heating plate 404. The temperature of the cutting blade 406 is controlled near the melting point of the insulation material. Then, the electric telescopic rod 403 drives the cutting blade 406 to press down on the insulation layer. The insulation layer of the cable can be easily cut by the hot blade, while avoiding excessive force from the cutting blade penetrating into the conductor surface. At the same time, the rotating mechanism 6 drives the rotating support 3 to rotate, so that the rotating support 3 completes the circular cut of the insulation layer. After the cut is completed, the electric telescopic rod 403 is rotated by the rotating motor 402, and the electric telescopic rod 403 drives the cutting blade 406 to press down again. The guide rail drive mechanism 2 drives the rotating support 3 to move, so that the cutting blade 406 cuts the insulation layer of the cable vertically. Finally, the insulation layer of the cable is separated.

[0024] like Figure 3 As shown, the cutting mechanism 4 also includes hydraulic rods 407. Two hydraulic rods 407 are provided and installed symmetrically. The hydraulic rods 407 are fixedly connected to the mounting bracket 401, and the output end of the hydraulic rods 407 is fixedly connected to a shearing blade 408. By synchronously controlling the hydraulic rods 407, the shearing blade 408 cuts the conductor of the cable.

[0025] like Figure 4 As shown, a scraper 405 is fixedly connected to the end of the heating plate 404 away from the electric telescopic rod 403. Two scrapers 405 are provided and installed symmetrically. By setting the scraper 405, the rubber on the surface of the cutting blade 406 can be scraped off during the retraction of the cutting blade 406, thereby preventing the insulation layer from sticking to the surface of the cutting blade 406 and affecting subsequent processing.

[0026] like Figure 2 As shown, a driven gear 603 is rotatably mounted on the rotating support 3, and a mounting bracket 401 is fixedly connected to the surface of the driven gear 603. A driving gear 602 is rotatably mounted on the rotating support 3, and the driving gear 602 and the driven gear 603 mesh with each other.

[0027] The rotating mechanism 6 includes a servo motor 601, which is fixedly connected to one side of the rotating support 3. The output end of the servo motor 601 is fixedly connected to the drive gear 602. By using the servo motor 601 to drive the drive gear 602 to rotate, the driven gear 603 drives the cutting mechanism 4 to rotate, thereby performing a circular cut on the cable.

[0028] like Figure 2As shown, clamping mechanisms 5 are respectively disposed on the left and right sides of the rotating support 3. One clamping mechanism 5 is fixedly connected to the surface of the base 1, and the other clamping mechanism 5 is fixedly connected to the side of the rotating support 3 near the rotating mechanism 6.

[0029] The clamping mechanism 5 includes a slide rail 501, in which a screw 502 is rotatably mounted. The screw 502 has two threads with opposite directions of rotation. A lifting slide 504 is slidably connected to these two threads. A stepper motor 503 is fixedly connected to the end of the slide rail 501, and the output end of the stepper motor 503 is fixedly connected to the screw 502. A V-shaped clamping block 505 is provided on the lifting slide 504. By using the stepper motor 503 to drive the screw 502 to rotate, the V-shaped clamping block 505 on the lifting slide 504 clamps and fixes the cable, preventing it from bending during the cable cutting process. Simultaneously, the automatic centering feature of the V-shaped clamping block 505 ensures that both sides of the cutting position are on the same horizontal plane.

[0030] The working principle is as follows: The cable is passed through the rotating support 3. The stepper motor 503 drives the screw 502 to rotate, causing the V-shaped clamping block 505 to clamp and fix the cable. Then, the heating plate 404 heats the cutting blade 406. After heating to a certain temperature, the electric telescopic rod 403 drives the cutting blade 406 to press down and cut the cable insulation layer. At the same time, the servo motor 601 drives the drive gear 602 to rotate, which in turn drives the cutting mechanism 4 to rotate through the driven gear 603, making a circular cut on the cable insulation layer. Then, the rotating motor 402 drives the electric telescopic rod 403 to rotate 90°, which drives the rotating support 3 to move a certain distance through the guide rail drive mechanism 2. Then, the heating plate 404 heats the cutting blade 406 again, and the electric telescopic rod 403 drives the cutting blade 406 to press down and cut the insulation layer vertically. Then, the guide rail drive mechanism 2 drives the rotating support 3 to move to a suitable position. Finally, the synchronous control hydraulic rod 407 drives the shearing blade 408 to press down and cut the cable conductor.

[0031] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model shall be included within the protection scope of the present utility model.
