Description

Technical Field

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

[0002] Wires and cables are wire products used to transmit electrical energy, information, and realize the conversion of electromagnetic energy. In a broad sense, wires and cables are also simply referred to as cables. In a narrow sense, cables refer to insulated cables, which consist of one or more insulated conductors and their respective possible covering layers, overall protective layers, and outer sheaths. Cables may also have additional uninsulated conductors. When in use, wires and cables need to be connected and installed with other electrical equipment to ensure the normal operation of the power system.

[0003] During installation, wires and cables need to be cut to the required length. If the cut length is insufficient, the cable will not be able to reach the equipment to be connected. If the cut length is too long, the excess length will be wasted, increasing unnecessary costs. Therefore, this solution provides a wire and cable cutting device to solve the above-mentioned problems. Utility Model Content

[0004] To solve the above-mentioned technical problems, a cutting device for wires and cables is provided. This technical solution addresses the issue raised in the background art where, during installation, wires and cables need to be cut to the required length. If the cut length is insufficient, the cable will not be able to reach the equipment to be connected. If the cut length is too long, the excess length will be wasted, increasing unnecessary costs.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows: a wire and cable cutting device, comprising a base, with support rods fixedly installed at the four corners of the upper end of the base, a top plate fixedly installed at the upper end of the four support rods, a control panel provided at the front end of the right-hand support rod, a displacement sensor provided at the left end of the right-hand support rod at the rear end, a cutting table fixedly installed in the middle of the upper end of the base, a cutting groove provided at the upper end of the cutting table, and two connecting rods fixedly connected to the rear side of the upper end of the base, with a first fixing device fixedly connected to the upper end of the two connecting rods.

[0010] Compared with the prior art, the present invention provides a wire and cable cutting device, which has the following advantages:

[0011] First, the cable is clamped and fixed by two limiting plates. Then, the length to be cut is input on the control panel. The control panel then controls the servo motor to drive the one-way threaded rod to rotate. The rotation of the one-way threaded rod drives the moving block to move to the right, which in turn drives the clamped cable to move to the right. During the movement of the moving block to the right, the positioning block set at the upper end of the moving block moves to the right. When the displacement sensor detects that the set length has been reached, the movement stops. Then, the hydraulic cylinder drives the cutting blade to cut the cable, thereby accurately obtaining the required cable length. Attached Figure Description

[0018] The following description is intended to disclose the present invention so that those skilled in the art can implement it. The preferred embodiments described below are merely examples, and other obvious variations will occur to those skilled in the art.

[0019] Reference Figures 1-4As shown, a wire and cable cutting device includes a base 1. Support rods 2 are fixedly installed at the four corners of the upper end of the base 1. A top plate 4 is fixedly installed at the upper end of the four support rods 2. A control panel 3 is installed at the front end of the right-hand support rod 2. The control panel 3 can be of the Siemens brand. The TP700 control panel 3 can be any existing control panel capable of performing this function, without limitation. The control panel 3 is electrically connected to the displacement sensor 5, servo motor 11, hydraulic cylinder 21, and electric telescopic rod 31. A displacement sensor 5 is installed at the left end of the rear right support rod 2. The displacement sensor 5 can be of model UM30-2030. Any existing displacement sensor capable of performing this function can be used, without limitation. A cutting table 6 is fixedly installed in the middle of the upper end of the base 1. A cutting groove 7 is opened at the upper end of the cutting table 6. The shape of the cutting groove 7 is the same as that of the cutting blade 23. When the cutting blade 23 cuts the cable, the cutting blade 23 inserts into the cutting groove 7. Two connecting rods 8 are fixedly connected to the rear side of the upper end of the base 1. A first fixing frame 9 is fixedly connected to the upper end of the two connecting rods 8. A rectangular opening 13 is opened at the upper end of the first fixing frame 9. A one-way threaded rod 10 is rotatably installed inside the first fixing frame 9. A servo motor 11 is fixedly installed at the right end of the fixed frame 9. The output end of the servo motor 11 extends into the interior of the first fixed frame 9 and is fixedly connected to the right end of the one-way threaded rod 10. A moving block 12 is threadedly connected to the outer surface of the one-way threaded rod 10. A positioning block 14 is fixedly connected to the upper end of the moving block 12. The positioning block 14 is slidably connected to the interior of the rectangular opening 13. A second fixed frame 15 is fixedly connected to the front end of the moving block 12. A bidirectional threaded rod 16 is rotatably installed inside the second fixed frame 15. Limiting blocks 19 are threadedly connected to both the front and rear ends of the outer surface of the bidirectional threaded rod 16. A limiting plate 20 is fixedly connected to the lower end of the limiting block 19. The two limiting plates 20 are arc-shaped and have rubber pads on their inner sides. The rubber pads can increase the friction between the limiting plate 20 and the cable, making the clamping more secure. A rotating rod 17 is fixedly connected to the front end of the bidirectional threaded rod 16. The front end of the rotating rod 17 extends to the outside of the second fixed frame 15 and is fixedly connected to a rotating disk 18.

[0020] Reference Figures 1-3As shown, a hydraulic cylinder 21 is fixedly installed on the upper end of the top plate 4. The output end of the hydraulic cylinder 21 passes through the top plate 4 and is fixedly connected to a mounting plate 22. A cutting blade 23 is provided at the lower end of the mounting plate 22. The blade edge of the cutting blade 23, the right ends of the two limiting plates 20, and the right end of the positioning block 14 are all located on the same vertical plane. Extension blocks 24 are fixedly connected to both the front and rear ends of the mounting plate 22. The lower part of the extension blocks 24 is aligned with the buffer plate 28. Fixing blocks 25 are fixedly connected to both the front and rear ends of the cutting table 6. A telescopic cylinder 27 is fixedly connected to the upper end of the fixing block 25. A buffer plate 28 is fixedly connected to the upper end of the telescopic cylinder 27. A buffer spring 26 is sleeved on the outer surface of the telescopic cylinder 27. The upper and lower ends of the buffer spring 26 are fixedly connected to the lower end of the buffer plate 28 and the upper end of the fixing block 25, respectively. When the cutting blade 23 moves downward to cut the cable, the cutting blade... The extension blocks 24 at both ends of the 23 will contact the buffer plate 28. The buffer plate 28 compresses the buffer spring 26 and the telescopic cylinder 27, thereby buffering the cutting blade 23 and preventing damage to the cutting blade 23 due to downward force during the cutting process. Two upright plates 29 are fixedly connected to the upper left side of the base 1. A first roller 30 is rotatably installed between the two upright plates 29. An electric telescopic rod 31 is fixedly connected to the lower end of the top plate 4. A limit frame 32 is fixedly connected to the output end of the electric telescopic rod 31. A second roller 33 is rotatably installed inside the limit frame 32. The electric telescopic rod 31 drives the second roller 33 to move downward, so that the lower end of the second roller 33 abuts against the cable. In conjunction with the first roller 30, the outer surface of the cable can be limited, thereby limiting both ends of the cutting part, which facilitates the cutting blade 23 to cut.

[0021] The working principle and usage process of this utility model are as follows: First, the cable is passed between the first roller 30 and the second roller 33. Then, the cable is placed between the two limiting plates 20, with its end aligned with the right end of the two limiting plates 20. Next, the rotating disk 18 is rotated, causing the bidirectional threaded rod 16 to rotate. The rotation of the bidirectional threaded rod 16 causes the limiting blocks 19 to move towards each other. The movement of the limiting blocks 19 towards each other causes the two limiting plates 20 to move towards each other, thus clamping and fixing the cable through the two limiting plates 20. Then, the control panel 3 controls the electric telescopic rod 31 to move the limiting frame 32 downwards, causing the second roller 33 inside the limiting frame 32 to cooperate with the first roller 30 to limit the outer surface of the cable. Then, the cable length to be cut is input on the control panel 3. Next, the control panel 3 controls the servo motor 11 to drive the unidirectional threaded rod... When rod 10 rotates, the one-way threaded rod 10 rotates, causing the moving block 12 to move to the right. The moving block 12 moves to the right, causing the second fixed frame 15 to move to the right. The second fixed frame 15 moves to the right, causing the two limiting plates 20 at the lower end of the moving block 12 to move to the right, which in turn causes the cable to move to the right. Since the right end of the positioning block 14, the right end of the two limiting plates 20, and the blade of the cutting blade 23 are all located on the same vertical plane, the distance that the positioning block 14 moves is the distance that the cable moves. When the displacement sensor 5 detects that the distance moved is the same as the distance input on the display screen, the moving block 12 stops moving. Then, the control panel 3 controls the hydraulic cylinder 21 to drive the cutting blade 23 to move downward, which can precisely cut the cable and avoid wasting material due to excessive cutting or making it unusable due to insufficient cutting.
