Description

Technical Field

[0001] This utility model belongs to the field of cable straightening technology, specifically relating to a portable cable bending and straightening device. Background Technology

[0002] In power engineering, communication networks, shipbuilding, and other industrial sectors, cable laying and installation are crucial. However, whether during transportation, storage, or construction, cables are highly susceptible to localized bending due to compression and bending. These bends not only affect aesthetics but can also cause obstacles when cables pass through conduits, cable trays, or equipment interfaces. In severe cases, they can even lead to stress concentration in the cable's internal core wires, affecting its electrical performance and service life.

[0003] For example, Chinese invention patent (CN111992641B) discloses a cable straightening device, including a base, with a rotatable bearing I and a rotatable bearing II fixed on the top of the base. There are multiple bearing I arranged in a row, and multiple bearing II arranged in a row. The outer circumferential surface of bearing I has a circumferential groove I with multiple grooves of different sizes. The outer circumferential surface of bearing II has a circumferential groove II with multiple grooves of different sizes. The row containing bearing I and the row containing bearing II are parallel, and the cable is straightened and transmitted between the two rows. The cable is clamped between the groove I and the opposite groove II. The base is placed on a workbench, and a mounting mechanism for fixing the base to the workbench is fixed on the base. Bearing II is fixed to the base by an adjustment mechanism. The adjustment mechanism realizes the adjustment of the distance between bearing II and bearing I, which can be used to straighten cables of different diameters, improve straightening efficiency, increase the stability of the device, and ensure straightening accuracy.

[0004] In summary, the method of using two rows of bearings to continuously roll and straighten the entire cable is suitable for overall straightening of the cable before it leaves the factory. However, for localized sudden bending of the cable already laid during on-site construction, the device is bulky and cumbersome, requiring a large operating space and a fixed workbench, and cannot be portable.

[0005] The purpose of this invention is to provide a portable cable bending and straightening device, which aims to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: A portable cable bending straightener includes a support frame. A workbench is fixedly installed on the top of the support frame, a second extrusion block is fixedly installed on the front end of the workbench, a drive mechanism is provided at the other end of the workbench, and a cylinder is provided at the end of the workbench away from the second extrusion block. The output end of the cylinder is connected to the drive mechanism. The driving mechanism includes a sliding block, a double-ended screw is rotatably mounted on the top of the sliding block, and first extrusion blocks are symmetrically arranged on both sides of the sliding block. The two first extrusion blocks are respectively arranged on both sides of the worktable. An arc-shaped slider is connected to the top of the first extrusion block, and the other end of the arc-shaped slider is threaded onto the surface of the double-ended screw.

[0007] In a preferred embodiment of this utility model, a rectangular groove is provided at the middle of the top of the sliding block, the middle end of the double-ended screw is disposed inside the rectangular groove, and a rotating handle is fixedly installed at the middle of the double-ended screw.

Detailed Implementation

[0016] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0017] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0018] Secondly, the term "an embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that excludes other embodiments. Example

[0019] Reference Figure 1-4 This is an embodiment of the present invention, which provides a portable cable bending straightener, including a support frame 1; A workbench 2 is fixedly installed on the top of the support frame 1. A second extrusion block 9 is fixedly installed on the front end of the workbench 2. A drive mechanism is provided at the other end of the workbench 2. A cylinder 3 is provided at the end of the workbench 2 away from the second extrusion block 9. The output end of the cylinder 3 is connected to the drive mechanism. The driving mechanism includes a sliding block 4, a double-ended screw 6 is rotatably mounted on the top of the sliding block 4, and first extrusion blocks 8 are symmetrically arranged on both sides of the sliding block 4. The two first extrusion blocks 8 are respectively arranged on both sides of the worktable 2. An arc-shaped slider 7 is connected to the top of the first extrusion block 8, and the other end of the arc-shaped slider 7 is threaded onto the surface of the double-ended screw 6.

[0020] In use, place the bent cable to be straightened horizontally on the workbench 2, with the bent protrusion of the cable facing the second pressing block 9. Activate cylinder 3; the output end of cylinder 3 extends forward, pushing the entire drive mechanism along the workbench 2 towards the second pressing block 9. The movement of sliding block 4 causes the double-headed screw 6 mounted above it and the two symmetrically arranged first pressing blocks 8 to move forward together. When the first pressing block 8 moves to contact the cable, the continued forward force will clamp the cable between the first pressing block 8 and the second pressing block 9. Cylinder 3 continues to apply thrust, at which point the cable... The cable bends in the opposite direction under the action of three points. This reverse bending force overcomes the yield limit of the cable material, causing it to undergo plastic deformation, thereby correcting the original bend. Furthermore, the other end of the arc-shaped slider 7 is threaded onto the double-ended screw 6. When adjusting the clamping angle of the two first pressing blocks 8, the double-ended screw 6 can be manually rotated. Since the threads at both ends of the double-ended screw 6 turn in opposite directions, when it is rotated, the two arc-shaped sliders 7 will move synchronously towards or in the opposite direction, thereby changing the opening angle and position between the two first pressing blocks 8, so that they can better fit the cable surface and achieve uniform force application.

[0021] In summary, the classic straightening principle of three-point bending is scientifically effective. The cylinder 3 provides a continuous and stable straightening force, and a single action can straighten one bending point. Compared with manual tapping, it is more efficient and the effect is more stable. Furthermore, the position of the first pressing block 8 can be adjusted through the arc-shaped slider 7 and the double-headed screw 6, which allows the device to adapt to cables of different diameters or with irregular bends, ensuring that the straightening force is applied evenly to the cable and avoiding cable sheath indentation, deformation or internal damage caused by point contact or uneven force.

[0022] Furthermore, a rectangular groove 5 is provided at the middle of the top of the sliding block 4, the middle end of the double-ended screw 6 is located inside the rectangular groove 5, and a rotating handle 10 is fixedly installed in the middle of the double-ended screw 6.

[0023] When in use, the rectangular groove 5 on the top of the sliding block 4 is used to accommodate and position the middle part of the double-ended screw 6. The shape of the rectangular groove 5 can prevent the double-ended screw 6 from rotating in the groove, so that it can only rotate around its own axis and will not move randomly. When it is necessary to adjust the clamping angle of the two first extrusion blocks 8, the operator can easily drive the double-ended screw 6 to rotate by rotating the rotating handle 10 fixed in the middle of the double-ended screw 6.

[0024] Furthermore, the sliding block 4 is located above the worktable 2, and an extension bar 12 is fixedly installed at the bottom of the sliding block 4. The surface of the extension bar 12 moves through the worktable 2. The output end of the cylinder 3 is fixedly connected to the bottom of the extension bar 12. An inner groove 11 is opened inside the worktable 2. The middle end of the extension bar 12 is located in the inner groove 11. Connecting bars 13 are installed on both sides of the middle part of the extension bar 12. A sliding bar 14 is fixedly installed at the end of the connecting bar 13. The sliding bar 14 is located directly below the first extrusion block 8. A sliding groove 15 is opened on the surface of the sliding bar 14. A slider is provided at the bottom of the first extrusion block 8 and is slidably installed in the sliding groove 15.

[0025] In use, the cylinder 3 drives the entire sliding block 4 to move back and forth by pushing the extension bar 12. The extension bar 12 passes through the worktable 2, and most of its stroke is located in the inner groove 11 of the worktable 2. This provides precise vertical guidance for the movement and prevents the sliding block 4 from tilting up when pressed. It is connected to the sliding bar 14 through the connecting bar 13, and the power is transmitted to both sides of the equipment. The slider at the bottom of the first extrusion block 8 is embedded in the sliding groove 15 of the sliding bar 14. When the sliding bar 14 moves back and forth, the sliding groove 15 will force the first extrusion block 8 to make a strict linear movement together.

[0026] Furthermore, a main handle 16 is fixedly installed at the bottom of the support frame 1, and a pressing block 17 is provided on the surface of the main handle 16. The pressing block 17 is electrically connected to the cylinder 3.

[0027] In use, the operator holds the main handle 16 to move and hold the equipment. By pressing the pressing block 17 provided on the main handle 16 with a finger, an electrical signal is sent to the cylinder 3 to control its extension or retraction.

[0028] Furthermore, the surfaces of both the first extrusion block 8 and the second extrusion block 9 are set to be arc-shaped.

[0029] When in use, the surfaces of the first extrusion block 8 and the second extrusion block 9 that contact the cable are designed to be arc-shaped. The arc-shaped surface can better wrap the outer wall of the cable, changing the straightening force from point contact to surface contact, effectively preventing damage or flattening of the cable insulation layer under huge straightening pressure.

[0030] Furthermore, replaceable flexible pads are provided on the working surfaces of the first extrusion block 8 and the second extrusion block 9.

[0031] During use, a replaceable flexible pad is added to the arc-shaped working surface of the first extrusion block 8 and the second extrusion block 9. This is the most effective protection for the cable. The flexible pad can further buffer the pressure, distribute the load evenly, and increase the friction, completely avoiding the metal extrusion blocks from leaving indentations, scratches or wear on the cable surface. This is especially important for cables with coatings or particularly soft surfaces.
