Description

Technical Field

[0001] This invention relates to the field of cable processing technology, and more specifically to a cable bending device. Background Technology

[0002] Traditional cable bending devices are widely used in power engineering construction, communication line wiring, and industrial equipment assembly. They are mainly used to bend straight sections of cable to specific angles according to installation requirements to adjust the cable routing. They are suitable for basic installation scenarios such as cable trays, distribution boxes, and wall conduits. They can meet the planar bending requirements of cables of different diameters and are a common tool to ensure smooth cable wiring and compliance with equipment installation specifications.

[0003] However, when three-dimensional cabling is required, traditional devices can only complete the bending operation in a single plane. If the cable is to bend simultaneously in both horizontal and vertical planes, the cable must be disassembled and the bending equipment or the device position must be adjusted multiple times. This is not only cumbersome, but also prone to accumulating angle deviations due to multiple positioning, affecting the neatness and installation accuracy of the cable cabling. At the same time, the bending arc cannot be flexibly adjusted, making it difficult to adapt to the cabling needs of complex spaces. Summary of the Invention

Simultaneously, the support component and synchronous clamping component stably fix the cable. In conjunction with the first and second diameter-changing guide wheel assemblies, rotating the second screw drives the first diameter-changing drive block, and rotating the third screw adjusts the position of the mounting block. This allows for the adjustment of the encirclement curvature of the first and second arc-shaped plates as needed, adapting to the diverse bending requirements of cables of different diameters in complex spaces and solving the problems of traditional methods. The device overcomes the limitations of a fixed arc shape. During adjustment, the first arc plate can synchronously move the following plate, thereby adjusting the position of the limiting rod. This ensures that the midpoint of the outer arc surface of the first arc plate and the side of the limiting rod closest to the cable are always on the same vertical plane, preventing the cable from bending during clamping. Simultaneously, the top of the second arc plate is on the same horizontal plane as the surface of the following plate. Furthermore, during the adjustment of the second variable diameter guide wheel assembly, the height of the upper second arc plate remains unchanged, preventing the bending angle deviation caused by the cable end being lifted due to the increase in the diameter of the guide wheel. In addition, when not in use, it can be folded to reduce space occupation and make it more convenient to use. Attached Figure Description

[0033] The present invention will be further described in detail below with reference to embodiments:

[0034] Example 1, as Figures 1-14As shown, the present invention provides a cable bending device, including a horizontal bending mechanism. The horizontal bending mechanism includes a support assembly, a first diameter-changing guide wheel assembly, and a horizontal bending component. The support assembly includes a support leg 11, a support plate 12 fixedly connected to the top of the support leg 11, and a first slide rail 13 fixedly connected to both ends of the top of the support plate 12. A following plate 14 is slidably connected to the surface of the first slide rail 13, and a limit rod 15 is fixedly connected to the surface of the following plate 14. The first diameter-changing guide wheel assembly includes a second slide rail 21, and a first arc-shaped plate 26 is slidably connected to the surface of the second slide rail 21. A follower rod 27 is fixedly connected to the surface of 26, and the end of the follower rod 27 is fixedly connected to the end of the follower plate 14; a vertical bending mechanism is provided, which includes a second variable diameter guide wheel assembly, a synchronous clamping assembly and a vertical bending assembly.

At the same time, the first arc plate 26 drives the following plate 14 to slide synchronously along the first slide rail 13 through the following rod 27, so that the position of the limiting rod 15 on the following plate 14 is adjusted synchronously, always keeping the midpoint of the outer arc surface of the first arc plate 26 and the side of the limiting rod 15 near the cable in the same vertical plane. Then, the second variable diameter guide wheel assembly is adjusted by rotating the third screw 47, driving the middle mounting block. 45 moves on the surface of the third screw 47, thereby driving the mounting blocks 45 on both sides to slide along the sliding frame 44, and then driving the mounting plate 46 to move synchronously. When the mounting plate 46 moves, due to the limitation of the second slider 414, the position of the upper second arc plate 410 remains unchanged. The mounting plate 46 pulls the second support rod 411 to rotate through the guide rod 413, causing the second variable diameter drive block 412 to slide along the guide rod 413. Through multiple second support rods 411, the remaining second arc plate 410 is pushed to move along the fourth slide rail 49, adjusting the encircling arc of the four sets of second arc plates 410. The top of the upper second arc plate 410 is kept at the same level as the surface of the following plate 14 to prevent the cable end from being lifted.

A horizontal bending handle 37 is fixedly connected to the surface of the rotating component 31 near the universal wheels 36. A third groove 38 is provided on one side of the top of the rotating component 31.

[0037] In this embodiment, one end of the cable is passed sequentially through the surface of the first variable diameter guide wheel assembly, between the limiting rod 15 and the first clamping plate 17, until it extends into the surface of the second variable diameter guide wheel assembly, according to the bending requirements. Then, the first screw 18 of the support assembly is rotated to drive the first clamping plate 17 to slide along the first slide groove 16, which, together with the limiting rod 15, clamps the cable horizontally. The rubber pad on the inner side of the first clamping plate 17 prevents the cable from being scratched. Then, the first slider 33 is slid along the second slide groove 32 to determine the position of the bending column 35, and then the first fixing knob 34 is tightened to lock it. The operator holds the horizontal bending handle 37 and pushes the rotating part 31 to rotate around the pivot connected to the support plate 12, with the universal wheel 36 providing auxiliary support. The bending column 35 applies force against the surface of the cable, and with the guidance of the first variable diameter guide wheel assembly, the cable is bent at a preset angle in the horizontal plane.

[0038] Example 3, as Figures 1-14As shown, based on Embodiment 1, the present invention provides a technical solution: Preferably, the second variable diameter guide wheel assembly further includes a third screw 47, a fixing block 48 rotatably connected to the surface of the third screw 47, the surface of the fixing block 48 being fixedly connected to the surface of the sliding sleeve 43, three mounting blocks 45 are provided, the interior of the mounting block 45 located in the middle is threadedly connected to the surface of the third screw 47, a fourth slide rail 49 is fixedly connected to the side of the mounting plate 46 away from the mounting block 45, a second arc-shaped plate 410 is slidably connected to the surface of the fourth slide rail 49, and the inner wall of the second arc-shaped plate 410 rotates. A second support rod 411 is connected, and one end of the second support rod 411 is rotatably connected to a second diameter-changing drive block 412.

The clamping component includes a fourth screw 52, ​​the surface of which is threadedly connected to the inside of the support member 51. A second clamping plate 53 is threadedly connected to the surface of the fourth screw 52. A second guide rod 54 is fixedly connected to the lower end of the second clamping plate 53. Both ends of the second guide rod 54 are fixedly connected to the inner wall of the support member 51. Two sets of clamping components are provided. The vertical bending assembly includes a rotating sleeve 61. A rotating ring 66 is rotatably connected inside the rotating sleeve 61. One side of the rotating ring 66 is fixedly connected to the side of the mounting plate 46 near the mounting block 45. The surface of the rotating sleeve 61... A vertical bending handle 62 is fixedly connected. A fifth slide rail 63 is fixedly connected to the surface of the vertical bending handle 62. A third slider 64 is slidably connected to the surface of the fifth slide rail 63. A vertical bending column 65 is fixedly connected to the surface of the third slider 64. A second fixing knob is threadedly connected to the inside of the third slider 64. The midpoint of the outer arc surface of the first arc plate 26 is on the same vertical plane as the side of the limiting rod 15 near the cable. Four first arc plates 26 are provided. The top of the upper second arc plate 410 is on the same horizontal plane as the surface of the following plate 14. Four second arc plates 410 are provided.

[0039] In this embodiment, after the position of the vertical bending column 65 is determined by moving the third slider 64 along the fifth slide rail 63, the second fixing knob is tightened to lock it. According to the three-dimensional wiring requirements, the sliding sleeve 43 is pushed along the third slide rail 41 to adjust the overall position of the vertical bending mechanism. At the same time, the second slider 414 slides along the third slide groove 38. Then, the fixing knob in the sliding sleeve 43 is tightened to lock it. Subsequently, the fourth screw 52 in the synchronous clamping component support 51 is rotated to drive the second clamping plate 53 to slide along the second guide rod 54, clamping the cable a second time in the vertical direction. After clamping, the operator holds the vertical bending handle 62 and drives the rotating sleeve 61 to rotate around the rotating ring 66. The vertical bending column 65 applies a vertical force to the surface of the cable. With the guidance of the second variable diameter guide wheel assembly, the cable is bent in the vertical plane, and finally the three-dimensional bending of the cable is achieved.

[0040] The working principle of this cable bending device will be explained in detail below.

[0041] like Figures 1-14As shown, during use, first adjust the first variable diameter guide wheel assembly: use a tool to rotate the second screw 23, driving the first variable diameter drive block 24 inside the limiting tube 22 to slide along the tube wall, pushing the first arc plate 26 along the second slide rail 21 through the first support rod 25, changing the encircling arc of the four sets of first arc plates 26. At the same time, the first arc plate 26 drives the following plate 14 to slide synchronously along the first slide rail 13 through the following rod 27, so that the position of the limiting rod 15 on the following plate 14 is adjusted synchronously, always keeping the midpoint of the outer arc surface of the first arc plate 26 and the side of the limiting rod 15 near the cable in the same vertical plane. Then adjust the second variable diameter guide wheel assembly: rotate the third screw 47, driving the middle mounting block 45 to move on the surface of the third screw 47, thereby driving the mounting blocks 45 on both sides to slide along the sliding frame 44, and then driving the mounting plate 46 to move synchronously. When the mounting plate 46 moves, due to the limitation of the second slider 414, the position of the upper second arc plate 410 remains unchanged. The disc 46 pulls the second support rod 411 to rotate via the guide rod 413, causing the second diameter-changing drive block 412 to slide along the guide rod 413. The remaining second arc plate 410 is pushed to move along the fourth slide rail 49 via multiple second support rods 411, adjusting the encircling arc of the four sets of second arc plates 410. The top of the upper second arc plate 410 is kept at the same level as the surface of the following plate 14 to prevent the cable end from being lifted. Then, one end of the cable is passed through the surface of the first diameter-changing guide wheel assembly, the limiting rod 15 and the first clamping plate 17 in sequence according to the bending requirements, until it extends into the surface of the second diameter-changing guide wheel assembly. Then, the first screw 18 of the support assembly is rotated to drive the first clamping plate 17 to slide along the first slide groove 16, and clamp the cable horizontally in conjunction with the limiting rod 15. The rubber pad on the inner side of the first clamping plate 17 prevents the cable from being scratched. Then, the first slider 33 is slid to move along the second slide groove 32. After determining the position of the bending column 35, the first fixing knob 34 is tightened to lock it. The operator grips the horizontal bending handle 37 and pushes the rotating component 31 to rotate around the pivot connected to the support plate 12, with the caster wheel 36 providing auxiliary support. The bending column 35 applies force against the cable surface, and with the guidance of the first variable diameter guide wheel assembly, the cable is bent at a preset angle in the horizontal plane. Then, the third slider 64 is slid along the fifth slide rail 63 to determine the position of the vertical bending column 65. After that, the second fixing knob is tightened to lock it. According to the requirements of three-dimensional cabling, the sliding sleeve 43 is pushed along the third slide rail 41 to adjust the overall position of the vertical bending mechanism. At the same time, the second slider 414... Slide along the third slide groove 38, then tighten the fixing knob inside the sliding sleeve 43 to lock it. Then rotate the fourth screw 52 inside the synchronous clamping component support 51 to drive the second clamping plate 53 to slide along the second guide rod 54, clamping the cable a second time in the vertical direction. After clamping, the operator holds the vertical bending handle 62 and drives the rotating sleeve 61 to rotate around the rotating ring 66. The vertical bending column 65 applies vertical force to the surface of the cable. With the guidance of the second diameter guide wheel assembly, the cable is bent in the vertical plane, and finally the three-dimensional bending of the cable is achieved.

[0042] The present invention has been described in detail above. However, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, any modifications or improvements that do not depart from the spirit of the present invention are within the scope of protection of the present invention.
