Description

Technical Field

[0001] This utility model relates to the field of bending and cutting devices, specifically an automatic bending and cutting device for network cables. Background Technology

[0002] With the rapid development of information technology, network cables are increasingly used in data centers, smart buildings, industrial automation, and other fields, placing higher demands on the precision, efficiency, and consistency of cable processing. Network cables are typically stored in a coiled state before leaving the factory, and the cable body has a certain degree of bending stress and deformation. Direct use can lead to poor connector crimping, unsightly wiring, and even unstable signal transmission. Therefore, when processing patch cords or custom-length network cables, straightening, bending, and cutting processes are necessary to meet actual installation requirements.

[0003] Currently, most common network cable processing equipment uses fixed or semi-adjustable guide structures. The size of their guide channels is usually fixed or only supports overall adjustment. Shielded network cables, due to their outer layer of metal foil or braided mesh, have a thicker overall diameter and stronger rigidity. Flat network cables have a larger thickness but a narrower width. Ordinary unshielded round cables have a thinner diameter and better flexibility. When using the same equipment to process these different types of cables, for thicker or thicker cables, a guide channel that is too small will cause compression, damage to the insulation layer, or even conductor deformation. For thinner round cables, a channel that is too large cannot effectively restrain them. During high-speed transport, the cables are prone to vertical jumping, horizontal deviation, or rotation, affecting the straightening effect and cutting accuracy. Therefore, we propose an automatic bending and cutting device for network cables. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides an automatic bending and cutting device for network cables, which can effectively solve the problems in the background technology.

[0005] Technical solution

[0006] To achieve the above objectives, the technical solution adopted by this utility model is as follows: an automatic bending and cutting device for network cables, including a bending and cutting mechanism, wherein a straightening mechanism and a guide component are sequentially provided on the top of the bending and cutting mechanism;

[0007] The guide assembly includes two support plates, with a sliding rod and a lead screw disposed between the two support plates. The sliding rod is fixedly connected to the side walls of the two support plates, and the lead screw is rotatably connected to the side walls of the two support plates. One end of the lead screw extends out of the support plate and is fixedly connected to an adjusting handle. Two guide blocks are disposed on the outer surfaces of the sliding rod and the lead screw, and an adjusting assembly is disposed on the upper end of the guide blocks.

[0008] Furthermore, the cross-section of the guide block near the straightening mechanism is tapered, and the guide block is provided with a sliding groove that is slidably connected to the sliding rod and a threaded groove that is threadedly connected to the lead screw.

[0009] Furthermore, a limit block is fixedly connected to the upper end of the guide block, and a limit groove is formed on one side of the guide block.

[0010] Furthermore, the adjusting assembly includes a threaded rod, the bottom of which is rotatably connected to the top of the limiting block, and a sliding element is threaded onto the outer surface of the threaded rod.

[0011] Furthermore, the sliding member includes an outer sliding frame, which is fitted against the outer side wall of the limiting block. A guide plate is fixedly connected to one side of the outer sliding frame, and the guide plate is fitted against the side wall of the limiting groove. A bending frame is fixedly connected to the top of the outer sliding frame, and the bending frame is threadedly connected to the outer surface of the threaded rod.

[0012] Furthermore, the straightening mechanism includes two adjusting frames, with adjusting rollers rotatably connected to the two adjusting frames.

[0013] Beneficial effects

[0014] Compared with the prior art, this utility model provides an automatic bending and cutting device for network cables, which has the following advantages:

[0015] In this automatic bending and cutting device for network cables, the adjustment component at the upper end of the guide block has an independent fine-tuning function for the height of a single guide block. By adjusting this component, the vertical dimension of the opening at the upper end of the guide block can be precisely changed, thereby achieving fine adjustment of the clamping gap of the guide channel on one side. When processing thicker shielded network cables or flat network cables, the guide pressure block can be raised or the clamping space can be released to avoid damage to the cable due to pressure. When processing thinner round network cables, the clamping height can be lowered to reduce the guide gap, effectively suppressing the vertical jump, radial offset or vibration of the cable during high-speed conveying, ensuring that it enters the subsequent straightening and processing station smoothly and centrally, significantly improving the guiding accuracy and processing stability.

[0021] To make the technical means, creative features, and achieved objectives and effects of this utility model readily understandable, the present utility model will be further described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0022] To address the shortcomings of existing technologies, such as Figure 1-4 As shown, this utility model provides an automatic bending and cutting device for network cables, including a bending and cutting mechanism 1, and a straightening mechanism and a guide assembly are sequentially provided on the top of the bending and cutting mechanism 1.

[0023] The guide assembly includes two support plates 2, a sliding rod 3 and a lead screw 4 are arranged between the two support plates 2, the sliding rod 3 is fixedly connected to the side wall of the two support plates 2, the lead screw 4 is rotatably connected to the side wall of the two support plates 2, one end of the lead screw 4 extends out of the support plate 2 and is fixedly connected to an adjustment handle 5, two guide blocks 6 are arranged on the outer surface of the sliding rod 3 and the lead screw 4, and an adjustment assembly is arranged on the upper end of the guide block 6;

[0024] The bending and cutting mechanism 1 is the core processing unit for bending and cutting. This mechanism integrates a servo-driven bending die and a high-precision pneumatic cutting blade assembly, which can perform fixed-length bending and precise cutting of the network line. The straightening mechanism and guide assembly are located at the top of the bending and cutting mechanism 1 in the wire infeed direction, which are used to pre-process and stably transport the network line drawn from the take-up drum, ensuring the processing accuracy of subsequent bending and cutting processes.

[0025] The guide assembly is used to guide the network line smoothly into the straightening mechanism along a predetermined path, preventing the line from deviating or twisting. The guide assembly has two parallel and symmetrically arranged support plates 2, which are fixedly connected by a crossbeam or base to form a stable frame structure. A sliding rod 3 and a lead screw 4 are arranged horizontally between the two support plates 2. The sliding rod 3 is an optical shaft structure, and its two ends are fixed to the side walls of the two support plates 2 by interference fit or screws, which plays a guiding and supporting role. The lead screw 4 is a bidirectional lead screw 4, which is rotatably connected to the side walls of the two support plates 2 through a bearing seat, ensuring that it can rotate freely without axial displacement. The adjustment handle extending outward from one end of the lead screw 4 is an ergonomically designed knob or handwheel with anti-slip texture on the surface, which is convenient for the operator to manually rotate the lead screw 4.

[0026] Guide blocks 6 are fitted on the outer surfaces of the sliding rod 3 and the lead screw 4. Each guide block 6 has a linear bearing hole that matches the sliding rod 3 and a threaded hole that meshes with the lead screw 4. This allows the guide block 6 to move precisely along the axial direction under the guidance of the sliding rod 3 when the lead screw 4 rotates. The relative position of the two guide blocks 6 determines the spacing between them, thereby adapting to network lines of different diameters or flat structures.

[0027] The adjustment component at the upper end of the guide block 6 has the ability to independently fine-tune the height of a single guide block 6. By changing the height of the opening at the upper end of the guide block 6, the vertical clamping distance of the guide channel on one side can be adjusted. When handling thicker shielded network cables or flat network cables, the clamping space can be expanded; while for thinner round cables, the clamping space can be lowered to reduce the gap and prevent the cable from jumping up and down or shifting during the transportation process.

[0028] More importantly, the design supports independent adjustment on one side. In practical applications, if the network cable itself has a slight bend or the cable entry path is not completely symmetrical, the clamping height of the guide block 6 on one side can be adjusted to achieve dynamic balance correction of the cable in the vertical plane, ensuring that it enters the straightening mechanism in a horizontal posture. The independent fine-tuning capability effectively compensates for mechanical assembly errors, cable deformation, or wear and tear after long-term use of the equipment, significantly improving the adaptability and stability of the guiding system.

[0029] The cross-section of the guide block 6 near the straightening mechanism is tapered. The guide block 6 has a sliding groove that is slidably connected to the sliding rod 3 and a threaded groove that is threadedly connected to the lead screw 4. The upper end of the guide block 6 is fixedly connected to the limit block 7, and a limit groove 8 is opened on one side of the guide block 6 to limit the degree of freedom of the guide block 6 in the vertical direction, prevent it from jumping up and down or tilting during the transmission of the lead screw 4, and improve the stability and repeatability of the adjustment process.

[0030] Each guide block 6 has a cross-section designed as a tapered trapezoidal structure near the straightening mechanism. Its outer contour gradually narrows from the inlet end to the outlet end, forming a smooth-transition horn-shaped inlet. This structure not only achieves streamlined optimization in appearance, but more importantly, it significantly improves the smoothness and positioning accuracy of cable guidance.

[0031] The adjusting assembly includes a threaded rod 9, the bottom of which is rotatably connected to the top of the limiting block 7. A sliding element is threadedly connected to the outer surface of the threaded rod 9. The sliding element includes an outer sliding frame 10, which fits against the outer side wall of the limiting block 7. A guide plate 11 is fixedly connected to one side of the outer sliding frame 10, which fits against the side wall of the limiting groove 8. A bending frame 12 is fixedly connected to the top of the outer sliding frame 10, and the bending frame 12 is threadedly connected to the outer surface of the threaded rod 9.

[0032] The outer sliding frame 10 is fitted on the outside of the limiting block 7. A guide plate 11 is fixedly connected to one side of the outer sliding frame 10. The guide plate 11 is inserted into the limiting groove 8 of the guide block 6 and slides against the side wall of the limiting groove 8 to prevent the outer sliding frame 10 from rotating.

[0033] The straightening mechanism includes two adjusting frames 13, with adjusting rollers 14 rotatably connected to the two adjusting frames 13. Gears 15 that mesh with each other are fixedly connected to the outer surfaces of the two adjusting rollers 14 respectively. A drive motor 16 is fixedly connected to one side of the adjusting rollers 14. An electric push rod 17 that is fixedly connected to the adjusting rollers 14 is provided on the top of the adjusting frame 13.

[0034] The straightening mechanism adopts a double-roller linkage adjustable structure, specifically including two parallel adjusting frames 13. These adjusting frames 13 are made of high-strength aluminum alloy or sheet metal welded structure, possessing excellent rigidity and lightweight characteristics. They are mounted on the frame between the guide assembly and the bending and cutting mechanism 1. Adjusting rollers 14 are rotatably connected to the two adjusting frames 13 via bearing seats. The two adjusting rollers 14 are arranged opposite each other in a vertical or inclined direction, forming an upper and lower clamping straightening channel to effectively eliminate bending, twisting, or plastic deformation of the cable caused by winding during the straightening process. Two adjusting rollers 14 are fixedly connected to the shaft heads at the same end with meshing gears 15. The gear pair 15 is a spur gear 15. When the drive motor 16 drives one of the adjusting rollers 14 to rotate, the power is synchronously transmitted to the other adjusting roller 14 through the meshing of the gears 15, causing it to rotate in the opposite direction. This achieves synchronous reverse rotation of the two rollers, ensuring that the network line is subjected to uniform force during clamping and conveying, avoiding damage or deviation of the line caused by dragging on one side. It also has a certain automatic feeding function, improving the automation level of the whole machine.

[0035] The drive motor 16 on one side of the adjusting roller 14 directly drives one of the adjusting rollers 14 through a coupling or gear 15, providing stable power for the straightening and conveying process. The motor speed can be precisely adjusted by the controller to meet the needs of different wire diameters and processing speeds.

[0036] The electric push rod 17 at the top of the adjusting frame 13 has its piston rod end fixedly connected to the bearing seat or roller shaft end of the adjusting roller 14. By controlling the extension and retraction stroke of the cylinder, the center distance or clamping force between the two adjusting rollers 14 can be precisely adjusted.

[0037] The working principle of this application is as follows:

[0038] The operator passes one end of the network wire on the take-up drum through the various functional modules of the device in sequence. It first enters from the guide component, and is guided by the tapered trapezoidal guide block 6 to be smoothly conveyed to the straightening mechanism. Then it enters the downstream bending and cutting mechanism. Before starting, the bending angle, cutting length and other parameters are set by the control system according to the specifications of the network wire being processed.

[0039] By rotating the adjustment handle 5, the lead screw 4 is driven to rotate, which drives the two guide blocks 6 to move synchronously inward or outward along the sliding rod 3, quickly adjusting the lateral distance between the two guide blocks 6 to accommodate network lines of different widths. By rotating the threaded rod 9, the outer sliding frame 10 is driven to rise and fall along the limiting block 7, changing the vertical space of the guide channel, and realizing fine calibration and clamping pressure control of network lines of different diameters or thicknesses in the height direction.

[0040] The network cable first enters the guide assembly and straightening mechanism. After straightening, the network cable is continuously fed into the bending and cutting mechanism. The controller controls the servo motor or encoder to accurately measure the length of the cable according to the preset length signal. When the network cable reaches the designated position, the bending die moves under the drive of the pneumatic or electric actuator to accurately bend the cable to meet the space requirements of RJ45 connector connection or wiring. After bending, the pneumatic shears move quickly to cut the network cable to the set length, with a clean cut without burrs.

[0041] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
