Abstract
Description
Technical Field
[0001] This utility model relates to the field of cable production technology, and in particular to a cable straightening device. Background Technology
[0002] During the production and use of wires and cables, cables often experience varying degrees of bending and deformation due to winding, transportation, or long-term storage, affecting subsequent processing and installation. Traditional manual straightening methods are not only inefficient but also produce unstable straightening results, easily causing surface damage or internal structural destruction of the cable, failing to meet the high demands of modern industry for cable quality and processing efficiency. While some existing mechanical straightening equipment possesses certain automation functions, they generally suffer from complex structures, inconvenient adjustments, and poor adaptability, unable to flexibly address the straightening needs of cables of different specifications. Furthermore, most equipment uses single-point or multi-point linear pressure application, lacking a multi-directional synchronous force application mechanism, resulting in incomplete straightening or significant springback after straightening. Therefore, we propose a cable straightening device. Utility Model Content
[0003] The main objective of this invention is to provide a cable straightening device that can effectively solve the problems in the background art.
[0004] To achieve the above objectives, the technical solution adopted by this utility model is as follows:
[0005] A cable straightening device includes two mounting plates symmetrically arranged front and back. Each mounting plate has mounting holes at its four corners. Slide rails are fixedly connected to opposite ends of the two mounting plates. A straightening mechanism is slidably connected between the two mounting plates via the slide rails. Two uprights are symmetrically fixedly mounted on the upper end of the rear mounting plate. A first-reverse motor is fixedly mounted on one end of one upright. A ball screw is fixedly connected to the output end of the first-reverse motor. The ball screw is movably connected to the two uprights and threadedly connected to the rear of the straightening mechanism.
[0006] The straightening mechanism includes a straightening frame, and both ends of the straightening frame are fixedly connected with sliding sleeves that are slidably connected to the slide rail. The straightening frame is slidably installed between two mounting plates through the two sliding sleeves. A transmission seat is fixedly installed on the upper end of the sliding sleeve located at the rear. The transmission seat is sleeved on the ball screw and threadedly connected to the ball screw.
[0007] A drive assembly is coaxially arranged inside the straightening frame, and three straightening components arranged in a ring array are movably installed inside the drive assembly.
[0008] Preferably, the drive assembly includes an adjustment disc and a second forward and reverse motor. The adjustment disc is movably installed inside the straightening frame and coaxially arranged with the straightening frame. The second forward and reverse motor is fixedly installed on the top of the straightening frame. A drive gear is fixedly connected to the output end of the second forward and reverse motor. The outer surface of the adjustment disc is integrally formed with transmission teeth that mesh with the drive gear.
[0009] By adopting the above technical solution: the drive assembly drives the drive gear to rotate via a second forward and reverse motor, which in turn drives the transmission teeth on the outer surface of the adjustment disc to rotate, thereby realizing the rotational movement of the adjustment disc. The adjustment disc and the straightening frame are coaxially arranged to ensure smooth rotation, providing a basis for the synchronous movement of the subsequent three straightening components. This structure is compact, has high transmission efficiency, and can precisely control the rotation angle of the adjustment disc, thereby achieving precise adjustment of the spacing between the straightening wheels and adapting to the straightening needs of cables of different diameters.
[0010] Preferably, the outer surface of the adjusting disk has three transmission grooves that communicate with the interior of the adjusting disk, and each of the three transmission grooves has a guide component that is movably installed and slidably connected to the straightening component.
[0011] By adopting the above technical solution: the three transmission grooves on the adjustment plate are used to accommodate the guide component and rotate inside it. As the adjustment plate rotates, the guide component rotates along the transmission groove, pushing the straightening rod connected to it to perform extension and retraction actions, thereby adjusting the distance between the straightening wheels. This realizes the mechanical linkage automatic adjustment function, enabling the three straightening wheels to synchronously adapt to cables of different specifications, improving the equipment's versatility and straightening accuracy.
[0012] Preferably, the guide component includes a guide block, and a movable shaft is fixedly connected to the middle of both the front and rear ends of the guide block. The guide block is movably mounted in the transmission groove on the adjusting plate through the movable shaft.
[0013] By adopting the above technical solution: the guide block cooperates with the transmission groove through the movable shaft, and can slide flexibly during the rotation of the adjustment plate and drive the straightening rod to move, forming a stable mechanical linkage mechanism. This structure has good guidance and stability, making the movement of the straightening component smoother, avoiding jamming or deviation, and improving the reliability of equipment operation.
[0014] Preferably, the straightening assembly includes a straightening rod, which is slidably connected within the guide block. One end of the straightening rod is fixedly connected to an installation shaft, and the straightening rod is movably connected to the straightening frame via the installation shaft. A wheel frame is integrally formed at the end of the straightening rod away from the installation shaft, and a straightening wheel is movably connected within the wheel frame.
[0015] By adopting the above technical solution: the straightening rod can slide inside the guide block, one end of which is movably connected to the straightening frame through the mounting shaft, and the other end is connected to the wheel frame and the straightening wheel, forming a complete multi-directional pressure mechanism. When the guide block moves, the straightening rod moves accordingly, driving the straightening wheel to move closer to or away from the center line of the cable, realizing adaptive adjustment. It can automatically adjust according to the change of cable diameter, ensuring uniform force application during the straightening process, preventing cable damage, and improving the straightening effect and applicability.
[0016] Preferably, the middle part of the adjusting plate and the straightening frame are provided with straightening grooves of the same diameter, and the three straightening wheels are arranged in a ring array in the straightening grooves.
[0017] By adopting the above technical solution: the straightening groove is the cable passage, and three straightening wheels are arranged in a ring around the channel to form a multi-directional force structure on the cable, so that it is subjected to pressure from multiple directions during the straightening process, effectively eliminating bending deformation, realizing multi-point synchronous pressurization, improving straightening efficiency and quality, and avoiding the rebound problem caused by traditional single-point pressurization. It is particularly suitable for high-strength and high-precision cable straightening operations.
[0018] Compared with the prior art, the present invention has the following beneficial effects:
[0019] 1. The design, which connects the ball screw to the straightening mechanism, enables precise forward and backward movement control of the straightening mechanism. A primary forward and reverse motor drives the ball screw, causing the transmission seat to slide smoothly along the slide rail, resulting in the entire straightening mechanism reciprocating. This ensures the cable receives continuous and uniform pressure within the straightening groove, improving stability and ease of operation during cable straightening. This design not only enhances the accuracy and response speed of the equipment but also strengthens the controllability of the cable feeding process. It is suitable for straightening cables of various lengths and degrees of curvature, significantly improving work efficiency and straightening consistency.
[0020] 2. Through the coordinated design of the drive and straightening components, especially the combined structure of the adjusting disc and guide, automatic adaptation straightening of cables of different specifications is achieved, significantly improving the equipment's versatility and straightening efficiency. The second forward and reverse motor drives the adjusting disc to rotate, causing the three straightening components to move synchronously. This allows the spacing between the straightening rollers to automatically adjust according to changes in cable diameter, ensuring uniform force application during straightening and preventing damage to the cable surface. Simultaneously, the three straightening rollers arranged in a circular array can apply synchronous pressure to the cable in multiple directions, effectively eliminating residual stress, preventing springback after straightening, and improving straightening quality. This design possesses excellent adaptability and operational flexibility, making it particularly suitable for the application needs of factory cable processing and automated production lines.

The first forward and reverse motor 5 drives the ball screw 6, causing the transmission seat 33 to slide smoothly along the slide rail 2, enabling the entire straightening mechanism 3 to reciprocate. This ensures that the cable receives continuous and uniform pressure within the straightening groove, improving stability and ease of operation during cable straightening. This design not only improves the accuracy and response speed of the equipment but also enhances the controllability of the cable feeding process.
