Technical Field

[0001] This utility model relates to the field of conductor manufacturing technology. More specifically, this utility model relates to a conductor strand tightening correction device. Background Technology

[0002] During the conductor stranding process, defects such as loose strands and skipped wires can easily occur in the outer layer of the conductor due to factors such as equipment vibration, tension fluctuations, or deviations in process parameters. These defects not only affect the appearance quality of the conductor but may also reduce its mechanical strength and electrical performance, leading to product defects. Therefore, conductor straightening is required after stranding. Existing straightening methods mostly rely on manual adjustment or tightening, which suffers from low efficiency, poor consistency, and high labor costs.

[0003] Therefore, there is an urgent need for a wire strand tightening correction device that is simple in structure, easy to operate, and has reliable correction effect. Summary of the Invention

[0015] The present invention will now be described in further detail with reference to the accompanying drawings, so that those skilled in the art can implement it based on the description.

[0016] It should be noted that in the description of this utility model, the terms "horizontal", "longitudinal", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", and "outer" indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings.

Therefore, they should not be construed as limitations on this utility model.

[0017] like Figure 1-3 As shown, this utility model provides a wire strand tightening and correction device, including a workbench with a slide rail 2 mounted on its top surface along its length. Multiple sets of clamps 3 are slidably arranged on the slide rail 2. Wires 7 are sequentially passed through the multiple sets of clamps 3 and pressed by them. The pressing force of the multiple sets of clamps 3 increases sequentially along the forward direction of the wire 7. The lead-in end of the wire 7 is connected to one end of a traction rope, and the other end of the traction rope is wound around an external take-up frame. Each set of clamps 3 includes: The clamp base 304 has a slider 305 at its bottom, and the clamp base 304 is slidably connected to the slide rail 2 through the slider 305; A C-type clamp body 302 is mounted on the clamp base 304. A clamping bolt 301 is installed at the open end of the C-type clamp body 302. The clamping bolt 301 is used to adjust the size of the opening of the C-type clamp body 302. Bolt holes are provided on both sides of the clamp base 304, and a locking bolt is installed in any bolt hole to fasten the base to the slide rail 2.

[0018] In the above technical solution, the workbench serves as the supporting structure for the correction device, providing installation positions for other components. To ensure the overall stability of the correction device, the workbench is made of metal. Three sets of clamps 3 are arranged sequentially on the workbench along the travel direction of the conductor 7. These three sets of clamps 3 are named the first set of clamps, the second set of clamps, and the third set of clamps along the travel direction of the conductor 7. The conductor 7 passes through the three sets of clamps 3. The clamping force of the clamps 3 is adjusted by the clamping bolts 301 at the open end of the C-type clamp body 302. The C-type clamp body 302 is made of hard aluminum alloy. The clamping force of the three sets of clamps 3 increases sequentially along the travel direction of the conductor 7, so as to achieve the correction of loose strands and skipped wires of the conductor 7 using a three-level correction method of "pre-tightening-fine adjustment-shaping", ensuring the correction quality. The conductor 7 is connected to an external take-up frame via a traction rope. The take-up mechanism on the take-up frame rotates, causing the conductor 7 to move forward. During this forward movement, tension fluctuations and issues with the accuracy of the take-up mechanism's drive may cause misalignment between the position to be corrected and the clamp 3, resulting in poor correction quality. Therefore, a slide rail 2 is installed on the worktable, and the clamp 3 is slidably mounted on the slide rail 2 via a slider 305. The position of the clamp 3 can be flexibly adjusted according to the movement of the conductor 7 and the position to be corrected, ensuring precise alignment between the clamp 3 and the position to be corrected and guaranteeing correction quality. This invention corrects the conductor 7 using a jogging method. The process of correcting the conductor 7 using the conductor strand tightening correction device is as follows: First, the wire 7 is placed on the wire release frame. The lead end of the wire 7 is connected to one end of the traction rope, and the other end of the traction rope is connected to the take-up frame. The traction rope is made of aluminum. The height of the wire release frame and the take-up frame is set so that the wire 7 can be driven to move horizontally forward by the traction rope. The inner diameter of the three sets of C-type clamp bodies 302 is adjusted to be larger than the diameter of the wire 7 so that the wire 7 can be passed through the clamp 3. The second step is to drive the take-up frame to move the wire 7 forward through the traction rope to the point a to be corrected, which is located in the first set of clamps 3. The take-up component is then driven to stop rotating. Based on their work experience, the operator adjusts the opening of the C-type clamp body 302 by tightening the clamping bolt 301 to adjust the clamping force and pre-tighten the wire 7 at the point a to be corrected. Then, the opening of the C-type clamp body 302 is adjusted to the initial state by tightening the clamping bolt 301. The third step involves driving the take-up mechanism to pull the wire 7 back to the point a to be corrected, which is located within the second set of clamps 3. The take-up mechanism then stops rotating. The operator moves the first set of clamps 3 until the second point b to be corrected on the wire 7 is located within the first set of clamps 3. The clamping forces of the first set of clamps 3 and the second set of clamps 3 are adjusted respectively. The wire 7 at the point a to be corrected is pre-tightened and then fine-tuned. The wire 7 at the point b to be corrected is initially pre-tightened. The opening of the first set of clamps 3 and the second set of clamps 3 is adjusted to the initial state. Fourth step: The drive take-up component pulls the wire 7 to the point to be corrected (a) within the third set of clamps 3. The drive take-up component stops rotating. The operator moves the second set of clamps 3 to the point to be corrected (b) within the second set of clamps 3, and moves the first set of clamps 3 to the third point to be corrected (c) on the wire 7 within the first set of clamps 3. The clamping force of the first, second, and third sets of clamps 3 is adjusted respectively. The wire 7 at the point to be corrected (a) is fine-tuned and shaped. The wire 7 at the point to be corrected (b) is fine-tuned after initial pre-tightening. The wire 7 at the point to be corrected (c) is initially pre-tightened. The opening of the first, second, and third sets of clamps 3 is adjusted to the initial state. Thus, the correction operation of the wire 7 at the point to be corrected (a) is completed. Fifth, repeat the above steps until all points on traverse 7 that need correction are corrected.

[0019] During the movement of the conductor 7, the position of the clamp 3 can be initially fixed by adjusting the end of the locking bolt to abut against the worktable. This prevents the clamp 3 from moving with the conductor 7, avoiding friction between the clamp 3 and the conductor 7, which could damage the outer surface of the conductor 7 or cause the conductor 7 to get stuck in the clamp 3 due to its movement. When clamping the conductor 7 at the correction point with the clamp 3, the clamp 3 is also fixed with the locking bolt to prevent the clamp 3 from shifting due to the shaking of the conductor 7, which would affect the correction quality.

[0020] This utility model achieves efficient correction of loose strands and skipped wires in the conductor 7 through multi-stage clamps 3, thereby improving the stranding quality. The clamps 3 are designed with adjustable clamping force, which can adapt to the correction and clamping force requirements of conductors 7 of different specifications, reduce manual intervention, reduce labor intensity, and adapt to automated production.

[0021] In another technical solution, two sets of guide support components 4 are symmetrically arranged at both ends of the workbench, which are used to guide the wire 7 into and out of multiple sets of clamps 3. Each guide support component 4 includes a height-adjustable support rod 401 and a support 402 fixedly arranged on the top of the support rod 401. Conical rollers 403 are symmetrically rotatably arranged on both sides of the support 402, and the wire 7 is placed on the conical rollers 403. The workbench includes a horizontal support platform 1 and a lifting support frame 6 arranged at the bottom of the horizontal support platform 1.

[0022] In this technical solution, a set of guide support components 4 is provided at each end of the workbench. The wire 7 is placed between two conical rollers 403 of the guide support components 4. When the lead end of the wire 7 is pulled from the pay-off frame to the first set of clamps 3 by the take-up frame, and when the corrected part of the wire 7 needs to be wound onto the take-up frame, the lead end of the wire 7 must first pass through the corresponding end of the guide support component 4 before advancing to the first set of clamps 3 or being wound onto the take-up frame. The guiding and supporting action of the guide support group allows the wire 7 to smoothly enter or leave the correction device, reducing friction and deviation during the movement of the wire 7. The adjustable height of the guide support components 4 and the workbench allows the height of the correction device to be adaptively adjusted according to the height of the pay-off frame and the take-up frame to meet the height requirements of the production line. The support rod 401 of the guide support assembly 4 can be composed of a rod body and a sleeve. The rod body has multiple first bolt holes along its height direction, and the sleeve has a second bolt hole. The rod body is fitted inside the sleeve. The height of the support rod 401 can be adjusted by passing bolts through the second bolt hole and the first bolt holes at different height positions. The height adjustment method of the lifting support frame 6 of the work platform is the same as the adjustment method of the support rod 401. Pins can be symmetrically installed on both sides of the support 402, and two conical rollers 403 are rotatably connected to the two pins respectively.

[0023] In another technical solution, multiple guide rollers are also slidably arranged on the slide rail 2, which are distributed between multiple sets of clamps 3 and between the clamps 3 and the guide support assembly 4. The top surface of the guide rollers and the inner bottom surface of the C-shaped clamp body 302 are at the same horizontal height.

[0024] In this technical solution, there is a certain distance between the clamp 3 and the guide support assembly 4, as well as between adjacent clamps 3. The wire 7 has a certain weight. During the movement of the wire 7, the wire 7 located between the distances will be in a suspended state. When the wire 7 moves from one clamp 3 to another in a suspended state, a bending point will appear. This bending point will generate concentrated stress, thereby damaging the wire 7. When the suspended wire 7 enters the next clamp 3, it will also rub against the inner edge of the clamp 3, thereby wearing down the wire 7. Therefore, guide rollers are set between the clamp 3 and the guide support assembly 3, as well as between two adjacent clamps 3, so that the suspended wire 7 is supported by the guide rollers. This reduces the bending stress on the wire 7 and helps the wire 7 smoothly enter the clamp 3, ensuring the integrity of the clamp 3 surface. The guide roller also serves as a guide, allowing the wire 7 to move along the preset path and preventing the wire 7 from deviating. The bracket can be slidably installed on the slide rail via a slider. Bearing seats are symmetrically installed on both sides of the bracket. The two ends of the guide roller are connected to the bearing seats on the two brackets respectively. The surface of the guide roller body has a U-shaped groove. The wire 7 is located in the U-shaped groove. The bottom of the U-shaped groove is at the same horizontal height as the inner bottom surface of the C-shaped clamp body 302. The guide roller is slidably set to avoid the guide roller obstructing the movement of the clamp. The number and placement of the guide rollers are determined according to the actual working conditions on site.

[0025] In another technical solution, the clamp base 304 is detachably connected to the C-type clamp body 302 via a rotating shaft 306.

[0026] In this technical solution, the clamp base 304 is detachably connected to the C-type clamp body 302 via the rotating shaft 306. On the one hand, the angle of the clamp 3 can be finely adjusted via the rotating shaft 306 so that the clamping surface of the clamp 3 forms a surface contact with the wire 7, ensuring clamping stability. On the other hand, the C-type clamp body 302 of the appropriate size can be easily replaced according to the diameter of the wire 7 to be corrected, so as to adapt to the correction of wires 7 of different specifications.

[0027] In another technical solution, a flexible pad 303 is embedded on the inner surface of the C-type clamp body 302.

[0028] In this technical solution, the flexible pad 303 is used to prevent damage to the wire 7 when the C-type clamp body 302 clamps. The flexible pad 303 is made of a composite material of rubber and polyurethane.

[0029] In another technical solution, the top surface of the workbench is engraved with scale lines 5 along its length.

[0030] In this technical solution, during the correction process, if the position of the clamp 3 is adjusted in real time according to the location of the point to be corrected each time, the operation is cumbersome and the work efficiency is low. Moreover, if the point to be corrected happens to be at the twisted position of the wire 7, clamping the point with the clamp 3 may damage the wire 7. Therefore, a scale line 5 is engraved on the top surface of the workbench along its length. According to the pitch of the wire 7 to be corrected, the distance between two adjacent clamps 3 is adjusted to be exactly one pitch. The wire 7 within the pitch range is clamped by two adjacent clamps 3 to form a constraint. The clamping force of the clamp 3 can be transmitted to the part of the wire 7 to be corrected within the pitch range, pressing the loose or protruding jumper wires back to their original position. At the same time, it prevents the wire 7 from shifting backward or becoming coiled, ensuring the tightness of the original twisted result of the wire 7 and preventing the wire 7 from being damaged due to improper force.

[0031] Although the embodiments of this utility model have been disclosed above, they are not limited to the applications listed in the specification and embodiments. They can be applied to various fields suitable for this utility model. For those skilled in the art, other modifications can be easily made. Therefore, without departing from the general concept defined by the claims and their equivalents, this utility model is not limited to the specific details and the illustrations shown and described herein.
