Description

Technical Field

[0001] This utility model relates to the field of cable production technology, specifically to a cable forming and stabilizing device for a cable forming machine. Background Technology

[0002] In the cable production process, the cable forming machine is a key piece of equipment that enables multiple insulated cores or cables to be stranded according to the designed stranding method. The stranding quality is directly related to the core indicators of the cable, such as conductivity, tensile strength, and weather resistance. After the cable completes the initial stranding through the winch mechanism, it needs to be stably transported along the preset routing path to subsequent processes such as armoring and sheathing. Therefore, the stabilizing device downstream of the winch mechanism becomes a key link to ensure the consistency of the cable formation and avoid cable deformation or positional deviation. Referencing patent publication number CN212750495U - Chinese Utility Model Cable Forming and Stabilizing Device, existing cable forming and stabilizing devices use a stabilizing shaft assembly, which has the following drawbacks: First, the stabilizing shaft assembly is passively rotated, which is prone to speed mismatch due to changes in cable tension, causing wear on the cable surface or torsional stress concentration. Second, when multiple cables are simultaneously stabilized, it is difficult to ensure that their relative positions are consistent, which can easily lead to problems such as loose strands and uneven pitch. Utility Model Content

[0003] The main purpose of this utility model is to provide a cable forming and stabilizing device for a cable forming machine, in order to solve the problems of the existing technology where the stabilizing shaft group is passively rotated, which is prone to speed mismatch due to changes in cable tension, resulting in wear or torsional stress concentration on the cable surface; and when multiple cables are stabilized synchronously, it is difficult to ensure that their relative positions are consistent, which can easily cause problems such as loose strands and uneven pitch.

[0004] To achieve the above objectives, this utility model provides a cable forming and stabilizing device for a cable forming machine, which is located downstream of the winch mechanism and includes a frame, a stabilizing mechanism, and a driving mechanism.

[0005] An extension plate is fixed on one side of the frame. The extension plate is arranged horizontally along the direction of the cable routing, and multiple sets of cable stabilizing mechanisms are arranged at intervals along its length.

[0006] Each stabilizing mechanism includes a mounting plate, an upper bearing, and a straight tube;

[0007] The bottom end of the vertically mounted plate is fixedly connected to the extension plate, and a bearing hole extends through the extension plate along its length.

[0008] The outer ring of the upper bearing is fixedly sleeved in the bearing hole, and the inner ring is fixedly sleeved with a wire stabilizing ring. The wire stabilizing ring has multiple through holes along the axial direction of the bearing hole for the cable to pass through.

[0009] One end of the straight tube is coaxially connected to the stabilizing ring, and the other end is fixedly fitted with a spur gear;

[0010] The drive mechanism drives multiple upper spur gears to rotate synchronously.

[0011] A preferred embodiment is that the drive mechanism includes a rotating shaft and multiple lower spur gears;

[0012] Multiple lower spur gears are fixedly mounted on the rotating shaft, and the number of them is the same as that of multiple upper spur gears. The multiple upper spur gears correspond one-to-one with the multiple lower spur gears, and the two mesh with each other. The rotating shaft is rotatably mounted on multiple mounting plates through multiple lower bearings.

[0013] A shaft is a drive component used to rotate it.

[0014] A preferred embodiment is that the drive unit includes an upper pulley, a lower pulley, and a first motor;

[0015] The extension plate has a through slot, the upper pulley is fixedly sleeved on the rotating shaft, the base of the first motor is fixedly mounted on the bottom wall of the extension plate, and the output shaft is fixedly sleeved on the lower pulley. The lower pulley and the upper pulley are fitted with belts, and the belts pass through the through slot.

[0016] A preferred solution is to have two guide tubes coaxially connected on both sides of the through hole.

[0017] A preferred embodiment is that the winch mechanism includes a main shaft, a rear ring, and a central ring;

[0018] The main spindle is horizontally mounted on the frame. One end of the main spindle is coaxially fixed with a front ring, and the other end is connected to a drive mechanism for rotating it.

[0019] The rear ring is fixedly sleeved in the middle of the main shaft, and multiple sets of wire reel seats are installed on one side of the circumference;

[0020] The central ring is fixedly mounted on the main shaft and located between the rear ring and the front ring. Each central ring is equipped with multiple guide wheels that rotate circumferentially.

[0021] The front ring body has multiple through holes for cable routing, located between the middle ring body and the cable stabilizing mechanism.

[0022] A preferred embodiment is that the driving mechanism includes a driven sprocket and a second motor;

[0023] The base of the second motor is fixedly connected to the frame, and the output shaft is fixedly fitted with a drive sprocket. The driven sprocket and the drive sprocket are fitted with a chain.

[0024] A preferred embodiment is that the wire reel seat includes a flange, a shaft, and a limiting post for limiting the wire reel;

[0025] The flange is fixed on one side of the rear ring body. One end of the shaft is fixedly connected to the flange, and the other end is threaded with an external thread along the axial circumference of the main shaft. One end of the limiting post is threaded with an internal thread hole on the same axis. The external thread is screwed into the internal thread hole. The wire reel is sleeved on the shaft.

[0026] A preferred arrangement is that the main shaft is coaxially arranged with multiple stabilizing rings.

[0027] The beneficial effects of the above scheme are:

[0028] After initial stranding by the upstream winch mechanism, the cable core moves horizontally along the production line, sequentially passing through through holes in the stabilizing rings of multiple stabilizing mechanisms. Each through hole can guide a single core or the entire cable core, ensuring its precise positioning. The drive mechanism activates, generating power and outputting synchronized rotational motion. Since all upper spur gears are driven by the same drive mechanism, they maintain perfectly synchronized rotational speeds and the same direction of rotation. The rotation of the upper spur gears drives the straight tubes fixed to them to rotate synchronously, which in turn drives the stabilizing rings coaxially connected to them to rotate smoothly and at high speed within the inner ring of the upper bearing. The inner wall of the through hole of the rotating stabilizing ring contacts the moving cable surface. At this point, traditional sliding friction is converted into rolling friction. This active rotation matches the forward and stranding rotational motion of the cable, greatly reducing frictional resistance and scratching wear on the cable surface. Simultaneously, the coordinated rotation of multiple stabilizing rings provides a stable and uniform constraint environment for the cable core, effectively preventing positional misalignment of the cores due to tension fluctuations. This ensures the uniformity of the stranding pitch and the tightness of the cable core structure, avoiding defects such as loose strands and deformation. After being actively guided and stabilized by this device, the cable core, in a stable and regular shape, is output from the last stabilizing mechanism and smoothly enters downstream processes such as sheathing and armoring.

[0037] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Many specific details are set forth in the following description 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.

[0038] Example:

[0039] like Figures 1-5 As shown, this embodiment provides a cable forming and stabilizing device for a cable forming machine, located downstream of the winch mechanism 5. The cable forming and stabilizing device includes a frame 10, a stabilizing mechanism 30, and a driving mechanism 40. An extension plate 20 is fixed to one side of the frame 10, and the extension plate 20 is horizontally arranged along the direction of the cable routing, as shown... Figure 1 As shown, multiple sets of stabilizing mechanisms 30 are arranged at intervals along the length of the extension plate 20. Each stabilizing mechanism 30 includes a mounting plate 31, an upper bearing 32, and a straight tube 33. The bottom end of the vertically arranged mounting plate 31 is fixedly connected to the extension plate 20, and the vertically arranged mounting plate 31 passes through the bearing hole 310 along the length of the extension plate 20. Figure 5 As shown, the outer ring of the upper bearing 32 is fixedly sleeved within the bearing hole 310, and the inner ring of the upper bearing 32 is fixedly sleeved with a cable stabilizing ring 34. The cable stabilizing ring 34 has multiple through holes 35 along the axial direction of the bearing hole 310 for cable passage. Two guide tubes 37 are coaxially connected to both sides of the through holes 35. One end of a straight tube 33 is coaxially connected to the cable stabilizing ring 34, and the other end of the straight tube 33 is fixedly sleeved with a spur gear 36. Figure 3 As shown, the drive mechanism 40 drives multiple upper spur gears 36 to rotate synchronously. The drive mechanism 40 includes a rotating shaft 41 and multiple lower spur gears 42. Figure 5As shown, multiple lower spur gears 42 are fixedly mounted on a rotating shaft 41, and the number of lower spur gears 42 is the same as the number of upper spur gears 36. Each upper spur gear 36 corresponds one-to-one with a lower spur gear 42, and they mesh with each other. The rotating shaft 41 is rotatably mounted on multiple mounting plates 31 via multiple lower bearings (not shown). The rotating shaft 41 is connected to a drive component 43 for rotating it. Figure 3 As shown, the driving component 43 includes an upper pulley 431, a lower pulley 432, and a first motor 433. The extension plate 20 has a through slot 21. The upper pulley 431 is fixedly mounted on the rotating shaft 41. The base of the first motor 433 is fixedly mounted on the bottom wall of the extension plate 20, and the output shaft of the first motor 433 is fixedly mounted on the lower pulley 432. A belt 435 is fitted onto the lower pulley 432 and the upper pulley 431, passing through the through slot 21. The first motor 433 drives the lower pulley 432 to rotate. The lower pulley 432 drives the upper pulley 431 to rotate via the belt 435. The upper pulley 431 drives the rotating shaft 41 to rotate, which in turn drives multiple lower spur gears to rotate synchronously, further driving multiple upper spur gears to rotate synchronously.

[0040] After initial stranding by the upstream winch mechanism 5, the cable core moves horizontally along the production line, sequentially passing through through holes 35 on the stabilizing rings 34 of multiple stabilizing mechanisms 30. Each through hole 35 can guide a single core or the entire cable core, ensuring its position is precisely defined. The drive mechanism 40 is activated, generating power and outputting synchronized rotational motion. Since all upper spur gears 36 are driven by the same drive mechanism 40, they always maintain perfectly synchronized rotational speeds and the same rotational direction. The rotation of the upper spur gears 36 drives the straight tube 33 fixed to them to rotate synchronously, and the straight tube 33 in turn drives the stabilizing ring 34, which is coaxially connected to it, to rotate smoothly and at high speed in the inner ring of the upper bearing 32. The inner wall of the through hole of the rotating stabilizing ring 34 contacts the moving cable surface. At this time, traditional sliding friction is converted into rolling friction. This active rotation matches the forward movement and stranding rotation of the cable, greatly reducing frictional resistance and scratching wear on the cable surface. Simultaneously, the multiple synchronously rotating stabilizing rings 34 work together to provide a stable and uniform constraint environment for the cable core, effectively preventing positional misalignment of each core due to tension fluctuations. This ensures the uniformity of the stranding pitch and the tightness of the cable core structure, avoiding defects such as loose strands and deformation. After being actively guided and stabilized by this device, the cable core is output from the last stabilizing mechanism 30 in a stable and regular shape, and smoothly enters the downstream processes such as sheathing and armoring.

[0041] like Figure 3As shown, the winch mechanism 5 includes a main shaft 51, a rear ring body 52, and a central ring body 53. The main shaft 51 is coaxially arranged with multiple stabilizing ring bodies 34. The main shaft 51 is horizontally mounted on the frame 10. One end of the main shaft 51 is coaxially fixed to the front ring body 54, and the other end of the main shaft 51 is connected to a drive mechanism 55 for rotating it. The drive mechanism 55 includes a driven sprocket 551 and a second motor 552. The base of the second motor 552 is fixedly connected to the frame 10, and its output shaft is fixedly fitted with a drive sprocket 553. The driven sprocket 551 and the drive sprocket 553 are fitted with a chain 554. The rear ring body 52 is fixedly fitted in the middle of the main shaft 51, and multiple sets of wire reel seats 56 are installed on one side of the circumference of the rear ring body 52. The central ring 53 is fixedly mounted on the main shaft 51 and is located between the rear ring 52 and the front ring 54. Each central ring 53 has multiple guide wheels 57 circumferentially mounted on it. The front ring 54 has multiple through holes 540 for cable passing through and is located between the central ring 53 and the cable stabilizing mechanism 30.

[0042] The specific workflow of the above scheme is as follows: Multiple sets of wire reels are respectively installed on the wire reel seat 56 of the rear ring body 52, and the cable is pulled out from the wire reel. The second motor 552 starts, and the drive sprocket 553 on its output shaft transmits power to the driven sprocket 551 fixed on the main shaft 51 through the chain 554, thereby driving the entire main shaft 51 to rotate on the frame 10. When the main shaft 51 rotates, the rear ring body 52, the middle ring body 53 and the front ring body 54 fixed on it rotate synchronously. The multiple cables led out from the rear ring body 52 first pass around the guide wheel 57 on the middle ring body 53. The function of the guide wheel 57 is to change the direction of the cable, and orderly gather it from the unwinding radius to the stranding radius, preparing for the next step of concentrated stranding. The gathered cable continues to move forward and passes through the through hole 540 opened on the circumference of the front ring body 54. The pre-tensioning ring 54 is the final checkpoint in the stranding process, ensuring that all cables are initially stranded in the designated geometric position, forming the cable core and exiting from the winch mechanism 5. The initially stranded cable core exiting the pre-tensioning ring 54 of the winch mechanism 5 immediately enters the downstream stabilizing mechanism 30. The cable core (or its components) sequentially passes through the through holes on multiple stabilizing rings 34. The drive mechanism 40 is activated, causing the upper spur gear 36 of all stabilizing mechanisms 30 and its connected straight tube 33 and stabilizing rings 34 to rotate synchronously. The rotation direction of the stabilizing rings 34 is opposite to the rotation direction of the main shaft 51. This synchronous rotation in opposite directions can effectively counteract the residual torsional stress generated by the stranding of the cable core, achieving a "torsion relief" effect and making it more stable. The inner wall of the through hole of the rotating stabilizing ring 34 forms rolling friction with the moving cable core surface, greatly reducing the frictional resistance and surface scratches caused by traditional sliding guides. Under the combined action of multiple stabilizing rings 34, the cable core is further straightened and shaped, the stranding pitch becomes uniform and the structure is compact, and finally it is output from the device in a stable and regular form, smoothly entering the subsequent processes such as wrapping and armoring.

[0043] like Figure 3 As shown, the wire reel holder 56 includes a flange 561, a shaft 562, and a limiting post 563 for limiting the wire reel. The flange 561 is fixed to one side of the rear ring body 52. ​​One end of the shaft 562 is fixedly connected to the flange 561, and the other end has an external thread (not shown) along the axial circumference of the main shaft 51. One end of the limiting post 563 has a coaxial internal threaded hole (not shown), and the external thread is screwed into the internal threaded hole. The wire reel is sleeved on the shaft 562. In the prior art, the wire reel is sleeved on the shaft 562 and rotatably sleeved on it through the external thread and the internal threaded hole.
