Description

Technical Field

[0001] This invention relates to the field of cable-making machine technology, and more specifically to a cable-making machine for cable production and processing. Background Technology

[0002] Cable forming machines are the main production equipment in wire and cable factories. Their core working principle is to use a rotating stranding mechanism (such as a coil stranding, frame stranding, or cage stranding unit) to drive multiple wire cores to spiral strand, so that the wire cores are tightly wound into cable cores according to the specified pitch. At the same time, the take-up device winds the formed cable cores into the finished cable reel, ultimately realizing the continuous and mass production of cables.

[0003] Currently, cable forming machines are generally large due to their large rotary stranding mechanisms. Specifically, the rotary stranding mechanism often adopts a large-diameter turntable structure, with horizontally placed bobbins installed on each turntable. The bobbins are arranged in a circumferential direction, which increases the use of radial space. At the same time, in the axial direction, the turntable also needs to have a large-span cantilever frame. More turntables are equipped on the large-span cantilever frame to accommodate more bobbins, as well as a tensioning mechanism to ensure the tension of the conductors on each bobbin. This results in a large footprint for the entire machine, making it difficult for small and medium-sized cable factories to adapt to multiple machines for parallel production. Summary of the Invention

[0004] To overcome the above-mentioned defects, embodiments of the present invention provide a cable forming machine for cable production and processing, which solves the technical problem in the related art that the cable forming machine occupies too much radial and axial space due to the large-diameter turntable, large-span cantilever frame and multiple sets of cable drums, resulting in redundant space for the whole machine.

[0005] At least one embodiment of the present invention provides a cable-forming machine for cable production and processing, comprising: The frame has a support plate vertically arranged on its upper edge. The support plate has a plurality of cylindrical shafts for supporting the bobbins. The plurality of cylindrical shafts are arranged circumferentially, and each cylindrical shaft is arranged axially along the support plate. A cantilever bracket is provided on the support plate and located between several cylindrical shafts, and the cantilever bracket extends to the outer end of the cylindrical shafts. The cantilever bracket is provided with a tensioning structure and a twisting cylinder. The tensioning structure is located at the end of the cylindrical shafts and is used to tension multiple wires released from several cylindrical shafts respectively. The twisting cylinder is located at the wire outlet end of the tensioning structure and is used to twist multiple wires to the outer periphery of the wire core to form a cable. A take-up structure is provided on the frame and located at the end of the stranding drum away from the support plate. The take-up structure is used to wind up the cable formed by the stranding drum.

[0006] According to one embodiment of this application, the tensioning structure includes: The tensioning disc is fixed vertically on the cantilever bracket. The tensioning disc has a plurality of grooves radially opened on it. Each groove corresponds to a plurality of the cylinder shafts. A slider is slidably arranged in each groove. A tensioning wheel is rotatably arranged on each slider. The wire on the spool can pass around the tensioning wheel. Wherein, after the slider slides toward the center of the tensioning disc, the tensioning wheel can tension the wire.

[0007] According to one embodiment of this application, a guide straightening structure for straightening the conductor is further included. The guide straightening structure is fixedly disposed on the cantilever bracket and located between the tension wheel and the stranding drum. The conductor on the drum can pass through the tension wheel, the guide straightening structure and the stranding drum in sequence.

[0008] According to one embodiment of this application, the guide alignment structure includes: Several guide straightening groups are provided, each of which corresponds to a number of tensioning rollers. Each guide straightening group includes several straightening rollers that are staggered vertically. The wire on the spool can pass through several straightening rollers in the guide straightening group in sequence to straighten the wire. The distance between the guide straightening group and the axis is greater than the distance between the tensioning wheel and the axis, to ensure that the tensioning wheel can tension the conductor.

[0009] According to one embodiment of this application, the support plate, the tensioning plate, and the stranding cylinder are coaxially arranged, and both the support plate and the tensioning plate are provided with through holes for the wire core to pass through.

[0010] According to one embodiment of this application, the spool has a suspended end, and a blocking block is detachably provided on the suspended end. The blocking block is used to limit the spool to prevent it from falling.

[0011] According to one embodiment of this application, a plurality of the cylindrical shafts are arranged axially along the support disk, and the end of each cylindrical shaft is rotatably connected to the support disk, so as to reduce the wire feeding resistance of the spool to the conductor after the cylindrical shaft rotates.

[0012] According to one embodiment of this application, a driving component is further included. The driving component is used to drive the cylinder shaft to rotate. The driving component includes: A central gear, which is rotatably located at the center of the support disk; A plurality of meshing gears are rotatably disposed on the support disk and respectively located around the central gear, and all of the plurality of meshing gears mesh with the central gear; A drive motor is mounted on the support plate and is used to drive the central gear to rotate; Among them, several cylindrical shafts are respectively located at the center of several meshing gears. After the central gear rotates, it can drive several cylindrical shafts to rotate, thereby reducing the friction of the cylindrical shafts on the conductor.

[0013] According to one embodiment of this application, the stranding cylinder has a mold core inside, the mold core has a stranding channel for the wire core to pass through along the central axis, and the mold core also has a plurality of spiral wire channels for the wire channel, and the plurality of spiral wire channels are all connected to the stranding channel so that the wire is gradually twisted and wrapped around the outer periphery of the wire core. The conductors and cores can be formed into a cable after passing through the stranding cylinder.

[0014] According to one embodiment provided in this application, the take-up structure includes: A take-up drum is rotatably mounted on the frame, and the rotation axis of the take-up drum is perpendicular to the axis of the support plate. After the take-up drum rotates, it can wind up the cable. A drive unit is mounted on the frame and is used to drive the take-up drum to rotate.

[0015] This invention provides a cable-making machine for cable production and processing. Compared with the prior art, it replaces the traditional method of horizontally arranged circumferentially arranged spools by assembling several spools for supporting spools along the axial direction on a vertical support plate. Based on reducing the radial dimension of the rotating stranding mechanism on the cable-making machine, it eliminates the connection structure between the large-span cantilever and the multi-layer rotary table. Only one set of cantilever brackets is assembled between several circumferentially arranged spools, which shortens the cantilever span and fixes it to the support plate. On the one hand, it ensures the amount of spools used in the axial direction, and on the other hand, it reduces the overall space occupied by the equipment in the axial direction.

[0016] Furthermore, the tensioning structure and the stranding drum are integrated into the cantilever bracket. The conductor of the spool directly enters the stranding drum through the tensioning structure to complete the forming, eliminating the need for an external independent tensioning and complex support structure.

[0017] In summary, by improving the structure of the rotating winch mechanism of the cable-making machine, the overall structure is made more compact, and the technical problems of excessive radial and axial space occupation and redundant machine footprint caused by the large-diameter turntable, large-span cantilever frame, multiple sets of bobbins and external tensioning mechanism are solved.

[0025] To make the drawings concise and easy to understand, some drawings only show one of the components with the same structure or function, or only one of them is marked. In this article, "one" not only means "only one", but can also mean "more than one", and "several" includes "two" and "more than two".

It is understood that the specific embodiments described herein are merely illustrative of the invention and not intended to limit it. The embodiments of this application are described in detail below with reference to the accompanying drawings.

[0027] like Figure 1 and Figure 2 As shown, a cable-making machine for cable production and processing according to an embodiment of the present invention is illustrated, including a frame 1, a cantilever bracket 4, and a take-up structure 7, etc. Specifically, the bottom frame 1 serves as an integral rigid support frame, which is formed by welding profiles and is used to fix the support plate 2, the cantilever bracket 4, and the take-up structure 7, ensuring the coaxiality and operational stability of each component. The support plate 2 is a vertical polygonal plate structure / circular plate, which is installed through the end of the frame 1 and along the vertical support. The vertical support can be integrally formed with an annular protrusion. The support plate 2 is fitted on the annular protrusion and serves as the core mounting base of the rotating stranding unit. Several cylinder shafts 3 for supporting the cable drum are evenly arranged on it along the circumferential direction. The cylinder shafts 3 are arranged in a horizontal axial direction (consistent with the length direction of the frame 1), and a through hole 12 is opened in the center of the support plate 2 as a through channel for the central main wire core, which is coaxially arranged with the stranding drum 6 and the tensioning plate 501.

[0028] The cantilever bracket 4 is welded or integrally formed on the support plate 2 and located between several drum shafts 3. The tensioning structure 5 and the stranding drum 6 are welded onto it at one time, and the tensioning structure 5 is located at the end of the drum shaft 3. The wires on the drum can pass through the tensioning structure 5 and the stranding drum 6 in sequence to finally form a cable with the wire core. The take-up structure 7 for winding the cable is set on the frame 1 and located at the end of the stranding drum 6 away from the support plate 2.

[0029] In this embodiment, the axially arranged cylindrical shafts 3 on the vertical support plate 2 are used to support the cable drum, replacing the traditional horizontal circumferential arrangement, which effectively reduces the radial dimension of the rotating stranding mechanism. At the same time, the large-span cantilever and multi-layer rotary table are eliminated, and only one set of cantilever brackets 4 is set between the circumferentially distributed cylindrical shafts 3 and fixed to the support plate 2. While ensuring the number of cable drums installed, the cantilever length is shortened and the axial space occupation is reduced. Furthermore, the present invention integrates the tensioning structure 5 and the stranding drum 6 inside the cantilever bracket 4, so that the cable drum wire can be directly entered into the stranding drum 6 for forming after tensioning, eliminating the need for an external independent tensioning mechanism and redundant support components. The overall structure is more compact and efficient, thus solving the technical problems of excessive radial and axial space occupation and redundant machine footprint caused by large-diameter rotary tables, large-span cantilever, multiple sets of cable drums and external tensioning mechanisms in traditional cable forming machines.

[0030] like Figure 3 As shown in the figure, in a specific implementation, one end of the cylinder shaft 3 is rotatably connected to the surface of the support plate 2, and the other end is a suspended end. The suspended end is limited by a detachable blocking block 8. The blocking block 8 can be quickly assembled and fixed by means of threads or buckles, thereby limiting the blocking block 8 and preventing the cylinder from flying out when rotating at high speed, improving the safety of equipment operation. In addition, the detachable structure allows for quick disassembly and assembly of the cylinder, reducing downtime for changing lines and adapting to batch continuous production.

[0031] Specifically: the cylinder shaft 3 is an axially extending support shaft, with its inner end rotating with the support plate 2 and its outer end being a free-hanging end. The hanging end has a threaded hole or a slot. The blocking block 8 is installed by thread tightening or snap-fitting to form an axial stop. The spool is sleeved on the cylinder shaft 3, with the inner side limited by the support plate 2 and the outer side limited by the blocking block 8.

[0032] Meanwhile, when the spool rotates at high speed with the spool shaft 3, compared to the traditional horizontal structure, the wire is axially led out from the end face of the spool. In this process, there is only rotational friction on the end face of the spool. The friction force is very small and stable and will not change abruptly with the remaining amount of wire in the spool. However, when the spool is placed horizontally, the cable needs to be led out from the circumferential side of the spool. During the cable exit process, radial friction will occur with the end face of the spool and the cable layer. When there is less wire left in the spool, the cable layer may "collapse", causing the cable to get stuck or the tension to increase suddenly, directly causing the cable to loosen or break.

[0033] like Figure 3 As shown in the figure, in a specific embodiment, a central gear 9 is rotatably mounted at the center of the support plate 2. Several meshing gears 10 are rotatably arranged on the support plate 2 around the central gear 9, and all meshing gears 10 maintain meshing transmission with the central gear 9. A drive motor is also mounted on the back of the support, and the output end of the drive motor is connected to the central gear 9 to drive the central gear 9 to rotate. Several cylindrical shafts 3 correspond one-to-one with several meshing gears 10. Each cylindrical shaft 3 is coaxially fixed at the center of the corresponding meshing gear 10. When the drive motor drives the central gear 9 to rotate, the central gear 9 synchronously drives all meshing gears 10 to rotate, thereby driving all cylindrical shafts 3 to achieve synchronous rotation. This allows the bobbin to rotate at high speed with the cylindrical shafts 3, reducing the resistance of wire feeding and maintaining uniform and stable feeding tension.

[0034] like Figure 4 and Figure 5As shown in the figure, in a specific embodiment, the tensioning structure 5 includes a tensioning disc 501, which is vertically fixedly welded to the cantilever bracket 4 and coaxially arranged with the support disc 2. The tensioning disc 501 has a plurality of radially arranged grooves 502, the number and position of which correspond one-to-one with the plurality of cylindrical shafts 3. Each groove 502 is equipped with a slider 503 that can slide along the length of the groove 502. Each slider 503 is rotatably mounted with a tensioning wheel 504 through a bearing seat, so that the wire led out of the spool passes around the tensioning wheel 504 and is conveyed forward. When the slider 503 slides along the groove 502 toward the center of the tensioning disc 501, the tensioning wheel 504 moves radially synchronously and pushes the wire, thereby realizing the tension adjustment of the wire. Specifically, the wire passes around the tensioning wheel 504 to form a wrap angle, and the radial movement of the slider 503 can change the length of the wire's path, thereby stabilizing and maintaining the wire tension.

[0035] In this embodiment, the tensioning wheel is radially adjustable with the slider 503 to adapt to the tensioning requirements of wires of different diameters and materials, ensuring that the tension of each wire is consistent before entering the stranding drum 6. The tensioning wheel 504 can rotate on its own, and the wires pass through in a rolling contact manner, effectively reducing friction damage. The overall structure is integrated into the tensioning disc 501, without taking up additional space.

[0036] like Figure 5 As shown, this cable forming machine is also equipped with a guide straightening structure for straightening the conductor. This structure is fixedly bolted to the cantilever bracket 4 and located between the tensioning wheel 504 and the stranding drum 6, so that the conductor on the drum can pass through the tensioning wheel 504, the guide straightening structure and the stranding drum 6 in sequence, realizing continuous processing of tensioning first, straightening then stranding and forming. This solves the problems of bending, warping and swaying of the conductor after it is led out of the drum, which leads to stranding eccentricity. At the same time, it ensures that the tensioning structure 5 is continuously effective and avoids insufficient tension or loosening of the conductor.

[0037] As a specific implementation method, the guide straightening structure includes several guide straightening groups 11, each corresponding to a tensioning wheel 504. Each guide straightening group 11 consists of several straightening wheels 1101 arranged alternately. The conductor passes through the alternately arranged straightening wheels 1101 in sequence and is effectively straightened under repeated forward and reverse bending, eliminating coiling bending and residual stress, and ensuring straightness before entering the stranding drum 6. At the same time, the distance between the guide straightening group 11 and the central axis of the equipment is greater than the distance between the tensioning wheel 504 and the axis, so that the conductor forms a stable tension wrap angle and path difference between the tensioning wheel 504 and the straightening wheel 1101, which cancels out coiling residual stress, realizes automatic straightening, and the overall structure is compact and does not occupy extra space, integrating straightening and guidance to improve the quality of cable formation.

[0038] Specifically, such as Figure 5As shown, there can be three straightening wheels 1101, with the straightening wheels 1101 at both ends located at the bottom and the straightening wheel 1101 in the middle located at the top. The three wheels form a straightening channel for the conductor to pass through, so that the conductor can be straightened after passing through.

[0039] As a parallel implementation method, an integrated guide straightening sleeve can be used, which is fixedly welded between the tensioning wheel 504 and the stranding cylinder 6, and has several sets of arc-shaped guide holes for the wire to pass through. Each set of arc-shaped guide holes corresponds one-to-one with several tensioning wheels 504. Each set of arc-shaped guide holes includes several arc-shaped guide holes arranged linearly. The wall of each arc-shaped guide hole is a smooth arc-shaped transition surface. Thus, when the wire passes through the arc-shaped guide hole, it can be forcibly straightened and oriented along a preset trajectory.

[0040] like Figure 6 and Figure 7 As shown in the figure, in one specific implementation, a mold core 13 is fixedly installed inside the stranding cylinder 6. The mold core 13 has a stranding channel 1301 that runs through it along the central axis for the central main wire core to pass through stably. The mold core 13 also has several spiral wire channels 1302 around the stranding channel 1301. The spiral wire channels 1302 are arranged one-to-one with the cylinder shaft 3 and are all connected to the central stranding channel 1301. Then, under the pulling action of the take-up structure 7, the wires on the cylinder are tensioned and straightened and enter the corresponding spiral wire channels 1302. They converge towards the center along the spiral trajectory and merge with the main wire core in the stranding channel 1301 inside the mold core 13. After being extruded by the stranding cylinder 6, they are formed into a complete cable in one go.

[0041] In this embodiment, the spiral conductor channel 1302 is used to directionally constrain and spirally guide the conductor, so that the conductor is twisted with the central main conductor at a set angle, realizing the conductor and conductor forming in one step, and multiple channels running independently, avoiding the conductors from tangling and interfering with each other, and is more suitable for multi-core composite cables with high requirements for conductor arrangement regularity.

[0042] like Figure 8 As shown, in one specific implementation, the take-up structure 7 includes a take-up drum 701 and a drive motor. The take-up drum 701 is rotatably mounted on the frame 1, and its rotation axis is perpendicular to the axis of the support plate 2, so that the cable enters the take-up drum 701 at a stable angle. The drive motor is fixedly mounted on the frame 1, and its output end is connected to the take-up drum 701 to drive the take-up drum 701 to rotate continuously, so as to evenly and neatly wind and collect the cable formed by the stranded drum 6, thereby realizing continuous automated production of cable formation and winding.

[0043] This embodiment uses a traditional winding structure and does not have an invention point, so it is not described in detail. It mainly achieves stable winding of the cable after stranding and forming, ensuring continuous operation of the production line.

[0044] Working principle: Several spools are fitted onto the axially arranged spool shafts 3 on the support plate 2. They are synchronously driven to rotate by the central gear 9 and the meshing gear 10. First, the wire is smoothly led out from the end face of the spool and passes through the radially adjustable tensioning wheel 504 in sequence. Then, the wire enters the set of vertically interlaced straightening wheels 1101. After continuous forward and reverse bending, the residual stress of the coiling is eliminated, ensuring the straightness of the wire. At the same time, the central main wire core passes through the central through hole 12 of the support plate 2 and the tensioning plate 501 coaxially and enters the twisting channel 1301 of the inner mold core 13 of the twisting spool 6. Multiple wires are directionally spirally conveyed along the spiral wire channel 1302 around the mold core 13. Inside the mold core 13, they converge and twist with the central main wire core, forming a round and regular cable in one go. Finally, the formed cable is continuously pulled and wound by the take-up spool 701 driven by the drive machine. The take-up spool 701 is arranged vertically in the axial direction to avoid bending and twisting of the cable and ensure neat and stable winding.

[0045] The above embodiments are only used to illustrate the technical solutions of this application, and are not intended to limit them. Although this application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this application, and should all be included within the protection scope of this application.
