Description

Technical Field

[0001] This application relates to the field of composite material core processing technology, and in particular to a production line for manufacturing carbon fiber composite material core cables. Background Technology

[0002] Overhead power transmission is a high-quality power transmission method that is low-cost, easy to maintain, and highly adaptable. It is particularly suitable for large-scale, long-distance power transmission and is an indispensable part of power transmission. The reinforcing core of overhead conductors has undergone continuous development, from galvanized steel wire to heat-resistant alloys, high-strength alloys, and finally carbon fiber rods, resulting in continuous improvement in overall performance.

[0003] In the market, metal strips are commonly used to form metal tubes, which are longitudinally wrapped with carbon fibers to form a composite material core. The metal tubes seal the carbon fibers, preventing them from being directly exposed to wind, rain, and sunlight. This can avoid corrosion from the natural environment, delay aging, and extend service life. Therefore, it is necessary to design a production line that combines metal strips with carbon fibers.

[0004] In existing composite material core production lines, burr-free laser welding is often used to improve processing efficiency. Laser welding has high energy density and welding speeds of 10–30 m / min. However, laser welding involves concentrated heat and a small heat-affected zone. During the forming process of the metal strip into a metal tube, it is impossible to ensure that the pressure or friction under the compression of the metal tube is absolutely consistent in all directions and locations. This can lead to twisting of the metal tube, and the weld seam cannot be straightened during traction. Furthermore, the laser welding gun may not be able to weld all the weld seams, resulting in incomplete welds.

[0005] Workers often use plate-shaped components to limit the angle of the weld seam of metal pipes to prevent twisting during extrusion. Before welding, the weld seam needs to be closed, so the position of the plate-shaped component closest to the welding station is particularly important. Workers often use bolts to lock and position the carrier component of the plate-shaped component. However, the carrier component is secured by bolt holes, and the bolt installation itself has installation errors. These errors are small and difficult to identify, causing the plate-shaped component to be unable to effectively align with the welding position. Workers have to adjust the bolt hole position, which is a cumbersome process and reduces the debugging efficiency of the carbon fiber composite core cable manufacturing production line. Summary of the Invention

[0006] To improve the commissioning efficiency of carbon fiber composite core cable manufacturing production lines, this application provides a carbon fiber composite core cable manufacturing production line.

[0007] This application provides a technical solution for a carbon fiber composite core cable manufacturing line: A production line for manufacturing carbon fiber composite core cables includes an unwinding assembly for unwinding carbon fiber and metal strip, a forming mechanism, a traction assembly for pulling the composite core, and a winding assembly for rewinding the composite core. The forming mechanism includes a forming table, a shearing assembly for cutting the metal strip, an extrusion roller assembly, a welding box, and a laser welding gun. The forming table is disposed between the traction assembly and the unwinding assembly. The welding box and the laser welding gun are both mounted on the forming table. A positioning assembly is provided on the forming table. The positioning assembly includes a positioning block, a first positioning plate, and a second positioning plate. Several positioning blocks are provided. The positioning blocks and the first positioning plate are detachably connected to the extrusion roller assembly. A guide block is provided at the bottom of the positioning block. The two sides of the guide block fit with the two sides of the opening of the metal tube. The second positioning plate is vertically mounted on the outer wall of the welding box. The shearing assembly is disposed between the unwinding assembly and the forming table. An installation assembly is provided on the welding box. The installation assembly includes an installation block, a pressure block, a pressure plate, a clamping bolt, a stabilizing clamp, a fixing post, and an ejection spring. A sizing die for limiting the diameter of the metal tube is installed inside the welding box. The axis of the sizing die is aligned with the welding position of the laser welding gun. The mounting block is connected to the welding box and has a height limiting groove. A fixing frame with a clamping groove is connected to the mounting block. Rectangular rods are connected to both ends of the pressure plate. The pressure plate slides vertically within the fixing frame via the rectangular rods. Several sliding rods are connected to the pressure block. A retaining ring is connected to the top of each sliding rod. A pressure spring is sleeved on the sliding rod and is located between the retaining ring and the pressure plate. A V-groove is provided at the bottom of the pressure block. The inner wall of the V-groove extends from top to bottom. The top of the sizing mold is fitted with two fixed posts, both of which are connected to the clamping groove. The stabilizing clamp is connected to the bottom wall of the pressure plate and is located in the clamping groove. A connecting block is connected in the clamping groove. The ejector spring is connected between the connecting block and the inner top wall of the stabilizing clamp. The bottom of the stabilizing clamp is provided with two opposing abutting arc surfaces, which abut against the fixed posts. The second positioning plate is located inside the stabilizing clamp, and its top end abuts against the inner top wall of the height limiting groove. The clamping bolt is threaded onto the fixing frame and abuts against the top wall of the pressure plate.

[0008] By adopting the above technical solution, during processing, the unwinding assembly releases the carbon fiber and metal strip, which are then moved by the traction assembly. During this process, the shearing assembly cuts the metal strip to a specified width. Subsequently, the metal strip is extruded by the extrusion roller group to gradually form a metal tube. At the same time, several carbon fibers enter the unclosed metal tube. The metal tube moves along the sides of the opening against several guide blocks, and the opening of the metal tube gradually narrows. It is then guided by the first positioning plate and by the second positioning plate before entering the welding box. Simultaneously, the laser welding gun is activated to weld the metal tube. Finally, the metal tube is recycled by the winding assembly, thus realizing the processing of the composite material core.

[0009] When installing the second positioning plate, place the second positioning plate into the height limiting groove and let it abut against the top wall of the height limiting groove. Rotate the clamping bolt, the pressure plate descends, which drives the pressure block to descend. The pressure block clamps the sizing mold, the pressure spring is compressed, and at the same time the stabilizing clamp descends, the ejection spring is compressed, and the contact arc surface abuts against the fixing column, so that the two ends of the bottom of the stabilizing clamp close together to clamp the second positioning plate, thus realizing the installation of the second positioning plate.

[0010] By using a sizing die and V-groove to restrict the longitudinal position of the pressure block, the second positioning plate is aligned with the axis of the sizing die. The lateral position of the second positioning plate is restricted by the cooperation of a rectangular rod and a positioning frame. This mechanically limits the installation angle and position of the second positioning plate. This installation method involves fewer steps and is faster, shortening the debugging time of the second positioning plate and improving the debugging efficiency of the carbon fiber composite core cable manufacturing line. Furthermore, the vertical sliding fit between the pressure plate and the pressure block allows the installation assembly to be used with sizing dies of different diameters.

[0011] Optionally, the extrusion roller group includes a first roller group, a second roller group, and a third roller group. The first positioning plate is detachably connected to the third roller group. The second roller group is provided with an adjustment assembly, which includes a mounting plate, an adjusting rod, an adjusting ring, a locking ring, and a locking bolt. Several mounting plates are provided and distributed on both sides of the second roller group. The adjusting rod is provided with a limiting plane, which faces upward. The adjusting rod passes between two mounting plates. The adjusting ring is rotatably connected to one of the mounting plates and is threadedly engaged with the adjusting rod. The locking ring is threadedly engaged with the end of the adjusting rod and abuts against the other mounting plate. The positioning block is sleeved on the adjusting rod. The locking bolt passes through the positioning block and abuts against the limiting plane. The locking bolt is threadedly engaged with the positioning block.

[0012] By adopting the above technical solution, during adjustment, the adjusting rod is inserted between the two mounting plates, and the positioning block is fitted onto the adjusting rod. The position of the positioning block is adjusted, and the locking bolt is threaded onto the positioning block to press against the limiting plane. The rotating ring is rotated to fine-tune the position of the positioning block. Finally, the locking ring is rotated, and the locking ring presses against the mounting plate to increase the friction between the adjusting rod and the adjusting ring, thereby locking the adjusting ring and realizing the installation of the positioning block.

[0013] Optionally, the locking bolt includes a stud, a rotating ring, a fixed lever, and a rotating lever. The stud is threaded onto the positioning block, and an extension post is provided at the bottom end of the stud, which passes through the limiting plane. A limiting groove is formed on the stud. The rotating ring is threaded onto the stud and has a rotating groove. The rotating lever is rotatably connected within the rotating groove, and the fixed lever is connected to the rotating ring. When the stud is rotated, the rotating lever is partially located within the limiting groove. When loosening, the rotating lever disengages from the limiting groove, and the rotating ring abuts against the top wall of the positioning block.

[0014] By adopting the above technical solution, when locking the positioning block, the rotating block is moved to allow part of the rotating block to enter the limiting groove. Then, the fixed block is rotated to make the rotating ring rotate, which drives the stud to rotate until the stud is pressed against the limiting plane and the extension post is inserted into the limiting plane. Then, the rotating block is moved in the opposite direction to disengage the rotating block from the limiting groove. Then, the fixed block is rotated again, and the rotating ring descends until it is pressed against the top wall of the positioning block, thus achieving the effect of preventing the stud from loosening.

[0015] Optionally, the unwinding assembly includes an unwinding frame and a tape unwinding machine. Several rotating rollers are rotatably connected to the unwinding frame, and carbon fiber is wound around the rotating rollers. A tension assembly is provided on the unwinding frame to maintain tension on the carbon fiber. A wire divider is provided on the unwinding frame, and several wire divider holes are opened on the wire divider. The carbon fiber passes through the wire divider holes and extends to the second roller group. The tape unwinding machine is located between the unwinding frame and the shearing assembly, and the metal strip is located on the rotating part of the tape unwinding machine.

[0016] By adopting the above technical solution, during unwinding, the metal strip and several carbon fibers are pulled and moved by the traction component, the carbon fibers are kept under a certain tension by the tension component, and the metal strip is unwound by the unwinding machine.

[0017] Optionally, the shearing assembly includes a shearing table, a limiting wheel group, a first rotating wheel, and a second rotating wheel. The shearing table is disposed on one side of the unwinding assembly, the limiting wheel group is mounted on the shearing table, and a mounting platform is disposed on the shearing table. The first rotating wheel and the second rotating wheel are both rotatably connected to the mounting platform. The first rotating wheel has a conveying ring groove, and the second rotating wheel has two shearing rings. The distance between the outer walls of the two shearing rings is the same as the distance between the two inner walls of the conveying ring groove. A rotating motor is disposed on the mounting platform, and the rotating motor drives the first rotating wheel and the second rotating wheel to rotate through a bevel gear set. The first rotating wheel rotates counterclockwise, and the second rotating wheel rotates clockwise. A recycling assembly for automatically collecting waste material from both sides of the metal strip is disposed on the shearing table.

[0018] By adopting the above technical solution, during shearing, the metal strip passes between the first and second rotating wheels. During this process, the metal strip passes through the limiting wheel group to ensure that the metal strip is located between the first and second rotating wheels. The rotating motor is started to make the first and second rotating wheels rotate. The moving metal strip is cut by the shearing ring on both sides, and the remaining material continues to move through the conveying ring groove. The waste on both sides of the metal strip is continuously recycled by the recycling component, thus achieving the effect of shearing the metal strip.

[0019] Optionally, the recycling assembly includes a first guide wheel, a limiting channel, a second guide wheel, a third guide wheel, a collecting wheel, and a collecting motor. The first guide wheel, the second guide wheel, and the collecting wheel are all rotatably connected to the shearing table. The limiting channel is connected to the shearing table and communicates between the first guide wheel and the second guide wheel. The collecting motor is installed inside the shearing table and is coaxially connected to the collecting wheel. The shearing table is provided with a uniform distribution assembly that evenly distributes the metal strip waste onto the collecting wheel. The third guide wheel is connected to the output end of the uniform distribution assembly.

[0020] By adopting the above technical solution, during recycling, the collection motor is started, the metal strip waste is pulled, and passes through the first guide wheel, the limiting channel, the second guide wheel and the third guide wheel in sequence, and finally enters the collection wheel. The metal strip waste is then dispersed to various positions of the collection wheel by the uniform distribution component, thereby achieving the effect of automatic recycling of metal strip waste.

[0021] Optionally, the uniform distribution assembly includes a drive motor, a reciprocating lead screw, a moving table, and a moving rod. The reciprocating lead screw is rotatably connected inside the shearing table. The drive motor is installed inside the shearing table and connected to the reciprocating lead screw via a sprocket and chain assembly. The moving rod is slidably fitted onto the shearing table via a sliding bearing. Two third guide wheels are provided, and the third guide wheels are rotatably connected to the ends of the moving rod. The moving table is connected to the moving rod and threadedly engaged with the reciprocating lead screw.

[0022] By adopting the above technical solution, when the material is evenly distributed, the drive motor is started to make the reciprocating screw rotate. Due to the cooperation between the moving rod and the shearing table, the moving table moves back and forth, which drives the moving rod to move back and forth, and the third guide wheel to move back and forth, thus achieving the effect of evenly distributing the metal strip waste on the collecting wheel.

[0023] Optionally, a grease injection cylinder is installed on the molding table. The grease injection cylinder is located between the second roller group and the first roller group. The surface of the grease injection cylinder has a grease injection notch. One end of the grease injection cylinder is provided with an extension tube. The outlet end of the extension tube is located inside the metal tube. The other end of the grease injection cylinder is provided with a guide tube. Carbon fiber enters the metal tube in sequence through the guide tube, the grease injection cylinder and the extension tube. The inside of the grease injection cylinder is filled with resin.

[0024] By adopting the above technical solution, all carbon fibers converge in the guide tube during movement. The resin injection cylinder is filled with resin, which is carried away by the carbon fibers and converges in the metal tube, thus automatically filling the metal tube with resin. The resin and carbon fibers form an integral mandrel, which easily and tightly bonds to the inner wall of the metal tube. This allows the carbon fibers, resin, and metal tube to solidify into a synergistic, temperature-resistant, corrosion-resistant, and dimensionally stable whole, improving the overall quality and service life of the composite core.

[0025] Optionally, it also includes a stranding member for stranding the composite core, a curing assembly, a traction member for pulling the composite core cable, a meter counter for counting the length of the composite core cable, and a winding machine for winding the composite core cable. The curing assembly includes a first curing section, a second curing section, and a cooling section. The first curing section and the second curing section are used to heat the composite core cable, and the cooling section is used to cool the composite core cable.

[0026] By adopting the above technical solution, during processing, a winding wheel containing composite material cores is installed on a stranding member. Several composite material cores are integrated into a composite material core cable through the stranding member. The composite material core cable passes through the first curing section and the second curing section in sequence, which raises the temperature of the composite material core cable. The metal tube on the surface of the composite material core cable is pulled, and the internal stress is released. When passing through the cooling section, the internal resin solidifies to further shape the composite material core cable. The composite material core cable is moved by the traction member, and the length of the composite material core cable is calculated by the meter counter. Finally, the composite material core cable is wound up by the winding machine, thus realizing the processing of the composite material core cable.

[0027] Optionally, the traction component is a tracked traction machine. Both the inlet and outlet ends of the traction component are equipped with limiting roller sets. Each limiting roller set includes a horizontal roller and two vertical rollers. A connecting frame is connected to the traction component. One end of each horizontal roller is mounted on the connecting frame. A moving component is mounted on the connecting frame. The moving component includes a moving seat, a pull rope, a compression spring, a steering wheel, a moving column, a drive ring, and a rotation limiting block. A sliding plate is connected to the connecting frame. The moving seat is slidably fitted onto the sliding plate. The vertical rollers are rotatably connected to the moving seat. Two pull ropes are provided, one end of which is connected to the moving seat. The system is connected to the base, with the movable column connected between the other ends of the two pull ropes. The steering wheel is rotatably connected to the connecting frame, and the pull ropes are wound around the steering wheel. The compression spring is installed between the two movable bases. The connecting frame has a movable hole, and the rotation limiting block is connected to the inner wall of the movable hole. The movable column passes through the movable hole, and the surface of the movable column has a movable groove. The rotation limiting block is slidably fitted in the movable groove. The drive ring is rotatably connected to the connecting frame and threadedly engaged with the movable column. During movement, the composite material core cable passes between the horizontal roller and the two vertical rollers.

[0028] By adopting the above technical solution, the limiting roller assembly is used to assist in limiting the movement direction of the composite core cable, and the moving component is used to assist in adjusting the distance between the two vertical rollers to accommodate composite core cables of various diameters. During adjustment, rotating the drive ring causes the moving column to move from its original state through the cooperation of the limiting block and the moving groove with the drive ring and the moving column. This moves the two pull ropes, causing the two moving seats to move simultaneously toward the steering wheel position. The compression spring is compressed to shorten the distance between the two vertical rollers. Reverse rotation of the drive ring causes the moving seats to move in the opposite direction under the force of the compression spring, thereby increasing the distance between the two vertical rollers.

[0029] In summary, this application includes at least one of the following beneficial technical effects: During processing, the unwinding assembly releases the carbon fiber and metal strip, which is then moved by the traction assembly. During this process, the shearing assembly cuts the metal strip to a specified width. The metal strip then passes through the first, second, and third roller groups in sequence, gradually forming a metal tube. Before the second roller group, several carbon fibers enter the unclosed metal tube. Simultaneously, the metal tube moves along the sides of its opening against several guide blocks. As it passes the third roller group, the opening of the metal tube gradually narrows and is guided by the first positioning plate. Before entering the welding box, it is guided by the second positioning plate. At the same time, the laser welding gun is activated to weld the metal tube. Finally, the metal tube is retrieved by the winding assembly, completing the processing of the composite material core. When installing the second positioning plate, it is placed within the height limit. The groove, and abutting against the top wall of the height limiting groove, rotate the clamping bolt, the pressure plate descends, driving the pressure block to descend, the pressure block presses against the sizing mold, the pressure spring is compressed, at the same time the stabilizing clamp descends, the ejection spring is compressed, the abutting arc surface abuts against the fixed column, so that the two ends of the bottom of the stabilizing clamp close to clamp the second positioning plate, thus realizing the installation of the second positioning plate; by setting the sizing mold and V-groove, the longitudinal position of the pressure block is limited, so that the second positioning plate is aligned with the axis of the sizing mold; by the cooperation of the rectangular rod and the positioning frame, the lateral position of the second positioning plate is limited, thus mechanically limiting the installation angle and position of the second positioning plate. This installation method has fewer steps and is faster, shortening the debugging time of the second positioning plate and improving the debugging efficiency of the carbon fiber composite core cable production line; When locking the positioning block, move the rotating block to make the rotating block part enter the limiting groove, then rotate the fixed block to make the rotating ring rotate, which drives the stud to rotate until the stud is pressed against the limiting plane and the extension post is inserted into the limiting plane. Then move the rotating block in the opposite direction to make the rotating block disengage from the limiting groove. Then rotate the fixed block to make the rotating ring descend until it is pressed against the top wall of the positioning block, thus achieving the effect of preventing the stud from loosening. During processing, a winding wheel containing composite material cores is installed on a stranding member. Several composite material cores are integrated into a composite material core cable through the stranding member. The composite material core cable passes through the first curing section and the second curing section in sequence, which raises the temperature of the composite material core cable. The metal tube on the surface of the composite material core cable is pulled, and the internal stress is released. When passing through the cooling section, the internal resin solidifies to further shape the composite material core cable. The composite material core cable is moved by the traction member, and the length of the composite material core cable is calculated by the meter counter. Finally, the composite material core cable is wound up by the winding machine, thus realizing the processing of the composite material core cable. Attached Figure Description

[0050] The following is in conjunction with the appendix Figures 1-19 This application will be described in further detail.

[0051] This application discloses a production line for manufacturing carbon fiber composite core cables. (Refer to...) Figure 1 The carbon fiber composite core cable manufacturing line includes an unwinding assembly 1 for unwinding carbon fiber and metal strip, a forming mechanism 2 for extruding the metal strip into a metal tube, a traction assembly 3 for moving the composite core, and a winding assembly 4 for winding the composite core.

[0052] The traction component 3 pulls the carbon fiber and metal strip to move, the forming mechanism 2 gradually extrudes the metal strip into a metal tube, and carbon fiber is filled into the metal tube during this process. Finally, the weld of the metal tube is welded, and the composite material core is finally wound up by the winding component 4, thus realizing the processing of the composite material core.

[0053] Reference Figure 1 and Figure 2 The unwinding assembly 1 includes an unwinding frame 11 and a tape unwinding machine 12. Several rollers 111 are mounted on the unwinding frame 11 via bearing seats, and carbon fiber is sleeved on each roller 111. A tension assembly 13 is mounted on the unwinding frame 11, comprising a mounting post 131, a friction wheel 132, a friction belt 133, a tension spring 134, and a fixing block 135. Several sliding grooves are formed on the unwinding frame 11, and T-blocks slide within these grooves. The mounting post 131 and the fixing block 135 are threaded onto their respective T-blocks. The friction wheel 132 is coaxially connected to the rollers 111. The friction belt 133 is a rubber belt, with one end sleeved on the mounting post 131 and wound around the friction wheel 132. One end of the tension spring 134 is mounted on the fixing block 135, and the other end is mounted on the other end of the friction belt 133. Several wire dividers are fixedly connected to the wire feeding frame 11, and several wire dividing holes are opened on the wire dividers. The tape feeding machine 12 is set on one side of the wire feeding frame 11, and the metal tape is wound around the rotating part of the tape feeding machine 12. The metal tape is an aluminum alloy tape.

[0054] During unwinding, the carbon fiber and metal strip are moved by the traction assembly 3. The carbon fiber passes through the dividing hole, causing the rotating roller 111 to rotate. The force of the tension spring 134 pulls the friction belt 133, making the friction belt 133 stick tightly to the surface of the friction wheel 132, so that the rotating roller 111 will not rotate due to inertia, ensuring a certain tension of the carbon fiber. The metal strip is fed by the unwinding machine 12.

[0055] Reference Figure 1 , Figure 3 and Figure 4 The forming mechanism 2 includes a forming table 21, a shearing assembly 22, an extrusion roller group 23, a welding box 24, and a laser welding gun 25. The extrusion roller group 23 includes a first roller group 2311, a second roller group 232, and a third roller group 233.

[0056] Reference Figure 4 , Figure 5 and Figure 6 The shearing assembly 22 includes a shearing table 221, a limiting wheel set 222, a first rotating wheel 223, and a second rotating wheel 224. The shearing table 221 is located on the side of the tape feeder 12 away from the feed frame 11, and the limiting wheel set 222 is mounted on the shearing table 221.

[0059] When shearing the metal strip, the moving metal strip enters between the first rotating wheel 223 and the second rotating wheel 224 through the limiting wheel set 222. The metal strip is squeezed and sheared by two shearing rings 2241 on both sides. The excess material moves through the conveying ring groove 2231, while the waste material on both sides is restricted by the first guide wheel 51, the limiting channel 52, the second guide wheel 53 and the third guide wheel 54 and enters the collecting wheel 55.

The installation block 91 is bolted to the side wall of the welding box 24 near the third roller group 233. A fixing frame 911 is fixedly connected to the installation block 91. The installation block 91 also has a clamping groove 912 and a height limiting groove 913.

The three guide blocks 711, the first positioning plate 72 and the second positioning plate 73 are all in a straight line.

[0068] When installing the positioning block 71, first pass the adjusting rod 82 through another mounting plate 81, and then place the positioning plate on the adjusting rod 82. Next, pass one end of the adjusting rod 82 through the adjusting ring 83, and rotate the adjusting ring 83. Then, move the rotating paddle 854 so that part of the rotating paddle 854 enters the limiting groove 8511. Move the fixing paddle 853 to drive the stud 851 to rotate until the stud 851 presses against the limiting plane 821. Then, move the rotating paddle 854 in the opposite direction to disengage it from the limiting groove 8511. Move the rotating ring 852 until it presses against the positioning block 71 to lock it. Then, rotate the adjusting ring 83 to move the adjusting rod 82 to fine-tune the position of the positioning block 71. Finally, rotate the locking ring 84 to lock the adjusting rod 82, thus completing the installation of the positioning block 71.

[0069] During the molding of the metal tube, the metal strip passes through the first roller group 231, the second roller group 232, and the third roller group 233 in sequence. During this process, the metal strip is gradually squeezed into a metal tube. In this process, carbon fiber passes through the resin injection cylinder 211 and carries the resin into the metal tube. At this time, the guide block 711 restricts the opening of the metal tube. When it reaches the third roller group 233, the opening of the metal tube gradually closes and is restricted by the first positioning plate 72 and the second positioning plate 73 in sequence. After entering the welding box 24, the diameter is first constrained by the sizing die 244, and then the welding position is defined by the positioning roller 245. At the same time, the laser welding gun 25 is activated to weld the weld seam of the metal tube. After the metal tube is welded, it passes through the welding area 243 and is cooled by the cooling gas to realize the molding of the composite material core.

[0070] Reference Figure 1 , Figure 14 and Figure 15 The traction assembly 3 includes a clamp-type traction machine 31 and a tracked traction machine 32. Two clamp-type traction machines 31 are provided. Each clamp-type traction machine 31 includes a housing 311, a traction motor 312, a waist-shaped rail 313, a chain plate 314, and a clamping block 315. The housing 311 is located on the side of the forming table 21 away from the shearing table 221. The waist-shaped rail 313 is fixedly connected inside the housing 311. The waist-shaped rail 313 is provided with two limiting ring grooves. The limiting ring grooves are provided with clamping parts 3131 and releasing parts 3132. The clamping parts 3131 are located in the flat area at the top of the limiting ring grooves. The distance between the two clamping parts 3131 is less than the distance between the two releasing parts 3132.

[0071] Reference Figure 1 , Figure 14 and Figure 15 The traction motor 312 is mounted on the housing 311. A sprocket and chain assembly is provided between the traction motor 312 and the housing 311. Several chain plates 314 are provided, all mounted on the sprocket and chain assembly, and the chain plates 314 move along the waist-shaped rail 313.

The tracked traction machine 32 is located on the side of the clamp-type traction machine 31 away from the forming table 21.

[0072] During traction, the metal pipe passes through the clamping part 3131, the traction motor 312 is started, and the chain plate 314 is moved through the sprocket and chain group, causing the clamping block 315 to move. When the drive wheel 3151 enters the clamping part 3131 from the loosening part 3132, the two clamping blocks 315 move towards each other to clamp the metal pipe and move it, thus initially driving the metal pipe to move. Subsequently, the metal pipe enters the tracked traction machine, and the two tracks press the metal pipe to achieve secondary traction of the metal pipe.

[0073] Reference Figure 16The winding assembly 4 includes a winding frame 41, a winding wheel 42, a winding motor 43, and hydraulic cylinders 44. A drive head 411 and a clamping head 441 are rotatably connected to the winding frame 41. Both the drive head 411 and the clamping head 441 have conical surfaces. The winding motor 43 is mounted on the winding frame 41 and connected to the drive head 411 via a transmission belt. Two hydraulic cylinders 44 are provided, both mounted on the winding frame 41. A sliding rod is connected to the clamping head 441, and a sliding cylinder 412 is connected to the winding frame 41. The sliding rod is slidably fitted within the sliding cylinder 412. A push plate 442 is connected between the output shafts of the two hydraulic cylinders 44. The clamping head 441 is mounted on the push plate 442, and the winding wheel 42 abuts against the drive head 411 and the clamping head 441. When the winding wheel 42 is working, a gap remains between it and the ground.

[0074] During winding, the winding motor 43 is started, and the drive head 411 rotates via belt drive, causing the winding wheel 42 to rotate, thus achieving the effect of winding the composite material core around the winding wheel 42. When disassembling the winding wheel 42, two hydraulic cylinders 44 are started, causing the push plate 442 to move, which in turn moves the clamping head 441 to disengage from the winding wheel 42, allowing the winding wheel 42 to fall down. During installation, the winding wheel 42 is rolled between the clamping head 441 and the drive head 411, and the hydraulic cylinders 44 are started. The compression of the clamping head 441 and the drive head 411 causes the winding wheel 42 to lift off the ground.

[0075] Reference Figure 17 The carbon fiber composite core cable manufacturing line also includes a stranding unit 101, a curing assembly 102, a traction unit 103, a meter counter 105, and a winding machine 106. The stranding unit 101 is a frame stranding machine; the winding reels 42 after winding are mounted on the stranding unit 101, and the stranding unit 101 strands the composite cores on several winding reels 42 into a single composite core cable. A paralleling die is provided inside the stranding unit 101, which, through the paralleling die, strands the composite core cable into a specified shape.

[0076] Reference Figure 17 The curing component 102 includes a first curing section 1021, a second curing section 1022, and a cooling section 1023. High-frequency alternating current is passed into the induction coil inside the first curing section 1021 and the second curing section 1022 to generate an alternating magnetic field inside. Under the action of this magnetic field, the metal tube on the surface of the composite material core cable generates an induced current and releases a large amount of heat energy instantly to increase the temperature of the surface of the composite material core cable.

[0077] Reference Figure 17The first curing section 1021 is used to preheat and raise the temperature of the composite core cable, ensuring this temperature does not exceed the upper limit of the resin's curing temperature. The second curing section 1022 is used for temperature-controlled composite core cable curing, ensuring its temperature does not exceed the resin's minimum carbonization temperature. The cooling section 1023 contains a hollow metal tube and a fan, with the fan outlet connected to the inside of the metal tube. The composite core cable passes through the hollow metal tube, and the fan blows cold air into the metal tube to rapidly cool the composite core cable.

[0078] Reference Figure 17 and Figure 18 The traction component 103 is a tracked traction machine 32. Both the inlet and outlet ends of the traction component 103 are equipped with limiting roller sets, which include a horizontal roller 1032 and two vertical rollers 1031. A connecting frame is bolted to the traction component 103, and one end of the horizontal roller 1032 is bolted to the connecting frame. A moving assembly 104 is mounted on the connecting frame, which includes a moving seat 1041, a pull rope 1042, a compression spring 1043, a steering wheel 1044, a moving column 1045, a drive ring 1046, and a rotation limiting block 1047. A sliding plate is welded to the connecting frame, and the moving seat 1041 slides on the sliding plate. The vertical rollers 1031 are rotatably connected to the moving seat 1041. The compression spring 1043 is installed between the two moving seats 1041.

[0079] Reference Figure 18 and Figure 19 Two steering wheels 1044 are provided, both rotatably connected to the connecting frame. One end of the pull rope 1042 is fixedly connected to the movable seat 1041, and the other end is wound around the steering wheel 1044. The movable column 1045 is fixedly connected between the other ends of the two pull ropes 1042. The connecting frame has a movable hole, and the rotation limiting block 1047 is fixedly connected in the movable hole. The movable column 1045 passes through the movable hole, and a movable groove is opened on the surface of the movable column 1045, in which the rotation limiting block 1047 slides. The drive ring 1046 is rotatably connected to the connecting frame and threadedly engaged with the movable column 1045.

[0080] When adjusting the distance between the two vertical rollers 1031, the drive ring 1046 is rotated. Through the cooperation between the rotation limit block 1047 and the moving groove, and the cooperation between the drive ring 1046 and the moving column 1045, the moving column 1045 moves to its original state, driving the two pull ropes 1042 to move, causing the two moving seats 1041 to move closer to the center. The compression spring 1043 is compressed to reduce the distance between the two vertical rollers 1031. When conveying cables with a larger diameter, the drive ring 1046 is rotated in the opposite direction. The moving seat 1041 moves in the opposite direction under the force of the compression spring 1043 to increase the distance between the two vertical rollers 1031.

[0081] Reference Figure 17The meter counter 105 is located at the end of the traction member 103 away from the curing component 102. The composite core cable passes through the meter counter 105, which is used to calculate the length of the composite core cable. The winding machine 106 is located at the outlet end of the meter counter 105. The winding machine 106 is an automatic winding machine used to automatically wind up the composite core cable.

[0082] The implementation principle of a carbon fiber composite core cable manufacturing line according to an embodiment of this application is as follows: During processing, the traction motor 312 is started, driving the chain plate 314 to move. The two clamping blocks 315 move towards each other under the influence of the clamping part 3131 to clamp the metal tube. This is combined with the crawler-type traction machine 32 to achieve secondary traction. The winding motor 43 is started, causing the winding wheel 42 to rotate. The composite core is wound around the winding wheel 42, thereby pulling the metal strip and carbon fiber to move. The metal strip is released from the unwinding machine 12 and then enters between the first rotating wheel 223 and the second rotating wheel 224 through the limiting roller group. After being sheared by the shearing ring 2241, the remaining material continues to move through the conveying ring groove 2231. The waste on both sides enters the collecting wheel 55 through the first guide wheel 51, the limiting channel 52, the second guide wheel 53, and the third guide wheel 54. During this period, the drive motor 61 is started, the reciprocating screw 62 rotates, the moving table 63 moves back and forth, driving the moving rod 64 to move back and forth, so that the waste is evenly distributed on the collecting wheel 55. The excess material passes sequentially through the first roller group 231, the second roller group 232, the third roller group 233, and the welding box 24. The first roller group 231, the second roller group 232, and the third roller group 233 gradually extrude the metal strip into a metal tube. During this process, carbon fiber enters the resin injection cylinder 211 through the dividing plate and carries the resin into the open metal tube. The laser welding gun 25 is activated to quickly weld the weld seam of the metal tube. After the metal tube and the internal resin are cooled by nitrogen, they enter the clamp-type traction machine 31. The traction motor 312 is activated, the chain plate 314 moves, driving the clamping block 315 to move. The drive wheel 3151 enters the clamping part 3131 from the loosening part 3132. The clamping block 315 moves with the drive wheel 3151 until the metal tube is clamped and moved, thus initially tractioning the composite material core. The composite material core enters the tracked traction machine for secondary traction of the composite material core. Finally, the winding motor 43 is activated, the drive head 411 rotates, and the composite material core is wound onto the winding wheel 42, realizing the processing of a single composite material core.

[0083] After winding, the winding wheel 42 is installed on the stranding member 101. The stranding member 101 twists multiple composite cores into a single composite core cable. The composite core cable then passes through the first curing section 1021, the second curing section 1022, and the cooling section 1023 in sequence. During this process, the composite core cable is heated, kept at a constant temperature, and cooled. Then, the composite core cable is pulled and moved by the tracked traction machine 32. The composite core cable passes through the meter counter 105 and the length of the composite core cable is recorded. Finally, the winding machine 106 winds up the composite core cable, thus realizing the processing of the composite core cable.

[0084] By using the sizing mold 244 and the V-groove, the longitudinal position of the pressure block 92 is restricted, aligning the second positioning plate 73 with the axis of the sizing mold 244. The lateral position of the second positioning plate 73 is restricted by the cooperation of the rectangular rod and the positioning frame. This mechanically limits the installation angle and position of the second positioning plate 73. This installation method involves fewer steps and is faster, shortening the debugging time of the second positioning plate 73 and improving the debugging efficiency of the carbon fiber composite core cable manufacturing line. Simultaneously, the vertical sliding fit between the pressure plate 93 and the pressure block 92 allows the mounting assembly 9 to be used with sizing molds 244 of different diameters.

[0085] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
