[0002] In the field of cable manufacturing, copper wire straightening is a key process, and its processing quality directly determines the electrical performance and mechanical strength of the cable. Traditional copper wire straightening equipment generally has problems such as poor parameter adaptability, insufficient temperature control and low straightening accuracy: on the one hand, most equipment adopts a fixed roller spacing and pressure design. When facing copper wires of different diameters and hardness, it is necessary to manually replace the rollers or adjust the parameters, which is not only time-consuming and labor-intensive, but also easy to cause copper wire breakage or surface scratches due to improper parameter matching; on the other hand, during the high-speed straightening process, the heat generated by plastic deformation and friction is difficult to dissipate effectively, which often causes annealing and softening of the copper wire, reducing the material strength and conductivity; in addition, the shaping mechanism of traditional equipment is mostly a static structure, which cannot dynamically adjust the straightening force according to the real-time status of the copper wire, resulting in poor straightening effect of complex bends or special-shaped copper wires.

[0014] Compared with the prior art, the advantages and positive effects of the present invention are

[0015] 1. The present invention proposes a copper wire straightening device for cable processing, in which a first motor drives a rotating rod, which is driven by a bevel gear to rotate the rotating rod. When the speed increases, the centrifugal force of the counterweight ball drives the sensing component to trigger the control system, accurately adjust the position of the rotating rod, and thus change the spacing between the lower rollers. This design has achieved a breakthrough in adaptive matching between the copper wire transportation speed and the straightening parameters. Compared with traditional fixed-spacing equipment, it can avoid the copper wire from breaking due to excessive back-bending during high-speed operation. At the same time, by expanding the roller spacing, the heat dissipation area is increased to prevent the copper wire from overheating and annealing due to increased speed. Regardless of the specifications of the copper wire being processed, the equipment can always maintain stable and efficient straightening performance, significantly improve production efficiency, reduce scrap rate, and reduce material waste and downtime and debugging time caused by equipment parameter mismatch.

[0016] 2. The present invention proposes a copper wire straightening device for cable processing, which realizes high-precision straightening of multi-material copper wires through the precise design of the shaping mechanism. The second motor drives the cam to rotate, and its wavy curve cooperates with the spring reset structure to enable the shaping wheel to apply periodic pressure to the copper wire, effectively eliminating various bending defects; at the same time, the first cylinder can flexibly adjust the axial position of the cam to adapt to copper wires of different hardness. Compared with traditional fixed pressure straightening, this dynamic shaping solution can intelligently adapt to the hardness differences of copper wires. For hard copper wires, it can avoid breakage caused by excessive pressure; for soft copper wires, it prevents surface damage caused by excessive shaping. There is no need for manual frequent changes of equipment parameters, and the optimal straightening force can be automatically matched, which greatly improves the versatility of the equipment, meets the cable processing industry's production needs for diversified products, effectively reduces the cost of manual intervention, and improves the degree of production automation and product quality stability.

[0017] 3. The present invention proposes a copper wire straightening device for cable processing, which ensures high precision and stability of the straightening process through the precise coordinated structure of the spacing adjustment and shaping mechanism. The connecting rod drives the connecting plate to slide, and cooperates with the synchronous movement of the lifting rod in the vertical groove, so that the shaping wheel is always accurately positioned at the center line position of the two adjacent lower rollers. Compared with the traditional separate adjustment structure, this design can avoid the position offset of the shaping wheel caused by adjusting the spacing between the lower rollers. No matter how the spacing between the lower rollers changes, the shaping wheel can maintain a uniform distribution of pressure on the copper wire, eliminating the problem of local over-straightening or insufficient straightening. It is particularly suitable for precision cable production with strict surface quality requirements. It can effectively improve product consistency, reduce rework and scrap caused by straightening deviation, and ensure high-quality output of cable products.

[0018] 4. The present invention proposes a copper wire straightening device for cable processing. Its rotary cooling mechanism provides efficient heat dissipation for the copper wire. The support rod drives the blow pipe to rotate through the bevel gear transmission, generating a spiral airflow that evenly covers the surface of the copper wire. Compared with traditional fixed blowing cooling, this design significantly enhances the uniformity and effectiveness of heat dissipation, can quickly take away the heat generated by plastic deformation and friction during the straightening process, and completely solve the problem of copper wire softening caused by heat generation during straightening. Even under continuous high-speed production conditions, it can continuously and stably protect the copper wire material performance. It is especially suitable for the processing of special cables that are sensitive to temperature, such as tinned copper wire, enameled wire, etc., and can avoid the decline in conductivity or damage to the coating due to the annealing effect, effectively improve product quality, extend the continuous operation time of the equipment, and enhance the company's competitiveness in the high-end cable market.

DETAILED DESCRIPTION

[0029] In order to more clearly understand the above-mentioned objects, features and advantages of the present invention, the present invention is further described below in conjunction with the accompanying drawings and embodiments. It should be noted that, in the absence of conflict, the embodiments of the present application and the features therein can be combined with each other.

[0030] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways than those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0031] like Figures 1-9 As shown, a copper wire straightening device for cable processing includes a frame 1, and a spacing adjustment mechanism 2 is provided inside the frame 1. The spacing adjustment mechanism 2 includes a rotating rod 201, a connecting rod 202 and a lifting rod 203. The outer surface of the rotating rod 201 is fixedly connected to a first gear 204, the outer surface of the connecting rod 202 is fixedly connected to a second gear 205, the second gear 205 is meshed with the first gear 204, and a rotating plate 206 is rotatably connected between the rotating rod 201 and the adjacent connecting rod 202 through a bearing. The outer surface of the rotating rod 201 is fixedly connected to a lower roller 207, and the outer surface of the connecting rod 202 is rotatably connected to a connecting frame 208 through a bearing. The inner surface of the frame 1 is fixedly connected to a supporting frame 209, and the lower surface of the supporting frame 209 is slidably connected to a connecting plate 210. The connecting plate 210 is slidably connected to the connecting frame 208. The outer surfaces of the connecting plate 210 and the connecting frame 208 are provided with vertical grooves 211, and the lifting rod 203 is slidably connected to the vertical groove 211.

[0032] The effect is that the first gear 204 on the outer surface of the rotating rod 201 forms an engaged transmission with the second gear 205 of the connecting rod 202, so that the two rotate in opposite directions, and then drive the next first gear 204 to rotate, so that all the rotating rods 201 rotate in the same direction, all the lower rollers 207 rotate synchronously, and the lower end of the connecting frame 208 slides with the connecting plate 210, and the connecting plate 210 moves horizontally along the slide groove on the lower surface of the support frame 209, wherein the connecting rod 202 drives the connecting plate 210 to move through the connecting frame 208, and the connecting plate 210 always slides along the bottom of the support frame 209 and remains vertical. When the spacing of the lower rollers 207 is adjusted, the connecting rod 202 will undergo vertical displacement. At this time, the connecting frame 208 can slide with the connecting plate 210, and the set lifting rod 203 always slides inside the vertical slot 211, so that it can be adjusted synchronously with the position of the connecting rod 202.

[0033] like Figures 1-9As shown, the interior of the frame 1 is also provided with a shaping mechanism 3, which includes a lifting frame 301, the lifting frame 301 is rotatably connected to the lifting rod 203 through a bearing, the outer surface of the lifting rod 203 is rotatably connected to the shaping wheel 302, the upper surface of the lifting frame 301 is fixedly connected to the limiting rod 303, the outer surface of the support frame 209 is provided with a limiting groove 304, the inner surface of the limiting groove 304 is slidably connected to the sliding frame 305, the sliding frame 305 is slidably connected to the limiting rod 303, the upper surface of the lifting frame 301 is fixedly connected to the block 306, the inner surface of the frame 1 is rotatably connected to the support rod 307 through a bearing, the support rod 30 The outer surface of 7 is slidably connected with a cam 308, and the abutment block 306 abuts against the cam 308. A spring 309 is fixedly connected between the sliding frame 305 and the lifting frame 301. The inner surface of the cam 308 is fixedly connected with the limiting block 6. The outer surface of the support rod 307 is provided with a limiting slide groove 7. The limiting block 6 is slidably connected to the limiting slide groove 7. The lower surface of the sliding frame 305 is fixedly connected with the mounting frame 8. The outer surface of the mounting frame 8 is installed with a first cylinder 9. The output end of the first cylinder 9 is fixedly connected with a sliding plate 10. The sliding plate 10 is rotatably connected to the cam 308 through a bearing. The mounting frame 8 and the sliding plate 10 are movably connected to the support rod 307.

[0034] The effect is that when the support rod 307 drives the cam 308 to rotate, the wavy curve on the outer periphery of the cam 308 continuously abuts against the block 306 of the lifting frame 301, converting the rotational motion into a reciprocating motion of the lifting frame 301 along the limit rod 303. The lifting frame 301 is connected to the lifting rod 203 through a bearing, and the shaping wheel 302 at its lower end applies periodic pressure to the copper wire to eliminate residual bending. The spring 309 between the sliding frame 305 and the lifting frame 301 provides a reset force to ensure that the cam 308 can always be in contact with the block 306 on the lifting frame 301. The first cylinder 9 on the mounting frame 8 can drive the sliding plate 10 to move axially along the support rod 307. Through the cooperation of the limit block 6 and the limit slide groove 7, the axial position of the cam 308 on the support rod 307 is adjusted, and the effective radius of the action curve of the cam 308 is changed, thereby adapting to the different shaping requirements of hard and soft copper wires, avoiding the hard material from breaking due to excessive pressure or the soft material from deforming due to excessive shaping.

[0035] like Figures 1-9 As shown, a cooling mechanism 4 is also provided inside the frame 1, and the cooling mechanism 4 includes a blowing pipe 401 and a mounting rod 402. The outer surfaces of the blowing pipe 401 and the support rod 307 are fixedly connected with a first bevel gear 403, and the upper surface and lower surface of the mounting rod 402 are fixedly connected with a second bevel gear 404. The two first bevel gears 403 are respectively engaged with the adjacent second bevel gears 404. The support frame 209 and the surface of the frame 1 are fixedly connected with a positioning frame 405. The blowing pipe 401, the mounting rod 402 and the support rod 307 are respectively rotatably connected to the positioning frame 405 through bearings, and the blowing pipe 401 is rotatably connected to the frame 1 through a bearing.

[0036] The effect is that when the support rod 307 rotates, the first bevel gear 403 at its outer end engages with the second bevel gear 404 at the upper end of the mounting rod 402, driving the mounting rod 402 to rotate, and the second bevel gear 404 at the lower end of the mounting rod 402 drives the first bevel gear 403 at the outer end of the blowing pipe 401, so that the blowing pipe 401 rotates at a uniform speed around the axis. The air holes evenly distributed on the outer wall of the blowing pipe 401 form a spiral airflow during the rotation process, which can cover the surface of the copper wire more evenly than a fixed air blower, and take away the plasticity caused during the straightening process. The heat generated by deformation and friction effectively controls the temperature of the copper wire below the critical annealing temperature. During actual operation, the copper wire enters the equipment from the entrance and first passes through the lower roller 207 group of the spacing adjustment mechanism 2. According to the real-time adjustment of the control mechanism 5, the roller spacing automatically matches the copper wire specifications and running speed. The shaping wheel 302 is driven by the cam 308 to perform surface finishing on the copper wire to eliminate wave bends and spiral bends. During the whole process, the rotating blow pipe 401 of the cooling mechanism 4 continuously sprays cooling air to prevent the copper wire from softening due to temperature rise.

[0037] like Figures 1-9 As shown, the interior of the frame 1 is also provided with a control mechanism 5, which includes a rotating rod 501, the inner surface of the rotating rod 501 is slidably connected to a rectangular rod, the outer surface of the rectangular rod is fixedly connected to a third bevel gear 502, the outer surface of the rotating rod 201 is fixedly connected to a fourth bevel gear 503, the fourth bevel gear 503 is meshed with the third bevel gear 502, one end of the rotating rod 501 is rotatably connected to a positioning column 504 through a bearing, the outer surface of the rotating rod 501 is slidably connected to a sliding block 505, the sliding block 505 and the outer surface of the rotating rod 501 are both rotatably connected to two pull rods 506 through a rotating shaft, and adjacent pull rods 506 are rotatably connected through a rotating shaft, wherein the outer surfaces of the two pull rods 506 are fixedly connected to a counterweight ball 507, the outer surface of the sliding block 505 is rotatably connected to a slide cylinder 508 through a bearing, the slide cylinder 508 is slidably connected to the positioning column 504, and the slide cylinder 508 An induction transmitter 509 is installed on the outer surface, and the outer surface of the rotating rod 201 is rotatably connected to the connecting block 510. A second cylinder 511 is installed on the inner surface of the frame 1, and the output end of the second cylinder 511 is fixedly connected to the connecting block 510. A plurality of induction receiving switches 512 are installed on the outer surface of the second cylinder 511. The positioning column 504 is fixedly connected to the frame 1, and one of the rotating rods 201 is rotatably connected to the frame 1 through a bearing. A support hole 11 is opened on the inner surface of the frame 1, and multiple rotating rods 201 are slidably connected to the support hole 11. A fixed frame 12 is slidably connected to the frame 1, and a first motor 13 is installed on the surface of the fixed frame 12. The output end of the first motor 13 is fixedly connected to the rotating rod 201, and the fixed frame 12 is rotatably connected to the rotating rod 201 through a bearing. A second motor 14 is fixedly connected to the inner surface of the frame 1, and the output end of the second motor 14 is fixedly connected to the support rod 307.

[0038] The effect is that the first motor 13 outputs power to drive the rotating rod 201 to rotate, and the rotating rod 201 engages with the third bevel gear 502 of the control mechanism 5 through the fourth bevel gear 503, and the rectangular rod drives the rotating rod 501 to rotate. When the operating speed of the equipment increases, the counterweight ball 507 generates a greater centrifugal force as the speed of the rotating rod 501 increases, and pushes the sliding block 505 to slide axially along the rotating rod 501 through the pull rod 506, thereby driving the slide cylinder 508 to move on the positioning column 504. The induction transmitter 509 on the outer surface of the slide 508 approaches the induction receiving switch 512 at different positions as it moves. The induction receiving switch 512 can control the progress of the second cylinder 511, trigger the control system command, and make the piston rod of the second cylinder 511 extend and retract. The position of the rotating rod 201 sliding in the support hole 11 is adjusted by the connecting block 510. The pull rod 506 set on the bracket of the rotating rod 201 and the connecting rod 202 can make the connecting rod 202 move synchronously through the symmetrical arrangement of adjacent pull rods 506 when the rotating rod 201 moves, and always be at the center line position between the two rotating rods 201, and produce up and down displacement. At this time, the distance between adjacent lower rollers 207 can be adjusted according to the rotation speed. The faster the speed of the lower roller 207, the greater the cylinder pulling force corresponding to the induction receiving switch 512 triggered by the induction transmitter 509, and finally the distance between the lower rollers 207 is automatically expanded. When the speed of copper wire transportation increases, the temperature can be reduced by increasing the heat dissipation area of ​​the copper wire.

[0039] Working principle: the first motor 13 installed on the fixed frame 12 outputs power to drive the rotating rod 201 to rotate. The rotating rod 201 is engaged with the third bevel gear 502 of the control mechanism 5 through the fourth bevel gear 503, driving the rotating rod 501 to rotate. When the operating speed of the equipment is increased, the counterweight ball 507 generates a greater centrifugal force as the speed of the rotating rod 501 increases, and pushes the sliding block 505 to slide axially along the rotating rod 501 through the pull rod 506, thereby driving the slide 508 to move on the positioning column 504. The induction transmitter 509 on the outer surface of the slide 508 approaches the induction receiving switch 512 at different positions as the displacement occurs. The induction receiving switch 512 can control the progress of the second cylinder 511, triggering the control system instruction to make the piston of the second cylinder 511 The rod is telescopic, and the rectangular rod slides synchronously inside the rotating rod 501. The position of the rotating rod 201 sliding in the support hole 11 is adjusted by the connecting block 510. The pull rod 506 set on the rotating rod 201 and the connecting rod 202 bracket can make the connecting rod 202 move synchronously through the symmetrical arrangement of adjacent pull rods 506 when the rotating rod 201 moves, and always stays at the center line position between the two rotating rods 201, and produces up and down displacement. At this time, the spacing between adjacent lower rollers 207 can be adjusted according to the speed of rotation. The faster the speed of the lower roller 207, the greater the cylinder tension corresponding to the induction receiving switch 512 triggered by the induction transmitter 509, and finally the spacing between the lower rollers 207 is automatically expanded. When the speed of copper wire transportation increases, the copper wire can be increased by increasing the copper wire. The heat dissipation area is used to cool down the machine. The first gear 204 on the outer surface of the rotating rod 201 and the second gear 205 of the connecting rod 202 form a meshing transmission, so that the two rotate in opposite directions, and then drive the next first gear 204 to rotate, so that all the rotating rods 201 rotate in the same direction, and all the lower rollers 207 rotate synchronously. At this time, the copper wire is sent to the lower roller 207 for transportation. The lower end of the connecting frame 208 slides with the connecting plate 210, and the connecting plate 210 moves horizontally along the slide groove on the lower surface of the support frame 209. The second motor 14 on the top directly drives the support rod 307 to rotate. When the support rod 307 drives the cam 308 to rotate, the wavy curve on the periphery of the cam 308 continuously abuts against the block 306 of the lifting frame 301, converting the rotational motion into a lifting frame. 301 reciprocates along the limit rod 303, and the lifting frame 301 is connected to the lifting rod 203 through a bearing. The shaping wheel 302 at its lower end applies periodic pressure to the copper wire to eliminate residual bending. The spring 309 between the sliding frame 305 and the lifting frame 301 provides a reset force to ensure that the cam 308 can always be in contact with the block 306 on the lifting frame 301. The first cylinder 9 on the mounting frame 8 can drive the sliding plate 10 to move axially along the support rod 307. Through the cooperation of the limit block 6 and the limit slide groove 7, the axial position of the cam 308 on the support rod 307 is adjusted, and the effective radius of the action curve of the cam 308 is changed, thereby adapting to the different shaping requirements of hard and soft copper wires, avoiding the hard material from breaking due to excessive pressure or the soft material from deforming due to excessive shaping.The connecting rod 202 drives the connecting plate 210 to move through the connecting frame 208, and the connecting plate 210 always slides along the bottom of the support frame 209 and remains vertical. When the spacing of the lower rollers 207 is adjusted, the connecting rod 202 will move in the vertical direction. At this time, the connecting frame 208 can slide with the connecting plate 210, and the provided lifting rod 203 always slides inside the vertical slot 211, so that it can be adjusted synchronously with the position of the connecting rod 202, so that the top plastic wheel also remains at the center line position of the two adjacent lower rollers 207, so that it is misaligned up and down. When the support rod 307 rotates, the first bevel gear 403 at its outer end engages with the second bevel gear 404 at the upper end of the mounting rod 402, driving the mounting rod 402 to rotate, and the second bevel gear 404 at the lower end of the mounting rod 402 drives the first bevel gear 403 at the outer end of the blowing pipe 401 Gear 403 causes the blowpipe 401 to rotate at a constant speed around its axis. The air holes evenly distributed on the outer wall of the blowpipe 401 form a spiral airflow during rotation. Compared to a fixed blowpipe, this can more evenly cover the copper wire surface, remove the heat generated by plastic deformation and friction during the straightening process, and effectively control the copper wire temperature below the critical annealing temperature. During actual operation, the copper wire enters the equipment from the inlet and first passes through the lower roller 207 set of the spacing adjustment mechanism 2. Based on real-time adjustments by the control mechanism 5, the roller spacing automatically matches the copper wire specifications and operating speed. Driven by the cam 308, the shaping wheel 302 refines the copper wire surface, eliminating wavy bends and spiral bends. Throughout this process, the rotating blowpipe 401 of the cooling mechanism 4 continuously sprays cooling air to prevent the copper wire from softening due to temperature rise. Ultimately, the copper wire achieves the straightness required for precision machining before being output from the outlet.
