Description

Technical Field

[0001] The present invention relates to the technical field of copper wire straightening, and particularly to a copper wire straightening device for cable processing. Background Art

[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 devices generally have problems such as poor parameter adaptability, insufficient temperature control, and low straightening accuracy: on the one hand, most devices adopt a design with fixed roller spacing and pressure. When facing copper wires with different diameters and hardnesses, it is necessary to manually replace the rollers or adjust the parameters, which not only takes time and effort, but also easily causes copper wire breakage or surface scratches due to improper parameter matching; on the other hand, during high-speed straightening, the heat generated by plastic deformation and friction is difficult to effectively dissipate, often causing annealing and softening of the copper wire, reducing the material strength and electrical conductivity; in addition, the shaping mechanisms of traditional devices are mostly static structures and cannot dynamically adjust the straightening force according to the real-time state of the copper wire, resulting in poor straightening effects for complexly bent or profiled copper wires.

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

[0015] 1. The present invention provides a copper wire straightening device for cable processing. The first motor drives the rotating rod, and through bevel gear transmission, the rotating rod operates. When the speed increases, the centrifugal force of the counterweight ball drives the induction component to trigger the control system, accurately adjusting the position of the rotating rod, and then changing the distance between the lower rollers. This design breakthroughly realizes the adaptive matching of the copper wire transportation speed and the straightening parameters. Compared with traditional devices with fixed distances, it can avoid the breakage of copper wires due to excessive reverse bending amplitude during high-speed operation. At the same time, by increasing the distance between the rollers, the heat dissipation area is increased, preventing the copper wires from overheating and annealing due to increased speed. No matter what specifications of copper wires are processed, the device can always maintain stable and efficient straightening performance, significantly improving production efficiency, reducing the rejection rate, and reducing material waste and downtime for debugging caused by mismatched equipment parameters.

[0016] 2. The present invention provides a copper wire straightening device for cable processing. Through the precise design of the shaping mechanism, high-precision straightening of copper wires of multiple materials is achieved. The second motor drives the cam to rotate, and its wavy curve cooperates with the spring reset structure to apply periodic pressure on the copper wire by the shaping wheel, 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 hardnesses. This dynamic shaping scheme can intelligently adapt to the hardness differences of copper wires compared with the traditional fixed-pressure straightening. For hard copper wires, it can avoid breakage caused by excessive pressure; for soft copper wires, it can prevent surface damage caused by over-shaping. Without the need for manual frequent replacement of equipment parameters, it can automatically match the optimal straightening force, greatly improving the versatility of the equipment, meeting the production requirements of diverse products in the cable processing industry, effectively reducing the cost of manual intervention, and improving the production automation level and product quality stability.

[0017] 3. The present invention provides a copper wire straightening device for cable processing. Through the precise cooperative structure of the spacing adjustment and shaping mechanisms, high precision and stability of the straightening process are ensured. The connecting rod drives the connecting plate to slide, and in cooperation with the synchronous movement of the lifting rod in the vertical groove, the shaping wheel is always accurately positioned at the center line position of two adjacent lower rollers. Compared with the traditional separate adjustment structure, this design can avoid the position deviation of the shaping wheel caused by adjusting the spacing of the lower rollers. No matter how the spacing of the lower rollers changes, the shaping wheel can maintain a uniform distribution of pressure on the copper wire, eliminating problems of local over-straightening or insufficient straightening. It is especially suitable for the production of precision cables with strict surface quality requirements, can effectively improve product consistency, reduce rework and scrapping caused by straightening deviation, and ensure high-quality output of cable products.

[0018] 4. The present invention provides a copper wire straightening device for cable processing. Its rotary cooling mechanism provides efficient heat dissipation protection for the copper wire. The support rod drives the air blowing pipe to rotate through bevel gear transmission, generating a spiral air flow that evenly covers the surface of the copper wire. Compared with the traditional fixed blowing cooling, this design significantly enhances the uniformity and effectiveness of heat dissipation, can quickly remove 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 material properties of the copper wire. It is especially suitable for the processing of special cables sensitive to temperature, such as tinned copper wires, enameled wires, etc., can avoid the decline in electrical conductivity or coating damage caused by annealing effects, effectively improve product quality, extend the continuous operation time of the equipment, and enhance the competitiveness of enterprises in the high-end cable market.

Detailed implementation manners

[0029] In order to more clearly understand the above-mentioned objects, features and advantages of the present invention, the present invention will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, without conflict, the embodiments of the present application and the features in the embodiments can be combined with each other.

[0030] In the following description, many specific details are set forth in order to fully understand the present invention. However, the present invention may be implemented in other ways different from those described herein. Therefore, the present invention is not limited by the specific embodiments disclosed in the following specification.

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

[0032] The effect is that 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 drive, causing the two to rotate in opposite directions, and then driving 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. The lower end of the connecting frame 208 is slidably matched with the connecting plate 210, and the connecting plate 210 moves horizontally along the chute on the lower surface of the support frame 209. Among them, the connecting rod 202 drives the connecting plate 210 to move through the connecting frame 208. The connecting plate 210 always slides along the bottom of the support frame 209 and remains vertical. When adjusting the spacing between the lower rollers 207, the connecting rod 202 will have a vertical displacement. At this time, the connecting frame 208 can slide with the connecting plate 210. The provided lifting rod 203 always slides inside the vertical groove 211, so that it can be adjusted synchronously with the position of the connecting rod 202.

[0033] As Figures 1-9As shown in the figure, a shaping mechanism 3 is further provided inside the frame 1. The shaping mechanism 3 includes a lifting frame 301. The lifting frame 301 is rotatably connected to the lifting rod 203 through a bearing. A shaping wheel 302 is rotatably connected to the outer surface of the lifting rod 203. A limiting rod 303 is fixedly connected to the upper surface of the lifting frame 301. A limiting groove 304 is formed on the outer surface of the support frame 209. A sliding frame 305 is slidably connected to the inner surface of the limiting groove 304. The sliding frame 305 is slidably connected to the limiting rod 303. A blocking block 306 is fixedly connected to the upper surface of the lifting frame 301. A support rod 307 is rotatably connected to the inner surface of the frame 1 through a bearing. A cam 308 is slidably connected to the outer surface of the support rod 307. The blocking block 306 abuts against the cam 308. A spring 309 is fixedly connected between the sliding frame 305 and the lifting frame 301. A limiting block 6 is fixedly connected to the inner surface of the cam 308. A limiting chute 7 is formed on the outer surface of the support rod 307. The limiting block 6 is slidably connected to the limiting chute 7. An installation frame 8 is fixedly connected to the lower surface of the sliding frame 305. A first air cylinder 9 is installed on the outer surface of the installation frame 8. The output end of the first air cylinder 9 is fixedly connected to a sliding plate 10. The sliding plate 10 is rotatably connected to the cam 308 through a bearing. The installation 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 blocking block 306 of the lifting frame 301, converting the rotational motion into the reciprocating motion of the lifting frame 301 along the limiting 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 restoring force to ensure that the cam 308 can always contact the blocking block 306 on the lifting frame 301. The first air cylinder 9 on the installation frame 8 can drive the sliding plate 10 to move axially along the support rod 307. By the cooperation of the limiting block 6 and the limiting chute 7, the axial position of the cam 308 on the support rod 307 is adjusted, changing the effective radius of the acting curve of the cam 308, so as to adapt to the different shaping requirements of hard and soft copper wires, and avoid the hard material from breaking due to excessive pressure or the soft material from deforming due to excessive shaping.

[0035] As Figures 1-9 As shown in the figure, a cooling mechanism 4 is further provided inside the frame 1. The cooling mechanism 4 includes a blowing air pipe 401 and an installation rod 402. First bevel gears 403 are fixedly connected to the outer surfaces of the blowing air pipe 401 and the support rod 307 respectively. Second bevel gears 404 are fixedly connected to the upper and lower surfaces of the installation rod 402 respectively. The two first bevel gears 403 are respectively meshed with the adjacent second bevel gears 404. Positioning frames 405 are fixedly connected to the surfaces of the support frame 209 and the frame 1. The blowing air pipe 401, the installation rod 402 and the support rod 307 are respectively rotatably connected to the positioning frames 405 through bearings. The blowing air 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 rotation of the rotating rod 201. The rotating rod 201 meshes with the third bevel gear 502 of the control mechanism 5 through the fourth bevel gear 503, and the rectangular rod drives the rotation of the rotating rod 501. When the operating speed of the equipment increases, the counterweight ball 507 generates a greater centrifugal force as the rotation speed of the rotating rod 501 increases. The sliding block 505 is pushed along the axial direction of the rotating rod 501 through the pull rod 506, thereby driving the sliding cylinder 508 to move on the positioning column 504. The induction transmitter 509 on the outer surface of the sliding cylinder 508 approaches the induction receiving switches 512 at different positions with the displacement. The induction receiving switches 512 can control the process of the second cylinder 511, trigger the control system command, so that the piston rod of the second cylinder 511 expands and contracts, and the rotating rod 201 is adjusted through the connecting block 510 at the position where it slides in the support hole 11. The pull rod 506 arranged between the rotating rod 201 and the connecting rod 202 bracket can, when the rotating rod 201 moves, through the symmetrical arrangement of the adjacent pull rods 506, make the connecting rod 202 move synchronously and always be at the center line position between the two rotating rods 201 and generate an up and down displacement. At this time, the distance between the adjacent lower rollers 207 can be adjusted according to the rotation speed. The faster the speed of the lower rollers 207, the greater the pulling force of the cylinder corresponding to the induction receiving switch 512 triggered by the induction transmitter 509, and finally the distance between the lower rollers 207 is automatically enlarged. When the transportation speed of the copper wire 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 fixing frame 12 outputs power to drive the rotating rod 201 to rotate. The rotating rod 201 meshes 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 device increases, the counterweight ball 507 generates a greater centrifugal force as the rotational speed of the rotating rod 501 increases. It pushes the slider 505 to slide along the axial direction of the rotating rod 501 through the pull rod 506, thereby driving the sliding cylinder 508 to move on the positioning column 504. The induction transmitter 509 on the outer surface of the sliding cylinder 508 approaches the induction receiving switches 512 at different positions with the displacement. The induction receiving switches 512 can control the process of the second cylinder 511, trigger the control system command, cause the piston rod of the second cylinder 511 to extend and retract, and the rectangular rod slides synchronously inside the rotating rod 501. The rotating rod 201 is adjusted through the connecting block 510 at the position where it slides in the support hole 11. The pull rod 506 provided between the rotating rod 201 and the connecting rod 202 bracket can, when the rotating rod 201 moves, through the symmetric arrangement of adjacent pull rods 506, cause the connecting rod 202 to move synchronously and always be at the center line position between the two rotating rods 201 and generate vertical displacement. At this time, the distance between adjacent lower rollers 207 can be adjusted according to the rotational speed. The faster the speed of the lower rollers 207, the greater the pulling force of the cylinder corresponding to the induction receiving switch 512 triggered by the induction transmitter 509, and finally the distance between the lower rollers 207 is automatically enlarged. When the transportation speed of the copper wire increases, the temperature can be reduced by increasing the heat dissipation area of the copper wire. The first gear 204 on the outer surface of the rotating rod 201 forms a meshing drive with the second gear 205 of the connecting rod 202, causing the two to rotate in opposite directions and driving 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 fed onto the lower rollers 207 for transportation. The lower end of the connecting frame 208 is slidably matched with the connecting plate 210, and the connecting plate 210 moves horizontally along the chute on the lower surface of the support frame 209. The second motor 14 at 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 outer circumference of the cam 308 continuously abuts against the abutting block 306 of the lifting frame 301, converting the rotational motion into the reciprocating motion of the lifting frame 301 along the limiting 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 a 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 restoring force to ensure that the cam 308 can always contact the abutting block 306 on the lifting frame 301. The first cylinder 9 on the mounting frame 8 can drive the sliding plate 10 to move along the axial direction of the support rod 307. By the cooperation of the limiting block 6 and the limiting chute 7, the axial position of the cam 308 on the support rod 307 is adjusted, changing the effective radius of the acting curve of the cam 308, so as to adapt to the different shaping requirements of hard and soft copper wires, and avoid 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.
