Description

Technical Field

[0001] The present invention relates to the technical field of stranding machines, and particularly to a high-speed copper wire stranding machine with balanced tension. Background Art

[0002] In industrial fields such as wire and cable manufacturing and electrical connection, a stranding machine is a key device for achieving the stranding of multiple copper wires into a strand. Its performance directly affects the quality and stability of the finished product. To ensure that the stranded copper wires are tightly combined and avoid loosening or breaking, a tension adjustment mechanism is set on the path of each copper wire, which has become a necessary technical means to guarantee the stranding quality.

[0003] In the prior art, when the diameter of the copper wire spool gradually decreases due to continuous wire release, the industry generally adopts the method of installing a pressure sensor at the tension adjustment wheel to monitor the tension of each copper wire in real time and achieve automatic adjustment. This solution senses the copper wire tension based on electronic components and can effectively maintain the uniform force of each copper wire during the stranding process with high precision.

[0004] However, practical applications have shown that this tension adjustment solution relying on electronic components has significant defects. In the copper wire stranding production environment, complex factors such as mechanical vibration, dust, and humidity exist for a long time. Electronic components such as pressure sensors are extremely easy to be damaged due to external force impact, circuit failure, or environmental erosion. Frequent failures have led to a significant increase in the frequency of equipment maintenance and repair, not only significantly increasing the operating cost, but also requiring staff to continuously invest energy in equipment inspection, repair, and replacement of parts, greatly increasing the labor burden and severely restricting the improvement of production efficiency, making it difficult to meet the requirements of high-efficiency and stable production in modern industry. Summary of the Invention

[0005] Based on this, the purpose of the present invention is to provide a high-speed copper wire stranding machine with balanced tension to solve the technical problems in the above background art.

[0006] To achieve the above purpose, the present invention provides the following technical solution: A high-speed copper wire stranding machine with balanced tension, including a stranding disc and a copper wire wheel. A plurality of sets of clamping mechanisms for clamping and supporting the copper wire wheel are evenly arranged outside the stranding disc;

[0007] The clamping mechanism includes a flipping clamping plate rotatably connected to the stranding disc through a flipping hinge seat. Both ends of the flipping clamping plate are rotatably connected with rotating clamping arms that cooperate with the placement shaft. The clamping hole formed after the two rotating clamping arms are closed plays a role in actively supporting the placement shaft, and a locking member is used to lock the two rotating clamping arms after they are closed;

[0008] A plurality of tension balance mechanisms corresponding to the engaging mechanism are connected to the inner side of the wire stranding reel. The tension balance mechanism includes an elastic sliding plate elastically connected through a spring frame inside the wire stranding reel. One end of the elastic sliding plate is fixed with an adjusting frame, and the top of the adjusting frame is movably connected with a pressing roller shaft that abuts against the outer surface of the copper wire of the copper wire wheel. The pressing roller shaft functions to abut and press the outer surface of the copper wire of the copper wire wheel under the elastic contraction force of the spring frame.

[0009] One end of each elastic sliding plate is fixed with a connecting plate that penetrates the wire stranding reel. One end of the connecting plate is movably connected with a tensioning arm, and the tensioning wheel movably connected to the end of the tensioning arm functions to provide a tensioning force for the single-strand copper wire. One end of the wire stranding reel is obliquely fixed with a fixed arm that extends into the tensioning arm and is movably connected to the tensioning arm through a movable rod.

[0010] The tension balance mechanism further includes a wire threading groove, and the wire threading groove is opened between the two pressing roller shafts and in the middle of the adjusting frame. The wire threading groove functions to guide and limit the single-strand copper wire during the wire threading and wire releasing processes.

[0011] The tension balance mechanism further includes a guide rod. The guide rod is fixed inside the wire stranding reel and penetrates the elastic sliding plate. The guide rod functions to stably slide the elastic sliding plate. The top of the spring frame is fixed to the inner side of the wire stranding reel, and its bottom is fixed to the elastic sliding plate, functioning to elastically slide the elastic sliding plate.

[0012] The tension balance mechanism further includes a first limiting wheel movably connected above the fixed arm and a second limiting wheel movably connected to the inner side of the wire stranding reel. The single-strand copper wire sequentially passes through the wire threading groove, the second limiting wheel, the first limiting wheel and fits with the tensioning wheel.

[0013] Drive shafts and drive rods are respectively fixed at the central positions of both ends of the wire stranding reel. A dividing reel is fixed at the end of the drive rod. A bracket matching the dividing reel is fixed on the top of the base, and a bundling reel on the same axis as the dividing reel is fixed on the top of the bracket.

[0014] The outer side of the drive shaft is movably supported and connected to a support cylinder fixed to the base. A motor is installed on the base, and drive wheels connected by a transmission belt are fixed to the output end of the motor and one end of the drive shaft.

[0015] By adopting the above technical solutions, in terms of stability, the method of relying on vulnerable electronic components to monitor the tension of the copper wire is abandoned, and the adaptive tension balance adjustment is realized through a mechanical structure, avoiding the damage of electronic components caused by complex environmental factors such as mechanical vibration, dust, and humidity, reducing the frequency of equipment maintenance and repair, lowering the operation cost, lightening the labor burden of the staff, ensuring the long-term stable operation of the equipment. Its tension balance mechanism can automatically adjust the tension force according to the wire releasing degree of the copper wire wheel. During the wire releasing process of the copper wire wheel, it ensures that the extrusion roller shaft always fits the copper wire. By the coordinated action of the spring frame and the tension wheel, the tension degree of the copper wire remains consistent during different unwinding processes, effectively avoiding the loosening or breaking of the copper wire, improving the stranding quality. Moreover, this equipment has a wide range of applications. By replacing the spring frames with different elastic forces, it can adapt to the stranding requirements of copper wires with different diameters and purities, enhancing the versatility and flexibility of the equipment, meeting the diverse production requirements, improving the production efficiency, and promoting the efficient development of industrial fields such as wire and cable manufacturing and electrical connection.

[0016] Furthermore, the tension balance mechanism further includes a hinge frame and a mounting frame. The connecting plate and the tension arm are rotatably connected through the hinge frame, and the second limiting wheel is rotatably connected to the stranding disc through the mounting frame.

[0017] By adopting the above technical solutions, the hinge frame plays a role in rotatably connecting the tension arm, and the mounting frame plays a role in movably supporting the second limiting wheel.

[0018] Furthermore, a base for movably supporting the stranding disc is arranged at the bottom of the stranding disc, and support mechanisms matched with the stranding disc are fixed on both sides inside the base. The support mechanism consists of an arc-shaped support frame and multiple groups of support rollers. The multiple groups of support rollers play a role in movably supporting the stranding disc during rotation, and support arms for enhancing firmness are also fixed on both sides of the arc-shaped support frame.

[0019] By adopting the above technical solutions, the multiple groups of support rollers are made of wear-resistant rubber material, installed on the arc-shaped support frame, and connected to the frame through bearings, and can rotate flexibly, providing stable movable support for the rotation of the stranding disc. The support arms are welded on both sides of the arc-shaped support frame, enhancing the firmness of the support frame.

[0020] In summary, the present invention mainly has the following beneficial effects: In terms of stability, the present invention abandons the method of relying on vulnerable electronic components to monitor the tension of the copper wire, and realizes the self-adaptive tension balance adjustment through a mechanical structure, avoiding the damage of electronic components caused by complex environmental factors such as mechanical vibration, dust, and humidity, reducing the frequency of equipment maintenance and repair, lowering the operation cost, reducing the labor burden of the staff, ensuring the long-term stable operation of the equipment. Its tension balance mechanism can automatically adjust the tension according to the wire release degree of the copper wire wheel. During the wire release process of the copper wire wheel, it ensures that the extrusion roller shaft always fits the copper wire. With the coordinated action of the spring frame and the tension wheel, the tension of the copper wire remains consistent during different unwinding processes, effectively avoiding the loosening or breaking of the copper wire and improving the stranding quality. Moreover, this equipment has a wide range of applications. By replacing the spring frames with different elastic forces, it can adapt to the stranding requirements of copper wires with different diameters and purities, enhancing the versatility and flexibility of the equipment, meeting diverse production requirements, improving production efficiency, and promoting the efficient development of industrial fields such as wire and cable manufacturing and electrical connection.

The embodiments described below by referring to the accompanying drawings are exemplary and are only used to explain the present invention and should not be construed as a limitation to the present invention.

[0036] Next, the embodiments of the present invention will be described according to the overall structure of the present invention.

[0037] Embodiment 1

[0038] As Figure 1-13 shown, this embodiment focuses on a high-speed copper wire stranding machine with balanced tension. Its structural design focuses on stable wire feeding, precise tension adjustment, and efficient stranding, and is mainly composed of components such as a wire stranding disc 1, a copper wire wheel 3, an engaging mechanism 2, a tension balancing mechanism 4, and a base 6;

[0039] The stranding reel 1 is made of high-strength aluminum alloy and manufactured by precision casting process, with good strength and dynamic balance performance. A base 6 is provided at the bottom of the stranding reel 1. The base 6 is welded by high-quality carbon steel and has a stable structure. Fixed support mechanisms 5 are provided on both sides inside the base 6. The arc-shaped support frame 501 is made of Q345B steel and is connected to the base 6 by welding. Its arc is adapted to the stranding reel 1. Multiple groups of support rollers 502 are made of wear-resistant rubber material and are installed on the arc-shaped support frame 501 and connected to the frame through bearings, which can rotate flexibly and provide stable movable support for the rotation of the stranding reel 1. The support arms 503 are welded on both sides of the arc-shaped support frame 501, enhancing the firmness of the support frame;

[0040] Drive shafts 7 and drive rods 8 are respectively fixed at the central positions of both ends of the stranding reel 1. The drive shafts 7 and drive rods 8 are both made of 40Cr alloy steel and are quenched and tempered to improve strength and toughness. A support cylinder 9 is movably supported and connected to the outside of the drive shaft 7. The support cylinder 9 is made of seamless steel pipe and is welded to the base 6 through the rod body. A motor 10 is installed on the base 6. The motor 10 is a YE3 series high-efficiency energy-saving motor, and its power is determined according to the specifications and production requirements of the stranding machine. For example, for a general specification of the stranding machine, a 5.5kW motor can be selected. Drive wheels 11 are respectively fixed at the output end of the motor 10 and one end of the drive shaft 7. The drive wheels 11 are made of gray cast iron and are connected by a transmission belt 12 to realize the drive of the motor to the stranding reel 1;

[0041] The engaging mechanisms 2 are evenly arranged on the outside of the stranding reel 1. Each group of engaging mechanisms 2 includes a flipping engaging plate 201. The flipping engaging plate 201 is rotatably connected to the stranding reel 1 through a flipping hinge seat 206. The flipping hinge seat 206 is made of stainless steel to ensure flexible rotation and corrosion resistance. The two ends of the flipping engaging plate 201 are rotatably connected to rotating engaging arms 202. After the two groups of rotating engaging arms 202 are closed to each other, an engaging hole 203 is formed for movably supporting the placing shaft 204. The placing shaft 204 is made of 45 steel and its surface is quenched to improve hardness and wear resistance. The locking piece 205 is a high-strength bolt and nut for locking the two groups of rotating engaging arms 202 to ensure the stable installation of the placing shaft 204 and the copper wire wheel 3;

[0042] The tension balance mechanism 4 is connected to the inside of the stranding reel 1 and corresponds to the engaging mechanisms 2 one by one. The elastic sliding plate 401 is made of aluminum alloy and is elastically connected inside the stranding reel 1 through a spring frame 412. The spring frame 412 is made of spring steel and is heat-treated to ensure good elasticity and stability. One end of the elastic sliding plate 401 is fixed with an adjusting frame 402. The adjusting frame 402 is made of aluminum alloy and is connected to the elastic sliding plate 401 by welding. The top of the adjusting frame 402 is movably connected with an extrusion roller shaft 403. The extrusion roller shaft 403 is a metal roller coated with polyurethane rubber, which can not only ensure the extrusion effect on the copper wire but also avoid damaging the copper wire;

[0043] The wire threading groove 404 is opened between two sets of extrusion roller shafts 403 and in the middle of the adjusting frame 402. It is made of stainless steel with a smooth surface, playing a role of guiding and limiting the wire threading and wire releasing processes of single-strand copper wires. The guiding rod 413 is fixed inside the stranding disc 1, made of stainless steel, passing through the elastic sliding plate 401 to ensure the stable sliding of the elastic sliding plate 401. The connecting plate 405 is fixed at one end of the elastic sliding plate 401, made of aluminum alloy, passing through the stranding disc 1. One end of the connecting plate 405 is rotatably connected to the tensioning arm 406 through the hinge frame 407. The hinge frame 407 is made of stainless steel. The end of the tensioning arm 406 is movably connected to the tensioning wheel 408. The tensioning wheel 408 is made of rubber, providing tension for the single-strand copper wire;

[0044] The fixed arm 409 is obliquely fixed at one end of the stranding disc 1, extending into the tensioning arm 406, and is movably connected to the tensioning arm 406 through the movable rod 411. The first limiting wheel 410 is movably connected above the fixed arm 409. The second limiting wheel 415 is rotatably connected to the stranding disc 1 through the mounting frame 414. The limiting wheels are all made of rubber, playing a role of guiding and limiting the copper wire;

[0045] The end of the transmission rod 8 is fixed with the wire distributing disc 13. The wire distributing disc 13 is made of aluminum alloy and is connected to the transmission rod 8 by welding. The top of the base 6 is fixed with the support 15. The support 15 is welded by angle steel, and the wire bundling disc 14 is fixed at the top. The wire bundling disc 14 is made of aluminum alloy and is on the same axis as the wire distributing disc 13, ensuring that the copper wire can smoothly pass through the wire distributing disc 13 and the wire bundling disc 14 during the stranding process to achieve stranding and output;

[0046] Equipment Installation and Preparation

[0047] Select a suitable installation location in the production workshop, place the base 6 on a flat ground to ensure the stability of the base. Install the support mechanism 5 on both sides inside the base 6, check whether the support rotating wheel 502 rotates flexibly. Install the motor 10, the support cylinder 9, the transmission shaft 7, the transmission rod 8, the transmission wheel 11 and the transmission belt 12, adjust the tension of the transmission belt to ensure that the motor can stably drive the stranding disc 1 to rotate. Install the clamping mechanism 2 on the outside of the stranding disc 1, check whether the functions of the flipping clamping plate 201, the rotating clamping arm 202 and the locking part 205 are normal. Install the tension balance mechanism 4 inside the stranding disc 1, check whether components such as the elastic sliding plate 401, the spring frame 412 and the extrusion roller shaft 403 are firmly installed, and whether each movable part can move flexibly. Install the wire distributing disc 13, the wire bundling disc 14 and the support 15 to ensure that the axes of the wire distributing disc 13 and the wire bundling disc 14 are consistent;

[0048] Installation of the copper wire reel 3

[0049] Power on the device. The staff members sequentially open multiple sets of clamping mechanisms 2. First, remove the locking member 205, manually open the two sets of rotating clamping arms 202 to both sides, then rotate the flipping clamping plate 201 along the flipping hinge seat 206 to open it. Insert the copper wire wheel 3 wound with single-strand copper wire outside the placement shaft 204. After installation, reset the clamping mechanism 2 to close the two sets of rotating clamping arms 202. The clamping hole 203 provides movable support for one end of the placement shaft 204. The inner side of the rotating clamping arm 202 abuts against the end face of the copper wire wheel 3 to prevent the axial movement of the copper wire wheel 3 when releasing the copper wire. According to production requirements, install an appropriate amount of copper wire wheels 3 on the device. For example, install four sets of copper wire wheels 3 for the stranding operation of four strands of copper wire;

[0050] Threading and Debugging

[0051] In the early stage of stranding, pull out single-strand copper wires from each copper wire wheel 3, sequentially pass them through the wire groove 404, outside the second limiting wheel 415, outside the first limiting wheel 410, and outside the tensioning wheel 408. Then pass each single-strand copper wire through the corresponding holes on the wire distributing plate 13 and finally gather and pass out through the central hole of the wire bundling plate 14 to be connected to the external winding mechanism. Check whether the threading path of the copper wire is correct and whether each limiting wheel and tensioning wheel can properly guide and tension the copper wire. According to the diameter and purity of the single-strand copper wire, select a spring frame 412 with appropriate elasticity for installation to ensure that the elasticity of the spring frame 412 matches the tension required for copper wire stranding;

[0052] Stranding Operation

[0053] Start the motor 10. The motor drives the transmission shaft 7 to rotate at high speed through the transmission belt 12, so that the stranding disc 1 drives the entire copper wire wheel 3 to revolve through multiple sets of clamping mechanisms 2. At the same time, the external winding mechanism actively rotates to wind the stranded copper wire. The winding tension causes each copper wire wheel 3 to passively rotate to release the wire. As the copper wire wheel 3 releases the wire, the diameter of the copper wire wound on its outer side gradually decreases. Under the action of the spring frame 412, the extrusion roller shaft 403 always fits the surface of the copper wire and moves radially. It drives the elastic sliding plate 401 to slide radially inside the stranding disc 1 through the adjusting frame 402;

[0054] One end of the elastic sliding plate 401 drives one end of the tensioning arm 406 to move radially outwards through the connecting plate 405. Since the middle position of the tensioning arm 406 is movably connected to the movable rod 411, the other end of the tensioning arm 406 drives the tensioning wheel 408 to move towards the center of the stranding disc 1 to compress and tension the limited copper wire. During the stranding process, observe the stranding quality of the copper wire, check whether the stranded copper wire is tight, uniform, and whether there are any loose or broken phenomena. If problems are found, stop the machine in time for inspection and adjustment. For example, check the operation of each component and whether the elasticity of the spring frame 412 is appropriate, etc.

[0055] Equipment Maintenance and Cleaning

[0056] After the stranding work is completed, turn off the motor 10 and the winding mechanism, and clean the copper chips and dust on the surface and inside of the equipment, especially on the surface of the tension balance mechanism 4, the engaging mechanism 2, and each limit wheel and tension wheel, to prevent copper chips and dust from affecting the normal operation of the equipment. Regularly check the wear conditions of each component, such as the support runner 502, the extrusion roller shaft 403, the tension wheel 408, etc., and replace the severely worn components in a timely manner. Check whether the connection parts are loose, such as bolts, hinge joints, etc., and tighten them in a timely manner. Regularly check the elasticity of the spring bracket 412. If the elasticity decreases, replace the spring bracket 412 in a timely manner to ensure the normal operation of the tension balance mechanism 4.

[0057] The working principle of the present invention is as follows: When in use, power on, and the staff sequentially opens multiple groups of engaging mechanisms 2, and inserts the copper wire wheel 3 wound with single-strand copper wire outside the placing shaft 204, wherein the placing shaft 204 and the stranding disc 1 are rotationally connected through bearings;

[0058] Specifically, first remove the locking part 205, then manually open the two groups of rotating engaging arms 202 to both sides, and then rotate the flipping engaging plate 201 along the flipping hinge seat 206 as a whole to open, so that the copper wire wheel 3 can be inserted outside the placing shaft 204. After the installation is completed, at this time, perform a reset operation on the engaging mechanism 2 to close the two groups of rotating engaging arms 202, so that the engaging hole 203 formed between them plays a role in actively supporting one end of the placing shaft 204. At the same time, the inner side surface of the rotating engaging arm 202 will abut against the end surface of the copper wire wheel 3, thereby avoiding the problem of axial movement of the copper wire wheel 3 when the copper wire is released passively and ensuring the stability of the copper wire unwinding;

[0059] According to the actual production situation, one to eight groups of copper wire wheels 3 can be installed on this equipment, that is to say, the minimum double-strand copper wire stranding or the maximum eight-group copper wire stranding operation can be carried out;

[0060] Furthermore, after the copper wire wheel 3 is installed inside the engaging mechanism 2, at this time, the adjusting frame 402 and the extrusion roller shaft 403 in the tension balance mechanism 4 corresponding to each group of engaging mechanisms 2, under the action of the spring bracket 412, make the outer wall of the extrusion roller shaft 403 contact the copper wire wound on the outermost layer of the copper wire wheel 3. At this time, the spring bracket 412 is in a stretched state. That is to say, as the copper wire wheel 3 gradually pays out the wire, the diameter of the copper wire wound on the outside of the copper wire wheel 3 gradually decreases. At this time, under the action of the spring bracket 412, it can be ensured that the extrusion roller shaft 403 always contacts the outer surface of the copper wire;

[0061] In the early stage of stranding, each single-strand copper wire in each group is pulled out from the copper wire reel 3, passes through the wire threading groove 404, and then the copper wire sequentially passes outside the second limiting wheel 415, outside the first limiting wheel 410, and outside the tensioning wheel 408. Then, each single-strand copper wire in each group passes through the corresponding hole on the wire dividing plate 13, and finally converges and passes out through the central hole of the wire bundling plate 14 to be connected to the external winding mechanism;

[0062] During the stranding process, the external winding mechanism rotates actively to wind the stranded copper wire. During the winding process, a certain pulling force will be generated on each single-strand copper wire in each group. At this time, each copper wire reel 3 rotates passively and rotates on the outside of the placing shaft 204 to perform wire releasing operations. At the same time, under the action of the high-speed rotation of the transmission shaft 7, the stranding disk 1 drives the copper wire reel 3 to perform an overall revolution operation through multiple sets of engaging mechanisms 2. At the same time, under the action of the transmission rod 8, the wire dividing plate 13 rotates synchronously at this time, and multiple groups of copper wires can be stranded into a thicker copper wire according to a certain rule;

[0063] Furthermore, as the copper wire is stranded, the diameter of the copper wire wound outside each copper wire reel 3 gradually decreases. Due to the action of the spring frame 412, the extrusion roller shaft 403 always fits the surface of the copper wire and moves radially at this time. Then, the elastic sliding plate 401 is driven by the adjusting frame 402 to slide radially inside the stranding disk 1. At this time, one end of the elastic sliding plate 401 drives one end of the tensioning arm 406 to move radially outward through the connecting plate 405. Since the middle position of the tensioning arm 406 is movably connected to the movable rod 411, the other end of the tensioning arm 406 drives the tensioning wheel 408 to move towards the center of the stranding disk 1 at this time, and the copper wire it limits can be compressed and tensioned;

[0064] At the same time, due to the high-speed rotation of the stranding disk 1, the elastic sliding plate 401 will always maintain an outward expansion trend inside the stranding disk 1 due to the action of centrifugal force. That is to say, the extrusion roller shaft 403 performs a better and more stable extrusion operation on the outer surface of the copper wire. Similarly, the extrusion roller shaft 403 and the adjusting frame 402 are movably connected. That is to say, the extrusion roller shaft 403 will rotate passively relative to the adjusting frame 402 during the wire releasing process, thus avoiding the problem that the surface of the extrusion roller shaft 403 causes friction to the single-strand copper wire, resulting in damage or even fracture;

[0065] As can be seen from the above, the tension balance mechanism 4 adopted by this device does not use electronic components to monitor the tension degree of the copper wire, thus avoiding the problems that in the copper wire stranding production environment, complex factors such as mechanical vibration, dust, and humidity exist for a long time, resulting in the electronic components such as pressure sensors being extremely easy to be damaged due to external force impact, circuit failure, or environmental erosion, and the frequent failures causing a significant increase in the frequency of equipment maintenance and repair. The overall use stability is better. At the same time, an adaptive tension balance mode is adopted, and the tensioning effect on the remaining copper wire during the wire release process is automatically adjusted according to the wire release degree of the copper wire wheel 3, with better use effect, and the operation and maintenance are more convenient;

[0066] Furthermore, after the single-strand copper wire threading is completed, at this time, the tension degree of the copper wire by the tensioning arm 406 meets the tension degree standard for copper wire stranding. As the stranding operation progresses, the tension degree of the copper wire by the tension balance mechanism 4 gradually increases, always ensuring that the tension degree of the copper wire is consistent during any wire unwinding process, and the use effect is better;

[0067] Similarly, according to the different diameters and purities of the single-strand copper wire, the applicable tension degree of the copper wire during the stranding process is also different. At this time, the staff can replace and adjust the spring frame 412 to make the elastic force of the spring frame 412 in a corresponding relationship with the tension degree of the copper wire, and then can adapt to the adaptive tension balance adjustment operation during the stranding process of copper wires of different specifications, and the application range is relatively wide.
