Description

Technical Field

[0001] The present invention belongs to the technical field of wire drawing equipment, and relates to a thick copper wire drawing device for vehicle-grade high-power devices. Background Technique

[0002] Copper wires have good electrical conductivity, which leads to their frequent use in manufacturing wires and cables. Among them, in order to make copper wires of standard wire diameters suitable for different specifications of wires and cables, wire drawing equipment is usually used nowadays to draw copper wires into various required specifications.

[0003] After retrieval, such as the Chinese publicly authorized patent "Wire drawing machine for copper wire processing", the publication number is "CN218982706U". This patent realizes the cooling of the wire drawing die by setting a cooling and flushing structure and a spray pipe. When in use, one end of the copper wire on the wire drawing roller passes through the wire drawing die until it reaches another set of wire drawing rollers. It can be seen that when the existing copper wire drawing equipment is working, first, the copper wire is pulled out from the wire drawing roller for wire feeding, and then, the copper wire passes through the wire drawing die and is wound on the wire drawing roller for wire taking. Then, the wire drawing roller for wire taking rotates, so that the copper wire on the wire drawing roller for wire feeding passes through the wire drawing holes with gradually decreasing inner diameters inside the wire drawing die, and then undergoes plastic deformation, and finally is gradually wound on the surface of the wire drawing roller for wire taking. Through the above actions, the wire drawing operation of the copper wire is realized. However, in the above process, due to a certain distance between the wire drawing roller for wire taking and the wire drawing die, the copper wire at the position between the two is easily affected by external factors (such as air flow), and thus shakes. Since one end of the copper wire at this position enters the wire drawing die and undergoes plastic deformation, the shaking copper wire will generate a deflecting force on the copper wire entering the wire drawing die, resulting in the copper wire at this position being prone to breakage, thereby affecting the processing efficiency of the copper wire. Summary of the Invention

[0004] In order to solve the technical problems existing in the above background technique, the present invention provides a thick copper wire drawing device for vehicle-grade high-power devices, including: two relatively arranged first winding machines and second winding machines. A wire drawing machine is arranged between the first winding machine and the second winding machine. The first winding machine is wound with a to-be-processed thick copper wire. One end of the to-be-processed thick copper wire enters the wire drawing machine, and after being processed, the copper wire after wire drawing is obtained. The copper wire after wire drawing is wound onto the second winding machine; The wire drawing machine includes a guiding mechanism, a cleaning mechanism, and a wire drawing mechanism arranged in sequence. There are two guiding mechanisms, which are respectively located at the inlet and outlet of the wire drawing machine; the cleaning mechanism is installed at the inlet of the wire drawing machine to clean and disinfect the incoming to-be-processed thick copper wire. The to-be-processed thick copper wire after cleaning enters the wire drawing mechanism for wire drawing and then is wound onto the second winding machine under the guidance of the guiding mechanism at the outlet.

[0005] The guiding mechanism includes a guiding frame, guiding rollers, and a guiding robotic arm. One end of the guiding robotic arm is arranged on one side of the wire drawing machine, the other end of the guiding robotic arm is connected to the guiding frame, multiple guiding rollers are provided and are installed on the guiding frame in an array. A detection camera is also arranged on the guiding robotic arm, which is used to obtain the real-time image of the guiding frame and transmit it to the background controller. The background controller processes the real-time image and compares the image of the copper wire after wire drawing with the qualified shape. If it does not meet the standard, the equipment is repaired in a timely manner to reduce losses; if the copper wire deviates from the guiding rollers during the processing, timely adjustment or shutdown for repair can also be carried out using the real-time image.

[0006] The cleaning mechanism includes a cleaning cylinder. The cleaning cylinder is divided into a sterilization area and a cleaning area by a partition. An inlet cavity is provided on the side wall of the sterilization area close to the side wall of the cleaning cylinder, and a rotating roller is rotatably connected to the side wall. On the symmetric inner walls of the cleaning area, mounting plates are fixedly connected. Cleaning cotton blocks are installed on the mounting plates. A cleaning rotating wheel is provided at a set distance from the cleaning cotton blocks. An outlet cavity is provided on the side wall of the cleaning cylinder close to the side wall of the cleaning cylinder. A waste liquid receiving pool is fixedly connected to the outer side wall of the cleaning cylinder on one side of the outlet cavity. The rotating roller disinfects and sterilizes the thick copper wire through the sterilization area, and the thick copper wire is cleaned by the mutual friction between the cleaning rotating wheel and the cleaning cotton blocks, with thorough cleaning.

[0007] The wire drawing mechanism includes multiple levels of wire drawing modules. The multiple levels of wire drawing modules are formed by arranging multiple wire drawing modules in sequence. Each wire drawing module includes two winding cone wheels. A wire drawing die is arranged between the two winding cone wheels. A tension pulley is also arranged on one side of the winding cone wheel. The copper wire is stretched into a set specification size after passing through the wire drawing die, and the stretched copper wire is polished using a grinding wheel. A heat dissipation interlayer for accommodating coolant is provided behind each grinding wheel. The heat dissipation interlayer is connected to a heat dissipation pipeline to form a circulation loop. The heat dissipation interlayer is used to cool the polished copper wire. After passing through the heat dissipation interlayer, the copper wire enters the next set of wire drawing modules for stretching. The multiple levels of wire drawing modules can achieve the hierarchical stretching of the thick copper wire and can smoothly complete the wire drawing work of the copper wire.

[0008] The first winding machine includes a base, on which a slide rail is installed. A first slider and a second slider are arranged on the slide rail. A plurality of bobbin mounting wheels are arranged on the inner sides of the first slider and the second slider. Bobbins are arranged on the bobbin mounting wheels, and copper wires are wound on the bobbins. At least one end of one of the bobbin mounting wheels is connected to a winding motor, which is used to drive the bobbin mounting wheel to rotate, thereby driving the bobbin to rotate. A tread made of rubber material is sleeved on the surface of the bobbin mounting wheel to increase the friction force. And when the resistance of the bobbin is large, the bobbin mounting wheel can slide relative to the bobbin to avoid breaking the copper wire; Limiting blocks are arranged on the right side surfaces of the first slider and the second slider, and the limiting blocks can limit the bobbins to ensure the rotational stability of the bobbins. A semi-circular limiting groove is arranged at the bottom of the limiting block, and the rotating shaft of the bobbin can be fitted in the limiting groove to ensure the rotational stability of the rotating shaft. The limiting block can also adjust its own height by using a limiting motor to cooperate with bobbins of different sizes.

[0009] Driving mechanisms are arranged at the bottoms of the first slider and the second slider. The driving mechanisms include driving motors and lead screws. The driving motors drive the lead screws to rotate. The lead screws are installed at the bottoms of the first slider and the second slider. The rotation of the lead screws can drive the first slider and the second slider to move along the slide rail, enabling the first winding machine to move along the slide rail during the winding process. The controller can be pre-programmed to adjust the moving speeds of the first slider and the second slider according to the winding speed. During use, the first bobbin mounting wheel and the second bobbin mounting wheel cooperate to clamp the bobbin. The driving mechanism drives the first slider and the second slider to move along the slide rail, and the copper wire follows the first slider and the second slider to move along the slide rail, which is beneficial for the thick copper wire to be drawn to smoothly transition from one end of the bobbin to the other end during the winding process, ensuring that the thick copper wire to be drawn is wound neatly; The first winding machine is used to release the thick copper wire to be drawn, and the second winding machine is used to wind the thick copper wire after drawing is completed; The structures of the second winding machine and the first winding machine are the same.

[0010] The beneficial effects of the present invention are as follows: 1. The present invention provides a thick copper wire drawing device for vehicle-grade high-power devices. Two relatively arranged first winding machines and second winding machines are adopted. Since there is a certain distance between the winding machine and the drawing die, the copper wire at the position between the two is easily affected by external factors and thus shakes. Therefore, the present invention sets a driving structure for the bobbin mounting wheel, and the bobbin mounting wheel can slide relative to the bobbin to avoid breaking the copper wire.

[0011] 2. The present invention adopts a guiding mechanism and a slider that can adjust the position of the winding machine in cooperation with it, which can make the copper wire entering the inside of the drawing machine relatively stable and reduce the angular deviation of the copper wire. The copper wire entering the drawing machine first passes through a cleaning mechanism. During this process, multiple groups of pulleys arranged in the cleaning mechanism can be used to position the copper wire, and the influence of external factors can also be significantly reduced during the process of passing through the cleaning mechanism.

[0012] 3. The present invention adopts multi-stage stretching during the wire drawing process, and performs grinding and cooling treatment each time to reduce the influence of temperature on the wire drawing process. Moreover, each grinding process can significantly improve the wire drawing accuracy, ensure that the copper wire after step-by-step stretching meets the processing requirements, reduce the influence of plastic deformation, and effectively avoid the fracture of the copper wire during step-by-step stretching, thereby improving the processing efficiency and accuracy of the copper wire.

[0021] Example 1, as Figures 1-4 shown, this embodiment provides a thick copper wire drawing device for automotive-grade high-power devices, including: two relatively arranged first winding machines 1 and second winding machines 3. A wire drawing machine 2 is arranged between the first winding machine 1 and the second winding machine 3. A to-be-processed thick copper wire is wound around the first winding machine 1. One end of the to-be-processed thick copper wire enters the wire drawing machine 2, and after being processed, the copper wire after wire drawing is wound onto the second winding machine 3. The wire drawing machine 2 includes a guiding mechanism 21, a cleaning mechanism, and a wire drawing mechanism arranged in sequence. There are two guiding mechanisms 21, which are respectively located at the inlet and outlet of the wire drawing machine 2. The cleaning mechanism is installed at the inlet of the wire drawing machine 2 to clean and disinfect the incoming to-be-processed thick copper wire. The to-be-processed thick copper wire after cleaning enters the wire drawing mechanism for wire drawing and is then wound onto the second winding machine 3 under the guidance of the guiding mechanism 21 at the outlet.

[0022] The guiding mechanism 21 includes a guiding frame 202, guiding rollers 201 and a guiding robotic arm 203. One end of the guiding robotic arm 203 is arranged on one side of the wire drawing machine 2, and the other end of the guiding robotic arm 203 is connected to the guiding frame 202. A plurality of guiding rollers 201 are provided and are installed on the guiding frame 202 in an array.

[0023] The cleaning mechanism includes a cleaning cylinder 24. The cleaning cylinder 24 is divided into a sterilization area and a cleaning area by a partition 25. The sterilization area is close to the side wall of the cleaning cylinder 24 and is provided with an inlet cavity. A plurality of rotating rollers 22 are rotatably connected to the side wall. The inner walls of the cleaning area are symmetrically fixedly connected with mounting plates, and cleaning cotton blocks 23 are installed on the mounting plates. A cleaning rotating wheel is arranged at a set distance from the cleaning cotton blocks 23. The cleaning area is close to the side wall of the cleaning cylinder 24 and is provided with an outlet cavity. A waste liquid receiving pool is fixedly connected to the outer side wall of the cleaning cylinder 24 on one side of the outlet cavity. The rotating rollers 22 sterilize and disinfect the thick copper wire through the sterilization area, and the cleaning rotating wheel and the cleaning cotton blocks 23 rub against each other to clean the thick copper wire, achieving thorough cleaning.

[0024] The wire drawing mechanism includes a box body. A multi-stage wire drawing module is arranged in the box body. The multi-stage wire drawing module is formed by sequentially arranging a plurality of wire drawing modules 28. Each wire drawing module 28 includes two winding cone wheels 27 and a grinding wheel 26. A wire drawing die 29 is arranged between the two winding cone wheels 27. The wire drawing die 29 is installed on the inner side surface of the box body through a card slot; a tension pulley is also arranged on one side of the winding cone wheel 27, which is used to tension the copper wire. The copper wire is stretched into a set specification size after passing through the wire drawing die 29, and the stretched copper wire is polished by the grinding wheel 26. A heat dissipation interlayer for accommodating coolant is arranged behind each grinding wheel 26. The heat dissipation interlayer is connected to a heat dissipation pipeline to form a circulation loop. The heat dissipation interlayer is used to cool the polished copper wire. After the copper wire passes through the heat dissipation interlayer, it enters the next set of wire drawing modules 28 for stretching. The multi-stage wire drawing module can achieve hierarchical stretching of the thick copper wire and can smoothly complete the wire drawing work.

[0025] The first coiling machine 1 includes a base 11, on which a slide rail is installed. A first slider 12 and a second slider 13 are arranged on the slide rail. A plurality of bobbin mounting wheels are arranged on the inner sides of the first slider 12 and the second slider 13. A bobbin 15 is arranged on the bobbin mounting wheels, and copper wire is wound on the bobbin 15. One end of at least one bobbin mounting wheel is connected to a winding motor, and the winding motor is used to drive the bobbin mounting wheel to rotate, so as to drive the bobbin 15 to rotate. A tread made of rubber material is sleeved on the surface of the bobbin mounting wheel to increase the friction force. And when the resistance of the bobbin 15 is large, the bobbin mounting wheel can slide relative to the bobbin 15 to avoid breaking the copper wire. A limiting block 14 is arranged on the right side surfaces of the first slider 12 and the second slider 13. The limiting block 14 can limit the bobbin 15 to ensure the rotation stability of the bobbin 15. A semi-circular limiting groove is arranged at the bottom of the limiting block 14, and the rotating shaft of the bobbin 15 can be fitted in the limiting groove to ensure the rotation stability of the rotating shaft. The limiting block 14 can also adjust its own height by using a limiting motor to cooperate with bobbins 15 of different sizes.

[0026] Driving mechanisms are arranged at the bottoms of the first slider 12 and the second slider 13. The driving mechanisms include driving motors and lead screws. The driving motors drive the lead screws to rotate. The lead screws are installed at the bottoms of the first slider 12 and the second slider 13. The rotation of the lead screws can drive the first slider 12 and the second slider 13 to move along the slide rail, enabling the first coiling machine 1 to move along the slide rail during the winding process. The controller can be pre-programmed to adjust the moving speeds of the first slider 12 and the second slider 13 according to the winding speed. During use, a plurality of bobbin mounting wheels cooperate to support and drive the bobbin 15. The winding motor drives the bobbin mounting wheel to rotate, and the driving mechanism drives the first slider 12 and the second slider 13 to move along the slide rail. The bobbin follows the first slider 12 and the second slider 13 to move along the slide rail, which is beneficial for the rough copper wire to be drawn to smoothly transition from one end of the bobbin 15 to the other end during the winding process, ensuring that the rough copper wire to be drawn is wound neatly. Among them, the first coiling machine 1 is used to release the rough copper wire to be drawn, and the second coiling machine 3 is used to wind the rough copper wire after drawing is completed. The structures of the second coiling machine 3 and the first coiling machine 1 are the same.

[0027] First, wind the rough copper wire to be drawn that needs to be drawn on the first coiling machine 1, then perform pre-drawing treatment on the copper wire of the rough copper wire to be drawn, and sequentially pass through the guiding mechanism 21, the cleaning mechanism and the drawing mechanism arranged on the drawing machine 2, and finally fix the copper wire on the second coiling machine 3. Then, start the power supply of the winding motor to enable the two coiling machines to transfer the copper wire.

[0028] During the transfer of the copper wire, it first passes through the cleaning mechanism. When the thick copper wire to be drawn enters the cleaning mechanism through one of the wire passing ports, it passes through the rotating roller 22 and then leaves the cleaning mechanism through another wire passing port. During this period, the thick copper wire to be drawn is always immersed in the chemical cleaning agent in the sterilization area of the cleaning cylinder. Through the tight pressing of the rotating roller 22, the thick copper wire to be drawn comes into full contact and friction with the chemical cleaning solution, thereby removing the oxide layer on the surface of the thick copper wire to be drawn and preventing these oxide layers from damaging the wire drawing die 29 during the wire drawing process.

[0029] After the copper wire leaves the sterilization area of the cleaning cylinder, the thick copper wire to be drawn with the oxide layer on its surface washed off in the cleaning area of the cleaning cylinder enters the wire passing groove through one of the L-shaped wire passing ports. The water in the liquid storage cavity of the cleaning area is heated by the heat from the heat dissipation sandwich layer of the cleaning area. The water in the liquid storage cavity expands due to heat and rises into the wire passing groove. The hot water in the wire passing groove washes off the oily substances on the surface of the thick copper wire to be drawn. The thick copper wire to be drawn with the surfactant and corrosion inhibitor washed off is wiped clean by the cleaning rotating wheel and the cleaning cotton block 23 and then enters the wire drawing mechanism for wire drawing treatment.

[0030] A thick copper wire drawing device for vehicle-grade high-power devices in this embodiment uses two relatively arranged first winding machines 1 and second winding machines 3. Since there is a certain distance between the winding machine and the wire drawing die, the copper wire at the position between them is easily affected by external factors and thus shakes. Therefore, this embodiment sets a guiding mechanism 21 and a slider that can adjust the position of the winding machine in cooperation with it, which can make the copper wire entering the wire drawing machine 2 relatively stable and reduce the angular deviation of the copper wire. The copper wire entering the wire drawing machine 2 first undergoes treatment by the cleaning mechanism. During this process, multiple groups of pulleys set in the cleaning mechanism can be used to position the copper wire. The treatment process by the cleaning mechanism can also significantly reduce the influence of external factors. Then, during the wire drawing process, multi-stage stretching is carried out, and each time it is polished and cooled to reduce the influence of temperature on the wire drawing process. And each polishing process can significantly improve the wire drawing accuracy, ensure that the copper wire after multi-stage stretching meets the processing requirements, reduce the influence of plastic deformation, and multi-stage stretching effectively avoids copper wire breakage and improves the processing efficiency and accuracy of the copper wire.

[0031] The above are only the preferred embodiments of the present invention and are not used to limit the present invention. For those skilled in the art, the present invention can have various changes and modifications. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
