Description

Technical Field

[0001] The invention relates to the technical field of wire and cable manufacturing, and more specifically to a wire drawing device for manufacturing rare earth aluminum alloy cables. Background Art

[0002] Cable wire drawing equipment uses tensile force to deform metal materials along the stretching direction, thereby drawing metal materials into filaments. Cable wire drawing equipment can realize a continuous and automated production process, greatly improving production efficiency. Compared with traditional manual wire drawing or semi-automatic equipment, especially in the manufacturing process of rare earth aluminum alloy cables, more rare earth aluminum alloy filaments can be produced in a shorter time to meet the market's large demand for products.

[0003] In the process of drawing rare earth aluminum alloy cables, it is usually necessary to preheat the rare earth aluminum alloy cables to reduce the hardness of the rare earth aluminum alloy cables, improve plasticity, reduce thermal stress, improve processing accuracy and eliminate structural inhomogeneity.

[0016] Compared with the prior art, the present invention has the following beneficial effects:

[0017] (1) This scheme can expel the oxygen inside the preheating chamber by injecting nitrogen produced by a nitrogen generator into the preheating chamber, thereby creating a low-oxygen environment in the subsequent heating step. When the heating coil preheats the cable, the oxygen concentration is reduced, which greatly reduces the chance of direct contact between oxygen and the surface of the cable. By reducing the direct exposure of oxygen to the surface of the cable, the occurrence of oxidation during the preheating process of the cable can be effectively reduced, thereby improving the quality of the preheating process of the cable and effectively slowing down the oxidation rate of the cable surface.

[0018] (2) This solution uses a reset spring to drive four sealing plates to fit tightly to the surface of the cable. When the cable passes through the preheating chamber, the sealing plate reduces the gap width between the cable and the preheating chamber, effectively reducing the entry of oxygen from the outside of the preheating chamber and the leakage of nitrogen from the inside. This significantly reduces nitrogen consumption and further enhances the anti-oxidation effect during the cable preheating stage.

[0019] (3) This solution uses rotating fan blades to evenly blow the high-temperature nitrogen in the preheating chamber to the surface of the cable, which can cool the cable after the wire drawing operation is completed. Since the nitrogen has a high temperature, it will not quickly lower the temperature of the cable surface to an excessively low level, preventing the internal stress of the cable from increasing sharply due to the direct use of water cooling in the subsequent cooling stage, causing the cable to crack, thereby damaging its structural integrity and expected service life. In addition, it effectively prevents the high-temperature cable from directly contacting the cooling liquid and exacerbating the oxidation reaction, further reducing the oxidation phenomenon on the cable surface, and ensuring the quality and performance of the cable during the cooling process.

[0020] (4) In this solution, the outlet nozzle swings during the process of nitrogen delivery to the diversion chamber, which increases the diffusion area of ​​nitrogen and controls the diffusion direction of nitrogen, effectively reducing the possibility of oxygen contacting the cable. In addition, when nitrogen is discharged from the outlet nozzle, it will be blocked by the diffusion plate, which can disperse the nitrogen into a finer airflow, further increasing the diffusion area of ​​nitrogen and improving its distribution uniformity, further enhancing the anti-oxidation effect of the cable during the wire drawing process.

[0021] (5) In this solution, the two grinding knives rotate while the cable continues to move, which can peel off and remove the oxide layer on the surface of the cable, thereby reducing the residual oxide layer. Since the oxide layer has been reduced by reducing oxygen, the wear and tear on the cable body is also reduced when the oxide layer is cleaned, which reduces the impact of oxidation on material loss and quality during the cable processing process.

DETAILED DESCRIPTION

[0034] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0035] See also Figure 1 , Figure 2 , Figure 3 , Figure 7 and Figure 8 A wire drawing device for manufacturing rare earth aluminum alloy cables, comprising a wire drawing component 1, a traction component 2 and a cable line 3, wherein the traction component 2 is used to provide traction for the cable line 3, and the wire drawing component 1 is used to perform wire drawing on the cable line 3, and an oxygen exhaust mechanism is arranged on the side of the wire drawing component 1, and the oxygen exhaust mechanism includes a preheating chamber 402 connected to the left side of the wire drawing component 1 and a nitrogen generator 401 for generating nitrogen, a heating coil 405 is fixedly connected to the interior of the preheating chamber 402, and a controller 404 is fixedly connected to the lower left side of the wire drawing component 1, and the heating coil 405 is electrically connected to the controller 404, and the controller 404 is used to control the heating coil 405 to heat the cable line 3, so as to realize preheating of the cable line 3.

[0036] Among them, a nitrogen inlet pipe 403 is provided on the lower surface of the preheating chamber 402, and the nitrogen inlet pipe 403 is fixedly connected to the nitrogen generator 401. The inner wall of the side end of the preheating chamber 402 is rotatably connected to the second rotating shaft 704, and the surface of the second rotating shaft 704 is fixedly connected to the sealing plate 701. The front end of the nitrogen generator 401 is fixedly connected to a cable support tube 406 that matches the cable 3 to support the cable 3 to prevent the cable 3 from being supported down and pressed on the sealing plate 701, causing the sealing plate 701 to be distorted and deflected and affecting the sealing effect. The inner and outer walls of the left side of the preheating chamber 402 are equidistantly fixedly connected with brackets 702, and a return spring 703 is fixedly connected between the bracket 702 and the sealing plate 701, which can push the four sealing plates 701 to fit the surface of the cable 3 respectively. The number of the sealing plates 701 is four, which can reduce the size of the gap between the cable 3 and the preheating chamber 402, and reduce the entry of oxygen and the outflow of nitrogen.

[0037] The side where the preheating chamber 402 is located in the wire drawing component 1 is the left side, and similarly, the other side of the wire drawing component 1 is the right side. Therefore, by adopting the above technical solution, when the cable 3 is subjected to the wire drawing process, the cable 3 is passed through the wire drawing component 1 and connected to the traction component 2, and the cable 3 can be driven by the traction component 2 to pass through the cable support tube 406. During this period, the cable 3 is supported by the cable support tube 406 to prevent the cable 3 from being supported down and pressed on the sealing plate 701, causing the sealing plate 701 to be distorted and deflected and affecting the sealing effect. The cable 3 then passes through the preheating chamber 402, and is heated by the heating coil 405 to achieve preheating of the cable 3. After the cable 3 enters the wire drawing component 1, the wire drawing operation of the cable 3 is achieved through the wire drawing component 1, wherein the controller 404 can be the existing technology, for example, the controller 404 can adopt Deutronic's D-Sinus controller 404, and the embodiment of the present application does not specifically limit the controller 404.

[0038] When the cable 3 is preheated, the nitrogen generated by the nitrogen generator 401 is slowly injected into the preheating chamber 402 through the nitrogen input pipe 403, and as the nitrogen is input, the oxygen inside the preheating chamber 402 is gradually discharged. In this way, when the cable 3 is heated by the heating coil 405, the discharge of oxygen can reduce the direct contact between the oxygen and the surface of the cable 3, thereby reducing the occurrence of surface oxidation of the cable 3 during the preheating process of the cable 3.

[0039] Since different types of cables 3 need to be transported, a gap is left between the cable 3 and the preheating chamber 402, and the nitrogen inside the preheating chamber 402 will flow out. Therefore, when the cable 3 passes through the preheating chamber 402, the cable 3 is located between the four sealing plates 701. Since the reset spring 703 can push the four sealing plates 701 to fit the surface of the cable 3, the gap between the cable 3 and the preheating chamber 402 can be reduced by the four sealing plates 701 during the process of the cable 3 passing through the preheating chamber 402, and the movement of the cable 3 is not affected, thereby reducing the entry of oxygen from the outside of the preheating chamber 402 and the outflow of nitrogen from the inside, reducing nitrogen consumption while further improving the anti-oxidation effect of the cable 3 during the preheating process.

[0040] like Figure 2 and Figure 4 As shown, a cooling mechanism is provided between the preheating chamber 402 and the wire drawing assembly 1, and the cooling mechanism includes a nitrogen delivery pipe 502 connected to the upper surface of the preheating chamber 402, and the lower end of the nitrogen delivery pipe 502 is connected to a windproof chamber 507, which can reduce the probability of direct contact between the nitrogen with a higher temperature and the first motor 505, and reduce the influence of high temperature on the first motor 505. The windproof chamber 507 is fixedly connected to the first motor 505, and the output shaft of the first motor 505 is fixedly connected to the fan blade 504, which is driven by the first motor 505 to rotate, so that the nitrogen can be transported. The right side of the wire drawing component 1 is connected to a cooling chamber 501, and the nitrogen delivery pipe 502 is fixedly inserted into the interior of the cooling chamber 501. One end of the nitrogen delivery pipe 502 that passes through the interior of the cooling chamber 501 is connected to an annular air outlet pipe 508. An air outlet is provided on the inner circle surface of the annular air outlet pipe 508. There are multiple air outlets, and the multiple air outlets are evenly arranged on the inner circle surface of the annular air outlet pipe 508. Since the temperature of nitrogen is higher than that of the external air and lower than that of the heated cable 3, the higher temperature nitrogen can be evenly sprayed on the surface of the cable 3 to cool the cable 3.

[0041] Among them, the lower surface of the cooling chamber 501 is connected with a nitrogen output pipe 503, and the nitrogen can be transported back to the preheating chamber 402 through the nitrogen output pipe 503 to reduce the loss and waste of nitrogen. The nitrogen output pipe 503 is connected to the nitrogen input pipe 403, and the inner wall of the nitrogen delivery pipe 502 is fixedly connected with a guide plate 506, which can prevent the higher temperature nitrogen from directly contacting the first motor 505, causing the temperature of the first motor 505 to be too high and affecting the use of the first motor 505.

[0042] By adopting the above technical solution, when the nitrogen enters the preheating chamber 402, the cable 3 is preheated, and the heat generated during the preheating process will also heat the nitrogen. At this time, the fan blades 504 are driven to rotate by the first motor 505, wherein the first motor 505 is a high-temperature resistant motor. The nitrogen in the preheating chamber 402 is transported to the nitrogen delivery pipe 502 through the rotating fan blades 504, and discharged through the annular air outlet pipe 508. Since a plurality of air outlets are evenly arranged on the annular air outlet pipe 508, the nitrogen with a higher temperature can be evenly sprayed on the surface of the cable 3, and the cable 3 can be cooled after the wire drawing operation is completed. Since the temperature of nitrogen is relatively high, the surface temperature of the cable 3 will not drop too low quickly. In this way, in the subsequent cooling process, it is avoided that the cable 3 is directly cooled by water cooling, which may increase the internal stress of the cable 3 and cause cracking, affecting the integrity and service life of the cable 3. It also prevents the high-temperature cable 3 from directly contacting the cooling liquid or air to produce more oxidation reactions, further reducing the oxidation phenomenon of the cable 3.

[0043] As nitrogen is continuously input into the cooling chamber 501, the purpose of nitrogen transportation can be achieved through the fan blades 504. During the nitrogen transportation process, the pressure in the nitrogen output pipe 503 is also relatively large. Therefore, the nitrogen in the nitrogen output pipe 503 eventually moves upward, and the nitrogen in the nitrogen input pipe 403 eventually moves to the upper and lower ends. The nitrogen moving downward will eventually be driven upward by the nitrogen in the nitrogen output pipe 503. Therefore, it can be ensured that the nitrogen in the nitrogen input pipe 403 does not flow into the nitrogen output pipe 503, so that the nitrogen is transported back to the preheating chamber 402 through the nitrogen output pipe 503, reducing the loss and waste of nitrogen. In the process of nitrogen flowing in the nitrogen delivery pipe 502, the guide plate 506 can prevent the nitrogen with higher temperature from directly contacting the first motor 505, causing the temperature of the first motor 505 to be too high and affecting the use of the first motor 505.

[0044] like Figure 2 , Figure 3 , Figure 5 and Figure 6As shown, a diversion chamber 601 is fixedly inserted between the nitrogen inlet pipe 403 and the inner part of the lower surface of the preheating chamber 402, the inner wall of the diversion chamber 601 is rotatably connected with a first rotating shaft 610, the arc surface of the first rotating shaft 610 is fixedly connected with a rotating plate 606, the number of the rotating plates 606 is multiple, the front and rear ends of the first rotating shaft 610 are fixedly connected with a disk 609, the ends of the two disks 609 that are away from each other are fixedly connected with a guide rod 605, the front and rear ends of the diversion chamber 601 are rotatably connected with a swing arm 603, and an air outlet nozzle 602 is fixedly connected between the two swing arms 603. The swing of the air outlet nozzle 602 can increase the diffusion area and the specified diffusion direction of the nitrogen in the process of the nitrogen entering the air outlet nozzle 602 and being discharged.

[0045] Among them, a slide groove 607 is provided on the surface of the swing arm 603, and the guide rod 605 penetrates to the outside of the diversion bin 601 and is inserted into the inside of the slide groove 607. The inner wall of the diversion bin 601 is fixedly connected with a guide frame 604, and the airflow can flow to one side of the diversion bin 601 through the guidance of the guide frame 604. The right inner wall of the air outlet nozzle 602 is fixedly connected with a diffusion plate 608, and a plurality of through holes are evenly provided on the surface of the diffusion plate 608. In the process of nitrogen being discharged from the air outlet nozzle 602, the nitrogen can be broken up by blocking the diffusion plate 608, so as to further increase the nitrogen diffusion area and diffusion uniformity.

[0046] By adopting the above technical solution, when the nitrogen is transported to the preheating chamber 402 through the nitrogen inlet pipe 403, it will flow through the diversion chamber 601 and be discharged through the gas outlet nozzle 602. In the process of the nitrogen flowing through the diversion chamber 601, the guide frame 604 can guide the airflow to one side of the diversion chamber 601, thereby driving the rotating plate 606 to rotate. The rotation of the rotating plate 606 can drive the circular plate on the first rotating shaft 610 and its guide rod 605 to rotate. In the process of the guide rod 605 rotating, the guide rod 605 slides inside the slide groove 607. Thereby, the effect of guiding the swing arm 603 to swing up and down is achieved. As the swing arm 603 swings up and down, the air outlet nozzle 602 can be driven to swing. In this way, in the process of nitrogen entering the air outlet nozzle 602 and being discharged, the diffusion area and the specified diffusion direction of the nitrogen can be increased through swinging, thereby reducing the probability of oxygen contacting the cable 3. In the process of nitrogen being discharged from the air outlet nozzle 602, the nitrogen can be broken up through the blocking of the diffusion plate 608, thereby further increasing the nitrogen diffusion area and diffusion uniformity, and further improving the anti-oxidation effect during the wire drawing process of the cable 3.

[0047] like Figure 2 , Figure 4 , Fig. 9 and Fig.10As shown, an oxide layer removal mechanism is arranged inside the preheating chamber 402, and the oxide layer removal mechanism includes a second motor 802 fixedly connected to the outer surface of the preheating chamber 402, the output shaft of the second motor 802 penetrates into the preheating chamber 402 and is fixedly connected to a transmission gear 804, a hanger 805 is fixedly connected to the inner wall of the top of the preheating chamber 402, a support ring 801 is arranged inside the preheating chamber 402, an annular slide rail 806 is fixedly sleeved on the outer surface of the support ring 801, the hanger 805 is slidably connected to the surface of the annular slide rail 806, an outer gear ring 803 is fixedly sleeved on the right side of the support ring 801, the outer gear ring 803 is meshed with the transmission gear 804, the second motor 802 is used to drive the driving gear to rotate, and then the outer gear ring 803 is driven to rotate, so that the support ring 801 and its grinding knife 807 can be rotated.

[0048] Among them, the inner surface of the support ring 801 is fixedly connected with a guide rod 810, and the surface sliding sleeve of the guide rod 810 is provided with a grinding knife 807. When the cable 3 moves, the two grinding knives 807 rotate to remove the oxide layer on the surface of the cable 3. The upper and lower ends of the guide rods 810 that are close to each other are fixedly connected with a connecting square plate 809. A pressure spring 808 is fixedly connected between the connecting square plate 809 and the inner wall of the grinding knife 807. The pressure provided by the pressure spring 808 can push the grinding knife 807 to stick to the surface of the cable 3.

[0049] By adopting the above technical solution, when the cable 3 is subjected to wire drawing processing, the cable 3 is first preheated by the heating coil 405, and the residual oxygen that has not been completely discharged will still produce a thin oxide layer on the surface of the cable 3. Therefore, in the process of the cable 3 moving into the wire drawing assembly 1, the second motor 802 is used to drive the driving gear to rotate, and then the outer ring gear 803 is driven to rotate. As the outer ring gear 803 rotates, the support ring 801 and its grinding knife 807 can be rotated, and the pressure is provided by the pressure spring 808 to push the grinding knife 807 to the surface of the cable 3. Therefore, when the cable 3 moves, the two grinding knives 807 rotate, and the oxide layer on the surface of the cable 3 can be removed, thereby reducing the presence of the oxide layer on the surface of the cable 3. Moreover, since there is less oxide layer, when the oxide layer is cleaned, the wear and loss caused to the cable 3 is also smaller, thereby reducing the loss and quality impact caused by oxidation during the processing of the cable 3.

[0050] Instructions for use: The traction component 2 drives the cable 3 to pass through the cable support tube 406, and then the cable 3 passes through the preheating chamber 402, and the cable 3 is heated by the heating coil 405. After the cable 3 enters the wire drawing component 1, the wire drawing processing operation of the cable 3 is realized through the wire drawing component 1.

[0051] When the cable 3 is preheated, the nitrogen generated by the nitrogen generator 401 is slowly injected into the preheating chamber 402 through the nitrogen inlet pipe 403, and the oxygen inside the preheating chamber 402 is discharged.

[0052] When the nitrogen enters the preheating chamber 402, the fan blades 504 are driven to rotate by the first motor 505, and the nitrogen in the preheating chamber 402 is transported to the nitrogen delivery pipe 502 and sprayed on the surface of the cable 3. As the nitrogen is continuously input into the cooling chamber 501, the nitrogen is transported back to the preheating chamber 402 through the nitrogen output pipe 503.

[0053] When nitrogen is transported to the preheating chamber 402 through the nitrogen inlet pipe 403 , it flows through the diversion chamber 601 . In the process of nitrogen flowing through the diversion chamber 601 , the gas outlet nozzle 602 is driven to swing, and the nitrogen is discharged through the gas outlet nozzle 602 .

[0054] The above is only a preferred specific implementation of the present invention; however, the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical solution and its improved conception within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
