Description

Technical Field

[0001] The present invention relates to the technical field of copper wire annealing, and in particular to conductor processing equipment and technology for high-voltage cables on board new energy vehicles. Background Art

[0002] The high-voltage cables for new energy vehicles use copper wire as the core of the cable. Before the copper wire becomes the core of the cable, it needs to go through a series of processes, including smelting, refining, forming, drawing, annealing and winding of the copper raw materials. The annealing of the copper wire is mainly to eliminate the stress generated by the copper wire during the drawing process. Annealing can eliminate the grain defects and impurities in the copper wire, improve the integrity of its lattice structure, and thus improve the conductivity. It can also remove stress, improve the ductility, strength and plasticity of the copper wire, improve its mechanical properties, and reduce the risk of breakage.

[0003] For example, in the Chinese patent application document with publication number CN106755928A and titled Large Diameter Brass Wire Annealing Machine, the copper wire that needs to be annealed is pulled out from the wire drawing machine and sequentially passes through the preheating wheel, the first guide wheel, the regulating wheel, the first annealing wheel, the steam protection tank, the second annealing wheel in the steam protection box, the steam tank, the third annealing wheel in the annealing water tank, the cooling water tank, the fourth annealing wheel and the third guide wheel in the cooling water tank, the drying device, the second guide wheel and the outlet wheel. The copper wire that does not need to be annealed is pulled out from the wire drawing machine and sequentially passes through the front wire wheel, the rear wire wheel and the wire wheel.

[0004] Regarding the above-mentioned related technologies, during the preheating process of the copper wire, the preheating wheel abuts against the copper wire to preheat one side of the copper wire, which may cause a temperature difference between the side of the copper wire in contact with the preheating wheel and the side of the copper wire away from the preheating wheel, thereby causing uneven preheating of the copper wire, which is not conducive to the subsequent annealing of the copper wire. In addition, during the annealing process, water vapor will permeate the entire annealing machine casing. After the annealing machine stops working, the water vapor will contact the parts inside the casing, thereby corroding the mechanical parts, which is not conducive to the stable annealing function of the copper wire. Summary of the invention

DETAILED DESCRIPTION

[0037] To make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the following will be combined with the embodiments of the present invention. Figure 1-Figure 8 , the technical scheme of the embodiment of the present invention is clearly and completely described. Obviously, the described embodiment is a part of the embodiment of the present invention, not all of the embodiments. Based on the described embodiment of the present invention, all other embodiments obtained by ordinary technicians in this field belong to the scope of protection of the present invention.

[0038] In the first aspect, this embodiment provides a conductor processing device for high-voltage cables on new energy vehicles, referring to Figure 1 and Figure 2 , the conductor processing equipment for high-voltage cables on new energy vehicles includes a housing 1, a first annealing shell 2, a steam shell 3, a second annealing shell 4, a cooling shell 5, a first annealing wheel 21 and a second annealing wheel 41. The first annealing shell 2, the steam shell 3 and the second annealing shell 4 are fixedly arranged inside the housing 1 from top to bottom, the cooling shell 5 is arranged outside the side wall of the second annealing shell 4, and the cooling shell 5 is filled with coolant. The copper wire 9 passes through the first annealing shell 2, the steam shell 3, the second annealing shell 4 and the cooling shell 5 in sequence. The first annealing wheel 21 is rotatably connected to the inside of the first annealing shell 2, the second annealing wheel 41 is rotatably connected to the inside of the second annealing shell 4, the copper wire 9 is wound around the outer side of the first annealing wheel 21 and the second annealing wheel 41, and the outside of the housing 1 has a driving source for pulling the copper wire 9 to move, which is the prior art. The first annealing wheel 21 and the second annealing wheel 41 heat the copper wire 9 to perform an annealing process on the copper wire 9, and the annealed copper wire 9 is transported to the cooling shell 5 to contact the coolant and be cooled.

[0039] Reference Figure 3 , Figure 4 and Figure 5 A partition 22 is fixedly connected to the first annealing shell 2, and the partition 22 divides the first annealing shell 2 into an upper gas delivery area 23, a lower gas delivery area 24, a gas outlet area 25 and an annealing area 26. The first annealing wheel 21 is located in the annealing area 26, and the lower gas delivery area 24 is connected to the steam shell 3. A preheating pipe 27 is fixedly connected between the upper gas delivery area 23 and the lower gas delivery area 24. The preheating pipe 27 is spiral and is arranged on the outer side of the copper wire 9 and extends along the axial direction of the copper wire 9.

[0040] Reference Figure 5 and Figure 6 The upper gas delivery area 23 is connected to the gas outlet area 25 through the gas delivery groove 221. The side wall of the first annealing shell 2 is fixedly connected with an outlet pipe 28 connected with the inside of the gas outlet area 25. The copper wire 9 is slidably arranged in the outlet pipe 28. The side wall of the outlet pipe 28 is fixedly connected with an exhaust pipe 29 for discharging water vapor from the casing 1.

[0041] The coolant in the cooling shell 5 flows into the second annealing shell 4 and contacts the second annealing wheel 41. The coolant contacts the high-temperature second annealing wheel 41 and evaporates into water vapor and moves upward. The water vapor moves to the lower gas delivery area 24 through the steam shell 3. The water vapor in the lower gas delivery area 24 passes through the preheating pipe 27, the upper gas delivery area 23, the gas delivery groove 221, the gas outlet area 25, the gas outlet pipe 28 and the exhaust pipe 29 in sequence and is discharged to the outside of the casing 1.

[0042] The partition 22 separates the lower gas delivery area 24 from the annealing area 26, preventing water vapor from entering the annealing area 26 and contacting the first annealing wheel 21, reducing the erosion of the first annealing wheel 21 by water vapor, and using the preheating tube 27 to transport high-temperature water vapor to the preheating tube 27 to preheat the copper wire 9. In addition, the preheating tube 27 is arranged in a spiral shape and evenly arranged on the outer side of the copper wire 9, so that the outer side of the copper wire 9 can receive the heat energy of the preheating tube 27, instead of using the preheating wheel to heat only one side of the copper wire 9, while improving the uniformity of heating the copper wire 9 during the preheating process, the utilization efficiency of the heat energy of the second annealing wheel 41 is improved.

[0043] The water vapor in the preheating tube 27 enters the upper gas transmission area 23, and enters the gas outlet pipe 28 after being heated again by the first annealing wheel 21 when flowing through the gas outlet area 25, so that the gas outlet pipe 28 and the preheating tube 27 cooperate to preheat the copper wire 9. The preheating tube 27 is arranged outside the gas outlet pipe 28 to reduce the heat dissipated by the water vapor in the gas outlet pipe 28 to the outside, thereby further improving the preheating effect on the copper wire 9.

[0044] Reference Figure 6The preheating tube 27 is connected in series with a control valve 271, and the control valve 271 is used to control the flow rate of water vapor in the preheating tube 27, thereby adjusting the heat transfer between the water vapor and the surface of the copper wire 9 and controlling the preheating temperature of the copper wire 9.

[0045] Reference Figure 7 The inner side of the air outlet area 25 is fixedly connected with a support plate 251, and the side wall of the air outlet pipe 28 is fixedly connected with a vent pipe 6, which is arranged in the support plate 251, and the bottom of the vent pipe 6 is closed, and the side wall of the vent pipe 6 is provided with an air delivery hole 61, and the outer side of the vent pipe 6 is slidably sleeved with a closing pipe 62 for closing the air delivery hole 61, and the outer side of the closing pipe 62 is fixedly connected with a transmission plate 63, and the transmission plate 63 abuts against the inner side of the air outlet area 25. The lower end of the vent pipe 6 is threadedly connected with a support nut 64 for supporting the closing pipe 62, and the outer side of the vent pipe 6 is fixedly sleeved with a limit ring 66, and the outer side of the vent pipe 6 is sleeved with an extrusion spring 65 for pushing the closing pipe 62 downward, and the extrusion spring 65 is located between the limit ring 66 and the transmission plate 63.

[0046] The water vapor in the outlet area 25 moves upward through the vent pipe 6 and enters the outlet pipe 28. During the upward movement of the water vapor, the transmission plate 63 is pushed upward. The closing tube 62 moves upward synchronously with the transmission plate 63, so that the closing tube 62 is separated from the air delivery hole 61. At the same time, the extrusion spring 65 is compressed by the transmission plate 63. At this time, the water vapor in the outlet area 25 enters the vent pipe 6 through the air delivery hole 61.

[0047] The water vapor in the outlet area 25 pushes the transmission plate 63 upward, and the extrusion spring 65 pushes the transmission plate 63 downward to increase the pressure of the water vapor in the outlet area 25, thereby increasing the flow rate of the water vapor flowing through the gas transmission hole 61. Since the end of the outlet pipe 28 away from the outlet area 25 is connected to the external atmosphere through the exhaust pipe 29, the temperature of the end of the outlet pipe 28 close to the exhaust pipe 29 is easily affected by the external atmosphere. Therefore, increasing the flow rate of water vapor in the gas transmission hole 61 can increase the flow rate of water vapor in the outlet pipe 28, reduce the amount of external atmosphere entering the outlet pipe 28 through the exhaust pipe 29, thereby reducing the influence of the external atmosphere on the temperature in the outlet pipe 28, and at the same time can slow down the corrosion of the copper wire 9 by the external atmosphere entering the outlet pipe 28 as an impurity gas.

[0048] Reference Figure 5 The inner side surfaces of the upper gas delivery zone 23 and the gas outlet zone 25 are fixedly connected with a heat conducting plate 7. Specifically, the side wall of the upper gas delivery zone 23 close to the annealing zone 26 and the side wall of the gas outlet zone 25 close to the annealing zone 26 are fixedly connected with the heat conducting plate 7, thereby improving the efficiency of heat transfer from the inside of the first annealing zone 26 to the upper gas delivery zone 23 and the gas outlet zone 25.

[0049] Reference Figure 1 and Figure 6The outer side of the outlet pipe 28 is fixedly connected with an insulation pipe 281, and the preheating pipe 27 is arranged between the outlet pipe 28 and the insulation pipe 281. The insulation pipe 281 can reduce the heat loss of water vapor inside the preheating pipe 27 and the outlet pipe 28, which is beneficial to the preheating effect of the preheating pipe 27 and the outlet pipe 28 on the copper wire 9.

[0050] Reference Figure 5 and Figure 8 The inner side of the annealing zone 26 is fixedly connected with a support shell 261, and the copper wire 9 slides through the support shell 261. A sealing ring 262 is fixedly connected inside the support shell 261, and the sealing ring 262 is slidably sleeved on the outer side of the copper wire 9. The support shell 261 is composed of a first shell 263 and a second shell 264. The first shell 263 is located between the lower gas transmission zone 24 and the annealing zone 26, and the second shell 264 is located between the outlet pipe 28 and the annealing zone 26. The copper wire 9 enters the annealing zone 26 through the first shell 263, and after being annealed by the first annealing wheel 21, it moves out of the annealing zone 26 through the second shell 264. Two sealing rings 262 are provided and are fixedly connected inside the first shell 263 and the second shell 264 respectively, so as to prevent water vapor in the lower gas transmission zone 24 and the outlet pipe 28 from entering the annealing zone 26.

[0051] Reference Figure 2 A liquid storage shell 8 is fixedly connected in the casing 1, and a support wheel 81 for supporting the copper wire 9 is rotatably connected in the liquid storage shell 8. The cooling shell 5 is fixedly connected between the liquid storage shell 8 and the second annealing shell 4, so that the coolant in the liquid storage shell 8 enters the second annealing shell 4 through the cooling shell 5. The cooling shell 5 is rectangular, so that the copper wire 9 is continuously in contact with the coolant during the process of moving from the second annealing wheel 41 to the support wheel 81, which increases the contact length of the copper wire 9 with the coolant and improves the cooling effect of the coolant on the copper wire 9.

[0052] Reference Figure 1 and Figure 2 A plurality of guide wheels 11 are rotatably connected inside the housing 1, and the copper wire 9 is wound around the outer side of the guide wheel 11. A sealing plate 12 is detachably connected to the housing 1, and the sealing plate 12 is used to prevent the external atmosphere from entering the housing 1 to oxidize the copper wire 9 being annealed, and at the same time, it is conducive to maintaining the annealing temperature inside the housing 1.

[0053] The implementation principle of the conductor processing equipment for high-voltage cables on new energy vehicles of the embodiment of the present invention is as follows: the coolant contacts the high-temperature second annealing wheel 41, evaporates into water vapor and moves upward, and the water vapor enters the preheating tube 27 through the steam shell 3 and the lower gas transmission area 24 in turn, and the spiral preheating tube 27 preheats the circumferential side of the copper wire 9. The water vapor in the preheating tube 27 enters the upper gas transmission area 23, and the water vapor in the upper gas transmission area 23 enters the gas outlet area 25, and the upper gas transmission area 23 is heated again by the first annealing wheel 21 when flowing through the gas outlet area 25. The water vapor in the gas outlet area 25 pushes the transmission plate 63 upward, the closing tube 62 and the transmission plate 63 move upward synchronously to separate from the gas transmission hole 61, and the extrusion spring 65 pushes the transmission plate 63 downward to increase the pressure of the water vapor in the gas outlet area 25, thereby increasing the flow rate of the water vapor flowing through the gas transmission hole 61 and the gas outlet pipe 28.

[0054] In a second aspect, an embodiment of the present invention provides a processing technology for processing a conductor for a high-voltage cable mounted on a new energy vehicle, which is applied to a conductor processing device for a high-voltage cable mounted on a new energy vehicle in the first aspect, and the processing technology is:

[0055] S1, the coolant contacts the high-temperature second annealing wheel 41 and evaporates into water vapor, which moves upward. The water vapor enters the preheating tube 27 through the steam shell 3 and the lower gas transmission area 24 in sequence. The spiral preheating tube 27 preheats the circumferential side of the copper wire 9;

[0056] S2, the water vapor in the preheating tube 27 enters the upper gas delivery zone 23, and the water vapor in the upper gas delivery zone 23 enters the gas outlet zone 25, and the upper gas delivery zone 23 is heated again by the first annealing wheel 21 when flowing through the gas outlet zone 25;
