[0002] Conductive wires are essential for electricity consumption and are widely used in various electronic systems, information transmission systems, mechanical equipment, and instrumentation systems in daily life and industrial production. Conductive wires, including enameled wire, electrical wires, and cables, are generally made of copper. During the production process, copper wire is typically drawn through a die to the desired diameter. During the drawing process, the copper wire undergoes cold working and plastic deformation, which causes internal grain fragmentation, lattice distortion, and residual internal stress. This process makes the copper wire susceptible to breakage. Therefore, high-temperature annealing of the cold-deformed copper wire increases the kinetic energy of its atoms and restores its properties.

DETAILED DESCRIPTION

[0022] Example 1

[0023] like Figure 1-Figure 3 As shown, the copper wire drawing annealing device for cable production proposed in this embodiment includes a processing box 3, an infusion device, two high-pressure nozzles 15, two left winding rollers 61 and two right winding rollers 62.

[0024] A right through-hole 301 and a left through-hole 302 are respectively provided on both sides of the processing box 3. The left through-hole 302 is only for two long-haired felts 7 to pass through so as to minimize the gap at the position of the left through-hole 302. A mounting bracket 23 is provided at the bottom end of the processing box 3, and the mounting bracket 23 is installed on the annealing furnace 1.

[0025] The two left winding rollers 61 and the two right winding rollers 62 are respectively arranged on the left and right sides of the processing box 3. The left winding roller 61 and the right winding roller 62 are both rotatably mounted on the mounting bracket 23. The processing box 3 is equipped with a first drive assembly for driving the two left winding rollers 61 to rotate synchronously. The first drive assembly includes a second servo motor 91 and two second gears 92. The two second gears 92 are respectively mounted on the ends of the two left winding rollers 61. The two second gears 92 are meshed and connected. The second servo motor 91 is mounted on the mounting bracket 23 and its output shaft is connected to the left winding roller 61. The right side of the processing box 3 is equipped with a second drive assembly for driving the two right winding rollers 62 to rotate synchronously. The second drive assembly includes a first servo motor 81 and two first gears 82. The two second gears 92 are respectively mounted on the ends of the two left winding rollers 61. The two second gears 92 are meshed and connected. A gear 82 is respectively installed on the end of the two right winding rollers 62, and the two first gears 82 are meshed and connected. The first servo motor 81 is installed on the mounting bracket 23 and its output shaft is connected to the right winding roller 62. Long felts 7 are fixedly wound around the two left winding rollers 61. The other ends of the two long felts 7 pass through the right through-hole 301 and the left through-hole 302 and are respectively fixed on the two right winding rollers 62. A fixed plate and a pressure plate can be installed on the inner side of the processing box 3. The fixed plate is fixedly connected to the inner wall of the processing box 3. The pressure plate is slidably arranged on the inner side of the processing box 3. The pressure plate is located above the fixed plate, and the two long felts 7 are located between the pressure plate and the fixed plate. This structure is set up to squeeze the two long felts 7 with a certain pressure while ensuring the smooth movement of the copper wire to avoid a large gap between the two long felts 7.

[0026] The infusion device is used to transport the antioxidant to the inside of the treatment box 3. The infusion device includes a dripping bottle 2, a dripping tube 10, a flow control valve 11, a liquid collecting tank 14 and a liquid guide plate 16. The dripping bottle 2 is arranged above the treatment box 3, the dripping bottle 2 is installed on the annealing furnace 1, the dripping tube 10 is connected to the bottom end of the dripping bottle 2, the bottom end of the dripping tube 10 is arranged on the inside of the treatment box 3, the flow control valve 11 is installed on the dripping tube 10, and the dripping tube 10 is arranged to control the antioxidant. The output flow rate of the oxidant, the collecting tank 14 is installed on the inner side of the processing box 3, the liquid guide plate 16 is connected to the bottom end of the collecting tank 14, and a strip hole 141 is opened on the collecting tank 14. The antioxidant output through the drip bottle 2 flows into the inner side of the collecting tank 14, and then overflows through the collecting tank 14, so that the antioxidant flows through the side wall of the liquid guide plate 16 to the surface of the long-haired felt 7. Through the arrangement of the above structure, the antioxidant can flow evenly to the surface of the long-haired felt 7.

[0027] The two high-pressure nozzles 15 are both mounted on the mounting bracket 23 and are respectively used to clean the two long-haired felts 7 . A wastewater collection box 5 can be provided below the high-pressure nozzles 15 for collecting wastewater.

[0028] A recovery box 4 is provided below the treatment box 3, and a recovery pipe 12 is provided between the recovery box 4 and the treatment box 3. A filter can be installed on the recovery pipe 12 to filter impurities in the recovered antioxidant. A one-way valve 13 is installed on the recovery pipe 12, and the excess antioxidant can be recovered through the recovery box 4.

[0029] In this embodiment, an antioxidant is delivered to the inside of the treatment box 3 through an infusion device. The antioxidant is alcohol or physiological saline. The antioxidant drips onto the long-haired felt 7, so that the long-haired felt 7 is soaked. The copper wire removed from the annealing furnace 1 is moved through the annealing furnace 1. Through holes are opened at both ends of the annealing furnace 1 for the copper wire to pass through, and the copper wire is placed between two long-haired felts 7. At this time, the copper wire is anti-oxidized and cleaned, and the copper wire can also be cooled. In the process of anti-oxidation treatment of the copper wire, a certain amount of metal debris will remain on the surface of the long-haired felt 7. If these metal debris accumulate too much, it will cause surface wear of the copper wire. During cleaning, the two long-haired felts 7 are unwound synchronously by the first driving component, and then the two long-haired felts 7 are rewound synchronously by the second driving component, so that the contaminated parts of the two long-haired felts 7 are simultaneously moved out from the inner side of the treatment box 3, and then the two high-pressure nozzles 15 are connected to the water pipe of the water pump, and the two high-pressure nozzles 15 spray water to the contaminated parts of the two long-haired felts 7 respectively, so as to clean the dirt on the surface of the long-haired felts 7. At this time, the uncontaminated areas on the two long-haired felts 7 are moved to the position of the copper wire. Before this, the output flow rate of the antioxidant should be increased so that the long-haired felts 7 can be quickly soaked.

[0030] Example 2

[0031] like Figure 3 and Figure 4As shown, the present embodiment proposes a copper wire drawing annealing device for cable production. Compared with the first embodiment, in the present embodiment, two V-shaped pressure plates 17 are symmetrically arranged on the upper and lower sides of the inner side of the right through-hole 301, and the two V-shaped pressure plates 17 are connected with vertical plates 18. The two vertical plates 18 are movable through the upper and lower ends of the processing box 3 respectively, and the outer ends of the two vertical plates 18 are connected with movable plates 19. Elastic components are connected between the processing box 3 and the two movable plates 19, and the elastic components include a guide rod 20, a spring 21 and a limit block 22, wherein the guide rod 20 is connected to the outer wall of the processing box 3, the movable plate 19 is slidably set on the guide rod 20, and the spring 21 is sleeved and installed on the guide rod 20. The positioning block 22 is arranged at the end of the guide rod 20; when the long-haired felt 7 is driven to move, the two long-haired felts 7 are squeezed by the two V-shaped pressure plates 17, so that the excess antioxidant on the long-haired felt 7 can be squeezed out and flow into the inner side of the processing box 3 through the inclined surface of the bottom V-shaped pressure plate 17. When the left winding roller 61 is almost completely unwound, the left winding roller 61 is driven to rotate in the opposite direction by the first driving component. At this time, the left winding roller 61 rewinds the long-haired felt 7, and the clean moisture on the long-haired felt 7 flows to the outside of the processing box 3 through squeezing. In addition, the above-mentioned structure can also reduce the exposed gap of the right perforation 301 to prevent a large amount of antioxidant from volatilizing into the outside air.

[0032] The embodiments of the present invention are described in detail above with reference to the accompanying drawings, but the present invention is not limited thereto. Various changes can be made within the knowledge scope of those skilled in the art without departing from the purpose of the present invention.
