Description

Technical Field

[0001] The utility model relates to an anti-oxidation device for toughened copper conductors for electric wires and cables, which is a device used for applying an antioxidant during the twisting process of electric wires and cable conductors, and belongs to the technical field of processing metal conductors of electric wires and cables. Background Art

[0002] With the faster and faster development of emerging fields such as aerospace, robotics, wind power, and new energy vehicles, higher and higher requirements are placed on wires and cables, especially wrapped wires. As a commonly used cable conductor, oxygen-free copper is easily oxidized during processing, storage, and use in rainy seasons and humid environments. The oxidation and blackening of the wire surface will not only seriously affect its appearance and surface quality, but also have a serious adverse effect on its signal transmission performance, thereby reducing its electrical properties and causing a lot of waste. This problem can be solved by adding oxidants. At present, manufacturers generally add antioxidants to the cooling water during the annealing process. However, the temperature of the copper wire is high after leaving the annealing tube, and steam is formed instantly when it comes into contact with the cooling water, resulting in the inability to apply the antioxidant evenly. Local oxidation forms black spots. In response to this situation, it is necessary to develop a device for applying antioxidants during the stranding process. Summary of the invention

[0003] In view of the deficiencies in the prior art, the utility model provides an anti-oxidation device for tough copper conductors for wires and cables, which effectively reduces the oxidation probability of tough copper wires, extends the shelf life of tough copper wires, and at the same time avoids oxidation of wrapped wire cables during the sintering process, reducing waste.

[0004] The technical solution adopted by the utility model is: an antioxidant device for tough copper conductors for wires and cables, a wire passing mold is fixed on one side of the coating device, a wire passing porcelain nozzle is fixed on the other side, a plurality of liquid adding devices and a transparent observation window are provided on it, the pressure plate is arranged in the coating device, a plurality of pressure springs are arranged between the pressure plate and the other side of the coating device, the wire passing mold holes of the wire passing mold, the wire passing holes of the pressure plate and the wire passing porcelain nozzle are arranged correspondingly, the filling cotton is arranged in the coating device, and the filling cotton contains antioxidants.

[0005] The utility model has the beneficial effects that, compared with adding antioxidants by directly applying or applying on a wire wiping cloth, the utility model applies the antioxidant more evenly and reduces the uncertainty of manual addition. At the same time, after adding, it is scraped off through a mold to avoid the antioxidant from entering the wire-taking device, making the conductor surface even and clean.

[0010] A tough copper conductor anti-oxidation device for electric wires and cables comprises a coating device 1, a wire passing die 2, a wire passing porcelain nozzle 3, a liquid adding device 4, a transparent observation window 5, a filling cotton 6, a pressure plate 7, and a pressure spring 8.

[0011] The coating device 1 is a circular cylinder structure, with a wire mold interface 1-1 on one side of the coating device 1, a wire porcelain nozzle hole 1-2 on the other side of the coating device 1, and multiple liquid adding device interfaces 1-2 and a transparent observation window 5 on the upper side of the coating device 1.

[0012] The pressure plate 7 is circular, with a wire hole 7-1 at the center of the pressure plate 7; the wire die 2 is circular, with a wire die hole 2-1 at the center of the wire die 2, and the wire die hole 2-1 is composed of two trumpet-shaped small-diameter end holes connected together.

[0013] A pressure plate 7 is arranged in the coating device 1, and a plurality of pressure springs 8 are arranged between the pressure plate 7 and the other side of the coating device 1. The coating device 1 between the pressure plate 7 and the wire-passing mold interface 1-1 is filled with filling cotton 6. The wire-passing mold 2 and the wire-passing mold interface 1-1 of the coating device 1 are fixed together, and the wire-passing porcelain nozzle 3 is installed on the wire-passing porcelain nozzle hole 1-2. The wire-passing mold hole 2-1, the wire-passing hole 7-1 and the wire-passing porcelain nozzle 3 are correspondingly arranged on an axis. At least two liquid-adding device interfaces 1-2 are respectively connected to a liquid-adding device 4 through a hose, and antioxidants are injected into the filling cotton 6 in the coating device 1 through the liquid-adding device 4, and the antioxidants fill the filling cotton 6.

[0014] There are at least two liquid adding devices 4, which are composed of a liquid storage container, a hose, and a timing solenoid valve. The liquid storage container is a well-known container, and the timing solenoid valve model is the AC220V4 split electronic drain valve of Delixi Pneumatic. The timing solenoid valve is connected to the liquid storage container through a hose, and the timing opening and closing achieves the purpose of liquid adding.

[0015] Method of use: one end of the cable conductor is connected to the wire taking-up device through the wire porcelain nozzle 3, the wire hole 7-1, the filling cotton 6 with antioxidant and the wire die hole 2-1 in sequence, so that the cable conductor is coated with antioxidant inside the coating device 1.

[0016] In order to ensure that the cable conductor passes through the coating device and remains loose for easy coating, a wire-passing porcelain nozzle 3 is used to avoid damage to the cable conductor; in order to evenly coat the surface of the cable conductor with antioxidant, filling cotton 6 with antioxidant is used; in order to keep the filling cotton 6 in a saturated state and prevent the antioxidant liquid from overflowing, a pressure plate 7, filling cotton 6 and pressure spring 8 are used in combination to squeeze the filling cotton in the coating device, so that the cable conductor can be coated with the oxidizing liquid more evenly and stably.

[0017] In order to ensure that the antioxidant inside the coating device 1 is sufficient, a liquid adding device 4 is used to add antioxidants to the cylinder body through a connecting hose at regular intervals during the equipment operation procedure to ensure the antioxidant concentration;
