Abstract
Description
Technical Field
[0001] This utility model belongs to the field of wire and cable processing technology, and in particular relates to a large copper wire drawing machine suitable for wire and cable processing. Background Technology
[0002] Wire and cable processing involves stranding, extruding, and cabling metal conductors with insulation and sheathing materials to transform raw materials into cable products with specific electrical and mechanical properties. This covers the manufacturing of cables for power transmission, communication signals, and special purposes. Precision processing ensures that the products meet voltage levels, environmental adaptability, and safety standards, and are ultimately used in key fields such as energy, construction, transportation, and communications. During the wire and cable processing, a copper wire drawing machine is used to draw the conductors to ensure that their specifications meet processing requirements.
[0003] Existing copper wire drawing machines require recrystallization heat treatment of the copper wire through annealing after the copper wire is drawn. During the annealing process, the copper wire is heated. At this time, the high-temperature copper wire is exposed to air during transmission, especially when it comes into contact with oxygen-containing air before winding. Its surface will quickly oxidize and form a black layer of copper oxide. Although the traditional process of using emulsion cooling can reduce the wire temperature, the residual liquid film on the surface of the high-temperature copper wire will produce vapor corrosion, which will aggravate the oxidation phenomenon and is not conducive to use.
[0004] To address these issues, we provide a copper wire drawing machine suitable for wire and cable processing. Utility Model Content
[0005] The purpose of this utility model is to provide a copper wire drawing machine suitable for wire and cable processing. By combining the sealing cooling component and the sealing winding component, it solves the problem that the existing copper wire drawing machines for wire and cable processing do not have sealing cooling and sealing winding functions, and the copper wire is easily exposed to air after annealing, which leads to oxidation and blackening of the copper wire surface and affects the quality of the copper wire.
[0006] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution.

The electric cylinder can adjust the working height of the friction plate.
[0009] The present invention is further configured such that a gas tank is fixedly connected to the rear side of the right side of the large pulling machine body, the gas outlet at the top of the gas tank extends into the inner cavity of the cooling shell, the friction plate is L-shaped, the gas tank is used to store nitrogen and continuously replenish nitrogen to the inside of the cooling shell, and the L-shaped friction plate facilitates the connection of the electric cylinder to it.

[0015] The present invention has the following beneficial effects.
[0016] 1. This utility model utilizes a sealed cooling component, employing a cooling shell and guide wheel to extend the cooling path of the copper wire in a sealed nitrogen environment. Combined with a multi-angle exhaust mechanism that circulates and blows low-temperature nitrogen gas, the heat on the copper wire surface is quickly and evenly removed. Simultaneously, the cooling mechanism continuously cools the nitrogen gas, ensuring the cooling medium remains at a low temperature. This effectively avoids the vapor corrosion problem caused by residual emulsions in traditional systems. By continuously replenishing nitrogen into the sealed space through a gas tank, oxygen is prevented from contacting the high-temperature copper wire, thus preventing the formation of a black layer of copper oxide at the source. This solves the problem of secondary corrosion caused by oxidation of the copper wire after annealing and deterioration of the cooling medium, significantly improving the surface quality of the copper wire.
[0017] 2. This utility model uses a sealed winding assembly to construct a closed winding chamber with a sealed shell. In conjunction with an electric push rod and a winding roller, it achieves full nitrogen protection during the copper wire winding process. The motor drives the rotating roller to rotate the winding roller at a uniform speed, ensuring that the copper wire is wound in an oxygen-free environment. This avoids surface oxidation caused by air intrusion during the winding stage. The sealing door and sealing gasket further enhance the airtightness of the chamber. Combined with the controller, the nitrogen concentration and ambient temperature are precisely controlled to form a closed loop of anti-oxidation from cooling to winding. This completely eliminates the defect of copper wire terminal oxidation and blackening in traditional processes, ensuring the conductivity and mechanical strength of the finished cable.

The hot end of the bottom of the cooler 452 passes through the cooling housing 451 and is fixedly connected to the heat dissipation fins. The top and bottom of the inner cavity of the cooling housing 451 are fixedly connected to the air guide plate 455.

The front and rear sides of the guide wheel 42 are movably connected to the inner wall of the cooling housing 41 through bearings.
[0031] Specifically: the exhaust hood 441 can discharge nitrogen gas, allowing it to quickly wash the surface of the copper wire; the friction wheel 442 can cooperate with the friction plate 444 to control the exhaust hood 441 to continuously swing up and down, improving its cooling effect; the electric cylinder 443 can adjust the working height of the friction plate 444; the gas tank 445 is used to store nitrogen gas and continuously replenish nitrogen gas inside the cooling shell 41; the L-shaped friction plate 444 facilitates the connection of the electric cylinder 443 to it; the cooling shell 451 can cool the nitrogen gas inside the cooling shell 41; the cold end of the cooler 452 is used to lower the temperature, making the nitrogen gas temperature lower; the fan 453 and the hose 454 deliver the cooled nitrogen gas back to the exhaust hood 441.

[0032] The working principle of this utility model is as follows: After the copper wire is drawn and annealed by the large drawing machine body 2, it enters the cooling shell 41 through the outlet pipe. The guide wheel 42 guides the copper wire into a multi-segment reversal path, extending its residence time in the sealed nitrogen environment. The gas tank 445 continuously replenishes nitrogen into the cooling shell 41 to form a positive pressure environment, isolating external oxygen. The cooler 452 continuously cools the circulating nitrogen through the cooling shell 451. The fan 453 delivers the low-temperature nitrogen to the exhaust hood 441 through the hose 454. In the multi-angle exhaust mechanism 44, the electric cylinder 443 periodically adjusts the contact position between the friction plate 444 and the friction wheel 442, driving the exhaust hood 441 to reciprocate. The exhaust hood 441 sprays low-temperature nitrogen gas onto the surface of the copper wire from different angles to achieve three-dimensional scouring heat exchange. The heated nitrogen gas flows back to the cooling shell 451 through the bottom of the cooling shell 41. Under the guidance of the air guide plate 455, it passes evenly through the cold end of the cooler 452. After completing the heat exchange, it re-enters the circulation. The cooled copper wire enters the sealed shell 3. The controller monitors and adjusts the nitrogen concentration in the cavity in real time. The motor 53 drives the rotating roller 54 to drive the winding roller 51 to rotate at a uniform speed, so that it can wind the copper wire. The sealing door and the sealing gasket work together to maintain the airtightness of the winding chamber, ensuring that the copper wire is in an oxygen-free environment throughout the entire process from cooling to winding, blocking the oxidation reaction and preventing the copper wire from oxidizing and turning black, which would affect the quality.
