Problems solved by technology

[0004] In the actual production process of the above-mentioned production process, the change of temperature to the conductor should be considered. If the temperature is too high, it will easily separate copper and aluminum, and if the temperature is too low, it will not be able to meet the due characteristic requirements. temperature for production

Embodiment 1

[0053] Embodiment one: a kind of production technology of 200 grade copper-clad aluminum magnet wires, such as figure 1 As shown, the prepared aluminum wire and copper strip are firstly washed with alkali to wash off most of the impurities and oxide film on the surface of the aluminum wire and copper strip. , the remaining impurities that are difficult to remove should be sanded off with sandpaper to ensure that there are no impurities on the surface of the copper strip and aluminum wire.

[0054] Such as figure 1 As shown, the copper strip is wrapped on the aluminum wire, and a special wire drawing die is used for wire drawing to obtain a preliminary formed copper-clad aluminum bare wire. The wire drawing die can use the copper-clad aluminum wire drawing machine produced by Mitutoyo Electromechanical Development Co., Ltd.

[0055] Such as figure 1 As shown, the copper-clad aluminum wire with a diameter of 2.05mm was annealed, and the annealing time was 25min, and the annea...

Embodiment 2

[0067] Embodiment 2: The difference from Embodiment 1 lies in that the annealing temperature is 350° C. and the annealing time is 25 min, 30 min and 35 min respectively during the annealing process.

[0068] Embodiment two prepares the performance test data of copper-clad aluminum bare wire, as shown in table 3:

[0069] table 3

[0070]

[0071] According to Table 3, the best annealing time for copper-clad aluminum bare wire with a diameter of 2.05mm is 30min.

Embodiment 3

[0072] Example 3: The difference from Example 1 is that a copper-clad aluminum bare wire with a diameter of 1.06mm is selected, the annealing time is 60min, and the annealing temperatures are 250°C, 300°C, 310°C, 400°C and 450°C respectively Test separately.

[0073] Embodiment three prepares the performance test data of copper-clad aluminum bare wire, as shown in table 4:

[0074] Table 4

[0075]

[0076] According to Table 3, the optimal temperature for annealing copper-clad aluminum bare wire with a diameter of 1.06mm is 310°C.

Abstract

The invention discloses a production process of a class 200 copper-clad aluminum electromagnetic wire, belonging to the field of copper-clad aluminum electromagnetic wires, and the technical proposalthereof comprises the following steps of: cleaning the surfaces of the aluminum wire and the copper strip to remove impurities and an oxide layer; coating the copper strip on the aluminum wire and then drawing by using a special wire drawing die; annealing the copper-clad aluminum bare wire, maintaining the annealing temperature at 300 to 400 degrees centigrade; painting the copper-clad aluminum bare wire to ensure uniform painting, placing the painted copper-clad aluminum bare wire in the film curing oven for baking, and maintaining the baking temperature at 450 to 500 degrees centigrade; lubricating the surface of the formed copper-clad aluminum electromagnetic wire to make the surface of the copper-clad aluminum electromagnetic wire smooth and uniform in thickness; and winding up the final copper-clad aluminum magnet wire, thereby solving the problem that it is difficult to select a suitable temperature in the production process of the copper-clad aluminum magnet wire, and improvingthe quality of the copper-clad aluminum magnet wire, so that the connection between copper and aluminum is tight and the toughness is good.

Description

technical field [0001] The invention relates to the field of copper-clad aluminum magnet wires, in particular to a production process of 200-grade copper-clad aluminum magnet wires. Background technique [0002] Copper-clad aluminum magnet wire is a new type of magnet wire that uses copper-clad aluminum material as the inner conductor. Its characteristics are between copper and aluminum, combining the excellent electrical conductivity of copper and the light weight of aluminum. The DC resistivity of copper-clad aluminum wire is about 1.45 times that of pure copper wire; when the resistance value is the same, the weight of copper-clad aluminum wire is about 1 / 2 of pure copper wire. Copper-clad aluminum wire is concentrically coated with a layer of pure copper, so it has the same brazing properties as pure copper wire, without special treatment like aluminum wire; at the same time, copper-clad aluminum wire has a thicker The copper layer ensures that the soldering performanc...
