Problems solved by technology
[0002] At present, the Dumet wire used for lapping tungsten wires in electric light bulbs on the market is made by magnesium-plating production process. The light emitted by the tungsten wire is affected by the radiation of the dark red Dumet wire, and the light is slightly reddish, which affects the light for people to read books and newspapers; in addition, the quality of the magnesium plating production process is not very stable, sometimes causing extremely difficult to appear on the surface of the Dumet wire. The small gaps found, after electrification, the small gaps will generate bubbles under the action of vacuum and high temperature in the bulb, so that the bulb will not light up

Embodiment Construction
[0014] specific implementation
[0015] As can be seen from the accompanying drawings, a kind of copper-plated nickel-plated alloy wire production technology, its production technology process is as follows:
[0016] A. Surface treatment: 4J43 alloy wire with a diameter of 2.3 mm is drawn through a water tank wire drawing machine to a diameter of 1.5 mm, and then annealed in a pit furnace with a temperature of 900 ° C for 2 hours, and finally placed in 18% sulfuric acid liquid acid Pickling in the washing tank for 3 minutes;
[0017] B. Electroplating: After the above-mentioned surface-treated alloy wire is put on the car, pickled in a pickling tank of 18% sulfuric acid for 1 minute, cleaned in a tap water tank for 0.5 minutes, and then plated with nickel in a 18% nickel sulfate tank 1 minute, then cleaned in the tap water tank for 0.5 minutes, and finally copper-plated in the electrolytic copper tank 7 with a temperature of 30°-40°C and a content of 28% for 2 hours, and the ...

The invention discloses a good-quality and -effect copper- and nickel- plated alloy wire producing technique, including the courses: surface processing, plating, surface reprocessing, replating, producing the finished products, etc; wiredrawing repeatedly can make the diameter of alloy wire stretched / shrunk up to the needed specification; plating copper and nickel many times can make copper and nickel completely cover the outer surface of the alloy wire; tube annealing can make original alloy wire without stretching force able to generate the stretching force by 20% above; it solves the defects in that the dume wire produced by traditional Mg plating technique has red light in the bulb and the surface of the dume wire sometimes has fine gap so as to be easy to bubble, and is a new material replacing the dume wire.
Description
technical field [0001] The invention relates to an electroplating process, in particular to a production process of a copper-plated nickel-plated alloy wire used as a white Dumet wire material in an electric light bulb. Background technique [0002] At present, the Dumet wire used to lap tungsten filaments in the light bulbs on the market is produced by the magnesium plating production process. The light emitted by the tungsten wire is affected by the radiation of the dark red Dumet wire, and the light is slightly reddish, which affects the light of people reading books and newspapers; in addition, the quality of the magnesium plating production process is not very stable, and sometimes the surface of the Dumet wire is extremely difficult to appear. The found fine gap, after the power is turned on, the fine gap produces bubbles under the action of vacuum and high temperature in the bulb, so that the bulb does not light up. SUMMARY OF THE INVENTION [0003] Aiming at the a...
