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
[0015] specific implementation plan
[0016] As can be seen from the accompanying drawings, a copper-plated nickel-plated alloy wire production process, its production process is as follows:
[0017] A. Surface treatment: use 4J43 alloy wire with a diameter of 2.3 mm to draw through the water tank wire drawing machine 1 to a diameter of 1.5 mm, and then keep it in the pit furnace 2 at a temperature of 900 ° C for 2 hours for annealing, and finally place 18% sulfuric acid liquid Carry out pickling for 3 minutes in the pickling tank 3;
[0018] B. Carry out electroplating: After the above-mentioned surface-treated alloy wire is put on the car 4, it is pickled in the pickling tank 3 of 18% sulfuric acid liquid for 1 minute, cleaned in the tap water tank 5 for 0.5 minutes, and then in the 18% nickel sulfate tank Nickel plating in 6 liters for 1 minute, then cleaning in tap water tank 5 for 0.5 minutes, and finally copper plating in 28% electrolytic copper tank 7 at a temperature ...

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 for a copper-plated nickel-plated alloy wire used in white dumet wire materials in electric bulbs. Background technique [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. Contents of the invention [0003] In view of the ab...
