Embodiment Construction

[0020] The invention discloses a copper-clad aluminum enameled wire processing technology, which comprises the following steps:

[0021] (a) Multiple drawing of the copper-clad aluminum wire core;

[0022] (b) Apply multiple coats of paint to the drawn wire core, and each coat of paint includes the following steps:

[0023] (b1) paint the wire core,

[0024] (b2) putting the painted wire core into an oven for multi-pass drying;

[0025] (c) take-up;

[0026] (d) Dismount and pack.

[0027] In the above steps, since the wire core has been dried for multiple times, it has met the requirements of stress removal, that is to say, it is not necessary to go through the process of annealing, thereby eliminating the device of annealing furnace, which is very important for factories and enterprises. The production cost is greatly saved, and since the required temperature of the annealing furnace is relatively high, it also contributes to energy saving and environment...

Abstract

The invention discloses a processing technology of copper-clad aluminum varnished wires. The processing technology of the copper-clad aluminum varnished wires comprises the following steps that (a) the copper-clad aluminium wire cores are drawn for a plurality of times; (b) a plurality of japannings are conducted to the drawn conductor wire cores. Each japanning comprises the following steps (b1) the wire cores are japanned, (b2) the japanned wire cores are placed into a baking oven and a plurality of dryings are conducted to the wire cores; (c) the wire cores are rewinded; (d) the wire cores are coiled and packaged. Four to six drawings are conducted to the copper-clad aluminum varnished wire cores. Ten to twelve japannings are conducted to the drawn the wire cores. In each japanning step, six to ten dryings are conducted to the japanned varnished wires. The speed of collected wire cores is (5 + / - 1) miles / minute. In the steps, due to the fact that a plurality of dryings are conducted to the wire cores so that the wire cores achieve the requirements of eliminating stress. Thus, the wire cores do not need to undergo an annealing process so that an annealing furnace is saved. Accordingly, production cost of a factory or an enterprise can be saved.

Description

technical field [0001] The invention relates to a copper-clad aluminum enameled wire processing technology. Background technique [0002] The traditional copper-clad aluminum enameled wire processing technology is as described in CN101325102, and generally adopts the following steps: (1) wire drawing; (2) wire drawing; (3) cleaning; (4) annealing; (5) cooling; (6) painting , baking, and cooling. In ZL 201010548226.7, another enameled wire processing technology is described, which includes the following steps: (a) drawing the copper-clad aluminum wire core 4 to 6 times; (b) drawing the wire after drawing 10 to 13 coats of paint are applied to the core, and each coat of paint includes the following steps: (b1) paint the wire core, (b2) put the painted wire core into an annealing furnace for annealing, (b3) anneal the wire core after annealing The core of the wire is put into the oven for drying; (c) take-up. It can be seen that annealing is an essential step in the tradition...
