Abstract
The invention discloses a method for lacquering large-sized enamelled CCA (copper clad aluminum) wires. The method comprises the following steps: pulling out CCA wires subjected to drawing; sequentially carrying out annealing, lacquering, baking and cooling treatment on the CCA wires; and winding up the CCA wires, wherein in the step of pulling out CCA wires, two coils of CCA wires which are continuously operated are connected to be a continuous wire by using a connecting process, and the step of pulling out CCA wires is characterized in that the connecting process is implemented by using a hydraulic connecting device. By using the method disclosed by the invention, the problem of difficult connection existing in the processes of pulling out and lacquering CCA wires can be solved effectively.
Description
Technical field
The present invention relates to lackering method, specially refer to the lackering method of large size copper alclad line.
Background technology
Enamelled wire is a principal item of winding wire, is made up of conductor and two ones of insulating barriers, and bare wire forms through repeatedly painting, curing behind annealing softening again.But producing is the conformance with standard requirement, satisfy the product of customer requirement again and be not easy, it is subjected to raw material quality, technological parameter, production equipment, factor affecting such as environment, therefore, the mass property of various enamelled wires has nothing in common with each other, but all possesses mechanical performance, chemical property, electrical property, hot property four big performances.
Copper-in-aluminum enameled wire is comparatively use always in the enamelled wire a kind of.Copper-in-aluminum enameled wire is to adopt copper clad aluminum material to make the electromagnet line of inner wire, and its characteristic combines the good electric conductivity of copper and the lightweight advantage of aluminium between copper aluminium.
The present extensive use of copper-in-aluminum enameled wire field is in high frequency transformer, common transformer, inductance, and solenoid, motor comprise the higher fields such as motor of environmental requirement such as family expenses motor, various micromachine and compressor.But because the narrow-mindedness of himself can not be adopted by high-power transformer usually.
The copper-in-aluminum enameled wire of big specification is applicable to high-power transformer, but large size copper alclad enamelled wire radius is thicker, and resistivity is less, and in the lacquer process, because radius is thicker, joint is difficult to control thereon, is easy to produce broken string.
Summary of the invention
At the problems referred to above, main purpose of the present invention provides a kind of lackering method of large size copper alclad enamelled wire, can be convenient to continuous operation and be carried out the joint operation by two rosette copper alclad lines.
In order to solve an above-mentioned difficult problem, the scheme that the present invention takes is: the lackering method of large size copper alclad enamelled wire, comprise the copper-clad aluminum conductor that involves after the drawing, do successively then to anneal, paint, cure, cooling processing, until take-up, in involving the step of copper-clad aluminum conductor, continuously operated two rosette copper alclad lines join into continuous line through joint technology, and joint technology is finished by the operation of hydraulic joint device.
Further, the step that involves copper-clad aluminum conductor adopts traction drive to finish automatically.
Further, the temperature of annealing is 450-480 degree centigrade.
Further, the japanning step comprises that being coated with thickness earlier is 0.02mm heat-resistant polyester material, and being coated with thickness again is the 0.10mm polyester imines.
Further, the japanning step adopts the mold painting mode, and mold painting is finished by the instrument that comprises lacquer case, lacquer pump and the groove consistent with the copper-clad aluminum conductor shape.
Further, mold painting comprises and is coated with the hot polymerization ester material earlier one, is coated with nine road polyester imines again.
Further, the japanning step adopts felt japanning mode, and the felt japanning is finished by the instrument that comprises lacquer stove, felt paint roller.
Further, baking step adopts baker to carry out, and the inlet temperature of baker is 190-210 degree centigrade, and the baker central temperature is 310-330 degree centigrade, and the baker outlet temperature is 450-470 degree centigrade.
Further, the temperature that cooling is adopted to copper-clad aluminum conductor is 40-60 degree centigrade.
The present invention adopts above method, has solved the problem of copper-in-aluminum enameled wire japanning distraction step center tap difficulty.
