Abstract
The present invention discloses a fine composite conducting wire and a production method thereof. The fine composite conducting wire is formed by the composition of a core body and a coating layer, and the diameter of the fine composite conducting wire is from 0.025 to 1.0mm. The production method comprises the following steps: copper is coated on a steel wire or an aluminum rod of which the diameter is from 6 to 10mm to be made into composite blank; the speed of 100 to 150 m/min and the diameter-reducing rate of 13 to 18% are used for carrying out drawing to the composite blank, and the diameter of the composite blank becomes 1.5mm through drawing; the drawing speed adjusted to be 1500 to 2500 m/min and the diameter-reducing rate adjusted to be 3 to 12% are used for carrying out the drawing, and the diameter of the composite blank becomes 0.025 to 1.0mm. The present invention overcomes the prejudices of the prior art; when the diameter of the composite conducting wire reaches 1.5mm, the diameter-reducing rate is lowered, but the drawing speed is increased by more than ten times; the fine composite conducting wire of which the diameter is 0.025 to 1.0mm can be produced; the existing pure copper enamel wire and copper-plating fine wire are replaced; the present invention solves the past technical problems of high product price, environment pollution, etc., and the requirements of people for a fine copper-coating aluminum enamel wire or a fine copper-coating steel wire are satisfied.
Description
Technical field:
The present invention relates to a kind of compound wire, fine composite conducting wire and production method that especially a kind of diameter is 0.025～1.0mm.
Background technology:
At present; about copper cover aluminum; copper covered steel; the patent of compound wires such as stainless steel Baogang is existing a lot; but its production method all is the Chinese invention patent application number basically is 98112410.0; name is called " a kind of compound copper-aluminium wire and production technology " disclosed method; promptly " after copper strips (or copper pipe) after will fully annealing with wire wheel and aluminium bar surface passivation layer remove; employing cladding method wraps into copper strips with aluminium bar; and copper strips curved tubulose; seam under protective atmosphere; or with tiretube process aluminium bar is packed in the copper pipe; composite blank made; again with stretching; extruding or prick the way of (rolling) system, the composite blank machining deformation that cladding method or tiretube process are made is until final size ".Extruding or milling method adopt hot working, and its technology is cumbersome, and every distortion once all needs intermediate annealing; What be that drawing adopts is cold working and stretch, and needs to determine correct drawing speed and deformation rate (reducing rate) composite blank to be machined to final size.No matter be hot working or cold working, its final diameter of compound wire that existing method is processed is 1.5mm～5.5mm (above-mentioned patent application embodiment is 4.096mm) basically, can not satisfy the requirement of fine copper-in-aluminum enameled wire or fine copper covered steel wire, so existing enamelled wire is the higher pure copper wire of price in the past still, building and fine copper wire peculiar to vessel then are copper facing on the common metal silk, not only price height, and the waste liquor contamination environment that is discharged.With the immediate technology of the production method of present patent application be the cold working drawing process, present drawing process is that the maintenance drawing speed is 100～150m/min, reducing rate is 10%～20%, if when the diameter of compound wire reaches 1.5mm, also carry out drawing with this speed and reducing rate, the phenomenon of compound wire fracture then can take place, so the final diameter of compound wire can only be more than the 1.5mm at present.
Summary of the invention:
The present invention is in order to solve the technical problem that existing in prior technology can not satisfy fine copper-in-aluminum enameled wire or fine copper covered steel wire requirement, a kind of fine composite conducting wire and production method to be provided.
Technical solution of the present invention is: a kind of fine composite conducting wire, be composited by core body and coating layer, and core body is aluminium or steel, external coating is a copper, it is characterized in that: its external diameter is 0.025～1.0mm.
A kind of production method of fine composite conducting wire, its step is as follows:
A. be on the steel wire or aluminium bar of 6～10mm, to make composite blank at diameter with copper clad;
B. carry out the drawing composite blank with the speed of 100～150m/min, 13～18% reducing rate, being drawn to diameter is 1.5mm;
C. adjusting drawing speed is 1500～2500m/min, and reducing rate is 3～12% to carry out drawing, and being drawn to diameter is 0.025～1.0mm.
The present invention has overcome existing technology prejudice, when the compound wire diameter reaches 1.5mm, reduce reducing rate and but increase drawing speed, its drawing speed increases more than 10 times, can produce diameter is fine copper cover aluminum or the copper covered steel compound wire of 0.025～1.0mm, substitute existing fine copper enamelled wire and copper-plated glass-coated microwire, solved technical problems such as product price height, environmental pollution in the past, satisfy the requirement of people fine copper-in-aluminum enameled wire or fine copper covered steel wire.
