Abstract
PURPOSE: To manufacture the aluminum covered copper wire with small thickness deviation, by cylindrically covering the copper wire with the aluminum tape, traveling along the copper made core wire, using the forming dies, and then, by welding the seam portion of the aluminum tape, and by carrying out the cold wire drawing through the dies of narrow dies angle.
CONSTITUTION: The copper made core wire C is fed from the feeder 1 to the straightener 2 where the core wire C is strainghtened; after that, the core wire C is cleaned by the surface treating device 3, and is sent to the forming roll 4. In the mean time, the aluminum made tape (a) is sent from the feeder 8 to the surface treating device 9, where the tape is cleaned; after that, the tape is laid parallelly to the core wire C. Next, the tape (a) is rolled and formed into cylinder type covering the core wire C by the forming roll 4 and the forming dies 5. Then, the seam portion of this cylindrical tape (a) is welded 6, and the cylindrical tape (a) is coiled. Thus obtained composite bus bar is processed by cold wire drawing at 70% or more drawing rate uring the narrow angle dies whose halved dies angle is 3W10 degrees. Hereby, the aluminum covered copper wire with small thickness deviation can be manufactured
