The Influences of the Die-Exit Upon the Properties of Drawn Wires*

Hiroshi Tanaka** and Makoto Sato**

If the drawing direction of the wire is not aligned with the axis of the die-hole, the wire has to be continuously bent over the die-exit. The authors' intention was to find out what influences the deflection (the angle α between the die-axis and the drawing direction) had on the properties of the wires drawn as described above. Copper and aluminium wires were used. It was determined that if α was more than 5°, hard copper wire decreased in strength, while aluminium wire became stronger. In all cases, the free looping diameter (the diameter of the wire-loop which results after the wire was drawn and thrown on the floor) sharply decreases if α was increased more than 5°, causing the wire to pile up very tightly on to the take-up drum.
