Continuous drawing of copper wire - uses coils whose ends are joined by welding prior to feeding in

摘要

To speed up the drawing operation of copper conductors, coils of semi-drawn wires are linked by welding their ends together. The coils are then placed in such a way that when one coil is finished, the beginning of the next coil is automatically pulled through the draw die. This enables the draw process to be continuous, thus producing wires of any length required. The unit is partic. for wire or rod of between 8-14mm requiring a reduction in dia. of 20-35%. The feed roll is carried on a horizontal axis, and the roll of the drawing appts. runs on a vertical axis.
