Three common problems in copper wire drawing

1. Unstable tension on the wire storage wheel

The use of air pressure in the production workshop may be more, which will cause the air pressure of the wire drawing machine pump is large or small, which makes the tension of the wire storage device is not constant, and because the speed of the wire is constant, it makes the tension of the wire drawing is not constant, which can cause the deviation of the outer diameter of the single wire can not be accurately controlled.

2. Tremor of copper wire on annealing wheel

This makes the copper wire in the loose and tight state of annealing, annealing current density is large when small, and the strength of the copper wire at a higher speed is relatively low, so easy to cause the copper wire on the annealing wheel ignition, the surface of the copper wire due to the effect of spark and uneven diameter.

3. Wear and tear caused by long-term use of main motor gearbox

This can make the speed of the fixed speed of the wire drawing wheel does not match the traction speed and the speed of the wire drawing, so as to form a single wire drawing.
Solution: the line storage device is well lubricated, to avoid its high speed running on the line caused by the opposite friction and then make the line thin; Adjust the tension of the wire, so that the drawing stroke is always close to the annealing wheel; Ensure that the steel ring of annealing wheel is in good condition and avoid the unstable annealing current due to the surface defects of the steel ring.
