Targeted Solutions For Frequent Wire Breaks In Multi-Head Wire Drawing Dies

1.Raw material control ‌ 

Strengthen the incoming inspection of copper rods, control the oxygen content to be ≤500ppm, and remove the billets with inclusions and cracks.

2.Drawing die optimization ‌ 

Reconfigure drawing dies according to process requirements (for example, adding bridge dies for rolling bars), and regularly polish or replace worn dies 68 Select dies with short diameter zones and surface finish meeting standards to reduce the coefficient of friction.

3.Process adjustment ‌ 

Calibrate the tension system: ensure the stable air pressure of the wire storage device, and the number of winding turns of the tower wheel is reasonable. 

Control the stretching ratio in passes, and the cumulative deformation does not exceed the material limit (for example, 2.53mm copper wire requires 8 dies).

Synchronize the annealing current and drawing speed to avoid sudden current changes.

4.Lubrication management ‌ 

Daily test of emulsion concentration and pH value, remove metal shavings contamination, and regularly replace deteriorated oil. 

Optimize the oil spill prevention design at the outlet to prevent poor lubrication.

5.Equipment maintenance ‌ 

Regularly inspect the transmission components (gears, belts), replace worn parts and replenish lubricating oil.

Clean the surface of the tower wheel with alcohol and repair the burrs on the deformed winding reel.
