Drawing
5 - COURSE WIRE ( CW1, CW2, CW3, CW & CW5):-
5 - 1 Purpose:-
Objective of course wire machine is drawing Copper wire or Aluminum wire
from big diameter to small diameter.
Drawing Copper wire has diameter 8mm to many different diameter.
Drawing Aluminum wire has diameter 9 mm or 9.5 mm to many different
diameter.
If decrease in wire diameter then increase in speed of the machine.
If increase in final wire diameter then decrease in dies was used.
5 - 2 Advantage of drawing solution:-
1- Low temperature of mechanic tools.
2- Service life of die.
3- Quality of wire surface.
4- Cooling for die.
5- To making wire to slide inlet dies and capstans (pulleys).
6- Keep the color like sunshine.
5 - 3 How to operate Course Wire machine?
1- Put wire was drawing from upper diameter to different diameters in pointing machine.
2- Put the wire drawing inlet first die and does again steps 1 for second die tell final die (final diameter from final die).
3- Wire drawing passes the annealed and its advantage, the wire after drawing was became hardness and inlet in the annealed to become softness.
4- Take - up:-
a- It has tow spoolers (Tow bobbins).
b- Basket.
5 - 4 Shutdown of machine:-
1- Cut wire.
2- Friction in dies.
3- Friction in pulleys (capstans).
4- Shutdown in dancer.
