3. Summary
Wire drawing main machine motor,fixed speed wheel traction wheel
motor and take up use AC motor,driven by Siemens frequency
conversion device. The whole set of machine is controlled by
Siemens PLC,with good synchronism,constant tension,reliable
performance.Use touch screen to operate.Meanwhile,according to
tested line speed,PLC calculates required annealing voltage,proving
copper wire to make annealing at the best.
4.Annealing device
Structure:horizontal
Annealing way: AC three sections
Transmission way: Main machine is driven through belt
Max. Annealing electric current:5000
Max. Annealing voltage:55V
Annealing wheel dia.(norminal diameter):Ф450mm
Annealing wheel ring material:cold rolled nickel strip
Middle guide wheel uses LY12 surface spraying ceramic
Compressed air consumption: about300L/min pressure is bigger than
0.8Mpa
Inside heat exchange cooling water consumption:about 250L/min
temperature is not higher than 25 degree
Cooling water pump type:80-65-160
Plate type heat exchange(20㎡)
Bearing uses NSK brand
Structure charactersistics
Annealing copper wheel bearing seat uses flange to position,proving
copper wheel to be on same plane,good repeating positioning,easy
for maintenance.
Three phase AC annealing,energy consumption is 10% lower than DC
annealing
AC original side voltage regulation,controlled silicon electric
current is small,low heat,long lifetime
Upper annealing wheel has circulation water cooling,lowering copper
wheel,bearing and nickel belt temperature,increasing lifetime.
Carbon brush wheel uses air cooling.
