Detail information of the machine
1. Brief introduction
The unit is used for copper rod cold rolling. Through cold rolling,
the mechanical behavior can be raised and the defects from casting
can be also fetched up. The producing capacity is 2.5ton / hour
when roll from Φ17mm to Φ8mm.
Mechanical design uses advanced crafts and high-quality materials,
such as roller; the appearance of the machine adopts German
design,which has higher work efficiency than other similar
products；Electrical parts assemble the imported parts from Japan,
which have safe and reliable performance, high technological
content; the whole production process is monitored by color touch
screen with clear data displaying, easy operating and high
automaticity. 2 high motive power frame copper rod rolling mill is
beautiful, efficient and durable.
2. Technical process
First, check the device to see if it works normal (including that
roll wheel stands must be fill with butter per shift, the sanitary
conditions of frame and each guide and so on); after ensuring the
normal condition of the equipment and safety operation, turn on the
power supply; wait for the console touch screen to enter into the
normal working screen, then open the oil pump. After the oil pump
starts working, lubricating oil flows into the 2 high motive power
frame. for a moment, through the transparent oil return pipe the
lubricating oil can be seen to come out from the oil return hole of
the motive power frame. At this time, open the rolling mill
operation ( as well as forward and reverse); and then open the
emulsion pump, wait for emulsion to flow out from each cooling
point of the 2 high frame and roll the copper rod; the rolling
speed can not be too fast at the beginning of rolling copper rod,
but it can be speed up to normal produce when copper rod comes out
from rolling mill and penetrates into take-up machine and coil
basket. after penetration take up and looping basket ,can increase
speed. turn into normal production. When finish, turn off the
rolling mill(take-up machine),emulsion pump,oil pump,main power in
order.
