The
main body with base is of close grain Cast
Iron construction and generally built with
spaced walls and ribs to ensure proper alignment
and rigidity.
Drawing block is made of specially Graded Casting, hard Metalised and Ground
at wire line to increase abrasion resistance. Gear of Phosphorous Bronze and
Worm is High Carbon Steel immersed in oil bath reservoir in the body of the machine
to absorb its heat of action while in load to maintain a longlife of gear set.
Shafts
and worm are fitted with extremely heavy duty Ball and Roller Bearing. Oil
seals are provided where necessary. Die and Block are water cooled, arrangemehts
of water circulation fitted inner side of the drum for cooling the drum and
intensive
water cooling arrangement provided for the Die box to ensure life of dies.The
machine is supplied with guards. |
The
raw materials, (wire rod) is Pointed
in the pointing machine and inserted
through the Die positioned in the Die
Box of the 1 st Wire Drawing Machine.
The end of the wire inserted through
the Die is fastened to a locking device
attached to the drum. The drum is set
into rotational motion, by the push
bottom starter.
The end of wire fastened to the
block attached to the drum gets pulled & coiled around the Drum since the
wire is getting pulled through the Die having higher inlet dia and lower outlet
dia. the drawn wire diameter gets reduced. The starting end of the drawn wire
is released from the lock of the 1st drum, is passed through the overhead loop
and continuous pulley on the Drum and brought down and inserted through the Die
of 2nd Drum and drawn through the die for further reduction. Thus the wire is
drawn through all the wire drawing drums of a set in a continuous manner to get
the required finished diameter of Wire.
When the drum of the last wiredrawing machine in the set gets fully loaded with
the drawn wire, the machine will be stopped to unload the finished materials
and then re-started.
When raw materials one
Budle finishes, the machine will be stopped and the end is welded to one end
of another fresh bundle by the welding machine and the Process continues. Also
in case of accidental snapping of wire between any of the drums, the snapped
ends are welded by the help of the welding machine for continues processing. |
