Straight Line Wire Drawing Machines were developed for
straight or deflection free drawing of wire to provide better drawability
lower frictional contact and lower operator interference.
Theoretically there is no limit as far as the wire material or wire
diameter is concerned to be drawn on these machines. ASSOMAC has pioneered
to indigenously develop the Straght-Line Wire Drawing Machine Technology in
India. Presently the range available is capstan diameter 900mm, 750mm,
600mm, 550mm, 500mm, 460mm, 400mm and 300mm for inlet wire diameter 16mm
down to 0.5mm. Line speeds upto 22 Mtrs / Sec.
These heavy Straiht Line Wire Drawing Machines provide remarkable drawing
performance for Low, Medium and High Carbon Steel Wire, Stainless Steel Wire
and special Alloy Steel Wire and Non-Ferrous Alloy Steel Wire.
This machine has a sensor roller between the drum and the next die such
that the wire passes in contact with this roller. These rollers have sensors
to detect the position of the arm and maintain tension on the wire by
regulating speed of the drums. The drums of this machine are inclined to the
vertical axis to effect fill on the drums. Principally this machine is best
suited for thick wires.
Features of Straight Line Wire Drawing Machine:
- Machines are built on modular structure, in combination of Blocks and
do not require any special foundation.
- Better productivity due to higher drawing speeds due to twist-free
operation.
- Easy operation and faster threading.
- High pressure Narrow gap, internal water cooling for high efficiency
cooling of wire.
- High degree of reliability - low downtime due to lower no of wear
parts.
- Much better finish wire quality due to a gentler handling of the wire
during the drawing process (less wire deviations, low torsion etc.) as
well as an optimized wire cooling.
- Pneumatic high speed brake system.
- Better environmental conditions due to increased dust protection.
- Greater flexibility and lower current consumption due to modern AC
drive technology and efficient power transmission system.
- PLC based control with profibus digital communication and fault
diagnostic system.
This type of Straight Line Wire Drawing Machine has the
drums in vertical axis without any incline the wire transfer happens through
two fixed pulleys and on moving pulley mounted on a dancing arm. This
dancing arm is either spring loaded or pneumatic loaded with sensor to
provide
There is a constant length of wire on the drum and the wire from drawing
drum is transferred to the next die through the fixed pulleys and the dancer
pulley in the inclined plane.
This machine is particularly suitable for Wires below 4 mm diameter and
necessarily required for wire sizes below1.5mm. Other features, fitments,
optional attachments remain same as offered along with Straight Line Sensor
Control Type Machine.
Assomac offers wide range of high speed state of the art
study. O.T.O./ B.B. Type Wire Drawing Machines. The construction of the
machine is such that it can withstand rugged workshop conditions of Wire
Drawing Plant and can guarantee the performance and accuracy with least
maintenance. These O.T.O./B.B. Type Dry Wire Drawing Machine have wide field
applications in Stainless Steel, High Carbon Steel, Alloy Steel, Mild Steel,
Copper Wire Drawing. The wire is drawn through a die which is fitted in
independant Die Box and is accumulated on the Block, and later being taken
through the OTO Pulley to the next Die. BB Block is Twist Free Type Machine
with Free Bobbin Block for accumulation and transfer to next block and is
better for higher speed & better finish materials.
