COnTInUUS-Properzi has designed
the latest state-of-the-art vertical axis
high-carbon wire drawing machine.
The logos II Evolution drawing
machine, with available capstan
diameters of 900, 760, 670 and
500mm, is the evolution of the world’s
most well-known drawing machine, the
logos. For decades, hundreds of
logos machines have been sold all
over the world, while keeping its main
configuration and legendary toughness
and reliability.
The new machine benefits from the most
modern design and construction
technologies and has been engineered
to maximise overall efficiency and safety
while minimising maintenance cost.
Here are some of the areas on which
the re-design was focused:
• High efficiency narrow gap cooling
system: the widespread system of
narrow gap cooling, which has
been one of the key factors of the
logos machines, has been further
improved to yield even higher
efficiency and better reliability
• Direct air cooling system: newly
designed air ducts allow lower
pressure losses which result in
higher machine performance and
improved wire quality
• High-efficiency transmission system:
the combination of high-efficiency
gear box, belt and pulleys results
in very low energy losses and
minimum required maintenance
• Pre-aligned modular frame facilitates
easier installation at customer site
• Easy maintenance: the machine has
been specifically designed to
minimise the maintenance and
facilitate better access to the
maintenance points in order to
reduce the down time
• Easy cleaning: the capstan/die box
area has been specifically
designed to easily eliminate the
dust, scale and lubricant coming
from the drawing operation,
thereby respecting the operator’s
health
• Compact design: the machine frame
has been optimised to reduce the
general dimensions of the machine
while keeping the ergonomics
unchanged
• High sensitivity speed control:
through a sensor arm on each
capstan
• Easy operation: short holing and
single jog (forward and backward)
of the blocks at each capstan
position
• Drawing capstans made of induction
heated forged steel yielding
hardness up to 62 HrC for
increased working life
• HMI: easy access to the working
parameters through the Operator
Control Desk
• Safety of the Machine: all the parts
of the machine as well as the
electrical control system have
been designed and built to ensure
the highest safety for the operator
• Soap Box refilling is possible while
the machine is in operation.
All of those result in a very innovative
drawing machine that, in the version
with 900mm diameter capstans, is
able to draw high carbon wire rod with
a 14mm diameter and perform at a
mechanical speed of 18m/s.
