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 version 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 boxes: refilling is possible while the
machine is in operation.
All of the above characteristics 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, thus
achieving the highest productivity in its
category .
