Servo-controlled stamping and forming machine
WITH the RM-NC Bihler presents an
entirely new generation of stamping and
forming machines.
The completely servo-controlled
machine is perfectly designed for the
economical production of stamping
and forming parts as well as wire parts
in all lot sizes. The RM-NC shows its
benefits especially for small and
medium lot sizes and for a large
number of different product versions.
Very short, 100 per cent reproducible
set-up and changeover operations are
its key strengths.
These are ensured by modern servo
technology in combination with the
intuitive control technology of the Bihler
VariControl VC 1.
For instance, the slide units can be
aligned in radial and linear direction
simply by pressing a button on the
integrated slide positioning unit. Rapid
tool change systems help to further
reduce set-up times.
The RM-NC is impressive also in terms
of productivity. Up to 300 manufactured
parts per minute speaks for itself. Costs
for new tools are reduced considerably
by the small number of components
while existing tools in the RM series can
easily be integrated.
The servo-controlled machine is able to
replace several mechanical machines
and allows users a much higher
creation of value.
Compared to conventional stamping
and forming machines, an output
increased by up to 200 per cent can be
achieved, lot sizes can be processed in
half the time and changeover times
reduced by a factor of nine.
Particularly time-intensive tasks such as
adjusting the material feed, positioning
the slide units and adjusting the
movements of the forming punch are
now completed in a matter of minutes
on the VC 1 machine and process
control system.
The servo-controlled processing units
guarantee a consistently high product
quality. All processing units are freely
programmable over the whole working
range. Working stroke, lower dead
centre, adjustment of the stroke
position and the motion profile can be
selected freely.
Forming movements can be executed
with constant transmission of force.

The new RT600 Eurolls straightening and cutting line for electrodes, capable
of producing welding electrode sticks at 10m/sec, was one of the major
attractions at Eurolls’ stand
at wire 2014 in Düsseldorf.
The full line, which includes
a seven step drawing line,
allows productivity to be
increased by placing Eurolls
CL25C33 cold rolling micro
cassettes instead of dies,
and is designed to process
low carbon or stainless steel
wire rod diameter 5.5mm,
draw it down to the final product diameters (2, 2.5, 3.25, 4, 4.8 and 5mm),
then clean the wire, straighten it and cut it in the two main product lengths
(350 and 450mm).
The main characteristic and advantage of this equipment is the capacity to
achieve high production speeds, maintaining the surface finish and accuracy
in stick diameter and length, requested for this type of material – basic
requirements to guarantee smooth operation in the successive steps of the
process.
