In 2014 Maschinenfabrik Niehoff
introduced its completely new developed
MSM 86 type rod breakdown machine
at its factory in Schwabach, Germany.
Designed for copper wires, the machine
can also be used for wires made of
aluminium, alminium alloys, copper alloys
and special materials.
Being of modular design, the MSM 86
offers users more options in terms of
process technology. The latest generation
of controls allows drawing/annealing
with minimal slip, resulting in high quality
wire surfaces. The optimised wire path,
innovative drawing die holders with
high-pressure cooling of the drawing dies
and an optimised wire cooling/lubrication
due to the fully submerged drawing basin
contribute to a high wire quality.
Capstans which are not in use are
switched off. In addition, design changes
have been made to reduce maintenance
work requirements and make the access
to the relevant areas easier. A quick
drawing die change system reduces
downtime when changing the machine
setup for different dimensions, and
enhances productivity.
Other features are an ergonomic and
user-friendly design and a highly reliable
separation of drawing emulsion and gear
oil by mechanical sealing enabling easy
maintenance and long maintenance
intervals. The total energy consumption of
MSM machines is up to 20 per cent lower
than that of rod breakdown machines
with conventional drives.
The MSM 86 is designed to be combined
with the new R 502 continuous resistance
annealer. With an annealing power of
600kW it is the most powerful annealer
made by Niehoff so far and is suitable
for combining with MSM 85 or MM
85 rod breakdown machines. Power
consumption is reduced by 20 per cent
compared to state-of-the art DC annealers
due to the newly developed voltage
control system NAC (Niehoff Annealing
Controller) and the AC annealing
principle.
The rod break down line – a 13-draft
two-wire MSM 86 + R 502 + SND 801
+ SPH 1001 rod breakdown line – can
produce, for example, two wires with a
diameter of 2.6mm at a production speed
of 24m/s resulting in an output of eight
tons per hour.
The SND 801 automatic double spooler
is designed for a larger wire range
(diameters of 0.8 to 4.5mm for copper
wire and 1 to 6mm for wire made of EC
grade aluminium and aluminium alloys)
and can transfer the wire automatically
from full to empty spool with very high
transfer safety. The operator-friendly
spooler also enables easier foundations.
The SPH 1001 automatic single portal
spooler features automatic spool
changing for increased productivity of
the overall line. The SPH 1001 spoolers
are built in two versions. Both versions are
suitable for spools with 1,000mm flange
diameter or less down to 630mm flange
diameter. In this case a lifting table is
necessary. The difference between both
spoolers is the degree of automation:
While the fully automatic version
works with automatic wire and spool
handling, the semi-automatic version is
characterised by manual wire handling
on the one hand, and automatic spool
handling on the other. The electrical
system, with independent PLC, enables
flexible integration of the spooler in any
kind of new or existing drawing lines.
The MSM 86 rod breakdown line is
operated by means of the new NMI
(Niehoff Machine Interface) 15" colour
touch-screen display with user interface
and simplified navigation structure.
