Laser
methods with
continuous
coil feeding
STEEL or aluminium blanks – used to produce stamped
parts such as car doors – can be cut using either dies or
lasers.
Laser blanking lines have the major advantage that no
investment is needed for buying and maintaining dies and
no production time is lost changing them – ideal therefore for
frequent product changes.
Schuler has unveiled a new line at ALS GmbH in
Dormagen, Germany, which combines cutting-edge laser
methods with continuous coil feeding.
“DynamicFlow Technology sets new standards in the
speed of laser blanking,” says Stephan Mergner, managing
director of Schuler Automation. “Thanks to maximum
flexibility and short set-up times, even small batches can
be produced just-in-time at low cost.”
Not only can the line be used to simultaneously produce
a wide variety of blank shapes, but blank contours can
also be optimised while production is running. “The result:
high output rates and tremendous flexibility,” summarises
Mr Mergner.
The laser blanking lines with DynamicFlow Technology
(DFT) are energy efficient and can process a variety of
materials, including high-strength steels, with a high degree
of repeat accuracy and edge quality. The patented process
is also particularly well suited to the production of surface-
sensitive outer panels.
There are no restrictions regarding the blank’s contours:
all sorts of shapes can be selected within a minimum of
time,thus greatly accelerating the tryout process. Thanks
to optimised blank nesting, the amount of scrap – and thus
material costs – can also be reduced.
During the presentation at ALS GmbH, customers mainly
from the automotive industry were able to witness at first
hand how the new line cuts blanks from a continuously
rolling aluminium coil. Schuler’s laser blanking line uses
three laser heads in parallel which can cut blanks with a
thickness of 0.8 to 3mm and a width of up to 2,150mm.
Thanks to their reduced dimensions (30 to 40 per
cent reduction), DFT laser blanking lines can be used in
restricted spaces and low-height production halls without
the need for foundation pits.
There is also a noticeable decrease in noise
emissions, thus reducing the need for noise protection
measures. “DynamicFlow Technology offers highly
flexible manufacturing conditions with comparatively low
investment costs and a high level of availability,” concludes
managing director Stephan Mergner.
