The new EDER EDDS-2 innovation
allows marking and identification of
diamond/PCD drawing dies and other
costly tools within seconds.
This is effected by marking a small
specific and continuously individual
numeric DataMatrix code onto the
steel casings of the relevant tools in a
couple of seconds with high
precision, leading to their full
identification and allowing
administration of specific die-tool data
immediately.
Today, in modern wire drawing mills
and cable plants, various tens of
thousands of costly diamond/PCD
die-tools are in permanent use, asking
for collection and registration of lots of
information to grant trouble-free wire
drawing operations onwards. Property
data such as manufacturer, fabrication
number, die-tool material,
die-geometry, bore-size, delivery and
usage date, etc, has to be registered.
Likewise this has to be done also for
variable performance data, eg time/
endurance of die-applications,
number of repairs, usages with new
bore-sizes, drawing statistics, etc.
Until now, all this data has been
collected and registered statistically
by personnel onto paper in more or
less circumstantial and
time-consuming procedures, then
getting stored externally and with the
hope to get them on hand again when
being needed later on.
The new system from Eder, a family
owned company, simplifies this
collection of data. The marking,
reading and administration of all
important die-tool data can now be
executed directly in a short space of
time.
The new EDDS-2 device and system
uses a special dot-peening procedure
to mark a specific, individual numeric
DataMatrix code within seconds only
onto the casings of costly diamond/
PCD die-tools. Thereafter, all relevant
property and variable performance
data of these tools is registered into a
specific EDDS-2 software and can
easily be read and administrated at
any time.
The entire EDDS-2 system uses a
specially developed software which
can run on nearly all commercially
available computers and the specific
hardware components, such as the
Dot-Peening unit with an electrically
driven tungsten carbide precision
marking pin. Furthermore there is the
control board, the data read-out
device and the take-up carriage for
the dies to be marked.
The dies to be marked will be
supplied from a magazine towards the
marking position of the EDDS-2
device, where the marking pin will
dot-peen mark each one of the
relevant die-casings with an individual
specific numeric DataMatrix code.
After the marking, the dies, by means
of a conveyor belt, will be transported
to the read-out station, where the
marked codes will be checked for
their readability by a special
controlling device.
If the code cannot be read-out
properly, the relevant die-tool will be
automatically removed from the
conveyor belt and will be transported
to a separate collection area.
Thereafter, a proper code-marking of
this tool can be undertaken.
