Tensile Specimen Punches / presses
Since 1970 in sheet metal industry we are the first address for specimen
preparation machines. Totally we supplied 80 % of all equipment used in
the market. When someone is talking about specimen preparation machines
the opinion are machines from
From
coil to high quality specimens within 3 minutes !
The punches / presses are especially designed for to prepare specimens
in testing industry. To limit the costs of this machine we designed this
machine especially for this application. So this machine can’t be used
for other applications. But on the other hand: Very often this equipment
is less expensive than used presses (with of course higher stroke).
In the last years the sheet metal industry and steel market designed
more and more specialised steels with micro structure. At this material
the tensile strength and also the total elongation increased to a level
that no one did estimate 10 years before. Because of this today a 1,000
or 1,200 kN press became standard equipment for this application.
The limit of these systems is inside of the range of 0.05 – 8.0 mm
(0.002 – 0.3”).
It is not possible to use only one tool for a very
big range. In nearly every case there are two ore more tools needed.
Even when austenitic material has to be cut the steps of thickness
ranges has to decrease to 50 % because of the “incredible” deep drawing
effect of this HQ material.
In former times we designed presses
in C-shape only for 600 kN (60t). Since we are using FEM we designed
C-frame presses up to 2,500 kN (250 t) with C-shape frame.
The
benefit of this machines is: You don’t need to pre cut the sheet metal
plate:
Put a not limited plate into the open shaped press and also
open shaped tool and receive within seconds a blanked tensile specimen.
These C-frame presses we

in 2008 / 2009 we built for customer
SHOUGANG CHINA
.full
automatic specimen punch system. -
at 15 rolling lines sample
plates will be cut
-
these will be labelled with barcode
-
in special container (fitting to punching system) plates will be
delivered to system
-
containers will placed into the system
-
the robot (with label reader) identifies the specimen plate
-
system requests (with label-info) from HOST the thickness /
dimension of plate
-
specimen plate will be gripped by vacuum griper
-
dimension and thickness of plate will be controlled by sensors
-
label for identifying tensile and circular specimens will glowed at
label station
-
depending on needed specimens shape and thickness range the plate
will inserted into one of 7 different tools of the system:
- ISO / ISO6892
- JIS -
blanked specimens falls on a slide, user can pick it up easily
(while system runs)
-
waste material will be taken to waste container
-
a new cycle will start
