Model
142-20/40 : Universal sheet metal test machine with fully
automatic test sequence
|
An extremely versatile test machine
for the medium to upper performance class ( 200
or 400 kN) which is suitable for applications in
the field of process control, but mainly used in
the research and development of new materials. The
machine is driven electro-hydraulically; the test
sequences can be controlled either automatically
or manually. The blanking press is integrated in
the test head; infinitely variable control of drawing
speed and blank holding force, independent of load.
Digital Display of drawing force, blank holding
force and punch displacement are shown with peak
value indication. Analog outputs or RS 232 C interfaces
enable force/displacement diagrams to be recorded.
As a further option, the control and regulation
of all main parameters and the evaluation of results
can be carried out via PC.

the material ofcylindrical deep-drawn cups. The
average cup height, the height of the ears in percent
and in mm can be read-off at the touch of a button
and are shown on the digital display instrument.
To enable additional data processing, the test instrument
can be equipped with interfaces, such as BCD or
RS 232 C outputs, and linked to printer.

Model
150 : Electro-hydraulic laboratory blanking press
|
Used for producing tensile test specimens
and circular blanks of ferrous and non-ferrous metals.
Tensile test specimens to comply with the specifications
of various standards or to meet individual requirements
can be produced using appropriate blanking tools.
The blanking stroke is initiated by two-hand controls
combined with a press safety relays. A force display
unit is integrated into the fron panel and records
the blanking forces. The blanks are discharges onto
a chute and are accumulated on the left of the instrument.
The blanking press is available in two versions.

Model
160 : Laboratory milling machine
|
Used for removing the work-hardened
edges of tensile testing specimens after blanking.
The tensile test specimens are clamped individually
or in packs into a milling fixture, then both sides
are guided past the milling cutter. The result is
a favourable parallelism in the measuring zone of
the tensile test bar. The speed of the milling cutter
is infinitely variable and can be preset between
approx. 4,000 – 8,000 min-1 achieving an optimal
cutting speed appropriate to the material.

Model
190 : Sheet metal marking instrument
|
Enables the electro-chemical
application of measuring grids using appropriate marking
templates which are available with circle diameters
from 2 mm upward. Sheet metal markings provide information
about the behaviour of sheet metal during forming. The
degree of strain due to elongation or compression is
clearly recognizable in direction and size on the basis
of the deformation of the applied measuring grid.
