At its October trade fair in Germany last
year, Zwick introduced a new testing
machine for evaluating the mechanical
deformation of sheet metals.
The new hydraulic BUP 1000 machine
addresses the latest requirements of
the steel industry, especially for use in
new automotive applications where
higher tensile strength combined with
high formability has become more and
more important.
Forming behaviour has to be
characterised, both for the modelling of
newly developed products, and for
quality assurance/production control.
The machine can be used to determine
the forming limit curve (FLC) and, with
drawing forces up to 1,000kN and a
punch diameter of 100mm, meets the
latest requirements of ISO 12004.
Building on Zwick’s global lead in
automated test equipment, the system
uses digital PLC technology enabling
the test to be controlled from either
the force or punch displacement
measurement channel.
The advantage is that standard tests
can be easily carried out, and in addi-
tion, the large punch displacement and
wide speed range offers a range of
useful applications including small
scale simulations of the complete
forming process.
Data acquisition is under the full
control of Zwick’s standard hardware
platform test control electronics whilst
data is processed and analysed, and
organised through the testXpert®
software.
With its remote control capability
of the function display unit, and the
hydraulic operation of the tool head
aiding the insertion and removal
of test specimens, the system offers
significant and powerful benefits.
