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 systemuses
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.
