Schwarze-Robitec GmbH
Germany Hall 11 Stand C06
SCHWARZE-ROBITEC, a manufacturer
of tube cold-bending machines, will
present its broad spectrum of solutions
at EuroBLECH, ranging from tube
bending machines and fully equipped,
automatic tube bending production
lines to measuring devices and bending
tools, tube perforating and special
machines. Particular emphasis is
placed on energy-efficient solutions as
well as machines for bending new, high-
strength materials.
The company will present its
extended portfolio of bending machines
for processing tubes with diameters
between 4 and 420mm to specialist
visitors at EuroBLECH. Tailored to
the individual requirements of the
automotive, shipbuilding and offshore
industry, power plant construction, the
chemical industry and the aerospace
industry, the bending specialist offers a
range of machines and accessories that
can be configured in modules.
One major focus is on the
comprehensive advisory competence
for the different production concepts.
“Together with our customers, we
always produce an individual solution
that is tailored precisely to the needs of
the user,” said managing director Bert
Zorn. “This might be a newly developed
bending tool, a bending machine that
can be specifically configured, or even a
complete, fully automated bending line –
from tube separation through production
process to continuous quality control of
the bent parts.”
One significant topic on the Schwarze-
Robitec trade fair stand is the energy
efficiency of tube bending machines.
Different energy-saving concepts ensure
optimum handling of valuable resources.
As such, an improved energy balance is
achieved in the case of electrical drives,
including by the use of innovative feed-
in and recovery modules. Hydraulic tube
bending machines save energy, eg with
adjustable pump drives. Hybrid drives
also achieve convincing results.
“The purchase of energy-efficient
machines pays off not only in the light of
high energy prices, stricter international
legislation and increasing energy
awareness,” Mr Zorn emphasised.
“Investments of this nature are
subsidised in many cases – with certain
restrictions – by one’s own state or
by the EU through energy efficiency
programmes, or they are promoted
through reduced interest on borrowing.”
The processing of new, high-strength
materials is a second central focal point
of the trade fair for the tube bending
specialists; the cold reshaping of harder
materials requires significantly greater
bending forces. At the same time, the
materials react more sensitively.

Siempelkamp
Germany Hall 27 Stand D66
AT EuroBLECH 2012 in Hanover,
Siempelkamp will present presses for
the complete manufacturing process
of large-diameter pipes via C-, U-
and O-forming. As a single-source
systems provider, Siempelkamp not
only offers the machine engineering,
but also demonstrates the processing
technology for all three applications.
For O-forming presses Siempelkamp
has developed an improved control
concept: the incoming steel cannings
are generally positioned in the press
centre. Therefore, independent of the
length of the workpiece, the press force
is introduced exactly into the plate. This
results in a better load distribution and,
at the same time, a lower mechanical
load.
Furthermore, Siempelkamp has
optimised its proven tooling concept
featuring exchangeable shells. The
outline of the half-shells, which were
optimised with the finite-element
method, evens out deformations from the
tools in transverse directions. Combined
with the patented tool clamping, which
compensates the occurring forces in
longitudinal direction, Siempelkamp has
achieved the optimal pipe geometry for
the subsequent production steps.
Once more a new order of a long-
standing customer proves that
Siempelkamp has set the right course
with its C-, U- and O-forming presses.

Brazil. It will go on line together with the
O-press that had been ordered shortly
before. With a new control system it is
featured by particular energy efficiency.
