A par tner for tube and sheet metal forming
EBM is promoting itself as partner for all
tasks concerning tube and sheet metal
forming. As a manufacturer of electrically
operated or hydraulic-driven machines
and systems, the company offers
standardised and individual solutions to
suit customers’ requirements, with either
automatic or manual operation.
From planning of a product until start of
production, customers are supported by
30 years of experience with professional
engineering and R&D.
Ebm’s areas of business include
standard and special machines for tube
and sheet metal forming; tools for tube
and sheet metal forming; engineering
and service; and prototyping and
production of small batches. In the
field of tube forming, the company’s
programme includes machines for radial
forming, axial forming, cutting, rolling
and stamping.
One of its latest developments is the
C50VE electric-operated axial tube
end-forming machine with five forming
stations. The machines of the C series
are suitable for tube end-forming with
all metal materials. Processes such as
sinking, tapering, expanding, swaging,
crimping and calibrating can be applied.
Simple designs can be formed with just
one tool; for complicated designs, up to
five tools can be operated. The clamping
of 3D bent tubes up to a diameter of
120mm is possible due to the C-frame.
Other specifications of the C50VE
include tube diameters from 3 to 120mm,
80-500 kN forming force and 80-500 kN
clamping force. Numerous options are
available upon request.

Expanded prototyping
options for new pipe forming
geometries
PIPE forming technology is a complex
area, with ever-smaller tolerances for
advanced new projects from different
industries. Companies with fresh ideas
need to transfer new products to serial
production safely and reliably after
development.
Machine constructor transfluid uses
its pipe processing technologies for
research in its internal prototyping
department. In addition to sampling its
own new developments, for example in
the area of tool technology, companies
without machinery of their own can have
their pilot series analysed and precisely
improved at transfluid.
“Support in this area is in higher
demand than expected,” said Stefanie
Flaeper, managing director at transfluid.
“Therefore we have expanded our
research and prototyping department
once again just recently. We can perform
diverse tests on components and tools
with pipe diameters up to 65mm here.”
A CNC-controlled type SRM rolling
forming machine and two axial forming
machines are used, with a forming power
of up to 25 tons. The entire process
chain can be implemented with an
additional CNC-controlled pipe bending
machine and an orbital pipe separation
system, to ensure that requirements, eg
regarding burr formation, can be met.
For specific customer projects, the
experts in the department can test new
forming geometries and tool concepts
for serial maturity and quality. The
transfluid team relies, among others, on
a tactile and visual measuring system
for components and tools. The interim
results up to the certain result are
documented reliably.
The transfluid experts have special
experience as an initial developer of
incremental pipe forming, which permits
partial rotation-symmetrical forming
of pipes made of high- and very-high-
strength materials. In particular, review
and assessment with lightweight
components and high-strength materials
is possible. Depending on geometry, this
can even be done tool-independently,
and the company can offer pilot series
or prototype production.
