Simplifying tube processing with
automatic tool change system
BENDING of tubes with diameters
of up to 127mm is becoming more
demanding. “It isn’t only about
implementing technical efficiency in
processes or machines anymore,” said
Stefanie Flaeper, managing director at
transfluid. “No matter the time efficiency
and precision, the solution must be
controllable.”
The specialists from Germany have
developed the tube bending machine
t-bend DB 40120-CNC-VE, to permit
bending radii of 1 x D at very thin wall
thicknesses for such tubes.
In the scope of a current project, the
setup of this special bending system has
been implemented fully electrically. All
movement axes are optimally
synchronised by the special
transfluid sequence control or
can be programmed controlled
against each other. It is also
possible to easily optimise
the process via this sequence
control, which effectively
improves product-specific
cycle times.
All parameters can be taken
from the CAD and necessary
form clamps are integrated in
the automatic sequence.
The transfluid engineers
have implemented reduction
of the follow-up costs by using an automatic clamp die change system.
The time frame for tool change is
comparable to that of a radii changer.
The new DB 40120-CNC-VE has
two tool levels. It is able to change the
clamp dies eight times, so that each
tube can be bent even in highly complex
geometries. This form of tool equipment
is efficient, reducing follow-up costs to a
an absolute minimum.
“In particular because the diameters
are relatively similar and radii are
very tight with 1xD, only the bending
geometries really change in new
products. This means that only new
clamp dies need to be used,” explained
Ms Flaeper. To implement the tight radii
at a relatively thin wall thickness, the new
tube bending machine has an additional
boosting device that can support even
the last bend at short rest lengths.

Tube-o-Test from ANUP NDT
ANUP NDT PVT LTD, based in Pune,
India, offers the Tube-o-Test System,
which is an encircling coil-type eddy
current test system with on-line and off-
line options.
The system can be used for eddy
current inspection of steel, stainless
steel, copper and cupronickel tubes.
ERW as well as seamless tubes can
be inspected. The system can fulfil any
international standard with drill hole
reference.
The Tube-o-Test comes with
advanced embedded system and is
highly reliable, user-friendly and cost-
effective.
The Tube-o-Test and its accessories
are already in use in South Africa,
the UAE, Oman and extensively in
India.
ANUP NDT PVT Ltd provides
efficient and reliable support to tube
manufacturers for eddy current testing
needs.
