the main machine features guaranteeing
a long service life even with multi-shift
operation.
The machine is able to safely and precisely
bend tubes up to OD 30mm, with a
maximum bending radius of 200mm. The
Tubotron 30 has a maximum tube feed of
1,600mm/s, while the maximum bending
speed is 150º/s. The machine also operates
with a positioning accuracy of ±0.05º (mm).
All functions are automated, and the axis
speed can be programmed arbitrarily.
The tube bending machine has an
exposed, compact bending head that
leaves a maximum free bending space.
The hydraulic long-necked collet chuck,
with bent tube re-feeding feature, can be
positioned safely within the sliding piece
area, ie before the last bow.
After bending, the steel tube frame is
taken out by a gripper and transported
to the deposit table while the next tube
is already available for feeding into the
bending machine. This manufacturing cell
enables the customer to produce complex
tube bending parts almost automatically (ie
without operator) at minimal lead time and
maximum machine and repeat accuracy.
Due to the sophisticated combination of
robustness, rapidity, precision and reliability
a maximum rationalization and automation
of the tube fabrication process is achieved.

3R Software Solutions, Germany, have
developed a piece of machine-independent
software for the simulation of bending
processes, branded Kolli. It examines
whether individual pipes can be fabricated
on a bending machine and supports the
operators by calculating the necessary
data.
When linked to a CAD system, entire pipe
systems can be checked with the software.
Only the machine type that is to be used for
bending is defined. It is also possible for
Kolli to be integrated into the 3R software
framework.
Kolli can provide solutions for potential
collisions. One approach is to extend the
straight part between two bows, which will
be cut out after bending. This can lead to
just one weld which is less effort than two
welds, the result of using an elbow.
Unison’s all-electric tube bending machines will revolutionise
your tube fabrication operations. Servomotor bending axes give
you complete software control of the process. You can bend with
enormous precision. Scrap is virtually eliminated! And anyonecan set-
up the machine automatically, and repeat configurations at will.
The all-electric machine will also slash your electricity costs, as it
only consumes significant energy when actually making a bend. On
a customer comparison with an equivalent hydraulic bender, our
machine consumed 90% less electricity!
Choose Unison - the inventor of the all-electric tube bender - and you
will see a genuine return on your machinery investment. We have a
large range of machines for 10 to 150 mm diameter tubes.
Tube bending,
as it shouldbe.
