Optimised
processes
for tube
bending
and forming
TRANSFLUID Maschinenbau GmbH
develops free-of-interface automation systems
from a single source, and ensures the optimal
set-up for the whole tube processing.
At the beginning of each transfluid
solution there are specific requirements.
“In this concrete case aluminium tubes of
17 x 1mm diameter were to be bent in a
bending radius of 10mm (0.58 x D),” said
Gerd Nöker, one of transfluid’s CEOs.
“The wall thinning on the exterior bend was
permitted a maximum of 30%. Additional
requirements were the possibility for a
bend sequence with various radii, end
forming on both ends and a cycle time of
maximal 15 seconds per component with
up to six bends.”
To speed up the tube bending process
and at the same time reduce handling
costs, transfluid developed a solution
that forms one side of the aluminium
tube before bending. After that, a 4-axle
handling system takes over loading the
fully electric transfluid bending machine.
The safe inward transfer of the 80 to
800mm-long tubes is guaranteed by
loading from a step feeding system with a
capacity up to 500 workpieces.
To ensure optimal quality upon
bending, the length of every tube is exactly
checked before feeding. The bent tubes
are then removed by a robot and fed into
a combined transfluid forming machine. In
one step, the chipless cutting of overlength
takes place as well as simultaneous axial
forming. Subsequently, the robot feeds the
single tubes to an optical measurement to
completely control the forming geometries
and surfaces.
The integrated transfluid automation
system (t motion) can also process very
short parts that, on customer request, are to
be end-formed on both ends after bending.
For this, the forming machine is equipped
with an automatic clamping jaw changer.
This allows quick changing between two
different form clamping pieces, according to
requirements.
