Por table measurement system expands
oppor tunities for bending tubes
OBTAINING exact measurement data
for component production, reverse
engineering or component inspection is
especially particularly useful for creating
valuable results during tube bending.
For this reason transfluid Maschinenbau
GmbH has developed ‘t control’,
together with a partner.
The wireless system for measuring
tubes and connection elements such
as flanges does not need arms, joints
or laser beams and measures via an
exactly defined light pattern, which is
observed by one or more cameras that
determine the position and orientation of
the light pattern in space. This enables
the desired raw data to be recorded.
Corresponding interfaces allow
exchange of data with CAD and
transfluid’s ‘t project’ bending program,
and direct integration of the tube bending
machine in the process. The overall
system therefore increases flexibility.
t control is portable, ensures a high
level of precision in the measuring space
(directly at the object), and is suitable for
use on construction sites.
No calibration is necessary and t control
is ready to start within five minutes,
with up to 20m of measurement power.
Depending on the requirements, this is
implemented via tactile measurement
with standard measurement sensors or
tube measuring calipers.
In addition to control measurements
for components, material correction
values for transfluid ‘t bend’ tube bending
machines can be recorded. In the area
of reverse engineering, simple existing
geometries can be measured in order to
reproduce them precisely.
Data for component production is
recorded by drawing a fictional tube
shape using ‘air points’ between the
connection pieces. This enables simple
and exactly matching tube construction
directly at the installation location.
Connections like flanges and screw
connections can be recorded and
processed digitally. This also includes
detection and bypassing of possible
projecting edges. The data exchange
with CAD and the connection with the
transfluid bending program enable the
geometry to be optimised, including the
bending collision test.
Over-bending values for the bending
machine can be recorded within the
scope of the component inspection.

A par tner in metal bending
FOR over 50 years Faccin SpA has
assisted manufacturers around the world
to solve challenging bending problems.
The company produces and sells
a wide range of bending machines,
including three models for bending thin
plates: HCU two-roll bending roll with
high speed and productivity; ASI three-
roll initial pinch bending roll; and 3HEL
electronic three-roll pyramid bending
roll with double pinch. For rolling
thicker plates, two different models are
available: 4HEL, a four-roll pyramid
electronic bending roll; and HAV, a three-
roll variable geometry bending roll.
Faccin also constructs and markets
various types of angle rolls that ensure
bending quality and productivity over
time: RCMI, specifically designed
for bending profiles with high flexion
strength modulus; and Taurus for
bending aluminium profiles and heavy
metal fabrication work.
The company’s dished heads
production lines include technologically
advanced presses, flanging machines
and manipulators that offer reliability
in terms of achieving tolerances and
lamination reduction. Hydraulic presses
(PPM) ensure forming accuracy, and
automatic manipulator (MA) handling
systems allow processing of several
plates at the same time. Flanging
machines (BF) offer high productivity
and quality of the final product, and the
hydroforming machines (PPH) are used
in the production of dished heads for
truck tanks.
Faccin has also developed a range of
special machines for specific needs in
the fields of pipe production, shipbuilding
and aerospace. These include the long
three-roll bending rolls of the HAV-2F
range, suitable for use in pipe mills; FB
angle rolls for bending bulbs and various
profiles; PPS Shipbuilding presses
for metal forming, levelling, bending,
curving and 3D modelling; large-sized
RP bending rolls that combine the speed
of a bending roll with the versatility of a
press brake; and the R line levellers for
processing plates of any length up to 4m
wide and up to 70mm thick.
