Induction spool bending
machines
COJAFEX has introduced a new line of
smaller-sized spool bending machines
for diameters ranging from 2" to 24".
The PB450R for pipes up to 18" is the
larger brother of the PB Special model.
“We are very happy with the PB
Special, which we have had for 15 years,
and the addition of this machine allows
us to serve a significantly larger market,”
said Tormod Lie, CEO of NIRAS, after
installation of the first PB450R.
The machines are designed to
automatically create spool pieces with
bends of 1.5 DN and greater. Spools
can be made out of standard pipe,
eliminating the need for elbow fittings.
This reduces the cost of bevelling,
welding and inspection.
“The PB450R has been designed to
outdo its predecessors on performance,”
commented Mr Alders, technical director
of Cojafex. “It can process 50 per cent
stronger pipe and it has 55 per cent
more induction power. Manipulation of
the pipe in between the bends is also
significantly faster thanks to the ability
to rotate the pipe 180° in one go.”
Pipes are automatically loaded and
positioned into the machine by a pipe
feeder, eliminating the use of cranes
during loading and reducing the load
time to less than two minutes.
“Because of market demand Cojafex
is currently engineering a PB600FBR
for pipes up to 24" and a PB100R
machine for pipes up to 4" along these
same lines,” said Mr Alders. “This is a
welcome addition to our standard line of
machines, which goes up to 64".”
Induction bending is a method of
producing pipe bends in a wide range
of materials. It is claimed that induction
bends can be produced more accurately
than their cold bent counterparts and
with better wall thinning and ovality. A
free choice of radius and angle takes
away the design limitations of spools
made with fittings, and this can be done
without investing in costly additional
tooling.

7-axis all-electric tube bender
LANGBOW Ltd is the sole UK supplier
of SOCO machinery, including the SB-
32x7A-2S-V-U.
This CNC tube machine features
an all-electric tube bender (seven
electric servo control axes), which is
equipped with left and right bending
technology for maximum flexibility and
minimal interference, with capacity up to
32mm OD.
The new SOCO CNC tube bender
combines draw, roll and dual direction
bending way technology. The line is
suitable for complex parts and shapes,
such as automotive exhaust pipes, and
health care and fitness equipment. It
is equipped with seven electric CNC
axes and 2+2 bending stacks, and
uses SOCO’s DGT technology (direct
gear transmission) for high speed and
accuracy.
It may also be optionally provided
with automatic loaders and automatic
unloaders for full automation. The
company states that the tube bender
can offer one of highest performance
solutions available.
The machine features bending,
rotation, feeding, machine head seat
horizontal moving, machine head
rotation, clamping die, and pressure
die clamping, along with left and right
bending capabilities in the same cycle.
Other features include easy
programming, automatic mandrel
lubrication, touch screen with industrial
PC, and multi-stacks/multi-radius.
