Electric tube bending machine with
165mm three-stack capability
THE latest model in the all-electric
series from Lang Tube Tec GmbH is
the automatic tube bending machine
160CNC-EMR. This multi-stack and
multi-radius bending machine for
maximum tube OD 165mm (6.5”) is
claimed to be the only machine with
bending capability of three stacks of
160mm with 1D bending capability in
stainless steel.
The bender has 13 CNC controlled
axes including interpolation for cycle
time improvements and specific
bending cycles. The machine is suitable
for bending of parts for exhaust pipes
for buses, trucks or frame parts for
hydroforming applications.
For higher flexibility it is equipped
with a separate bend die return feature,
allowing return of bend die separately
from the bend arm, for increased
flexibility. For complicated part shapes,
a heavy-duty transport boost system
works with the heavy-duty rack and
pinion system to apply a boost force of
80kN or more, which allows minimised
clamp length and tight radius bending.
In order to speed up tool changes,
Lang Quick Tool features swing away tie
rods and slide in clamp die and pressure
dies. As an option, the machine can be
provided with an automatic tool changer,
allowing the change of pre-set tool
arrangements.
The CNC control installed on the
machine – Bend Motion Control – has
been upgraded with new features
to make operation of the machine
more user-friendly, with simultaneous
improvement of quality and productivity.
It includes Bend Motion Auto-Set-Up
for automatic set-up of new parts to be
bent, making set-up work independent
from operator skills.
The cycle time optimisation feature
Bend Motion Optimize calculates
the optimum movement strokes and
simultaneous axis movements of all 13
axes on the machine which, depending
on the part shape, can save up to 20 per
cent or more of cycle time. Bend Motion
Remote allows remote control of the
machine.
The machine saves around 65 per
cent of energy compared to a hydraulic
machine of the same size. Braking
energy is back loaded into the system
and there are no
potential hydraulic
leaks.
Maintenance is mi-
nimised by the use of
an automatic lubrica-
tion system controlled
by the CNC control,
with signals for re-
quired lube tank refill
and implemented self-
diagnostics.
A complete sliding cover minimises
space requirement on the shop floor,
and provides a high level of safety and
optimum accessibility for maintenance.
The machine is available in different
designs as single-stack machine, in
both bending directions or extended
bed length of 6,000mm (20 ft). As the
machine has been designed with heavy-
duty rigidity, it can also be upgraded
for applications for chemical plants
and shipyards. Accessory equipment
for complete automation is available
for the machine, such as automatic
tube hopper, weld seam detection unit,
tube auto loader, and robot loader and
unloader.
