The pipe benders of type series XOTH TB UNI with control system supplied by the company
BaR Automation are provided for cold bending of various metals with circular, square, rectangular
and elliptic section. The tools of special accessories allow bending of metal materials with
various sections to rings, elbows etc. The machine is conceived to enable simple control providing
necessary comfort and safety for the operator. Due to high productivity, simple adjustability and
reliable operation can be the machine used for small-lot and large-lot production. Due to high productivity,
easy adjustability and reliable operation can be the machine used in small-lot production and
large-lot production. The machine can be customized. The programming data can be acquired by performance
of bending in successive, semi-automatic operation. Principal fields of use: automotive industry
(gas outlets, frames and other products), furniture industry (metal furniture), engineering industry
(bicycles, air-condition equipments) incl. a lot of other industrial fields where are currently
used bent profiles.
BaR Automation control
The implemented control and visualization Power Panel is one of the latest systems.
Ethernet Powerlink installed in these benders for connection, synchronization and servo-converter control
is the first and single open standard of the industrial Ethernet in the field of the hard-real time.
The panels PP420 enable by the means of 5,7" color display the highest comfort with the touch panel
and various key versions and provide sufficient performance for particular applications.
In case of special order we can supply 15" color display similary with CNC machines.
Ethernet Powerlink is the bus for connection (in this case) of servo-amplifiers ACOPOS with the
PP420 control panel. The Power Panel is an operational unit for visualization and operation of the machine.
In connection with Ethernet Powerlink is transmitting the application instructions to the servo-amplifier
ACOPOS in strict deterministic and quick time cycles. Acopos as intelligent servo-amplifier synchronizes
all moves of individual axes without any support by the Power Panel. That is, the Acopos itself has a
built-in processor and can control speed and direction changes. By doing so it increases the capacity and
does not waste time with communication with Power Panel as superior unit. The principal advantage of the
applied design consists in complete system of automation components, simple software Automation Studio
that is used for control, visualization, moves and communication steering.

The machine works as semi-automat with manual feeding and automatic cycle for clamping, bending a
pipe releasing after bending. The bending disc works in one level and individual motions can be
performed separately. For bending of thin-walled pipes and closed profiles is used the mandrel or
bow ejector preventing the cross-section deformation. In this case will be the automatic cycle
completed by mandrel pulling-out. An electronic pre-selection allows programming various sizes
and angle succession of the required bending. The machine operation - motion pre-selection will be
panel programmed. The machine starts after tool arrangement with the actuation of combined driver. The
pipe bending accuracy can be corrected by appropriate tools.
The tools are customized as based on drawing documentation of the bent piece.
