The hydraulic pipe benders of type series XOTH with CNC 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 15" color display the highest comfort with the touch panel and various key
versions and provide sufficient performance for particular applications. 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 bending disc works in one level and allows the separate control of various movements. Pulling-out
and lubrication of the mandrel is applied in bending of thin-walled pipes. CNC positioner performs clamping,
feeding and turning of pieces - three-dimensional bend.
The set of standard tools is composed of a bending disc, chucking jaw, carrying strip. The special tools
accessories offer mandrel of various shapes and configurations or slicker. The set of tools enables to exactly
copy various bends. The tools are fabricated as customized and based on submitted
drawing documentation for the bent part.
