Machine description
The machine is a robust welded construction
The hydraulic pistons are made of high-quality steel. The surfaces are hard chrome-plated for wear protection
The position of the cylinders is controlled by two proportional valves. The valves are mounted directly on the respective cylinder
Two independent position measuring systems recognise the current cylinder position and transmit this to the control system. Any bending of the machine is recognised and compensated for by readjusting the cylinders
The rigidity of the machine is increased by side-welded cheeks
A double roller guide ensures precise and torsion-free movement of the folding beam and allows different in feeds of Y1 and Y2
The bending beam is also guided over guides made of composite material
The machine's stop system is equipped with two stop fingers
The machine complies with the CE standard
X-stop
The stop is equipped with two laterally adjustable stop fingers. Two linear guides ensure precise bearings and highly accurate positioning of the stop
It is driven by means of two driven ball screws
R - A c h s e (optional)
The automatic height positioning of the connections takes place via a
double rack and pinion drive. Both stops are driven simultaneously via a cardan shaft
driven simultaneously
ROL 1 clamping system (optional)
ROL 1 is an innovative solution for tool clamping to increase the productivity of a press brake

ROL 1 KDS clamping system (optional)
ROL 1 KOS is the further development of the ROL 1 system. Thanks to an additional
clamping plate on the back of the tool holder
the tools can also be rotated

Fissler AKAS Ili light barrier
The AKAS Ili system unit is a special protective device for press brakes and press brakes
press brakes. It consists of a transmitter and receiver
The AKAS Ili transmitter generates two modulated
visible red light laser beams
The AKAS receiver consists of three receiver elements and evaluation electronics
The transmitter and receiver are permanently connected to the upper beam of the machine and form a LASER optical safety edge in front of the upper blade
The AKAS forward-running LASER optical safety edge keeps the hands free for
the handling of the sheet metal parts with simultaneous shouldering of the links during the
the entire bending process
The AKAS Ili transmitters and receivers can be quickly and easily adjusted to other tool lengths
automatically adjustable
Depending on the maximum overtravel of the press brake
AKAS Ili can be programmed in such a way that optimum productivity is achieved through maximum rapid traverse or minimum creep distance of the press
Operating the machine
The machine is operated via an industrial computer. The control system
enables three working modes
Manual
The lifting ram only moves when the foot pedal is depressed
Semi-automatic
A complete bend is processed after the foot pedal is released
automatic
A complete bending programme is executed after the foot pedal is released
The control system
Boschert uses the Cybelec DNC 60 alphanumeric control as standard
As an option
Boschert uses
among other things
the Cybelec
Modeva PAC or the RA 3D
both with 15" touchscreen
These controls have been specially developed for sheet metal bending applications
Simple operation
Intuitive programming with clear
easily recognisable
colour-coded field functions
Complete programming of the factory settings via just one programming page
Fast machine setting thanks to direct access to setting parameters and basic functions
basic functions
Fast data entry thanks to the ergonomic
slightly inclined keyboard with large
large keys
Convenient operation thanks to 15" TFT touch screen
The important machine elements (pushbuttons
switches) are positioned within easy reach directly 1
placed directly below the keyboard
Better bending
The control system has offline 2D software for preparing production programmes on the
programmes on the PC and for checking the possibilities for workpiece
workpiece coloring in the Boro
Higher productivity through quick and easy modification of existing products
High-precision control thanks to extensive machine parameters
Display of error and warning messages on the console screen
Wide range of functions
2D touchscreen control with large 15" screen for display and multiple simulation
multiple simulations. The optimum bending sequences
the tools and the sheet
the sheet position in the tools and collision warnings are displayed
according to criteria defined by the operator
o minimum sheet length on the operator side
o minimum bending tension
o maximum accuracy between two defined sides
o simple handling
Multitasking and file management under Windows XPe
Management of CE safety cycles
Simple communication
o Windows networking via Ethernet (RJ45)
o Connection of external devices via USB port for software updates and data backup
data backup
o Telephone service
