Press brake
press force: 290 tons
Machine still assembled and fully functional
Machine was delivered in February 2020 and has only run a little since
then.
The operating hours are: 545 operating hours
Dismantling, collection, transport, reconstruction and commissioning
by the buyer.
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.

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.

- 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

- 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
