Over the last few decades, the evolution of press
brakes has been phenomenal. These transitions
have given birth to lots of different types of
press brakes, from mechanical to hydraulic and
now to electric. The best machines have quality
parts like Amada parts and Mazak parts for
efficient results. There are a lot of assumptions
about the speed, precision, and convenience of
electric machines. These machines dont have
hydraulic oil or associated seals which simplify
their maintenance.

They offer high-speed operation where the ram
descends quickly to stop at a pre-defined
bending speed position and then goes down to
bend the work-piece and then comes back up to
the top dead center. In electric brakes,
optoelectronic mixes safely and closely with the
control, so much so that a light curtain or
similar device has no effect whatsoever on the
cycle time of bending. And we can quite frankly
say that for the electric press brake safety does
not necessarily mean sacrificing cycle time. 1)
Crowning Alternative In the hydraulic systems,
the tonnage comes through hydraulic actuators
from any one side of the machine. This means that
as the ram comes down, gets in touch with the
metal workpiece, and encounters resistance, the
press brake bed bends. It creates a deflection
that gets dealt with a type of crowning
system. In the type of the press brake machine
i.e. pulley-driven electric press brake, the AC
servomotors drive a double pulley system
extending across the length of the press brake
ram. The number of pulley blocks varies
according to the machines size and power
requirements.

Belts are thick and are made of 0.12 inches wires
which are strengthened using a material coating
of polyurethane the same ones used in elevator
systems. AC servomotors drive the double pulley
system on four axles and balance fixed and
flexible rolls. These rolls are useful to adjust
and distribute the tonnage evenly. Hence, instead
of force coming from two hydraulic actuators on
either side of the brake, the pulley and belt
drive system distributes force evenly across the
ram length. This technology helps with on-the-fly
adjustment to ensure even force distribution
throughout the bending cycle. This will not stop
the lower beam from a deflection. The lower beam
has an identical system of pulleys to distribute
force, but this makes press brake very
unconventional and costly. And there are the
some options when it comes to machines that have
quality parts like Mazak parts and Amada parts
and would still fit your budget. Due to this
reason, some electric press brakes have low beams
and interior subframe. The exterior beam
material is stiff which minimizes deflection.
But, the interior subframe is tough to absorb
deflection. The design of this subframe is such
that it is

tough and stiff. This ensures the subframe
structure is flexible and deflects sufficiently
for the proper machine tonnage. 2) Safety The
goal of any press brake machine is to produce
parts perfectly, quickly, and safely. Earlier
machine designers were trying to perform a
balancing act between these three factors while
some times promoting one factor at a time. But,
with the current electric press brake machines,
these three things are easy to handle and juggle
between. Considering the safety measures, many
press brake machines enhance safety measures in
the front, side and behind the press brake
machines. In some cases, high and low adjustments
are safety enhancement types. With time,
introduction to new things takes place and one of
these is light curtains. The advantage of using
a light curtain is it brings flexibility, laser
guarding, and camera-based systems. Laser and
camera-based systems travel along with ram and
work at the bottom of the tooling.

Optoelectronic safety devices in combination with
traditional and mechanical safeguards to side
and behind the work envelope. In the long term,
it has turned out to be an incredible and
effective solution. But, even today with time,
these products require slight efficiency
sacrifice. Driving systems on most of the press
brakes are either hydraulic or mechanical. In
such cases, optoelectronic safety systems tell
machines to stop when a beam or vision path is
broken or when the ram returns to the top dead
center. In such instances, the electronic system
interfaces with the hydraulic or hydro-mechanical
system. 3) Speed with precision Press brakes
remain common in metal fabrication. It is a long
and tardy task to form a part then cut it.
Additionally, nowadays it is even more difficult
to find skilled and experienced operators.
Working with a press brake can be difficult for
many experienced operators too. These days
offline programming and real-time adjustments on
the brake take up minutes instead of hours of
long setups. Also, they are now long-lasting
considering their quality parts like Amada parts
and Mazak parts.

Final words Today with constant revolution and
emerging technology, electric press brakes are
the latest evolution of bending machine tools.
There are many other machines with safeguards
placed and are fully functional. This new
technology makes the bending process faster,
accurate, and safe. This Article Post is
