Hydraulic Press Brakes - How it works
Santec Press Brakes have three
operational modes for operators' greater convenience and least fatigue,
which can be selected from the panel door mounted selector switch. These
operational modes are:
This mode is used for setting bed angle depth stroke. The ram movement (up
down) can be controlled at any described position from foot switches.
This cycle (Approach-Pressing-Return) is continuously repeated once this
cycle is selected. This mode is useful for continuous repetitive work where
stroke length can be adjusted to suit the job and the operators speed and
This mode is used where high production is suggested.
Working of Hydraulic Press Brake
Hydraulic presses are able to adjust the status of the upper cross-beams,
but this provision is also referred to as top dead center. At the time of
pressing the pedal or button two-handed control yoke begins movement down to
a certain speed. This speed is usually higher than the speed of direct
bending process, so that movement is happening to a certain point of
switching speed and speed is called free fall. This is also a conditional
term, because in reality, no drop traverses does not happen, because the
hydraulic system through the regulation, the rate is fixed in a certain
Having reached the point of switching speeds, the system control shifts to
a lower speed, called the working speed. In point of switching speeds are
also synchronize the movement left and right hand cross, which compared the
testimony with linear displacement sensors and signals are given for the
required adjustment to the hardware management - servo to adjust the rate of
delivery of oil in the working-cylinder machine. After a change of speeds,
there is further movement traverses to the bottom dead center (as a rule, it
is possible to adjust / programming), reaching the bottom dead center occurs
extract under pressure.
This is the time required for distribution to the entire length of the
workpiece, because this factor affects the quality of manufactured products.
After the end of time, shutter speed, you need to release part of the
effort. To this end, cross-arm rises up to the required size at a slower
speed. This process is called decomp
ression. After the end of decomp
yoke reaches the top dead center. The machine will come in motion after
another pushing the pedal or button two-handed control.
