LEVELING SYSTEM (FIGURE
43)
The
leveling
system
of
the
CB
Hydraulic
Press
Brake
consists
of
a
servo
valve
actuated
by
a
leveling
band.
The
leveling
band
passes
over
two
sheaves
on
the
rear
of
the
ram
and
is
anchored
to
the
servo
actuating
mechanism
at
the
left
side
of
the
housing
brace
and
to
the
tilt
adjusting
mechanism
at
the
right
side
of
the
brace.
An
out-of-level
ram
condition
causes
the
leveling
band
to
either
tighten
or
slacken,
which
in
turn
allows
the
servo
valve
spool
to
shift
and
bleed
oil
from
the
top
side
of
the
leveling
cylinder.
Two limit
switches
are-
also
provided
so
an
excessive
out-of-level
condition
will
stop
main
drive
motor.
These
switches
are
set
to
operate
at
a
tilt
of
1/2"
either
direction
in
the
length
between
the
vertical
legs
of
the
leveling
band.
CHECK
THE LEVEL
OF
THE
BED AND RAM:
The
leveling
system
is
designed
to
maintain
the
ram
either
parallel
to
or
at
a
preset
angle
with
respect
to
the
bed
while
cycling.
The
parallelism
of
the
bed
and
ram
is
checked
as
the
ram
passes
.through
the
bottom
of
the
stroke
changing
from
a
downward
to
an
upward
direction.
1.
Set
tilt
control
adjusting
knob
and
pointer
to
their
"zero"
positions.
2.
Adjust
the
speed
control
cams
so
the
ram
approaches
the
bottom
of
the
stroke
in
low
speed
..
3.
Mount a
dial
indicator
on
the
extreme
right
end
of
the
bed
so
it
indicates
the
bottom
reversal
point
of
the
ram.

same
indicator
setting.
5.
Without
changing
the
indicator
or
bottom
stroke
stop
setting)
reposition
the
dial
indicator
at
the
extreme
left
end
of
the
bed.
6.
Run
a
number
of
strokes,
adjusting
the
tilt
control
knob
to
raise
or
lower
the
left
end
of
the
ram,
until
the
indicator
reads
the
same
as
it
