rial. If the workpiece whips-down, use the
clamp/stop feature of the machine control so
your hands can be removed from the workpiece
when the bend is made. Set the forming speed
to avoid excessive part “whip”.
12. When you leave the machine, place the ram at
the bottom of the stroke or place safety blocks in
position under the ram. Turn OPERATOR CON-
TROL selector to “OFF” and remove the key,
even if you will be away for only a few minutes.
13. Have the routine scheduled maintenance and
adjustments performed as shown on the Main-
tenance Checklist in SECTION 9.
14. Check the alignment of the dies before operat-
ing the machine after the dies have been
changed or if the machine has been idle
overnight. Improper alignment could cause
chipping and flying chips can cause lacerations
and eye injuries.
15. Report any cuts, bruises and all other injuries
to your supervisor or the medical department
immediately. They are the best judges of the
seriousness of your injury.
GENERAL GUIDELINES FOR
INSTALLING, REMOVING AND
TRANSFERRING TOOLING (DIES)
Installing, removing and transferring tooling can be
hazardous and should be done with proper super-
vision by experienced set-up men. Improper han-
dling techniques can cause muscle strains, hernias
or serious disabling injuries.
1. Transfer dies using the proper techniques for
the weight of the die(s) being handled:
a. Very light dies, up to 50 pounds (23kg), can
be carried manually or transferred on a die
truck.
b. Dies weighing over 50 pounds (23kg), or
those that are awkward to move, should be
handled by a hoist.
If the punch or die has tapped holes for lifting
attachments, be sure the proper size bolts are
used. A bolt smaller in diameter than the
tapped hole will slip out and cause serious
injury. If no lifting attachments are provided,
use only approved rope slings so the dies will
not be nicked or scratched.
Lift the dies high enough to clear any obstruc-
tions, but no higher.
2. When installing and setting up dies:
a. Clean machine and filler block surfaces to
which the dies will be fastened. Always turn
the machine OFF when working in this area.
b. Inspect the dies for chips, cracks or other
hazardous conditions. Wipe them off with a
clean cloth.
c. Always place the machine control MODE
selector in the “SETUP” position so the ram
can only be moved by the use of palmbuttons
or RAM UP button or softkeys.
d. Never reach into or through the die area
when aligning the dies or setting the gaging.
3. When removing dies from the press brake:
a. Clear the work areas of all stock, containers,
tools and other equipment.
b. After placing safety blocks between the dies
and turning OFF the machine, clean both
upper and lower dies using a bench brush
and finally wipe clean with a cloth.
c. Place machine control MODE selector in the
“SETUP” position so the ram can only be
moved by use of the palmbuttons or RAM UP
button or softkeys.
d. Never loosen the ram clamp bolts or select
“UNCLAMPED” on the optional Power
Clamp control unless the dies are in a
closed position and the OPERATOR CON-
TROL selector is in the “OFF” position.
Detailed step-by-step instructions for installing and
removing tooling are provided in the SET-UP AND
USE section of this manual. These instructions
should be followed for safe installation and removal
of tooling from your CINCINNATI Press Brake.
Also included in the SET-UP AND USE section of
this manual are instructions for making bends,
gaging, blank development and use of the machine
controls.
