Power Press
Operator Training
Power Presses…
•
•
•
•
Have a flywheel
Operate by transferring energy from a
rotating flywheel to the ram (or slide) by
means of a clutch
May be a “full-revolution” design, with a
“trip” clutch engagement, or
May be a “part-revolution” design, with a
friction clutch and brake
Power Presses…
•
•
•
Are generally defined in “size” by the
force that they can generate – from
under 5 ton to over 300 ton capacity
Have a variety of forms and styles. The
most common are straight-sided and
open-backed inclinable (OBI) styles.
Are addressed in detail in ANSI B11.1
and OSHA 29 CFR 1910.217
Safe Operation of a Power
Press Depends Upon…
•
•
•
•
•
The structural integrity of the machine
and it’s safeguards
The reliability of the control system
The condition of the tooling and feed
mechanisms, and the work area
Your training and awareness
Strict observance of safe work practice
Thirty-Eight Steps That
Can Save Your Fingers,
Hands or Your Life
Safety is everyone’s
responsibility !
The Work Area
•
Can the metal be moved into the work
area, still leaving enough room to get
out?
The Work Area
•
What is the condition of the floor? Does
it need repair? Report it!
Press Integrity
•
•
Have I checked the press completely
before beginning my shift?
Use your check list! Make sure that
someone has not left something on the
press, such as a turnover bar, blow-off
hose or die block
Press Integrity
•
•
Are all the bolts tight?
Are there any visible cracks?
Press Integrity
•
Are all the service lines (electrical, air,
etc.) properly connected and free of any
damage. Report any deficiencies to
your supervisor.
Press Integrity
•
Have I tested the clutch and brake
operation before starting the main
motor? Immediately after?
Press Integrity
•
Does the press continue to cycle when
the footswitch or palm buttons remain
depressed? If so, it does not have
required “single-stroke capability.”
– Notify your supervisor immediately.
– Not required on presses when used in the
continuous mode.
Press Integrity
•
Does the press cycle with only one palm
button depressed, or with one
continuously held down and the other
depressed to start the cycle?
• If so, it does not have required “anti-tie-
down circuitry.”
• Notify your supervisor immediately.
Press Integrity
•
•
Are the operating controls (mode
selector, palm buttons, foot switch, top
stop, emergency stop) in good working
condition?
Is the “ground” fault detection lamp lit.
• Do not operate the press if light is not.
Press Integrity
•
Is all of the auxiliary equipment (roll
feed, scrap chopper, blow off, etc.) in
good working order?
Press Adjustments
•
Have I checked all the knockout
adjustments?
Press Safeguarding
•
Does the
guard or
device
positively
prevent body
access into
the danger
zone?

guarded or placed in such a way that
another person cannot be injured by
any part of the machine?
Press Safeguarding
•
•
Is the safety guard sturdy and secure?

removed?
The Point-of-Operation
•
Can the parts I feed be placed into the
die easily, without causing damage to
the parts, or any part of my body?
Understanding Risks
• Do I truly understand the safe
operation of the press … or do I need
more training?
– Don’t be afraid to admit it !
– Don’t be afraid to ask “dumb” questions !
Your life could depend on it !
