power presses
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 presses3
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
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

THIRTY-EIGHT STEPS THAT CAN SAVE YOUR FINGERS, HANDS OR YOUR LIFE

Safety is everyone’s responsibility !

the work area
THE WORK AREA
  • Can the metal be moved into the work area, still leaving enough room to get out ?
the work area7
THE WORK AREA
  • What is the condition of the floor? Does it need repair? Report it!
press integrity
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-offhose or die block
press integrity9
PRESS INTEGRITY
  • Are all the bolts tight?
  • Are there any visible cracks?
press integrity10
PRESS INTEGRITY
  • Are all the service lines (electrical, air, etc.) Properly connected and free of any damage. Report any deficiencies to your supervisor.
press integrity11
PRESS INTEGRITY
  • Have I tested the clutch and brake operation before starting the main motor? Immediately after?
press integrity12
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 integrity13
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 integrity14
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 integrity15
PRESS INTEGRITY
  • Is all of the auxiliary equipment (roll feed, scrap chopper, blow off, etc.) In good working order?
press adjustments
PRESS ADJUSTMENTS
  • Have I checked all the knockout adjustments?
press safeguarding
Does the guard or device positively prevent body access into the danger zone?

PRESS SAFEGUARDING
press safeguarding18
PRESS SAFEGUARDING
  • Are the sides and back of the press guarded or placed in such a way that another person cannot be injured by any part of the machine?
press safeguarding19
PRESS SAFEGUARDING
  • Is the safety guard sturdy and secure? Does the safety device work properly?
press safeguarding20
PRESS SAFEGUARDING
  • If I have a foot pedal, is it guarded on the top and sides?
  • Does it spring back when released?
the point of operation
THE POINT-OF-OPERATION
  • Is the die area clean? Have all slugs and debris been removed?
the point of operation22
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
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 !

understanding risks24
UNDERSTANDING RISKS
  • Do I know the “tonnage” of the press and the requirement of the tooling? Do I know if the press is overloaded?
understanding risks25
UNDERSTANDING RISKS
  • Do I understand the maximum thickness or “gauge” and type of metal which the tooling and press can safely run?
press in operation
PRESS IN OPERATION
  • Does the machine operate smoothly and sound O.K.?
  • Any squealing? Shuttering? Clicking? Clanking? Excess vibration?
press in operation27
PRESS IN OPERATION
  • Does the die stripper work properly?
press in operation28
PRESS IN OPERATION
  • Does the take-up reel work properly?
press in operation29
PRESS IN OPERATION
  • In operation, does the die bind or jam? If so, notify your supervisor. The problem may be the tooling, the press, or the stock/part.
press in operation30
PRESS IN OPERATION
  • Does the clutch/brake work properly. In the case of a full revolution press, does the drag brake stop the press at top center?
understanding risks31
UNDERSTANDING RISKS
  • What is the expected Noise Level? Do I need hearing protection?
