Product Manual B

• Safe Use of Tooling Edwards Manufacturing Company provides
optional press tooling designed to provide for basic Press ap-
plications. These tools are not designed to provide for all Press
applications. Care must be taken when selecting Press tooling.
Select tooling that is designed and rated for the specic applica-
tion. Press with the shortest, most compact, tool length available.
Conrm that Press tooling and workpiece are aligned and follows
a direct press path. Conrm that the correct Press sleeve and ar-
bor plate are used. Misaligned loads may fail the Press tooling or
workpiece and cause operator injury or damage to the machinery.
• Special Fits Not all parts were designed or engineered to be
removed or applied with a press. When inspecting your workpiece,
conrm any press tolerances, environmental, heating, cooling or
xative requirements that require special care prior to initiat-
ing the press operation. Do not proceed with a Press operation
without acknowledgment that the workpiece is pressable.
• Do Not Force Press Consider the rating of the Press and the
work at hand. Gradually build pressure being applied to the
workpiece. Carefully observe the workpiece to avoid tooling
misalignment or workpiece failure. Observe the Press as it reacts
under load. Do not overload the Press. Under heavy press opera-
tion built up force is released when the pressed part breaks free
of its mount. This release of pressure is sudden and can appear
to shake the machinery. Take care to avoid parts falling from the
workpiece.
Press Operation
1. For Operator safety, wear personal protective equipment, clear
the work zone of any tooling or debris prior to powering the
machinery on.
2. Perform Press inspection.
3. Perform workpiece inspection.
4. Turn power source on.
5. Retract ram, install press tooling.
6. Adjust Press bed as necessary to achieve the shortest distance
between the press pin and workpiece. Conrm hardened pins are
fully engaged with linchpins secured.
7. Tighten retention bolts.
8. Safely load, position and support workpiece in press cavity.
9. Align and secure cylinder and ram over workpiece press site.
10. Conrm minimum table height to workpiece, alignment of ram
and tooling to workpiece.
11. Carefully, slowly, extend ram and tooling to meet press site.
Preload the workpiece and observe workpiece support and tooling
alignment. Observe the preloaded condition from multiple angles
to assure that the Press tooling is in alignment with the ram and
workpiece. If unstable, reverse ram, reset workpiece and re-align
Press tooling.
12. Gradually build pressure to complete the Press operation. Do not
overload the Press.
13. Retract the ram to relieve hydraulic pressure following the Press
operation.

Edwards Manufacturing Company provides optional press tooling
designed to provide for basic press applications.
The Press Brake Tooling Set includes:
• 1 ea. 3” dia. x 3 1/2” V-Cup
• 1 ea. 3” dia. x 3 1/2” Threaded Cup
• 1 ea. 2” dia. x 4” Threaded Shaft
• 1 ea. 1 1/2” dia. x 4” Threaded Shaft
• 1 ea. 1” dia. x 4” Threaded Shaft
• 1 ea. 1” dia. x 4” Tapered Shaft
These tools are not designed to provide for all press applications.
Choose your tooling according to the Operations section of this manual.
Press operations are dangerous and require extreme care and
caution in the preparation of the material being worked, the press
set-up and the pressing operation. Please refer to the following
setup, safe operation and press operation sections for an understand-
ing of potential hazards present in any pressing operation.
Setup
Turn off power to press by depressing the red stop / off button
on the Edwards Ironworker or Edwards Porta-Power or lockout
upstream power at the main electrical panel.
Your Shop Press was shipped with a standard press cup. A press
cup protects the ram end of the cylinder during pressing operations.
NEVER PRESS DIRECTLY WITH CYLINDER RAM END. PRESSING
WITH EXPOSED RAM END MAY DAMAGE THE MACHINED SUR-
FACE, SCRATCH THE RAM AND DAMAGE THE CYLINDER AND VOID
THE MANUFACTURER’S WARRANTY.
Remove the standard press cup by relieving the ball-detent screws
in the cup face. If utilizing the V – Cup press end, install by slipping
the cup end over the ram end of the cylinder. Tighten the ball-detent
screws in the V-Cup so that the cup fully engages the machined groove
in the cylinder ram.
If utilizing the threaded or tapered shaft press tooling, note that this
tooling threads into the 3” dia. x 3-1/2” Threaded Cup. Install threaded
shaft ends into threaded cup and tighten so that the tooling is secure
during the press operation. Once the threaded cup and threaded shaft
are secure, install by slipping the cup end over the ram end of the
cylinder. Tighten the ball-detent screws in the threaded-cup so that the
cup fully engages the machined groove in the ram end of the cylinder.
Safe Operation
Observe the following guidelines when performing Press operations.
• Operator Safety / Safe Work Zone Applying pressure to parts
or assemblies can fail the part being worked, fail a part adjacent
to the work or fail the pressing tool. Failed parts can become
airborne projectiles with deadly force. Protect yourself with
appropriate personal protective equipment when operating the
press. Protect others by dening a safe work zone for press use
and limiting access to the press operator.
• Press Inspection Press operations may generate concussive
failure to mechanical parts. Although Edwards press machinery is
fabricated with both bolted and welded construction, concussive
failure is a possibility over time or with extreme use. Prior to any
Press operation, visually check all bolted and welded connections
for failure. All bolts must be tight and welds intact. Failure to
verify the structural integrity of the machinery may result in work-
piece shift, part ejection, operator injury or machinery damage.
• Workpiece Inspection Workpiece failure is the most common
source of injury during press operations. Take time to thoroughly
understand the workpiece. Never apply pressure to unstable
objects, round shapes, balls, springs or any item with elastic,
spring-back tendencies. Conrm the material properties of the
workpiece will withstand the pressure to be exerted by the Press.
Conrm that workpiece items are stripped down to their simplest
form. Many components contain unseen items that could fail dur-
ing the press operation. Remove all sub-components known to
the workpiece prior to a pressing operation. Workpiece must be
clean and free of substances at the pressing surface that would
allow the pressing surfaces to slip under load.
• Workpiece Support Workpiece failure may be a result of
improper or inadequate workpiece support. Adequate support
for the workpiece must be present through the entirety of the
Press operation. Understand your workpiece and conrm that the
workpiece support system you employ will withstand the pressure
being exerted through the Press operation.
