Most Edwards Ironworkers allow for Oversize Punch tooling to be
installed in either the punch station or the open station. Refer to
Ironworker Accessories speci cations for capacities of oversize
punch tooling.
Setup
Oversize punch tooling includes an oversize punch stripper’ oversize
punch holder assembly, oversized die table or oversized pedestal die
table and an oversized wrench. Punch and dies are wearing parts and will
need to be maintained or replaced over time. Refer to the Maintenance
Manual for removal and replacement instructions. When installiing over-
size punch and die tooling please observe the following steps.
Turn off power to machine by depressing the red stop / off button
or lockout upstream power at the main electrical panel.
Install the oversize punch holder:
1. Oversize punch tooling can be installed in either the punch station
or the opposite, open station end of the Ironworker. Remove exist-
ing tooling or debris from installation site.
2. Install oversize punch block /stem assembly to the moving center
with hardware provided. Tighten assembly to moving center.
3. Insert oversize punch in oversize punch nut and thread onto over-
size punch block /stem assembly. Tighten with wrench provided.
If using a shaped punch, align the locating keystock of the punch
with the corresponding slot within the punch stem assembly and
tighten the punch nut with the wrench.
Install the oversize pedestal die table:
1. Clear the Ironworker base table of any debris.
2. Install the oversize die table with the die opening facing away
from the Ironworker. Align the slotted holes of the die table with
the base table holes and insert hardware provided.
3. With die table hardware loosely installed, insert die into die holder
and secure with set screw.
4. Turn Ironworker on and inch down the punch to meet the die with
the foot pedal jog control. Check to see that the punch is centered
within the die.
5. Once punch is aligned with die, turn off power to machine; secure
the die table to the Ironworker base table by tightening the hard-
ware provided.
6. Install the oversize punch stripper assembly to the Ironworker
frame with the hardware provided.
7. Swing the stripper bar into place allowing for minimal clearance
between the top of the material to be punched and the bottom of
the stripper and tighten the stripper bar bolts.
Safe Operation
Observe the following guidelines when operating the Oversize Punch
tooling.
• Follow manufacturers punch and die clearance and tonnage
recommendations as shown (Figure1, Punch Operation) in this
manual.
• Never exceed the capacities of the machine or tooling as de-
scribed in the speci cations or listed at the tooling station.
• The thickness of the material you are punching should not exceed
the diameter of the punch being used.
• Check punch and die alignment after every tooling change.
• Adjust the punch stripper supplied with your Edwards Ironworker
to allow for material positioning and material stripping.
• Do not stack material to punch in the punching station.
• Use 1 - 2 drops of oil at the punch to aid in stripping material
from the punch as well as to extend the life of the punch tooling.
• Punch complete holes only – partial holes will side load the punch
tooling and could result in punch breakage and operator injury.
• Use punch aids when working small items at the punch station.
Oversize Punch Tooling Operation
1. Clear the punch station of any tools or debris prior to powering the
machine on.
2. Place the material to be punched between the punch and die.
Check to see that your material is spanning the stripper plate and
that adequate material is avaiable to safely position the material.
3. Clear your hands from the working area and press the foot pedal to
move the punch through the material and into the die.
4. When the punch is complete, release the foot pedal to automati-
cally strip the material from the punch and return the punch to its
neutral position.
