Optional Notcher tooling will provide a distortion and burr free,
three-sided shear cut to mild steel bar, plate, or angle stock as list-
ed in the Ironworker Specications as well as the capacity labels
positioned adjacent to the Notching Station. The optional Notcher
tooling for an Edwards Ironworker allows for shaped, straight or
angled notch cutting applications.
Setup
Optional tooling and accessories t within the open station of the
machine. Optional Notcher tooling is equipped with one, three-sided
top notcher blade and three, four-sided bottom blades. The top blade
is mounted to the moving “center” of the Ironworker, while the bottom
three blades are secured into a base housing. If ordered as a factory
installed option, your notcher assembly is setup for immediate operation.
If ordered as an option, the open cavity of the machine must be cleared
of any existing tooling, material or debris prior to tooling installation.
Notcher blades are wearing parts and will need to be maintained or
replaced over time. Refer to the Maintenance Manual for blade main-
tenance, removal and replacement. To setup your Notching Station,
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 top notcher blade:
1. Swing the notcher guard assembly up and away from the notcher
table.
2. Install the top notcher blade with the keyway up and the “foot” of
the blade facing the center of the machine. Secure the top blade
using the two 3/8” socket head cap screws. Tighten bolts.
Install the notcher table:
1. Install the notcher table assembly to the base table. The notcher
table includes three blades secured within the table housing.
Install with the open “U” facing the center of the machine. The
guide foot of the top blade should be centered within the base
table blades.
2. Loosely secure the table from the underside of the base with four
bolts and washers (provided).
3. Check for top and bottom blade alignment by powering up the
machine and slowly inching down the top blade to meet the bot-
tom blades with the foot pedal. Power the machine off.
4. Using a feeler gauge, adjust the clearance between the perimeter
of the top and bottom blades to allow for .010 clearance on all
three sides.
5. In the event that the top and bottom blades are not aligned,
simply loosen the bolts under the table allowing the table to be
moved to center the top blade within the bottom blades. When
aligned, tighten the table bolts to secure the table.
6. Adjust the four set screws at the sides of the notcher table to
engage the base notcher table to the base table. Lock the four
3/8” nuts in place to secure the set screws in place. These added
xtures are to provide additional support to the base table during
the notching operation.
7. Swing the notcher guard back in place.
Safe Operation
Observe the following guidelines when operating the Notcher Station.
• Never exceed the capacities of the machine or tooling as
described in the Ironworker specications or listed at the tooling
station.
• Check notcher blade clearance at every tooling change or
extended notcher operation. Maintain .010 clearance between top
and bottom notcher blades at all times. Failure to maintain clear-
ance will damage blades and support pockets.
• Cut with a minimum two of three sides of the blade surfaces en-
gaging the material being notched. Cutting on one blade surface
may overload the blades and result in tooling damage or injury to
the Operator. See Figures A,B,C.
• Do not stack material to cut in the notcher station.
• Perform complete notch operations only – partial notch cuts may
jam the drop off side of the tooling and could result in breakage
and operator injury.
• Use notching aids when working with small items at the notcher
station.
Optional Tooling - Notcher 25/40/55/100 Ton Ironworkers
Notcher Operation
1. Clear the feed table of the notcher station of any tools or debris
prior to powering the machine on.
2. Turn machine on. The top notcher blade will be in the neutral posi-
tion. Push the material under the tooling guard and into the blade
area. Position your material to the desired cut.
3. Clear your hands from the working area and depress the foot pedal
to activate the notcher station. When the cut is complete, release
the foot pedal to automatically return the top notcher blade to the
neutral position.
