Your Ironworker includes a notcher as a standard feature. When
maintained within tolerance, the notcher will provide a distortion
and burr free shear cut to mild steel bar, plate or angle iron. Notch-
er 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. Notcher blades are wearing parts
and need to be maintained or replaced over time. Observe the fol-
lowing procedure when maintaining the Ironworker notcher sta-
tion.
Turn off power to machine by depressing the red stop / off
button and lockout upstream power at the main electrical
panel.
Remove and replace moving blade:
1. Remove or swing the notcher guard assembly up and away from
the notcher table.
2. Remove the two 1/2” socket head cap screws that secure the ex-
isting top notcher blade to the moving center.
3. Clean the keyway in the moving center of any dirt or debris.
4. Install the top notcher blade with the keyway up. Secure the top
blade using the two 1/2” socket head cap screws. Tighten bolts.
Remove and replace stationary blades:
1 The notcher table includes three blades secured within the table
housing. Remove the four 1/2” bolts and washers that secure
notcher table to the base table.
2. Remove the six, 3/8” socket head cap screws that secure the
blades into the base table housing.
3. Clean the blade pockets of any dirt or debris.
4. The bottom shear blades have multiple cutting surfaces. Either ro-
tate/ip the existing blade set to the new cutting surfaces or install
new cutting blades into the blade pockets. Re-install the six 3/8”
socket head cap screws and tighten. The blades should be planar
to eachother at the top surface of the working table.
5. Re-install the notcher table with the open “U” facing the center of
the machine. The guide foot of the top notcher blade should be
centered within the base table blades.
4. Loosely secure the notcher table from the underside of the base
with four 1/2” bolts and washers (provided).
5. Check for top and bottom blade alignment by powering up the ma-
chine and slowly inching down the top blade to meet the bottom
blades with the foot pedal. Power the machine off.
6. 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.
7. 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.
8. Adjust the cap screws at the end of the notcher table to engage
the base notcher table to the base table. Lock the two 3/8” nuts in
place to secure the cap screws in place.
9. Swing the notcher guard back in place.
Notcher 50/60/65/75/100dx/120 Ton Ironworkers
Your Ironworker includes a standard or oversized pedestal punch
and die assembly installed within the punch station. When worn
or chipped, the punch and die must be replaced. Observe the fol-
lowing procedure when maintaining the Ironworker punch station.
Turn off power to machine by depressing the red stop/off
button and lockout upstream power at the main electrical
panel.
Maintain as follows:
1. Swing the Punch Stripper up or away from the punch by loosening
the stripper assembly bolts.
2. Remove punch by loosening the punch nut assembly with factory
supplied wrench.
3. Remove die by loosening the set screw at the front edge of the
punch table and then lifting die from the die holder. If the die resists
removal gently tap the die from the underside of the punch table to
loosen the die for removal.
4. Install new die and tighten set screw. If loading a shaped die, align
the whistle spot with the set screw and tighten.
5. Install new punch and tighten punch nut with wrench. 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.
6. Check for punch and die alignment by powering up the machine
and inching down the punch to meet the die with the foot pedal.
Check to see that the punch is centered in the die.
7. In the event that the punch and die are not aligned, rst conrm
that the punch is seated properly in the punch nut assembly. If not
seated properly, repeat step 5 . If seated properly, loosen the bolts
under the die table allowing the table to be moved to center the die.
When aligned, tighten the table bolts to secure the table and repeat
step 6.
8. Swing the stripper bar back in place allowing for minimal clearance
between the top of the material and the bottom of the stripper and
tighten the stripper bolts.
