Your Edwards Ironworker may include a 241 punch and die as-
sembly installed within the punch station. When worn or chipped,
the punch and die must be replaced. Observe the following proce-
dure 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 clear-
ance between the top of the material and the bottom of the strip-
per and tighten the stripper bolts.
