12.
Align the punch to the die so that there is equal clearance on all sides of the punch in the die.
13.
Insert and tighten both the die holder bolts (G) firmly.
14.
Check to be sure that the punch and die are still in alignment. Realign, if necessary.
15.
Replace the stripper (B).
NOTE: If punching holes larger than 1", remove the stripper plate or, it will be damaged.
16.
Check to make sure that there are no objects (such as tools) on or under any of the moving parts
of the machine.
17.
Turn the machine on.
18.
Lubricate the punch and die before using and every 5 to 10 holes, thereafter.
FOR LUBRICATION INSTRUCTIONS, SEE SECTION 5.1.
¼
CAUTION: REMOVE THE PUNCH AND DIE WHEN IT IS NOT IN USE.
B.
CHECK PUNCHING TOOLS FOR TIGHTNESS.
Periodically during the day, check the punch and die for alignment. To do this, run the punch
down until it enters the die and turn the machine’s power OFF. Tighten the set screw holding the
die, the die holder bolts and the punch retaining nut. Check the alignment of the punch and die.
Power the machine and jog the punch up and down several times, to be sure of proper alignment.
C.
CONTACT BOTH SIDES OF THE STRIPPER.
Punch holes with sufficient material to contact both sides of the punch stripper. If the workpiece
does not contact both sides of the stripper, the side thrust may break the punch and will deform
the workpiece.
D.
SPECIAL STRIPPERS MAY BE REQUIRED FOR CERTAIN JOBS.
The standard stripper has been designed to work for most applications. For other applications,
such as stripping small channel, a special stripper may have to be fabricated. The important
consideration is to keep material level while stripping. When punching thin strap iron, the
material will tend to draw up into the stripper. To prevent this, a plate or large washer can be
attached to the bottom of the stripper, to reduce the size of the opening. This type of stripper will
also allow you to punch in the corners of material. There is an oversize stripper available for
oversize punching applications.
E.
PUNCHING ANGLE IRON.
This machine is designed to punch angle iron with the leg down. If the application requires
punching closer to the web than the standard dies allow, special offset dies are available.
