of the punch and die at regular intervals
during the work session.
PUNCH STROKE ADJUSTMENT
The travel limits of the punch can be adjusted by
moving two collars (A and B) on the discharge
side of the machine. When punching large
quantities of the same material and hole size,
limiting the travel of the punch will reduce
production time.
Two collars (A and B) set the upward and
downward travel limits of the punching station.
Each collar is locked in place with a socket head
set screw accessible through the slot in the cover.
To adjust the travel of the punch:
1.
Press the punching station's Emergency
Stop pushbutton.
2.
Adjust each collar to achieve the desired
range of punch travel:
Upper Collar (A):
Move down to increase the punch's
upward travel.
Move up to decrease the punch's upward
travel.
Lower Collar (B):
Move up to increase the punch's
downward travel.
Move down to decrease the punch's
downward travel.
Important: When the punch cylinder is at its
upper or lower limit of travel the stroke
adjusting collars must make contact with one
of the limit switches so the hydraulic pump can
"unload", preventing the motor from being
overloaded and the hydraulic fluid from
getting too hot.
PUNCH AND DIE SELECTION
Important: This section provides information
which must be followed for safe, satisfactory
punching operations.
Proper punching requires careful attention to
selecting the proper sized die, proper alignment of
the punch and die, and staying within the
machine's rated capacity.
Avoid serious injury.
Never exceed the machine's
punching capacity.
Punch Size
The punch size equals the desired hole size. For
example, to punch a 1/2" diameter hole you
would use a 1/2" diameter punch.
Important: Do not punch holes smaller than
the thickness of the material. For example,
when punching 1/4" thick material the
smallest hole that can be punched is a 1/4"
diameter hole.
Die Size
The size of the die is determined by the thickness
of the material being punched. The size of the die
must provide clearance between the die and the
punch.
Punching material 15/32" thick or less:
When punching material 15/32" thick or less, add
1/32" to the size of the punch to determine the
proper size die.
Example #1 - Round holes: When punching a 1/2"
diameter hole in 3/8" thick material, you would
use a 17/32" diameter die.
