Roper Whitney 134, Operation, Parts & Maintenance Manual

Page: 5 / 18

PANEL CONTROLS:
ON/OFF ----- These two buttons, located on the main control panel on the right side of the machine, turn the
hydraulic power unit on and off.
JOG/RUN --- This switch selects either of two running modes. The RUN position is for automatic, single
stroke operation. In this position, the foot switch must be released to repeat the cycle. The JOG
position permits the operator to inch the ram down for alignment and center spotting. In the JOG
position, the ram will continue downward until the foot switch is released. At the bottom-of-
stroke of the machine (set at the factory), the ram automatically returns to the top-of-stroke
position.
JOG UP ----- This button, located on the right side of the machine in the top shroud, will raise the ram from any
intermediate position. The ram will continue to rise until the button is released or the machine
reaches its absolute top-of-stroke position. The
JOG UP button overrides both the JOG/RUN
switch and the adjustable top-of-stroke mechanism.
PUNCH TO DIE ALIGNMENT:
Select the desired punch and die. Insert die into die adaptor (if needed) and tighten screw. Place die
adaptor (or die) in die shoe and tighten square head set screw. Leave die shoe bolts loose. Insert punch
into punch holder and tighten set screw (it may be necessary to move the die shoe for adequate
clearance). Set the selector switch on the main control panel to
JOG , turn the machine on, and inch the
punch toward the die. Adjust the loose die shoe so the punch can enter without striking the die. There
should be equal clearance around the punch for proper punching action. If the ram reaches the bottom-
of-stroke position before the punch can enter the die, remove wear plates from the top of the ram lever
and replace them below. This will lower the ram so the punch can enter the die. When the punch and die
are properly aligned, tighten the die shoe bolts. Recheck alignment after tightening. Adjust wearplates
so at the bottom-of-stroke the punch enters the die between 1/16 and 1/32 of an inch.
TOP-OF-STROKE ADJUSTMENT:
After punch to die alignment is verified, the ram top-of-stroke position must be set. The stroke of the 134
press is infinitely variable between zero and one inch. To set desired stroke length, lower the punch
(using the
JOG setting) to the desired top-of-stroke height. Loosen the two knurled nuts of the trip
mechanism on top of the ram. Run the upper nut up the threaded spindle until it contacts the limit switch
roller. Continue to run the nut up until a distinct click is heard. Turn the nut another quarter turn in the
same direction and lock it in place by turning the lower knurled nut against it. The ram will continue to
stop at this position until the knurled nuts are moved or the wear plates are adjusted.
The ram can be run up to the full one inch stroke position by pressing the JOG UP button. This will
facilitate tool change and part removal. To return to limited stroke operation, depress the foot switch until
the punch enters the die. On returning, the ram will once again stop at the preset height.
