6.3 TOOLING ARM ADJUSTMENT
For parts identification, SEE FIGURE 15 ON THE FOLLOWING PAGE.
Adjustment of the tooling arm is maintained by a pressure plate at the pivot point, two rub plates
backing up the arm and the two rub plates at the notcher station.
CAUTION: BEFORE MAKING ANY ADJUSTMENTS ON THE TOOLING ARM, THE BAR
SHEAR BLADES, ANGLE SHEAR BLADES AND ROD SHEAR BLADES MUST BE BACKED
OFF TO PREVENT DAMAGE TO THE BLADES. THE LOWER NOTCHER BLADES MUST
BE REMOVED TO PREVENT POSSIBLE INJURY TO THE OPERATOR AND DAMAGE TO
THE BLADES. AFTER THE TOOLING ARM HAS BEEN ADJUSTED, THE BLADES FOR
EACH TOOL SHOULD BE READJUSTED FOLLOWING THE INSTRUCTIONS FOR EACH
RESPECTIVE TOOL.
1.
After backing off or removing all of the tooling blades, the tooling arm back-up rub plates (H) and
the notcher rub plates (P) should be backed off and checked for wear. If the rub plates are worn,
they should be rotated or replaced. DO NOT adjust the rub plates back up to the arm yet.
2.
First, adjust the pressure plate (I) at the pivot point. This is adjusted by loosening the locking nuts
(S) on the adjustment screws (R). Tighten the screws in a diagonal order. Adjust the screws up
snug. DO NOT OVER-TIGHTEN; it will just cause excessive wear.
3.
Adjust the rub plates (P) on the notcher, adjusting one side up until the rub plates make contact.
Then, adjust the other side up the same way. Tighten the locking bolts (O).
4.
Adjust the two tooling arm rub plates (H).
NOTE: TO GAIN VISUAL ACCESS, IT MAY BE NECESSARY TO REMOVE THE
CYLINDER SHROUD AND THE DROP-OFF COVER ON THE BAR SHEAR.
5.
Place the selector switch in the START position and the run/jog switch in the JOG position.
Power the machine. Place the selector switch in the SHEAR position. Jog the tooling arm to a
point where the rub plates will meet in the center position. Adjust the center adjustment screws
(N) in until the rub plates contact each other. Then, adjust the rest of the adjustment screws until
they contact the rub plate.
6.
Tighten the mounting bolts (O) in the rub plates (H).
7.
The tooling arm is now adjusted and the blades on each respective tool can be readjusted
following the instructions in their respective sections.
