G0646/G0647 50/65 Ton Ironworker
4. Rotate the support frame handwheel to align
the angle iron opening in the frame with the
opening in the dies, then re-tighten the lock
knobs.
5. Thread the appropriate hold-down screw up,
then feed the workpiece through the front of
the support frame and beyond the dies (see
Figure 40).

6. Tighten the hold-down screw close enough
to the workpiece so that it will not move up
during the shearing operation.
7. Set the controls to Notch and Normal, then
use the foot actuator to perform the shearing
operation.
Note: Make sure the cut piece falls through
the rear exit panel and away from the dies so
that it does not interfere with the next opera
-
tion.
Making a Less Than 90° Cut
Follow the same steps for making a 90° cut in
angle iron except position the workpiece at an
angle to the dies. To accomplish this, insert the
workpiece and move the support frame until the
workpiece reaches the desired angle, as shown in
Figure 41, then tighten the hold-down screw.

3. Loosen the three lock knobs of the shearing
support frame (see
Figure 39).
Note: To make an inner angled cut, use the bot
-
tom angle opening (see Figure 41). Conversely,
to make an outer angled cut, use the upper angle
opening.
