Basic Bending
Bending operations require the fingers to be parallel with
the edge of the clamping block and require the setback
and clamping pressure to be correctly adjusted for the
thickness of the workpiece.
To perform a basic bending operation, do these steps:
1.
Lift the clamping handle to open the clamping leaf
all the way.
2.
Insert the workpiece between the fingers and the
clamping block.
3.
Align the fingers of the clamping leaf to the bend
mark on the workpiece, and clamp it in place.
Note
: Do not force the clamping handle. If the han-
dle is hard to put in the locked position, the pres-
sure may need to be adjusted for the sheet metal
thickness. The holding pressure of the clamping
leaf needs to be just tight enough to hold the sheet
metal from moving when bending.
Setting Stop Collar
The stop collar (
Figure 25
) limits the amount that the
bending leaf can travel during bending, thereby allowing
you to repeat a bend at an exact angle.
To use the stop collar, do these steps:
1.
Completely loosen the stop collar.
2.
Make the bend that you want to repeat and hold the
bending leaf in place at the top of the bend.
3.
Slide the stop collar up against the stop hub and
tighten it in place (
Figure 25
).
4.
Check the stop collar by lowering the bending leaf
and then raising the bending leaf into a bend. If the
stop is working correctly, the bending leaf will stop
in the same position as the first bend.
