with the end of the rebar protruding a sufficient distance
for the cleat slide to be upright to engage it where you
want the bend to commence.
2. Move the cleat slide to contact the rebar and
tighten the locking screws.
3. Move the positioner slide bar until the roller
contacts the rebar and tightens the T handle.
4. Set the desired angle of bend on the graduated
control rod which is under the right side of the working
table. This is done by placing the trigger pin of the rear
adjustable stop (toward the rear of the machine) in the
hole corresponding to the angle of bend, in this case,
180 degrees. This rod is graduated from 5 degrees to
190 degrees at 5-degree intervals.
NOTE: ENSURE THE FRONT ADJUSTABLE
STOP TRIGGER PIN IS IN THE O HOLE, so the
turntable will return to and stop in the START position
when retracted after the bend.
5. Advance the engine throttle to operating speed,
and move either the rear bending control lever or slide
bending control lever to the bend position. This actuates
the bend cylinder. The lever will stay in the bending
position until the bend is completed, the rack movement
disengaging the cylinder, and the levers returning to
6. To remove the rebar from the machine after the
bend is completed, apply light intermittent reverse
pressure to the lever until the bar releases from the
radius roll. After removal of the hook from the machine,
move the lever to the position shown on retract to
return the turntable to the START position.
Multiple bending is accomplished the same way
as standard hook bending for bars up to No. 8 simply
by placing the bars in the machine one on top of the
Table 7-5 shows the bars that may be bent by the
Ironmaster and the number of bars it will bend in one
On the side of the machine next to the shear is the
shearing support (fig. 7-16). This support holds the
bars square between the shear blades and prevents
them from kicking up during shearing. The upper
jaw of the shearing support is adjustable. For bars
three-fourths inch and smaller, place this jaw in the
LOWER position. For larger bars, use the UPPER
position. NEVER SHEAR WITHOUT USING THIS
To operate, insert the bar to be cut to the farthest
point possible toward the inside of the blades (fig.
7-15), making sure that the blades are in the fully
OPEN or RETRACT position. With light downward
pressure on the shear control lever, hold the bar in this
position until the shear grips. Continue applying
pressure downward to the full limit of the lever until
the bar is sheared To retract the shear, pull the lever
The same-size bar that can be bent can be sheared
Multiple shearing, however, can be accomplished only
on bars of less than 0.44-square-inch area. When
shearing more than one bar at a time, always place the
bars side by side in the shear, as shearing with bars
piled on top of each other may cause blade failure.
