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 neutral automatically.

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

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 other.

Table 7-5 shows the bars that may be bent by the Ironmaster and the number of bars it will bend in one operation.

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 SUPPORT.

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 up.

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.
