9.4 Rod Shear Operation
Rod Shear will provide distortion and burr free cuts
to mild steel rod and square bar stock as listed in the
Ironworker specification.
The Rod Shearing blades have 6 round and 1
square shearing cavities built into the rocker arm
and frame as a standard station of this ironworker.
The stationary blade is mounted to the vertical frame
plate and the pivoting blade is mounted to the rocker
arm.
Safe Operation
Observe the following guidelines when operating the
Rod Shear.
•
Never exceed the capacities of the machine or
tooling as described in the Ironworker
specifications or listed at the tooling station.
•
Keep the tooling clean.
•
Do not stack cut material.
•
Perform complete shearing operations only –
partial cuts may jam the tooling and could result
in breakage and operator injury.
•
Do not shear more than one rod at a time.
9.4.1 Rod Shear Operation
Referring to Figures 16:
1.
Clear shear station of any tools or debris prior
to powering the machine on.
2.
Turn machine on.
3.
Press the foot pedal to retract the cylinder to
open the rod cavities.
4.
Mark the material for the length needed.
Example: 10” length wanted. Marked at 13.00”
for alignment.
Figure 16
5.
Place rod stock into the tooling guard and
position your cut mark adjacent to the front
surface of the tooling guard. (Fig. 16, A)
6.
Use one or two drops of SAE#30 oil between
the shear blades to extend the life of the blades.
7.
Hold the workpiece firmly, keeping your hands
a safe distance away from the working area. Do
not stand directly behind the workpiece during
the shearing operation, but off to one side.
Once safely positioned, use your foot to press
and hold the cylinder extend pedal. Maintain
pressure until the workpiece has been sheared.
8.
When the cut is complete, release the extend
foot pedal and press the retract foot pedal to
open the rod shear station for the next cut.
