7.5B CHANNEL SHEAR OPERATION
The following are basic steps in shearing with the Channel Shear.
A.
ADJUST BOTH MOVING AND STATIONARY SIDE BLADES TO THE SIZE OF CHANNEL
BEING SHEARED.
Improper adjustment of the vertical blades will result in damage to the Channel Shear. To keep the
channel centered in the unit, it is necessary to reset the stationary side blades for each size of channel.
ONE METHOD OF ACCOMPLISHING THIS ADJUSTMENT IS AS FOLLOWS:
1.
Place a piece of channel, the size to be sheared, in the tool.
2.
Place the selector switch in the START position and the run/jog switch in the JOG position. Power
the machine and place the selector switch in the PUNCH position.
3.
Jog the upper blade down to a point just above the channel and turn the power to the machine
off. Locate the channel so that the upper blade contacts both legs, which will center it in the tool.
4.
Adjust the movable vertical blades up to the flange of the channel. Loosen the fixed vertical blade
clamps (four places) and slide the fixed blades up to the channel flange.
5.
Tighten the blade clamps and adjust the back-up socket set screws up against the fixed vertical
blades.
6.
Check to see that the blades have good alignment, front and back, and have maintained their
perpendicular position to the lower blades.
B.
POSITION THE ADJUSTING HANDLE.
The adjusting handle can be relocated to permit easy opening and closing of the movable vertical blades.
(Approximately 1/2 turn will lock and unlock the workpiece.)
C.
SET THE BOTTOM OF THE STROKE AS LOW AS POSSIBLE.
The bottom of the stroke should be set as low as possible, without bottoming any part of the upper blade,
blade holder or pressure block.
D.
PROCEDURE FOR SHEARING:
Lubricate the blades with oil before making the first cut and every 10 to 15 cuts, thereafter.
This lubrication is critical on the channel shear.
