7.1 6 X 6 ANGLE SHEAR
The 6 x 6 angle shear is a component tool designed to shear angle iron. It installs in the tool station on
this machine and has a maximum capacity of 6 x 6 x 1/2 inch (152 x 152 x 12mm) mild steel angle iron.
The selector switch must be in the TOOL position and the upper arm in the UP position to operate this
tool.
7.1A 6 X 6 ANGLE SHEAR INSTALLATION
SEE FIGURE 19 ON THE NEXT PAGE.
THE 6 X 6 ANGLE SHEAR MOUNTS IN THE TOOL STATION UNDER THE UPPER ARM.
1.
Before mounting the tool under the arm, remove the upper blade and install the
return springs (1).
2.
The selector switch must be in the TOOL position and the arm in the UP position to
operate this tool.
3.
Slide the tool under the arm and as close to the machine’s frame as possible.
4.
The tool is held in place with the finger clamps (2) provided.
5.
Care must be taken to align the slug slot in the angle shear with the slot in the tool table and the
pressure block assembly squarely under the arm.
6.
The upper stroke of the machine should be set so that the upper blade raises high enough to slide
the workpiece freely through the unit. The lower stroke should be set so that the upper blade point
enters the lower blades approximately 1/8 inch (3mm).
7.1B 6 X 6 ANGLE SHEAR OPERATION
Oil must be applied to the blades before the first cut is made and every 10 to 15 cuts, thereafter. Grease
the slider block between the tool and the arm every two hours of operation. A set of lower blade shims
are shipped with each unit. These are to be installed between the lower blades and the side plate when
shearing lighter angle (up to 5/16" or 8mm thick). If a burr develops when shearing very light
gauge angle, the clearance should be reduced further by adding additional shim stock. All shims must be
removed when shearing angle thicker than 5/16 of an inch (8mm).
When cutting angle iron with legs of unequal length, a special upper angle shear blade is necessary.
Do NOT attempt to cut unequal leg angle iron with the standard blade. It only takes one cut to damage
the tool. We have (4) optional top blades available for cutting unequal length angle iron that will
accommodate most sizes. We also have a P/N 026708 "Quick Change" kit available that is a real time
saver. With this kit changing from a standard to an unequal length blade can be done much faster.
