7.11 OPTIONAL PUNCH AND DIE HOLDERS
7.11A 2-1/2" AND 3" DIE INSERTS
The 2-1/2 and 3 inch (63 and 76mm) die inserts are designed to fit in the standard die holder in place of
the 2 inch (50mm) insert. They are used in oversize punching applications. For applications, refer to the
punch and die section of the Tooling Parts Manual.
7.11B OFFSET DIE HOLDER FOR FLANGE PUNCHING
The offset die holder is used for punching holes in the flange of structural shapes such as channel,
I- beam and H-beam. The offset die holder is installed in place of the standard die holder. The offset die
holder requires four bolts to anchor it to the bolster. Use the two bolts provided with the die holder and
the two bolts from the standard die holder on the machine. Use the same method of installing and
aligning punches and dies as outlined in SECTION 6.1, with a few exceptions. The die holder must be
removed to install a new punch and die. The down-stroke of the machine must be set.
CAUTION: Failure to set the stroke will allow the punch retaining nut to strike the die holder,
causing damage to the machine and possible injury to the operator. Because of its design, the offset
die holder has a maximum capacity of 30 tons. Exceeding 30 tons will damage the tool and may
cause injury to the operator. For punch tonnage requirements, REFER TO FIGURE 9 ON PAGE
26.
The offset die holder is designed to be used in conjunction with an offset stripper. The standard stripper
will not work with the offset die holder.
7.11C 6 X 6 DIE HOLDER
Always follow the preferred method of aligning punches and dies. SEE SECTION 6.1. The 6 x 6 die
holder is installed in place of the standard die holder. The 6 x 6 die holder requires four mounting bolts
that are shipped with the tool. Capacities for oversize punching with this tool go up to 4 inch (100mm)
diameter rounds. For sizes and applications, refer to the punch and die section of the Tooling Parts
Manual.
7.11D #45 PUNCH RETAINING NUT
The #45 punch retaining nut is of the same design as the #40 and is used in oversize punching
applications. For applications, refer to the punch and die section of the Tooling Parts Manual.
