Arbor Support
The arbor support is a hinged steel bar that, when attached to the
tooling arbor, rigidly supports the arbor and eliminates a potential can-
tilever tooling failure. THE ARBOR SUPPORT STRUCTURE IS REQUIRED
TO BE ENGAGED IN ALL STANDARD PRESSING OPERATIONS.
Tooling Block
The tooling block of the HP20T is fi xed to the ram of the cylinder.
The machined surface features horizontal T-slots for custom tooling
applications and a vertical slot for standard 6” brake tooling. Tooling
fi xes to the vertical slot with 4 set-screws. The tooling block slides
on two, adjustable gib-pins recessed into the machined surface. The
gib-pins provide leveling and bearing surfaces that will wear over time.
Periodically adjust the gib-pins to ensure the ram is parallel to the table
surface.
Press Operation
• For Operator safety, wear personal protective equipment, clear the
work zone of any tooling or debris prior to powering the machinery on.
• Perform press inspection.
• Perform workpiece inspection.
• Turn power source on.
• Retract ram, install press tooling.
• Adjust tooling as necessary to achieve the shortest ram travel.
• Safely load, position and support workpiece.
• Align and secure tooling to the tooling block.
• Carefully, slowly, extend ram and tooling to meet press site. Preload
the workpiece and observe workpiece support and tooling alignment.
Observe the preloaded condition from multiple angles to assure
that the press tooling is in alignment with the ram and workpiece. If
unstable, reverse ram, reset workpiece and re-align press tooling.
• Gradually build pressure to complete the press operation.
• Retract the ram to relieve hydraulic pressure following the press
operation.
