Positive Stop System
The Positive Stop System provides an easily adjustable method of precisely maintaining the
stopping point of the machine cylinder. The system is particularly well suited for improving uniformity
on soft delicate work pieces. It is also effective when inserting small hardware.
In addition to aluminum, the system also provide excellent insertion results on a wide variety of
softer materials such as fiberglass printed circuit boards and many plastic or composite materials.
When using this system, the machine is set up to exert a Force/Pressure which is about 20%
above the normal insertion force specified by the manufacturer of the hardware. The accurate stopping
point of the machine’s stroke is controlled by a precision machined nut in the Nut Tube, and screwed on
to a threaded rod extending up from the top of the machine’s cylinder. When the nut contacts the Stop
Tube, the machine exerts the insertion Force/Pressure on the Nut Tube, not the hardware or workpiece.
The machine then reverses and returns to the setup Travel position in the same manner as any other
stroke.
During the Setup Procedure, the machine’s Force on the Control Panel
must be set to a force of 500 pounds (2200N) higher than the force
the manufacturer recommends to insert the hardware.
The Nut Tub is pinned to the Stop Tube so that the stopping point can be adjusted by rotating the
Tube Assembly, that is, either the Nut Tube or the Stop Tube.
1. Turning the Tube Assembly counter-clockwise positions the Nut Tube lower (this shortens the
machine’s stroke.)
2. Turning the Tube Assembly clockwise positions the Nut Tube higher (this lengthens the
machine’s stroke.)
The pitch of the thread on the Threaded Shaft is 14 threads per inch (25.4mm).
1. One complete revolution of the Tube Assembly will increase of decrease the machine’s stroke by
0.07 inches (1.8mm.)
2. The stroke of the machine can be adjusted from 0.375 inches (10mm) to 8.5 inches (216mm.)
with this range the Positive Stop System can be used with all Haeger Tooling Setups, including
the J-Frame.
The Lock Knob on the right side is used to lock the Tube Assembly in position once they have been
properly set.
1. Turning the Lock Knob clockwise will lock the Tube Assembly.
2. Turning the Lock Knob counter-clockwise will unlock the Tube Assembly.
