WARNING
Long tubes and rods must be supported in the height-adjustable REMS Herkules,
which is equipped with steel balls allowing easy movement of the pipes in all
directions without tilting the material support. If the REMS Tornado is secured
to a work-bench, then you can also use the bench-mounted REMS Herkules
Y. The capacity of both the REMS Herkules and he REMS Herkules Y is

ie head
The REMS 4" Automatic Die Head progressively opens during the cutting
operation so that it cuts tapered threads only. This continuous opening action
allows perfect tapered threads to be produced with the 4" Automatic Die Head
and drive unit on only light load. A separate set of cutting dies is required for
thread sizes 2½, 3 and 4" in each case.
Chan in die
Retract the chuck until it rests against pressure bolt (10). With he machine
switched off, push in the pressure bolt (10) on the front guide arm (7), and use
the feed lever (8) to move the chuck into its extreme right-hand position. Change
the cutting dies in this position. The dies must be cleaned of all dirt and chips
before inserting them until they are felt to engage. Note the numbering of the
cutting dies(11) and of the die holders (12). Feed in the chuck until the pressure
bolt (10) is free.
WARNING
Before switching on the machine it is vital to ensure that a die are secure,
i.e., check that they do not project from the die head, since his can lead to
collision between the dies and the drive tube causing damage to the 4"Automatic
Die Head.
Settin the th ead en th
On the front guide arm (7) here is a scale ring for each thread size (2½, 3 and
4"). The desired thread size is set by moving the die chuck until the rear edge
of the chuck housing aligns with the appro priate scale ring.
Se uence of ope ation
Push the pipe through the die chuck into the gap between the dies. Using the
thightening wheel (13), clamp the pipe in the self-cen tering chuck slightly. The
rm clamping is automatically done while threading. With the feed handle (8)
– but no cooling lubricant – rst feed in rmly until about 2 turns of thread have
been cut.
Position coolant tube at the side of he cutting head.
After reaching the standard thread length (as per DIN 2999) the die head opens
automatically. Switch off the machine, open the chuck, and remove the pipe.
Makin nipp e and dou e nipp e
The REMS Nippel x (automatic internal clamping) is used to cut nipples. Ensure
that nipples are not cut shorter than allowed by standard speci cations.
4 Maintenance
The REMS 4" Automatic Die Head requires no maintenance.
The dies must be cleaned with a wire brush as and when required.
NOTICE
In order to protect the unit against overloading, the drive pin on the drive tube
(2) is designed to shear. If necessary, it can be replaced by removing the inner
supporting ring (1).
Action in the e ent of a fau t
If (due to a power failure, tube breaking up) he die head must be openend
before the cutting action is complete, proceed as follows:
The clamping jaws of the REMS 4" Automatic Die Head will normally release
the workpiece if the drive motor is brie y reversed. If this does not work carefully
rotate the tightening wheel (13) anticlockwise, and jog the feed lever (8) until
the jaws release the workpiece. If necessary, lightly tap the clamped workpiece
with a hammer.
Move the die chuck towards the die head so that the jaws open.
