ATTENTION
First check whether the working area in the machine is sufficient for the
rolling head. For this, mount the rolling head holder on the machine and
place the rolling head into the rolling head holder. Slowly move the rolling
head!
In particular when mounting on a tool turret,
check whether the rolling head is within the permissible circuit diameter.
Use an adjustable holder and adjust it accordingly.
5.2.3 Adjusting the pendulum clearance
The rolling attachment must be inserted into the holder at a slightly inclined angle,
rotated about the holder axis. This ensures that the correct roll touches the workpiece
first. During the rolling process the rolling head is then centered in the holder on the
workpiece through the pendulum clearance.
The pendulum clearance is achieved in the holder variants by two different principles:
there are holder versions available with a spring-loaded bolt (ET-31-2) in combination
with a stop bolt (ET-31-3) or holder versions available with a spring steel sheet
(ET-31-6).
NOTICE
With both holder versions make sure that the thread roll first touches the
workpiece which has the arrow direction marked on the rolling head and
which has the same rotational direction as the workpiece (page 26).
The pendulum clearance is set as follows:
a) Version with spring-loaded bolt and stop bolt:
The spring-loaded bolt (ET-31-2) can be inserted in the rolling head holder at two
positions (see Figure 15). If the upper thread roll (1) rotates in the same direction
as the workpiece (2), the spring-loaded bolt (ET-31-2) also has to be inserted in the
holder at the top (and accordingly).
Move the rolling head in front of the pre-turned workpiece (2) so that both thread
rolls (2 and 3) can pivot against the workpiece. In this position manually press
the roll rotating in the same direction against the workpiece. Adjust the stop bolt
(ET-31-3) so that the second roll has a pendulum clearance e ≈ 0.5 mm to the work-
piece. Then secure the stop bolt with the nut (ET-31-11).
ATTENTION
Make sure that the stop bolt (ET-31-3) is not located at the edge of the
plate (ET-14). Otherwise the stop bolt could slide beyond the edge of the
plate. In such a case, select the alternative location holes for the spring-
loaded bolt and the stop bolt, which are located further inwards (or further
outwards) in the rolling head holder.
