Operating Principle And Technical Features Of The Device; Pressure Setting Method: Force Controlled Setting (Installation) - Bollhoff RIVNUT B 4090 Manual

1 - Operating principle and technical features of the device

Pulling methods
The "pulling method" comprises
Pressure setting method: force controlled setting
F
setting force is controlled irrespective of the thickness of the workpiece.
This setting principle is particularly well suited to workpieces with variable thickness (plastic parts,
various layers...) and provides consistent setting quality.
Advantages:
I
Optimised setting into panels with thickness variations
I
Possibility to set the same Rivet Nut
I
Permits quality control (force indicator...)
I
Extended mandrel life
I
Can also sett different types of Rivet Nut

In the stroke setting method, the tool delivers a constant stroke. When
there is a variation in thickness of the workpiece there is a definite risk
that a blind rivet nut may not be set properly, or become damaged
due to the setting mandrel damaging the Rivet Nut
situation there will be premature wear of the mandrel.
This phenomenon is eliminated with the pressure setting method as the
