3.3 Options
The machine can be fitted with Options. A list of the available options
is included in the Annex, Section "Options".
3.4 Forming process
There are two types of forming process with different target parame-
ters:
•
Forming to a defined diameter
•
Forming to a defined pressure
Forming to a defined diameter
This is the standard process for forming to produce hydraulic hoses.
The crimping tool closes until it reaches a pre-set diameter, regar-
dless of the required forming force. The required forming force may
be up to the machine's maximum capacity.
Optionally, it is possible to monitor the required forming pressure (=
forming force) at the time when the pre-set diameter is reached, in or-
der to detect workpiece deviations (PFM option: Pressure Force Mo-
nitoring).
Forming to a defined pressure
This process is used for special applications, e.g. insulators with a fib-
reglass rod, which are pressure-sensitive. Due to the workpiece tole-
rances, forming to a specific diameter could result in the destruction
of the workpiece. The crimping tool closes until the pre-set pressure
value is reached; there is no pressure control.
Optionally, it is possible to monitor the obtained forming diameter at
the time when the pre-set pressure is reached, in order to detect
workpiece deviations (PFM option: Pressure Force Monitoring).
Optional pressure control to the requested pre-set pressure, including
the possibility to vary the pressure built-up speed and soft approach
of the pre-set pressure (PFC function: Pressure Force Control).
