4.2.1 Standard press stroke
Standard press stroke 4- Funktion_Pressenhub_Standard_Basis
Action of the protected field during an uninterrupted press stroke:
1
Initial status:
The press is at top dead centre.
The operator initiates a press stroke
with the foot switch. The protected
field is clear.
2
Rapid traverse:
Upper tool (upper die) moves with a
fast closing speed (rapid traverse >10
mm/s). Controller initiates the braking
process. The protected field is clear.
3
Creep speed mode reached: The
closing speed must have reached
creep speed mode before the protect-
ed field reaches the workpiece (
≤ 10
mm/s). The safety system receives
the signal for creep speed mode from
the press brake. The protected field is
deactivated.
4
The protected field is overridden
(muted) during creep speed mode
and does not cause the press stroke
to STOP.
