Dutch folding V-die entry (hemming V-die)
The die drawing page can be used to enter Dutch folding V-die. To define one of these, it is necessary to
indicate which are the lengths that determine the die closing by their movement and then draw a length
squashed on both sides.
- Draw the profile of the open die with the recess of the flattening part;
- Move the selection to the line to be defined like Dutch folding (vertical length);
- Press
[Flang.].
- The line defined as the flattening part will appear hatched on the drawing.
The following figure shows an example of the bending Dutch folding die.

How to enter Dutch folding pneumatic die
The die drawing page can be used to enter Dutch folding pneumatics dies.
To define one, two flattening 0.001 mm length lines must be indicated on both sides of the die.
- Draw the profile of the open die with the recess of the flattening part, but enter 0.001 mm for the flattening
lines (as though the die were closed);
- Move the selection to the line to be defined like Dutch folding (vertical length);
- Press
[Flang.];
- The line defined as the flattening part will appear hatched in the drawing;
- Once the die has been drawn, press
[Die dimensions] and digitize 1 in the “Pneumatic (1=yes 0=no) ”
field;
- Select the
[Ok] button;
- From this moment onwards, function 2 will be automatically enabled on the Dutch Folding bends.
When the bend is flattened with a pneumatic die, the die will open and will then drop in the fast mode with
the ram: the tools could touch each other during the ram fast down phase (something to be avoided). For
this reason the ram must change speed first (at a higher target). To do this is needed to change the “mute-
point” of the bend
