Designate the tool or surface(s) and on your model for the bottom pad.
The bottom pad is attached to the bottom die with a spring
or hydraulic cushion. The bottom pad grips the blank against the top die in order to
maintain the proper positioning and avoid distortion of the blank during a forming
operation. The configuration also involves selecting the bottom die to which the bottom
pad attaches.
-
Select an operation, then from the tool set that appears, select the
Bottom Pad.
-
On the guide bar, choose Part or
Surfaces.
-
If you choose Part, on the model, select an option from
the table below based on your desired result, and then click to confirm.
-
If you choose Surfaces, on the model, select the
surface(s) you want to designate as the bottom pad, and then click to
confirm.
Note: If you modify the blank thickness, you must reconfigure the tools created
by offset.
-
In the microdialog, click the option to apply a Force or
maintain a Gap. For force, type in a value for the
Initial Force and the Final Force, or click the Calculate the Medium
Force button .
Note: The gap value is the material thickness plus 20%.
-
Define the stroke, velocity, and Coulomb friction coefficient.
-
In the microdialog, to set the stroke value to the closed position of
the tools, select . To specify a value, select the pencil tool
, type in a value, and press Enter.
Note: If you define the stroke value to be larger than the
auto-calculated or closed position, the open position of the tool
automatically repositions to match the stroke value to prevent a
collision with the bottom die.
-
To define the Coulomb friction coefficient, in the microdialog, enter a
value next to the icon .
-
Click to confirm.
-
On the guide bar, click Attach Tool. The preselected
bottom die is highlighted. Click to confirm or select a different bottom
die.
-
Click to confirm the configuration of the bottom pad.
