The application is also able to check
whether a certain part can be produced
by simply reverting the steps and
thereby starting the bending process
from the other end. If the user selects
a bending machine with dies of the
same radius and diameter on
different layers or stacks, Kolli
automatically considers these
as alternatives. Collisions can
also be avoided by correction
feeds, with further possibilities
examined by
Kolli.
The latest
version of this
software is
Kolli7, which
operates with
a unitized
structure. All
editing functions are
designed as independent
applications to capture an individual
workshop environment.
This includes the construction of a user’s
own bending machine with a 3D-machine-
editor, design of toolsets with a 3D-tool-
editor, and collecting material data with a
material-manager.
The entire bending process can be
visualized in the simulation, with details
reviewed by pausing the animation and
zooming into critical areas. In certain
situations where large batches of pipes
require bending, the application can be
used to perform the entire simulation and
calculation.
The calculation focuses on the correction
of the length of pipes and the computation
of the right bending parameters.
These parameters include the extended
bending angle for spring-back correction
and the shortened straight parts
between the bows as correction of the
stretching. The application can also
calculate the relative and absolute
flange positions in cases of bending
with two flanges.
3R Software Solutions cooperates
closely with the various manufacturers of
bending/forming benches. This ensures
that Kolli import and export interfaces
are created for the well-known design
systems and the most common bending
machines.
The different SPS-systems can be
directly fed with bending and forming data
with pipes manufactured sequentially.
