i have here an elbow that intersects another pipe, we are
using this for a template to wrap around the elbow then cut it just
the way it looks here.. now i know this can be done in real life..
is there a way to accomplish this here?
I have modified your part to see what is going on, I thickened the
material and removed all the squares. What I have discovered is
when you make the cut to the top of the elbow you are creating
multi thickness areas, see attachment. As you know sheet metal only
works if the part is one thickness. You could not see this as your
material thickness is extremely thin.
I tend to agree with Kelvin.
If you model one segement you can unfold it. You get a really curvy
blank that, to make the complete component, would need to be welded
closed down the edges.
(You need to lose material on the inside bend and gain on the
outside).
Hence my question - "how is it done in 'real life'?".
Is this produced as a 2 stage operation?
We did get this figured out, I had to break it down into 3
pieces, i mis represented with the part i offerd, when you have the
boss breathing down your neck to get a rush job finished..well you
knw how it can go sometimes. i will post the finished product if
anyone wants to view it,possibly for there own referance. but thank
you all though.
There is no way you would be able to flatten that piece in
SW, or in real life. There is just too much material stretch and
deformation involved ... unless you are using spandex.
Why all the facets?
A simpler template might be to create a larger tube which would
slide over the actual tube.
