Bending a flat pattern surface 1

[taggger]

Hi
I have a flat pattern surface for an edge for a piece of furniture. The flat pattern is to be bent so it forms a circle, but also at an angle. I've looked into the sheet metal features, but I haven't figured out a way to do it. Furthermore I've also tried with the Flex feature, but it's hard to control. The ends should not meet but have a distance of 60mm, and the pattern should be bend 75 degrees from ground. In theory, this should not be hard to do, but in practice... I have attached my SolidWorks file as well as a picture of the bent part

Hope you can help

Solidworks does not handle that kind of bend well. You can get a cylindrical ring no problem
but the conical profile will not be able to be unbent. If you want to just have a guess at what
size piece to cut out prior to forming you could take a flat pattern for a cylindrical ring with
a diameter the same size as the middle of your conical ring as a good first shot. It will likely
need a little trial and error to get it just right. How are you forming the parts?

Its some what doable, but not exactly what your wanting or how your approaching it. The file attached is 2017

@hendersdc, yeah that was my conclusion as well after trying most of the day yesterday. It is actually a ring edge for a table, so it is made from plywood and bent by hand. It is mostly for our PDM system, where it would be nice to have both.

@SBaugh, thank you very much for help. You're right, it is not exactly what I want, but more along the lines.

I actually thought SolidWorks was able to do this sort of thing better.

You should be able to unbend a cone in Solidworks. This piece would just be a slice from a cone.

You are judged not by what you know, but by what you can do.

@berkshire, yeah I think I managed to do it with a cone. But still that does not help me, does it?

taggger,

I'm not sure if i'm missing something but its quite easy to end up with a sheet metal part that will make a pattern such as your example. You can't go from flat to bent for a cone to my knowledge but doing a cone and then getting a pattern is fine. Very easy. See attached example file. NOTE: its not exactly to your size specs s i've just slapped it together and got it close.
