Sheet Metal - Flange rounder edge

[Mrt_de]

Hello Everyone,

could anybody help me please and tell me how to creat such a flange on arounded edge ? please see the photo..

I just tried to make a 3D object via Extrude and then with shell command but i could not unfold the result!!

please help...

How do you expect this to be made?

I am asking ... could it be done ?

if not what is the alternative solution ! ?

The question is not designed in Inventor, but how do you expect this form to be manufactured?

The manufacturing process will be the determining factor on how to create the geometry in Inventor (or not).

No he was asking how its made in the "real world" because you need to model it as such..

Is that a rolled part with 2 half moon end caps welded on? or a stamped part or what..

In general Inventor can only flatten sheet metal parts that could be formed on a press brake where material deformation is only occurring in one plane.

Definitely not a pattern you would "unfold" in the real world.

You could roll just the arc and put the half moon end caps on it...

Maybe if you left a little bit of straight at the top of the arc you could keep it as one piece and break roll the arc portion in a finger break depending on the size of the piece.

Hi! If the rolled part is exactly the same as shown in the images you attached, it cannot be unfolded in Inventor right now. There might be options if the top and bottom faces allows a hole. Or, the top and bottom faces are not completed connexted to the cylindrical face.

Thanks!

Those methods may allow for it to be drawn and unfolded in Inventor, however, it would not be manufacturable using standard tooling.
