Problem of recalcitrant unfolded sheet metal

[Zozo_mp]

Hello friends

I was waiting until I was retired to create Kinetic Sculpture models (a bit like that https://www.youtube.com/watch?v=9NVs8zQzQR0).

So for this strictly personal project called "waterfall without water" I have a very simple piece but it doesn't want to go flat in its entirety (glups!)

The problem is located on the Boss-extru 8 sketch.
I could get away with it by doing otherwise but a chtit' explanation on that that I don't care about it would be nice.

Hello @Zozo_mp ,
Good to see you again on the forum.
For me, 2 things are wrong with your coin:

• Boss-extru 8 with a different thickness of the base plate, SW doesn't like it too much.
  - the removal of material before conversion into sheet metal work?!? don't understand...

I would have done like this:

a direct fold and if necessary you touch up the sketches of the fold to ensure your notching.
Here is the file in 2022 version made with the 2024...

Good luck and see you...

Hello @Zozo_mp, why not go straight to sheet metal? The fact of starting with an extrusion and then a conversion to sheet metal complicates the thing for the developed.

Hello,
Cool retirement
To be able to unfold your thing you just have to add straight lengths after your extrud 1 at each end, then do your conversion to sheet metal.
For your information, no machine can end up on a sheet metal rounding. You need an extra length in rolling and a straight part in crunching.

On the other hand, everyone is right, your design is not great, not great!! Going directly with the sheet metal module would have removed a lot of sketches and other inconveniences.

To go!
Courage, it's almost the end of your apprenticeship!

Mr. (Master) @Zozo_mp !! Glad to see you again / reread (really let anyone in here... )
I like the previous comments: The heterogeneous thicknesses, Solidworks doesn't like it!
…

I don't know the equipment at your disposal but you will need a metal sheet
.472.15 x 235 x 1mm... and a big hammer.
(this is the first time that the has tested the flattening of a surface ... it's not bad at all this function...).

[Le_Bidule]

yes, that's a solution but I doubt the accuracy of the unfolded, and how come the capable rectangle is smaller than the unfolded?

[Maclane]

The capable rectangle is probably that of the unfolded Sheet Metal (the radiated areas have remained ... radiated).
At the Flat Surface quotation: length Vs Perimeter the difference is 0.002mm, it remains reasonable for this type of realization.
But, yes, this type of review is to be reserved for " information only ".

Hi @Zozo_mp .

If it can help you, my parameters used on your part during the transformation into sheet metal work in order to be able to unfold

[Le_Bidule]

With the sheet metal module, if you want to make a bend with a radius of 50 for example, you will need a higher value of the length of the folded sheet. Value to be adjusted according to the V you will use on the press brake, of course if you want your part to be feasible!!

Hello @a.eriaud
Well done for the thickness error.
In reality I made a stupider mistake because instead of doing the method like a dad. We draw everything flat and we make the folds after I wanted to do it in direct 3D and bam, I made a mistake that I'll talk about later with a new part.

Thank you

[Zozo_mp]

Hi @M-Scofield

Agree with you I always worked flat and did the folds afterwards and then I wanted to play it modern and I embossed myself.

I redo the play with the taking into account of all the remarks of colleagues

See you later

[Zozo_mp]

Thank you Maclane

I redo the piece and show you again

[Zozo_mp]

Thank you, my dear @coin37coin

I'll redo the play and I'll get back to you

To everything'

[Zozo_mp]

hello @Le_Bidule
I redo the piece without rounding, it will be easier.
I post the new part quickly.

Hello Zozo
Starting from your part, without changing the way you build it, you add a removal of the initial volume to leave only the sheet metal.

[Zozo_mp]

Hello

I didn't let you down. I'll come back to you with a simplified view.

PS: it's disgusting when you're retired time passes twice as fast.

[sbadenis]

With a remark like that, it's my day that will be twice as long!
To Plutarch as well.

[Le_Bidule]

It's not bad as a 2-month yield to modify a small sheet of nothing at all.

See you later... also.

Hello @soring

I simplified the shape because this part will be assembled with a part made in 3D printer which gives me more freedom in the shapes.

I will show you when the whole is finished. Thank you for your comments.
