Pb on a conversion from surface to sheet metal

3D Design Volume Model

@frederic sent you in the STPE the surface flattening!

He didn't send you a step in order to unfold it because I repeat it for me this piece is not unfoldable but I could be wrong

yes, but I want a unfolded sheet metal ...

The goal is to send this part to the laser for cutting and then to bending... so I need a real unfolded sheet metal...

At worst, turn the flat surface into sheet metal and then fold it back.

24

For the laser, save the surface in DXF.

For the folding, as it is I would say that there are 2 folds on the other hand you have to find their positions and orientations.

25

I don't understand why SW can't create a volume from these surfaces? It's not very complex, it's regular with a constant thickness!! no really it surprises me that there are no solutions?

26

And yes Frederic, this is the real PB...

27

So, for me, this part is not feasible under Solidworks with the sheet metal module sorry...

 

The room seems curved, I recommend another software such as Logopress.

 

Otherwise try to convert to volume then to stl and then to sheet metal... But I don't really believe in it...

thank you Bart,

It's not very encouraging and especially very disappointing from SW...

@Bart ok it is not feasible in sheet metal in SolidWorks, but is it feasible in sheet metal with bending machines.

For my culture I would like to understand how in folding we do the "tendril" at the same time as the fold.

It's no longer bending but stamping, right?

Thank you in advance for the answer

In practice, this is possible with templates, bending, bending, etc...

 

But then to model it, it's a little more complex.

 

The LOGOPRESS software does it I think. It works in addition to Solidworks.

 

All software has its limits. In the sheet metal industry of Solidworks, the limit is there.

 

I found it very disappointing too, because from time to time you come across pieces of this kind that cause problems. But in most cases, it must be said that Solidworks is a great tool.

 

Sorry for you, after all I don't have the infused science, maybe another member will find the solution...

For me, it's 2 ply

for the position of the center of rotation see image

Bending radius about 105mm.

You just have to master the bending tool and the part is bent.

 

PS: no worries about turning the flat surface into sheet metal.

coyote,

 

We were already making this part at the factory at home, it's a flat laser cutting with the identification of the bending areas (which I had divided into about fifteen areas), then the bending quite simply. We made these parts under inventor.

Yes Fred, visually you have your room, but is your unfolded good?

 

Does the material stretch properly? I'm not so sure.

But well done!

I have a hard time looking at your piece, I go home and watch it at home in the warmth =)

 

I'll answer you in minutes tonight;)

@r.paulin so the piece is made like a boiler hopper, so you may have to try to use the "transition fold" function with the high and then the low sketch

 

38

OK Coyote I'll try.

Thank you Bart for your help...

 

Thank you also fred

39

@ Fred have you checked the lengths before and after unfolded

sometimes we have some surprise

we think that tip top is OK

but in the concrete it's in a bag and not the right one

@+ ;-))

On the other hand, Coyotte, I think it will be quite complicated because I use the support of other parts to make this one and I think it will be complicated for me to create a high and low sketch of this part on a circular body. (I don't know if I'm clear there !?!)

 

I put the play in its context in P.J
