Sheet metal bent in the shape of a propeller

Is it that hard?

 

Draw a helix or spiral and then balance a sweep either by volume and converted into sheet metal or with a bent base swept.

22

Ok, yes it's not easy  here's what I was able to achieve

Use the config to see the different parts

I added a configue

To get the Dev, I put a plan in the form, then I put a sketch of the Øint of the shape in it, then I put an opening in it and leave the sketch. I create a sketch on the face of the profile and put the profile on it, then quit, and then I use the folded, swept sheet metal function and delete the original part so that only the unfoldable part remains. See PJ,

BUT THE RESULT IS NOT CONSISTENT WITH REALITY

Hello

At Leblanc I can't open the room

I am of the opinion that you need a stamping tool but I don't know how to do it...

otherwise I made the propeller by deformation but the result is not great!

I'm not a sheet metal worker but if you want two fold-out bodies (I don't know if that's the solution to make this kind of part), you can maybe use the method in the attachment.

PS: You can hide the original named body, it only serves to highlight the geometric similarity with the original body.

I made two configs to have the unfolded of each body

Hello

Oh dear, you must have an earlier version of solidworks 2016. 

Is there a way to record a piece as a step while keeping the configurations?

Otherwise I have to put them all one by one...

I have the same result as Mick.Cordero to within 0.09mm.

29

indeed I have SLD 2015

But with a step, I should be able to recover the functions but maybe not the configs.

@david.heyraud.fs , I attached the file in 2015 version in my previous reply.

I'm attaching the step, but it would be easier for you to take Mick.Cordero's play, the gap is tiny for such a piece. This difference must be due to the fact that Mick.Cordero took a single guide curve to make two sweeps, while I took one curve per body.

I was able to do with deformation

Re, I probably quit before the end of the load...

You should try to make it happen, it's not that complicated with this method.

Not bad, good idea but should it unfold in this direction?

The design of this room would be more complex.

You should try with a stamping.

35

yes the meaning is easily modified

but as soon as I reduce the opening (the cutting of the sheet metal) it gets complicated

As far as stamping is concerned, I have no notion

36

There are a lot of very nice tutorials on Lynkoa. Have you watched Mick.Cordero's play?

37

Thank you

I got the 3D

I notice that the piece is made in 2 pieces

so when you do the unfolded, the length is not the right one

 Yes, it's normal, you have two pieces, so two flattens. Look at the attached word file

Oops, so much for me. Yes indeed there is 1 micron difference on your images, but I think there must be a very important IT for this kind of part. Insulate the parts when you measure, it's safer. I find an identical result.

Yes I looked at his piece in 2015 and also the step.

That's when I realized that the piece was in 2 parts.

but I have to limit the welds, so the part has to be bent

I consulted the tutorials on stamping, but I don't understand how to deform the "sheet metal" by a tool on SLD

What is the process?

1-Create the part before stamping?

2-Create the stamping tool?

3-Apply the tool to the part to be stamped?
