Trying to Convert to sheet Metal Successfully 2

[Magicblack]

Hi all,

I have been trying to convert this product into sheet metal successfully but have not achieved my goal yet. Solidworks converts it to sheet metal but I cannot preview the flat pattern as it says there a parts within your model which cannot be unbent.

Can any one help.

Iges attached.

Either the part is not modeled correctly or significant stretching is required. See attached image of flat.

I see a problem with the little tab with the round hole because it is located on a large radius bend.

if you could change the geometry so that the tab came off of the flat, it may work better.

Thanks for the feedback.


applejack2, the tab exists in other products previously designed and the forming has not been an issue...........but it also has not been a walk in the park when it comes to converting either in the past.

Rollupswx, I made some adjustments so there are no interferences but you maybe correct about stretching of the material as that maybe causing solidworks not to recognize the bending. After converting and suppressing the inner forming, the product can be flattened.

Can you shed some light on how you were able to convert in flat in the jpeg you previously attached?

I have revised the iges and reattached the file.

I get an interference of .25.
I don't think it was expected to stretch that much - I suspect a design error.
In any case if it is expected to stretch that much the starting flat would not be solved in Inventor or SolidWorks.

So i revised the part to confirm there were no interferences anymore. I converted the large radius from the side profile into straight lines so the product doesn't need to stretch at all.

I completed half the model with out the tab and was successful to convert it to sheet metal and flattened it. I suppressed the flatten feature and then added an edge flange to produce the required tab and the product was then unable to flatten. On top of that with or without the tab, once the solid body is mirrored it is unable to flatten for some odd reason.

I recently did a model and completed half the body, converted to sheet metal and mirrored it and it was successful to flatten while this model is not.

I suppose solidworks doesn't agree with having a radius tab within a radius but the mirrored body part is perplexing.

Thanks ahead for any help that follows.

This one flattened fine in Inventor, let me give it a go in SolidWorks - back in a bit.

SWx 2010 doesn't like this bend.
Can you attach the native file with history tree here?

 

[Magicblack]

attached you will find the native file.

i'm using solidworks 2009.

 

[applejack2]

it took some work, but here it is in solidworks 2011.

... and screen capture.

The links you made are not working.

Can you double check the links, if possible have them available in solidworks 2009 or 2010 or just iges?

 

[applejack2]

recreated in solidworks 2009.

the links work for me, can anyone else verify if my links work?

Apple,

Nope they aren't working for me neither I'm afraid.

AJ2...
None of your links are downloading. links from others work fine???

CBL,

I found your email address (@lycos) on another post. If I email you the file, can you upload it for me?
