Hello community!
I would like to unfold a flat iron twisted 90° at each end. (see PC)
A trick to convert volume into sheet metal?
Otherwise how to redraw all this in sheet metal?
I didn't manage to implement the "transition fold" and "convert to sheet metal" functions
(solidworks 2019 SP4)
Thank you
If you have the premium version you have the Surface Flattened feature which should work perfectly for your request:)
Thank you alexandre,
On the other hand the result is not great:
Hello.Yes it's normal, you work on stretching the material
Correct!
That's precisely my problem!
How to find the unfolded to be able to restart the flow in 30x3mm flat iron?!
I'm blocking!
Not sure that this can be done!
Hello
Have you set the accuracy to high?
Yes, but not better!
I think we have to look at the problem the other way around. Start with a dish and twist it at each end.
Otherwise, it is impossible to obtain an unfolded in a flat iron of uniform width.
Hello
Do you need to have a unfolded frame of great precision? or do you need a representation of the part bent in to make your SW assembly?
Hello Icome
I see your difficulty how with SW you go about twisting.
I know of a flex function that allows this: except that the same part in real life will not be popular.
The only way I found was to twist it with a smoothing and then measure the lines that served as a fairly easy guide line. Then I create the flat piece for cutting. The one that is twisted can be two pieces or the same one with a config is used for the MEP.
@GT22 had solved this problem on a twist a little more complex than this one, in the sense that the finish was not on the same plane.
In any case, from experience I know that depending on the way of working in the workshop (hot or cold) with or without tools: it is difficult to obtain repeatability with a tolerance of less than 2 or 3 mm. If you want a precise center distance dimension, you have to make a twisting tool, even a simple one. Then you adjust your cut-out length as indicated above.
Tell us more about what the workshop does and especially how you do your twist with SW.
Kind regards
Thank you for your answers.
Indeed I tinker with 2 files (one twisted with approximate transitions, the other flat with an approximate length)
I'm not at the tenth on this piece, and as usual the workshop will do its best by doing its best!
I take it more as an exercise in style! and I have the impression that Solidworks does not allow you to make this ultra simple part in a clean way. That's too bad!
Try to make your room via a volume scan
to ensure the same width and thickness across your entire workpiece
You'll have to increase your radii for a softer twist
and then you will be able in theory and in practice to get a good unfold
@+ ;-)
Given what you say and the flexibility of the precious demerdologists in the workshop , it's the bending function that will do you the best job and especially very quickly.
I made a video on this bending function if by chance you don't use it often ;-)
Kind regards
Hello
If you have a little margin at the level of the representation tolerance, you can use the Flexion function,
You draw your theoretical part flat, then you twist it, it's something I regularly do on aspect parts.
edit: I just saw that there was a second page of answers :-)
+ 1 for the @ZoZo_mp solution
