Unfolded an elbow

3D Design Volume Model

Hello

 

I would like to unfold this attached piece.

 

How could I do it? Because I can't see.

 

Thanks in advance

Kind regards

Why not cut into a commercial bend? Ø323.9 1.5D  it must be right?

yes but for the cut he makes me the pattern on paper....

I'm already putting you the paper press of the right exit of the elbow in STEP (otherwise under SW 13)

For the elbow press it's a little shorter!

and by making a folded sheet swept leaving the base circle open by 1 mm?

 

EDIT: SEE IMAGE it doesn't work.... with my technique sorry

Normal, to develop an elbow, you have to break it down into several cylinders (the larger the number of cylinders and the greater the definition of the elbow) cf in PJ!!

sorry @ Valentine

 

For me the only method I see is the workshop method

The cleanliness of your room is to generate generators around the perimeter

and to measure the lengths of these generators

 

then transfer them to the elbow and draw curved lines between each stitch

 

PS: if a person has a better answer I'm all ears

Is there no other way?

Already if you start from the template of the right exit that there is after the cut, you don't have a way to draw approximately by tracing 2 or 3 points on your elbow? It must be that precise? Commercial elbows are not that regular already!!

As they say, the welding will do the rest!!!!

@ Valentine in my opinion NO

 

SolidWorks does not know how to unfold this type of part to my knowledge

 

which of + is how you shape and position your pattern for cutting

 

To make unfolded edges you need straight edges which will never be the case here

 

already that to unfold a simple collar it's the souk and it has just been released under the 2014 version

 

So guess for your play ;-)

Yes, it must be quite precise. ok so I have to figure out by tracing the generators

A bit complicated the story!

CNC machining or nothing!

Logitrace develops them very well with his elbows!!

In CN it must be a good hassle too! ^^

Where does the shape of your cutout come from? Is it a tap on an angled tube? Maybe you have to start from the shape on which the elbow is welded!?

Otherwise, you should buy Logopress !!

 

Excel complex unfolded software and works in collaboration with Solidworks

@ Valentine

 

+ you will make a generator + it will be precise,

 

PS: don't forget to name your generators at the top and bottom

 

You are under which version of solidworks what head to your final part

posted a screenshot with the dimensions

This elbow consists of an unadjusted surface,

in other words, it is not developable without deformation,

SolidWorks only supports tuned surfaces (Cone, Cylinder)

The Transition Folds function develops unadjusted surfaces but if we limit ourselves to its use according to the help it only manages adjusted surfaces ... In short, not feasible in SW

 

For this kind of problem there are software like LogoPress

 

Otherwise you can achieve results by slicing and slicing

How could I then cut my elbow into more tube? Like the link without losing my deocupe?

3D laser cutting!! I do it on large conical  bottoms, I think it must walk on elbows!!

I was talking in my 3D software.
