Complex Square to Round

[shaberli]

I am trying to create a complex square to round that attaches perpendicular to the axis of a cylinder. The problem I have is the square opening has to follow the cylinder.

I tried to loft it, and on the 1st profile I select the circle, and on the 2nd since theres multple profiles, I can't select more then one. I am making theis parametric that accesses an excel file, but the problem I have is creating it.

Is there another way of doing this?

I attached the sq to rnd profile file (Inventor 2015)

Thanks,

I do not see a square or a cylinder in that file?

I suspect though, that the solution will be pretty simple as the geometry in your file is pretty simple.

Any more info?  Images of a similar part? A had drawn sketch?

BTW - none of the Workplanes in your file are needed and I suspect only 2 sketches are needed (maybe only one).

quick response.....

Sure, here a 2d cad in pdf. Ignore the refractory internals.

HI!

There's something like that?

Hi!

I believe is the first option...

Check the video.

Carlos....

No not quite ont the top image of your post,

but the lower image has some posibilities.....

[CCarreiras]

Ok...

two ways...

Anyway, you can make the sketches a lot more simple. You don't need so many sketches...

check the video...

Its helpful Carlos and I appreciate it.

Unfortunately there are design criteria that I don't think I can over come.

1.) The transition attach to the main cylinder needs to be tangent (so inpingement on the process is reduced.) We also need to fabricate (unfold) off the file drawing.

2.) The Main Cylinder Needs to be a variable and still be tangent, because we have like items, or as a result of emperical information feed back from our process which these cyclones will be installed in our plant.

3.) I would like it to be a fabricated part where we can unfold it.

I am going to look at it,..... when I'm a fresh.

If I pick something up I missed, I'll let you know.

Thanks,

My first interpretation.

Is this the first time you have made one of these things?

Do you have an image of an actual assembly?

My second interpretation.

Version 3 (I can keep this up all night).

Tell me when to stop.

My attempt attached.

please note that I disregarded dimensions and I'm not fully clear of the intent.

JD!ather, , sorry about not getting back sooner, he second and third version looks what I'm trying to do. How'd you do that?

We had it as an Autocard drawing

Autocard?  Do you mean AutoCAD? 

You posted an pdf file (of a bitmap image) not a dwg or vector image.  I can't read the dimensions.  What are your intended units?

[shaberli]

Yes AutoCAD,,

Units are inches, we have issues on the process, where the process tears up the internal refractory. So the square to round needs to be tangent on the outside of the main cylinder, when I change the diameter of the main cylinder body, the outside transition also changes. And least that's my intent.

That s the reason I intend to make in parametric off a excel file.

I was expecting it to be a much larger part - thought it would be feet.

What is the material?

What is the material thickness?

What is the inside bend radius?

Getting a fully associate parametric model will be fairly easy once all of the questions regarding design intent are understood.

[shaberli]

JD Thank you for your help.

Material is 304 Stainless

Thickness is 3/16" Plate

Inside Bend Radius. On the Transition is 4.155" (8" Sch 10 pipe) on the Main Cylinder 10-1/2" to 13-1/2"

More detailed sketch:

Die formed or brake formed?

[shaberli]

Brake formed

Take a look at attached and then tell me what you really want.

Hmmm, well that is a strange one.

Delete the Flat Pattern and recreate it.
