Bending and unbending tubing

Phenom
Phenom

I have a user, that is trying to model, bend, and then unbend a piece of tubing, using sheet metal module.  He wants the unbent form, so it can be laser cut, and the bent for use in the assembly.

 

he's had no luck, and I've tried to help, but because it's not true sheet metal, and bends and normal cut outs are 90° to each other, they don't play well together.

 

So far, my best solution is to model it unbent, extract a body at time stamp, and then bend the original into the finished shape.  I was actually surprised he got the "Bend" feature to work, on hollow tubing.

 

Is there a better tool, or module to do this?  Mechanical routing maybe?

May be my model will be useful.

No, but I can upload the file.  You can see he started with a linked body, which was the original 3 piece tube, as reference.

 

I think you can follow the rest of his workflow.  The extracted body, was added by me, as a way to preserve the profile needed for laser cutting the tube with the notches.

Dave I took your stock body and used split body and move face to get it into the final position. I have attached the part file. I will think about a way I maybe able to do this by starting with the finished shape to move it into the straight shape.

Thanks.  It just seems like we can't the the only company that would notch, and bend rectangular tubing like this, so I figured there would be some method, or capability within NX.

Since no favorable answer here for this simple task within NX, I just look how easy it could be with other software.

It took me 15 minutes  to build a model with parametic capablity. It may take another 5 minutes to get a drawing and a DXF file.

@AmyReyes ; 

I’m trying to insert videos in MP4 & AVI formats with the video upload (Camera Icon) function; but it isn’t working anymore. Could you please check?

I could download the videos, just not watch in the webpage.

 

That said, I could probably build a fully sheet metal file like that in NX, and get it to unfold, but ideally I'd like a tool that will bend/unbend rectangular tubing.  Getting the notches laser cut, and then folding, would seem to be a common industry practice.

Hi @mike_fdo

 

I am able to attach videos without issue using the camera icon. If you are using Internet Explorer, please check your browser settings. Compatbility View Settings must be unchecked/set to off.

That is usually what causes most of the issues you're describing. Let me know if this works, and if not, I'll continue to work with you to find a solution. 

 

Thanks!
