Need help, Creating a sheetmetal Panels having 3D Bends

[premchand.potdar]

Hello All,

I am creating a sheet metal panel which has 3D bends, I have tried Everything to solve the problem but can't find the solution at all. Attached are the images where I will try to explain the problem I am experiencing. 

In Image 1 is the Panel that I am creating, I have created the Front and Back Panels which has sort of Curve bend and Circular cut in the bottom. 

In order to Close the panels in top and bottom I need to model closing panels which is creating lot of issues for me, hence I have used sweep command and just a 3D model and not sheet metal part. But even this doesnt sit exactly between the two panels and the angles don't add up. 

May be I can send over the model if anybody would like to solve this issue and let me know what I might be missing here. 

Thanks in Advance.

Attach *.ipt file(s).

Are you trying to apply a "flange" to the curved edge of the part?

You can loft a single edge. Offset a plane for the width.

Hello,

Will send you in 2 parts message. PL-001 is the assembly, the most complicated parts are PL-102-1 and Pl-105.

Hello,

Nope, Since the complexity of manufacturing the part and cost involved we are trying to do it in seperate parts. 

Some more images for your reference in the attachments

Hello 

Interesting will give a try, but will it work if the plate is circular even. SEe more images in the attachment

I'm not sure of your final dim's BUT I'm including a part and screen shot on how to make these. Now the flat pattern is a bit problematic in that if you plan to roll the pieces then it doesn't like it, but if you go the press brake route then easy-peezy. You control the locations by the points for arcs and plane. If you still have issues then post a note.

Hi Folks,

I am still trying to understand the design intent. But, I think this can be done using a multi-solid body part. Instead of creating individual parts, it is quicker to define geometry within just one part. It is because the panels have spatial and sizing dependency.

I am wondering if Ruled Surface can help here. It can create a protruded surface along a selected edge at a given angle (tangent or normal). Then thicken the surface into a solid body.

Once the bodies are defined, use Make Components to push the solids out as individual parts. Add detail features and create flat pattern in each part.

Many thanks!

[gmwi]

Yes, you can make one solid piece and then build around it. I've done that before also. Don't worry there are multiple ways to get to a design. The Cad-Police won't get you.

OK, this took a lot of trial and error, but here is one way (the only way I've found) to accomplish what you want.  I used the multi-body master part method to model four of the parts in your assembly, all of which can be derived from the master to their own individual parts to be flat patterned.  I have included just the sloping one in this message, but the others are easily created.  I also did not complete the joining slots & tabs for the top part, but again, you can finish that work yourself.  Ask again if you need more help with it.

It did work really well. Took a bit of time to understand the process and implement this solution for myself but it did work. Thanks for the help. Have been using Solidworks for many years and started using Inventor from a year hence took time for me :-).

[premchand.potdar]

Thank you very much for taking your time and helping me to solve this issue. This is what I was looking for actually. Really appreciate the effort.
Thanks again 🙂
