Putting a twist in a part????

[Bubba85]

I have this new part that I have to make and it has a 90° twist in it and I have no idea on how to achieve this. The part is made out of copper sheet, and will be in machined in flat pattern then formed. I will attach the file for any opinions on how to twist this part.

IMO, you don't need to do anything except lay out some extended wireframe and cut it.

 

That is a simple 90 degrees twist

 

But, I am left to wonder about the rest of the bends?

 

We use 3rd party software to calculate our bends

We made twist dies for this at one place I worked at years ago. Make the Helix for the slot and then make the shaft slide inside of the tube. The end with the round and hole is clamped in the shaft. You twist the shaft inside of the pipe with the slot and go from there.

I have no problem developing the flat pattern, I do those all the time. My only problem is getting that twist in the part.

Yup, sorry about that I realized I misread it

I was thinking a knee block with a bearing in it and a piece of round stock with a slot cut in it for the short end, and a handle welded to the other end. Then a clamping block mounted the twist length away from the round stock. Not clamping the other end should allow for and shrinkage of the part that the twist will creat.
