Sheet metal rules for pan/folding brake

[Anonymous]

Hi, Im trying to figure out what settings I would use in the sheet metal environment to set up bends for a box and pan or folding brake?  Fusion is setup to bend flanges via a press brake where the bend is point is centered and the bend radius is equal on both sides of the bend.  Unfortunately, we dont have one of those and instead have a folding brake where one half of the metal is held static and the other side is bent.  Due to this difference, bend lines that are calculated are entirely incorrect and the entire model is wrong as a result (flanges end up too long or too short). 

Curious if there are any rule settings I should change to account for this?  This is a big deal right now for me as Im getting ready to model a rather large fuel tank that is fairly complex and uses a very expensive material, Titanium container, so I gotta get this right.  Thanks in advance, hope there is a work around for this.

Hi @Anonymous 

I think I know what you mean here. I believe what you're looking for is the bend line position under the bend dialog box. I think for the folding brake you'll want to use the 'start' line position.

Let me know if I missed the mark here or if that solves your issue.

Cheers,

Thats what I want, but I just noticed that doesnt work for the flange command only the bend command.  How would I go about doing this using the flange tool as what you did is exactly what I want to do.  The commands are different and they dont change the bend position, only where the flange is placed (such as inside or outside).  

Maybe I can use the flange tool do an unfold and then do bends for each piece to work around that?

Hi @Anonymous 

I think 'adjacent' is the bend position you're looking for in the Flage tool. That keeps the full size of the original part and adds the bend outside the selected edge.

Does that work?

Thanks,

No that just moves the location of the bend not where the bend is made (in relation to the bend itself, might be confusing sounding, but thats actually my whole problem).  The bend tool is what I need to use, but the flange tool has the functionality of working like the extrude tool as opposed to having to manually draw an unfolded shape before bending. 

I may do some experiments and see if doing a flange and then unfolding as opposed to the pattern tool will work by creating the solid with the fold lines where they'd be without the modeled k factor and such then use the bend tool using those construction lines to get the proper model AND proper bend lines to use in our brake.

Wondering if any solutions for an efficient box-pan brake implementation have been found...

Hey, so I'm guessing you just want to change the radius of your bend to what it will be with your box brake. I would try to a sample bend, note what the radius is, then just do a radius over ride for that flange with the true radius of your tooling. When you set it up, don't use what fusion tells you as the center of your bend line, but one of the outer two lines based on how you are bending it, as in how you line it up on your brake to bend it. Aka line up the start of your bend on the edge of your tooth, if that makes sense. I would try a test piece and see how close that gets you. I personally havent done it, but that is how I would go about figuring it out. I'm bad at explaining this kinda stuff so sorry in advance if it doesn't make sense.

During the design of flanges do not forget to use the realistic dimensions that bigger than minimum required for such bend))))
