strong-back bends (sheetmetal bend gussets)

Discussion in 'SolidWorks' started by Not Necessarily Me, Jan 18, 2007.

  1. I know this has been discussed in the past. I was wondering if someone has
    come up with an elegant (i.e. easy) way to represent these on sheetmetal
    parts? I'm still on 2006, maybe 2007 addresses this directly since
    Solidedge now has this feature. I have a gusset in my design library that I
    picked up somewhere but I can't figure out how to place it on a part.

    Any help greatly appreciated.

  2. Well to answer my on post. I got through the project requiring the strong
    backs but the way I did them is not pretty and actually I hope no one ever
    sees the part file. I did one using extrude, then draft, then fillet (2x),
    then a cut and more fillets. It looked great so I decided to array/mirror
    it all over the part but SW wouldn't let me do this. So I arrayed/mirroed
    what I could and then finish out each individual gusset (there were 12 of
    them). What a PITA!

    I've done pretty much the same thing. Make one part with extrudes and
    cuts depending on which side of the part the gussets are formed, draft,
    fillet, then shell, that represents the finished folded part. This part
    won't turn into sheet metal - no bends found. So then I make a separate
    sheet metal part, without the gussets that can be unfolded for the flat
    layout. You can add a sketch for the location of the gussets in the
    flat part if needed. Not pretty but it works.

    I'd tried applying a forming tool I made to put in the gussets after
    adding a flatten feature, but it failed to fold back up. I also tried
    putting in a forming tool from a plane at 45 degrees from one surface.
    That didn't work either. I haven't seen anything added in SW2007 to do
    this either. This is a very common sheet metal operation for both
    stamping and press brake work, but must be difficult to program. The
    only other thing I've wanted for sheet metal functionality was added
    when lofted sheet metal parts were added a couple releases ago.

    Don't be embarrassed or shy about the part you created. If someone
    rolls their eyes at it ask them to demonstrate a more elegant method.
    If you are sending the part to a client be proud of your work. The
    limitation in this case seems to be software, not your skills.

  4. Diego,

    Just one thought about your post. Even though it sounds like we went
    through the same process, you might want to consider separate configurations
    instead of files. I have one config with the strongbacks that show up on
    the formed views and another config where they are supressed. I use the
    config with the supressed strongbacks to place the flat layout view since
    the strongbacks in theory do not affect the flat layout (the press brake
    operators will argue this point.). Thanks for the encouragement, we all
    need some of that from day to day.

    Have a great day,

    i posted one a while back.

    i don't have the link on my page any longer.

    use the default config for the flat-pattern.
    add a configuration to display the strong backs.

    the reason the part will not unfold is the forming tool goes across a bend.
    regardless of where it lands on a part, no forming tool will unfold.

    i can you send an example.

    Who knows what if would take to alter the forum's charter to allow image
    attachments? What percentage of us are so bandwidth limited that we can't
    afford to download images? I realize some out there still pay per byte, but
    is it really that expensive versus the benefits?

    Links to web provision are allowed, are they not?

    I know of no reason why links to images elsewhere should be a problem.

    Looking into it a bit, it seems that the goup would have to become
    comp.cad.solidworks.binaries in order for it to be good manners to post
    pictures here. I suppose there aren't enough people who care enough to go
    to the bother of basically creating a new group. Ah well. We'd only get
    spammed with porn anyway, right?

    That does sound like a bigger problem. Thanks for the education.
