- [Narrator] When forming sheet metal, normally,
there's a gap between the individual flanges
on the sheet metal part, and these can be undesirable.
So, SolidWorks gives us a couple tools for dealing
with this, and it's called, generally, a closed corner.
So right up here, under the sheet metal tab,
you see we have one called corners,
and under there is closed corners.
And that's what we're going to be using in this video.
But before we do that, let's go ahead
and create one more flange.
So go over here to edge flange,
choose this edge right here,
let's go ahead and drag that up,
and instead of just a blind length,
let's go ahead and say up to vertex.
Let's go ahead and choose one of those edges,
and click on okay. All right.
Now, in this corner here, you can see that we've
removed some material here because we had that
trim side bends option. But, over here on the other side,
same basic set up. If you go back to the edge flange,
if you go and turn that off, so trim side bends,
turn that off, you can see we actually get
kind of an ugly little corner here and it's going
to be trying to tear that material.
So that's generally what we don't want.
We also don't want this big old gap here,
between the flanges. So let me show you how to fix that up.
So the first thing we want to do is
just go over and create that closed corner.
So go over here to corners, click on closed corner,
faces to extend. I want to extend this face right there.
All right? And, notice it's going to kind of
overlap this, and if we have a couple different options.
We can overlap in this direction,
we can overlap in that direction,
or we can do a corner-to-corner or butt corner.
So let's try that butt corner first.
There it is. And that gives you a nice place
you could put a weld bead if you're going to be
welding these two corners together.
Now, let's go over here to the other side
and try a different style of closed corner.
This one here, I'm gonna go ahead and use
the overlap in this direction here.
My face to extend is going to be this one here.
And click on that one.
So now you've got this one kind of overlapping,
and it kind of brings in this lower corner here
and that looks pretty good.
All right, this also gives us an excellent opportunity,
if we wanted to create some type of an overlap,
or, like, a riveted or spot welded corner.
So I can come over here to edge flange,
maybe choose this inside edge here,
and we can bring that in here a little bit.
That looks pretty good.
Notice we are using the inside style of flange.
Down here you can see a little material on the inside.
If you had material on the outside,
it would interfere. That would be bad.
And this one would be even worse.
So make sure you're choosing material inside,
and then to find the length of the flange;
let's go ahead and just kind of bump this up a little bit,
and then click on okay. And now you've got
this nice, bent flange here on the inside.
You could spot weld, or rib those together.
And notice, it does open up this lower corner here.
You could chart up, apply some type of corner
treatment there. But if you start stretching the
material too much, you might end up with some issues.
So generally, if you're going to be doing
flanges on the inside and and then welding or butting
them together, it's a good idea to kind of leave
a little bit of a hole here, or do something that's gonna
clean this up. But don't do too much,
because sometimes you're stretching that material,
you can run into issues.
So that's a couple different ways you can use
the corner treatment, and use the closed corner
to really clean up your parts, make 'em look
a little bit nicer, for when you actually
flatten it out, when you actually bend it,
you get a nice clean part that you can easily
weld the corners, rivet, or spot weld.
