Sheet metal cylinder with flange

[aamoroso]

I am trying to figure out a way to draw a Sheet metal cylinder (dia 6&quot with a .313 flange at the bottom of it. Any ideas????

A picture would help. If you wish, send a small (<300 Kb) picture to the email address in my profile.

I think he's talking about an &quot;L&quot; shape revolved into a cylinder. I don't think SW will be able to unfold a part like this. It will only unfold linear bends, not curved.

You got it Mad, it is (or should I say would be)an L revolved. In the previous years we have been faking the flat by adding the flange material I was hoping something would have been changed by now. Thanks for the time guys.

I am kinda a novice when it comes to what can actually be manufactured out of sheet metal. I don't quite see how that part can be manufactured. It seems like an aweful lot of &quot;stretching&quot; at the short leg of the &quot;L&quot;. Please inform me as to how this part gets mad in the real world.

Thanks,

I suspect it would be roll-formed. Many bearings (Garlock DU Bearings) are made in this shape, it's very common.

Yes, roll-formed or deep pressed. If these are the cases, there's no point of using sheet metal. Am I right?

Yeah, its roll formed then welded along the seam.

So I think the best way is to use a revolve feature, as SW does not understand nothing about plastic deformation processes (other than the &quot;normal&quot; sheet metal). If it's important to you the deformation analysis, you should search for apropriate software.
