How to make a corner seam in sheetmetal?

How to make a corner seam in sheetmetal?

Good morning,

I want to make a nice corner seam of the two flanges I made in a piece of sheetmetal, but it won’t work as the way I want to….

These are the stapes I have made:

1) Make a planer (2mm)

2) Create a flange (#1, manipulated in the sketch option so I have two bends)

3) Create a new flange #2 with a chain. (you can see in the blue circle that the corner is not nice)

4) Create a new flange #3

5) Create a new flange #4 (see that the bend is not nice, the green circle)

How can I make the two “red” corners together. (in Inventor there is a commando “corner seam”, or “mitter” ) Did I used the wrong bend commando?

My goal is to make a box with a removable top. It has to be waterproof welded after bending.

Thanks, Stefan.

Hi Stefan,

I've been trying to solve this for a long time now. No solutions so far.

It seems that Inventor just has a better function here. Works nicely and looks good also .

Strange thing. When I make a Planer and the whole flange all around the surface of the plane, then I can select “edge treatment” and can I give a gap.

I don’t know why it doesn’t work in my former example. Sometimes you are running around to find a way, that you forget which path you have taken…..Corner-seam_2.JPG

We did the same thing with "edge treatment".

The result was not pretty and we couldn't remove extra surfaces afterwards. We edit the corners afterwards to be able to punch the plate.
