Bend options

You guys helped me figure out how to step bend a sheet metal part by using a lofted flange and using the triangulation bending option, I really appreciate that.

 

I have a sheet metal part that has a radius on it that will be bent using a combination of a step bender (or whatever its called) and a brake press.  For standard bends, we will use the brake, but for the radius we will use the step bender.

 

It seems I have to go either or on the bend option and am left here scratching my head on best way to portray this on a drawing to production.

Just make the large radius using the lofted flange and then add the other bends to it using the Contour Flange command.  Then you can have both bend types.

Hi @lifofadrafter

 

 

 

to get what You want, I found following way:

 

  • Create the Lofted Flange, but for the big radius only
  • Creat Flanges (You only can use the option "Bend Radius Outside" for this to get the other flanges

See video

Hi @KennyG

 

 

just seen that You were faster a couple of minutes.

 

But "Contour Flange" will not take the long edges of the "Lofted Flange"

This is the reason why I have used the standrd Flange feature

 

 

PS.: to get the correct bend angle in above video, I have used construction lines in the first sketch to get the right angle for the variable table, to use it in the formula for the bend angle

HI @lifofadrafter

 

 

 

just was in the process of answering Your intermediate post which was deleted suddenly

 

 

So see attached video where I show the complete process of creating this shape

Hi @KennyG

 

 

great job.

 

The problem I had occured due to the fact, that I had not created the sketches before and used them as You did, but tried to do it "on the fly" with profil normal to curve, but SE will not accept the edge of the Lofted Flange as base for a new Contour Profil

 

But of course, creating everything before will help a lot here.

On the other hand, difference of using Flange only afterwards to contour flange is not that big issue.

Finally theonly which counts is, wether or not YOu have done Your job, isn't it?

Re: Bend options

Now am I able to pull lofted flange bends into a bend table?
