I have two Tabs (base) that I want to connect, and was trying the Bridge Bend, but no luck. Note, the far bottom edge remians on the same plane. Is that the reason?
Other suggestions for this transition? I've tried stacking flange, on flange, on flange, but the far edge wants to rise off that plane, or something else goes wacky. I've tried lofted flange, but we would like this to be simple brakes.
Solved! Go to Solution.
This is the best I have gotten so far. It's not perfect, but pretty close. I'm still looking for a better way to make the transition, since there is a lot of trial and error to keep the bends from interferring too much.
I believe that both edges that you want to connect need to be parallel. The reason for this is that the connecting tab needs to be planar instead of "twisted".
So I would suggest to add some material to either existing tab so that both edges become parallel when you observe them along the plane to be created.
I hope I'm making sense
Another approach would be in modeling:
Use the two outer faces to start and connect the two lines with a "ruled" face.
Then apply a blend where the bends will be. (pay attention for inside and outside radius - sheet metal thickness)
Then apply a "thicken"
after that go to NX Sheet Metal and "Convert to Sheet Metal"
That might also work pretty well.
Forget the ruled method. the ruled thickened face will flatten, but when tabs are attached it doesn't flatten anymore.
Try to add a projected curve along a vector so that you can create a plane. Then your bridge bend should work.
Sometimes I have had issues with 'thickened' sheet metal parts, in that they flatten, but the flat pattern has double lines in the bend areas, offset from each other. Then our water jet cutter doesn't know which line to cut, or has other issues.
It seemes like a valid method, and it could just be the complexity of the bends, but have you experienced this?
When using thicken to create Sheet Metal parts, I've seen best results when you immediately create the bend radius BEFORE the actual thicken with a BLEND. In that way the sheet thickness is being created in a perpindicular way to the starting face. The tricky part here is when dealing with reversing bend directions. In that case you need to be cautious about what blend radius you're using. INside radius or OUTside radius...
After that the convert to sheet metal works perfect and you wo't have double lines.
I hope this helps.
You can construct the step with discrete flanges and adjust the edges with Bend Taper. However in NX9, the bend taper command cannot add material (that was enhanced in NX10) so you need to use unbend-secondary tab-rebend for that. Here's what it would look with this method.
And, something a little more like your image.
I have attached a part built in NX9 for you to look at my method. You just need to make sure the datum is offset as it will fail if the two bend cylinders interfere.
I'm sure you could link the angled datum, flange bend angles and taper values with expressions to drive the part reliably if you have many variations.
Hope this helps a little?
