Hi...everyone...
I am ANkit and using 2013 inventor. I tried to make flat pattern from the standard 45 deg elbows have thk 0.237" and 4" dia.
But I am not able to do it.
Please help me ASAP.
I need to give this pattern to my welder to cut 45 deg elbows from 90 deg elbows.
Please find attached part and also tell me the steps to learn.
Thanks,
ANKIT
It is not possible to make a flat plate out of a pipe elbow. Duct elbow, yes. Pipe elbow, no. A torus is a non-developable surface.
I have a large NC pipe bending machine in the shop with 9" centerline radius dies and can bend elbow for you. You can also buy But-Weld elbows with the ends already beveled for welding to create your own "bent" pipe.
As previously indicated, Inventor will not (correctly) unfold that shape.
You could do it with the "Contour-Roll" feature. Don't know how you would make it on the shop floor.
You would end up with a rectangular piece of metal that would have to be rolled into a tube, a seam weld the full length and then bent in a pipe/tube bender with bending mandrels and dies.
Something like this. The flat pattern will still be a rectangle. I just did a 90 degree elbow but easily done to 45.
Opps, forgot you are only on IV2013
Ah must be exam time AGAIN - this question seems to pop up twice yearly
