Steel plate bend & unbend
Steel plate bend & unbend
(OP)
Hi,
If for example, a steel plate of 1.5mm is bent 30 degrees with an internal radius of 2mm, when we flatten it again, it's lenght will increase, how much? How to calculate this?
Thanks,
Rjl

RE: Steel plate bend & unbend
The hard part is modeling, and then executing, the process of reversing the bend, which has to include a little overbend to get the part flat again, dealing with the change in K factor because of work hardening, and getting the reverse bend tooling precisely aligned with the initial bend. ... and then there's the cracking.
Just out of morbid curiosity... couldn't you just leave it flat in the first place?

I am guessing this is for a lace in a progression tool where you need to tip the lace in order to "get at" an area that would otherwise be undercut or need awkward cams and is then re-flattened for further operations, this is fairly common practice.
RE: Steel plate bend & unbend
At the moment I'm considering this will not alter, but I know that it will (very little), so if I could just know how much, it was easy to compensate.
I guess there isn't a direct formula for this.
Thank's.

I assume you will do as many critical stages (piercings, swaging etc) as possible after it has been re-flattened.
