I'd use a bottle jack under the cutting edge.....then a heavy chain hooked on both front corners and under the bottle jack.....pumping the jack up will straighten the edge, moving the jack to one side or the other if need be
The best way to keep it flat would be to throw those clamp on forks in the scrap pile where they belong and get some SSQA forks.
I didn't bend it. It was already bent when I got it.What did you do to bend it if a 30 ton press barely bent it back?
