I read an article about applying to much force to a small area of the press brake bed, So yes, it makes sense, my brake is a 12' x 240 ton brake, you dont want to apply 240 tons of force over a 2' area due to damaging the bed or the ram... ( Not to mention the die set itself )
The article said if you 150 ton brake that is 10' between centers, the max tonnage per ft you should apply to the bed itself is 25 tons, I did some calculations and come up with the max tonnage per ft that my bed can handle is 39.96 tons per ft.
So, the minimum die you should use when bending 3/4" plate is 10 times material thickness which would be a 7-1/2" bottom die, but lets say I only have a 7" die that would require 42.2 tons per ft which would exceed my tons per ft., even though I may only be bending a 36" piece which only requires 126.6 tons of force, I may be damaging the bed and ram...
This is definitely something that I might not have thought of if I didnt run across this artcle.
