Force required to bend 5" plate x 10' wide
Force required to bend 5" plate x 10' wide
(OP)
I want to cold roll a cylinder (on a pyramid plate bending rolls):
Plate thckness: 5"
Plate width: 10'0"
Material: Mild Steel
Diameter of cylinder to be rolled: 13'0"
The machine I intend to use is capable (according to the manual) of 3" thickness over 12'0" However, the build of the machine suggest that it should do considerably more.
Can anyone help ?
The machine is mechanical driven bottom rolls (rolling) 190HP. Pinch of the bottom rolls is mechanical 75 HP each.
All rolls are 800mm dia.
Working time is not a consideration as long as we can do the job.
Appreciate any advise.

RE: Force required to bend 5" plate x 10' wide
P = (0.833 * U * t^2 * L)/W
where U = ultimate tensile strength Ksi
t = plate thickness (in)
L = length of plate to bend (inches)
W = width of die opening (inches)
