making a Platen press from a H-frame Hydraulic press
(OP)
Ok,
I'm a software engineer, not a structural engineer, but I have a question about the strength of plate steel. I know there are many types of steel out there, but let's assume the "default" stuff you would buy from "Joe's steel" down the road..ok I have a 50 ton H-frame hydrualic press. what I'm trying to do is take the force from the 3" diameter ram and distribute it over a 48" X 14" area. What thickness of steel would be required to distrubute the actual usage weight of 43 tons evenly over this area with no/minimal bending?

the steel will rest flat atop a concrete mold made from 4000# concrete, with rebar, about 6 or 8" thick. this top/female part will rest on maple veneer plies (skateboard manufacture), and that in tern will rest on the male concrete mold. this male mold will sit flat on the press's bed. My concern is any bending will crack the concrete, and not give an even distribution of weight across the mold.

I wish I had the time to calculate the deflection-I'll ask my wife-she's the mech. eng. of the family!

Go to my web site at the end of my email and there you will find an email address for me. Once I have your email address I will send you some cut sheets that I have used for years to calculate stress. They will be in PDF format. So send me an email. Some day I am going to have to figure out how to post some of these things on this site for everybody.
Sincerely yours,
