Base Plate Properties For Die Cutting Press
Base Plate Properties For Die Cutting Press
(OP)
An automatic two-axis die cutting press uses a die board with steel knives to cut leather on a nylon board. Below the nylon board, which is usually 1/2" thick, is a base plate made of metal, usually 1/8" thick.
The head of the press usually works in the center portion of the press, exerting up to 20 tons of force, resulting in a bent nylon board, which is normal, and is required to be turned over at the end of every shift, to have a flat board. The cycle is repeated. However, the same bend is introduced in the metal base board as well, which bends in a matter of days and weeks. However, it is cumbersome to turn it over, and is not intended to.
What type of metal and properties should this metal base have, in order not to bend so easily? Is a hardened steel the answer? How about spring steel? And, can't go thicker than 1/8". Any advice?

I think a call is warranted to the following companies.

If you can't make the total stack any thicker you may need to make the urethane thinner and add to the metal.
You may also be stamping too deep. If you make the plate stronger you will need to shorten the stroke a bit.

Other than those, try to bolt down the plate, if you can.
