Look into Belleville disc springs (aka washer springs)

McMaster (among many other places) sells them, and has a brief
introduction to them if this link is any good (or go search
their site if it's bad - sometimes they don't like to paste
right)

McMaster is often fast, often has stuff, but is not always
cheapest if you are trying to squeeze the last penny out. They
are not infrequently cheap enough if you hunting for the
absolute best deal involves spending time that's worth anything
on the search.

For instance 9712K69 - Qty. 12 3/8 ID 3/4 OD 166 lb working load
each with a height of 0.055 inches for $4.12 - you can fit 9 in
1/2" as an inverted stack,

You mean like stacking them in alternating directions, one facing
up and then the next facing down and so on.

giving a deflection at working load of 0.099 inches for the
stack.

What is "deflection" in this context. Is it the amount that the
stack moves to the side? Is it compression? A compression of 1/10
inch?

Also, what is the meaning of "low cycle" in this expression
"low-cycle die press applications such as trimming and stamping".
I would guess that means "few cycles" or "slow cycles" but I don't
know what machine they're talking about.

Thanks.

I'm assuming you have 3/4 inch width available, and are trying
to fit 1/2" height. Other options are available if that's not
the case.
