power press come up with a lot of presses. Die set comes up with the tooling.
Most of my tooling has two guide posts, not four, it will depend on the size of
the work being pressed.
I don't use die sets on the fly presses, use punch in ram and a die in the
bolster on the bottom, Hunton tooling is used
on fly presses.
sorry, bit late to help with the picture for this morning, but if I've
understood you correctly you seem to be talking about a mechanical
power press that is usually operated by a heavy flywheel?
I'm sure someone will correct me if I'm wrong but I think Sweeney &
Blocksedge just made hand operated flypresses.
Power press tooling will usually have 4 guide pillars running in either
plain or ball-bearing bushes in order to ensure alignment & die/punch
clearance. In fact all sheet metal punching and forming dies need
alignment & guidance, though some small die-sets such as those
typically made by Danly (www.danlyuk.com/home.html) only run on 2 guide
As Lionel has already mentioned, simple forming on a flypress can be
done using the Hunton universal bolster system, into which different
dies and punchs can be fitted into a single base. These aren't
usually guided on the tool as far as I know.
We run a number of small cropping and forming punch tooling in small
Danly die sets in benchtop Hare-press type pneumatic toggle machines. I
can take some pictures of these if you like and mail them over
tomorrow, if you still need them.
To make a large hole without a punch and die you need flame or laser or
water jet cutting, or a drill, file, and a lot of patience:)
