RE: Conventional punch press dies!! Fastening Them
Each punch design can be different. Show a photograph of the problem, I cannot interpret your question from your words. The dies are usually set into the holder, not bolted at all. What do you mean by "clamped" ?

You are judged not by what you know, but by what you can do.

Now if you mean "clamp" as in a manually tightened threaded screw C-clamp or welders clamp . . . Never use these.
It is better to have enough ideas for some of them to be wrong, than to be always right by having no ideas at all.

Also, those kinds of clamps may not have the tensile strength to adequately resist stripping forces on the upstroke in cases a fixed stripper is employed.

But as for the tooling in your photos ... yep, that's scary.

I have looked through your pictures again, Unless you are showing something I cannot see , I do not even see a C clamp in the picture .
What I see are three UniPunches " Blue" bolted to a setup plate that appears to be about 1/2" thick. I see two gauge stops and one end stop "Red " and the restraining dog clamps , natural metal color. The UniPunch is a self contained punch and die set that has its own return spring and material ejection chute. The setup plate appears to be properly dogged down with Dog clamps ( setup clamps) The stroke of the press , or converted machine would be adjusted so as to bottom out at the point where the material just punched through to avoid excessive wear on the punch and die set Look at the tools in the link I have put here. http://www.toolsetinc.com/our_products.html You will see your Blue " C clamps ", which appear to be LP series punches.

I agree that the dog clamps are a bit marginal, clamping down on that square tubing, there is not a lot of leverage. I would rather see the tubing ,or a solid block, or a proper pair of Vee toothed step blocks, placed behind the hold down bolt to give more leverage, but it does not look like the setup man has a lot of room there.
But this was not what you appeared to be complaining about , you were referring to C clamps Per your quote " what I mean is manually tightened screw C-clamps." which the hold down dogs are definitely not. However if the setup plate is sufficiently ridgid and does not move on the press it should be ok to run.
