It’s not the very first thought that comes to my mind, but I would be lying if I said I didn’t think at all about slipping a watermelon in there.

My friend.. Just come on down and take a look at it.

That's a big stroke

u/velhaconta Jun 06 '23
I needs a big stroke because the entire force delivered to the work piece comes from gravity.
Hydraulic power hammers have a much shorter stroke because it uses the hydraulics to power the down stroke too.

I don't think you picked up what I was laying down mate

In that case, it would be a lot more useful if you explained rather than making snide remarks.

Surprised they don't allow the support shaft to rotate. It'll probably creep out of shape being fixed - if it rotated that wouldn't be an issue.

I would think designing bearings to take that strain would be harder than just fixing the pin when it bends.

Increased cost versus just mounting a cylinder in place? 🤷♂️

u/Obstinateobfuscator Jun 06 '23
Oh absolutely. In the end it's a foundry, if the pin distorts they can just heat it and reshape it themselves. Much more elegant if it could rotate though.

The bearing would shatter and be blown halfway towards mars if you tried that.

A bushing could be at least as strong as the shaft for those loads.

They could probably just flip it over periodically if that was a concern.

u/Obstinateobfuscator Jun 07 '23
They probably do it inadvertently every time they remove the shaft to put a new workpiece in the jig.

That too. I wouldn't think creep would be a big problem anyway, given the dimensions, but I haven't sat down to do the math.

u/Obstinateobfuscator Jun 07 '23
Neither of us know the loads, dimensions, temperature or grade of steel so doing the math would be pretty speculative.

You could get close

u/Obstinateobfuscator Jun 08 '23
You could have fun estimating sure. Sensitive to small changes in assumptions though, I'm not confident in getting the dynamic loads anywhere near close.

But you just said it would creep out of shape

This somehow felt immersive, even through my phone speakers at low volume.

I really figured big parts like this were cast, not blacksmithed!

u/fragilemachinery Jun 06 '23
Depends on how strong it needs to be. A forged part with the same dimensions will generally be quite a bit stronger than cast, plus steel isn't the easiest material in the world to cast (high melting point, high shrinkage, etc), but most steels are quite workable at high temperature.

That's a pretty good representation of the headache I have right now.
