safety plug

[massimo1990]

Good evening to all,
I am a new member, I have a problem with a safety plug mounted on a transfer press.
practically in phase of extraction of the piece through a lower punch, commanded by an auction, which is operated by a cam connected to a shaft of diameter about 300mm, I break the safety plug that is a c45 not tempered diameter 5mm, set between the punch and the rod.
My doubt is that it is a plug under size for the kind of effort you have to make.
That said my question is leaving the diameter unchanged (5mm) which load can support a 300mm diameter shaft driven by its bearings say big ones? looking for the fracture load of my plug that I have, I arrived at a force of 200kg but I'm not sure of the result! .
I thank anyone who can give me useful information.

I apologize for the poem I wanted to try to be as clear as possible, and I hope to be state.

I'll tell you right away... if you did a sketch, it was all clearer and it was just less than half the text. the only description, at least to me, has not made the idea of how the plug works.

if you break the plug connecting rod and punch what does it have to do with how much load can the shaft support?

Thank you.
He's totally right tomorrow as soon as I can maybe attach a photo...
In fact, I'm worried about the "bows" that would take bearings I think a 300mm diameter shaft has no problems due to the load, always considering the work that must be done in the specific case.

Listen, put a pattern because you have it in mind just as it is done and we can be good in mechanics but if we don't understand how it is... we're not helping.

I don't have any better photos.
practically the safety plug is passing behind the mouth marked by the arrow.
the machine in question is another but the concept of safety plug is the usual, the difference is that this machine has a sleigh operated by pneumatic cylinders and the machine that has the problem is driven by a cam mounted on a tree.

probably someone here knows what you are talking about because, from the photos, he recognized the type of machine; or someone who has more imagination than me and understood....I unfortunately am not part of these two categories.
If you want to do it, take a look at a piece of paper, photograph it with your smartphone and place, and maybe someone else and I can say ours.
otherwise wait for someone who knows the car.

I am unable to represent what we are talking about without going to create more doubts.
thanks for the interest
Maybe tomorrow if I can take some pictures to the whole mechanism.

but can't really make a drawing on salami paper? also hurt, as long as the movements and other info you feel are useful.. .
Hard to think that a sketch would create more doubts...

multivac would know how to respond.

p.s. this can only understand that it has grown to bread and asimov as the undersigned.

as said by others you do not understand anything. by making two quick accounts if you have a ø5 plug and is subject to pure cutting, the maximum applicable cutting force, calculating the average cutting effort and considering that it is in c45, is approximately 7376 n, or about 752kg. How did you calculate 200kg?

The first photo shows a block with a quarry.
the second photo looks like a guide column mold with a 0 white on one of the n brackets that hold down the column....but it does not convince me.of thorns I do not see and I have not yet understood a pipe.
