thermal expansion

[Er Presidente]

If you warm it up slowly, it's better.
If you precision, you have to work at the working temperature, it'll be cold.

However if you can, stabilizing it and working it. But as you say, a little tolerance takes us.

If you warm it up slowly, it's better.
If you precision, you have to work at the working temperature, it'll be cold.

That's right what I meant. .

but do you have to stamp with the ink that drools you, or do you have to punch?
because in the first case, always that you remain parallel to me and not back, the force may be negligible, but in the second after some cycle to 600° throw away everything that has bent you.
Don't you want to study a nice vertical punch that can be extended to you? for elongation recovery you put a nice mollion and you're good.

At this point learned that the stamp "smarts" according to you it is possible to play with the elasticity of the bow to make sure that under effort the bow deforms that much that is enough to put the timbre back on or would break the bow?

working conditions are a tempering range from 300° to 500° with 160 "cuts" per second


to give you an idea of the size the square that stamps is 25mm x 25mm and between a stamping and the other the wheel piece of 45° around the central prey

Wow... I don't mean baggianate, but:
- did you consider the 41n centrifugal force (considering trapeze speed)?
Did you consider the oscillations given by acceleration and braking?
Did you consider creep and subsequent plastic deformation? or use cast iron? in this case, did you consider its fragility and the scarce resilience?
Did you consider that with such a wide range, what is worth an extreme is not worth the opposite?
- did you consider using an articulated quadrilateral instead of a single piece structure?
Have you considered better than using a vertical punch?

Look that the performance you're asking is not really bruscolini, the thermal expansion seems to me the least of the problems, and anyway, sorry, but rest of my idea that the angle doesn't increase... I can't understand why it should increase. . .

I noticed only now that I made a tide of typing errors, obviously I was in dyslexic state.


Unfortunately, it's a "retrofit" that I wanted to do to an existing plant and the only way to get into the machine is to use a piece of that shape, a vertical punch would have been much easier.:frown:



- for the speed of stamping I solved the problem somewhere else and now it only takes 60 stamps per second

- This could be a problem, but I can control them pretty well.

- if the steel is not good I am authorized to use everything .. also titanium:biggrin:

- that's why I need a configuration as much as possible "invariant" towards temperature

- I have no idea how to lubricate the joints at that temperature



if something comes to mind

Hello everyone
I'm new and I don't know if I can move well in the forum
for the timbre in question because you don't create a snout on the timber plate
and with two springs maybe isolated to resent less than the heat do you always stay perpendicular '
I don't know if I was clear.
Excuse me but I write with a finger and looking at the keyboard
anyway good year to all
