FORGING RATIO - FLANGES
FORGING RATIO - FLANGES
(OP)
Hi All,
I'm quite familiar with calculating forging ratios, but how is this performed for wn flanges (i.e. items with effectively 2 cross-sectional areas?)
I'm forging a 320mm diameter x 380mm height bar into a flange of body diameter 500mm x 114mm height and neck diameter 265mm x 136mm height.
Would it simply be the original height divisable by the final height? 380/(114+136) = 1.52:1?
Thanks in advance.

Hint - look at the maximum final cross sectional area of the forging.

Cheers!
What I'm getting at is the ratio between heights would oridinarily be the same as the ratio between the cross-section in a uniform cylinder.
In a flange this is not the case, but from what I think you're saying/the links say...
I simply calculate, if upsetting, max cross-section of final divided by initial cross-section?
Regardless of the shape?
Thanks.
