Deep draw and tap to form female thread
Deep draw and tap to form female thread
(OP)
I know it is pretty common to form a boss in sheet metal that is then tapped. For instance in say 1mm thick steel to produce a boss that might be 3-4mm high that is then tapped M3.
I want to use this process to put an M20 female thread into a 10 or 12mm thick plate, achieving around 16mm of thread engagement.
Is it possible?
Cheers,
Ian.

RE: Deep draw and tap to form female thread
What material did you have in mind?
How big a press have you got?

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.
RE: Deep draw and tap to form female thread
Material is just mild steel
I have found some theory in an astm or asme manual but the formulas fall over for such thick material
Would this be design by trial and error? Where do I start?
Thanks
Ian
