Over Bend Deflection on Stainless Steel
Over Bend Deflection on Stainless Steel
(OP)
Hello,
I am looking for an Over Bend Deflection formula for Stainless (.094 thick).
Like if I have a 35deg. bend needed, would I make the bend at 37 deg. such that the deflection it comes back would be 35 deg.
Any info or experience on a good starting point to start with would be great.
The thing is I need to manufacture a punch out of D2 56-58 Rc for form this bend for a customer and then put it into their machine with minimum down time … so I really need to get it right the first time.
Thanks for any who share.
Luke

Can you get any information from the material supplier? Failing that 1-2 degrees over top limit is probably a reasonable place to start, you should at least minimise the amount of rework required.
Also use the press you will use in production if possible.

I really do not have the Luxury to test before making the Punch/Die. Getting it close for starters and then reworking sounds like the best solution in this case. I was hoping someone on this forum might have had some experience on working with this type of work before and has seen a characteristic in about what it would take to make a very close bend without testing.
Thanks again,
Luke
