dear all
I'm going to create a ring with special criteria some pictures of it can be seen here:
- as shown in attached pictures a portion of structure is just an easy cylinder form but the other portion is conical shaped
- it must be seamless, coldworked and made from stainless steel sheet
- thickness of the sheet is 15 mm
- it must be produced with a good telorance ( the bend shape must b axact)
my questions are : which forming process is the best for it?(rolling , spinning , any other forming process? these are just my guesses ) can it be formed in a full ring and then splited into two halves? or residual stresses would not let me do something like this even if I anneal it , and I should form it in a half ring from the begining?
can anybody provide me some information? any kind of information or sugestion would be precious. thanks in advance for your care best regards, Shantia
