| Abstract: |
| The molding principle of large diameter ring is expounded. The new bending machine whose working state could be selected and the structure of bending mould are introduced. The stress distributing state on bending mould is analyzed to find out solution for large diameter ring bending resilience. The problems caused by interface between the new type of bending machine and the mould are solved. |
| Key words: large diameter ring molding principle bending machine resilience the interface between bending mould and machine tool |
