| Abstract: | The academic analyse and finite element simulation are testified by these experiments. The mould and process are optimized by finite element simulation and the result is carried out by trials. The defect is analyzed in cold forming of miniature fastener. The factors of influencing quality of product are discussed in cold forming. The primary material defects,such as fracture and fold,are analyzed by metallurgical. The pre-forming of screw is proposed and the new design of tooling and process to eliminate material folding is obtained. The generic conclusion for the occurrence and elimination of material folding is gained. |
