| Abstract: | The electric upsetting forging process for the stress bolt in series 150 and 396 high-power high-speed diesel engines was researched. The key points in design of the forg- ing die were presented and several computational formulas for the physical dimension were given. An effective method to ensure the precision of electric upsetting forging pro- cess was proposed. |
