| Abstract: | The isothermal extrusion process and dies for electric screwdriver hilt were designed.The deformation process was simulated by using finite element software DEFORM-3D.The formation force of electric screwdriver hilt predicted was 250 kN.The isothermal extrusion was done by pressure machine YAW-500 kN.The rationality of deformation project and correculess of the simulation analysis were verified by the experiment. |
