中文摘要：针对镁合金电动螺丝刀刀把零件，设计了等温挤压成形工艺和等温挤压试验模具；利用DEFORM-3D对成形过程进行数值模拟，预测了电动螺丝刀刀把零件成形力为250 kN。采用YAW-500kN微机控制电液伺服压力试验机进行挤压试验，试验证明所设计的成形方案合理可行，同时也验证了数值模拟分析的正确性。
英文摘要：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 correctness of the simulation analysis were verified by the experiment.
