针对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。并利用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-500 kN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。 For the electric screwdriver knife parts, design isothermal extrusion forming process and isothermal extrusion test mold. Deform-3D was used to simulate the forming process. The forming force of the electric screwdriver was predicted to be 250 kN. The YAW-500 kN microcomputer-controlled electro-hydraulic servo pressure testing machine was used to carry out the extrusion test. The test proves that the designed forming scheme is reasonable and feasible, and the correctness of the numerical simulation is verified.
