摘要
建立了精冲挤压变形区的力学模型,提出了精冲挤压材料流动规律及控制原理;通过实验和测试分析了三维精冲件变形截面的金属流线和显微硬度分布;最后用DEFORM软件分析了精冲挤压的成形过程并进行了参数优化。
Mechanics model of the fineblanking-extruding deforming is built,the flowing rule and controling methods of fineblanking-extruding are also provided;streamlines and microhardness of the fineblanking part are analyzed by experiments and measuring;precess of fineblanking-extruding is opti-mized from parameter by Deform.
