摘要
考虑到薄板冲裁板料厚度的特殊性,运用Deform-2D软件,构建了料厚为0.1 mm的薄板有限元模型,通过模拟薄板切断面的形成过程,分析了不同模具间隙下冲裁件的断面质量及温度变化,并在此基础上对冲裁中模具磨损进行理论预测,为生产中选择合适的工艺参数,规范模具更换周期,进而优化模具结构具有重要意义。
Considering the particularity of sheet thickness in sheet blanking,buih the finite element model of plate thickness of 0.1 mm in using software Deform-2D. The article analyzes section quality and temperature changing of the blanking pieces under different mold clearance by simulating forming process of cuting off the plate. And on the basis of it,the paper has a theory predict on mould wear in blanking.h has a great significance of choosing the appropriate process parameters for the production, specificating mould replacement cycle and optimizing the mould structure.
