摘要
基于半球形板件和模具的几何特征,针对36号低碳钢利用有限元仿真软件(DYNAFORM)建立有限元模型,设计不同参数的方案对半球形板件成形过程中的壁厚进行分析。得出摩擦系数对壁厚的影响规律以及和液室压力加载路径对壁厚的影响规律,减轻和避免传统板件成形过程中产生的起皱和破裂等缺陷,获取了半球形板件充液拉深成形的优化工艺参数,为类似的充液拉深件提供工艺参考。
Based on the geometrical characteristics of the hemispherical plate parts and mould,finite element simulation software(DYNAFORM)is used to establish the finite element model,the thickness of the plate in the hemispherical plate stamping process is analyzed by different process schemes with different parameters.The influence rule of friction coefficient and the influence rule of loading path of fluid chamber pressure on the plate thickness are obtained to reduce and avoid the wrinkling and fracture and other defects in traditional plate forming process.The optimized process parameters of hydromechanical deep drawing for the hemispherical plate are obtained,which provides the technology reference for similar product of hydromechanical deep drawing.
