半球形镦头凹模结构参数优化设计

The structure parameter analysis of hemispherical heading die

通过对球头销类零件冷挤压的常用模具半球形镦头凹模的结构参数的分析和优化,得出了半球形镦头凹模最佳尺寸和单层时可以承受的最大单位载荷,为实际模具设计提供了理论依据。

The structure parameters of hemispherical heading die have been analysed and optimized hence dimension and the maximum pressure per unit of area that it can bear have been obtained to provide design of extrusion moulds with theoretical base.
