杆系柔性成形模具凸模接触点的计算方法

杆系柔性成形模具是一种成本低、柔性高、生产周期短的板材成形新方法,各个凸模伸缩量的计算是杆系柔性成形模具要解决的基本问题之一。为了实现对曲面板件冲压成形模具的快速重构,针对板件的三维曲面模型,提出了基于STL文件格式的一种简单、实用的离散球形凸模与板件接触点的计算方法,为杆系柔性成形模具的数字化重构提供了一种理论依据。经验证,该方法能够满足模具快速重构的要求。

Calculation of punch contact points in poles flexible forming die

Poles flexible forming die is a new sheet metal forming technology with of low cost,high flexibility and short production cycle.And one basic problem is the calculation of the lengths of all punches.In order to realize the rapid reconfiguration of sheet metal stamping die,a simple and practical method based on STL file format was proposed to calculate contact points and lengths of discrete ball-ended punches in poles flexible forming die.This method has provided a theoretical basis for digital reconfigurati...
