基于DYNAFORM的冲压件坯料尺寸精确计算

Accurate Calculation of Stamping Part Expanded Dimension Based on DYNAFORM Software

以一冲压件(测试件)为例,进行冲压工艺分析后,对冲压件建立三维曲面模型,然后导入DYNAFORM软件进行坯料尺寸计算,得到坯料外形图,将坯料有限元网格化后,再利用DYNAFORM软件的测量功能得到具体尺寸,经实践验证这种方法得到的尺寸十分精确,给模具的设计与制造带来极大方便。

The authors use Pro/E software to make up the three dimension model, and input it into DYNAFORM software to computer the expanded dimension, then get the outline of blank, put the outline into sizing grid, and make use of the measure function of DYNAFORM software to get the dimensions. This method is very accurate by practice, and this accurate dimension is propitious to the design and manufacturing of mould.
