等面积法确定翻边预冲孔直径

Confirmation of the Diameter of the Pre-punching Hole in the Turning up Plate by Using Equal Area Calculation

介绍了钢板翻边工艺中预冲孔直径的等面积计算与工艺验证结合的确定方法。采用这种方法 ,可以保证翻边成形后工件的尺寸要求 ,对于精度高。

This paper introduced the method to confirm the combination of the equal area calculation of the pre punching hole in the technology of the turn over of steel plate.Adopting this method the size of the work piece after being shaped can be guaranted.It is also very meaningful for the processing of the products in high precision and with big batch.
