| 摘 要： | 通过对液体火箭发动机所用不锈钢弯管上椭圆预制孔翻边成形圆孔的分析、计算及试验,确定了合理的椭圆孔长轴和短轴尺寸计算公式,给出了翻边力的计算公式．翻边凸模为球形。考虑到回弹的影响,实际长、短轴尺寸要比根据公式计算出的值小一些,球形凸模的直径要比翻边直径大一些。

| Abstract: | Based on the analysis, calculation and testing of circle flanging forming by prefabri- cated elliptical hole in stainless steel elbow for rocket engines, calculation formulas of major and mi- nor axes of the elliptical hole and flanging force were determined. The effective length of elliptical axes was less than that of calculations, whereas the diameter of ball mould was bigger than the hole by taking rebound effect into account. Reasonable design of the die and simple operation ensured high yield of the p... |
