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 product.
