Abstract：

The front/rear interface ring whose material is 0Cr17Ni4Cu4Nb with cylindrical，small diameter, sidewall with flange, has a complex structure and is difficult to process and form. By changing the conventional forming method, the front and rear interface ring parts were combined into a whole process including multiple stretching and the integral flanging. Its forming method was simulated by simulation software, verified by experiments and the research results were applied to the actual process. After many trials，the application of the above integral forming technology could improve the forming precision of parts, reduce the number of welds, effectively promote the passing rate of parts, which made the parts achieve the same manufacturing level as the foreign one, finally，the product met the design requirement was obtained.
