Abstract：

For cushion segment in the disc assembly of automobile clutch, a calculation method of forming height for cushion segment was presented based on the analysis of the springback theory, which is called reverse trial method. Then, the dimension of forming die for cushion segment was obtained according to the reverse trial method, and the progressive forming die was designed to obtain experimental forming height of 1.71 mm. The results show that the forming height obtained by the reverse trial method is 1.90 mm, and their error is 11.11%. Therefore, the correctness of the reverse trial method is verified. In addition, the cushion segment in the single class output is produced from 9000 pieces to 31000 pieces by progressive forming die. Thus, the die design is guided well, and the production efficiency of enterprises is improved greatly.
