Abstract：

One useful combined forging process of front and back cover used on the friction press was given on the basis of process analysis on the characteristic of ring forgings and flan forgings.This process used the punch of the upper die to pierce billet for back cover,and the rest billet was used for front cover,which was deformed in the die with the strike of the press.By using this process,we can reduce the labor cost,save the materials,avoid the step for blank,and the structure of the trimming die can be simplified.
