Elliptical ring forge piece and forging forming method thereof

The invention discloses a forging forming method of an elliptical ring forge piece, which comprises the following steps of: determining the size of an equivalent circular ring finish blank according to the size of the elliptical ring forge piece to be formed; according to the size of the equivalent circular ring finished blank, the blank is forged into the equivalent circular ring finished blank; forming the equivalent circular ring finished blank into an elliptical ring forge piece by using an elliptical ring forge piece die through multiple times of forging; the oval ring forge piece die comprises an upper die, a lower die and a cushion block. The upper die and the lower die are assembled to form an inner cavity matched with the outer profile of the elliptical ring forge piece to be formed; and the outer molded surface of the cushion block is matched with the inner molded surface of the to-be-formed elliptical ring forge piece. According to the method, the percent of pass of the elliptical ring forgings is
