Zusammenfassung:The invention aims to provide a forming process and die for a long-rod-like die forging with a large round angle. The forming process is characterized by comprising the specific process steps of material calculating, bending die design, a free forging blank making, die forging pre-forming, final bending forming and manual correction. According to the forming process, procedures such as free forging blank making, die forging pre-forming and final bending forming are reasonably adopted, so that the final forming requirement of a forge piece is met, and the overall streamline of the die forging piece is more reasonable. According to the final bending die, a positioning pressing plate is reasonably arranged, and a positioning bolt with the adjustable position is adopted so that accurate positioning of the pre-formed forging piece can be guaranteed, the common problems that the bending position of a large-round-angle part is not fully filled, the forge piece is prone to be broken and damaged, the thickness of the
