Continental forgings are important parts on American cotton harvesters. They are of large space dimension change,complex shape, strictly-controlled in inspection, and fash needing to be put in two sides of forgings technologically, that is,  die parting face must be S-shape. Based on the actual manufacturing equipment, part dimension and shape characteristic，the analysis of forgings was carried out, the reasonable forging process was made, and the forging dies with convenient installation and high efficiency production were developed, which realized the forging forming of continental forgings and was recognized by customers and achieved batch production. Verified by production，the forging parts are of high precision，the forming effect is good, the consistency of forging dimension and quality is excellent, and the requirement of forgings detection is met.
