To choose the process of precision forging is to replace the traditional casting scheme.The paper analyses the forging process of 280 diesel engine rocker shaft bed part and introduces the computing technology of high-energy screw press nominal pressure value.In designing the process and die,Pro/E 3-dimensional modeling method is adopted to replace the traditional die design and manufacture with CAD/CAM technology and it has realized no drawing die design and manufacture.It tries to realize precision forging without less or no oxidation heating equipment and upgrade the level of process,die designing and manufacturing,product dimension precision and productivity.The synthesis mechanical properties are greatly improved compared with that of casting scheme.Successful development of the process solves the crack problem of the Rocker shaft bed,guarantees the normal test & work of the 280 diesel engine and enhances the reliability of the diesel engine.The process is an originated and advanced technology in the railway factory of our country.It is proved by production practice that the design of process and die is reasonable and product quality meets the designing requirement.
