Abstract：

Die forging technology of center wedge of railway wagon MT-2 draft gear was designed.The part was analyzed and a scheme of forging technology was prepared.The parameters of forging and die were designed.Through trial production,the forging defects of the samples were analyzed.The structure of die flash groove was improved.The problem of overlapping in samples was solved.The results of mass production show that the forging technology is reasonable and effective.The quality can meet the technical requirement.
