The present invention provides a method of near-net-shape forged molding of the coupler knuckle of the railway vehicle. The present invention solves the problems that the manufacturing the forged coupler knuckle is difficult, and the process is complex, etc. The method of the present invention includes the following steps: material preparation, heating, blank prefabrication, pre-forging, closed-die forging, quenched-tempered heat treatment using waste heat, finish machining, flaw detection, etc. With the closed-die forging technology, the near-net-shape molding of the coupler knuckle can be achieved. The energy and the material are saved. The contour shape and the size do not need to be machined. The use ratio of the material can reach more than 92%. Moreover, during the entire molding, the workpiece is in the three-dimensionally stressed state all the time. The product has a dense texture, a high toughness, a good fatigue resistance, and a long lifetime.
