Abstract：

The forged knuckle is a kind of common drawing components used for couplers of railway wagons. The product has various sections，complicated shape and thin rib, which is difficult to form. According to the characters of forged knuckles, the process schemes were developed and draft angle and radius were optimized. The folding defect was simulated and the solutions were presented. Further, the forging dies were designed based on optimized technical process. Finally, the practical test shows that the parts of volume product are good.
