Abstract：

The plate forging process of cylindrical part with flange features at the end was put forward to solve the problems such as large forming processing load being in the existing forming process. Then, based on finite element simulation, the deformation process of plate forging process with flange features at the end was analyzed, and the influence laws of sheet thickness, shear amount, height of the area to be deformed and friction conditions of forming interface on formability of flange features were investigated. The results show that the established finite element model can better predict plate forging forming of flange features, and the shear stress dominates the peeling process of metal to be deformed and the body of cylindrical blank, and at the end of forming, the punch upsets this part of metal to form the flange features. In addition, the larger the plate thickness is, the stronger the anti-buckling instability of the cylindrical blank is, and the greater the height critical value of the cylinder wall to be formed. Finally, the radial dimension of the flange feature is positively related to the shear amount and the height of the area of cylinder wall to be deformed, and the differentiate friction conditions of the forming interface can be useful to improve the formability of flange features.
