Abstract：

The long-axis heavy forging workpiece is stretched by V-shaped anvil forging and four-anvil radial forging, etc. In order to understand the influences of stretching methods on deformation in the core of forging workpiece, the stretching process was simulated by the finite element software SuperForm, and the V-shaped anvil forging and four-anvil radial forging were compared from the aspect of forging penetration efficiency. The research results show that the equivalent strain distribution of the internal forging workpiece is uneven with big difference by V-shaped anvil stretching. However, the high forging penetration efficiency in the core of forging workpiece is obtained by three passes stretching, and the cumulative equivalent strain is about 1.6 under the given condition. But, the equivalent strain distribution of the internal forging workpiece is uniform by four-anvil radial forging, the forging penetration efficiency in the core of forging workpiece is bad, and the equivalent strain is less than 0.2 under the given condition. In addition, the equivalent strain in the core of forging workpiece in the end within a certain distance is smaller, and the cumulative equivalent strain is about 0.8 after four passes streching.
