Abstract：

The numerical simulation of stretching process of axle forgings which studied on different types of arc anvils was carried out by Deform-3D professional forging simulation software. The influences of anvil types on the efficiency of stretching with arc anvil were analyzed. The results show that both of the efficiency of stretching with arc anvil and the maximum forging force increase as the arc radius of arc anvil decreases and the central angle increases. Under the same condition, lower tonnage is required for the equipment when stretching by the arc anvil with the preforming part than stretching by ordinary arc anvil. Stretching by the arc anvil with the preforming part not only can keep high efficiency of stretching, but also has a wider range of application.
