This article analyzes the structure and process of MT-3 draft gear center wedge,deals with the blank-making of fork-type forgings and optimization of the pre-forging structure of forgings with thin walls and high ribs.

Through the analysis and study of the specifications for the forked type forgings,this article has set forth the required method to ensure the low temperature impact toughness of the forked type forgings from the aspects of processes of melting,forging and heat treatment.

The forging method with horizontal V-shaped anvils(HVA) was introduced to control fibrous tissue flow direction,to improve the anisotropy of mechanical properties of axial forgings.

The forging method with horizontal V-shaped anvil were used to control fibrous tissue flow direction,to improve the anisotropy of mechanical properties of axial forgings,to realize uniform forging,resulting in the unique effects that conventional forging methods can not lead to.

Heavy axial forgings made by conventional methods have fibrous tissue, whose direction is parallel to their axes, leading to the anisotropy of mechanical properties.

One useful combined forging process of front and back cover used on the friction press was given on the basis of process analysis on the characteristic of ring forgings and flan forgings.
