Definition

Cross wedge rolling is a forming process for reshaping circular cylindrical billets to plastic rotationally symmetrical workpieces with variable diameter in axial direction using two oppositely moving wedge-shaped tools. While in cross rolling the rolled material is passed through two or more rolls to reduce the overall thickness of the parts, in cross wedge rolling, the wedges of the tools lead to an unequal mass distribution along the main axis. It is mostly used for preforming, but also some shafts are formed entirely by cross wedge rolling. Depending on the tool geometry, three different process variants can be distinguished:
  • Cross wedge rolling with convex curved tools rotating in the same direction

  • Cross wedge rolling with a fixed concave tool and a rotating convex tool

  • Cross wedge rolling with two flat wedge tools linearly moving in opposite directions

The geometry and arrangement of the tools of the three...
