Abstract：

The door frame of wind power tower is an important component of wind power tower. However, it is difficult to produce by traditional technology of complex technology due to its high dimension precision. A new forging technique was developed based on the current manufacturing equipment, the size and shape of workpiece, and the material characteristics. The primary parameters of forging process were calculated by combining with those relevant formulas during the pre-calculation process, and it was convenient to determine the raw material dimension and manufacturing equipment. Thus, the raw material usage value was reduced by rolling. In verification process, the forming step by mold was numerically analyzed by ANSYS Workbench in the forming by die with pre-compress technique. Furthermore, the plastic deformation was pre-observed, and the pre-pressed shaping dimension and mold size were determined. Thus, a new way of manufacturing is provided for producing in-oval shape with equal cross section.
