Abstract：

For the problems that the traditional forging process of sector needed complex tooling, large-tonnage steel ingot and more times of forging fire, as well as poor economy and quality risk which was difficult to control, the supporting guide tooling and intermediate frequency induction coil were designed. Forming processes of sector under different materials and shrinkage ratios were studied by the hot-pushed bending process and the ideal effect was abtained. In the hot-pushed bending process, the forming of sector is stable, fast and accurate, the mechanical properties meet requirements, and the required billet tonnage is small, which has great technical and economic advantages. At the same time, the key technological parameters of hot-pushed bending process accumulated in the process research of 1∶6 and 1∶2 sector scaling workpieces can provide technical support for hot-push bending of 1∶1 full-size sector scaling workpiece, which provides a new way for forming of finished sector products.
