Paper Title:
Research on the Blank Selection in the Power Spinning Process of Parts with Transverse Inner Rib
  Abstract

The advent of high-strength and high-precision thin-walled parts with inner ribs adapts to the increasing demand of aerospace industry, astronautics industry, military industry, and so on. For a new metal forming technology, how to determine the reasonable blank is a key problem required solved firstly in the research of power spinning process of parts with transverse inner rib. In this paper, based on the platform ABAQUS/Explicit, a reasonable 3D FE model for power spinning of parts with transverse inner rib has been established, the power spinning process of parts with transverse inner rib has been simulated under conditions of four typical blanks and the reasonable blanks for different forming processes have been obtained. The results show the following:(1) Blank with equal half-cone angle is the best selection to deform workpiece with proper height rib; (2) while for the workpiece with excessive height rib which exceed the forming limit, blank with rib is the exclusive selection, although it is difficult to be prepared comparing with non-rib blank.
