摘要

The rotary forging of a cartridge bottom is simulated by finite element method with DEFORM TM . The analysis of stress and strain rate results indicates that the deformation conditions and the final geometry of a product are not completely axis symmetrical under the partial loading conditions during the rotary forging operations. It is therefore required to have a few more rotary forging cycles at the end of total feeding to eliminate nonuniformity. The results of simulation show that the optimization of rotary forging process conditions can be achieved to avoid the underfill defect resulting from improper process conditions. This technology can be used to manufacture ring components with thin bottoms by properly controlling the working process and the tooling motion.
