摘要
目的研究十字轴闭塞式单向温挤压成形的可行性。方法根据十字轴的结构特点,确定了成形方案,并利用有限元技术对成形过程进行了数值模拟分析,然后结合物理实验对工艺可行性进行了验证。结果有限元分析和试验结果相吻合,锻件成形效果较好,没有出现充不满、折叠缺陷。结论采用闭塞式单向温挤压成形工艺,获得了满足尺寸要求的十字轴锻件,成形过程稳定可靠,成形工艺可行。
The aim of this work was to study the feasibility of cross shaft forging by unidirectional warm extrusion. According to the structural characteristics of the cross shaft,the forming program was defined,and finite element technique was used to perform numerical simulation for the forming process,then the feasibility of the process was validated by combining with physical experiments. The experimental results were consistent with the finite element analysis,showing that the forming was good,without any unfulfilled defects and folding defects. In conclusion,cross shaft meeting the dimensional requirements was obtained by closed unidirectional warm extrusion forming process. The forming process was stable and reliable,and the forming technology was feasible.
