斜齿轮冷精锻成形工艺方案研究

Study on Method of Cold Precision Forging Helical Gear

在直齿圆柱齿轮冷精密成形研究成功的基础上,将成果推广到斜齿轮冷成形工艺的研究中。借助于三维数值模拟软件Deform-3D的分析,提出了一个试验方案。然后利用双向镦挤工艺,试验出了完好的斜齿轮。最后的结论是,理论分析与实验的结果基本上符合。

On the basis of success studied the cold precision forging spur gear, the fruit was applied to study of cold precision forming the helical gear. By dint of analysis of Deform-3D numerical simulation software, an experimental scheme was put forward. And then employing double direction extrusion upsetting technology, the well-shaped helical gear was obtained in experiment. Finally, the conclusion is that result of theory analysis with experiment is basically consistent.
