大型台阶圆环锻造技术研究

The Technical Research for the Heavy Duty Stepped Ring Forging

介绍了大型台阶环自由锻工艺参数的确定方法。指出坯料分配是工艺参数中的关键 ,大小台阶的扩孔次序和压下量是控制尺寸精度的重要因素。介绍了锻造大型台阶环的改进工艺 ,用该工艺进行生产不仅节省了原材料 。

The definition of the free forging process parameter for the heavy duty stepped ring forging has been described in this article, which indicates that the distribution of the blank material is the key point for the process parameter, the sequence of the hole enlargement and the press down quantity for the steps are the important factor for controlling the dimension accuracy. Manufacturing with this process will not only save the raw material but also increase the inner quality of the forging.
