摘要
多排链轮结构复杂,采用锻造成形比较困难。本文以某型号四排链轮作为研究对象,模拟分析了坯料在锻模中的流动分布规律、应力分布规律,以及模具的应力分布和载荷分布规律。结果表明,链轮锻件的整体流速较均匀,填充情况较好;锻件的应力分布较均匀,离散程度较低;锻造载荷值逐步上升,没有出现突变的现象,载荷最大值为2119.69 kN。
The structure of multi-row sprocket is complex, so it is difficult to form by forging. Taking a certain type of four-row sprocket as the research object, the flow distribution and stress distribution of the blank and stress distribution in die,load distribution were simulated and analyzed. The results show that the flow velocity of sprocket forging is uniform and the filling condition is better;the stress distribution of the forging is uniform and the dispersion degree is lower;the value of forging load increases gradually, and there is no sudden change. The maximum value of load is 2119.69 kN.
