摘要
目的研究东基集团热冲压生产线的余热回收传送链上的平衡翼在换热器下工作的温度场变化规律,解决平衡翼高温及受载情况下的变形问题.方法利用Pro/Engineer快速建立平衡翼的几何模型,应用Pro/Mechnica的Thermal模块设定边界条件模拟得出筒形体与平衡翼热传导下的平衡翼温度场云纹图,再应用Pro/Mechnica的Structure模块分析平衡翼在温度场云纹图中最高温度下工作时受筒形体重量影响的形变规律,得到其形变图.结果通过Pro/Mechnica分析,在平衡翼温度场云纹图中模拟得出的最高温度为867℃,其出现在底部的销钉槽处.平衡翼在此高温下工作的最大变形量为1.526 mm,形变率为1.38%,不影响其正常工作.结论应用Pro/Mechnica模拟滚子链的平衡翼温度场及其应变变化规律,可以简化计算的数学模型和减少试验验证的工作量,并为制造工艺和控制工艺提供有价值的参数和数学模型.
The temperature field and deformations of the flybar under hot stamping line transmission chain of waste heat recovery in DongJi group were studied. Firstly the flybar geometric model was built by Pro/Engineer. Then the equilibrium temperature moire figure of heat conduction between the fiybar and the cylinder body was simulated by the thermal module of Pro/Mechnica. De-formation rules of the flybar were studied by Pro/Mechnica with the cylinder body weight under the highest temperature and deformation figures were obtained. It is found that the highest temperature 867℃ is on the bottom of the pin tank. The maximum deformation of the flybar under the high temperature is 1. 526mm with deformation rate 1.38%, which can not effect working functions. Conclusion is that using Pro/Mechnica, the temperature field of the flybar and its deformations can be accurately simulated, which can replace complicated calculations and repeating trials and provide valuable parameters and a mathematical model for the manufacturing and control process.
