摘要
拉杆是注塑机提供合模力的重要构件。这里用有限元法对拉杆进行了有限元分析,并对拉杆的关键部位进行了材料力学测试,表明拉杆螺纹处的应力集中现象比较明显,并在此部位容易形成裂纹。测试和计算结果可为注塑机拉杆结构的改进设计提供参考。
The pull - rods are important components of an injection machine. In this paper, a pull - rod has been calculated and analyzed by finite analysis method, and the key parts have been tested by material mechanics method. The result shows there is very obvious stress concentration phenomenon in screws, where it is easy to form cracks. The experiment and calculation results will help to optimize the pull - roid screw shape of injecting machine.
