压印机入口坯饼柔性分散机构的开发研究

Blank Dispersing Mechanism for Stamping Machine

针对压印机在生产过程中出现的坯饼团聚问题,开发了一种利用弹簧为搅拌元件的柔性分散机构,通过竖直悬挂的若干个弹簧对硬币的弹拨作用,实现坯饼的有效分散功能。通过力学建模,建立了这种柔性分散机构的碰撞分离模型以及弹簧尺寸参数的优化模型,结合一个压印机的具体结构参数,采用惩罚函数法(SUMT)对优化模型进行了数值模拟优化,得到分散机构工作弹簧的最佳尺寸参数,实验证明该分散机构具有良好的分散效果。

Stacking blank in stamping machine was studied and a blank dispersing mechanism using springs hanged above the stacking blank to disperse was developed.The model of the collision between the blank and the spring was established through the mechanical analysis.Based on the collision model,the optimized model for selecting spring was established,and on the basis of the parameters of a stamping machine,the SUMT was used to numerically calculate the optimized model and the optimum parameters of the spring which was used in the dispersing mechanism were obtained.The developed blank dispersing mechanism was proved to work well through experiment.
