摘要
以平板泡罩包装机的吹塑机构为研究对象,对吹塑机构提出一种凸轮弹簧系统的设计方案.首先通过弹簧的工作状态估算弹簧刚度系数;再通过分析机构的运动规律建立合适的凸轮曲线数学模型,在Solidworks环境下结合Excel精确绘制凸轮的三维实体;然后对吹塑机构装配体模型简化,在ADAMS中建立虚拟样机进行仿真,从而得到位移、速度和加速度曲线.通过分析这三种曲线的规律并结合压力角,证明该机构的设计方案是合理的,已应用于某企业的吹塑机构设计中.
The blow molding mechanism of the flatblister packaging machine is seen as a research object,a new system design of cam and spring for the blow molding mechanism. First, to select appropriate spring stiffness coefficient through the spring working condition; Again establish proper cam curve mathematical model through the motion analysis of mechanism, and 3D of cam is drew preeisly combined with Excel in Solidworks environ-ment,then the assemble model should be simplified, obtain the curves of displacement, velocity and acceleration by the virtual prototype of ADAMS. The analysis of these curves and the pressure angle show that this design is feasible.
