摘要
目的:解决热成型机的核心部件开合模机构相关杆件设计及其分析技术难题.方法:运用解析法阐述了一种热成型机的电动八杆开合模机构的运动和受力分析.结果:基于实例计算得到执行滑块位移与曲柄转角关系曲线,并进一步推导了速度和加速度变化规律;同时还揭示了片材挤压阶段的理论合模力和各杆件受力变化趋势及特点.结论:实现了在不具备专业软件的条件下对电动八杆开合模机构的分析,缩短了设计和试制周期.
Abstract
Objective:To solve the technical problems in the design and analysis of the core parts of the mold open-closing mechanism related rod.Methods:The motion and force analysis of mold open-closing mechanism with an electric eight-bar was described in detail by using the analytical method.Results:Based on the example calculation,the relationship curve between the displacement of the slider and the crank angle was obtained,and the variation law of velocity and acceleration was further deduced.Meanwhile,the theoretical clamping force,the changing trend and the characteristics of each member force in the sheet extrusion process were analyzed.Conclusion:The method solves the implemented analysis of the electric eight-bar linkage mechanism without the need for professional software,shortening the design and prototyping cycles.
