| 为实现异形热成型包装件的准确分切，研究异形新型裁切工艺过程与仿形裁切机构。通过分析异形包装件的外形轮廓和裁切要求，确定了裁切的工艺过程和裁切刀的运动轨迹。选定相应的执行机构,并对仿形裁切机构进行参数化设计。采用可实现运动轨迹的凸轮 连杆机构带动裁切刀进行仿形裁切；采用解析法对执行机构进行参数化分析计算，找到固定凸轮与连杆的几何关系，最终确定执行机构关键部件固定凸轮的外形轮廓。采用仿形裁切方法可以实现异形热成型包装件的有效分切，本研究可为异形件裁切系统的设计提供参考。 |

| Taking Special shaped thermoformed packages as the research object, the new cutting process and cutting device of special shaped thermoformed packages were studied in this paper. By analyzing the contour and cutting requirements of the thermoformed packages, the cutting process and the trajectory of the cutting blades were determined. The corresponding actuators were selected, and the profile cutting mechanism was parameterized. Cam link mechanism which could realize the movement track was used to drive the cutting knife to make profile cutting. The analytic method was used to analyze the parameters of the actuator, and the geometrical relationship between the fixed cam and the link were found. Finally, the outline of the key parts of the actuator fixed cam was determined. The profiled cutting method could effectively cut the special shaped thermoformed packages, which provided a reference for the design of the special shaped cutting system. |
