| 摘要: | 橡胶硫化完成后, 模具翻转一定的角度可以便于工人取出橡胶制品和清理模具. 为实现中小型模具翻转, 降低劳动强度, 提高生产率, 研究一种180°模具自动翻转机构, 采用SolidWorks建立该机构的三维模型, 并在其motion模块中进行运动学仿真, 得到模具的运动特点. 对翻转机构进行优化分析, 以滑轨宽度为90mm, 限位沟槽宽度为20mm, 求得曲率半径为37mm时, 模具的角加速度最小, 翻转运动最为平稳; 运用有限元软件ANSYS获得翻转设备在极限载荷工作时, 主要受力件固定轴的应力场. 制成样机并经实际应用表明, 设计的翻转机构运行平稳可靠、易于控制, 能更好地满足实际生产要求. |
| Abstract: | After the rubber vulcanization is completed, the mold is usually turned over to a certain angle in order to take out the rubber products and clean the mold. For the small and medium mold, a new type of 180° mold automatic turnover mechanism is proposed to decrease labor intensity and increase production rate. The 3D model of the mechanism is established using SolidWorks software. In addition, the movement characteristics of the mold are obtained by carrying out kinematic simulation with the motion module of SolidWorks. Through optimization, it is found that the angular acceleration of the mold is the smallest and the turnover is the most stable when the curvature radius is 37mm under the condition that the slide width is 90mm and the limit groove width is 20mm. The stress field of the main bearing part is obtained by the finite element software ANSYS when the turning device is working under the ultimate load. The prototype has been made and its application shows that the turnover mechanism is stable and reliable, easy to control, and better meeting the practical production requirements. |
