摘要：

为提高平顶链链板精度和生产效率，根据平顶链链板冲压成形工艺，以及生产效率要求，设计了一套多工位自动冲压成形系统，其中包括冲压模具结构设计以及送料系统设计。冲压模具结构设计包括预弯模具、折弯模具以及卷圆模具的结构设计，并利用ABAQUS有限元分析软件进行冲压模拟仿真，改进模具尺寸，提高链板成形精度。送料系统设计包括储料装置、自动送料装置结构设计及相关设备选型。为了实现自动化冲压生产，自动送料装置采用的是三自由度横杆式结构。最后,完成了样机制作和实验，试生产出的平顶链链板合格率达到97.83％，生产效率达每分钟9件，结果表明，所设计的平顶链链板自动冲压成形系统达到了链板的生产精度和生产效率要求。

In order to improve the accuracy and production efficiency of flat top chain plate, according to the stamping process and production efficiency requirements of flat top chain plate, a multi-station automatic stamping system was designed, including the design of stamping die structure and feeding system, and the design of stamping die structure included the structural design of pre-bending die, bending die and rolling die. Then, the stamping simulation was carried out by finite element analysis software ABAQUS to improve the die size and the forming accuracy of chain plate, and the design of feeding system included the structural design of storage device, automatic feeding device and selection of related equipment. In order to realize the automatic stamping production, the automatic feeding device adopted a three-degree-of-freedom cross-bar structure. Furthermore, the prototype production and experiments were completed, the qualified rate of the trial produced flat top chain plate reached 97.83%, and the production efficiency reached nine pieces per minute. The result shows that the designed automatic stamping system for flat top chain plate meets the production accuracy and production efficiency requirements of chain plate.
