摘要
为了提高冲压加工生产效率,改进压力机与送料机之间静态配合的局限性,提出一种压力机与送料机工作周期相互重叠协调控制的解决方案。多工位传递模送料机的水平轴和垂直轴均采用伺服电机驱动,并采用基于PC的控制器实现送料机的多轴运动控制;在送料机和压力机之间采用Ether CAT总线进行通信,并在两者之间进行协调控制实现工作周期的重叠;构建实验装置进行协调控制实验。实验结果表明:与静态配合相比,采用工作周期重叠协调控制后,单个送料冲压工作周期从6. 23 s缩短到5. 76 s,生产效率提高了8. 2%。
In order to enhance production efficiencies in stamping process and improve limitations of static fitting between press and feeding manipulator,a solution based on coordination control with work cycle overlap was proposed.Servo motors were adopted in horizontal and vertical axis of feeding manipulator,and a PC-based controller was used to realize the multi axis motion control.The EtherCAT bus was applied to link the communication between the press and feeding manipulator,for coordination control with work cycle overlap.An experimental setting was made and the coordination control test was conducted.The results show that the new working period is cut down from 6.23 s to 5.76 s and the production efficiency is increased by 8.2%,when compared to the traditional static fit method.
