对称肘杆伺服压力机运动控制器研究

Research and Implement of Motion Control Technologies for Symmetric-Knuckle Servo Press

伺服压力机是传统的机械部分和伺服控制系统的结合,其运动输出可控、生产高效、精度高、噪音低,在各个加工行业中都有广泛的应用。但由于压力机的滑块运动曲线不是恒定的正弦曲线,因此需要针对工件加工的工艺要求对滑块的位置进行标定和对工艺曲线进行相应的拟合与优化。针对此问题,设计了一种对称肘杆伺服压力机控制系统,以此来满足其运动控制功能和性能需求。经过仿真和实验结构表明,该设计可以更好的提高生产效率和加工精度,并且在生产过程中能够很灵活的运用。

The servo press,which is the combination of traditional mechanical part and servo control system,is widely used in industries for its advantages of motion flexibility,high production efficiency,high precision and low noise. Since the movement curve of the press slide is not a constant sinusoidal,it should be designed and optimized in accordance with positioning and technical curve-fitting. Thus,motion control technologies are studied and implemented to meet the control demands for symmetric-knuckle servo press. The design can better improve the production efficiency and machining accuracy,and can be used flexibly in the production process.
