基于SimoDrive 611U/Ue的液压精密控制系统设计与实现

钢管数控成型机是一种通用型高端设备,应用于钢管圆形、方形等内孔成型加工。为了提高成型机液压系统位置控制精度并降低系统能耗,根据成型机工作条件,提出由伺服驱动器、伺服电机、光栅及传感器等构成液压精密控制系统的设计方案。该方案利用伺服驱动器控制伺服电机旋转,带动定量泵控制液压缸位移,光栅反馈位移量给伺服驱动器,构成闭环控制来达到精密控制效果。该设计具有改造费用低、加工效率高和精度高等优点。

Design of Hydraulic Precision Control System Based on SimoDrive 611U/Ue

CNC tube forming machine is a universal type of high-end equipment , applied to steel tube round , square and other inner hole forming processing .In order to improve the position control precision of hydraulic system and reduce the system energy con -sumption, according to the working conditions of the forming machine , the design scheme of hydraulic precision control system com-posed of servo actuator , servo motor , grating and sensor was presented .In the scheme , servo driver was used to control the rotation of the servo motor , driving the displacement of the hydraulic cylinder of the quantitative pump , and the displacement was feed back to the servo drive by the grating , thus a closed loop control was formed to achieve the precision control effect .The design has the advantages of low cost, high processing efficiency and high precision .
