Stability Regulation in Control System of a Large Strong Vertical NC Spinning Machine |

| Abstract: | This equipment is a large vertical three-roller powerful CNC spinning machines.It uses closed solid frame structure,consisting mainly processing thin wall barrel structure.Rough materias are ultra-high strength steel,stainless steel and nonferrous metals.Design requirement is that the radial maximum thrust of rotating wheel seal is 500kN/wheel,the axial maximum thrust is 333kN/wheel.The axial coordinate stroke of the machine is 1600mm.The radial and axial positioning accuracies are 0.02mm and 0.04mm.Large tonnage,length stroke,high position precision are the characteristics of the spinning machine.The control system uses the full closed loop control mode hydraulically driven by CNC system in the control system.This article discusses the proportional servo valves of the high frequency response controlled by Siemens 840D CNC system and Siemens hydraulic driven module are used to adjust the stability driven by the asymmetric hydraulic cylinder in large vertical spinning machine. |
