【摘要】 通过对现有数控转塔冲床控制系统软、硬件的改进与设计,基于工控机(IPC)结合可编程控制器(PLC),开发出一套开放式转塔打字机路径优化控制系统,提出一种IPC与PLC组成的上、下位机的控制模式。闭环系统实时跟踪锁定当前作业信息,将最优路径控制指令传达给下位机;PLC作为运动控制核心部件,主要通过既定程序控制交流伺服系统驱动转塔执行机构,完成X轴、Y轴等快速移动和精确定位,以实现刀塔双向旋转和任意位置就近换刀的功能,达到最优路径打字目的。现场试验表明,应用PLC控制伺服电机实现数控系统点位控制的方法在实际运行中是切实可行的,不仅能满足控制要求,而且对转塔打字路径优化控制效果显著。更多还原

【Abstract】 Based the existing software and hardware of CNC turret punch control system, this project combined the industrial control computer (IPC) and programmable controller (PLC), developed a set of open turret typewriter path optimization control system, and put forward a kind of IPC-PLC composition control model for a machine. In this control model, the IPC machine is an intelligent command center and the current operation information will be processed through a closed loop system, and the optimal path control instructions will be transferred to the down place machine; since the PLC is one of the core control components in this model, the ac servo system will drive actuating mechanism through a established procedure to complete the fast movement and accurate location of X and Y axis, realize the bi-directional rotation of knife tower, and at any position come near to change the tools function. Eventually the typing path of optimal control purpose could be accomplished. Field test shows that the PLC control servo motor could realize the numerical position control in the actual operation and can satisfy the control requirements, and the simulation of tower type path optimization control effect is remarkable.更多还原
