本文通过分析护角机追切的工作原理、生产流程及切割精度,提出了运控PSDP系列伺服内嵌PLC系统在护角机上的解决方案。方案解决了启动抖动,切割时速度同步难,切割精度差,切割堵刀,返回速度慢等问题,实现平稳启动,追切下刀时同步速度稳定,返回速度快,提高切割精度,切割不堵刀,控制灵活方便,提高了系统生产效率,节省了生产成本。 In this paper, by analyzing the working principle, production flow and cutting precision of the machine, the paper presents the solution to the operation and control of the PSDP series servo embedded PLC system on the corner protector. Program to solve the start jitter, cutting speed synchronization is difficult, poor cutting accuracy, cutting the knife, the return speed is slow and so on, to achieve a smooth start, chase cutting knife synchronous speed stability, return speed, improve cutting accuracy, cutting is not blocked Knife, flexible control, improve the system production efficiency, saving production costs.
