摘要
本文通过对压力机机械凸轮在各个角度链条断开情况的分析,介绍如何用PLC检测机械凸轮断链条问题,并实现其单次防连冲功能。此外,针对不同型号压力机以及同一型号压力机不同速度段,本文也介绍了如何实现PLC程序的通用性。
By analysis of break cases of chain in different crank angle of the mechanical cams in press,the way to use PLC to check the chain break has been introduced in the text,which guarantees anti continuous strokes in single mode.Besides,the way to design the general PLC controls procedures for different speed range of the same type of press as well as different models of press has been put forward.
