作者根据起停式角钢飞剪的剪切工艺要求,研制出一种新型的起停式飞剪的直流控制系统。该系统能够逻辑控制剪刃的运行规律,保证剪刃线速度与轧件线速度同步,保证剪切产品长度的定尺精度。本文介绍这种新型的起停式角钢飞剪直流控制系统的结构及控制思想,重点论述了保证同步及定尺精度的措施。
According to the requirements of shearing technology of start-stop angle shears, a new DC control system of start-stop shears was developed. The system can logically control the cutting edge of the law of operation to ensure that the cutting edge line speed and rolling line speed synchronization to ensure the length of the cut product length accuracy. This article describes the structure of this new type of start-stop angle steel flying shear DC control system and its control philosophy, focusing on the measures to ensure synchronization and length accuracy.
