摘要
介绍了调直机械定尺切断的工作原理 ,分析了产生切断误差的原因 ,提出了利用PLC的高速计数器进行测长 ,气动剪切机进行切断 ,用显示装置来完成长度设置、产量设置和产量显示。实验证明 ,该系统具有可靠性高、操作方便、定尺切断精度高等特点。
The operational pr inciple of fixed scale shearing of strai ght adjusting machinery is introduced an d the causes of the shearing error are a nalyzed. The method introduced here is m easuring the length by high speed counte r in PLC, shearing the bar by pneumatic shearer and setting the length and showi ng the productive quantity by display de vice. The experiment shows the system fe atures high reliablilty, ease operation and high accuracy of fixed scale.
