Abstract


Flying shears steel rolling workshop is a common shearing equipment , automatic control certain representation . The modern rod line production rolling speed increasing our existing high-speed wire rod production line maximum exit velocity reached 120m / s . Bound to such high-speed flying shear machine electrical control system proposed increasing demands , that is, flying shears must have fast response, accurate control , the characteristics of the low failure rate . This paper focuses on the Siemens S7-400 PLC and T400 technology board control environment , start and stop flying shears , automatic control system and its implementation . Control and positioning of the cutting edge length of the flying shear control program is designed to complete the design of the PLC peripheral circuits of field I / O configuration ; STEP7 LAD, CFC programming software to write the control system structure completed the flying shear Blade precise positioning and rolling precise shear . System the remote the WINCC monitoring software monitor screen , including the \seven screen design . Flying Shear Blade positioning control PLC-APC position automatic control using Siemens technology board T400 high-speed computing and software instruction given by the deviation of the actual location of a given target detection Flying Shear Blade corresponding a speed command, when the deviation is zero , the velocity output is also zero , to ensure the precise positioning of the cutting edge . Finally, the completion of the work of the Joint reconcile test of the entire system and achieved good results . The system successfully run the test , and fully demonstrates the validity and reliability of the results of this study .
