Four Axizl Precision Flexible Mill Screwdown System Analysis

Based on the comprehensive analysis of research and production of traditional steel mill, this paper studies the new type of flexible precision rolling mill, which can effectively improve the production efficiency, save the investment cost of the equipment, reduce the amount of roll and roll, and improve the product dimension precision and added value.In order to improve the system theory(including the theory of electric system and hydraulic pressure system), this paper studies the design of AGC(automatic control system) and hydraulic pressure of the four axis precision flexible rolling mill. The main parameters are calculated by using theoretical calculation. Then, the control accuracy is low, and the control precision is high, and the reference power system is controlled by the finite element analysis software ANSYS. Control theory, a hydraulic pressure system, which can be applied to the practical application, is designed for the four axis and two way adjustable precision flexible rolling mill.The research of hydraulic pressure AGC system is the design of hydraulic pressure system of AGC system, and the design of hydraulic cylinder and hydraulic press AGC control system, SIMLINK simulation analysis, hydraulic cylinder design and finite analysis, the hydraulic cylinder control accuracy is higher than that of hydraulic pressure mechanism and hydraulic pressure mechanism analysis.The hydraulic pressure system model is developed and the model is feasible. The dynamic setting control theory is used to adjust the parameters of the genetic algorithm to obtain a satisfactory dynamic regulation performance..
