The Application Research Of Electro-Hydraulic Proportional Force Control System Of The Embossing Leveler

Non-ferrous metal lead electrolysis industry has brought the huge boost to the development of national economy, lead cathode piece of roughness effects lead electrolysis efficiency, leveling of embossing machine is an important equipment in lead cathode slice flat industry, but the high accuracy hydraulic pressure control leveling of embossing machine is blank in china. Flattening of the embossing machine is the key to force the control accuracy, which is directly related to the level of accuracy of the lead cathode sheets.With the deepening of the reform and opening up the progress of modern science and technology, also the development of national economy make the non-ferrous metals have a huge demand, lead electrolytic industry also toward intelligent, industrialization, mass field of breakthrough. In the process of industrial production, the displacement control, velocity control and force control system combined with electro-hydraulic proportional control technology in the field of non-ferrous metallurgical industry has a wide range of applications. Force controls the system force precision, related to the quality of the product, the company’s energy consumption and production profits, so the force control accuracy is also put forward higher requirements. In this paper, under the background of the electrolytic production line sets to the development of new domestic lead sheet embossing leveler for the study, in order to improve efficiency and creat green friendly hydraulic straightening technology, combined with the actual production conditions and electro-hydraulic proportional force control technology,leveling mechanism and related systems, do the oretical research to lead plate leveler.Firstly,the article compares the current research leveling technology,at the conclusion leveling technology development at home and abroad on the basis of composition and performance characteristics introduced electro-hydraulic proportional force control system, studied the physical properties of lead sheet and leveler mechanism,try to force the electro-hydraulic proportional control technology applied to research in the field leveler lead tablets.Secondly,according to the needs of the process of electrolysis of lead and lead-embossed sheet leveler actual conditions, using the Inventor software to design mechanical embossing leveler lead sheet structure, drawn the3D model and analyzed the rationality of the structure. Flatness of lead cathode effects lead sheet electrolysis efficiency, related to the production efficiency of the entire lead electrolysis equipment, in-depth fundamental research leveling mechanism and lead sheet on physical performance tests, discussed the main factors affecting the lead sheet flatness also proposed flatness control objectives and force requirements, and designed based on electro-hydraulic proportional force control system of the electro-hydraulic control circuit.Then,this paper analyzes the embossing leveler force control system,using modeling of first the element after the system to establish a mathematical model of the system and using the Matlab software to analysis the dynamics simulation of the system.Finally,in view of the embossing leveler electro-hydraulic proportional force control system has a slow dynamic response, anti-interference and robustness issues using force PID control and fuzzy adaptive PID two control strategies in the electro-hydraulic proportional control system.The system is simulated and analyzed by using Matlab/Simulink simulation tool. It also set up the lifting platform virtual experiment of electro-hydraulic proportional control system, designed the hydraulic control circuit, selected a proportional valve and collected the related experimental data.
