摘要
压铸机是有色金属铸件生产的重要装备,广泛地应用在汽车、摩托车、家电、仪表、电子信息等各行业的制造业中,其压射系统的性能的优劣对压铸件的质量起着决定性的作用。针对卧式冷室压铸机二级压射速度控制工艺技术特点,采用自适应模糊控制技术对二级压射进行控制,通过控制增压阀对增压时间进行控制。采用具有典型二阶过程的电液伺服阀系统进行了仿真研究,仿真结果表明了该方法的有效性。
Die Casting Machine is an important nonferrous metal castings production equipment, widely used in automobiles, motorcycles, appliances, meters, electronic information, and other industries in the manufacturing sector, the performance of injection systems on the merits of the quality of die casting play a decisive role. Directed towards technology features of horizontal cold room die casting machine second stage injection velocity control, using adaptive fuzzy control technology to control second stage injection, by controlling the pressurization valve to control the pressurization time. Electro-hydraulic servo valve system of typical second-order process is adopted to do simulation research, simulation results show the effectivity of the method.
