【摘要】：根据高强度机械零件的锻压工艺要求,设计了梁柱结构模锻压力机的液压系统和PLC控制系统,液压系统采用了基于增压缸的增压回路,降低了系统的压力等级,提高了液压元件的使用寿命。为实现液压缸的快速运行,系统采用差动连接和基于蓄能器的快速运动回路。为降低液压换向时产生的冲击,采用先降压再换向的泄压回路。利用AMESim软件对增压回路和快速运行回路进行仿真分析,系统压强为10.65 MPa,经过增压回路增压后,液压缸内压强为52.46 MPa,符合增压比5.165的设计要求。仿真结果表明,系统具有压力高、动作快、增压效果明显、自动化程度高等优点,满足高强度机械零件的模锻需求。
[Abstract]:The hydraulic system and PLC control system of Liang Zhu structure die forging press are designed according to the requirements of forging technology of high strength mechanical parts. The hydraulic system adopts a pressurized circuit based on pressurized cylinder. The pressure grade of the system is reduced, and the service life of the hydraulic components is increased, so as to realize the rapid operation of the hydraulic cylinder. The system adopts differential connection and fast motion loop based on accumulator to reduce the impact of hydraulic commutation. The pressure relief circuit is first reduced and then reversed. The system pressure is 10.65MPa, and the system pressure is 10.65MPa, which is analyzed by the simulation analysis of the booster circuit and the fast running circuit by using AMESim software. The system is pressurized by the supercharging loop. The pressure in the hydraulic cylinder is 52.46 MPa, which meets the design requirements of the booster ratio 5.165. The simulation results show that the system has the advantages of high pressure, fast action, obvious pressurization effect and high degree of automation. To meet the needs of high strength mechanical parts die forging.
