100T液压机液压执行机构系统设计.docx

摘要

对四柱型液压机的设计，四柱液压机主机由梁，柱，表，动梁，主缸，顶出缸，如主机设计最大工作负荷为1000000牛。通过液压缸的负载变化情况分析，制定液压系统原理图，对电磁铁的工作。主液压缸的设计，主要的尺寸和流量计算，主缸的交换控制行程开关、平安极限速度的旅行。根据技术要求和液压泵的设计计算选择液压元件，如6￡系列电磁阀。通过液压系统压力损失和温升计算，液压系统的设计可以满足液压顺序循环的要求，四柱液压机的设计可以实现塑性材料的锻造，冲压，冷挤压，矫直，弯曲成形工艺。用于液压系统的PLC控制系统，通过泵和油缸及各种液压阀实现能量的转换，调节和输送，完成各种工艺动作的循环。

水工结构紧凑，可靠的灵敏度和动作速度，能耗小，噪音低，压力和行程可在规定的范围内调整，操作简单。
