单位代码 6030 毕业设计(论文) 小型气动压力机的设计 黄河科技学院毕业设计 第 PAGE \* ROMAN \* MERGEFORMATIV 页 小型气动压力机 摘要 小型号的气动压力机，适用于轴类零件，型材的校正和轴套类零件的压装。它采用手脚联动操作，通过电动机带动气压泵向主油路供气，通过溢流阀，手动换向阀等控制阀对气压系统进行调压换向，以达到各种工作状态。 该气压机结构紧凑，动作灵敏可靠，速度快，能耗小，噪音低，压力和行程可在规定的范围内任意调节，操作简单。在本设计中，通过查阅大量文献资料，设计了液压缸的尺寸，拟订了液压原理图。按压力和流量的大小选择了液压泵，电动机，控制阀，过滤器等气压元件和辅助元件。 关键词：气压机；气压系统；调速往返路 Small pneumatic presses Abstract Single-column adjusting press-assembly hydraulic press is a versatile and the machine parts shall apply to the class, type the correct and the kind of parts of the press. It adopted and winding, by hydraulic motor drives the pump to the principaloil supply, the overflow from the valve stem control valve manual crossover wait for the hydraulic system to a regulated pressure crossover to achieve the state. The hydraulic compact structure, sensitive, speed, energy consumption, low noise, and journeys are within the prescribed scope of any regulation, a simple operation. in the design of information and evidence by reference to design the size of the jug, the drafting of a schematic diagram. by hydraulic pressure and flow of the size of a hydraulic motor pump, filters, etc, control valve, hydraulic components and auxiliary units.
