Y32-1000T三梁四柱液压机设计 摘要 液压机是一种以液体介质传递能量来实现各种加工工艺的机器。本次设计的液压机是四柱式万能液压机，其主机结构主要包括液压缸，上横梁，活动横梁（滑块），四个立柱，工作台（下横梁）和顶出缸等。通过查阅相关参考文献，对液压机整体进行充分了解，更好的进行方案的分析与选择。 本次设计首先对液压机的主机结构和液压系统方案进行了分析，然后对液压机的主机结构进行了详细的设计计算与校；采用“三梁四柱”式主机结构。 在液压系统的设计中，首先对其进行了负载分析，接下来对液压机的主缸和顶出缸的设计进行了大量阐述，从而绘制出液压系统原理图。又对液压泵、油管、电动机等进行了设计与选择，最后得到对泵站的布置安装。 通过本次设计对液压机进行更深一步的了解，感受机械在生活中带给我们的便利，为促进其发展做出更大的努力。 关键词：四柱液压机；液压系统；液压缸 ABSTRACT Pressure processi
