1、摘 要 液压机是一种以液体为工作介质,其系帕斯卡原理制成,是用来传递能量以实现各种工艺的机器。液压机液压传动系统的工作特征是以压力变换为主,其广泛应用于机械工业的许多领域。例如锻压、板料冲压、金属冷挤压、塑料制品、磨料制品、金刚石成形、校正包装、打包、压砖、橡胶注塑成型、海绵钛加工、人造板热压、粉末冶金,乃至炸药模压等十分广泛的不同工业领域。本文先通过工作要求计算出本设计液压机的主要技术规格,而后进行多种四柱式液压机的方案论证比较,选出最优设计方案。根据最优方案模型,依次设计完成本机(主要)、液压系统和泵站。在设计本机时,按递进原则,优先设计出液压缸各项尺寸参数,然后以设计好的尺寸为基础尺寸逐
2、一完成立柱、横梁和工作台的设计和校核。在设计液压系统时,通过参考相关液压机液压原理图,然后分析本设计液压机所要实现的工作要求,分块设计各部分回路系统,将他们联接在一起,组成本设计液压机的液压系统。在进行泵站的设计时,主要完成液压泵与电机的选用和油箱的设计。最后,将设计好的液压机的各部分零、组件组装在一起,完成了液压机的总装。本设计液压机具有独立的动力机构和电气系统,采用按钮集中控制,可实现调整、手动及半自动三种工作方式。液压机的工作压力、压制速度,空载快速下行和减速运行的行程和范围,均可根据工艺需要进行调整。并能完成顶出工艺、可带顶出工艺、拉伸工艺三种工艺方式。每种工艺又有定压,定程两种工艺动
