摘 要

液压技术是现代制造的基础，他的广泛应用，很大程度上代替了普通成型加工，全球制造业发生了根本性变化。因此，液压技术的水准、拥有和普及程度，已经成为衡量一个国家综合国力和现代化水平的重要标志。为适合这种行势，需要大量设计一些液压机的工作系统。本次就是要设计一款四柱万能液压系统。液压技术已被世界各国列为优先发展的关键工业技术，成为当代国际间科技竞争的重点。
本书为机械类液压设计说明书，是根据液压设计手册上的设计程序及步骤编写的。本书的主要内容包括：卧式钻镗组合机床液压系统的设计课题及有关参数；工况分析；液压缸工作压力和流量的确定；液压系统图的拟定；驱动电机及液压元件的选择；液压系统主要性能的验算；设计体会；参考文献等。
编写本说明书时，力求符合设计步骤，详细说明了液压系统的设计方法，以及各种参数的具体计算方法，如压力的计算、各种工况负载的计算、液压元件的规格选取等。
本书在编写过程中，得到黄教授和同学的大力支持和帮助，在此一起表示衷心的感谢。
由于编写水平有限，书中难免有缺点和错误之处，恳请老师批评指正。
 谢谢！

Abstract

The liquid presses the technique is the foundation of the modern manufacturing, hi****tensive application, the very big degree ancestors substitutes the commonness to model to process, the global manufacturing industry took place the basic *** variety.Therefore, the liquid presses the technical level, owns and universal degree, have already become measure a national comprehensive national strength and modernization level of marking.In order to suit this kind of line of power, need a great deal of work system that designs some liquids to press the machine.This time is to  design a style four the all-powerful liquid of pillarses press the system.The liquid presses the key industry technique that the technique has already been list as by the international community to have the initiative the development, becoming the point of a science and technology competition.
This book presses to design the manual for the machine liquid, pressing to design the design on the manual procedure and the step plaits to write according to the liquid of.The main contents of this book include:The lie type drills the design topic and relevant parameters that the 镗 combination  tool machine liquid presses the system;The work condition analysis;The liquid presses the assurance of an urn of work pressure and discharges;The liquid presses the draw-up of the system diagram;Drive the choice that the electrical engineering and liquids press the component;The liquid presses the main function of system to check to calculate;The design realize;Reference etc..
When plait write this manual, try hard for to match to design the step, elaborate on the liquid to press the design method of the system, and the concrete calculation method of various parameter, press the specification selection of the component such as the calculation, liquid of calculation, various work  condition load of pressure etc..
This book gets the relevant teacher and classmate to support strongly and help in weave write process, meaning the heartfelt with gratitude together here.
Because the plait writes the level limited, difficult do not need the place of weakness and mistake in the book, plead the teacher the animadversion correct.
 Thanks!
【Key word】  four the all-powerful liquid of pillarses press the machine, the liquid presses the urn, system pressure
