摘 要
液压工业是一个国家的重要产业，液压工业的发展无时不刻都在影响着国家经济的发展，人类的进步离不开液压工业的发展。在全球经济发展的大环境下，中国各个行业被其他国家的先进技术影响的同时，越来越多的外国企业和品牌传播到中国已经成为现实。在新的市场需求的推动下，对DG型液压缸进行改良和优化是当务之急。有大型压管设备企业对设备的安全指标的有着一定生产的严格要求。在生产设备的企业，充分考虑到在设备运行中可能出现的问题，从而减少噪声污染引起的振动或不当操作设备的现象等。国内管套压装专机设备的研发及制造要与全球号召的高效经济、安全稳定主题保持一致。管套压装专机的发展与人类社会的进步和科学技术的水平密切相关。 液压缸是液压系统的最重要的动力元件，它由油压驱动，主要应用在重载荷的场合。整个液压系统的源动力由液压系统中的液压泵提供，齿轮泵、叶片泵和柱塞泵是液压泵的结构形式。液压系统中控制和调节液压、流量和方向的控制元件(即各种液压阀)。控制功能各有不同，压力控制阀、流量控制阀和方向控制阀是液压阀的组成部分；溢流阀(安全阀)、减压阀、顺序阀、调整阀、分流集流阀等是流量控制阀的组成部分；控制方式的不同，开关式控制阀、定值控制阀和比例控制阀是液压阀的组成部分；液压系统的能量来源来自液压油，各种矿物油、乳化液和合成型液压油等均属于液压系统中传递能量的工作介质
本次设计的DG型液压缸是综合运用所学的基本理论、基本知识和相关的液压系统专业知识，完成对DG型液压缸的设计，并绘制必要的液压缸装配图、液压系统原理图。
本文通过设计DG型液压缸，分析液压缸的工作原理和动作过程，确定液压系统工作原理图，根据系统参数要求设计液压缸，完成液压缸的装配图，并且能够使大家对液压缸的具体结构构造和工作与原理有很好的认识和了解。

Abstract
DGtypehydraulicIn national economic construction, cement is the indispensable basis of raw materials. As an important basic industry, cement industry development has become a national and social development level and comprehensive strength is important measure index. The economy of our country is in the period of rapid development, infrastructure construction has become the main mode of domestic investment. Therefore, the cement as the main raw materialalso in the expansion phase.In the process of cement production, most of the raw material to be crushed, such as limestone, clay, iron ore, coal and other. Limestone is the productionof cement dosage is the biggest raw material, after mining of large size, high hardness, therefore limestone crusher in cement plant material crushing occupies a fairly important position. Crushing process than grinding process is economical and convenient, reasonable selection of crushing equipment is very important, the material into the grinding, as far as possible the large crushing to uniform, fine granularity, so as to reduce the grinding equipment load, improve mill output, but also conducive to the material uniformity, high accuracy of batching. Categories include: crusher jaw crusher, impact crusher, impact crusher, cone crusher, hammer crusher, gyratory crusher, compound crusher etc.. Strike back type crushing machine is composed of a rotor, cover, a base, a rear rack four parts, the upper cover is broken machine shell, and is associated with the internal structure of complement component, the inside of the upper cover of the lining board for stone crushing granularity and the crusher work efficiency plays an important role in. Cover design not only to request the appearance and practicability, a machine design too fancy will cause complex processing technology, manufacturing cost rises, bloated, will cause the transportation difficulty also increases the cost of manufacture. I am in the design process, focusing on the functional, material saving, light body, generous appearance aspects, especially in making the selection of materials, materials selected to both economy and durability.hnology at the same time, foreign enterprises and brand spread to more and more Chinese has become an opportunity. Cap pressing machine in industry through a variety of ways have been working with the relevant technology, and constantly improve their own strength and core competitiveness, and narrow the gap with developed countries.
In the new market demand, update the sleeve pressing machine is a pressing matter of the moment. The production of pipe pressing machine equipment manufacturing enterprises to fully tap the potential of the market, vigorously develop the sleeves of large low cost pressing special machinery and equipment, plays a positive role in the evolution of automatic assembly, the assembly of mechanical equipment.
