摘 要
如今，液壓傳動是一門比較成熟的技術，已廣泛應用于機械制造、工程機械、農業(yè)機械、汽車制造以及鍛壓等機械行業(yè)。而其在實現(xiàn)高壓、高速、大功率、高效率、低噪聲、經久耐用，高度集成化等各項要求方面的顯著優(yōu)勢使得這門技術有著更加廣闊的發(fā)展前景。
本文在對液壓傳動發(fā)展和液壓傳動的工作原理作了一個簡要說明的同時，更對液壓技術在鍛壓機械中的一個典型應用——單柱液壓機的液壓系統(tǒng)進行了全面的設計計算。其內容主要包括：
Ⅰ 液壓傳動系統(tǒng)方案的分析、比較和確定；
Ⅱ 確定并繪制系統(tǒng)原理圖；
Ⅲ 集成塊單元回路圖的繪制；
Ⅳ 液壓系統(tǒng)中各主要參數(shù)的計算、圓整及校核；
Ⅴ 各種液壓元件的選擇；
Ⅵ 設計并繪制以集成塊聯(lián)接方式而成的系統(tǒng)裝配圖；
在單柱液壓機液壓系統(tǒng)執(zhí)行元件液壓缸的設計中，利用在前文系統(tǒng)設計中所校核過的如活塞直徑D（ΦAL）、活塞桿直徑d(ΦMM)等參數(shù)，我們對液壓油缸的各主要零部件進行了詳細的結構設計，并繪制了它們的零件圖及液壓油缸裝配圖。
在本設計中，所有圖紙均使用繪圖軟件CAXA（電子圖板V2版）繪制而成，使得圖紙更加清晰，一目了然。

ABSTRACT
Nowadays, hydraulic drive is a technique becoming mature, what has been applied in Manufacture, Engineering Machinery, Farm Machinery, Car Manufacturing, and Forging Presses etc. Moreover, it has a so salient advantage in actualize high pressure, high speed, hight-power, hight efficiency, low yawp, longevity and hight integration that it could develope much faster then others.
After the phylogeny of the hydraulic drive and the working theory have been introduced in this paper, we have do a fully design for the system of the single column hydraulic presses which is a type application in Forging Presses.It includes:
Ⅰ Analysing, comparing and confirming the project of hydraulic drive;
Ⅱ Confirming and drawing the system blueprint;
Ⅲ Drawing a blueprint of the cell loop of the integration block;
Ⅳ Accounting, checking and normalizing the mainly parameter in the hydraulic system
Ⅴ Choosing the different kinds of hydraulic component
Ⅵ Designing how to rig out all the parts of the system and then draw a blueprint to reflect it.
In the design of the working part of the hydraulic system, cylinder, we have do a particular frame design in using the parameter as the diameter of the piston D(ΦAL) and the diameter of the pole d(ΦMM).
In this project, to make blueprint more clearly and even be clear at a glance, we draw the entire blueprint in software CAXA.
