摘   要

空调后盖折弯机是一种利用液体静压力来加工金属、塑料、橡胶、木材、粉末等制品的机械。它常用于压制工艺和压制成形工艺，如：锻压、冲压、冷挤、校直、弯曲、翻边、薄板拉深、粉末冶金、压装等等。
液压传动系统是空调后盖折弯机械的一个组成部分，液压传动系统的设计要同主机的总体设计同时进行。着手设计时，必须从实际情况出发，有机地结合各种传动形式，充分发挥液压传动的优点，力求设计出结构简单、工作可靠、成本低、效率高、操作简单、维修方便的液压传动系统。
本人系统学习了液压系统技术的知识，查阅了一些相关的文献资料，在此基础上，结合本人的设想和设计工作中需要解决的任务，主要进行了以下几项工作：
（1）拟定空调后盖折弯机液压原理图。
（2）完成空调后盖折弯机油缸的设计。
（3）完成空调后盖折弯机液压站的设计。
（4）对液压系统进行校核设计
（5）完成对空调后盖折弯机整体三维建模设计
关键词：空调后盖折弯机，油缸，液压系统
 

Abstract

Hydraulic machine (also known as: hydraulic machine hydraulic machine) is a static pressure using liquid to the processing of metal, plastic, rubber, wood, powder and other products. It is often used for pressing and pressing forming process, such as: forging, stamping, cold extrusion, straightening, bending, flanging, sheet metal drawing, powder metallurgy, pressing etc..
Hydraulic drive system is a part of hydraulic machinery, hydraulic transmission system design to the overall design of the same host at the same time. To design, we must proceed from the actual situation, the organic combination of various transmission forms, give full play to the advantages of hydraulic transmission, and strive to design hydraulic transmission system has the advantages of simple structure, reliable operation, low cost, high efficiency, simple operation, convenient repair.
I am learning system of hydraulic system of technical knowledge, access to some of the relevant literature, on this basis, combined with the need to address my ideas and design work, the main work is described as follows:
(1) the development of  hydraulic press hydraulic principle diagram.
(2) completed the design of  hydraulic cylinder.
(3) to complete the design of  hydraulic station.
(4) were checked for the design of hydraulic system
(5) the completion of the  hydraulic press overall three-dimensional modeling design
Keywords:  hydraulic machine, hydraulic cylinder, hydraulic system
