1、 I 摘摘 要要 板料折弯机在制造业及很多行业是必不可少的应用工具，液压板料折弯机充分利用液 压传动的优点、较高的劳动生产效率和使用特点得到广泛的应用。液压板料折弯机操作简 单。因而，操作人员并不需要很多的专业知识，经简单培训即可操作。 此次设计的目的是通过对液压系统的设计，让我们对液压传动有更清楚的认识，对液 压系统的组成和液压系统的元件的作用有深入的了解。液压系统中很多元件都是标准件， 在本设计中没有对标准件的设计，而只是对非标准件的设计，例如油箱、油缸的设计。 液压传动课程设计的目的有以下几点： 1、掌握液压传动课程及其它有关课程的理论知识并结合生产实际，进行液压传动设 计，液压传动课程
2、是理论知识和生产实践结合起来的一门功课。 2、在实践中学习和运用液压元件，尤其是各类标准元件的选择和运用，培养自主设 计能力，提高学生实际动手和运用的能力，为以后的工作打下基础。 3、通过毕业设计，提高学生在计算、绘图、查阅资料等方面的能力。 关键词关键词： 板料折弯机 ，液压传动系统，液压传动设计。 II Abstract Sheet metal bending machine is light industry and other industries indispensable application tools, hydraulic sheet metal bending machin
3、e but also for its high productivity and high cost performance by the users of all ages, and therefore is widely used. Hydraulic sheet metal bending machine is made full use of the advantages of hydraulic transmission, using electrohydraulic combined with the advantages of easy to realize automatic
4、control, makes the hydraulic sheet metal bending machine operation is simple. Therefore, the operator does not need a lot of professional knowledge, through simple training. Through the design of the hydraulic system is the purpose of this design can make to hydraulic transmission have more clear un
