内容简介：

徐州工程学院毕业设计（论文）摘要通过对分析液压压砖机的国内外生产及研究现状，确定了本课题的主要设计内容。在确定了压砖机初步设计方案后，采用了传统设计方法对1250T液压压砖机机身结构进行设计计算及强度校核，并采用AutoCAD设计软件对上横梁、底座、拉伸滑块、压边滑块、拉伸缸、压边缸、顶出缸、立柱及总装图进行了工程绘图，在参考了某公司生产的四梁四柱式液压墙体压砖机机液压系统以及查阅了有关关于液压系统设计的书籍后，确定了全自动数字控制系统的设计方案，绘制了数字控制系统的梯形图，设计了电气系统的工作说明书，并对其进行了可行性分析，最后对整个设计进行系统分析，得出整个设计切实可行。关键词 压砖机；机身结构；数字控制系统AbstractThrough to analysed the type hydraulic press domestic and foreign research present situation, I had determined this topic main design content. After I had determined the type hydraulic press preliminary design plan, used the traditional theory method to carry on the design, the computation, the intensity examination to the body of 1250T hydraulic presses fuselages structure, used AutoCAD design software to the main traverse, under the crossbeam, moves Liang, the master cylinder, goes against the cylinder, the column, the final assembly drawing had carried on the project cartography, meanwhile had carried on the mapping to the master cylinder; After referred to three Liang four columns hydraulic Type hydraulic press of wall hydraulic system which some company produces as well as has consulted massively and the hydraulic system design books, the definite system of numberal control design proposal, had drawn up the hydraulic system schematic diagram, had produced the system of numberal control working instructions, and had carried on the feasibility analysis to it, finally carried on the system analysis to the entire design, obtained the entire design to be practical and feasible.Keywords Hydraulic press body structure Numberal control system目 录1绪论.11.1压砖机的发展.11.2压砖机的概述.21.2.1压砖机应用领域.21.2.2压砖机的工作原理和主要参数.31.2.3国产压砖机的主要技术性能.52 YZ-1250压砖机机身结构设计.72.1用途和特点.72.2结构及工作原理.72.3 YZ-1250主体结构设计.92.3.1上横梁的设计、计算及效核.92.3.2下横梁的设计、计算及效核.132.4液压缸的设计、计算及效核.152.4.1负载分析.162.4.2主液压缸主要参数的确定.162.4.3顶出缸的设计.192.5立柱部分设计及计算.192.6柱塞与活塞.252.7机身的紧固.263 电气系统的控制.293.1电气系统的概述.293.2电气原理说明.293.3梯形图及编程.314调运、安装
