内容简介：

摘要国产压砖机的技术参数、技术性能等己达到或部分超过国外先进压砖机的水平，但液压系统的设计主要借助于经验，而理论上的研究工作较少。因此，对自动压砖机的液压系统理论基础仅进行研究，为改进、优化液压系统，提高压制次数，缩短循环时间，提升压砖机的产能提供理论支持有一定的积极意义。本文主要任务就是了解液压压砖机的整体结构，对液压机本体结构的主要部件进行强度核算，保证机器的运行安全。同时根据压力和流量这两个液压系统的主要参数来选择液压元件、辅件和原动机的规格。最后对液压机的技术性能进行估算，以便从几种设计方案中比较出最佳方案，或判断其设计质量。本文中进行了：系统压力损失计算，系统效率计算，系统发热与温升计算，液压冲击计算等。关键词：压砖机；本体结构；优化设计 AbstractThe design and manufacturing level of hydraulic automation tile press has taken remarkable achievement not only by introduction, duplication and digestion of oversea advanced equipment, but also by independent manufacturing of hydraulic automation tile press with knowledge authorization. Although the technological parameters and functions of domestic hydraulic automation tile press has been gained or exceeded partly oversea advanced technological level of hydraulic automation tile press, design on the hydraulic system is based on working experience with less theoretic research. Therefore, it is positive to do theoretic base research on hydraulic system to improve, optimize hydraulic system, shorten cycle time and increase production. Learn the whole construction of the hydraulic jewel press machine, and figure up the strength of the main components to ensure its safe running.Pressure and flow capacity are the main parameter of hydraulic system, according to which we can calculate and choose the specifications of elements, auxiliaries and the prime motor. And last,estimate the technical data of hydraulic press to cull a best one from the several designed plans, or to judge its quality. This paper contains: calculations of system pressure, system efficiency, system heat emitting and temperature raising, hydraulic shock and so on. key words: brick press noumenon configuration optimum design- III -目录1 绪论.11.1液压压砖机的现状与发展趋势.11.1.1国内液压压砖机的现状与发展趋势.11.1.2国外液压压砖机的现状与发展趋势.22 设计计算的内容和步骤.43 液压机本体结构及设计计算.53.1液压压砖机液压系统的组成及功能.53.2液压压砖机的液压回路.53.3本体结构的选择.53.4立柱的强度计算.63.5横粱的强度与刚度计算.74 确定液压系统的主要参数.114.1 初选系统压力.114.2 计算液压缸主要尺寸及其选择.114.3 计算液压马达排量.154.4 计算液压缸或液压马达流量.164.4.1液压缸的最大流量.164.4.2 液压马达的最大流量164.5 液压马达的选用.175 拟订液压系统图.185.1 确定和选择基本回路.185.2 调速方式的选择.185.3 油路循环形式的选择.195.4 需要综合考虑的其他问题.196 液压元件的选用.216.1 液压泵的选择.216.1.1 确定液压泵的工作压力.236.1.2 确定液压泵的流量.236.1.3 选择液压泵的规格.246.1.4 确定驱动液压泵的功率.246.2 控制阀的选择.266.2.1 压力控制阀的选择原则.266.2.2 流量控制阀的选择.266.2.3 方向控制阀的选择.266.3 蓄能器的选择.286.4 管道种类的选择.286.4.1 管道内径的确定.296.4.2管道壁厚的确定.306.4.3 管接头的选择.316.5确定油箱容量.316.6 过滤器的选用.326.7 液压油的选用.337 液压系统性能估算.357.1 系统压力损失计算.357.2 系统效率估算.367.3 液压冲击估算.378 压制油缸优化设计.398.1前言.398.2单层厚壁油缸的应力和应变分析.398.3薄壁油缸的应力
