1580热轧运输链试样采集装置液压系统 摘要 1580热轧生产线是当今先进的热轧生产线，代表着目前我过热轧生产的水平。其产品规格薄、性能好、表面光洁，适合国民经济和人民生活需要，得到广泛应用。因此其质量检测环节尤为重要。 1580运输链试样采集液压系统是运输链上的一个重要环节。本系统主要由压辊升降和试样小车移动两条回路。本设计针对现场生产情况的需要，结合液压传动技术、理论力学等知识的综合应用，通过液压系统方按的拟定、外负载的分析计算、执行元件的选择、液压控制阀的选择、系统性能验算和能源及辅助元件的选择等过程，对系统中两条回路分别进行了合理的设计，对各元件的选择进行了详细的说明，使其完全满足现场工作需要。 关键词： Samples collection devices of the transport chain hydraulic system in 1580 hot-rolled Abstract 1580 hot-rolling production line is advanced hot-rolling production line in todays, represents the level of hot-rolled production. Thin specifications of their products, performance, and smooth surface suitable for the needs of the national economy and peoples living standard has been widely used. Therefore particularly important aspect of quality.  Samples collection devices of the transport chain hydraulic system in 1580 hot-rolled is an important part. The system is mainly by the pressure roller and take-off and landing vehicle mobile two-loop sample. The design for the needs of field production, combined with hydraulic transmission technology, theoretical mechanics, such as the comprehensive application of knowledge, through the hydraulic system in accordance with the formulation side, the analysis of external load, the implementation of the choice of components, hydraulic control valve of choice, check system performance and energy and supporting the process of selection of components for the two-loop system were reasonable design, the choice of the components for a detailed description of the work to fully meet the needs of the scene Key words: hydraulic system, pressure roller system, the sample 目录 摘要 I Abstract II 一绪论 1 1．1引言 1 1．2 1580热轧运输链试样采集系统 1 1．3 1580热轧运输链试样采集系统的发展方向 2 1．4 运输链采用液压系统的优点 2 1．5 本设计的目的 3 1．6 本设计的重点问题和解决办法 3 二．1580热轧运输链试样采集装置液压系统的参数和构成 2．1毕业设计主要参数与 2．1．12．1．22．2 液压系统主要构成 三 液压系统的设计 3．1 液压系统的组成及工作原理 3．1．1拟定系统方案3．1．2液压系统工作原理3．2 确定液压执行元件的 3．2．1初选系统压力Ps3．2．2负载分析3．2．3运动分析3．2．4液压缸有关参数的确定3．2．5压辊缸参数的确定3．
