重卷卷边机液压系统设计 摘要 在带钢冷轧上，不仅影响带钢的质量和产量，还会设备，给机组的稳定运行带来严重影响因此对进行研究和具有很重要的现实意义和经济意义。参照鞍钢冷轧2#生产线的实际情况，本文对液压系统进行设计。系统由阀液压缸运动，从而运行。本文分析了阀控缸各环节的工作情况，以及一些重要参数对系统稳定性和精度的影响，列出相应，。通过分析，系统能够同时满足稳定性、快速性和准确性的要求。本文液压系统进行了设计，确定了液压系统原理图，对液压动力元件、阀件和辅件进行计算和选用，对阀台等液压元件进行设计，并通过计算液压系统的压力损失、散热能力来对液压系统进行验算。结果证明，所设计的液压系统满足了设计要求。 关键词：冷轧；液压系统 The esign of Hydraulic System of Re-roll machine Abstract In the production line of the cold rolling, re-rolling not only seriously affects the quality and yield of the strip, but also seriously damages equipments, even have a serious impact on the stable operation of generating units, so study and control the system have a very important practical and economic significance.According to the actual situation of No.2 cold-rolled production line of Anshan Steel Company, this paper designed the hydraulic control system of rerolling. In the system，we use servo valve to make the cylinder move. Contents includes analyzing every part’s work and stress status in cylinder controlled by value units as well as influences that some key parameters made to system stability and precision. Through the analysis, we found the control system can simultaneously meets the requirements of stability, speed and accuracy. This paper has also carried on the design of hydraulic system, established the hydraulic system schematic diagram, calculated and selected the hydraulic power parts, the valves and auxiliary parts, designed hydraulic elements such as valve block, checked the hydraulic system by calculating its loss of hydraulic pressure and the cooling capacity. Checking results show that the design of the hydraulic system meet the design requirements. keywords：Cold rolling；Re-roll machine；Hydraulic system 目 录摘 要 I Abstract II 目 录 III 1绪论 1 1.1 国内外冷轧生产简介 1 1.2 重卷卷边机的作用和工作目的 2 1.3 冷轧重卷卷边机结构简介 2 1.3.1结构简介： 2 1.3.2 卷边机的工作过程 3 1.3.3运行件的动作范围 4 1.4 本次设计研究的内容 5 2 重卷卷边机液压系统设计 6 2.1 毕业设计主要参数要求 6 2.1.1 控制对象的有关参数 6 2.1.2 其他要求 6 2.2 重卷机液压系统的构成 6 3 液压系统的设计 8 3.1液压系统的组成及工作原理 8 3.1.1 拟定系统方案
