液压剪切机液压系统设计毕设论文.doc

PAGE 摘　要针对传统剪切机存在的噪音大、占地面积大、灵活性差等问题，本设计采用了液压驱动方式，解决了上述方面的缺陷。其设计内容剪切机的总体设计计算，主要零部件的设计计算和液压系统的设计，其中液压系统的设计还包括液压元件的设计。本文利用液压传动控制技术对剪切机进行改进设计，具有噪声小、剪切平稳等优点，是一种新形式的液压剪切机，能够更好地服务于剪切行业的发展，更好地适应国内外市场的需求，因此具有良好的市场前景。关键词：剪切机，液压系统，液压元件AbstractAbstractAim at the existing traditonal shearing machine that has high noise, large areas and poor flexibility etc problems, the design uses a hydraulic-driven approach to address these deficiencies. It mainly includes three partial contents: the overall design calculation of the shear machine, the design calculation of the main components and hydraulic system design. The hydraulic system design has mainly included the design of the hydraulic components. This paper makes some reconstuction design for shearing machine with hydraulic transmission and control technology, and the improved shearing machine has advantages of low noise, smooth cutting and is a new typle hydraulic shears, which can serve the shearing industry and meet the needs of domestic and foreign markets better. Therefore the hydraulic shearing machine has a good market prospect.Key words: Shearing machine, Hydraulic system, Hydraulic components目 录目　录 TOC \o 1-3 \h \z \u HYPERLINK \l _Toc264054099 摘要 PAGEREF _Toc264054099 \h I HYPERLINK \l _Toc264054100 Abstract PAGEREF _Toc264054100 \h II HYPERLINK \l _Toc264054101 目 录 PAGEREF _Toc264054101 \h III HYPERLINK \l _Toc264054102 第一章　引言 PAGEREF _Toc264054102 \h 1 HYPERLINK \l _Toc264054103 1.1课题的背景和意义 PAGEREF _Toc264054103 \h 1 HYPERLINK \l _Toc264054104 1.2剪切机的发展及现状 PAGEREF _Toc264054104 \h 2 HYPERLINK \l _Toc264054105 1.2.1剪切机的分类 PAGEREF _Toc264054105 \h 2 HYPERLINK \l _Toc264054106 1.2.2国内研究现状 PAGEREF _Toc264054106 \h 4 HYPERLINK \l _Toc264054107 第二章　总体设计计算 PAGEREF _Toc264054107 \h 6 HYPERLINK \l _Toc264054108 2.1现有剪切机结构原理及存在问题 PAGEREF _Toc264054108 \h 6 HYPERLINK \l _Toc264054109 2.2设计要求 PAGEREF _Toc264054109 \h 9 HYPERLINK \l _Toc264054110 2.3液压剪切机的总体设计 PAGEREF _Toc264054110 \h 10 HYPERLINK \l _Toc264054111 2.4
