毕业设计（论文）-钢坯拨装置设计（全套图纸）.doc

武汉科技大学本科毕业设计PAGE PAGE I 摘要 拨钢机是轧钢车间上料区主要设备之一，其作用是将加热炉前辊道上的钢坯或炉前上料台架上的钢坯推入加热炉进行二次加热过程。本设计选用了机械式拨钢机，在拨钢机结构设计上主要采用了齿轮齿条的结构形式。该机构具有结构简单，整体尺寸适中，传动效率高，维修方便，造价较低的优点。在本设计中主要对推钢机进行了结构设计和理论计算，并着重对传动机构做了详细的分析设计。关键词：拨钢机；结构设计；理论计算全套图纸加153893706Abstract Pushing steel-rolling workshop is based on one of the main equipments─ Dialing steel-machine, and its role is to push the billet material which lies on the Roller or the bench before the furnace into the furnace for reheating process. The design chooses a mechanical Dialing steel-machine,while the structure designed primarily for the use of the gear and rack structure. The advantages of the structure exists that the body is simple in structure, the overall size of moderate, high transmission efficiency, easy maintenance, the lower cost.The main content of the Dialing-design includes the structure design and theoretical calculations and focus on the transmission mechanism to do a detailed analysis and design.Keywords: Dialing steel-machine; Structural Design; Theoretical calculations目录 TOC \o 1-3 \h \z \u HYPERLINK \l _Toc295473547 前言 PAGEREF _Toc295473547 \h 1 HYPERLINK \l _Toc295473548 第一章 概述 PAGEREF _Toc295473548 \h 2 HYPERLINK \l _Toc295473549 1.1轧制工艺过程简介 PAGEREF _Toc295473549 \h 2 HYPERLINK \l _Toc295473550 1.1.1轧制工艺过程 PAGEREF _Toc295473550 \h 2 HYPERLINK \l _Toc295473551 1.1.2轧制工艺过程的设计与实施 PAGEREF _Toc295473551 \h 3 HYPERLINK \l _Toc295473552 1.2拨钢机的简介 PAGEREF _Toc295473552 \h 3 HYPERLINK \l _Toc295473553 1.2.1拨钢机的种类 PAGEREF _Toc295473553 \h 3 HYPERLINK \l _Toc295473554 1.2.2链式拨钢机的结构 PAGEREF _Toc295473554 \h 3 HYPERLINK \l _Toc295473555 1.2.3设计中应注意的几点事项 PAGEREF _Toc295473555 \h 4 HYPERLINK \l _Toc295473556 第二章 传动方案的分析与拟定 PAGEREF _Toc295473556 \h 5 HYPERLINK \l _Toc295473557 2.1传动方案的分析 PAGEREF _Toc295473557 \h 5 HYPERLINK \l _Toc295473558 2.1.1常用的传动类型及其特点 PAGEREF _Toc295473558 \h 5 HYPERLINK \l _Toc295473559 2.1.2机械传动系统设计时应注意的事项 PAGEREF _Toc295473559 \h 5 HYPERLINK \l _Toc295473560 2
