卷圆机结构设计【毕业论文+CAD图纸全套】.doc

摘 要 本设计是关于卷圆机的结构设计。卷圆机是将各种型材卷制成圆环的一种高质量、高效益的卷圆装置。主要对卷圆机的传动系统、上下辊轮、压下装置以及卷圆机的总体进行设计和计算。 卷圆机结构型式为三辊对称式，在该结构中上辊下压提供压力，两下辊做旋转运动，为卷制板材提供扭矩。该机具有结构紧凑、操作简便、寿命长、噪声小、一机多用、质优价廉等优点，是工厂实现机械化生产的配套设备，该设备的上市可以大大减轻工人的劳动强度，提高企业生产效益。 关键词：卷圆机；辊轮；传动系统；压下装置；卷制 ABSTRACT This design is about flange machine. Roll round machine is made of various profiles will roll ring flange and a high quality, high benefit rolls round device ,mainly to transmission system, roll on the circle next roller, pressing device and roll machine design and calculation of the overall. Roll machine athreeroller symmetrical structure, in the upper roller press structure provides pressure, the two lower rollers make rotation, top provide torque. This machine with compact structure, easy operation, low noise, long service life, high quality and reasonable price multi-usage, etc, and is realized mechanization production factory, this equipment facilities listed can greatly reduce the labor intensity, improve production efficiency. Key words: Roll round machine ；Roll wheel ；Transmission system；Pressing device； Rolling 目 录 摘要-------------------------------------------------------------------------------------------------Ⅰ Abstract--------------------------------------------------------------------------------------------Ⅱ第1章 绪论---------------------------------------------------------------------------------------1 1.1 国内外发展现状--------------------------------------------------------------------------1 1.1.1国外发展现状---------------------------------------------------------------------1 1.1.2 国内发展现状--------------------------------------------------------------------1 1.2 卷圆机的类型和特点--------------------------------------------------------------------2 1.3本文设计内容------------------------------------------------------------------------------2 第2章 卷圆机工作方案的选择-----------------------------------------------------------3 2.1 卷
