摘要
    在经济全球化背景下，现代机械产品向着高精度、高自动化和高可靠性发展、具有机电结合和多学科技术结合的特点，纯机械的产品越来越少，而且更新换代速度越来越快。机械工业是一个国家的重要产业，机械工业的发展无时不刻都在影响着国家经济的发展，人类的进步离不开机械工业的发展。在全球经济发展的大环境下，中国各个行业被其他国家的先进技术影响的同时，越来越多的外国企业和品牌传播到中国已经成为现实。在新的市场需求的推动下，对棒料切割机进行改良和优化是当务之急。生产棒料切割机的企业，必须充分考虑到在棒料切割机运行中可能出现的问题，尽量使棒料切割机的自动化程度越高越好，从而减少人工搬运工具的时间，国内棒料切割机的研发及制造要与全球号召的高效经济、安全稳定主题保持一致。棒料切割机的发展与人类社会的进步和科学技术的水平密切相关。    
    本次设计在题目是棒料切割机在设计，目前，国内棒料切割机的研发也在向朝着运行高速化、功能复合化、控制智能化的方向发展，廉价，简单，方便成了工作台发展的主题。

Abstract
This graduation design is the optimization design of driving roller conveyor, first on the driving roller type conveyer is summarized; then analyzed the selection principle and calculating method of driving roller conveyor; then calculated based on these design criteria and abase is designed; then checked on the main parts selected conveyor. Is the drive roller conveyor consists of four main parts: driving device, tension device, middle rack, and the moving part. Finally, a simple description of the installation and maintenance of transport. At present, the drive roller conveyor is moving towards long distance, high speed, low friction direction, air cushion conveyor in recent years is one of the.
In the design, driving roller type conveyer manufacture and application, at present our country compared with foreign advanced level there are still large gaps, domestic in the design and manufacture of driving .This design is the optimization design of driving roller conveyor.
