文档介绍：摘要
针对大连机车厂现有的工艺,本文利用工业工程相关理论对整个车轮工艺程序、流程以及布置径路进行了分析,并提出了相应的改进措施,为将来大连机车厂将要建设新的厂区提供设计参考。
(1)运用程序分析的方法,对大连机车厂车轮加工进行了工艺程序分析,绘出了改进前后工艺程序,对比说明了改进后提高了加工效率。
(2)运用流程程序分析以及布置和经路分析理论,从工艺流程以及布置和经路等方面对大连机车厂机五车间进行了改进,缩短了搬运时间,提高了效率。
(3)通过改进钻床的定位系统取消了划线定位打冲眼的加工步骤,节省了一道工序。通过改进检验设备来将磁粉探伤和超声波探伤工序合并达到优化的目的。将辐板孔倒角加工设备移动到钻辐板孔设备附近来减少搬运距离。将精车一加工设备移动到大门附近,把精车二加工设备移动到磁粉探伤仪对面,这样既减少了搬运距离又解决了路线交叉问题。通过改变半成品暂存位置来进一步减少搬运距离。

ABSTRACT
For the existing technology of Dalian otive Plant, we used the theory of industrial engineering technology program to analyze the entire wheel, process and path layout, and proposed measures for improvement accrondingly which would provide design reference to Dalian otive Works for the future to build the new plant
(1)We used program analysis methods to Dalian otive Works Wheel processing to the technology program analysis, plotted improvement program before and after the process, illustrated that we improved the processing efficiency after the improvement.
(2) We used the way of layout and flow of program analysis and theory of the way, from process and layout and the way, improved jiwu of Dalian otive Works, reduced the handling time and improved efficiency.
(3)By improved the crossed red eyes by improving the system positioning to save a process improved the equipment to unite the ic and ultrasonic testing to optimize the purpose of merging processes. moved the web hole chamfering processing equipment to the web hole drilled the equipment round to reduce the transition distance. Equipment of finish machiningⅠ would be moved to the main door, while Equipment of finish machiningⅡ would be moved to the opposite to the ic detector, which not only reduced the transition distance, but also solved the problem of the cross-cutting issues. Changed the temporary location of semi-finished products to further reduce the transition distance. And with the all of improvement we reduced the number of processing and saved the processing time
