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。

For the existing technology of Dalian Locomotive 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 Locomotive Works for the future to build the new plant

(1)We used program analysis methods to Dalian Locomotive 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 Locomotive 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 magnetic 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 magnetic 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.

Handling times did not change, but the removal efficiency improved significantly.
