Balance Optimization Of The Side Wall Line Of C70E Open-top Wagon Of BC Company

With the rapid development of China’s economy,the level of railway freight transportation has increased year by year,and railway transportation has become a new growth point of China’s economy.All railway wagon manufacturers are facing increasingly stringent requirements from users and pressure from competitors.In order to ensure market share,we have to improve production and operation level and enhance market competitiveness through various means of improving quality and efficiency.As a typical railway wagon production company,the BC Company has continuously upgraded its technology,especially invested a lot of advanced equipment in the side wall production line.It has the highest level of automation and intelligence and can basically achieve "one-stream" production.However,in recent years,the production capacity of its side wall production line has begun to appear bottlenecks,often resulting in difficulties in delivering products on schedule,seriously affecting the overall production capacity increase,and even jeopardizing the credit evaluation of the company.To achieve the purpose of reducing costs and increasing efficiency.In order to carry out the research on the optimization of the balance of the production line of the side wall of the C70 E open-top wagon of BC Company,this paper first collects the relevant theories of the balance of the domestic and foreign production lines and the evaluation index system of balance.Evaluation index system to determine the research content and methods of this article,and formulate a technical route to optimize the balance of the BC company C70 E open-top wagon side wall production line,and then by measuring the standard operating time of all processes on the production line,combined with the required to complete the current order Production cycle,identify the super cycle process that restricts the improvement of efficiency,and calculate and evaluate the balance rate and smoothness of the production line according to the index system determined above Using the "5W1H" six-he analysis method,the ECRS process optimization and the principle of labor saving and other theoretical tools,from the aspects of process optimization,process adjustment and actionimprovement,the bottlenecks and the processes and operations that restrict production balance are improved,and targeted And implement the improvement plan.By applying the research results of this article,the production cycle of the BC company C70 E open-top wagon side wall production line has been satisfied,the original super cycle process is eliminated,the operating time is less than the production cycle,and it fully meets the predetermined production cycle demand.Secondly,the balance of the production line is improved.The balance rate is increased from 58.54% to 68.83%.The smoothness index is reduced from 22.37 to 18.55.The work load and work time between the processes tend to be balanced,the dispersion of work time is reduced,and the personnel The idle situation is controlled,and the process can be produced according to one flow.Once again,the production cost was reduced.After a series of optimizations such as process cancellation,merger,and rearrangement,the number of C70 E open-top wagon side wall production processes was reduced from 12 to 11 and the number of operators was reduced from 30 to 29.The BC company’s production and operating costs are reduced.Finally,the equipment utilization rate is improved,the equipment failure rate is reduced,the equipment service life is prolonged,the operation time of the entire production line is shortened by reducing unexpected downtime,and the production efficiency is improved.
