Study On The Process Layout Design Of SCR Post-processor Production Line

In 2014,the ministry of industry and information technology announced that the declaration,which is applicable to the national three diesel vehicles,will be completely annulled on December 31,2014,and the products will not be sold on January 1,2015.Although the current four countries have not yet fully implemented,there are already a number of places that have already begun implementing the four standards,so it is fair to say that the four standards continue to be carried out in an unblocked manner;After the construction of a country ? automobile exhaust processor production line is the automobile industry development milestone.In this paper,the construction of SCR box production line of shaanxi automobile company is the research object.The main work of this paper is:(1)Through the introduction of the working principle of SCR system,the working principle of the post-SCR box and the internal structure of the product are analyzed to understand its internal structure and increase its understanding of the product.Also understand the main technical conditions of the product.The main processing control points of this product are decomposed.The process design should be designed specifically.(2)By disassembling the overall structure of SCR box,the parts of the product are classified,and the parts that need to be processed are screened out.Analyze the product characteristics of self-made parts and divide the production line.(3)Through the analysis of the parts structure,the process of parts processing is determined,and the selection of process equipment is carried out according to the characteristics of each process.Through the analysis of the structure and characteristics of the activator and gasket,the characteristics of the products are mastered,the packaging of the catalysts and the structure of the equipment are formulated.By analyzing the structure of the box,the process of box processing is divided.According to the characteristics of the product,welding equipment,airtight inspection equipment and equipment selection.Meanwhile,the production efficiency of the equipment is(4)Calculate the number of equipment by computing the production of the production line;According to the equipment characteristics of each processing unit,the personnel of the production line shall be equipped;After the research of the product processing process,the processing flow of the product is determined and the process layout is preliminarily determined.Select raw materials and transport mode of products according to the initialprocess layout;The minimum packing and floor area of the raw material are determined by the production beat of the production line.According to the structure characteristics of the transmission order of the material and equipment for the design of equipment placement direction,combined with the raw material area and production safety distance,and other factors of production line equipment design home.After the demand for raw materials and the storage requirements of finished products,the area of demand is determined and the overall layout design of the workshop is carried out.
