Study On Time Optimization Of TR Company Coupe Crankshaft Production Line

The automobile industry after decades of development, has become one of the key industries dominated the national economy, the automobile industry can drive the synchronous development of peripheral related industries, including chemical, mechanical, electronic, chemical materials, and so on a number of related industries, the automotive industry has become a pillar industry and gradually strengthened. With the rapid development of national economy, social public consumption ability is steadily improving, people in the car on the market consumption is to improve synchronization. Because of the rapid development of automobile industry, the demand for auto parts is increasing year by year, to promote the rapid development of auto parts industry, but the quality level of the vehicle factory, but more and more demanding requirements. Requirements of large background constantly demanding on the quality of the products in the domestic parts production capacity and customer, enterprises are facing more and more strict manufacturing level, and therefore must be used with high precision production equipment, the use of lean manufacturing and six sigma theory, optimization of machining, reduce the production cycle, improve product quality and production efficiency, reduce production cost.In this paper, through the study of car crankshaft production line process, process and production line balance, optimization of crankshaft production process scheme, design a car crankshaft production line speed reasonable optimization scheme. Process mainly using the field observation and measurement time data, through the analysis program, analysis of operation, analysis, process analysis, action TT/CT chart analysis and find out the influence of the whole line rhythm problems, using tools, lean production methods, the use of "principle of motion economy" tools such as cycle time optimization of car crankshaft production line, make car crankshaft production line the beat is the greatest degree of optimization, improve the car crankshaft production line balancing rate, to provide satisfactory service for customers, to create more benefits for enterprises.
