About 2.5L Scheme Of Optimization, The Crankshaft Production Line And The Study Of Bottleneck Process Optimization

From the car sales growth rates of recent years our country’s automobile market potential is very huge, especially in the passenger car market is constantly expanding. And more and more is also high to the requirement of automobile parts, especially for 5c in engine parts, high precision, stable quality, low cost requirements, delivery requirements in a timely manner, this is suppliers are facing a very serious situation. T company is a production engine is one of the 5 c a crankshaft professional manufacturers, the company in the production of the crankshaft production line up to more than 40, key equipment are sourced from the United States, Germany, Britain and other developed countries, the equipment advanced degree in international is a leading position in the industry. But the company in the production of passenger cars in the crankshaft production line is less than 1/10 of the total production line, mainly the production of light trucks, heavy card the crankshaft. In recent years, the company in the rapidly growing passenger car crankshaft and sample through which soon after batch production, this needs the company of passenger car crankshaft production line planning, to meet changing market requirements.2.5 L engine series, on the basis of the introduction of Italian company VM technology is the development of small passenger cars with engines, V emissions that can fully meet the state requirements. After the engine crankshaft using alloy steel forging forging and the manufacturing cost is high, the processing technology is complex, single parts costs and prices. After the crankshaft batch no special line for production, through borrowing other production line for mass production, in the process of production can not achieve a flow production, due to backflow process more frequent leakage process, unable to effective control of quality. The original production line layout is unreasonable, each operator can only operate a device, use more staff. By using lean tools to build sheet flow as the goal, using the line balancing tools, determination of take time, the optimization of technological process, the determination of job enrichment degree of eliminating the bottleneck process, operating personnel, personnel of combination of unit production line configuration to achieve efficiency.
