【摘要】 随着经济全球化、信息化与知识化,汽车制造业所面临的市场环境正在急剧变化。这种环境使得制造业的产品周期缩短,产品更新加快,产品种增加,产品批量减少。生产线平衡的目的在于通过对制造资源的合理规划、控制和调度,提高制造资源的利用率、缩短制造周期,降低库存,从而实现多品种、小批量、高质量、低成本的柔性化生产。本文以近年来迅速发展的上汽通用五菱股份有限公司冲压生产线为研究对象,研究对象包括5条手动冲压生产线,1条自动化冲压生产线,5大车型系列共计80多种冲压件；通过对冲压生产线的生产方式进行深入的调研和分析,研究了冲压线多品种混线生产以实现生产线平衡的相关方法。研究从以下几个方面展开：首先分析了生产线平衡的国内外发展现状和趋势,指出本文的研究方向；其次剖析了现有冲压生产线生产模式,通过比较手动冲压线设备与自动化冲压线设备、手动线模具与自动线模具的之间的差异,指出实现冲压生产线平衡的解决方法；再次讨论了精益生产在生产线平衡中的应用。冲压由于工艺的特殊性,要实现各冲压生产线、各工序的生产平衡难度很大；为了解决上述问题,必须对各线、各工序的作业时间进行平均化,同时对作业进行标准化,以使生产线顺畅流动；然后根据上汽通用五菱股份有限公司冲压车间的生产实际需求,利用仿真技术对各冲压件在各线的生产组合方式进行了模拟,并根据模拟的实际情况进行分析,找出最佳的生产组合,达到均衡各线生产负荷,使车间生产的每一种冲压件都能够用最优的方式进行生产；最后对冲压的生产体系进行整合,开发了冲压排产软件,提升冲压排产准确性及排产效率,实现提升车间生产效率的目标。更多还原

【Abstract】 The market environment makes the automotive manufacturing to shorten the product cycle time, to increase product variety, to reduce product volume. The purpose of line balancing is to increase the resource utilization rate, to shorten manufacturing periods, to reduce stack in producing, which leads to better quality, lower cost and higher efficiency.This paper puts research on the press lines of SGMW. Conducting in-depth research and analysis of the press lines of multi-species mixing production to achieve balance related methods. Research from the following aspects:Firstly, analyzed the current development status and trends of production line balancing;Secondly, analyzed of the existing mode of stamping production line, by comparing the differences of manual and automatic press lines, a balanced solution is obtained;Thirdly, discussed the application of lean production in the production balancing. As the special process, to achieve the production line, production balance each process very difficult; to solve the above be of crucial importance Lines, the process time averagely, while on the job for standard, to the production line smooth flow;Fourthly, according to SGMW press shop actual production demand, use of simulation technology on the production line in each combination is simulated and the simulation to analyze the actual situation to find the best production combination, to achieve a balanced load each line of production, so that each workshop production of parts can be produced with the best way;Finally, integrated production system to develop a press scheduling software to improve punching accuracy and scheduling scheduling efficiency and improve plant efficiency.更多还原
