基于单件流的叶轮轮毂及柜体精益生产研究

Research on Lean Production of Impeller Hub and Cabinet Based on Single Piece Flow

针对JF公司2.5 MW风电机组的叶轮轮毂及柜体生产中存在物料交接慢,备料过程串行,装配、检验、收尾以及包装过程交叉驱动,生产过程节拍不统一,人员操作过程中存在瓶颈工序等问题,基于精益生产的思想,综合运用流程程序分析、价值流图析等工业工程相关方法和工具,通过重组班组作业、修改员工作业流程、细化员工工作任务、对产线员工进行人员培训等,使叶轮轮毂及柜体的作业步骤由原来的16个缩减到8个,作业周期由原来的13 h缩减到8.5 h,加班时间由原来的4 h缩减为不加班或只加班0.5 h,生产平衡率由48.24%提升至64.04%,解决了生产过程中价值流现状图存在的效率低下的问题。

Comprehensive use of lean production ideas, this paper studies and analyzes the single - piece flow production of the impeller hub and cabinet of JF 2.5 MW wind turbine through the process program analysis, value flow diagram analysis and other industrial engineering related methods and tools. Reasonable improvement schemes are put forward for the control of production rhythm, optimization of production process, standardized operation and staff training. The research results show that this method can improve the production efficiency of enterprises and shorten the production cycle.
