This paper proposes the solution to reduce the energy consumption of forming machine for the composite stringer manufacturing by applying the lean manufacturing techniques. The lean techniques such as standard operating procedures, single minute exchange of dies, external set-up based on production efficiency improvement are used to optimize the stringer manufacturing process. The improved set-up is performed during machine operation to reduce cycle time thus, enable continuous production of various stringers. As a result, the cycle time of development machine having the process improvement effects is reduced by 84.8%. In order to achieve this, the development machine is consisted of two lower stations, upper chamber, auto side indexes and quick centering devices. The work process is simplified by applying automatic machine instead of conventional machine. As well as the improved method produced two composite stringer in one cycle, it could reduce the machine energy consumption and increase the productivity.

高效节能的复合纵梁成型机

本文提出了一种通过应用精益制造技术来降低复合材料纵梁制造成型机能耗的解决方案。精益技术(例如标准操作程序,模具的每分钟更换,基于生产效率提高的外部设置)用于优化纵梁制造工艺。在机器运行期间进行了改进的设置,以减少周期时间,从而可以连续生产各种纵梁。结果,具有工艺改进效果的显影机的循环时间减少了84.8%。为了实现这一目标,显影机由两个下部工位,上部腔室,自动侧标和快速对中装置组成。使用自动机器代替传统机器可以简化工作过程。改进后的方法可以在一个周期内生产出两个复合纵梁,可以减少机器能耗,提高生产率。
