以精益化生产理念优化回转体加工工艺的实践

Practice of Optimizing Rotary Body Processing Technology by Using Lean Production Concept

介绍回转体零件的工艺优化及模具创新设计过程,指出了原压铸工艺存在的问题。通过精益化生产工艺改进,实现了回转体一次直接压铸成形工艺,减少了一些机加工工序,弥补了目前模具抽芯机构的空白,提高了零件的生产效率.降低了生产成本,使综合良品率由88.2%提高.到94.0%,千件工时由155.2 h降到73.0 h,经济效益显著提高。

This paper introduces process optimization of rotary body and process of mold innovation design, and point out the problems existing in original diecasting process. Through improvement of lean production technology, rotary body is directly diecasted, some machining procedures are reduced, blank of mold without corepulling mechanism is made up, production efficiency of parts is improved, production cost is reduced, and yield rate is increased from 88.2% to 94.0%.The working hours per thousand pieces decreased from 155.2 h to 73.0 h, and the economic benefits were significant.
