摘要
对洗衣机脱水电机矽钢片冲模的早期断裂与崩刃,运用多种测试手段进行失效分析。结果表明,模具的失效主要是模具材料化学成分不合格、热加工工艺不适当以及凸凹模配合间隙不合理所致,在此基础上提出相应的改进措施。
In this paper,early stage fracture and cutting edge break of dies of washer whizzer motor Silicon steel flat are analysed by means of multiple measurement methods. The results show that failure reasons primarily are incorrect techenology of hot working,unqualified Chemical Composition of dies materials,improper match space of dies and careless mainfenance and so on. Some improvements have been proposed on the basis.
