应用直读光谱分析仪、洛氏硬度计、金相显微镜、磁力探伤机等检测仪器,对一些冷作模具失效件进行检测分析,得到的失效原因各不相同:选择三件不同材料制造,多种不同原因造成的失效案例,根据不同原因采用相对应的整改措施后,避免了同类质量事故的重复发生,也使这类模具的使用寿命都在逐步提高,。 Application of direct reading spectrometer, Rockwell hardness tester, metallographic microscope, magnetic testing machine and other testing instruments, some of the cold die failure detection analysis, the failure causes are different: choose three different materials, and more Due to different causes of failure cases, according to different reasons after the adoption of the corresponding corrective measures, to avoid the recurrence of similar quality accidents, but also the life of such mold are gradually increased.
