摘　　要：通过多个模具料屑维护的实际案列积累经验,总结出料屑产生原因及解决方法。从板料到冲压件的工艺过程进行细致分析。对落料、压机设备、模具3方面阐述,其中模具方面重点从拉延成型料屑,修边冲孔料屑及翻边整型料屑进行分析。并通过案列反射到新项目模具验收时关于料屑的注意事项,形成一套料屑维修标准流程,出现料屑问题时能直接进行借鉴。This paper summed up the causes of chip and solutions through many practical cases of mold chip maintenance experience.The paper analyzed in detail the process from sheet metal to stamping parts,described the blanking,press equipment and die,in particular it analyzed the die from drawing chip,trimming and punching chip and flanging chip.Such analysis was reflected to matters for attention regarding material chip in the new project mold acceptance,and a set of chip maintenance standard process was formed,which can be directly used for reference when the chip appears.
