模具正常寿命
模具正常失效前,生产出的合格产品的数目,叫模具正常寿命,简称模具寿命,模具首次修复前生产出的合格产品的数目,叫首次寿命;模具一次修复后到下一次修复前所生产出的合格产品的数目,叫修模寿命。模具寿命是首次寿命与各次修复寿命的总和。
Before the normal failure of the die, the number of qualified products produced is called the normal life of the die, referred to as the life of the die, the number of qualified products produced before the first repair is called the first life, and the number of qualified products produced after the first repair to the next repair is called the repair life. Die life is the sum of first life and repair life.
模具寿命与模具类形和结构有关,它是一定时期内模具材料性能、模具设计与制造水平。模具热处理水平以及使用及维护水平的综合反映。模具寿命的高低在一定程度上反映一个地区、一个国家的冶金工业、机械制造工业水平。
The die life is related to the type and structure of the die. It is the performance of the die material, the design and manufacture level of the die in a certain period of time. Comprehensive reflection of heat treatment level of die and mould as well as its use and maintenance level. To some extent, the service life of die reflects the metallurgical industry and mechanical manufacturing industry level of a region or a country.
