在批量生产中,模具寿命问题占有相当重要的地位,是当前模具设计、制造技术中的关键之一,也是国内外模具行业共同关切的大课题。影响模具寿命的因素很多,它涉及到模具设计、钢材质量、加工工艺、热处理及使用等方面。但是根据国内外一些单位对失效模具的典型调查分析看,造成模具过早失效的主要原因是:热处理不当.约占50%左右,有的甚至高达70%;其次是设计和加工工艺;原材料质量不好也占相当的比例。多年来国内外学
In mass production, mold life issues occupy a very important position, is the current mold design, manufacturing technology is one of the key domestic and international die industry is also a common concern of the big issues. Affect the life of the mold a lot of factors, it involves the mold design, steel quality, processing technology, heat treatment and use and so on. However, some domestic and foreign units of the failure of the typical investigation and analysis of mold, mold premature failure caused by the main reason is: improper heat treatment, accounting for about 50%, and some even up to 70%; followed by the design and processing technology; raw material quality Bad also accounts for a considerable proportion.
