金属材料分选仪在锻件硬度检测上的应用

Metal Material Separation Application for Forging Rigidity Testing

为了检测焊接钢质药筒热处理后的物理性能,保证药筒射击后能顺利退壳,介绍了焊接钢质药筒筒底热处理后的硬度分选技术,指出了采用硬度计所存在的问题和金属材料分选仪在检测锻件表面硬度时的优势.通过现场试验,以硬度计检测复检确认了金属材料分选仪的可靠性,并进行靶场退壳试验.结果表明,采用金属材料分选仪进行硬度检测,能保证焊接钢质药筒的退壳性,并可实现大批量、高效率、自动化生产线锻件的在线检测.

This paper presents rigidity separating technique alter heat treatment of me bottom of welded steel dynamic tube and indicates the problem of using sclerometer and the advantage of metal material separation for forgings surface rigidity testing. Through field test, the reliability of metal materiai sepa- ration is affirmed by sclerometer testing repetition measurement. Moreover, ejection experiments are made in shooting range. The research in this paper surveys that ejection of welded steel dynamic tube can be ensured by using metal material separation to make rigidity test. And the forging online testing of automatic line is realized in mass productions and high efficiency.
