摘要
分析了喷油器部件中关键零件衔铁的矫顽力技术要求和控制的意义,对矫顽力产生的机制和原理进行了剖析,提出了矫顽力控制的技术路径,结合生产技术实际条件,制定了正交试验(DOE)方案,试验数据表明:机械加工过程中,残余加工应力越低矫顽力越低,机械加工后,通过退火处理,可以有效大幅度降低矫顽力。
The specification of coercive force and its significance in control is described in this paper,and the mechanism in which armature plays a critical role in fuel injector assembly is analyzed.Based on mechanism analysis of the coercive force,the technical solution for its control is presented.Taking the actual production situation into consideration,a DOE for its improvement is designed.DOE trial data indicates that the lower of the residual stress during machining,the lower of the coercive force.Furthermore,annealing process can decrease coercive force significantly.
