摘要
车身外覆盖件一次合格率(FTT)是冲压质量评价的一项重要指标,以铝发盖外板为例,从人机料法环5个维度对麻点和刮痕问题进行分析并制定对策,通过提升线体、设备和模具清洁度,优化模具表面状态和铝卷纵切刀具间隙,调整铝板轧制过程的张力控制模型,以降低铝发盖外板麻点和刮痕缺陷产生频次,铝发盖外板FTT从85%提升至92%以上。
The First Time Through(FTT)of body outer cover panel is an important index of stamping quality evaluation.Taking the outer plate of aluminum cover as an example,this paper analyzed the problem of pitting and scratches and formulated countermeasures from 5 dimensions of man-machine material method ring.By improving the cleanliness of wire body,equipment and die,the surface state of die and the gap of longitudinal cutting tool of aluminum rolling were optimized,the tension control model of aluminum plate rolling process was adjusted,which reduced the frequency of pitting and scratch defects of aluminum cover outer plate,improved the FTT of aluminum outer cover from 85%to more than 92%.
