在汽车冲压件开发过程中,外板如翼子板、门外板、机盖外板及后背门外板等是出现面品问题最多的外板制件。由于面品问题造成的返工率最高,是当前冲压件生产的瓶颈,需要在车型量产前将冲压件外板面品问题尽量全部解决,保证后序不再进行返工处理。文章主要针对后背门外板冲压生产过程中,车标的左右两侧不平的面品问题进行分析,找出原因,制定相应措施,利用8D分析法解决问题。
In the development of automotive stamping parts, the outer panels such as fenders, outer door panels, outer lid panels and back panel outer panels are the most problematic outer panel parts. Due to the highest rework rate caused by the question of surface products, it is the bottleneck of the current stamping parts production. Before the mass production of the vehicle models, the problem of the outer surface of the stamping parts should be solved as far as possible to ensure that the order is no longer reworked. In the paper, the paper mainly analyzes the problem of uneven surface of the left and right sides of the back door in the process of stamping production, finds out the reasons and formulates the corresponding measures, and uses 8D analysis method to solve the problem.
