后门内板褶皱问题的解决方法

The Solution to the Problem of the Inner Plate Folding

冲压生产过程中,内板类制件出现起皱不平问题,产生原因比较复杂,需要有系统的分析方法及对策。针对后门内板起皱不平问题,通过鱼骨刺图的分析方法,从模具结构、设备参数、材料性能、制件结构及工艺设计等方面进行分析阐述,确定问题真因,并提出解决该问题的有效方案,取得了满意效果。

During the pressing process, we have some problems like wrinkle and uneven on the inner panel and the reason of these problems are complex that we need systematic analysis methods and countermeasures. In this article, based on these inner panel wrinkle and uneven problems, we make use of cause and effect method to analyse and expound the die structure, equipment parameter, material performance, product structure and technology design, etc. And we have achieved some satisfied result in the area of find out root cause of the problems and put forward the effective countermeasures.
