Research on Product Design and Forming Technique of Fender to Meet Four-operation Forming Scheme

翼子板是车身覆盖件中成形难度最大的零件之一,其结构特点决定了成形工艺,而冲压工序数又直接影响产品的生产成本和成形精度。研究了各种翼子板的结构特点和冲压工艺,提出了基于冲压工艺正交试验的翼子板产品结构优化设计方法。此外,以某车翼子板开发为例,采用本优化方法对该翼子板零件进行优化,并研究了翼子板四序冲压成形工艺的关键技术。借助于本优化分析方法,可以在车型车身结构设计阶段,指导其翼子板产品满足四工序冲压的结构设计。
Fender is one of the auto-body panel which is the greatest difficult to form. The forming process of fender is determined by its structural characteristics, and the number of forming process directly affect its cost of production and its forming precision. Studying the structure characteristics of various fender and their stamping process, we propose the structure optimization design method of fender product based on the orthogonal design. With a car fender development as an example, the fender is optimized and the key technology for the four-operation stamping scheme of fender is researched. This optimization analysis method can guide fender product structure design to meet the four-operation forming scheme for the car body structure design
