| 为了减少汽车翼子板冲压模具工序数量，降低汽车翼子板制造成本，以某SUV车型翼子板为研究对象，在分析产品冲压工艺的基础上，提出了一种采用工序集成技术的三工序冲压方案。通过将侧冲孔与侧翻边整形复合，并对大角度、长法兰翻边采用一次侧整形工艺，实现了翼子板侧冲孔、侧翻边、侧整形等不同工艺内容的同序化。介绍了满足翼子板三工序要求的翻边整形模结构，阐述了三种不同类型的特殊斜楔机构的结构布局和工作原理。最终完成了三工序化翼子板的工业化应用，达到了批量生产的要求。研究结果表明，三工序冲压方案能够有效缩短翼子板冲压工序，大幅削减翼子板的生产成本。 |

| In order to reduce the number of automotive fender stamping die processes and cut the manufacturing cost of automobile fender, the fender of an SUV was taken as the research object. Based on the analysis of product stamping technology, a three-process stamping scheme using process integration technology was proposed. By combining the side punching and side flanging-shaping and adopting the primary side shaping process for large angle and long flange flanging, the same sequence of different process contents, including wing side punching, side flanging, side shaping and so on, was realized. The structure of flanging-shaping die meeting the three-process requirements of fender was introduced, and the structure layout and working principle of three different types of special-wedge mechanisms were described. Finally, the industrial application of three-process fender was completed and the requirements for mass production was achieved. The results show that the three-process stamping scheme can effectively shorten the fender stamping process, and greatly reduce the production cost of fender. |
