U形汽车冲压件简化模型的构建

Construction of Simplified Model of U-shaped Automobile Stamping Parts

近年来汽车工业发展迅速,新车上市速度越来越频繁,高强钢在汽车冲压件中的应用变得更加广泛。对比了2种汽车冲压件简化模型,提出了U形简化模型的合理性。结合生产实际,构建出了1个U形汽车冲压件简化模型。根据该模型选取热冲压高强钢22MnB5作为冲压材料,进行计算模拟,验证了这个U形汽车冲压件简化模型的可行性。研究表明:采用U形汽车冲压件简化模型科学合理,构建出的U形汽车冲压件简化模型符合需求,可用于指导实际汽车冲压件生产。

With the rapid development of the automobile industry in recent years, the new car market is be- coming more and more frequent, and the application of high strength steel in the automobile stamping part becomes more extensive. The rationality of U shape model was proposed by comparing with two kinds of automobile stamping parts. Combining with the production practice, a simplified model of U shaped auto- mobile stamping parts was built. According to this model, the hot stamping high strength steel 22MnB5 was selected as the punching material, and the simulation was carried out to verify the feasibility of the U shaped automobile stamping parts. The result shows that the simplified model of U shaped automobile stamping is reasonable and scientific. The simplified model of U shaped automobile stamping parts meets the requirements, which can be used to guide the production of the actual automobile stamping parts.
