摘　　要：为从材料成本控制角度降低冲压成本,从材料利用率提升、钣金制造新工艺应用、合理选材3个方面,结合具体的应用案例,探讨了汽车冲压材料成本的控制策略。首先,针对材料利用率可从产品协同开发、冲压工艺优化及冲压废料再利用3个方面进行提升。其次,钣金制造新工艺方面可采用辊压、集成式热成形等工艺代替单件冲压或多件单独冲压后点焊的工艺。最后,针对合理选材,给出了同强度钢材选择原则、烘烤硬化钢代替无间隙原子钢和高强度钢的应用建议。In order to reduce stamping cost from perspective of material cost control,this article discussed the cost control strategy for automotive stamping material from three aspects:improving material utilization rate,applying new sheet metal manufacturing processes,and selecting materials rationally,combined with specific application cases.Firstly,material utilization can be improved by product collaborative development,stamping process optimization,and reusing stamping waste materials.Secondly,in the application of new sheet metal manufacturing processes,processes such as roller pressing and integrated heat forming can be used to replace the process of single stamping or multiple separate stamping followed by spot welding.Finally,in terms of rational material selection,principles for selecting steel with the same strength,using bake-hardening steel instead of interstitial-free steel,and recommendations for the application of high-strength steel are provided.

关 键 词：材料成本 材料利用率 产品协同 工艺优化 合理选材
