讨论了车身用连续变截面辊轧板(TRB)在轧制和应用过程中的关键技术。TRB技术的实质是传统纵轧与辊间距实时调整变化相协调的过程,TRB轧制的关键是建立板厚综合系统控制模型,TRB在车身上的应用需要解决相应的冲压模具设计及冲压成型性评价等技术。该研究为实现车身轻量化拓宽了思路。
The key technologies of continuous variable cross-section rolled plate (TRB) for bodywork during rolling and application are discussed. The essence of TRB technology is the process of traditional vertical rolling and roll spacing real-time adjustment and adjustment. The key of TRB rolling is to establish the integrated control system of plate thickness. The application of TRB on the body needs to solve the corresponding stamping die design and stamping formability Evaluation and other technologies. The research broadens the thinking for lightweighting the body.
