Tailored blanks are widespread and gaining increasing use in the market with a competitive edge due to their load adaption, cost reduction through the efficient use of materials, and their lightweight design. In order to meet market demands and efficiently produce lightweight products, a new method is now developed to obtain strips with different thicknesses in the lateral direction, i.e., Rolled Profile Strips (RPS), by cold rolling. The new method includes bending-spreading rolling (BSR) and flattening rolling (FR). Experiments were performed to obtain RPS samples with a thickness ratio of 1:1.3. Then the deformation, metal flow, and stress-strain field in the BSR processes were simulated by FEM with ABAQUS software. The results indicate that the desired strips are obtained, whereby the thick areas undergo compressive deformation while the curved deformation area (thin area and transition areas) undergoes both tensile and compressive deformations. These findings will lay a foundation for the industrial application of RPSs.

量身定制的毛坯由于其负载适应性，通过有效使用材料降低成本和轻巧的设计而在市场上获得了广泛的应用，并具有竞争优势。为了满足市场需求并有效地生产轻质产品，现在开发了一种新方法以通过冷轧获得横向上具有不同厚度的带材，即轧制型材带（RPS）。新方法包括弯曲扩展轧制（BSR）和扁平轧制（FR）。进行实验以获得厚度比为1：1.3的RPS样品。然后利用ABAQUS软件通过有限元法对BSR过程中的变形，金属流动和应力-应变场进行了模拟。结果表明已获得所需的条带，由此，厚的区域经历压缩变形，而弯曲的变形区域（薄区域和过渡区域）经历拉伸变形和压缩变形。这些发现将为RPS的工业应用奠定基础。
