对资源高效工艺的需求给冷锻行业带来了新的挑战。目前的趋势要求零件具有更高的材料效率，从而实现更小的质量。为了实现这一要求，需要使用高强度钢和复杂的几何形状。但是，由这些发展产生的更高的工艺力导致工艺载荷增加，从而导致弹性工具以及压力机变形。详细和广泛的工具载荷的数值确定，使他们的减少负载相关的形状优化的工具的几何形状。本文的目的是基于有限元/边界元方法建立一个高效、精确的侧向挤压过程仿真模型。
The need for resource efficient processes leads to new challenges in cold forging industry. Current trends demand parts with less mass enabled by a higher material-efficiency. To achieve this requirement, high strength steels and complex geometries are used. But, the higher process forces arising from these developments lead to increasing process loads and thus elastic tool as well as press deformations. A detailed and extensive numerical determination of tool loads enables their reduction by a load-dependent shape optimization of the tool geometry. Aim of this work is a time-efficient and precise process simulation modeling the press-tool-workpiece interaction for a lateral extrusion process based on an integrated FEM/BEM method.
