型材制造需求的不断增长导致型材的几何复杂性不断增加。如今,轻量化设计和负载适应是非常重要的,需要新的型材制造技术。为了科普这一发展趋势,人们发明了一种新的管材成形方法--增量成形法(IPF)。IPF允许灵活制造具有沿纵向型材轴线沿着变化的横截面几何形状的型材,因此为制造轻质设计部件提供了很大的潜力。由于高度的创新,有关工艺基础和工艺限制的研究工作是必要的。出于这个原因,第一个基本的实验和数值研究的结果。而在实验中,该工艺的潜力显示在可行性研究中,首先分析了成形过程,并在数值研究中进行了不同的工艺参数对该工艺的影响。特别是,事实证明,工具进给和管尺寸对成形力有显着的影响,而工具半径的影响很小。
Increasing demands in profile manufacturing leads to a constant increase of the geometric complexity of the profile. Nowadays, lightweight design and load adaption are of huge importance and a need for new profile manufacturing technologies exists. In order to cope with this development, a new tube profile forming method was invented, the incremental profile forming (IPF). IPF allows the flexible manufacturing of profiles with varying cross section geometries along the longitudinal profile axis and offers therefore a high potential for the manufacturing of lightweight design parts. Due to the high degree of innovation, research work regarding the process fundamentals as well as the process limits is necessary. For this reason, the results of the first basic experimental and numerical investigations are presented. While in the experiments, the potential of the process is shown in feasibility studies, first analyses of the forming process, and the influence of different process parameters on the process were carried out in numerical investigations. In particular, it turned out that the tool infeed and tube dimensions have significant influence on the forming force, whereas the tool radius has a minor influence.
