在微片材成形中，尤其是在多阶段渐进成形操作中，以及特别是在必须保持一定的进料速率时，准确地进料是至关重要的。对薄金属板（< 100 μ m）的微成形的研究导致了对现有金属板送料器的性能的调查，关于它们的送料精度和可重复性。结果表明，追求更高的进给精度和重复性，这是针对5-15%的带厚度，是很难实现与商业可用的喂料机。为此，研制了一种用于微型板料成形的新型高精度高速送料装置。运动分析和进给仿真为进给器设计提供了支持。该馈线是与工业合作伙伴合作建造的。所进行的送料试验和成形实验表明，与现有的商业送料机相比，可以实现更高的送料精度和可重复性。这表明了一个有前途的解决方案，高精度带进给在微型板成形薄金属板进给。
Feeding the raw material accurately is essential in microsheet-forming, especially in multistage progressive forming operations and also when in particular, a certain feeding rate has to be maintained. Research into the microforming of thin sheet metals (< 100 mu m) led to investigations of the performance of existing sheet metal feeders, regarding their feeding accuracy and repeatability. The results indicated that the pursuance of greater feeding accuracy and repeatability, which was aimed at 5-15% of the strip thickness, was difficult to achieve with commercially-available feeders. A new high-precision and high-speed feeder was, therefore, developed for microsheet-forming. The feeder design was supported by motion analysis and feeding simulations. The feeder was constructed in collaboration with industrial partners. The conducted feeding tests and forming experiments demonstrated that greater feeding accuracy and repeatability can be achieved, compared to those of existing commercial feeders. This suggests a promising solution for high-precision strip feeding in microsheet-forming where thin sheet metals are to be fed.
