Research on advanced progressive die forming for small batch production of medical forceps and their functional progresses

研究了医用镊子的模具成形工艺。通过试验和分析，研究了冲压成形工艺，该工艺注重小批量生产，模具和导销系统小型化，产品精度高。在本研究中，一对夹持器被部分定位为镊子的典型组件。研究结果表明，重复级进模成形技术适用于小批量生产和模具小型化。此外，还阐明了导销在成形过程中的行为。

Die-mould technique for forming medical forceps is studied. Press forming technology, focusing a small batch production, miniaturization of die-mould and pilot pin system lead to high preciseness of the products, is investigated through experiments and analysis. In the study, a pair of gripper is part targeted as a typical component of the forceps. As the results, repetitive progressive die forming developed is applicable for the small batch production and miniaturization of die mould. Furthermore, behavior on pilot pin during forming is also clarified.
