A Study on the Development of Practical and Adaptive Progressive Die for Very Thick Sheet Metals

후판재료에 대한 실 적응성 프로그레시브 금형 개발에 관한 연구

In the field of design and making tool for press working, the progressive die for very thick sheet metal(SS41, 4mm) is a specific division. In order to prevent the defects, the optimum design of the production part, Strip layout, die design, die making and tryout etc. are necessary. They require analysis of many kinds of important factors, i.e. theory and practice of metal working process and its phenomena, die structure, machining condition for die making, die materials, heat treatment of die component, know-how and so on. In this study, we designed and constructed a progressive die of multi stage and tried out through the I-DEAS, DEFORM, and CAD/CAM application. Out of these processes, the die development could be taken advanced technology. Especially the result of try out and its analysis become to the characteristic of this study.
