  • Research on the forming of tailored blanks in conventional tools
    Pepelnjak, Tomaž ...
    The introduction of modern manufacturing concepts and technologies is an important factor in the development of new product and the redesign of existing ones. This paper explors the setting up of a ... system for the manufacturing of modular sheet matal products, from an idea to the salesman, with emphasis on those segments of the system in which laser techology and metal forming are linked - that is, tailored blanks. For the introduction of the latter it is usually necessary to design and make completely new tools which, for large sheet metal products, are very expensive. The paper presents the searching for compromises in the forming of tailored blanks on existing conventional tools for deep drawing of sheet matal products. The use of tailored blanks on tools for the forming of sheet metal products from one piece blanks is interesting above all for redesigning of products, if the production of a new tool is not cost-efficient. By connecting basic tests (experiments) and comperative computer FEM models, the first guidelines for the use of existing tools for the forming of tailored blanks were determined. The guidelines for the use of tailored blanks in conventional (existing)tools were verified in practice on an example of an internal wall of the doors and the cabinet of a stove oven, both produced from sheet metal of different thicknesses.
