Abstract

Bent products have recently been applied widely in various structures. The method of sharp bending has the advantage of producing bent products with a fine appearance. Meanwhile, it has been recently shown that origami forming can be applied as a free manufacturing method that creates a fine appearance using complex folding lines. Sharp bending and origami forming both require folding lines. Folding lines are produced to make a V-groove before bending. Cutting V-grooves for folding lines requires machining center plants and long working times, which are not suitable for mass production. This paper presents newly developed and convenient V-shaped punch tools for folding line processing in sharp bending and origami forming. As a result, origami forming is expected to be adopted as a press method using V-shaped punch tools. Additionally, this paper reports on the findings of deformation behavior and mechanism obtained in experiments on folding line processing. The investigation for three-dimensional plate deformation around the V-shaped punch terminal shows extended folding line by terminal effect. Phenomena and the required load of V-shape punch indentation are considered in determining the mechanism of V-shape punch indentation from the results of finite element analyses and experiments on groove formation using V-shaped punch tool system.
