State-of-the-art of plate forging in Japan

Production Process

Abstract

The state-of-the-art of plate forging processes for forming complicated parts without cutting and finishing in Japan was reviewed. For cups having comparative large thickness and plates having complicated cross-sectional shapes, plate forging is more useful than conventional billet forging due to due to comparatively small change in shape. In plate forging, forging processes such as upsetting, extrusion and ironing are included in the sequence of conventional stamping composed of shearing, bending and deep drawing in order to control metal flow in plates. Plate forging has the advantages of higher performance, larger productivity, lower cost, etc. Plate forging processes are classified into desired functions of products, local thickening, local thinning, formability improvement and forming of gears and plates.
