Abstract

A successive forging process of tailored blanks having a thickness distribution supplied for hot stamping was developed. In this process, a blank having a uniform thickness was successively compressed with the upper and lower punches, simultaneously. Since local deformation was repeated in successive forging, the forging load is comparatively small, and tailored blanks without joining are produced similar to the tailor rolling process. The thickness was controlled only by the feed under a fixed stroke of the punch. As the feed decreases, the forging load decreases due to small contact area, and thus, the reduction in thickness of the blank becomes large for small elastic deformation of the press and tools. Tool marks appearing on the surface of the tailored blank were prevented by inserting concave and convex plates into a C-frame of a press. A tailored blank having two thicknesses was successively forged, and then hot-stamped into a roof rail.
