HOT FORMING AND VARIABLE THICKNESS STAMPING

摘要

PURPOSE: A hot-stamping molding method including thickness treatment is provided to manufacture a component which has locally different strength as a blank of regular thickness locally has different thickness by locally hot-rolling blanks. CONSTITUTION: A hot-stamping molding method including thickness treatment includes the following steps of: arranging a blank having regular thickness; and forming a shape of the blank by using a press device and reducing the thickness of a part of the blank by hot-rolling. The press device is divided into a hot-rolling press mold (210) and a cold-rolling press mold (220).
