摘要： Disclosed are a method and an apparatus for forging dissimilar materials by which dissimilar materials may be sequentially pressed after being introduced into and fixed to a tray plate that is moved above a lower mold so that the productivity of the product may be improved by continuously introducing the material even only by supplying a material plate. The apparatus includes a press having upper and lower molds, a tray plate supply unit that supplies a tray plate by one pitch from one side to an opposite side towards an upper side of the lower mold, punching parts that are provided on sides of the upper and lower molds to continuously form material passing/fixing parts in the tray plate, a material plate supply unit that is provided in front of the press to supply a material plate to the upper sides of the material passing/fixing parts by one pitch, cutting/pressing parts that are provided in the upper and lower molds at opposite sides of the punching parts to repeatedly cut the material plate introduced to upper sides of the material passing/fixing parts and fix the cut materials to the material passing/fixing parts after pressing the materials, pressing parts that are provided in the upper and lower molds at opposite sides of the cutting/pressing parts to press the moved materials, and extraction parts that are provided in the upper and lower molds at opposite sides of the pressing parts to separate and extract the formed materials.

摘要： A method of producing a press-formed product includes a steel plate heating step, a hot forging step and a hot stamping step. In the steel plate heating step, a steel plate is heated to 950°C or more. In the hot forging step, the heated steel plate is forged to form a varying-thickness steel plate. In the hot stamping step, the heated varying-thickness steel plate is subjected to press-working by a press tooling to form a press-formed product, and the press-formed product that is formed is cooled inside the press tooling. Thus, a press-formed product that has high strength and for which a reduction in weight is possible can be produced.
