Latest Patents

One of Sakurai's latest patents is for an aluminum alloy sheet with excellent post-fabrication surface qualities and a method of manufacturing the same. This invention discloses an Al-Mg-Si aluminum alloy sheet that can prevent ridging marks during press forming. It also ensures good reproducibility even under stricter fabricating conditions. The patent outlines a specific composition for the aluminum alloy sheet, where hot rolling is performed based on a set relationship between the rolling start temperature and the rolling finish temperature. This method helps to make the cube orientation distribution profile more uniform, thereby suppressing the appearance of ridging marks during sheet press forming.

Another significant patent is for a press forming method for aluminum alloy sheets and a pressing device. This invention provides a method capable of forming large panels, such as automobile body outer panels, which are often difficult to shape. The method involves using two punches that can shift independently, allowing for the formation of non-contact outer peripheral parts of the sheet until the vicinity of the bottom dead point.
