Title: Akihide Yoshitake: Innovator in Welding and Metal Forming Technologies
Introduction
Akihide Yoshitake is a prominent inventor based in Tokyo, Japan. He has made significant contributions to the fields of welding and metal forming technologies. With a total of 3 patents to his name, Yoshitake's innovations have advanced manufacturing processes in various industries.
Latest Patents
One of his latest patents is an indirect spot welding method. This method is designed for welding members that include at least two overlapping steel sheets with a ferrite phase as the main phase. The process involves holding a welding electrode against a steel sheet from one side while applying pressure. A feeding point is attached to the steel sheet at the opposite side, allowing current to flow between the electrode and the feeding point. This technique includes contacting magnetic rigid bodies to the peripheral area of the electrode, securing the overlapping region by a magnetic force, and achieving a weld with satisfactory strength.
Another notable patent is a press forming method for metal sheets and frame parts for automotive bodies. This method utilizes dies with a surface roughness of an arithmetical mean roughness Ra of 7.5 μm or smaller. Fluid with a kinematic viscosity of 500 mm/s or lower is supplied to various spaces between the metal sheet and the dies. The die can be detached from the workpiece during the forming process, allowing for resumption of the forming.
