Title: The Innovations of Masao Nishihara
Introduction
Masao Nishihara is a notable inventor based in Kyoto, Japan. He has made significant contributions to the field of metalworking through his innovative patents. With a total of 5 patents, Nishihara has developed methods that enhance the efficiency and effectiveness of metal extrusion and cold-working processes.
Latest Patents
One of his latest patents is an "Extrusion method using hot lubricant." This method involves hot lubricated metal extrusion, where a billet is extruded into a solid or tubular form using a die and/or a mandrel. An organic lubricant is interposed within a container, and a combustion improver or a mixture of a combustion improver and water is fed into the extruded product. This process effectively burns off the carbide of the lubricant deposited on the surfaces of the extruded product. Another significant patent is the "Method and apparatus for cold-working annular workpieces." This invention describes a method and apparatus that apply internal fluid pressure to cold-work annular workpieces, causing an enlargement of their diameter through plastic deformation. The openings at opposite ends of the workpiece are closed by presser plates, and the contacting surface pressure is controlled by an arithmetic unit.
