Title: Haruo Meguro: Innovator in Crankshaft and Cold Working Technologies
Introduction
Haruo Meguro is a notable inventor based in Saitama, Japan. He has made significant contributions to the field of mechanical engineering, particularly in the development of methods for forming crankshafts and other metallic articles. With a total of 3 patents to his name, Meguro's work has had a lasting impact on manufacturing processes.
Latest Patents
One of Meguro's latest patents is a method for forming a crankshaft. This innovative process involves producing a shaped metallic article from a commercially available hollow pipe. The hollow pipe, which has a predetermined wall thickness, is squeezed into a hollow blank pipe with a specific shape and wall thickness. A region of the hollow blank pipe is then heated, allowing it to be upset and bent into a crankshaft. The process utilizes dies positioned on either side of the gripped portion of the blank, along with punches, to achieve the desired shape. After forging the crankshaft, one of the punches is released before the dies are separated.
Another significant patent by Meguro is related to a successive cold working process. In this method, a billet is cold worked into products such as countershafts or outer races for constant-velocity joints. The process begins with forming a chemically converted lubricating coating on the billet's surface. The billet is then forged into an intermediate product at a temperature below its transformation temperature. Following this, the surface of the intermediate product is covered with lubricating oil in a die cavity, and it is forged again at a temperature below the transformation temperature before it gains predetermined hardness due to age hardening.
