Title: Nobuyasu Nishihata: Innovator in Manufacturing and Forging Technologies

Introduction

Nobuyasu Nishihata is a prominent inventor based in Konan, Japan. He has made significant contributions to the field of manufacturing and forging technologies. With a total of 2 patents to his name, his work focuses on improving the efficiency and effectiveness of manufacturing processes.

Latest Patents

Nishihata's latest patents include a manufacturing apparatus for plate-like tooth profile members. This innovative apparatus addresses the problem of forging and forming in a single process using a closed-type die. It minimizes the occurrence of burrs due to plastic changes in both the circumferential and axial directions of the material. The design consists of an upper die and a lower die, with the lower die featuring a tooth die for forming the tooth portion of the material. The process involves two strokes: the first confines the circumference at both ends of the material, while the second forms the tooth portion.

Another notable patent is a forging method aimed at enhancing workability in machining. This method transforms the metallographical structure of products subjected to impact loads into a fine ferrite-perlite structure. It achieves a yield point exceeding that of traditional quenching and tempering methods while reducing tensile strength. The process involves heating a material with at least one group 5 metal added, forging it into the desired shape, and then cooling it in a controlled manner.
