Title: Masatoshi Sawamura: Innovator in Powder Compaction and Gear-Rolling Technologies
Introduction
Masatoshi Sawamura is a notable inventor based in Aichi-ken, Japan. He has made significant contributions to the fields of powder compaction and gear-rolling technologies. With a total of 2 patents, his work has advanced manufacturing processes in various industries.
Latest Patents
One of Sawamura's latest patents is a method of forming a powder compact. This invention provides a technique that produces a high-density compact under high pressure while reducing the pressure needed for ejecting the compact from a die. The method involves applying a higher fatty acid lubricant to the inner surface of a heated die, followed by filling the die with metal powder and compacting it. This process results in a metallic soap coating that decreases friction and allows for easier ejection of the compact.
Another significant patent is the process for gear-rolling a high accuracy gear. In this invention, the outer circumferential portion of a disk-shaped workpiece is heated to high temperatures. The heated workpiece is then formed using a roller die to create a rolled gear with teeth. The process includes specific temperature ranges for both the hot rough-rolling and warm finish-rolling steps, ensuring high accuracy in the final product.
