Title: Hiroyuki Fujii: Innovator in Forging Technology
Introduction
Hiroyuki Fujii is a notable inventor based in Chiryu, Japan. He has made significant contributions to the field of forging technology, holding a total of 3 patents. His innovative approaches have led to advancements that improve manufacturing processes and reduce costs.
Latest Patents
Fujii's latest patents include a forging method and forging apparatus designed to enhance the dimensional precision of forged articles. This method minimizes machining processes, thereby reducing overall costs. The process involves placing a workpiece inside a die and pressing it in the axial direction, allowing the material of the end face to flow into a recessed or projecting shape. This forging method is characterized by the use of independent pressing and holding means, which allows for precise control during the press forming.
Another significant patent is the method of manufacturing a fuel injector core. In this process, a block of material is prepared from a bar or coil using clamp shearing with a working fluid that contains an extreme-pressure additive. This additive forms a protective layer on the cut-off surface, preventing material from seizing during cold forging. The block is then cold forged to create a wall that defines a fuel passage, showcasing Fujii's innovative approach to manufacturing.
