Title: Innovations by Inventor Naoki Yoshioka

Introduction

Naoki Yoshioka is a prominent inventor based in Okazaki, Japan, recognized for his innovative contributions to hydraulic forming technology. With a total of three patents to his name, Yoshioka has significantly impacted the manufacturing processes used in various industries.

Latest Patents

Yoshioka’s latest inventions include a hydraulic forming process, a hydraulic forming device, and a metal separator for a fuel cell formed by hydraulic forming. His hydraulic forming device employs a method where a metal plate is placed on a support section with a hollow section filled with hydraulic fluid. The process involves lowering a blank holder to clamp the peripheral edge of the metal plate, followed by the upper die being lowered to deform the central section of the plate. This process generates increased fluid pressure, which transfers a rib-like convex section onto the metal plate body. After maintaining this pressure for a predetermined time, the fluid pressure is released, achieving the desired shape.

Furthermore, Yoshioka has developed a method for removing strain from a press-formed workpiece. This involves pressing a blank into a workpiece using upper and lower dies while clamping the peripheral edge with a blank holder. By partially holding the central portion, the method draws the peripheral section away, effectively eliminating strain.
