Takeaki Sato

Title: Takeaki Sato: Inventor in Plastic Working Technology

Introduction

Takeaki Sato is an inventor based in Kasugai, Japan. His patent work includes methods and apparatus for plastic working, including forging processes that shape a workpiece through controlled die movement. Sato is associated with Brother Kogyo Kabushiki-Kaisha and holds 3 patents.

Latest Patents

One of Sato’s latest patents describes a plastic working method and apparatus that uses partial pressing contact between a die and a workpiece. The die moves in a swinging or circular rocking motion while a mechanism shifts the workpiece and die relative to one another within the swing plane. This approach enables plastic working, such as forging, to follow the shape of the die’s molding surface.

Another patent describes a plastic working apparatus in which an upper die swivels on a die holder, with a toggle mechanism providing power assistance. Upper and lower double-eccentric rotary mechanisms support the die holder and allow its orientation to change. A link positioned within the holder connects the machine frame to the holder, and its orientation can also be adjusted.

Career Highlights

Sato’s disclosed inventions focus on improving the movement and control of dies during plastic working. His work combines swinging or swiveling die motion with mechanisms that adjust the relative position and orientation of the tooling.

Collaborations

Sato is associated with Brother Kogyo Kabushiki-Kaisha. His listed coworkers include Kunio Hirota and Syozo Aoshima.

Conclusion

Takeaki Sato’s patent portfolio reflects a focus on die-motion mechanisms and plastic working methods designed to shape workpieces through controlled, adaptable tooling.
