Latest Patents

Hirota holds a patent for a "Steering rack and method of manufacturing the same." This invention involves a unique process where a punch is pressed downward, causing the inner circumferential surface of a first rack blank to bite into the top surface of a second rack blank. This method allows the blank material to flow upward due to a reaction force, which is utilized to form rack teeth. The design ensures that a gap is left between the two blanks, preventing the die from being sealed and thereby reducing the forming load. This innovation not only extends the lifetime of the die but also increases the rigidity of the entire rack teeth.
