Latest Patents

Ueda holds a patent for a "Method of forging flanged shaft." This forging method is designed to produce a flanged shaft, such as a crankshaft, which features a flange at its intermediate portion. The process involves using a blank that has a smaller diameter than the shaft end portions, yet is sufficiently large to prevent buckling during axial compression. The blank is placed within a closed die apparatus and is axially compressed by a punch. This method allows for high dimensional precision and yield while minimizing the time and labor required for finishing work, all without the need for a large-size press.
