Hidekazu OKABE has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).
Abstract: A press die includes a fixed die, a first movable die, and a second movable die to cut out a product from a metal plate member, and a scrap cutter to cut scrap that is not part of the product. A fixed-die cutting blade of the fixed die is configured to have a fixed-die cutting blade relief portion formed near a base end of the protruding scrap cutter and recessed inward to the product side from the cutting line of the product. The fixed-die cutting blade relief portion includes a substantially arc-shaped cross-sectional portion corresponding to a machining radius of a machining tool for forming the scrap cutter. A first movable-die cutting blade of the first movable die has a movable-die cutting blade protrusion to cut the metal plate member inward to the product side from the cutting line of the product.
