Latest Patents
One of Nakagawa's latest patents is a hydraulic press designed for forming metal plates. This hydraulic press features closed loop feedback control on a slide, slide pad, and bolster cylinders. The hydraulic cylinders actuating various components of the press are controlled based on ideal position estimates, ensuring consistent and precise pressing action. The closed loop control system includes an ideal position/pressure value generator, a position/pressure detector, and an arithmetic unit that compares the ideal and actual position/pressure values. This comparison allows the arithmetic unit to produce a control signal that drives a cylinder to the desired position or pressure. The hydraulic press is capable of performing multiple operations on a workpiece in a single press cycle, which is a significant improvement over traditional presses that require several operation steps or die changes. Additionally, the bolster cylinders enhance clamping force, reduce shock, and improve die alignment, resulting in better outcomes with less wear on press components. Another notable patent is an injection molding method with compression for hardening.
