Title: The Innovative Contributions of Masahide Sunata
Introduction
Masahide Sunata is a notable inventor based in Komatsu, Japan. He has made significant contributions to the field of pressing technology, holding a total of 3 patents. His inventions focus on enhancing the efficiency and accuracy of pressing operations.
Latest Patents
One of his latest patents is the Die Cushion Device. This innovative device features a die cushion pad that is divided into four small pads and a large pad. This arrangement allows for the equalization of loads applied to the action points of the small pads by the large pad. Consequently, it cancels out any overturning moments that could lead to flexure of the small pads. This design prevents friction between the cushion pin and the penetrating hole of a bolster, ensuring smooth lifting operations and higher accuracy in pressing forming operations.
Another significant invention is the Pressing Machine with Die Cushion Device. This machine includes a bed that houses the die-cushion device and a bolster positioned on the bed. The bed has an inner space where the die-cushion pad can move up and down. A supporting portion penetrates the die-cushion pad, supporting the lower surface of the bolster via a carrier. This design prevents flexure of the bolster during press forming operations, allowing for highly accurate results. Additionally, the need to divide the die-cushion pad is eliminated, simplifying the overall arrangement.
