Title: Hajime Yoshida: Innovator in Die Cushion Technology
Introduction
Hajime Yoshida is a notable inventor based in Komatsu, Japan. He has made significant contributions to the field of pressing technology, particularly through his innovative die cushion devices. With a total of 2 patents, his work has enhanced the efficiency and accuracy of pressing operations.
Latest Patents
Yoshida's latest patents include a die cushion device and a pressing machine equipped with this device. The die cushion device features a unique design where a die cushion pad is divided into four small pads and one large pad. This configuration allows for the equalization of loads applied to the small pads, effectively canceling any overturning moments that could lead to flexure. As a result, the risk of friction between the cushion pin and the bolster's penetrating hole is minimized, facilitating smoother lifting operations and achieving higher accuracy in pressing forming operations.
The pressing machine, which incorporates the die cushion device, consists of a bed and a bolster. The bed contains an inner space where the die cushion pad can move up and down. A supporting portion penetrates the die cushion pad, providing support to the bolster and preventing flexure during press forming operations. This innovative arrangement simplifies the design by eliminating the need to divide the die cushion pad, thus avoiding complications.
