Title: Suekazu Nakashima: Innovator in Press Technology
Introduction
Suekazu Nakashima is a notable inventor based in Tokyo, Japan. He has made significant contributions to the field of press technology, holding a total of 2 patents. His work focuses on improving processing accuracy and efficiency in manufacturing.
Latest Patents
Nakashima's latest patents include a press machine and a method of manufacturing pressed products. The first patent aims to reduce mutual interference between multiple sets of molds coupled to a common frame stand, thereby enhancing processing accuracy. This innovation utilizes servo motors that are individually controlled by servo amplifiers. The control portion in the servo amplifier calculates the current to ensure that the measured value of the rotating position of the servo motor follows a directing value sent from a CPU. Additionally, a torque detecting and limiting portion ensures that the calculated current does not exceed a specified limit value, thus maintaining operational integrity.
The second patent focuses on a press apparatus and a press controlling method that applies press working to processed objects with accurate press load. This invention is designed to mitigate the effects of variations in thickness of the processed objects and variations in shut height of molds. A servo motor is connected concentrically to a rotation transmitter, converting the driving force into a thrusting force for the press ram. This ensures that the correct press load is applied, preventing issues during the press processing.
