Title: Masatoki Utsumi: Innovator in Press Control and Dust Collection Technologies
Introduction
Masatoki Utsumi is a notable inventor based in Toyota, Japan. He has made significant contributions to the fields of mechanical engineering and industrial technology. With a total of 3 patents, Utsumi has developed innovative solutions that enhance manufacturing processes and improve efficiency.
Latest Patents
One of Utsumi's latest patents is a "Method of and apparatus for controlling forming press conditions." This invention aids in maintaining stability in a mechanical double action press forming, which is equipped with an upper die and an outer ram. The dies are driven independently, allowing for automatic correction of press conditions, such as hydraulic and pneumatic pressure, based on feedback. This ensures that the conditions are maintained at preset values, even as the inner stroke changes during the forming process. Additionally, the system can detect and correct abnormal operations by continuously monitoring the press conditions.
Another significant patent is the "Discharge wire cleaning device for an electric dust collector." This device addresses the issue of dust accumulation on vertically arranged discharge wires. When dust builds up, compressed gas is ejected from a nozzle at the base of the wires, applying pressure to a skirt that drives it upward, effectively removing the dust. The design includes sliders that move down by gravity, and a damper may be added to ensure the slider can move up and down repeatedly. A brush on the slider further enhances the cleaning process by scraping off any remaining dust.
