Title: Youichi Konkawa: Innovator in Press Forming Technology
Introduction
Youichi Konkawa is a notable inventor based in Nasukarasuyama, Japan. He has made significant contributions to the field of press forming technology, holding a total of 2 patents. His innovative designs focus on improving the efficiency and quality of press-formed articles.
Latest Patents
Konkawa's latest patents include a press form device and method for producing press-formed articles. This invention features a punch and a pad that sandwich a top sheet portion, along with bending blades for bend-forming vertical wall portions. The design incorporates stoppers that face the bending blades, ensuring precision during the forming process. The punch is supported by a first cushion component, while the bending blades consist of upper and lower die components that maintain a specific interval during operation. This interval is crucial for achieving the desired compression amount, which ranges from 2% to 6% of the heights of the vertical wall portions. Additionally, a second cushion component is interposed between the upper and lower die components, allowing for controlled contraction in the press direction. The unique cushion pressure of the second component prevents it from contracting during the bend-forming process, thereby reducing warping and buckling of the vertical wall portions.
