JFE has been granted a patent for a press forming method to create a hat-shaped cross-section product. The method involves forming a preformed part with a twisted side wall portion and concave curve, then press-forming it into the final product. The twisted side wall is twisted to a specific angle for optimal results. GlobalData’s report on JFE gives a 360-degree view of the company including its patenting strategy. Buy the report here.

Press forming method for hat-shaped cross section products
A press forming method for creating a press-formed product with specific features has been granted a patent (Publication Number: US11998968B2). The method involves a two-step process: first, press-forming a blank into a preformed part with a twisted side wall portion and a concave curved portion, and second, press-forming the preformed part into the final product. The twist in the side wall portion is strategically designed to have a smaller angle at the end portion compared to the longitudinal center of the concave curved portion. Additionally, the torsion amount of the twisted side wall portion is calculated using a specific equation, ensuring it falls within a range of 10° to 20°.
This innovative press forming method aims to produce press-formed products with a web portion, side wall portion, flange portion, and concave curved portion that are intricately shaped and interconnected. By carefully controlling the twist in the side wall portion during the forming processes, the method allows for the creation of complex geometries with precision. The calculated torsion amount ensures that the twisted side wall portion meets specific dimensional requirements based on the side wall height and longitudinal length, contributing to the overall quality and structural integrity of the press-formed product.
