The application for the patent was published on Aug. 29, under issue no. 35/2025.
According to the abstract released by the Intellectual Property India: "This method for manufacturing a press-formed article (10) includes a forming step and a burring step. In the forming step, a material (M) is placed between a first die (21) and a second die (22), and the dies (21, 22) are brought relatively close to one another to clamp and form the material (M) by means of a first forming surface (211) and a second forming surface (221). In the burring step, a piercing punch (23) is caused to project from the first forming surface (211) while the material (M) is being sandwiched between the forming surfaces (211, 221), to form a through-hole (123) in the material (M). In the burring step, a burring punch (24) is then caused to project from the first forming surface (211) to raise an outer peripheral portion of the through-hole (123), while the material (M) is being sandwiched between the forming surfaces (211, 221), to form a burred portion (12) in the material (M)."
The patent application was internationally filed on Dec. 18, 2023, under International application No.PCT/JP2023/045182.
