Patent ID: 10807137

Abstract:
A method for producing a press-formed product that includes a pair of flat sections and a bend section that connects the flat sections, in which a bending radius of the bend section is R2 and an interior angle formed by the pair of flat sections is θ2, includes the steps bellow. In the first forming step, an intermediate formed product including a bend section in which a bending radius is R1 and an interior angle is θ1 is formed. In the second forming step, a portion of a bend section of the intermediate formed product is formed into the bend section of the press-formed product. R1, θ1, R2 and θ2 satisfy the conditions of Formulae (1) to (3) below: 1.05<A1/A2  (1);1.0<R1/R2  (2);A1/A2<6.0/(R1/R2)  (3),
