プレス成形部品及びその製造方法
Document Type and Number:
Japanese Patent JP6881691
Kind Code:
B2
Abstract:
Provided are a press formed component that does not easily cause wrinkling on a vertical wall portion of a curved portion in a component shape having an L-shape, a T-shape, or the like when viewed in a plan view and a method for manufacturing the same. A press formed component (20) includes a top sheet portion (1), a vertical wall portion (2) continuous to the top sheet portion (1), and a flange portion (3) and also includes a curved portion (4) in which when viewed in a plan view, at least a part of a boundary portion (5) between the top sheet portion (1) and the vertical wall portion (2) is displaced to the vertical wall portion (2) side and curved concavely toward a longitudinal direction. In a cross-sectional shape of the curved portion (4), an inclination angle θ [deg] of the vertical wall portion (2) with respect to the top sheet portion (1) satisfies expression (1) below: 1−sinθ/cosθ>0.95
