Title
(EN) AUTOMOBILE BODY PRESS-MOLDED COMPONENT AND METHOD FOR PRODUCING SAME
(FR) COMPOSANT FORME A LA PRESSE DE CARROSSERIE AUTOMOBILE ET SON PROCEDE DE FABRICATION
Abstract
(EN)

An issue is to provide a member that exhibits high load capacity and
rigidity when joined to another member.
[Solution] Provided
is a member 1 having a transverse cross section that includes a
top sheet 2, upper ridgelines 4, vertical walls 3, lower ridgelines 5, and
floor flanges 9, and
including, on at least one end portions in the extending directions of the
upper ridgelines 4,
a top sheet flange 11 via a top sheet ridgeline 6 and vertical wall flanges 10
via vertical wall
ridgelines 7, in which the vertical wall flange 10 and the floor flange 9 are
continuous, and
in end portions of the upper ridgelines 4 and the lower ridgelines 5, the sum
total .SIGMA.R of the
radii of curvature of corner portions of the vertical walls and the sum total
.SIGMA.L of the widths
of the top sheet 2 and the vertical walls 3 in an end portion of the member
have the relation
of .SIGMA.R/.SIGMA.L <= 0.13. The member 1 is produced by performing a
first step of performing
press molding on a blank 26 to form, in a shrink flange manner, flange
ridgelines 8 and
thereby producing an intermediate molded product 27 including at least the
flange
ridgelines 8 and a second step of performing press molding on the intermediate
molded
product 27 to produce the member 1.
