METHOD AND DEVICE FOR MANUFACTURING PRESSED COMPONENT
To produce an L-shaped pressed component without causing occurrence of wrinkles or cracks through first to third steps: the first step where a portion of a blank 8, having tensile strength of 1180 MPa or more, to be formed into a portion disposed outward of a curved portion is held in a state of bei...

| description | To produce an L-shaped pressed component without causing occurrence of wrinkles or cracks through first to third steps: the first step where a portion of a blank 8, having tensile strength of 1180 MPa or more, to be formed into a portion disposed outward of a curved portion is held in a state of being clamped by a blank holder 73 and a die 71, and a portion of the blank 8 to be formed into a top plate 11 is held in a state of being clamped by a pad 74 and a punch 72; the second step where a vertical wall 14, a concave ridge 17 and a flange 15 on the inner side of a curved portion 1a are formed by bend forming with a bending die 75, thus forming one, two or more material inflow promoting portion, which increases an inflow amount of the blank 8 flowing into a portion to be formed into the flange 15 on the inner side of the curved portion 1a, in the vicinity of a portion of the blank 8 to be formed into the flange 15 on the inner side of the curved portion 1a of the pressed component 1; and the third step where the die 71 is moved in a direction toward a side where the blank holder 73 is disposed so as to form a vertical wall 12, a concave ridge 16, and a flange 13 on the outer side of the curved portion 1a by draw forming. |
