摘要： A method for manufacturing a hat-shaped cross-section component includes a gripping process, a bending and stretching process, and a bend back process. In the gripping process, a pair of vertical walls of an elongated preliminarily formed component that has been formed into a hat-shaped cross-section formed into a hat shaped cross section profile are disposed at a width direction outside of a punch, and a top plate of the preliminarily formed component is gripped using the punch and a pad. In the bending and stretching process, after the gripping process, a die provided on both width direction sides of the pad is moved toward the punch side relative to the preliminarily formed component, and the die is used to bend and stretch the vertical walls toward the opposite side to the top plate at one side in the length direction of the preliminarily formed component. In the bend back process, after the gripping process, a holder provided on both width direction sides of the punch is moved toward the pad side relative to the preliminarily formed component, and the holder is used to bend back the vertical walls toward the top plate side at another side in the length direction of the preliminarily formed component.

摘要： 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.

摘要： The invention provides technology for manufacturing a press component that has a hat shaped cross-section and that is curved in an L shape along the longitudinal direction using sheet metal having a tensile strength of from 500 MPa to 1800 MPa as stock, without generating creases or cracks, and achieving high yield. The top plate section of the metal stock is pressed and clamped against a punch 72 by a pad 74, a portion that will be at the outside of the L shaped curve is pressed and camped against a die 71 by a blank holder 73, a bender 75 is moved, and a vertical wall portion at the inside of the L shaped curved of the metal stock sheet and the flange portion joined to the vertical wall at the inside of the L shaped curve are molded. The metal stock sheet is moved in the direction toward where the blank holder 73 is positioned while maintaining a state in which the metal stock sheet is pressed and clamped against the die 71 by the blank holder 73, and a vertical wall portion at the outside of the L shaped curve of the L shaped hat shaped cross-section and the flange portion joined to the vertical wall at the outside of the L shaped curve are molded.
