  • Press-forming apparatus, method for producing press-formed product using the forming apparatus, and press-formed product
    Patent number: 10406582
    Abstract: A press-forming apparatus is an apparatus for producing a press-formed product having a hat-shaped cross section that has an external shape that curves in an L shape along a longitudinal direction in a planar view, and includes a punch, a first blank holder, a second blank holder, a preceding portion, a second die and a pad. When pushing the punch into a die to form a metal plate into the press-formed product, a first guide face of the preceding portion precedes a second guide face of the second die, and thereafter sliding of the first blank holder and the preceding portion relative to the punch is restricted and pushing of the punch into the die is continued in the restricted state to form the press-formed product. By this means, the press-formed product in which cracks and wrinkles are reduced is obtained.
