Abstract
Provided is a method for manufacturing a press-molded part, the method including: forming an intermediate product by press molding; and forming the press-molded part by performing press molding on the intermediate product. The intermediate product includes: a top panel; a pre-vertical wall; a pre-lateral wall; a pre-bottom wall; and an outward bulge. The press-molded part includes: the top panel; a vertical wall; a lateral wall; a bottom wall; a first ridge line; a second ridge line; a third ridge line; and a convergence portion. The outward bulge is a plate-like portion contiguous with the pre-vertical wall, the pre-lateral wall, and the pre-bottom wall. The outward bulge is deformed by press molding, thereby forming the press-molded part from the intermediate product.
Claims10
A method for manufacturing a press-molded part, the method comprising:
- a step of forming an intermediate product by performing press molding on a plate-like shaped material;
- and
- a step of forming a press-molded part by performing press molding on the intermediate product,
- wherein the intermediate product comprises:
- a top panel with a plate-like shape, including a vertical edge and a lateral edge;
- a pre-vertical wall with a plate-like shape, extending from the vertical edge of the top panel of the intermediate product;
- a pre-lateral wall with a plate-like shape, extending from the lateral edge of the top panel of the intermediate product;
- a pre-bottom wall with a plate-like shape, being contiguous with the pre-vertical wall and the pre-lateral wall;
- and
- an outward bulge with a plate-like shape, being contiguous with the pre-vertical wall, the pre-lateral wall, and the pre-bottom wall,
- wherein the press-molded part comprises:
- a top panel with a plate-like shape, including a vertical edge and a lateral edge;
- a vertical wall with a plate-like shape, extending from the vertical edge of the top panel of the press-molded part;
- a lateral wall with a plate-like shape, extending from the lateral edge of the top panel of the press-molded part and being contiguous with the vertical wall of the press-molded part;
- a bottom wall with a plate-like shape, being contiguous with the vertical wall of the press-molded part and the lateral wall of the press-molded part;
- a first ridge line to form a boundary between the vertical wall of the press-molded part and the bottom wall of the press-molded part;
- a second ridge line to form a boundary between the lateral wall of the press-molded part and the bottom wall of the press-molded part;
- a third ridge line to form a boundary between the lateral wall of the press-molded part and the vertical wall of the press-molded part;
- and
- a convergence portion connected to one end of each of the first, second, and third ridge lines of the press-molded part,
- the bottom wall of the press-molded part protruding toward a bulging side of the press-molded part from the first ridge line, the lateral wall of the press-molded part protruding toward the bulging side of the press-molded part from the third ridge line,
- an outward bulge with a plate like shape, being contiguous with the pre vertical wall, the pre lateral wall, and the pre bottom wall,
- the outward bulge of the intermediate product being situated on a bulging side of the intermediate product relative to the first and third ridge line of the press-molded part and intersecting with a pre-second ridge line of the intermediate product that forms a boundary between the pre-lateral wall and the pre-bottom wall on the bulging side of the intermediate product relative to the convergence portion of the press-molded part, and
- wherein the outward bulge is deformed by press molding to form the press-molded part from the intermediate product.
