Hot press line and method of manufacturing hot-press-formed product

A hot press apparatus includes a first die partand a second die part, and a control unit. At least one of the first and second die partsandincludes a recessin the surface facing the other die part in the direction of pressing. A movable die partis provided in the recess. The control unitcontrols the movable die partsuch that the bottom-dead-center holding period, for which the first and second die partsandare at the bottom-dead center, includes an abutment period for which the movable die partabuts the metal sheet B and a non-abutment period for which the movable die part does not abut the metal sheet B.

Hot press apparatus and method of manufacturing hot-press-formed product

A method of manufacturing a press-formed product includes: capturing the sheet thickness of a sheet B; and using a die, a punch, and a movable mold part capable of moving relative to both the dieand punchto press-form the sheet B into a press-formed product. During press-forming, the initial position of the movable mold part relative to the dieor punchis controlled depending on the sheet thickness of the sheet B.

Method of manufacturing press-formed product and press line

The die includes a die base, a die body, and an opening/closing member. In the die base, a storage portion for storing refrigerant is formed. The die body includes a mounting surface, a forming surface, and a plurality of flow channels. The mounting surface is located on the storage portion side of the die base. The forming surface is located on the opposite side of the mounting surface. The flow channels pass through the die body from the mounting surface to the forming surface. The opening/closing member is disposed between the die base and the die body. The opening/closing member includes a plurality of through holes corresponding to the plurality of flow channels. The opening/closing member is configured to be movable with respect to the die base and the die body such that each of the through holes brings the corresponding flow channel and the storage portion into communication.

A frame structure of an automotive exterior panel includes a sheet-like outer panel, a plurality of first members, each of which has an elongated shape, and which are disposed on a vehicle inside with respect to the outer panel, and a second member that has an elongated shape and intersects with the plurality of first members, in which each of the plurality of first members extends in a first direction along a sheet surface of the outer panel, and has a groove part recessed from the vehicle outside toward the vehicle inside at a portion thereof in a longitudinal direction, the second member extends in a second direction along the sheet surface of the outer panel, and has a thickness in a vehicle inside-outside direction, which is uniform at a portion closer to the center than at both end portions in the longitudinal direction, and at an intersection portion where each of the plurality of first members and the second members intersect with each other, the second member is in contact with the inside of the groove part provided in each of the plurality of first members.
