There is provided a die device capable of reliably releasing a workpiece from a die even when the workpiece has an undercut, and conveying the workpiece to a next process. A die device including: a lower die; and a lifter that lifts a pressed workpiece from the lower die, the lower die having an undercut region which is a portion that interferes with the workpiece when the workpiece is moved along a press direction, the lifter including: a vacuum cup that comes into contact with the workpiece; a rod part having a distal end provided with the vacuum cup; and a linear drive servomotor for causing the rod part to advance/retreat in an axial direction, and further including a rotary drive servomotor that turns the lifter in a direction orthogonal to the axial direction, wherein the lifter moves the workpiece by combining both movement along the press direction and movement in a direction inclined to the press direction.

A progressive pressing method includes: a first bead molding step of molding a first bead having a length of a second predetermined distance extending in a longitudinal direction of the elongated metal plate, in a side part of a region which becomes a first product part of the elongated metal plate; a first conveying step of conveying the elongated metal plate in the longitudinal direction by a feed amount which is a first predetermined distance; and a second bead molding step of molding a second bead having a length of the second predetermined distance extending in the longitudinal direction of the elongated metal plate, so as to link with the first bead molded in the first bead molding step, in a side part of a region which becomes a second product part of the elongated metal plate, in which the second predetermined distance is longer than the first predetermined distance.

In a progressive pressing device, a first state of a lifting part is a state not sandwiching an elongated metal plate between a lifting plate and an upper plate in a state in which a positioning pin and a positioning hole are not engaged, a second state is a state not sandwiching an elongated metal plate between a lifting plate and an upper plate in a state in which a positioning pin and a positioning hole are engaged, and a third state is a state sandwiching an elongated metal plate between a lifting plate and an upper plate in a state in which a positioning pin and a positioning hole are engaged.

The present invention provides a hot-stamping formed article which is long and formed of a single steel sheet, the hot-stamping formed article including: two standing wall portions; a top sheet portion adjacent to the two standing wall portions; and a protrusion portion including an overlapping portion in which a portion of the steel sheet extending from at least one standing wall portion of the two standing wall portions and a portion of the steel sheet extending from the top sheet portion overlap, in which an angle between the top sheet portion and the protrusion portion in a case where a plane perpendicular to a longitudinal direction of the hot-stamping formed article is viewed in a cross section is larger than 90°.

The underlying invention relates in particular to a production module for a production line which is modularly populatable with production modules. In embodiments, provision is made whereby the production module comprises at least one manipulator unit with which a workpiece or a workpiece component is, during the production process, transferable between a deposit position and a production position in the production space of a production module which, for the execution of a production step, is positioned directly downstream in a production direction (R) along the production line.

A metal sheet for press forming has a shape such that a boundary position between the region corresponding to the curved portion and an other region in the region corresponding to a curved portion is rotationally displaced in-plane around a rotational center set at a position on a curved recessed side rather than a position corresponding to a ridge line between a top sheet portion and a vertical wall portion on the curved recessed side, in a direction in which a line length of an outer edge of a position to be formed into the flange portion on a curved protruding side in the region corresponding to a curved portion approaches a line length of an outer edge of the flange portion on the curved protruding side in the press-formed component shape.

A method includes press forming a metal sheet into an intermediate formed product bent out of a plane and forming into a desired press-formed component shape. In a region to be a flange portion, an angle to be bent out of the plane is equal to or less than an angle formed by the flange portion at the curved portion in the press-formed component shape. The projection portion has a largest projection height at the center portion in the longitudinal direction of the region to be the curved portion as seen in the side view, and a longitudinal length of a region to be the top sheet portion is set to coincide with or approach a longitudinal length of the top sheet portion in the press-formed component shape.

A tight space pilot, tight space pilot assembly, and related method includes a tight space pilot that can be installed into a die without fasteners, fastener apertures, or added blocks for mounting. The tight space pilot assembly includes ejectors that are retained by the pilot and a retaining ring that holds the tight space pilot in place in a die member.
