At least one of the first die and the second die is configured by assembling a plurality of die members. Each die member has a concave side surface facing another die member.

Abstract: A protruding portion is formed in a metal plate material by use of a plurality of molding tools each of which has a die and a punch. In a first step, an initial protruding portion is formed in the metal plate material by use of a first molding tool. In this step, a top of the initial protruding portion is formed to be thinner than other parts. In a second step, a sidewall of the initial protruding portion is rolled out by use of a second molding tool, and the protruding portion is formed.

Abstract: A metal plate stamping method is provided for cutting a metal plate, on which a bulging portion is formed through stamping, at a cutting area that is defined in a portion other than the bulging portion. The method includes forming a bead on the opposite side of the cutting area from the bulging portion and crushing the bead prior to the cutting of the metal plate.

Abstract: A separator for a fuel cell includes a thin metal plate, a protrusion formed on the thin metal plate, a gas passage formed by the protrusion, and a trap that is formed by forming a recess in a wall portion of the protrusion such that the trap is provided in the gas passage to correspond to the recess.

Abstract: A rotary lamination apparatus has a die assembly rotatable about an axis and a mounting table received in an axial hole extending through the die assembly. Through rotation of the die assembly, punched core pieces are mounted on the mounting table while being rotatively offset. A drive portion is employed to rotate the mounting table integrally with the die assembly about the axis of the die assembly.

Abstract: A recess is formed in a plate-like workpiece. Then, an inner ejector is engaged with the recess to restrict deformation of a body portion. In this state, a flange is formed in the outer periphery of the workpiece. A processed product portion is then punched out.

Abstract: Two press dies are formed by arranging a plurality of segments side by side to form die faces. The press dies are used to press a plate member. First and second joint portions are positioned differently between one of the press dies and the other of the press dies.

Abstract: A punched piece is formed by punching a metal plate by a punching portion including by a die and a punch. Before the punching, a preceding process portion provided in a stage previous to the punching portion forms a projection at an inner peripheral portion of a punch area of the metal plate that faces the die. Forming the projection cancels formation of shear droop at an edge of the punched piece in forming of the punched piece by punching of the metal plate.

Abstract: A rotary lamination apparatus has a die assembly rotatable about an axis and a mounting table received in an axial hole extending through the die assembly. Through rotation of the die assembly, punched core pieces are mounted on the mounting table while being rotatively offset. A drive mechanism is employed to rotate the mounting table integrally with the die assembly about the axis of the die assembly.

Abstract: A core of a rotating electrical machine is formed by laminating core plates, which are each formed by a plurality of core pieces. According to the method for manufacturing the core, a belt-like workpiece is first conveyed intermittently in its longitudinal direction. Then, while the workpiece is in a stopped state, side edges of a core piece are punched out. At a downstream position in the conveying direction of the workpiece, the remaining edges of the core piece are cut, so that the core piece is punched out. The punched out core pieces are lined up on a support. The core plate is thus formed, and the core pieces are laminated.

Abstract: The liquid container includes a liquid containing body having a flexible bag-shaped liquid containing section configured to contain liquid and a supply member that is connected to the liquid containing section and has a supply port configured to supply the liquid from the liquid containing section to an outside, and a case member configured to contain the liquid containing body. The case member has a first surface in which an opening section is formed to expose the supply port, and a second surface opposed to the first surface. The case member further has opposing sections that are opposed through the liquid containing section and are configured to contact with the liquid containing section in a position of a +Y-direction, which is a direction from the first surface to the second surface, than a joint section between the liquid containing section and the supply member.

Abstract: A rotary lamination apparatus includes a die, a punch, a rotation drive source, a mounting table, at least one proximity sensor, and a determining device. The punch punches core pieces from a thin plate material. The rotation drive source drives and rotates the die about the central axis of the die. The mounting table is arranged in the inner space formed by the die. The core pieces are rotated and laminated on the mounting table. The proximity sensor detects whether the die is in the proximity of a predetermined position in a non-contact manner after the die has stopped rotating. The determining device determines whether the die is stopped at the predetermined position based on a detection result from the proximity sensor.

Abstract: A rolling-element bearing in which a rolling element is retained in each of retaining openings formed in a retainer and method for manufacturing the bearing are provided. Each retaining opening is defined by a pair of inner side faces facing each other, and a pair of inner end faces facing each other. In the manufacturing method, with a support die being brought into contact with one of the inner side faces and the inner end faces of one of the retaining openings, the outer and inner circumferential surfaces of the retainer are pressed by an outer punch and an inner punch. Accordingly, on at least one of the inner side faces and the inner end faces, a first retaining piece and a second retaining piece for preventing the rolling element from falling off are formed on the outer circumferential surface and the inner circumferential surface of the retainer, respectively.
