摘要： To provide a method for manufacturing an outer panel in which takt time is shortened and of high designability. A method for manufacturing an outer panel performing a hemming process according to the present disclosure includes; performing a laser light irradiation process on an inner side of a steel sheet that serves as an outer panel to bend the steel sheet at a first angle, the laser light being irradiated along a ridgeline of a center part of a bend radius of the steel sheet, and performing the hemming process on the steel sheet at a timing that is after the laser irradiation process to bend the steel sheet at a second angle smaller than the first angle.

摘要： Presented are metalworking systems for forming metallic workpieces, methods for making/operating such metalworking systems, and battery module cell tabs bent by a multistage cluster-and-bend press. A metalworking system includes a grouping tool and a contouring tool that both align adjacent a workpiece support structure, such as a base plate of a battery module housing buttressing a stack of battery pouch cells. The grouping tool, which may include a first reciprocating plunger or plunger head, presses together a stack of metallic workpieces to thereby form a workpiece set having a first bend profile and a first length. The contouring tool, which may include a second reciprocating plunger or a pair of plunger fingers mounted on the plunger head, is attached to the grouping tool and bends the workpiece set to a second bend profile, distinct from the first bend profile, and a second set length, shorter than the first set length.

摘要： A roller hemming device includes a backing metal, a guide roller, a bending roller, a pressing unit, and a swinging unit. The backing metal includes an abutment surface and a guide surface. The abutment surface is brought into abutment against a first panel member. The guide roller is moved in an extending direction of the guide surface with abutting against the guide surface. With being moved synchronously with the guide roller, the bending roller presses a bent peripheral edge portion of the first panel member via the backing metal such that the bent peripheral edge portion of the first panel member is pinched between the bending roller and the guide roller, and folds the bent peripheral edge portion of the first panel member back to a periphery edge portion of a second panel member. The pressing unit presses the bending roller toward the backing metal.

摘要： A hand-held drive cleat tool for the forming of sheet material such as drive cleats. The tool has a first handle; a second handle pivotably coupled to the first handle at a handle pivot; the handle pivot having a handle pivot axis; an inner jaw coupled to the first handle; the inner jaw having an inner jaw cutting edge substantially triangular in cross section in an inner jaw plane parallel to the handle pivot axis; an outer jaw coupled to the second handle, the outer jaw having an insert surface beveled in a cutting plane orthogonal to the inner jaw plane; the outer jaw having a surface defining an outer jaw cutting edge adjacent which the inner jaw cutting edge passes; and wherein rotation of the second handle relative to the first handle rotates the inner jaw relative to the outer jaw.

摘要： The present invention provides a method for producing a full engagement Pittsburgh male lock using specific cutting assemblies and protocols that reduce the amount of metal that is removed from the male portion of the corner notches in the duct. Forming of the male portion of the lock is done after the connecting flange forming has been completed as opposed to before the connecting flange forming has been completed.

摘要： A manufacturing assembly for manufacturing a metal part comprises a flattening module having a trolley and at least one pressing roller. The flattening module is movable along a hemming of the metal part. The flattening module comprises at least one pressing actuator that is arranged to move the at least one pressing roller in a determined pressing direction relative to the trolley and to place the pressure roller bearing against the free surface such that the at least one pressing roller exerts pressure on the free surface in said determined pressing direction. The pressure increases auto-adaptively with an altitude of the free surface in a direction opposite the determined pressing direction.

摘要： Methods produce a folded connection, sealed by means of an adhesive composition and by means of first and second sheetlike elements, wherein a flange of the first sheetlike element, having a first surface (11) and a second surface (12), is taken back over a flange of the second sheetlike element. The methods apply at least one layer of an adhesive composition to the flange of the first sheetlike element, bead the flange of the first sheetlike element around the flange of the second sheetlike element, and apply the adhesive composition to both the first and second surfaces of the flange of the first sheetlike element.
