Equipment for manufacturing a separator plate for a fuel cell, according to an embodiment of the present disclosure, includes: a first uncoiler uncoiling a first metal strip; a second uncoiler uncoiling a second metal strip; a press receiving the first metal strip and the second metal strip to respectively form patterns thereon; a welding machine overlapping and integrally bonding the first metal strip and the second metal strip, transferred from the press, by a welding process; and a cutter cutting a bonded body of the first metal strip and the second metal strip, transferred from the welding machine, wherein the press, the welding machine, and the cutter are sequentially arranged, and the first metal strip and the second metal strip are passed through the press, the welding machine, and the cutter, while connected to each other, to be processed.

A profiled nut (1) of a screw drive includes a sleeve (3) produced from sheet steel, has a non-cuttingly formed rolling profile (4) on the inner circumference for rolling contact with rolling bodies and is hardened in a heat treatment method at least in the region of the rolling profile (4). An inner lateral surface of the sleeve (3) having the rolling profile (4) is hardened and has a higher Rockwell hardness. An outer lateral surface of the sleeve (3) is designed such that it can be welded and has a lower Rockwell hardness.

An object of the present disclosure is to provide an elbow-shaped duct manufacturing apparatus in which the height of a forming section is easily adjusted as a duct vane forming part has an up and down detachable structure.

The disclosure relates to a method for producing a overlapping connection, in which at least two overlapping components are connected to one another via a folded flange, with a first edge of a first component being folded over a second edge of a second component to form the folded flange, along with a body component that includes such an overlapping connection for a vehicle and a stamping tool for such a body component. According to the disclosure at least one connection region is formed on the folded flange, in which the stamping tool stamps the first component through the second component at least one stamping point, with displaced material of the first component passing into the second component and producing a positive connection.

A method of forming a vehicle panel includes deforming a sheet metal workpiece between stamping tools to form a first and second edges that converge at a corner of the workpiece's main surface. The first edge is defined by a junction of the main surface and a first flange. The second edge is defined the main surface and a second flange. Forming the first and second edges includes deforming the workpiece so that the second flange has a first region bent to a first angle relative to the main surface and an unwinding region bent to an angle that unwinds from the first region as the second flange approaches the corner. The method includes deforming the workpiece between a second set of stamping tools that deform the first flange and the unwinding region of the second flange until the first and second flanges are bent greater than 90°.

A duct making apparatus includes a first station configured to accept a formable sheet material and a second station configured to receive the formable sheet material from the first station. The first station includes a mechanism for forming one of a male lock bend and a female lock seam in a leading edge of the formable sheet material. The second station includes a retractable conveyor. Movement of the sheet material from the first station to the second station defines an axis of travel of the sheet material. The retractable conveyor is selectively movable from a first position in which the retractable conveyor is in close association with the first station, and a second position in which the retractable conveyor is spaced from the first station.

A gas-charging and flanging machine (10) includes a sealed chamber (13a). The gas-charging and flanging machine is used for carrying out, inside the sealed chamber, charging of a gas into a workpiece (20) and flanging of the workpiece (20) by spinning and pressing. The gas-charging and flanging machine charges a gas into a workpiece and flanges the workpiece on the same machine such that production efficiency can be improved.

A vertical Pittsburgh Seam closing apparatus having a base supporting surface, a track mechanism for moving a carriage assembly which holds seam forming members used to close a Pittsburgh Seam, a pair of upper and lower guide members for guiding the duct section into a proper vertical position, and upper and lower clamping members positioned inside the duct section and adjacent the inside portion of the Pittsburgh Seam to be closed, the upper guide members and clamping member being selectively movable and adjustable for accommodating different duct section lengths. In one embodiment, the seam forming assembly includes three roller members mounted in vertical arrangement to each other, one roller member being V-shaped in configuration and the other two roller members being substantially cylindrical in shape. The V-shaped roller member may also include one or more projecting members for forming dimples in the closing process to prevent shifting and/or slipping of the closed seam.

A method of manufacturing a multi-sided or otherwise relatively three-dimensional formed structure for, e.g., an aerospace vehicle. A relatively planar base structure is constructed using a first construction technique. Features (e.g., ribs) are incorporated into the base structure using a second construction technique (e.g., additive or subtractive manufacturing) to create an intermediate structure. The intermediate structure is folded along fold-lines or otherwise physically formed to create the formed structure, such that some of the features are located within an internal space defined by the formed structure. Joints between the sides of the formed structure are welded, fastened, or otherwise secured. Separately constructed additional elements (e.g., bulkheads) may be incorporated into the structure. A closeout element may be added to the formed structure to further define and close the internal space. Throughout the process, the structures, features, and elements may be refined to desired tolerances.
