An automotive panel assembly according to an exemplary aspect of the present disclosure includes a first panel, a second panel, and a flange of the first panel folded over an edge region of the second panel to hem together the first and second panels. The flange of the first panel includes a textured geometry that interlocks with a textured geometry of the edge region.

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.

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.

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.

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.

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.

The end portion of a first member includes a plate part and a groove. The end portion of a second member includes an edge and two side surfaces. The groove extends around the edge of the second member and the two side surfaces. The groove includes a side surface including an engaging portion. One of the side surfaces of the end portion of the second member includes an engaged portion. A method for manufacturing a swaged structure includes preparing the first member including the plate part and the groove having a wide opening. The method further includes inserting the end portion of the second member into the groove after preparing the first member. The method further includes pressing the plate part in a direction narrowing the opening of the groove to bring the engaging portion into contact with the engaged portion after inserting the second member.

The flange of the first panel includes a textured geometry that interlocks with a textured geometry of the edge region.

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.
