In a method for producing a multilayered heat shield, which has a first metal layer and a second metal layer that has an insulating layer arranged between the metal layers, the metal layers are connected at the edge by a flanging. To produce the heat shield, the first metal layer, the insulating layer and the second metal layer are placed into a first pressing tool. This is effected in such a way that an edge portion of the first metal layer protrudes beyond an edge portion of the second metal layer. The insulating layer is set back from the edge portions of the first metal layer and of the second metal layer.

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.

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°.

Systems and methods produce or provide a folded connection, sealed by means of an adhesive composition, between a first sheetlike element and a second sheetlike element. The systems and methods bond a second flange of the second sheetlike element with at least one layer of an adhesive composition to a first flange of the first sheetlike element, in such a way that an end of the second flange of the second sheetlike element is indented by a distance relative to an end of the first flange of the first sheetlike element. The systems and methods bead the first flange of the first sheetlike element around the second flange of the second sheetlike element and, after the beading, an adhesive-composition part is placed around an edge of the first flange of the first sheetlike element and bonded to a second surface of the first flange of the first sheetlike element.
