Method for producing an overlapping connection, and body component for a vehicle
11759841 · 2023-09-19 · ·

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.

Fixation components for implantable medical devices

An example fixation component for an implantable medical device (IMD) includes a base and a plurality of tines configured be deployed with a target deployment stiffness to engage tissue a target implant site while maintaining a target deflection stiffness after deployment. The base defines a longitudinal axis of the fixation component and is fixedly attached near the distal end of the IMD. Each tine is spaced apart from one another around a perimeter of the distal end of the IMD and extend from the base. A shape of each tine is selected to control each of the target deployment stiffness and target deflection stiffness.

MULTISTAGE PLUNGER SYSTEMS AND METHODS FOR FORMING BATTERY CELL TABS
20220029141 · 2022-01-27 · ·

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.

One-piece sheet-metal structure formed with clench locked corners
11181279 · 2021-11-23 · ·

A one-piece sheet-metal structure includes a first wall, a second wall perpendicularly extending from the first wall, and a third wall perpendicularly extending from the first wall. The second wall is perpendicular to the first wall and the third wall. An end edge of the second wall is adjacent an end edge of the third wall to form a corner. The corner is provided with a clench lock so that the corner is weld-free. The clench lock includes bottom and top tabs. The bottom tab perpendicularly extends from the end edge of the second wall at a bottom tab bend and engages an inner side of the third wall. The top tab perpendicularly extends from an outer edge of the third wall at a top tab bend and bends around the bottom tab and engages an inner side of the bottom tab to clench the bottom tab at the corner.

METHOD FOR PRODUCING A MULTILAYERED HEAT SHIELD
20220001439 · 2022-01-06 ·

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.

Assembly for manufacturing a metal part and use of such an assembly

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.

SYSTEM AND METHOD FOR FORMING A FULL ENGAGEMENT MALE LOCK IN A DUCTLINE
20220003340 · 2022-01-06 · ·

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.
