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.

摘要： A system for automatically forming sheet metal tubes from blanks cut to size. The system having a mechanism for positioning a blank for processing. A lifting arrangement having a wrap strap and pressure pad to raise the blank to a forming station having a mandrel is positioned so that the wrap strap extends on either side of said mandrel and underneath the blank before a side wiper on each side of said mandrel forces the overlap of opposite edges of the blank along a length of the mandrel. The mandrel includes a clinching die bar along its length. A sealing mechanism with a vertically movable row of clinching prongs is lowered to attach the overlapping edges of the blank by clinching at multiple positions to form a tube around the mandrel before being removed by a gag bar and a stripper plate.

摘要： 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.

摘要： A roller hemming apparatus includes a receiving body including a receiving member coming into contact with an edge of a panel workpiece, a roller body including a roller member bending a panel flange at the edge of the workpiece toward the receiving member, and a movement unit moving the roller body along the edge and tilts up or down the roller body toward the flange. The roller member hems the flange through the tilting-up operation of the roller body. One of the receiving and roller bodies includes a guide recess and the other includes a convex curved surface coming into sliding contact with the recess. The recess and the surface have a same curvature. The roller body is tilted up to bend the flange or tilted down to move away from the flange around a center of curvature common to the surface and the recess that come into sliding contact.

摘要： 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.

摘要： 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.
