  • Patent number: 9770780
    Abstract: A pulsed joining tool includes a tool body that defines a cavity that receives an inner tubular member and an outer tubular member and a pulse joining cartridge. The tubular members are nested together with the cartridge being disposed around the outer tubular member. The cartridge includes a conductor, such as a wire or foil, that extends around the outer tubular member and is insulated to separate a supply segment from a return segment. A source of stored electrical energy is discharged through the conductor to join the tubular members with an electromagnetic force pulse.

  • Patent number: 9527125
    Abstract: A draw die set defines a die cavity. A die entry area is provided at the location where a blank is drawn into the die cavity. A plurality of rolling elements such as cylindrical rollers or spherical balls are retained in pockets formed at the die entry area. A punch may be provided with rolling elements that engage a blank on the opposite side from the rollers in the die entry area. The rollers in the die entry area and on the punch may be arranged in rows that form a tangent surface that engages the sheet metal blank as it is drawn into the die cavity.

  • Patent number: 9522419
    Abstract: A method of forming a part that has areas of high strain and predicted areas of low strain from a blank and method of designing a die for forming such a part. Predicted areas of low strain are identified that are adjacent to predicted areas of high strain. A pre-forming die is designed to form the blank to provide a donor pocket in an intermediate part in a predicted low strain area that is adjacent to the predicted high strain area. The donor pocket of the intermediate part is drawn into the predicted high strain area while forming the intermediate part into the part.

  • Patent number: 9500304
    Abstract: A method of joining parts with an electromagnetic joining process and an assembly made according to the process. Seals are assembled to a first part and a second part is assembled over the first part and the seals. A lubricant is applied to the first part between the seals to preoccupy or partially fill the area within the joint to prevent moisture from penetrating into the joint and causing corrosion. A portion of the second part is deformed into recesses formed in the first part to join the first and second parts.

  • Patent number: 9375775
    Abstract: A hydromechanical forming tool is disclosed that may include electro-hydraulic forming chambers in which a stored charge circuit may be discharged through electrodes to improve the level of detail that may be formed in a blank. The hydromechanical forming tool may include a liquid chamber at the entrance to the draw chamber to reduce friction, as the blank is drawn into the draw chamber. The draw chamber may have a movable bottom wall that is moved in tandem with the punch to reduce the amount of liquid in the draw chamber and reduce the need to pump liquid into and out of the draw chamber during a hydromechanical forming tool cycle.

  • Patent number: 9327331
    Abstract: A tool and method of hemming a panel wherein the tool engages a flange to apply a compressive force with a stop initially preventing a distal end of the flange from moving inwardly. The hemming tool bends the intermediate portion of the flange between the flange bend and the distal end toward the panel. The stop is withdrawn to allow the flange to be progressively formed toward the panel until the distal end is aligned with the intermediate portion.

  • Patent number: 9296037
    Abstract: A method of riveting two metal parts through a hole with an electro-hydraulic riveting tool. The electro-hydraulic riveting tool includes a tube that is inserted in the hole and an electrode that is inserted within the tube. A liquid is contained within the tube and the electrode is immersed in the liquid. A stored charge is discharged through the electrode to create a shockwave within the fluid that forms the tube into a rivet structure and creates solid state weld between the rivet flanges and the parts that are joined.

  • Publication number: 20160008865
    Abstract: One or more electro-hydraulic forming tools are operated by a press and provide formed parts to a trimming operation. A locking mechanism holds the die against the chamber during the electro-hydraulic forming (EHF) discharge. The lock may be a pin or clamp. One method of manufacturing an article includes providing three EHF tools that feed a single trimming press on a line. An alternative embodiment discloses a single EHF tool that supplies parts on a production line to an electro-hydraulic (EH) trimming tool. An electro-hydraulic pulse generator may be used to provide a stored charge to the EHF tool and the EH trimming tool.

  • Patent number: 9044801
    Abstract: A method of manufacturing a drawn panel and a die set. The method includes clamping a blank between a binder and a die that defines a cavity. A first draw punch contacts the blank in advance of a second punch that subsequently engages the blank. A central area of the blank is drawn by the first draw punch that clamps a central area of the blank against a lower die. Side areas of the blank are drawn into the cavity by the side punches while the central punch clamps the blank again the lower die.
