  • Disk gang bolt tensioning structure
    Patent number: 8672046
    Abstract: An agricultural disk gang includes an elongated disk gang bolt having a threaded end with an externally threaded surface. A plurality of cultivating disks are supported on the disk gang bolt. A nut is threadably engaged with the externally threaded surface. The nut has a first side facing the disks and a second side facing away from the disks. The nut is disposed to axially compress the disks together on the disk gang bolt when tightened. A tensioning structure is mounted on the disk gang bolt outside of the nut. The tensioning structure has a plurality of threaded through holes. A plurality of threaded fasteners are threadably engaged with the threaded through holes and are disposed to axially compress the disks when the plurality of threaded fasteners are tightened, thereby permitting the nut to be further tightened.

  • Method for the attachment of a functional element
    Patent number: 7581300
    Abstract: A method for placing a functional element, especially a fastening element, in an especially liquid-tight and/or gastight manner, on a metal part. In this method a functional element provided with a hollow head segment is pressed against the metal part (212) witch is supported by a die (214). The metal material is deformed into an undercut (324) by deforming the head segment when simultaneous deformation of the hollow head segment occurs and the metal part is shaped in a forming area defined by parts (216) of the die (214). The parts (216) are kept in a stationary position during the forming process but are partially removed from the die to enable the functional element which is placed on the metal part (212) to be extracted. The invention also relates to a die, a functional element, an assembly element and a die arrangement.
