  • Patent number: 9015916
    Abstract: A method for the pressing of a press fitting, with a tube inserted into the press fitting, by way of a pressing tool, wherein the press fitting has an encircling bead in which an O-sealing ring is placed, wherein the tube ends within the press fitting and a first pressing is carried out within the bead, wherein, furthermore, a further pressing is carried out on the tube-insert side of the press fitting at a distance from the bead, the further pressing leading to press fitting and tube obtaining a conicity which prevents them being pulled off and runs in the same direction. Furthermore, the invention relates to a pressing tool suitable for carrying out the method.

  • Patent number: 7814827
    Abstract: A locking bolt for mounting a tool in a hydraulic press, it being possible for the locking bolt to move in a bolt receptacle between a locking position and a release position, with a securing element, which is located in the bolt receptacle and secures the locking position by positive engagement in the locking bolt, the locking bolt also having a securing portion, and the locking bolt being secured against movement into the release position when the securing element is located in the securing portion. The locking bolt has a longitudinal groove, in that the securing portion is formed with a securing depth in any event corresponding to a groove depth of the longitudinal groove and in that the securing portion is formed such that it is adjacent to the longitudinal groove in the circumferential direction, with a direct transition from a groove base into the securing position.
