Pressing jaw, method for producing a non-detachable pipe joint, fitting and system consisting of a pressing jaw and a fitting

The pressing jaw according to claim wherein the pushing unit has an upper pushing element and a lower pushing element.

A system, comprising:

• a pressing jaw for producing a non-detachable pipe joint, having an upper jaw half and a lower jaw half, at least one rotation axis which pivotally mounts at least one jaw half, a receiving region formed between the upper jaw half and the lower jaw half, and having a receiving region axis, whereby at least one jaw half is able to pivot between an open position and a closed position substantially transversely to the receiving region axis, wherein at least one pushing unit is provided, said pushing unit transforming a pivotal movement of the at least one jaw half performed substantially transversely to the receiving region axis into a displacement at least partly parallel to the receiving region axis;
• and
• a fitting having a base body and a press sleeve, wherein the receiving region of the pressing jaw is adapted to the fitting base body, and wherein the pushing unit of the pressing jaw is adapted to the press sleeve so that the press sleeve can be at least partly pushed onto the fitting base body by the pivotal movement.

A method for producing a non-detachable pipe joint using a pressing jaw for producing a non-detachable pipe joint, having an upper jaw half and a lower jaw half, at least one rotation axis which pivotally mounts at least one jaw half, a receiving region formed between the upper jaw half and the lower jaw half, and having a receiving region axis, whereby at least one jaw half is able to pivot between an open position and a closed position substantially transversely to the receiving region axis, wherein at least one pushing unit is provided, said pushing unit transforming a pivotal movement of the at least one jaw half performed substantially transversely to the receiving region axis into a displacement at least partly parallel to the receiving region axis,

• wherein a fitting base body located in the receiving region of the pressing jaw is fixed by actuating the pressing jaw, and wherein after the fitting base body has been fixed, a press sleeve is pushed onto the fitting base body by the pivotal movement.
