Compression jaw assembly unit

A compression jaw assembly unit for a compressing device for compressing tubular metal parts, the compression jaw assembly unit comprising:

• a compression jaw carrier;
• and
• a compression jaw provided at the compression jaw carrier, the compression jaw having a compressing surface oriented essentially facing away from the compression jaw carrier that is curved transversely to a compression jaw longitudinal direction in a compression jaw transverse direction, the compression jaw comprising a fixed compression jaw segment, which is fixed to the compression jaw carrier and provides a fixed compressing surface segment, and at least one movable compression jaw segment providing a moveable compressing surface segment, wherein the at least one movable compressing surface segment is moveable in a direction of movement in relation to the fixed compressing surface segment against a prestressing action of a prestressing device, wherein:
• a compression jaw segment guide formation is associated with the at least one movable compression jaw segment;
• and
• the compression jaw segment guide formation guides the at least one movable compression jaw segment for movement in relation to the fixed compression jaw segment in the direction of movement, wherein the guide formation comprises:
• at least one guide element carried on the fixed compression jaw segment and extending essentially in the direction of movement and a guide opening movably receiving the at least one guide element in the direction of movement, in the at least one movable compression jaw segment associated with the guide element;
• or
• a support surface, which supports the at least one movable compression jaw segment on a rear side facing away from the compressing surface;
• or
• at least one guide element carried on the fixed compression jaw segment and extending essentially in the direction of movement and a guide opening movably receiving the at least one guide element in the direction of movement, in the at least one movable compression jaw segment associated with the at least one guide element and a support surface, which supports the at least one movable compression jaw segment on a rear side facing away from the compressing surface;
• wherein the guide formation comprises at least two guide elements of the at least one guide element;
• wherein:
• the at least two guide elements are arranged at spaced locations from one another in the compression jaw longitudinal direction;
• or
• the at least two guide elements are arranged at spaced locations from one another in a compression jaw radial direction at right angles to the compression jaw transverse direction and to the compression jaw longitudinal direction;
• or
• the at least two guide elements are arranged at spaced locations from one another in the compression jaw longitudinal direction and in the compression jaw radial direction.
