Radial press for cylindrical workpieces

Claim 1

A radial press for workpieces with cylindrical outer surfaces, comprising: a plurality of pressing jaws arranged in a circle for radial movement toward the axis of a workpiece outer surface, each jaw having outer surfaces, composed of surface parts, whose generatrices extend at two different angles other than 90 degrees relative to the axis of a workpiece; a pressure ring having an inner surface composed of surface parts, the generatrices of which extend at two different angles other than 90 degrees relative to the axis, the inner surface of the pressure ring configured to be cooperative with the outer surfaces of the jaws; means for axially displacing the pressure ring to effect movement of the jaws; wherein both the pressure ring and the pressing jaws each have two surface parts having a wide setting angle and two surface parts having a narrow setting angle, the surface parts having a wide setting angle being disposed, firstly, at end faces and, secondly, between the surface parts having the narrow setting angle, wherein the generatrices are of substantially equal length and the surface parts which cooperate with each other are substantially complementary to each other, whereby when the pressing jaws are closed, surface parts having a wide setting angle are deployed first, and then the surface parts having a narrow setting angle are deployed.
