Abstract (en)
A device for widening an end portion of a pipe part comprises a clamping member for clamping a pipe part to be widened on the outside, and a mandrel, directed towards the clamping member, for widening an end portion of a clamped pipe part. The clamping member and the mandrel are displaceable with respect to each other substantially in the axial direction of the mandrel. The device furthermore comprises a clamp-actuating mechanism for actuating the clamping member and a displacement mechanism for displacing the clamping member and the mandrel with respect to one another, which mechanisms are combined to form a single combined mechanism, and only one actuating member for actuating the combined mechanism. The combined mechanism is designed in such a manner that, when it is actuated in order to widen an end portion of a pipe part, the clamping member comes into action first, and then the mandrel and the clamping member move towards one another. <IMAGE>
