Patent ID: 7134303

Claim:
A device for socket-deforming an end of a tube, and for cutting the tube to a desired length, said cutting taking place at the end to be deformed, the device comprising: a deformation and cutting member to be inserted into the tube to be worked; said member having an inner diameter and comprising deforming means arranged to at least locally modify the inner diameter of the deformation and cutting member by varying its perimetral dimensions; said deforming means comprising a deforming tool and being arranged to cooperate with actuator means associated with a movable support; said actuator means extending along a longitudinal axis, and being able to translate along and rotate about said axis; cutting means for separating an end tube portion by acting from the tube interior, without chip removal, in order to obtain a deformed tube having the desired length; the deforming tool comprising parts hinged together and carrying projecting portions arranged to deform the tube from its interior; said parts having first ends cooperating with a presser member and second ends cooperating with the actuator means; said actuator means acting on the second ends in such a manner as to urge them apart in order to deform and cut the tube, said action opposing the action of the presser member which maintains said second ends close together; and said cutting means being carried by at least one of the parts of the deforming tool.
