The present invention is an expansion tool device for pliers or machine for producing sockets at the ends of pipes made out of plastic or composite material, used in the field of plumbing. The device includes a cylindrically-shaped ferrule formed by the tightening of several sector-shaped chucks. The chucks are movable in the radial direction under the action of the insertion between them of a tapered needle movable in axial translation through the actuation of the pliers or machine. The chucks are allowed to pass from a tightened position to a separated position. In an integrated way or in a unit designed capable of being intercalated between the ferrule and the pliers or machine, there is an automatic driver for the ferrule, when the ferrule passes from the separated position to the tightened position, directly or indirectly, in axial swiveling according to a portion of a turn.

1. An interface element comprising: a fixed part adapted to be fixedly mounted to a pliers or machine for actuating an expansion tool; anda tapered needle operatively engaged with the fixed part for cyclic axial movement relative to the fixed part in response to operation of the pliers or machine for actuating an expansion tool,wherein the tapered needle is constructed and arranged to connect to a plurality of chucks of an expansion tool for producing a socket at an end of a polymeric or composite material pipe such that: (i) a portion of each complete cycle of said cyclic axial movement of the tapered needle causes the plurality of chucks to move radially outwardly, (ii) a portion of each complete cycle of said cyclic movement permits the plurality of chucks to move radially inwardly, (iii) and each complete cycle of said cyclic movement results in the plurality of chucks rotating for a portion of a turn relative to the fixed part; andwherein the interface element further comprises a rotatable member operatively engaged with the fixed part for rotation relative to the fixed part, wherein the rotatable member is constructed and arranged to operatively engage a plurality of chucks of an expansion tool for producing a socket at an end of a polymeric or composite material pipe such that the plurality of chucks rotate with the rotatable member relative to the fixed part, andthe rotatable member operatively engages the tapered needle such that: (i) each complete cycle of cyclic axial movement of the tapered needle results in the rotatable member rotating to an angular position that is different than an angular position of the rotatable member immediately prior to the complete cycle of said cyclic axial movement,(ii) the rotatable member rotates a portion of a turn while the needle is moving through a first portion of the cycle of said cyclic movement of the needle, and(iii) the rotatable member does not rotate while the needle is moving through a second portion of the cycle. 2. The interface element of claim 1, wherein the tapered needle is constructed and arranged to connect to a plurality of chucks of an expansion tool for producing a socket at an end of a polymeric or composite material pipe such that each complete cycle of said cyclic movement of the tapered needle causes each of the plurality of chucks to rotate to an angular position that was not occupied by any of the plurality of chucks immediately prior to the cycle of said cyclic movement. 3. The interface element of claim 1, wherein the tapered needle is constructed and arranged to connect to a plurality of chucks of an expansion tool for producing a socket at an end of a polymeric or composite material pipe such that a portion of each complete cycle of said cyclic movement of the tapered needle does not cause the plurality of chucks to rotate relative to the fixed part. 4. The interface element of claim 1, wherein: the cycle comprises an expansion stroke of the needle and a retraction stroke of the needle; andthe first portion of the cycle comprises the retraction stroke, such that the rotatable member rotates during at least a part of the retraction stroke. 5. The interface element of claim 1, wherein: the cycle comprises an expansion stroke of the needle and a retraction stroke of the needle; andthe second portion of the cycle comprises the expansion stroke, such that the rotatable member does not rotate during at least a part of the expansion stroke. 6. The interface element of claim 1, wherein: the cycle comprises an expansion stroke of the needle and a retraction stroke of the needle; andthe rotatable member operatively engages the tapered needle such that the rotatable member does not rotate during at least a part of the needle's expansion stroke. 7. The interface element of claim 1, in combination with a plurality of chucks of an expansion tool for producing a socket at an end of a polymeric or composite material pipe, wherein the plurality of chucks are constructed and arranged to operatively engage the fixed part so as to be movable in radial and rotational directions relative to the fixed part,wherein the plurality of chucks are constructed and arranged to operatively engage the rotatable part so as to cause the plurality of chucks to rotate with the rotatable member relative to the fixed part, andwherein the plurality of chucks are constructed and arrange to operatively engage the needle such that: (i) a portion of the cycle of cyclic axial movement of the tapered needle causes the plurality of chucks to move radially outwardly, and(ii) a portion of the cycle of cyclic axial movement of the tapered needle permits the plurality of chucks to move radially inwardly. 8. The interface element of claim 7, wherein the rotatable member comprises a surface feature that is constructed and arranged to engage a complimentary surface feature of the plurality of chucks so as to cause the plurality of chucks to rotate with the rotatable member relative to the fixed part. 9. The interface element of claim 8, wherein the rotatable member is rotatable relative to the needle. 10. The interface element of claim 7, wherein the plurality of chucks operatively engage the fixed part, the needle, and the rotatable member. 11. An expansion tool apparatus for producing a socket at an end of a pipe, the pipe being of a polymeric or composite material, the expansion tool apparatus comprising: a fixed part adapted to be fixedly mounted to a pliers or machine for actuating an expansion tool;a plurality of chucks operatively engaged with the fixed part and movable in radial and rotational directions relative to the fixed part;a tapered needle operatively engaged with the fixed part for cyclical axial movement relative to the fixed part in response to operation of the pliers or machine for actuating an expansion tool, wherein: (i) a portion of each cycle of said cyclical axial movement of the tapered needle causes the plurality of chucks to move radially outwardly,(ii) a portion of each cycle of said cyclical axial movement permits the plurality of chucks to move radially inwardly; anda rotatable member operatively engaging the fixed part for rotation relative to the fixed part, the rotatable member operatively engaging the plurality of chucks such that the plurality of chucks rotate with the rotatable member relative to the fixed part,wherein the rotatable member operatively engages the tapered needle such that: (i) each cycle of said cyclical axial movement of the tapered needle results in the rotatable member rotating to an angular position that is different than an angular position of the rotatable member immediately prior to the cycle of said cyclical axial movement of the tapered needle,(ii) the rotatable member rotates a portion of a turn while the needle is moving through a first portion of the cycle of the needle from, and(iii) the rotatable member does not rotate while the needle is moving through a second portion of the cycle. 12. The expansion tool apparatus of claim 11, wherein movement of the tapered needle through the cycle causes each of the plurality of chucks to rotate to an angular position that was not occupied by any of the plurality of chucks immediately prior to that cycle of movement of the needle. 13.
