Abstract
An apparatus for the orbital cutting and calibration of tubes is provided. The apparatus has a rotor having a central hole through which a tube to be cut is movable along its longitudinal axis, the rotor being drivable to rotate about a first axis of rotation coinciding in use with the longitudinal axis of the tube that is supplied to the apparatus. The apparatus has a cutting device having a first support body mounted radially movable on the rotor and a cutting tool carried by the first support body, and a calibration device having a second support body mounted to be radially movable on the rotor and a calibration tool carried by the second support body.

An apparatus for orbital cutting and calibration of tubes, the apparatus comprising
- a rotor having a central hole through which a tube to be cut is movable along its longitudinal axis, the rotor being drivable to rotate about a first axis of rotation (x1) coinciding in use with the longitudinal axis of the tube that is supplied to the apparatus;
- a cutting device comprising a first support body mounted radially movable on the rotor, and a cutting tool carried by said first support body;
- and
- a calibration device comprising a second support body mounted radially movable on the rotor, and a calibration tool carried by said second support body,
- wherein the calibration tool is movable in a radial direction (outwards to produce an enlargement of an inner diameter of a piece of the tube,
- wherein said first support body and second support body are separate from one another and are mounted on the rotor so as to be movable along a same radial direction, and
- wherein the apparatus further comprises a single driving device paired both to said first support body and to said second support body to drive a movement of said first and second support bodies along said radial direction (y) in a symmetrical manner with respect to said first axis of rotation (x1).
A machine for straightening and cutting tubes from a coil, comprising an apparatus for orbital cutting and calibration of tubes, the apparatus comprising
- a rotor having a central hole through which a tube to be cut is movable along its longitudinal axis, the rotor being drivable to rotate about a first axis of rotation (x1) coinciding in use with the longitudinal axis of the tube that is supplied to the apparatus;
- a cutting device comprising a first support body mounted radially movable on the rotor, and a cutting tool carried by said first support body;
- and
- a calibration device comprising a second support body mounted radially movable on the rotor, and a calibration tool carried by said second support body,
- wherein the calibration tool is movable in a radial direction outwards to produce an enlargement of an inner diameter of a piece of the tube,
- wherein said first support body and second support body are separate from one another and are mounted on the rotor so as to be movable along a same radial direction, and
- wherein the apparatus further comprises a single driving device paired both to said first support body and to said second support body to drive a movement of said first and second support bodies along said radial direction (y) in a symmetrical manner with respect to said first axis of rotation (x1).
