Tube-profile cutting machine and method for cutting a contour

A method for cutting a profile,

• wherein at a tube profile cutting machine including
• a cutting device,
• a clamping device by which a tube is clampable centered about a horizontal longitudinal axis and rotatable about the horizontal longitudinal axis;
• a chassis by which the tube and/or the cutting device are movable parallel to the horizontal longitudinal axis and relative to one another,
• a vertical drive by which the cutting device is movable along a vertical axis,
• a rotary dove by which the cutting device is rotatable about the vertical axis;
• a cutting head arranged at the cutting device,
• a pivot drive by which the cutting head is pivotable about a horizontal pivot axis,
• a feed drive by which the cutting head is feedable in a beam direction;
• performs the steps:
• pivoting the clamping device by a pivot device by 90°;
• clamping a cambered floor for a container with a vertical axis of symmetry in a centered manner and rotating the cambered floor for the container about the axis of symmetry,
• moving the cutting head relative to the cambered floor by the chassis, the vertical drive, the rotary drive, the pivot drive and the feed drive, and
• cutting a countour at the cambered floor with a cutting beam that extits from the cutting head in the beam direction.

A tube profile cutting machine, comprising:

• a cutting device;
• a clamping device by which a tube is clampable centered about a horizontal longitudinal axis and rotatable about the horizontal longitudinal axis;
• a chassis by which the tube and the cutting device are movable parallel to the horizontal longitudinal axis and relative to one another;
• a vertical drive by which the cutting device is movable along a vertical axis;
• a rotary drive by which the cutting device is rotatable about the vertical axis
• a cutting head arranged at the cutting device;
• a pivot dove by which the cutting head is pivotable about a horizontal pivot axis;
• and
• a feed drive by which the cutting head is feedable in a beam direction,
• wherein the cutting head is movable relative to the tube by the chassis, the vertical drive, the rotary drive, the pivot drive and the feed drive so that a cutting beam extiting from the cutting head in the beam direction cuts a contour at the tube,
• characterized by a pivot device by which the clamping device pivotable by 90° so that a cambered floor for a container with a vertical axis of symmetry is clampable in a centered manner and rotatable about the vertical axis of symmetry.
