Description

BRIEF DESCRIPTION OF THE DRAWINGS

[0013] The invention is subsequently is described based on an embodiment with reference to drawing figures, wherein:

[0014] FIG. 1 illustrates a tube profile cutting machine according to the invention cutting a contour at a tube;

[0015] FIG. 2A illustrates the tube profile cutting machine according to the invention cutting a contour at a cambered floor;

[0016] FIG. 2B illustrates details of the preceding FIGs;

[0017] FIG. 2C illustrates details of FIG. 1 and FIG. 2A.

DETAILED DESCRIPTION OF THE INVENTION

[0018] The illustrated tube profile cutting machine 1 according to the invention includes a cutting device 2 and a clamping device 3. The clamping device 3 is fixated in place on a base that is not illustrated and includes a three jaw clamping chuck 4.

[0019] The clamping chuck 4 has an interior diameter of 1200 mm and an exterior diameter of 2500 mm and thus facilitates clamping tubes centered relative to a longitudinal axis 5 wherein an exterior diameter of the tubes is smaller than 1200 mm or an exterior diameter of the tubes is greater than 2500 mm.

[0020] The clamping chuck 4 is pivotable by a pivoting device 6 about a horizontally extending pivot axis 7 of a pivot joint 8 by 90 and thus rotatable about the longitudinal axis 5 for machining tubes and rotatable about the vertically extending symmetry axis 9 for machining cambered floors.

[0021] The cutting device 2 is movable by the chassis 10 parallel to the longitudinal axis 5 and movable by a vertical drive 11 along a vertical axis 12 and rotatable by 360 about the vertical axis 12 by a rotary drive 13.

[0022] A cutting head 14 (a blow torch) arranged at the cutting device 2 is pivotable by a pivot drive 15 about a horizontal pivot axis 16 by 70 from vertical, From the cutting head 14 a non illustrated burning beam is orientable in a beam direction 17 towards the tube or the cambered floor. The cutting head 14 is feedable by a feed drive 18 in the beam direction 17.

[0023] The controlled axes are motion coordinated with each other during the cutting process and facilitate exact positioning of the work piece relative to the cutting head 14. All controlled axes are configured with non illustrated AC-servo drives and controllers.

[0024] A laser sensor that is not illustrated continuously controls a distance of the cutting head 14 from a surface of the work piece.
