Definitions

  • the present invention relates to a method for producing annular or tubular parts according to the preamble of claim 1 , particularly a method for cutting, rolling, and welding thin steel strip from a coil, and use of the method.
  • patent document DE 10 2008 027 807 B4 a method for producing steel pipes is described, wherein a metal sheet or coil is formed into a tubular body in a bending operation, provided with a longitudinal seam in a subsequent welding operation, and then subjected to a stress-relief treatment.
  • This method contains complex forming tools having a control device and contains an additional stress-relief treatment for reducing the stresses mechanically produced by the forming of the metal-sheet material.
  • Such a complex method is sensible for thick-walled tubes but is less suitable for thin-walled tubes according to the present invention.
  • the invention presented here describes a method that allows, in a continuous processing process, thin-walled, sheet-shaped starting material to be cut to the desired dimensions in a first sub-process, then to be rolled in a second sub-process, and finally to be provided with a welded longitudinal seam in a third sub-process by means of the same equipment—a combined machine.
  • this innovative method results in a favorable cost-benefit ratio for such final products which, on the basis of the tolerances, do not demand very high requirements, for example for drums of washing machines or of dishwashers.
  • FIG. 1 shows a schematic illustration of the production of annular parts according to the prior art.
  • FIG. 2 shows a schematic illustration of the production of annular parts according to the invention.
  • FIG. 3 shows a first cross-section of a combined machine according to the invention for producing annular parts.
  • FIG. 4 shows a second cross-section of a combined machine according to the invention for producing annular parts.
  • FIG. 5 shows a longitudinal section of a combined machine according to the invention for producing annular parts.
  • FIG. 6 shows a schematic illustration of a coil having the coil starting piece and the coil end piece.
  • FIG. 7 shows an annular workpiece produced by means of a combined machine according to the invention.
  • FIG. 1 shows the production of annular parts according to the prior art in a schematic illustration.
  • Thin metal sheet is fed in the form of a coil 7 from a decoiler 1 to the cutting machine 2 , where the metal sheet 10 is cut to the required starting dimension.
  • a mechanical and/or thermal rolling process is applied to the metal sheet 10 in one or more steps in a rolling machine 3 so that an annular open workpiece 34 having two longitudinal edges 29 a, 29 b is obtained, which longitudinal edges are then welded together by means of a weld seam 36 in a welding machine 4 , whereby an annular part 35 is obtained, which is optionally processed further in an additional processing step by means of an expanding machine 5 .
  • FIG. 2 shows, again in a schematic illustration, the inventive production of annular parts.
  • Thin metal sheet having a thickness in the range of 0.4 mm to 1 mm is continuously fed in the form of a coil 7 from a decoiler 1 to the combined machine 9 as a starting material, wherein the workpiece, in one and the same combined machine 9 , is fed by means of a roller mechanism, clamped, conveyed, cut to the required starting dimension, formed into an annular or cylindrical part on a rotating rolling machine, and welded and thus provided with a longitudinal seam 36 .
  • annular part 35 is automatically or manually removed from the combined machine 9 by means of a mechanism.
  • further processing can optionally occur in an expanding machine 5 in an additional work step.
  • FIG. 3 shows a cross-section of the combined machine 9 according to the invention for producing annular parts 35 , wherein the workpiece 16 is automatically fed in a conveying direction F of the combined machine 9 and is conveyed by means of the guiding rollers 19 a and the
  • FIG. 4 shows, in a further cross-section, a combined machine 9 according to the invention, wherein the workpiece 16 has been conveyed further by a half rotation in the
  • FIG. 5 shows the carrier 17 of the combined machine according to the invention, which carrier has an integrated cutting and welding device, in a longitudinal section, wherein the source 23 , preferably a laser source, is switchable, so that the source is mechanically and electrically connected either to the cutting head 24 , which can be moved in a
  • FIG. 6 shows, in a schematic illustration, a coil 7 , from which the coil starting piece 27 , which has a non-straight edge 30 , was cut off in a first processing step and from which a first good piece 31 having the straight welding edges 29 a, 29 b was cut off in a second process step. Furthermore, the coil end piece 28 having the non-straight edge 30 , and the last good piece 32 of the coil 7 and the next to last good piece 33 each having the two straight welding edges 29 a, 29 b , are illustrated.
  • FIG. 7 shows a slightly elliptical workpiece 34 produced in the combined machine 9 by means of the innovative method, after the cutting and rolling but before the welding, and an annular part 35 after the cutting, rolling, and welding, to which the longitudinally welded weld seam 36 has been applied.
