Definitions

  • the invention is based on a method for producing a watertight radiator element from a flat tube with open ends, which ends are closed and welded, and a device for carrying out the method.
  • a radiator with flat elements running parallel to one another is described in GB-PS ' 2,094,966.
  • Support parts are inserted in the open ends of the flat elements, which form the end walls of the flat elements and are welded to the side walls of the flat elements.
  • FR-PS 2,475,708 describes a radiator with flat elements running parallel to one another, the end faces of which are closed in such a way that the edge parts of the opposite broad side faces of the flat tube are folded towards the center of the end faces and then welded to one another.
  • the closing is not accomplished by means of rollers.
  • the surface of the folded-over edge parts with the weld seam is not clean.
  • the invention specified in claim 1 was based on the object of proposing a method for producing a waterproof radiator element, in which the element receives a clean and symmetrically shaped surface.
  • the manufacturing costs of such an element should be kept low.
  • each flat tube end is carried out by rolling edge parts of the wide, opposite side walls of the flat tube by means of at least one flanging roller, which flanging roller in succession from the two sides over the edge parts in the direction of Is guided in the middle of the ends, after which the rolled edge parts are welded together in a semi or fully automatic TIG process.
  • the flanging roller advantageously carries out two taxiways, one of which is larger than the other, the taxiways partially overlapping.
  • the device according to the invention for carrying out the method is characterized in that a device for rolling the edge parts and a device connected to it for welding the rolled edge parts of the wide, opposite flat tube side walls are accommodated in a single unit.
  • a flat tube 1 with open ends 2, 3 used according to the Fig. 1.
  • the wall thickness of such a flat tube 1 is approximately 1.25 to 2.0 mm.
  • the flat tube has wide, opposite side walls 1a, 1b; it is cut to the desired length.
  • the flat tube 1 is closed at its ends 2, 3 and welded.
  • Each flat tube end 2, 3 is closed by rolling edge parts of the wide, opposite side walls 1a, 1b.
  • the rolling is carried out by means of two flanging rollers 4, 5, which flanging rollers are successively guided in opposite directions over the edge parts of the side walls 1a, 1b of the flat tube 1, namely from the two sides of the flat tube 1 towards the center of each end face 2, 3.
  • the first flanging roller 4 executes a larger rolling path x than the second flanging roller 5.
  • the flat tube 1 at the ends 2, 3 must be roll-deformed overlapping from both sides, ie that the roll paths x, y of the first and the second flanging rolls 4, 5 partially overlap.
  • TIG is derived from the English Tungsten Inert Gas (process).
  • the element closed by rolling is then suitable for pressing / welding processes in a device described in more detail.
  • any subsequent grinding is superfluous.
  • the finished radiator element has a clean shape and is waterproof.
  • FIG. 5 shows a device in which the above-mentioned method steps are carried out in a single work cycle.
  • a device 6 for rolling the edge parts of the wide, opposite side walls 1a, 1b of the flat tube 1 by means of two flanging rollers 4, 5 and a device 7 connected to it for welding the supplied rolled edge parts in a semi or fully automatic TIG process.
  • the device has a flat tube magazine 8, a hole device 9, brushes 10, a cross conveyor 11 and a magazine 12 of finished radiator elements.
  • the finished radiator elements are then fed from the magazine 12 to a further device, not shown, where they are welded with a collector pipe for supplying warm water and a collector pipe for discharging cooled water.
  • radiator element No additional parts, such as end caps, filler or support parts, are required to manufacture the radiator element.
  • a simple and symmetrically deformed element is obtained with simple means, with which any subsequent grinding is unnecessary.
