Definitions

  • the present invention relates to a method and a device for bending tubular or rod-shaped material according to the preamble of claim 1.
  • curved tubes are used for example in solar collectors or heat exchangers in the form of heat exchanger coils.
  • meandering pipes through which a heat transfer medium is pumped.
  • bending machines are used, which pull the pipe material from a reel over a guideline. Subsequently, the tube is pushed along a bending head and finally carried out at the desired location, the bend. This gradually creates a meandering pipe structure.
  • the device for bending tubular or rod-shaped material has a bending unit with a plurality of guided on guide axes bending heads, which are coupled together such that a plurality of bends of the tubular or rod-shaped material in a bending operation can be performed.
  • the bending device according to the invention makes it possible that in a bending operation not only one bend of the material to be bent is generated in each case, but a plurality of bends can be executed simultaneously or in quick succession.
  • the bending heads preferably consist of a bending contour and a bending roller.
  • the bending contours are arranged so perpendicular to the bending direction rotatable on the device that they can be created between a tubular or rod-shaped material partially encompassing position and the tubular or rod-shaped material releasing position. This makes it possible that the material to be bent after the bending process can be released in a simple manner.
  • the bending rollers are rotatably arranged on coupling rods, wherein the coupling rods are formed adjustable in length in a further preferred embodiment variant.
  • adjustable coupling rods it is possible to bend the material to be bent, for example, to meanders of different lengths.
  • the invention further relates to a method for producing a meandering pipeline having a plurality of bends, wherein according to the invention a plurality of bends are produced simultaneously in one step.
  • a plurality of bends are produced simultaneously in one step.
  • four bends are produced simultaneously. This allows several turns produced at the same time and in addition to a faster production time and a more exact dimensional compliance can be ensured.
  • the generated windings are then advanced by an amount corresponding to the length of the generated winding body and the next windings are generated in one step.
  • top, bottom, left, right, front, back, etc. refer exclusively to the exemplary representation and position of the device and other parts selected in the figures. These terms are not intended to be limiting, that is to say, by different working positions or the mirror-symmetrical design or the like, these references may change.
  • FIG. 1 is a first embodiment of a device according to the invention shown for bending tubular or rod-shaped material 20.
  • This has a straightening section 18 in which the starting material, which is unwound, for example, from a coil, not shown, is bent straight.
  • This straightening section 18 consists, for example, of blocks known from the prior art with respective straightening rollers.
  • a conveyor unit 3 for supplying the tubular or rod-shaped material 20 is provided in a bending unit 1, wherein the conveyor unit 3 drivable by a drive rollers 2, between which the tubular or rod-shaped material 20 is clamped and by the rotation of the Rollers is advanced.
  • the material to be bent 20 is pushed by the conveyor unit 3 in the bending unit 1.
  • the bending unit 1 is located in FIG. 1 in an initial situation before the execution of a bending operation, that is in an extended position.
  • FIG. 2 a situation is shown after a completed bending operation.
  • the bending unit 1 has a plurality of bending heads 21, 22, 23, 24, which, as in the FIGS. 1 to 3 shown, each consisting of a bending contour 8, 9, 10, 11 and a bending roller 14, 15, 16, 17.
  • the bending heads 21, 22, 23, 24 are arranged on respective guide shafts 4, 5, 6.
  • one of the guide shafts 5 is fixed to a frame of the bending device, while the other two guide shafts 4 and 6 are perpendicular to the longitudinal extent of the guide shafts 4, 5, 6 and parallel to the insertion direction of the material to be bent 20 slidably.
  • a first bending head 21 on the fixed guide axis 5 a second bending head 24 on a first linearly displaceable guide axis 6 and a third and fourth bending head 22, 23 on a perpendicular to the direction of displacement of the first linearly displaceable guide shaft 6 slidable slide. 7 arranged, wherein the carriage 7 is arranged on the second parallel to the first guide axis 6 linearly displaceable guide shaft 4.
  • the guide shafts 4, 5, 6 connected via coupling rods 12, 13.
  • the displaceable guide shafts 4, 6 can be driven by a drive 28, 29 mounted on the stationary guide shaft 5 or by drives 25, 26 arranged on the individual guide shafts 4, 6.
  • the guide axes are provided with individual or coupled drives 30, 31, 32, 33, 34, 35 and can be driven by these individually or in a coupled manner.
  • the bending contours 8, 9, 10, 11 are preferably formed so that they have a bending section with a circumferential groove 19 which partially surrounds the tubular or rod-shaped material 20 to be bent during a bending operation.
  • the bending contours 8, 9, 10, 11 are arranged rotatable perpendicular to the bending direction on the guide shafts 4, 5, 6. This ensures that the material to be bent 20 after the bending process by turning the bending contour in a certain angular position, in which the bending contour no longer encloses the material, released and the finished bent material 20 can be advanced for a next bending process.
  • the bending contours 8, 9, 10, 11 are each bending rolls 14, 15, 16, 17 opposite, which are rotatably arranged on the coupling rods 12, 13.
  • the bending rollers 14, 15, 16, 17 are positioned on the coupling rods 12, 13 such that they are guided in the process of the carriage 7 transversely to the longitudinal direction of the unbent bending material 20 to the bending contours 8, 9, 10, 11 and thereby bend the material to be bent along the bending contours 8, 9, 10, 11.
  • the first bending head 21 are arranged on the fixed guide shaft 5
  • the bending heads 22 and 23 are arranged on the carriage 7 mounted on the movable guide shaft 4
  • the fourth bending head 24, consisting of the bending contour 11 and the bending roller 17th is arranged on the linearly displaceable guide shaft 6. If the carriage 7 and the guide shaft 4 is moved, the result is a movement of the bending heads 22 and 23 in a plane with the bending heads 21 and 24th
  • the coupling rods 12, 13 have in a first variant of the device a fixed length, which is adjustable at the beginning of production. This results in a geometric relationship of the distances of the guide axes to each other with the deflection of the carriage. 7
  • the length of the coupling rods 12, 13 is made variable, for example by a sliding element integrated into the coupling rods 12, 13.
  • the length of the coupling rods 12, 13 are changed during the bending process, so that the distances of the guide axes 4, 5, 6 in relation to the carriage movement of the carriage 7 can be controlled independently.
  • variations of the bending geometries, in particular meander geometries are made possible.
  • the material to be bent 20 has undergone four bends and thus in a single bending operation, the material to be bent 20, as shown here, is bent into a meander.
  • the device according to the invention may also have a plurality of juxtaposed bending units 1, 1 ', 1 ", 1"', 1 "". Each individual bending unit generates a meandering turn in one go, so that several turns can be produced at the same time with such a device, thereby significantly increasing the production speed.
  • a variant of the bending device shown a total of three bending contours 37, 38, 39 are provided, wherein one of the bending contours 38 is disposed on the fixed to the guide shaft 5, the second bending contour 39 on the opposite to the fixed guide axis 5 along guides 46, 47 and displaceable a drive 33 drivable guide shaft 44 and the third bending contour 37 arranged on a perpendicular to the direction of displacement along a guide 48, 49 linearly displaceable and driven by a drive 32 guide shaft 45 slidable carriage.
