Definitions

  • the invention relates to a rolling device for rolling of connecting webs in profiles, with a passage opening for the profiles and on both sides of the passage opening opposite groups of rotatable coplanar rolling mill according to the preamble of claim 1. Furthermore, the invention relates to a method for rolling of connecting webs in profiles according to the preamble of claim 14.
  • FIG. 1 schematically shows such a procedure in which a profile 10 of a first profile part 11 and a second profile part 12 is formed.
  • the parts 11 and 12 may be aluminum profiles.
  • the profile 10 thus formed which can be several meters long, then passes through the rolling device, in which pairs of rollers 2 and 3 with disc-shaped rollers 4, 5 and 6, 7 on opposite sides of the profile act on the Nutenr selected and plastically deform, so that the webs are rolled into the grooves and thereby secured.
  • a plurality of roller pairs are provided in succession in the direction of passage, which effect the deformation correspondingly in several steps.
  • the rollers of each roller pair lie on a common shaft.
  • the waves are indicated only with their central longitudinal axes 8 and 9.
  • At least one of the rollers of each pair of rollers along the common shaft is adjustable in order to adjust the distance a between the rollers can.
  • Rollers 65 to 68 support the profile 10 as it passes through the mill.
  • Such rolling devices have proven successful, but the releasable attachment of the adjustable rolling disks on the shafts is structurally complex. Further, other than the illustrated profile form may require more than one pass through the rolling apparatus.
  • EP-A 82 468 is the rolling with inclined outer discs known. The adjustment of the distance of the rolling disks is done by replacing the whole tool carrier. In the method according to DE-B 27 55 669 is also used with inclined rolling discs and also only one-sided. Setting the distance is not addressed.
  • the invention has for its object to provide an improved rolling device. Furthermore, the curl method of the type mentioned is to be improved.
  • a rolling device of the type mentioned in which at least one of the groups two rolling disks of the group are rotatably supported by means of separate axes or shafts and an axis or shaft of each group is displaceable in its longitudinal direction to adjust the rolling disk spacing.
  • each rolling disk can be fixed permanently or non-detachably on its axle or shaft and the distance adjustment of the rolling disks takes place by the adjustment of the axles or shafts to each other.
  • This allows a simpler adjustment and a mechanically stable arrangement of the rolling disks and thus ensuring the parallelism of the rolling disks of the group.
  • the given by the separate axes or waves decoupling of the geometric axes of rotation of the two discs allows settings in which the axes or shafts of the two discs are not coaxial. This in turn allows the rolling of profiles in one pass even with profile shapes that previously required more than one pass through the rolling device.
  • each group of rolling disks has two disks and thus a pair of rollers. This allows profiles to be rolled up with two bars.
  • the groups could also include additional roll disks for other profile shapes with more lands.
  • both axes or shafts of a group are displaceable together in their longitudinal direction in order to adjust the rolling disks together.
  • This allows easy adaptation of the device to profile shapes, in which the webs are arranged offset to one another.
  • one rolling disk of each group is fixed to a driven shaft and another rolling disk of the group or pair is attached to a revolving axle.
  • rolling disks of a group can be drive-connected via an insertable driver element, in particular via a shaft connecting the shaft and axle, if the adjustment possibilities in the transverse direction to the axles or shafts are not required.
  • the other adjustment of the roller discs or their axes and waves have as the roller groups on the opposite side of the passage opening.
  • the force which the rolling disks exert on the profile can be measured separately for the rolling disks of a pair of rolling disks.
  • the groups of rolling disks are pivotable about the passage opening. This allows the adaptation of the rolling or rolling device to the feed position of the profiles, which are supplied due to their irregular shape in the resting on a transport element feed with non-vertical Nutenr skilledn. Instead of a rotation of the profiles, the groups of the rolling disks are thus preferably rotated, so that the rolling disk position adapts to the position of the Nutenr selected in space.
  • the invention is further based on the object to improve a method for rolling heat-insulating webs in metal profiles.
  • the axis of rotation of a rolling disk of a group, or a pair is adjusted in the longitudinal direction of the axis of rotation and in the transverse direction to the axis of rotation in the direction of action or against the direction of action of the rolling disk for adaptation to the profile.
  • FIG. 1 shows the already explained at the outset with reference to this figure procedure in the formation of thermally insulated metal profiles according to the prior art. Reference is made to the above explanations.
  • FIG. 2 shows in a likewise schematic representation of a rolling of the webs 13 and 14 in the parts 11 and 12 of the metal profile 10 with a device or with the method according to the invention.
  • Same reference numerals as in FIG. 1 again denote the same elements, which also applies to the other figures.
  • FIG. 2 and the following figures only one group 2 with rolling disks or pulleys 4,5 and another group 3 with the rolling disks 6 and 7 is shown. These two groups of rolling disks lie on both sides of the passage opening 25 (FIG. FIG. 7 ) of the device through which the profile 10 passes through the device.
  • the rolling device has a plurality of such groups on both sides of the passage opening or of the profile 10, which are arranged along the passage opening in the direction of passage, so that the profile is applied on both sides several times by rolling disks during the pass to achieve the rolling of the webs in several stages ,
  • the corresponding slightly converging setting of the opposing roll groups is known to the expert or the operator of rolling devices of this type and will not be further discussed and addressed, but also applies to the roll groups according to the present invention.
  • the further groups of rolling disks are behind the plane of the paper of the drawing and are therefore not apparent.
  • the drawings thus each show the inlet for the profile in the flow opening with the first group of rollers on both sides.
  • At least one of the pairs of rollers has separate axes or shafts. In this and the other figures, this is illustrated for both groups or for both pairs of rollers and it is preferred that all groups of the rolling device are designed in this way.
  • FIG. 2 shows now that the rolling disk 4, which is the upper roll of the roller pair or group 2, has its own axis or shaft 18, by means of which the rolling disk 4 is rotatably mounted (bearing 57).
  • the other rolling disk 5 of the pair of rollers 2 has its own axis or shaft 19, by means of which it is rotatably mounted (bearing 52). Due to the separate shafts / axes, the bearings of the two rolling disks 4 and 5 of the group 2 and the roller pair 2 are independent of each other.
  • FIG. 2 are the bearings for the shaft or axle 18 and 19 only indicated.
  • FIG. 5 is an example of the bearing of the shafts or axles explained in more detail.
  • one rolling disc 6 is rotatably supported by the shaft or shaft 20 in the rolling device (bearing 57) and the other rolling disc 7 is rotatably supported by its axis or shaft 21 ( Bearing 52).
  • This storage by means of separate axles or shafts of course allows the per se known setting of the distance a between the rolling disks.
  • either the axis or shaft 18 in the direction of its longitudinal central axis is adjustable in the rolling device, as indicated by the arrow A.
  • the storage unit 28 (FIG. FIG. 7 ) for the shaft or axle in the longitudinal direction adjustable.
  • the rolling disk 4 always remains firmly connected to its associated shaft or shaft 18, so that the setting of the distance a can be solved structurally easier than in the prior art, in which the rolling disk slidably disposed on its drive shaft and be detachable and fastened must to adjust the distance a.
  • the rolling disk 5 can be adjusted to adjust the distance a by adjusting its axis or shaft 19. The above also applies to the adjustment of the distance a in the pair of rolling disks 6, 7 or group 3.
  • FIG. 3 again the schematically simplified representation according to the FIG. 2 wherein a profile 10 is machined with a different shape.
  • the web 14 has a bend and the groove of the upper Profile part 12, which receives the web, is not vertically above the corresponding groove of the lower profile part 11, but is offset in contrast.
  • a separate force measurement for the individual rolling disks of the group can be provided, with which the force is measured, which exerts the respective rolling disc on the profile.
  • any commercially available sensors, such as piezoelectric sensors, can be used with the appropriate evaluation electronics.
  • FIG. 4 shows a further preferred embodiment for producing a further profile shape, in which the web 13 is offset relative to the web 14 down.

  • the position shown results in which these rolling disks of group 2, as seen in the figure, come to lie below the corresponding rolling disks 6 and 7 of group 3.
  • This adjustment of both rolling disks 4 and 5 can be accomplished simpler and more precisely by the corresponding adjustment of the respective axles 18 and 19 or their brackets than the adjustment of two rolling disks on a common axis, which is structurally complex and has problems with the coplanar position of the rolling disks can result.
  • a preferred embodiment of the bearing units for corresponding adjustment of the axes / shafts is in FIG. 7 shown.
  • FIG. 5 and 6 show an embodiment of the adjustment according to FIG. 3 , in which thus the one rolling disk in the transverse direction to the enlargement or reduction of the passage opening for the profile is adjustable.
