Definitions

  • the invention relates to a method for producing curved sections in hollow profile strips.
  • One-piece, with more or less sharp-edged corners made of hollow profile strips spacer frames and devices for producing the same are from DE-GM 87 05 796, DE-PS 32 21 881, US-PS 4,836 005, FR-PS 2,449 222 and DE-OS 32 21 986 known.
  • DE-OS 33 12 764 from which it is known to bend hollow profile strips to form spacers for insulating glass panes, a mandrel which can be placed against the hollow profile strip from the inside being provided in the region of the bending point.
  • the bending is carried out by pivoting a jaw, the other end of the profile strip being clamped between a movable clamping jaw and an abutment resting on the inside of the profile strip.
  • a problem with the known bending devices is that the sharp-edged bends required for use in insulating glass panes cannot always be achieved without problems, since there is sometimes a risk that the walls of the hollow profile strip will tear during the bending process and the side surfaces of the hollow profile strips in the corner area, ie where they have been bent, they do not always run flat, but have corrugations which make subsequent processing of the spacer frame, in particular the coating of the side surfaces of the spacer frame with sealant or adhesive, more difficult and hinder.
  • DE-AS 21 28 717 discloses a method for applying a metallic spacer to the pane edges of one of the rectangular glass plates of an insulating glazing.
  • the spacer is continuously brought into contact with a pane-parallel surface on a first pane edge of the horizontally lying glass plate and then fastened.
  • the spacer with a surface parallel to the disc is placed on the next edge of the disc and fastened.
  • the procedure is such that after the spacer is attached to a pane edge, but before it is pivoted, the glass plate is displaced parallel to this pane edge by a distance corresponding to its length, that the pivoting of the glass plate takes place in each case about an identical fixed pivot axis and that the spacer is bent about this pivot axis.
  • the spacer is initially only arranged over part of the length of the first pane edge and the spacer is cut off with a protrusion after it has been attached to the pane-parallel surface of the last pane edge. Only then is the protruding part bent around the pivot axis of the glass pane by 90 ° and attached to the glass pane.
  • EP-A-332 049 it is known to bend hollow profile strips to form spacers for insulating glass panes.
  • the profile is advanced during the bending and a bending tool is oscillatingly moved to and from the abutment, the profile being advanced during the movement of the bending tool and a neighboring point of the next movement of the bending tool towards the abutment Profiles towards the previously bent point is acted upon and bent.
  • different arches and radii of curvature can be generated.
  • Bending machines for hollow profile bars which are equipped with rollers, are also known.
  • DE-OS 30 34 436 describes a roll bending machine which has three rolls, the hollow profile bar being held in contact with the third roll by two rolls.
  • the radius of the curvature in the hollow profile rod corresponds to the radius of the third roller around which the hollow profile rod was bent.
  • the object of the invention is to provide a method and a device with which continuously curved hollow profile strips are produced can be, the radii of curvature and the length of the curved portion of the hollow profile bar are largely arbitrary.
  • This object is achieved in a method of the type mentioned in that the profile is supported under a hold-down device between guide jaws, supported from below, and that the profile is deflected after the hold-down device from the conveying direction of the hollow profile bar.
  • the method according to the invention has considerable advantages over the operation of previously known bending devices. In this way, unlike in EP-A-33 20 49, continuously (continuously) curved sections can be produced.
  • the invention has the advantage that the radius of curvature and / or the length of the curvature can be set very easily.
  • Another advantage is the proposal according to the invention to effect the deflection with the aid of a run-up surface instead of with rollers as is known. This is particularly so in view of the fact that the run-up surface as part of the pivotable bending lever can then be easily adjusted to the desired deflection angle.
  • the hollow profile strip to be curved is advanced by a feed device, which is advantageously designed as a gripper or has a gripper.
  • a feed device which is advantageously designed as a gripper or has a gripper.
  • this saves drives for the rollers, as are necessary for the known devices, and offers the advantage over pulling the hollow profile strip that curved or bent regions (corners) produced therein are not deformed again.
  • the hollow profile strip to be bent into the spacer frame is pushed exactly by the feed device (gripper) during the bending process by the required distance, which e.g. corresponds to the respective curved section of the spacer frame. If the length of the curved section is greater than the maximum stroke of the gripper, the profile strip is advanced in two or at most more than two steps.
  • the procedure can be such that the first (or the first) stroke (strokes) correspond to a predetermined length (the maximum stroke) and the last stroke is adapted to the required length of the curved frame section.
  • a hollow profile bar 53 is transported on a conveyor track 54, which is arranged at the lower end of a support wall 60, up to a stop 57 in the region of a bending point 58/59.
  • the stop 57 can also be arranged in front of the bending point so that it can be lowered into the conveyor track.
  • the stop 57 can be equipped with a switch which stops the feed conveyor (not shown) and triggers the gripping 51 to grip the hollow profile bar 53.
  • the hollow profile bar 53 is gripped by the gripper 51 in a precisely defined position.
  • the transported over the bending point 58/59 section 53 'of the hollow profile bar 53 is bent against the support wall 60 by the bending lever 59 around an abutment 58 around.
  • the bending point preferably has the construction described below with reference to FIGS. 3 to 8.
  • the device can for example have the structure known from DE-GM 87 05 796 and have a support finger (indicated in FIG. 9), as is also provided in the known device.
  • the device shown in FIGS. 3 to 8 for bending hollow profile strips 53 consists of a clamp 2 with a stationary jaw 3 and a jaw 4 which is movable relative to this (the jaw 4 is not shown in FIG. 3).
  • the movable clamping jaw 4 is displaceable in the direction of the double arrow 7 via guide pins 5 and 6, which are each arranged in pairs, so that the mouth width of the clamp 2 can be adapted to the width of the hollow profile strip 53 to be bent.
  • a lever 8 is provided which is pivotably supported on the fixed clamping jaw 3 and which is connected via a pull rod 9 via a bearing 10 is pivotally supported on the movable jaw 4, is coupled.
  • the pivot lever 8 is actuated by a linear motor, not shown, for example a double-acting pressure medium cylinder.
  • the bending device also has a hold-down 20, which serves as an abutment during bending.
  • the hold-down device 20 is interchangeably inserted in a carrier 21.
  • a groove 23 is recessed in the carrier 21, into which the hold-down 20 can be inserted with a sliding fit and is held, for example, by a screw 24.
  • the bracket 21 for the hold-down 20 is mounted on a lever 25 which is about a bearing 26 fixed to the machine frame, i.e. a bearing, which is not movable relative to the stationary jaw 3 of the clamp 2, with the aid of a linear motor 27, e.g. a double-acting pressure medium cylinder, can be pivoted in the direction of the double arrow 28 from the active position shown in solid lines in FIG. 3 into the ready position shown in dash-dotted lines in FIG. 3.
  • a linear motor 27 e.g. a double-acting pressure medium cylinder
  • the carrier 21 for the hold-down device 20, as shown in FIG. 4 is adjustable perpendicular to the plane of symmetry of the clamp 2, namely in the direction of the double arrow 29 shown in FIG. 4.
  • the carrier 21 is guided displaceably via guides 30 in a holder 31 connected to the lever 25.
  • a linear motor in the exemplary embodiment shown a double-acting pressure medium cylinder 32, is provided, the piston rod 33 of which is coupled to the support 21 via a pull rod 34.
  • the hold-down device 20 can not only be pivoted in a plane parallel to the plane of symmetry of the clamp 2 (double arrow 28), but also in a direction perpendicular to the plane of symmetry of the clamp 2 (double arrow 29), so that the hold-down device 20 can be completely moved out of the bending area.
  • the hold-down 20 carries at its front end, which is formed by two inclined surfaces 36, which form an acute angle to the longitudinal extension of the hold-down 20, a bead-like extension 35, which like Fig. 6 shows that the upper surface of the hollow profile 53, which is clamped in the clamp 2 between the jaws 3 and 4, bulges slightly before the start of the bending process when the hold-down device 20 is pivoted into its active position.
  • the front end of the hold-down device 20 and the bead-shaped extension 35 adjoining the inclined surfaces 36 there are made somewhat narrower than the clear distance between the mutually facing surfaces of the clamping jaws 3 and 4 of the clamp 2 the side walls 40 of the hollow profile strip 53 to be bent are also supported from the inside during the bending process, as is indicated in the section of FIG. 7.
  • an angled stop surface 41 is provided on the hold-down device 20 in the area of its front end on one side, which cooperates with a step 42 on the fixed jaw 3. If the stop surface 41 abuts the step 42 of the clamping jaw 3, then the axis 37 of the bead-shaped extension 35 provided at the front end of the hold-down device 20 is correctly aligned.
  • the device for bending also has a bending lever 59 with a bending attachment 62 which can be pivoted about an axis which coincides with the axis 37 of the bead 35 at the front end of the hold-down device 20 when it is in its operative position (the surfaces 41 lie against it) the surfaces 42 of the jaw 3).
  • the pivoting range of the bending lever 59 is not limited to the 90 ° shown in Fig. 3, but also goes beyond, so that after pivoting (arrow 28) and lateral displacement (arrow 29) of the hold-down device 20 also acute angles between the two the corner 61 of the hollow profile bar 53 which is produced in the hollow profile bar 53 can be bent.
  • the clamp 2 When using the device for bending a hollow profile bar 53 to a corner 61, the clamp 2 is opened and the hollow profile bar 53 is placed on the upper guide pins 6 or transported on the conveyor track 54 to the pins 6. After closing the clamp 2, the inner surfaces of the jaws 3 and 4 are then on the side surfaces 40, the hold-down device 20 is moved into its operative position shown in FIGS. 3 and 6 and thereby bulges the upward-facing wall of the hollow profile strip 53 somewhat down one. Then, by pivoting the bending lever 59, the portion 53 'of the hollow profile bar 53 projecting from the clamp 2 is pivoted to form a corner 61. If the angle at the corner 61 is to be more acute, the hold-down device 20 is pivoted back and pulled back laterally, whereupon the Bending continues until the desired angle.
  • the bending lever 59 is pivoted back, the clamp 2 is opened and the hollow profile bar 53 is advanced by the gripper 52 until the location of the hollow profile bar 53 in which the next corner 61 is to be produced is correctly aligned with the bending tool and then, as described above, the next corner 61 is bent. This continues until a spacer frame with the desired number of corners 61 - usually four - is finished.

  • the hollow profile bar 53 is thus in a “zero” position.
  • the gripper 52 mounted on the slide 51 holds the hollow profile bar 53 in place.
  • the stop 57 is now sunk into the conveyor track 54 and the slide 51 with the profile 53 clamped by the gripper 52 now moves in the direction of the bending lever 59 exactly by the distance that a process computer specifies and that corresponds to the length of the frame leg.
  • the effectively traveled length is determined by an incremental encoder 56.
  • An incremental encoder 56 determines the exact measurement of the distance traveled by the carriage 51, and the movement of the carriage 51 is controlled by the latter.
  • the incremental encoder 56 is mounted on the drive motor 55 or on the movement 54 of the slide 51.
  • the carriage 51 is driven, for example, by an endless toothed belt and is guided on a guide running parallel to the conveyor track 54.
  • the engagement of the toothed belt in the drive gear of the drive motor 55 is exact and free of play, so that an incremental encoder 56 mounted directly on the motor-gear unit can also accurately record the distance traveled by the slide 51.
  • the effective travel distance of the slide 51 corresponds to the profile length which the process computer determines for a bending process.
  • the drive motor 55 does not have to be fixed in place, but can also be arranged on the slide 51.
  • the drive gear of the drive motor 55 then engages in the toothed rack fastened to the guide 54 of the slide 51, it being possible for an incremental encoder 56 to also be mounted on the drive motor 55 or on the slide 51.
  • the conveyor track 54 can be a simple slideway.
  • a hollow profile bar 53 is so far advanced by a conveyor that can be, for example, the carriage 51 with the gripper 52, for example, starting from the reference position, which is determined by the fitting 57, that the portion 53 'of the hollow profile bar projecting over the hold-down device 20 53 corresponds to the reduced length of the first leg of the spacer frame to be produced by a certain distance "x".
  • This position is shown in Fig. 9b.
  • the jaws 3 and 4 lie against the hollow profile bar 53 and the slide 51 returns to its starting position, which is shown in FIG. 9a.

  • the jaws 3 and 4 close again and hold the hollow profile bar 53 immovably and the next (second) bending process is carried out with the aid of the bending lever 59, while the carriage 51 returns to its starting position.
  • the slide 51 moves forward with a gripper 52 placed on the hollow profile bar 53 by a distance which corresponds to the length of the next leg of the spacer frame to be produced, so that the next (third) bending point is aligned with the hold-down device 20 .
  • the jaws close 3, 4 again and hold the hollow profile bar 53, whereupon the third bending process is carried out.
  • the jaws 3 and 4 are released again from the hollow profile bar 53 and the slide 51 moves again with the gripper 52 applied to the hollow profile bar 53 so far that the next (fourth) bending point is exactly opposite the hold-down device 20 is aligned.
  • this stroke corresponds exactly to the stroke before the execution of the second bending process.
  • the jaws 3 and 4 close again and hold the hollow profile bar 53 in place.
  • the hollow profile strip 53 is cut off at the point indicated by the arrow 170 (FIG. 9e).
  • the length of the piece of hollow profile bar 53 thus obtained in FIG. 9e to the left of the hold-down device 20 corresponds exactly to the predetermined distance "x" by which the hollow profile bar 53 was advanced less than the length of the first one before the first bending operation (FIG. 9b) Leg (Fig. 9b) corresponds.
  • the fourth bending process is carried out, the front end 172 of the supplied hollow profile bar 53 and / or the section 173 of the partially finished spacer frame being deflected out of the bending plane or the front end 172 simply being moved down so that the fourth bending process is not hindered.
  • the ends of the hollow profile strip 53 which are adjacent to one another at the joint 171 (FIG. 9f), are Completed spacer frame transported away from the device after the jaws 3 and 4 are loosened again and the hold-down device 20 have been removed from the bending plane.
  • the ends of the hollow profile bar 53 which are adjacent to the joint 171 at the spacer frame are connected to one another by inserting a connector or by butt welding.
  • a welding device suitable for this purpose is known, for example, from EP-AO 192 921.
  • a hold-down device 80 is inserted into the carrier 21 of the tool and has a freely rotatable roller 70 at its free end facing the hollow profile strip 53 (Fig. 10 to 17). Through this roller 70, the hollow profile bar 53, which is guided between the jaws 3 and 4 - i.e. the jaws 3 and 4 no longer clamp the hollow profile strip 53 - held against the guide rods 6 serving as support from below.
  • spacer frames with at least one corner 61 and with at least one curved section 71 are to be produced (see FIG. 22), it is also possible to use a hold-down device without a freely rotatable roller 70, i.e. can be worked with a hold-down device 20, as shown in FIGS. 3 to 8, which has a projection at its front end similar or identical to the projection 35, or as described further below with reference to FIGS. 19 to 21 , is trained.
  • the bending lever 59 is so inclined when generating curved sections 71 in hollow profile strips 53 relative to the conveying direction of the hollow profile strip 53 according to the desired radius of curvature, so that the hollow profile strip 53 emerging between the jaws 3 and 4 from the bending attachment 62 on the bending lever 59 upwards is deflected and continuously curved.
  • the width of the roller 70 is somewhat narrower than the width of the hollow profile bar 53 to be curved, so that the inner wall of the hollow profile bar 53, as can also be seen in FIG. 16, is deformed inward during the bending process. This reduces the compression of the inner wall of the hollow profile bar 53, so that there is a largely smooth inner wall in the curved section 71 of the hollow profile bar 53.
  • FIG. 18 A particularly favorable embodiment of a gripper 51, which ensures the necessary frictional engagement for the precise advance of the hollow profile strip 53 to be curved, is shown in FIG. 18. It can be seen that the lower jaw 75 is rigidly connected to a carriage 76 guided in the conveying direction on at least one guide rail, whereas the upper jaw 77 can be pivoted away from the jaw 75 via parallelogram link 78 by a pressure medium motor 79. The movable jaw 77 can therefore be pivoted behind the support wall 60 of the device so that it does not hinder the removal of a finished bent spacer frame.

  • spacer frames with at least one sharply bent corner with any angles between the legs of the spacer frame adjacent to the corner 61 and with at least one curved section 71 can be produced from one and the same hollow profile strip 53.
  • both a hold-down 80 and a hold-down 20 can be mounted on the carrier 21. These tools are then occasionally moved into the active position, which is symmetrical to the jaws 3 and 4. This is not a problem, since the carrier 21, as described above with reference to FIGS. 1 to 8, can be raised and adjusted transversely to the bending plane.
  • FIGS. 19 to 21 corresponds essentially to the device described with reference to FIGS. 10 to 17, but instead of the freely rotatable roller 70, a slide 81 is inserted in the hold-down device 80, through which the inner wall of the hollow profile strip 53, such as 21 can be seen inwardly deformed during the bending.
  • Both the hold-down device 80 with the roller 70 and the hold-down device 20 with its extension 35 are in the conveying direction, i.e. adjustable parallel to a plane connecting the guide pins 6.
  • the position of the hold-down devices can thus be adapted to the geometric conditions which result after changing the angular position of the lever 50 with the ramp surface 62.
  • hollow profile strips 53 can also be bent to form spacer frames for insulating glass panes which have at least one sharp-angled corner 61 and at least one section 71, for example curved according to a partial arc.
  • An example of such a frame is shown in FIG. 22.
