Definitions

  • the invention relates to a method for bending hollow spacer profiles, in particular filled with desiccant, for glass panes to be kept at a distance, preferably insulating glass panes, the profile being pushed forward and pressed against an abutment during bending and bent behind this abutment with a bending tool or a bending jaw.
  • the invention further relates to a device for bending hollow spacer profiles, preferably filled with desiccant, for glass panes to be kept at a distance, preferably insulating glass panes, with an abutment and a pivotable bending tool or the like which bends the profile relative to the abutment.
  • the object is therefore to create a method and a device of the type mentioned at the outset by means of which any bends with different radii of curvature and possibly also radii of curvature which change in the course of an arc can be produced.
  • the procedural solution to this task consists essentially in that the profile is advanced during the bending and the bending tool is moved oscillatingly towards and away from the abutment, and in particular during its movement away the profile is moved and with the next movement towards the abutment opposite a neighboring point of the profile the previously bent point is acted upon and bent.
  • the feed and the amplitude of the movement of the bending tool or the bending jaw it is possible, by choosing the feed and the amplitude of the movement of the bending tool or the bending jaw, to obtain an arbitrarily large or relatively small curvature on such a spacer profile. Since this is always shifted a little further during such a bending process, such a bend is practically composed of numerous immediately adjacent bending points.
  • the feed rate and / or the frequency of the back and forth movement of the bending tool and / or the respective swivel path or the amplitude of the bending tool can be changed, preferably computer-controlled. It is possible that the frequency of the back and forth movement is chosen between 1 Hertz and about 30 Hertz.
  • the device for bending such spacer profiles with large, but also small or changing radii of curvature to solve the problem mentioned above is characterized in particular in that a feed drive for the profile - in particular in the feed direction in front of the abutment - is provided and that the bending tool an oscillating , reversible swivel drive for a back and forth bending swivel movement.
  • a feed drive for the profile - in particular in the feed direction in front of the abutment - is provided and that the bending tool an oscillating , reversible swivel drive for a back and forth bending swivel movement.
  • Bending tool has a reversible drive acting on the geometrical bending axis above or below the abutment for the stepwise forward and backward stroke.
  • the shaft arranged in the bending axis or its extension for the back and forth swiveling movement of the bending tool can be controlled and reversed by a rotary encoder connected to a microprocessor or computer.
  • This also allows arcs and bends to be selected and preprogrammed that deviate from simple circular arcs in any way, which deviation could be regular if such an arc shape is to be a piece of a spiral, or it can also be uneven if it is within one Arc areas with smaller or larger radii of curvature should be provided or even alternated.
  • the rotary encoder is expediently arranged coaxially with the shaft for the back and forth movement. As a result, transmission means from the rotary encoder to this flexible shaft can be avoided.
  • a preferably pneumatic swivel drive can be arranged in particular via a shaft which acts on a lever arm and is arranged in the bending axis.
  • pneumatic rotary actuators are commercially available per se and for Such a reciprocating movement of the bending tool is particularly simple and inexpensive.
  • the profile guide and in particular its width can be adjustable.
  • a device designated as a whole by 1 and shown schematically in FIGS. 1 to 3, is used to bend hollow spacer profiles 2, possibly filled with desiccant, for glass panes to be kept at a distance, in particular insulating glass panes.
  • This device 1 has in the bending area of the profile 2 an abutment 3, opposite the contact area 3a, the profile 2 is bent in a manner to be described.
  • the device includes a pivotable bending tool 4 which bends the profile 2 relative to the abutment 3 in the form of a bending jaw.
  • This bending tool 4 is in the starting position with its contact surface 4a, which acts on the profile 2 during bending, in alignment with one side of a profile guide 5, through which the profile 2 is fed to the bending tool 4 according to the arrow Pf1.
  • This arrow Pf 1 also indicates that the device 1 has a feed drive, not shown, for the profile 2, which is preferably arranged in the feed direction in front of the abutment 3.
  • the bending tool 4 in turn has an oscillating, reversible swivel drive 6 for a back and forth bending swivel movement according to the double arrows Pf2 and Pf3 in Fig. 3. This oscillating back and forth The movement of the bending tool 4 is also shown in FIGS. 6 and 7 for different cases over time in a diagram.
  • the profile 2 can thus be advanced during the bending and the bending tool 4 can be moved oscillatingly towards and away from the abutment 3, the profile 2 especially during the movement of the bending tool 4 away from the abutment 3 in the direction of arrow Pf1, that is, in the direction of advance, moved further, and with the next movement of the bending tool 4 towards the abutment 3, a neighboring point of the profile is acted upon and bent relative to the previously bent point.
  • the bending tool 4 has a reversible drive 6, which acts on the geometric bending axis 7 above or below the abutment, in this case below the abutment, for the stepwise forward and backward stroke.
  • a commercially available pneumatic swivel drive is indicated as drive 7.
  • the shaft 8 arranged in the bending axis 7 or its extension for the back and forth pivoting movement of the bending tool 4 is coupled by a rotary travel encoder 10 connected to a microprocessor 9 or computer and is thus controllable and reversible on a pulse basis.
  • the back and forth movement can be changed in any way, both in terms of amplitude and frequency, so that in cooperation with a possible simultaneous adjustment or modification of the feed speed, almost any arc shapes and bends can be connected to each other in any order, but of course constant large or small bends can be put.
  • the rotary encoder 10 is in this case arranged coaxially to the shaft 8 for the reciprocating movement, so that a direct coupling can be achieved without intermediate transmission elements, whereby the device is simple in construction.
  • the pneumatic swivel drive 6, which is pneumatic in the exemplary embodiment, is arranged between the rotary encoder 10 and the shaft 8 which acts on the bending jaw or the bending tool 4, in particular via a lever arm 11 and is arranged in the bending axis 7.
  • Fig. 1 it can be seen that the profile guide 5 is provided for fixing the position of the profile 2 during its feed in the feed direction in front of the abutment 3.
  • This profile guide 5 for the profile 2 has a game 12 and 13 as shown in FIG. 1 compared to the profile itself.
  • the profile 2 can be advanced practically without resistance through this profile guide 5, so that the bending process which is also dependent on this feed is not impaired
  • the game 12 and 13 is exaggerated for clarity.
  • rollers 14 are provided according to FIG. 1 for bridging the play 13 relative to the profile 2.
  • FIG. 2 shows an arrangement for a profile 2 that is closed on all sides and has a protrusion free in its cross section, while in the profile according to FIG. 3 the side webs 2a are somewhat extended via a crossbar 2b.
  • a further adaptation possibility can consist in the fact that the profile guide 5 and in particular its width can be adjustable to adapt to profiles of different dimensions.
  • the device 1 also allows the following configurations of this method: Initially, the bending movements of the bending tool 4 can be chosen to be smaller than in the further course of the bending process. This can also be seen, for example, from FIG. 6, according to which smaller strokes can be seen at the start of the time axis than if the bending tool can then oscillate back and forth according to the arrow Pf3 in FIG. 1 after a certain starting range.
  • FIG. 1 illustrates a start-up area within which the bending jaw 4 initially carries out smaller strokes until it has finally reached the outermost end of the arrow Pf3 in the bending direction, from where it then only ever moves up to swinging back to the opposite end.
  • Fig. 6 five start-up strokes are shown purely schematically and then continuously high-speed constant-lift strokes with constant amplitude.
  • the method according to the invention can be designed such that the arc 17 of the profile 2 by means of the reciprocating bending tool 4 during the feed of the profile 2 is bent and that to form the sharp bending edge at point 15 the feed of the profile is reduced or even interrupted and the bending tool is actuated when the profile 2 is stationary or almost stationary.
  • the corresponding time-stroke diagram is shown in FIG. 7. At the beginning of the course of time, a higher stroke can be seen, which serves to form the sharper corner in the area 15, while then, when the bending tool 4 swings back and forth uniformly, the arches 17 are produced with corresponding strokes.
  • the feed rate for the profile and / or the frequency of the back and forth movement of the bending tool 4 and / or the respective pivoting path or stroke of the bending tool 4 changed preferably computer-controlled.
  • the frequency of the back and forth movement can be selected between 1 Hertz and about 30 Hertz and - as already mentioned - can also be varied within this range under certain circumstances.
  • FIG. 4 is one compared to FIG. 5 shows somewhat modified spacing frame, in which the arcuate transition 17 tangentially merges from a straight frame part 16, the first part of this transition possibly also being a part of a gradually narrowing curve until the radius of curvature of the arc 17 is then reached. There would then be a short piece of a spiral arch at the transition between the frame part 16 and the arch 17.
  • the device 1 according to the invention and the method according to the invention also allow the production of completely round or oval spacing frames or also all conceivable variations in between, so that a correspondingly diverse design of insulating glass panes is made possible without this becoming unaffordable with regard to frame production.
