Definitions

  • the invention relates to a method for making perforations in those areas of a profile serving as a spacer for insulating glass panes, which extends in the position of use transversely to the two glass panes and faces the space between the glass panes, said holes being pressed again after the perforations have been made.
  • the invention further relates to a device for performing this method with a perforation tool or the like, which at the same time deforms the surface to be perforated in the direction of penetration of the tool.
  • the invention also relates to a spacer frame for insulating glazing, which is formed from one or more hollow profiles and contains a desiccant on the inside and is perforated on the web facing the inside of the pane.
  • a frame-shaped spacer for insulating glazing which is formed by a closed hollow profile and the webs facing the space between the two glass panes have openings so that air between the space between the glass panes and the interior of the hollow profile, in which there is a desiccant that can circulate.
  • the openings are formed by parallel short incisions, the material web located between these two cuts being deformed and bent into the interior of the profile in order to enlarge the slots. So that these openings are not too large and remain, this middle area can be pushed back.
  • the method mentioned at the outset is characterized in that the perforation area is deep-drawn when punching in the direction of the interior of the profile and the deepest point of this deformation is pierced and that the deep-drawn area is then rolled such that the depth of the deep-drawing is reduced and thereby the perforation is closed in a dust-tight manner and a nub directed into the interior of the profile is formed.
  • the perforation or perforation area can be formed with an optically inconspicuous small "inner courtyard” by means of deep-drawing. At the same time it is achieved that the perforation itself does not become too large, but the repressing can be carried out easily and thereby a vapor permeability, but not the Since the deepening of the material area located at the deepest point of this deep-drawing process at the same time reduces its thickness, this area can be penetrated relatively easily without making the formed recess too large.
  • the main advantage is that the pressed perforation is in the use position on an upper horizontal frame leg higher than the lower, facing the space between the panes of this frame leg, so that even the finest dust, which could be between the drying agent grains, on the inside of this web sinks and lies deeper than the perforation.
  • the knobs can be deep-drawn to such an extent that, after being pierced and pressed together, they protrude at least about 0.2 mm from a web of the hollow profile that has them, that is to say with a clear protrusion.
  • the deep-drawn area can simultaneously be formed into an essentially convex knob. This is not only relatively inconspicuous on the visible side of the Ab stand frame, but by the knob shape the edges of the perforation can be bent back to each other and brought into contact with each other, so that steam and air can get through, but not dust particles.
  • the device for performing the above method is characterized in that a profiled roller is provided for closing the perforation perforation, which is seated on both sides of the perforated and deep-drawn area on the workpiece and has a circumferential groove in the area of the perforation, the depth of which is The height of the knob to be formed corresponds to and which is less than the first deep drawing.
  • the area with the deep draws and perforations lying next to one another can be rolled over, the areas of the roller located on both sides of the circumferential groove being able to run supported on a sheet metal strip, while the grooved area, the deepened areas again due to the smaller depth deformed against the deep-drawing direction and in doing so presses the puncture holes and shapes the knobs to the end.
  • the width or cross-sectional contour of the groove is equal to or less than that of the knobs. Above all, a somewhat small cross-sectional contour can squeeze the knobs with sufficient force and thus cause the perforation to be squeezed accordingly.
  • the groove cross section of the profiled roller can be rounded, channel-shaped or trapezoidal.
  • a trapezoidal shape can ensure that the perforations are closed, because the short side of the trapezoid then acts directly on the "top" of the deep-drawing process and, due to the smaller groove depth compared to the height of the knobs, can roll the perforations to a certain extent.
  • the side flank of the nub can dodge and thus approach the inclined surfaces of the "trapezoid".
  • the roller used to press the perforation holes is guided and supported on the workpiece itself, so that a nub height defined by the groove depth is maintained in the same way for all individual perforations.
  • the roller can simultaneously axify the respective knob area that is being machined, since it presses the workpiece against its base in this respective area.
  • the spacer according to the invention is characterized in that the passage and the connection between the space between the panes and the interior of the hollow profile is provided at the lowest point of a knob-shaped indentation of the hollow profile on its web facing the inside of the pane and that the knobs having the passage each enter the interior of the hollow profile protrude.
  • knobs were originally formed by a deep-drawing process, there are only relatively small deformation areas or “yards” around the deformation on the visible side of the webs, so that these deformations remain optically inconspicuous. Nevertheless, the perforation, which has been closed again, is shifted in height relative to the web facing the space between the panes in such a way that no drying agent crushed to dust or powder due to gravity is perforated by such a perforation, especially on the upper horizontal frame leg in the position of use the hollow profile can escape into the space between the panes.
  • the protrusion of the knobs relative to the inside of the web is greater than at least about a fifth of the diameter of the desiccant grains contained in the spacer frame, e.g. is at least about two to three tenths of a millimeter.
  • a "nub height" relative to the web having it is sufficient to prevent the desiccant dust settling on the web from escaping from the perforation which is actually pressed.
  • Those desiccant grains that, even after being destroyed, still correspond in size to the height of the knobs or slightly less or are even larger, can, however, easily lie on and above the perforated area of the knobs, since they prevent the passage through the closed one Punching is too big from the start.
  • the water vapor contained in the space between the panes due to external influences after the completion of the Islier glass pane is bound by the desiccant more quickly than is possible due to the perforations being closed.
  • a further development of the invention can therefore consist in that individual perforations are left open at larger intervals between pressed perforations. In this way, the air and water vapor can pass through better.
  • the height shift of the actual opening relative to the perforated web which is formed during the production of the perforations, ensures that desiccant material lying on the web Dust cannot get into the inside of the pane through this perforation, because then it would first have to overcome the height that is present even when the perforation is not compressed, which is prevented by gravity alone.
  • the roller has at least one recess on its circumference with a greater depth than on its circumferential groove. If this recess is long enough in the circumferential direction, in each case at least one deep-drawn point is overlapped by this recess with each revolution of this roller and, due to its greater depth, is not or only less pressed, so that in this case the perforation remains largely open and even maintains an even greater distance from the web itself.
  • the method, device and spacer can thus be adapted to different circumstances, e.g. Adjust panes of different sizes and thus different sized spaces between panes so that on the one hand the moisture inside the insulating glass pane during its manufacture can be absorbed by the desiccant sufficiently quickly, but this desiccant, for example, during storage of the spacer frames, does not allow too much moisture from the environment records.
  • the special shape of the perforation and its height in relation to the web prevent drying agent dust from escaping into the space between the panes.
  • a spacer frame for insulating glazing is essentially bent from a curved hollow profile 2, in the interior of which drying agent 3 is arranged.
  • the web 4 of this hollow profile 2 facing the window interior is perforated in a manner to be described, so that an air exchange can take place between the interior of the hollow profile 2 and the window space 5.
  • the protrusion 8 of the knobs 7, indicated above all in FIG. 5, with respect to the inside of the web 4 is larger than at least about one sixth of the diameter of the desiccant granules 3 contained in the spacer frame 1 and can e.g. about two to three tenths of a millimeter. Depending on the application, however, this protrusion can also be half a millimeter or even a whole millimeter, which also depends on the material thickness of the web 4 and the cross-sectional size of the hollow profile 2.
  • FIGS. 1 to 5 A device for attaching the perforations and thus the passages 6 is at least partially indicated in FIGS. 1 to 5.
  • the tools with which are not shown. the surface of the web 4 to be perforated or perforated is simultaneously deformed or deep-drawn in the direction of penetration of this tool.
  • a profiled roller 9 serving as an essential part of the device for pressing the perforation 6a which can be seen in FIG.
  • this roller 9 according to FIGS and 3 is seated on both sides of the perforated and deep-drawn region of the web 4 and in the region of the perforation 6a has a circumferential groove 10, the depth of which corresponds to the height of the knob 7 to be formed, whereby this depth of the groove 10 is less than the first deep drawing 7a according to FIG. 1.
  • the width and cross-sectional contour of the groove 10 is equal to or smaller than that of the knobs 7.
  • the groove cross section is channel-shaped and can be rounded according to FIG. 2 or trapezoidal according to FIG. 3.
  • the short side 10a of this trapezoid of the trapezoidal groove 10 can act particularly well on the area of the first perforation 6a from above, while at the same time the inclined surfaces 1b of the trapezoidal groove 10b cause an action from the side, so that it is compressed and compressing the perforation 6a to the only vapor-permeable passage 6 is compressed.
  • such deep-drawn deformations 7a which are deformed into knobs 7, are arranged in a row next to one another in a row. If in some cases a greater air and vapor permeability of the hollow profile 2 is to be maintained, individual deformations 7a could now remain unchanged, i.e. their perforations 6a could be left out of the process of being squeezed and thus remain open in the manner shown in FIG. 1. This could be caused by the fact that the roller 9 has at least one recess with a greater depth on its circumference than on its circumferential groove 10. Those deep-drawn sections 7a which are overrun by this recessed area of the roller 9 then remain open at the perforation 6a or are only slightly compressed, so that more air can be exchanged there.
  • the perforation area during the perforation is deep-drawn in the direction of the interior of the profile 2 and the deepest point of this deformation 7a according to FIG. 1 is pierced. Then the deep-drawn area is rolled in such a way that the depth of the deep-drawing is reduced and thereby the perforation 6a is closed in a dust-tight manner and a knob 7 directed into the interior of the profile 2 is formed.
  • a flat sheet metal strip can first be deep-drawn, punched and the perforation 6a pressed, after which the sheet metal strip can then be roll-formed into the profile 2.
  • a flat sheet metal strip can be better provided with deep-drawing deformations and perforations 6a and can also be rolled again at these perforations 6a, because the profile roller 9 then also has a good abutment for its areas located on both sides of its groove 10. It is advantageous that when the perforation 6a is rolled and closed, the deep-drawn region 7a is simultaneously formed into an essentially convex knob 7.
  • the initially gaping edges of the perforation 6a can thus be bent towards one another and can also be brought closer to one another, as is shown enlarged in FIG. 4. Any irregularities in the perforated edges can then even be interlocked as shown in FIG. 4, so that the vapor permeability is retained, but the passage of particles is made even more difficult.
  • the perforation area is first deep-drawn in the direction of the interior of the profile 2 and the lowest position of the deformation 7a thereby created is pierced. This deep-drawn area is then rolled in such a way that the depth of this deep-drawing is somewhat reduced and the perforation 6a is thereby closed in a dust-tight manner.
