PROCEDURE AND APPARATUS FOR MANUFACTURING COMPOSITION PROFILES FOR WINDOW FRAMES, DOOR FRAMES, FACADE CONSTRUCTION OR LIKE.

The invention relates to a method of producing a composite profile for window frames, door frames, facade structures and the like consisting of at least two spaced apart, in one piece of metal profiles, which face each other on the inside. have projections, undercuts and the like, whereby the metal profiles over their length are connected to each other by insulation core moldings of poorly conductive material which are separated from each other by a cavity, and the metal profiles are separated by removable flanges which strike 15 bridge the distance between the metal profiles and the flanges. forms unilaterally open bottom compartments in which, to form the insulating core moldings, a thermoplastic resin mold is inserted from above into the gutter, which is therefore cured, thereby casting the composite profile first in a first gutter, and after curing the molding mold. The composite profile is inverted about its longitudinal axis so that the gutter (s) located below it is placed at the top and then cast, and at which the flange bridging the distance between the metal profiles is removed.

In a method of this kind known from DE Publication No. 29 04 192, the metal profile, after filling and subsequent curing in the upper gutter of 30 cast resins, is rotated around its longitudinal axis and in such a way that the opposite gutter which is separated from the the first at the cavity can be filled with cast resin. Thereafter, a tool is inserted into the cavity bounding the metallic bonding flanges and removing the bonding member.

It has been found that this known method can only be used in a limited number of different composite profile cross-sectional forms. Thus, difficulties arise, for example, in the production of composite profiles, in which the cross-section of the cavity falls below a certain free dimension, so that there is not always enough space to introduce and handle the tool for removing the joint joints.

10

In addition, in order to use the known method, special tools are required, the scope of which is so limited, so that with such systems it is not possible to produce, for example, very small profiles having only a metallic bonding flange or profile cross-sections having more than two overlaid insulation core moldings.

The object of the present invention is to provide an economical method by which composite profiles of small cross-sectional dimensions as well as large profile sections can be produced, regardless of whether they have one or more metallic bonding flanges. A further object of the invention consists in providing a suitable device for practicing the method.

Starting from a method of the kind mentioned in the preamble, this is achieved according to the invention in that before the turning is removed the flanges / flanges of the metallic seam cover and after the turning, but before the filling of the additional gutter (s). / grooves, a metal section is formed between the metal profiles above the insulation core / s first formed (s) as a separate part of poorly conductive material which forms the bottom of the outer (s).

render / render.

In the method according to the invention, it is possible to produce reconstituted profiles of both small and large cross-sections in a continuous operation. By removing the metal connections between the profiles at an early stage before the metal profile is reversed, it does not matter that the starting profile cross sections have one or more metal bonding flanges, so that they no longer depend on the cross-sectional size of the cavity which confines -see the height of the insulation core strip. In addition, the process of the invention has made it possible to make the present manufacturing plant universally usable by a simple conversion. Instead of using, as in the known method, the tool to be inserted into the composite profile cavity to be able to remove the bonding flange, the saws or milling machines normally available in the business can be used.

20

In a further development of the method according to the invention, after filling the first molded gutter and before removing the holding flange parts and reversing the metal profile, at least one list 25 'of a material which is a poor heat conductor can be placed above the first formed insulating core strip between the metal profiles, which forms the bottom of a second channel filled with plastic material. This makes it possible to make special profile shapes with more than two mutually arranged insulating core moldings.

When making composite profiles with more than two adjacent metal profiles, the removal of the metallic bonding flanges takes place temporarily.

one after the other in order to achieve a better power distribution during this machining process.

In cases where space conditions require, the composite profile is suitably transferred after turning to another transport line and transported thereon in a direction opposite to the direction of feeding of the first transport line.

Devices for transferring artificial resin concrete articles from a first conveying web to a second conveying web having the opposite conveying direction are known in principle from DE Publication No. 24 46 666. Preferably, the turning and surrendering of the composite profiles to the second conveying web are carried out simultaneously. The device for exiting 15 of the method, which in its basic structure is based on the device known from the applicant from DE patent application 29 13 254, and which has a support supporting the metal profiles as well as transport and feeding devices for the metal profiles for passing these under a first molding device, and at least one further molding device disposed thereafter, and a further two successive molding devices disposed in the direction of inserting a separating molding between the metal profiles, as well as a device for removing one or 25 more metallic bonding flanges, characterized in that in the transport direction behind the first molding device and for the separating insertion device, devices for removing the bonding flange (s) are arranged and at a distance behind it a station 30 for reversing the composite profile about its longitudinal axis disposed. A device designed in this way can be obtained with simple means by converting it into commercial plants, so that with one and the same device a universal application is possible. The device according to the invention permits

DK 157040 B

The preparation of composite profiles as well with only one as with a plurality of metallic bonding flanges in a continuous workflow, whereby, for switching from one composite profile cross-sectional form, it is only necessary to connect or disconnect individual aggregates.

Preferably, in the direction of transport, there is provided after the first molding device and before the device for removing the bonding flange (s), an additional device for introducing the separating strips and a molding device. This makes it possible to make large profile cross sections in a practical structure.

Admittedly, in the garnish application of the applicant (DE publication 15 no. 29 41 354) such a connection after each other of individual units has already been proposed in the broadest sense. Since the device for removing the holding flange is thereby placed as the last link behind the last casting device placed in the transport direction, while the device for removing the holding flanges in the device according to the invention is at least prior to the last casting device, the practice of the method is According to the invention, it is not possible with the device proposed in this DE publication.

Preferably, after the first conveyor lane and the friend station, a second conveyor lane with opposite conveying direction is connected to the first one. This method of execution is chosen when the production line must be as short as possible. Advantageously, the turning station consists of a composite profile pivot and a conveyor belt, conveyor roller or similar formed transfer device for transporting the composite

profile from the first transport path to the second transport path.

In the manufacture of composite profiles with multiple insulation zones, there are preferably several transverse directions to the number of desired insulation zones corresponding to spaced casting devices, devices for removing the sanitary flange / flange R.B and separator supply rolls.

In FIG. 7, is an example of a practically preferred, applied profile cross section with only one connecting flange, a finished composite profile. Profile 1 has two spaced apart metal profiles 2, 3. Each metal profile 25 has an elevated edge 4 or the like, which intermeshingly engages each of its insulating core strips 5, 6 of a material which is a poor heat conductor. and extending throughout the length of the metal profiles so as to provide a smooth connection between the metal profiles, which may, for example, be of extruded aluminum. The insulating core ele- ments 5, 6 define together with the inner wall 2 ', 3! a box-shaped cavity 7 which extends throughout the length of the metal profiles and which is separated in one side from the insulation core strip 5 by means of a separating strip 8.

positioning of the composite profile according to FIG. 7, for example, the cross-section according to FIG. 1, if two metal profiles 2, 3 are joined to a unit in one piece by means of a metallic bonding flange 9 which is extruded 5 together with the metal profiles in a working step.

Also used as starting profiles are cross-sectional shapes having two or more joining members 10, 11 and 12, 14, 13, 15 (Fig. 8 and 10, 10) and 10, 11, 23 '(Fig. 11, respectively). or 10 ', 11' (fig.

13) and have the advantage of providing better stability and good measurement tolerances during the extruding process. This advantage is particularly prominent in large profile cross sections.

However, even with small profiles, exit cross sections are often required, which have more than one connecting flange between two metal profiles. In FIG. 9 and 10, there is shown an output profile section with three adjacent metal profiles 2, 3, 3 ', of which the metal profiles 3, 3' are joined together by a holding flange 12 and the metal profiles 2, 3 'by means of a matching length 13.

It will be seen that the bonding flanges 12, 13 are arranged apart from each other by the metal profile 3 '. It is also possible in each insulation zone A and B at the time, for example, according to FIG. 9 and in the end of the embodiment according to FIG. 8 to provide two or more bonding flanges instead of one, as indicated by the cross-section of FIG. 10 by dotted lines 14, 15.

In FIG. 11, a variant of an output cross-section is shown with two interconnecting flanges 10, 11 arranged one above the other, whereby the finished composite profile according to FIG. 12 instead of two insulated core moldings arranged above, three insulation core moldings 16, 17, 18. Further, a variant of the composite profile with three insulation cores is provided.

DK 157040 B

core strips 16 ', 17', 18 'are shown in FIG. 22. This embodiment of the composite profile is preferably used in practice to produce relatively large cross-sections whose starting profile cross sections have two or more metallic bonding flanges 10 ', 11', 11 * 'as shown in FIG. . 13th

Preparation according to the invention of a composite profile from an initial profile cross-section according to FIG. 1 proceeds according to the 10 manufacturing steps below: First, the two metal profiles 2, 3 are extruded as a pro-file unit in one piece and pre-treated in the usual manner (for example, electrical oxidation). In a subsequent step of the method (Fig. 2), the gutter 20, which is laterally delimited by the inner walls 19 of the metal profiles 2, 3, and which is delimited downwardly by the cohesive joint 9, is filled by means of a casting head 25 with a commercially available thermoplastic resin 21 as insulating molding material 20, whereby the bonding flange 9 simultaneously acts as the bottom of the gutter 20. When the plastic barrel is hardened and stiffened to the insulation core strip 5, a part of the width of the bonding flange 9 is removed between the metal profiles 2, 3 for example with a saw 22, a milling machine or the like (fig.

25 3). Then rotate the profile 180 ° around its longitudinal axis (Fig. 4). The position of the profile after turning is shown in fig.

5. Then the separating strip 8 is inserted between the metal profiles (Fig. 6) so that it is spaced apart in the high direction of the cavity 7 on the support edges 23 on the sides of the meta profiles, and has the task of forming a bottom in another gutter 24. 1 a final step of the method, the gutter 24 is molded through a casting head 29 with the plastic material 2i. After its nourishment, the second insulation core strip 5 is formed and the composite profile is prepared for further processing.

n DK 157040 B

The method of producing the initial profile cross-section according to FIG. 1 is used in a similar manner to produce the other composite profiles shown.

5

At the output profile cross-section according to FIG. 8, the two bonding flanges 10, 11 arranged one above the other are removed by means of the saw 22 shown in dotted lines in one working step, that is, the two bonding flanges 10 are separated simultaneously or almost simultaneously. Of course, the separation can take place in other ways, for example by cutting, tearing, etc.

In the manufacture of composite profiles having more than two side-by-side metal profiles as shown in FIG. 9, both renderings are filled simultaneously with the resin 21.

For this purpose, instead of the one shown in FIG. 2 used one casting head 25, two side-by-side, parallel-mounted casting heads 25. Similarly, in these profiles the adjacent flanges 12, 13 and 12, 14, 13, 15, respectively, are removed in FIG. . 10 after forming the insulation core moldings 6 ', 6' 'simultaneously by means of parallel arranged saws 25 22. In principle, for composite profiles with two or more insulation zones A and B, one should assume that all work steps are taken, such as casting of grids, removal of tie-down flanges, insertion of dividers, must be possible at the same time during the production process.

30

Preparation of the composite profile according to FIG. 12 from the starting profile cross section according to FIG. 11 is by the same procedure as described with reference to FIG. 1-7 with the only difference being that after the insulation core list

12 DK 157040 B

18 is formed in the first molded gutter and after the bonding flanges 10, 11 are removed and the profile is reversed, two rows are cast one after the other with plastic 16, 17 instead of one gutter after separating moldings 8 ' 8 '* are placed on the support edges 23' as the bottom of the gutters 24 'and 24 before the casting step.

In FIG. 14-22, a manufacturing process is shown in which, in contrast to the described method of manufacture, a composite profile with three insulation core strips corresponding to FIG.

12 does not cast two rows of plastic material after the reversal of the mecal profile, but only one gutter, while the other two insulation core moldings are manufactured for the reversal. The preparation of FIG. 13 should emphasize that, as a result of the extruder technique, in principle all possible cross sections may be provided with a bonding flange II '' which closes the profile on at least one outer surface and which must therefore be removed before the start of the casting step. Assuming the starting cross section thus prepared according to fig.

20 14, the first gutter 76 is first cast from the mold head 25 with resin 21 to form the insulation core core 17 '(Fig. 15). Then, a dividing strip 8, i: 5 (Fig. 16) is placed on the supporting edges 23 above, and the

The gutter 77 thus formed is filled with plastic from the mold head 25 '(Fig. 17). Then, the bonding flanges 10 ', 11' are separated by the saw 22 (Fig. 13), the profile is turned (Figs. 19, 20), and the last gutter 78 is formed by placing a dividing strip 8 (Fig. 21) in place and there I

filled with plastic from a casting head 29 (Fig. 22).

In FIG. 23 is a schematic representation of a composite profile according to FIG. 7. The first molding head for filling! of the upper gutter in each of the profiles 2, 3 is denoted! thereby by 25, the feeding direction behind the saw 22 | i i i j 13

5 Compared to the one shown in FIG. 23, FIG.

24 is an alternative variant which differs from the former in that the composite profile 2, 3 after turning at the turning station 27 is transferred from the first transport direction 26 by parallel displacement in the direction of arrow 30 to another transport path where the profile is transported. opposite the feeding direction 26 in the direction of arrow 31 in the direction of the device 28 for the loading of the dividing strip and the second casting head 29. In this method, the profile can simultaneously be turned and transferred to the other, parallel to the first 10-open conveying path, the torque is done by hand or by means of a suitable twisting device (not shown), and the transverse transport of the profile in the direction of the arrow 30 is effected by a driven conveyor belt 33 resting on rollers 32. This variant of the 20 method is used in practice. preferably, the length of the factory hall available does not correspond to a rectilinear production process similar to FIG.

25 The device for producing a composite profile according to FIG. 27, which is identical to that of FIG. 7 shows a horizontally arranged work table 34 (Figs. 25, 26), which rests on the floor of foot 35. The work table 34, which may also consist of another optional support 30 device and can also be divided into several tables (fig.

23), has a support surface for the metal profiles 2, 3 which, during machining to composite profiles 1, is transported on the predetermined transport path in the direction of arrow 26 between rollers 36, 37. The rollers 36, 37 are arranged in

DK 157040 B

14 the workbench 34 on vertical shafts 36 ', 37'. The rollers 36 on one side of the table are pivotally secured to the shafts 36 'and driven by them, while the rollers 37 arranged on the other side lack drive and serve only 5 as a support for the metal profiles 2, 3 which are pulled by friction of the driven rollers 36. The rollers 36 are driven by a motor 38, the gear drive 39 of which over a gear 40 drives a shaft 41. This longitudinally and with the distance of the rollers 36, tapered gears 42 which are in engagement with corresponding tapered gears 43. These are wedged onto the shaft pins 36 'which project under the workbench 34 and transmit the engine propulsion movement to the rollers 36.

15 Above the workbench 34 there is a first molding device 25 consisting of a molding head 25 'and a feeding nozzle 25' '. The casting head 25 is connected via a conduit 44 in conjunction with a casting resin supply container 45 and is adjustably suspended in a holding device 46 secured to the workbench 34. The casting material consists of known casting resins which are advanced in liquid form through the casting device 25 25 'and solidifies after a short curing time. The casting material is fed by a pump not shown. From mold head 25 ', resin 25 21 is obtained according to the method of FIG. 2 into the upper gutter of the profile.

At a distance behind the first molding device 25 is a circular blade metal saw 22, which is wedged 30 on a shaft 47 and driven by a motor 47 'mounted on the table 34 (Fig. 29). It is recommended that the saw 22 be suspended so that the height can be adjusted according to the double arrow 48. The saw blade 22 is so narrow that it has sufficient clearance in the cavity 7 (Fig. 3) between the profiles 2, 3, and

DK 157040B

so that it can unobstructed and continuously remove the metallic bonding flange 9 from the underside of the profile during transport of the profile in the direction of the arrow 26. The roller 75, which is suspended in the frame 72, 73 via a rotatable spindle 5 74 (Fig. 29), serves to control the composite profile in a vertical direction, in particular to absorb the counterpressure while removing the bonding flanges.

Immediately after the end 49 of the composite profile 2, 3 rear 10 has passed the saw 22, the composite profile is at the turning station 27, the length of which is neither transport rollers 36 nor the corresponding rollers 37 so that the profile can be rotated around its longitudinal axis from the one shown in FIG. 4 to the position in FIG. 5 by hand by means of a suitable rotary device (not shown).

Directly behind the front end 50 of the metal profile and outside the turning station 27, there is a supply roller 51 for the dividing strip 8 which, during the displacement movement of the composite profile, is continuously fed into the calculated space in the gutter 24. The spacer above the gutter 24 is arranged. roll 51 is disposed on an axis 52 extending transversely of the conveying direction 26 and which is freely suspended 25 pivotally in bearings 53, 54 carried by the work table 34 over carriers 55.

Behind the separator stock roll 51 there is a separator guide device 56 which, by means of guide rollers 57, 30 58 and a convex vaulted baffle 59, temporarily bends the dividing strips 8 in the transverse direction to make it easier to place them on the support edges 23 of the gutter 24.

In the transport direction 26 behind the separator stock roll 16

DK 157040 B

51 and the separator guide device 56, there is furthermore a pressure roller 61 arranged freely pivotally on a pivot arm 60, which has the task of pressing the separating strips 8 against the supporting edges 23 of the intermediate bottoms in the gutter so that one can be obtained uniform and close contact between moldings 8 and support edges as possible. The pivot arm 60 is provided with the end facing away from the pressure roller 61 on a shaft 62, the two ends of which are supported by bearing shells 63 which are secured to the workbench 34. By the supporting means 64, in order to exert the necessary pressure on the separating strip 8, the swing arm is spring- or weight-loaded.

In the transport direction 26 behind the dividing strip supply roll 51, the second molding device 29 is arranged. It is constructed 15 in the same manner as the first molding device 25 and similarly has a casting head 66, a feeding nozzle 67, a connecting conduit 68, a molding supply container 69 and a holding device 70.

The mold 21 is fed from the mold head into the gutter 24.

The metal profiles 2, 3, which in the manner described are filled with molding material, are further transported at unchanged feeding rate on the workbench 34 after they have fit the last molding device 29. When also the molding material in the last filled tube 24 is stiffened when the first metal profile length 50 is a separation device consisting of an extension 34 'of the workbench 34 and the supporting surface of which is angled relative to the workbench. Hereby 30 is obtained that the front metal profile 2 ', 3' at its own weight and as a result of non-supporting support bends downward at this point and breaks at its weakest point, which is where the rear end of the front metal profile 2 ', 3' 49 'and the front end 50 of the immediately behind the metal profile.

17 DK 15 7 04 0 B

Files 2, 3 lie together and in this way are separated from the subsequent profile length. Since the only connection between the two profile lengths consists of the intermediate stiffening insulating cores 5, 6 and the continuous separating list 5, the cracking and breaking point respectively are in the insulating cores and the separating strip.

It is, of course, also possible, instead of with the described separation device, to separate the contiguous profile lengths with one in FIG. 25 by a punctured union indicated, suitable saw 70, which may then be suitably arranged to be able to work perpendicular to the direction of transport (pii 71) in order to operate without interruption of the transport. You can also think of manual separation 15 or mechanically by means of scissors, knife or the like.

For the preparation of a profile according to FIG. 22, only one additional separator supply roll 51 is required and, at a distance therefrom, a further casting device 25 '' 'is located behind the first first casting device 25 in the embodiment shown in FIG. 25 shown in transport direction 26. This arrangement is shown schematically in FIG. 34th

For the preparation of the composite profile according to FIG. 12, 25 whereby first the insulating cores 18 are formed, and then turning and inserting the separating strip 8 'into the gutter 24' of the insulating cores 17 requires that, after casting 29 in the system according to FIG. 25 connects a separator supply roll 51 '' to introduce the separating strips 8 '' 30 and a further molding device 29 'to the insulating core 6 so as to cast the gutter 24 to be molded eventually (Fig. 35).
