Description
DK 155376 BDK 155376 B
Opfindelsen angår en fremgangsmåde til fremstilling af et varmeisolerende profil til rammer til døre, vinduer eller facadeelementer, hvor et strengpresset, med et gennemgå-5 ende hulrum forsynet rammeprofil af metal, navnlig letmetal, fremstilles i et stykke, og hvor hulrummet fyldes med et flydende, hærdbart skumstof eller en støbeharpiks under dannelse af et isoleringslegeme, hvorefter på profilets side placerede profilvægstrimler afrives under 10 dannelse af to med indbyrdes afstand placerede og alene ved isoleringslegemet sammenholdte rammeprofilhalvdele.The invention relates to a method for producing a heat insulating profile for frames for doors, windows or facade elements, in which a extruded, metal-framed frame profile, in particular light metal, is manufactured in one piece and the cavity is filled with a liquid. , curable foam or a casting resin to form an insulating body, after which profile wall strips placed on the profile are stripped during formation of two spaced apart spacer halves at the insulating body alone.
Fra DE-patentskrifter nr. 1.174.483, nr. 2.033.442 og DE-fremlæggelsesskrift nr. 1.245.567 kendes fremgangsmåder til fremstilling af varmeisolerende profiler, hvor 15 hæfteforbindelsen mellem de to rammeprofilhalvdele og de derimellem liggende isoleringslegemer i mange tilfælde ikke er tilstrækkeligt, hvorved der opstår det problem, at forskydningsstyrken skal forøges væsentligt.DE Patent Specifications No. 1,174,483, No. 2,033,442, and German Patent Specification No. 1,245,567 disclose methods for producing heat insulating profiles, where the adhesive connection between the two frame profile halves and the insulating bodies therein is in many cases insufficient , thereby causing the problem that the shear strength must be significantly increased.
Opfindelsen har til formål at anvise en fremgangsmåde af 20 den indledningsvis nævnte art, hvor de i overensstemmelse med opfindelsen fremstillede profiler under opretholdelse af formstabilitet og tolerancenøjagtighed opnås en væsentlig forbedret hæfteforbindelse mellem de to rammeprofilhalvdele og isoleringslegemet.It is an object of the invention to provide a method of the type mentioned in the first, wherein the profiles prepared in accordance with the invention, while maintaining mold stability and tolerance accuracy, obtain a significantly improved adhesive connection between the two frame profile halves and the insulating body.
25 Dette formål opnås ifølge opfindelsen derved, at ribber på indersiden af rammeprofilets hulrum bibringes diskontinuiteter i form af på tværs eller skråt forløbende udsparinger i ribben ved en særskilt operation forud for skumstoffets indfyldning i hulrummet. 1This object is achieved according to the invention in that ribs on the inside of the cavity of the frame profile are imparted to discontinuities in the form of transverse or oblique recesses in the rib by a separate operation prior to the filling of the foam into the cavity. 1
Disse diskontinuiteter, der ifølge opfindelsen allerede er tilvejebragt, før formstoffet fyldes i rammeprofilet, udfyldes af formstoffet. Det er herefter ikke nødvendigt at påføre yderligere deformeringskræfter på rammeprofilet.These discontinuities, which according to the invention have already been provided before the plastic material is filled into the frame profile, are filled in by the plastic material. It is then not necessary to apply additional deformation forces to the frame profile.
Som følge af isoleringslegemets fortanding ind i rammepro-As a result of the insulation of the insulating body into the frame project.

2 filhalvdelene opnås der, uden at formstoffet deformeres på kærvømfindtlig måde, en særlig stor forskydningsstyrke ved det varmeisolerede profil.In the two halves of the file, a particularly high shear strength is obtained by the heat insulated profile, without deforming the fabric in a spring-sensitive manner.
5 Fra DE-offentliggførelsesskrift nr. 2.558.450 kendes der ganske vist en metalhulprofilstang, som udvendigt er omgivet af et formstoflag, og hvor metalhulprofilstangens yderflade er forsynet med tværprofileringer for at forbedre forskydningsstyrken mellem metal og formstof.5 DE-publication specification 2,558,450 discloses a metal hollow profile bar which is externally surrounded by a plastic layer, and the outer surface of the metal hollow profile bar is provided with cross-profiles to improve the shear strength between metal and plastic.
10 Tværbindeelementer på metalhulprofilstangens indersider er ikke forsynet med udsparinger.10 Cross-link elements on the inside of the metal hollow profile bar are not provided with recesses.
Til dannelse af udsparinger er det i henhold til opfindelsen tillige muligt, at føre et værktøj gennem rammeprofilets hulrum på samme måde som en gevindsnittap ved en 15 relativ bevægelse i forhold til rammeprofilet. Det er ved denne fremgangsmåde således muligt både at bevæge gevindsnittappen gennem det stationære rammeprofil og omvendt at holde snittappen stationær, men drejelig og at bevæge rammeprofilet.In order to form recesses, according to the invention, it is also possible to pass a tool through the cavity of the frame profile in the same way as a thread cut in a relative motion relative to the frame profile. Thus, in this method, it is possible to move both the thread cutter pin through the stationary frame profile and vice versa to keep the cutter pin stationary but rotatable and to move the frame profile.
20 Samtlige de forannævnte foranstaltninger til dannelse af udsparinger betinger imidlertid en yderligere arbejdsoperation.20 However, all the aforementioned measures to generate recesses require a further work operation.
Opfindelsen giver også mulighed for at tilvejebringe udsparingerne uden en sådan yderligere arbejdsgang. Dette 25 kan ifølge opfindelsen opnås derved, at der ved strengpresning af rammeprofilet sker en af drejning af den til dannelse af tværbindeelementerne bestemte materialestrøm-~ ning fra strengpresseretningen under en sådan vinkel, at hvert tværbindeelement rives op efter passagen af streng-30 presseværktøjet under dannelse af udsparingerne samt på tværs af længderetningen af rammeprofilet forløbende korte tværbindeelementer. Til udøvelse af fremgangsmåden er det hensigtmæssigt at anvende et strengpresseværktøj, hvor der til formgivning af rammeprofilets hulrum er tilvejebragt 3The invention also provides the opportunity to provide the recesses without such additional workflow. This can be achieved in accordance with the invention in that, when the frame profile is extruded, a flow of material determined to form the crosslinking elements from the stringing direction at an angle is rotated at such an angle that each crosslinking element is torn up after the passage of the stringing press tool during formation. of the recesses as well as short cross-linking elements extending transverse to the longitudinal direction of the frame profile. In order to carry out the method, it is convenient to use an extruder tool which provides for forming the cavity of the frame profile 3

en dorn, hvis udvendige flader er forsynet med rendelig-nende fordybninger til dannelse af tværbindeelementerne.a mandrel whose outer surfaces are provided with cleanable recesses to form the crosslinking members.
Til dette formål er de rendelignende fordybninger anbragt 5 under en spids vinkel med presseretningen, f.eks. i størrelsesordenen 5°.For this purpose, the gutter-like recesses are arranged at an acute angle with the pressing direction, e.g. in the order of 5 °.
I praksis har det vist sig, at den skrå placering af de rendelignende fordybninger fører til en kontinuerlig gennembrydning af de derved dannede forbindelseselementer.In practice, it has been found that the oblique location of the gutter-like recesses leads to a continuous breakthrough of the connecting elements thus formed.
10 Medens hovedbestanddelen af strengpressemassen udfører den sædvanlige bevægelse i strengpresseretningen gennem strengpresseværktøjet, vil en lille del af massen, som føres gennem de rendeformede fordybninger, rettes bort fra denne retning. Dette medfører uvægerligt deformationer af 15 de ved fordybningerne dannede, ribbelignende forbindelseselementer.While the main component of the extruder mass performs the usual movement in the extruder direction through the extruder tool, a small portion of the mass passing through the gutter grooves will be directed away from this direction. This inevitably causes deformations of the rib-like connecting elements formed by the recesses.
Opfindelsen vil i det følgende blive nærmere forklaret i forbindelse med nogle udførelseseksempler og under henvisning til tegningen, hvor 20 fig. 1 viser et tværsnit gennem et i ét stykke udformet hulprofil med deformerbare ribber, fig. 2 et længdesnit gennem det i fig. 1 viste hulprofil med et værktøj til deformering af ribberne, fig. 3 et tværsnit gennem et med tværribber forsynet hul-25 profil til anbringelse af skruegevindformede underskæringer, fig. 4 et tværsnit gennem et strengpresseværktøj, fig. 5 den i fig. 4 viste strengpresseværktøjsdorn, set fra siden i retning af pilen A, 1 fig. 6 et længdesnit gennem et med strengpresseværktøjetThe invention will be explained in more detail below with reference to some embodiments and with reference to the drawing, in which: FIG. 1 shows a cross-section through a one-piece hollow profile with deformable ribs; FIG. 2 is a longitudinal section through the embodiment of FIG. 1 shows a hollow profile with a tool for deforming the ribs; FIG. 3 is a cross-sectional view through a hollow-cut hollow profile for the application of screw threaded cuts; FIG. 4 is a cross-section through an extruder; FIG. 5 is the one shown in FIG. 4 is a side view of the extruder tool mandrel shown in the direction of arrow A; FIG. 6 is a longitudinal section through one with the extruder tool

4 i fig. 4 fremstillet hulprofil taget langs et snit svarende til det i fig. 4 viste snit VI-VI, fig. 7 perspektivisk en detalje af et strengpresseprofil 5 med en ribbe, bølgeformet udformet ved hjælp af en excentrisk lejret deformeringsvalse, fig. 8 en dorn i et strengpresseværktøj med den derpå lejrede deformeringsvalse, set fra oven.4 in FIG. 4 shows a hollow profile taken along a section similar to that of FIG. 4, FIG. 7 is a perspective view of a strand press profile 5 having a rib, corrugated, formed by an eccentrically mounted deformation roller; FIG. 8 is a top view of a mandrel in an extruder with the deforming roller mounted thereon.
I det i fig. 1 viste udførelseseksempel ses i ét stykke 10 udformet hulprofil 1 af letmetal, hvor de to rammehalvpar-ter 2,3 via afrivelige vægstrimler 5 omslutter et hulrum 4, hvori formstof i flydende tilstand indfyldes til størkning eller opskumning. Ved afrivning af vægstrimlerne efter formstoffets afhærdning opstår et varmeisolerende 15 stangprofil.In the embodiment of FIG. 1, a hollow profile 1 is made of light metal, in which the two frame halves 2,3, via peelable wall strips 5, enclose a cavity 4, in which liquid material is filled for solidification or foaming. Upon tearing off the wall strips after the curing of the fabric, a heat-insulating rod profile is formed.
Inderfladerne i rammehalvparterne 2,3 er nu forsynet med ribber 7, der forløber i stangprofilets længderetning og kan fremstilles ved strengpresningen uden besvær. Disse ribber 7 er fortrinsvis af V-form. Ribberne 7 skal derfor 20 forsynes med underskæringer eller udsparinger, som forløber på tværs af stangprofilets længdeakse. Der opnås nemlig en særlig, mod forskydning bestandig forbindelse mellem rammehalvparterne 2,3 og isoleringslegemet, når formstoffet trænger ind i disse underskæringer eller ud-25 sparinger.The inner surfaces of the frame hemispheres 2,3 are now provided with ribs 7 which extend in the longitudinal direction of the rod profile and can be manufactured by the string pressing without difficulty. These ribs 7 are preferably V-shaped. The ribs 7 must therefore be provided with cuts or recesses extending across the longitudinal axis of the rod profile. Namely, a special, shear-resistant connection is obtained between the frame halves 2,3 and the insulating body when the plastic material penetrates these cuts or recesses.
Disse udsparinger fremstilles som vist i fig. 2 ved hjælp af et særligt deformeringsværktøj 8, som i pilen 14's retning trækkes eller skubbes gennem det i ét stykke udformede hulprofil 1. Dette deformeringsværktøj 8 har f.eks.These recesses are made as shown in FIG. 2 by means of a special deformation tool 8 which in the direction of arrow 14 is drawn or pushed through the one-piece hollow profile 1. This deformation tool 8 has e.g.

5 profilering 13. Det kan anbefales at udforme rullen 9's lejring til under bestemte belastninger at kunne vige for at undgå klemninger. Rullen 9 kan også være styret drevet, 5 f.eks. ved at blive ført langs en tandstang. Ækvivalente udførelsesformer vil f.eks. være sådanne værktøjer, der også frembringer underskæringer 13 uden derved at rotere.5 profiling 13. It is advisable to design the bearing 9 of the roller 9 to be able to fold under certain loads to avoid clamps. The roller 9 may also be guided driven, e.g. by being led along a toothpick. Equivalent embodiments will e.g. be such tools that also produce undercuts 13 without thereby rotating.
Dette kan f.eks. ske ved stedvis udspiling af et passende udformet værktøj.This can be done, for example. This is done by means of a randomly designed tool.
10 I det i fig. 3 viste eksempel ses et hulprofil 1, som i modsætning til det i fig. 1 viste profil har indadrettede tværribber 11, for at hulrummene 4 kan blive forsynet med underskæringer eller udsparinger. Der kan nu igennem et sådant hulprofil 1 føres en gevindtap 12, eller profilet 1 15 kan langs en stationær, men drejeligt lejret gevindtap forskydes på en sådan måde, at gevindtappens skærende ægge skærer sig ind i tværribberne 11's kanter. Derved dannes et skruegevind, som ligeledes frembringer en fremragende forskydningsstyrke mellem hulprofilet 1 og den deri 20 indfyldte formstofkerne.10 In the embodiment of FIG. 3 shows a hollow profile 1 which, unlike the one shown in FIG. 1 has inwardly facing transverse ribs 11 so that the cavities 4 can be provided with cuts or recesses. A threaded pin 12 can now be passed through such a hollow profile 1, or the profile 1 15 can be displaced along a stationary but pivotally mounted threaded pin in such a way that the cutting edge of the threaded pin cuts into the edges of the cross-ribs 11. Thereby, a screw thread is formed which also produces an excellent shear strength between the hollow profile 1 and the plastic core filled therein.
I det i fig. 4 til 6 viste eksempel vises en fremgangsmåde, ved hjælp af hvilken underskæringerne 13 uden en ekstra arbejdsoperation kan opnås. Fig. 4 viser skematisk tværsnittet gennem et strengpresseværktøj 15, som bestem-25 mer hulprofilet l's yderkontur. Inde i strengpresseværktøjet 15, således som det er almindeligt ved fremstilling af hulprofiler, er anbragt en dorn 16, som bestemmer hulprofilet l’s inderkontur. Det plastiske materiale presses igennem det mellem strengpresseværktøjet 15 og dornen 16 30 værende hulrum. Dette hulrum svarer da til det hulprofil, der skal fremstilles.In the embodiment of FIG. Examples 4 to 6 show a method by which the undercuts 13 can be obtained without an additional working operation. FIG. 4 schematically shows the cross-section through an extruder tool 15 which determines the outer contour of the hollow profile 1. Inside the extruder tool 15, as is common in the manufacture of hollow profiles, is provided a mandrel 16 which determines the inner contour of the hollow profile 1. The plastic material is pressed through the cavity between the extruder tool 15 and the mandrel 16 30. This cavity then corresponds to the hole profile to be manufactured.
Dornen 16 har nu på sine sideflader rendeformede, fortrinsvis med kileprofil udformede fordybninger 17, der følgeligt i det hulprofil, der skal fremstilles, bevirker 35 langsgående og ophøjede ribber af kileformet tværsnit.The mandrel 16 now has groove-shaped, preferably wedge-shaped recesses 17 on its lateral surfaces, which, consequently in the hollow profile to be manufactured, cause 35 longitudinal and raised ribs of wedge-shaped cross-section.

I fald de rendeagtige fordybninger 17, som dornen 16’s sidebillede viser i fig. 5, ikke anbringes parallelt med strengpresseretningen 18, men snarere danner en spids 5 vinkel med denne, bliver den pågældende del af strengpressematerialet, som fremføres i disse rendeagtige fordybninger 17's område, afbøjet fra den normale strengpresseret-ning. Eftersom imidlertid det tilstødende materiale, hvoraf pofilet l's ribbevægge dannes, fremføres i streng-10 presseretningen 18, opstår der under strengpresningen en usikker forbindelse mellem det i fordybningerne 17 fremførte materiale og det øvrige strengpressemateriale. Dette bevirker, at de i profilet dannede ribber 19, som det fremgår af fig. 6, bibringes en savtandagtig profilering, 15 eftersom disse ribber 19's materiale, som følge af de rendeagtige fordybninger 17's skråstilling i dornen 16, til stadighed afbrydes. Følgelig opstår der mellem de tilbageblevne ribbedele 19 mellemrum eller afbrydelser, som har samme funktion som den underskårne eller med udsparin-20 ger forsynede profilering 13. I praksis har det vist sig, at samvirkningen mellem hulprofilet og isoleringslegemet i dette udførelseseksempel er særlig høj. Det har endvidere i praksis vist sig fordelagtigt med en vinkelstilling på eksempelvis 5° for de rendeagtige fordybninger 17 i for-25 hold til strengpresseretningen 18 til opnåelse af nævnte virkning. Der er dog ingen tvivl om, at andre vinkelstørrelser, udformninger eller lignende også er egnet til opnåelse af dette formål.In case of the gutter-like recesses 17, which the side view of the mandrel 16 shows in fig. 5, is not placed parallel to the extruder direction 18, but rather forms an acute angle 5 thereto, the relevant portion of the extruder material conveyed in the region of these gutter recesses 17 is deflected from the normal extruder direction. However, since the adjacent material from which the rib walls of the profile 1 are formed is fed in the string pressing direction 18, during the string pressing, an uncertain connection occurs between the material advanced in the recesses 17 and the other string pressing material. This causes the ribs 19 formed in the profile as shown in FIG. 6, a tooth-like profiling is imparted 15 as the material of these ribs 19, due to the inclined position of the gutter-shaped recesses 17 in the mandrel 16, is constantly interrupted. Accordingly, between the remaining rib portions 19 are interrupted or interrupted which have the same function as the undercut or recessed profiling 13. In practice, it has been found that the interaction between the hollow profile and the insulating body in this embodiment is particularly high. In practice, it has also proved advantageous with an angular position of, for example, 5 ° for the gutter recesses 17 in relation to the extruder direction 18 to achieve said effect. However, there is no doubt that other angular sizes, designs or the like are also suitable for this purpose.
Det i fig. 7 og 8 viste udførelseseksempel viser nu, hvor-30 ledes et metalprofil l's indvendige ribbe 20 kan deformeres bølgeformet under frempresningen eller ekstruderingen uafhængigt af, om dette sker i forbindelse med et lukket eller halvåbent hulprofil eller ved en U-formet rammehalvpart, hvorhos denne deformation kan foregå både 35 indvendigt og udvendigt.The FIG. Examples 7 and 8 now show how the inner rib 20 of a metal profile 1 can be deformed corrugated during the pressing or extrusion regardless of whether this occurs in connection with a closed or semi-open hole profile or a U-shaped frame half, where this deformation can take place both inside and outside.

Den i fig. 7 viste ribbe 20 rager i dette udførelseseksempel ind i metalprofilet l's inderrum, som senere skal udfyldes med skumstof. Ved sin frie ende har ribben 20 en 5 i tværsnit cirkulær, langsgående profilering 21, som senere indesluttes af det opskummede formstof. På det i fig. 7 ikke viste strengpresseværktøj er en deformeringsvalse 22 drejeligt lejret om en excentrisk beliggende akse 23, og def ormeringsvalsen 22 er på sin omkredsflade 24 10 forsynet med en fortanding, rifling eller lignende profilering. Med denne omkredsflade 24 indvirker deformeringsvalsen eller -rullen 22 periodisk mod den endnu af strengpresningen plastisk deformerbare ribbe 20, hvilket bevirker en bølgeformet profilering 25 af denne ribbe 20.The FIG. 7, in this embodiment, the rib 20 shown protrudes into the inner space of the metal profile 1, which is later to be filled with foam. At its free end, the rib 20 has a 5 cross-sectional circular longitudinal profiling 21, which is later enclosed by the foamed plastic. In the embodiment of FIG. 7, the deformation roller 22 is pivotally mounted about an eccentrically located axis 23, and the deformation roller 22 is provided on its circumferential surface 24 10 with a tooth, groove or similar profiling. With this circumferential surface 24, the deformation roller or roller 22 interacts periodically with the deformable rib 20, which is still plastically deformable, which causes a corrugated profiling 25 of this rib 20.
15 I fig. 8 ses en detalje af en strengpressematrices dorn 26, set fra oven, hvor deformeringsvalsen 22 er excentrisk lejret ved strengpressematricens eller ekstruderingshove-dets i strengpresseretningen 27 udgående side. En strengpressematrices dorn bestemmer et hulprofils indre 20 tværsnit.In FIG. 8, a detail of the mandrel 26 of an extruder die is seen from above, where the deformation roller 22 is eccentrically mounted at the side of the extruder die or extrusion head in the extruder direction 27. The mandrel of an extruder die determines the inner cross section of a hollow profile.
