Description
Den foreliggende oppfinnelse vedrører en fremgangsmåte for fremstilling av en komposittkomponent i henhold til innledningen i patentkrav 1 såvel som en anordning for gjennomføring av fremgangsmåten samt anvendelsen av en komposittkomponent. The present invention relates to a method for producing a composite component according to the introduction in patent claim 1 as well as a device for carrying out the method and the use of a composite component.
JP-OS 1-275831 A beskriver fremstilling av en aluminiumkomposittkomponent: Fra en aluminiumskumblokk kappes tynne aluminiumskumskiver, og klebes til en aluminiumplate i en stor flate. JP-OS 1-275831 A describes the production of an aluminum composite component: Thin aluminum foam discs are cut from an aluminum foam block and glued to an aluminum plate in a large area.
Den kjente fremgangsmåten for fremstilling av en komposittkomponent av denne type er svært omstendelig: I et første trinn fremstilles en aluminiumskumblokk, av hvilken det kappes plane aluminiumskiver i et andre trinn. I et tredje trinn blir disse skivene klebet sammen med aluminiumplaten. Da klebeoverflatene av aluminiumskumskivene pga skjæreforløpet oppviser åpne porer, er betydelige mengder klebemiddel nødvendig, noe som bidrar til en vektøkning for komposittkomponenten. Dessuten egner den beskrevne fremgangsmåten seg kun til fremstilling av plane komposittkomponenter. The known method for producing a composite component of this type is very cumbersome: In a first step, an aluminum foam block is produced, from which planar aluminum discs are cut in a second step. In a third step, these discs are glued together with the aluminum plate. As the adhesive surfaces of the aluminum foam discs exhibit open pores due to the cutting process, significant amounts of adhesive are required, which contributes to an increase in weight for the composite component. Moreover, the described method is only suitable for the production of planar composite components.
Oppfinnelsens oppgave er derfor å tilveiebringe en fremgangsmåte og en anordning for en enkel, rask og kostnadsgunstig fremstilling av en komposittkomponent, slik at ulempene ved den kjente teknikken kan unngås. The task of the invention is therefore to provide a method and a device for a simple, fast and cost-effective production of a composite component, so that the disadvantages of the known technique can be avoided.
Denne oppgaven løses ved de karakteriserende trekk i krav 1. Krav 9-10 angår en anordning i henhold til oppfinnelsen, for gjennomføring av fremgangsmåten. This task is solved by the characterizing features in claim 1. Claims 9-10 relate to a device according to the invention, for carrying out the method.
Oppfinnelsens hovedidé er å opprette binding mellom metallplate og metallskum i form av en diffusjonsbinding, hvori varmt, ikke forhåndsformet metallskum blir påført direkte på metallplaten. Herved muliggjøres det umiddelbart å koble fremstillingen av komposittkomponenten til fremstillingen av metallskum. Dermed blir ikke først en metallskumblokk fremstilt, som etter sin avkjøling kappes i metallskumskiver og som må klebes til metallplaten i et særskilt arbeidstrinn. Derimot skjer skumfremstilling og fremstilling av komposittkomponenten skjer umiddelbart etter hverandre. Herved har man en enkel og økonomisk fremgangsmåte til disposisjon som komposittkomponenter av denne typen kan bli fremstilt ved uten bruk av klebemiddel. The main idea of the invention is to create a bond between metal sheet and metal foam in the form of a diffusion bond, in which hot, non-preformed metal foam is applied directly to the metal sheet. This makes it possible to immediately link the production of the composite component to the production of metal foam. Thus, a metal foam block is not first produced, which after cooling is cut into metal foam discs and which must be glued to the metal plate in a separate work step. In contrast, foam production and production of the composite component take place immediately after each other. Hereby, a simple and economical method is available by which composite components of this type can be produced without the use of adhesives.
Metallskummet befinner seg i henhold til oppfinnelsen i en ennå formbar tilstand, foretrukket i en flytende smeltetilstand. Også halvfast metallskum kan bearbeides. Med "metall..." forstås det i oppfinnelsens sammenheng en metall-legering med viskositetsøkende komponenter som tjener til stabilisering av den flytende smelteskumstrukturen. According to the invention, the metal foam is in a still malleable state, preferably in a liquid molten state. Semi-solid metal foam can also be processed. In the context of the invention, "metal..." means a metal alloy with viscosity-increasing components that serve to stabilize the liquid melt foam structure.
Metallplatene i henhold til oppfinnelsen er ikke nødvendigvis plane, men kan i sin dimensjon være utformet innen vide grenser og i hvilken som helst form, slik tilfellet er ved f.eks. dyptrekking av forhåndsformede metalliske karosserikomponenter. The metal plates according to the invention are not necessarily flat, but can be designed in their dimensions within wide limits and in any shape, as is the case with e.g. deep drawing of preformed metallic body components.
Utførelsen av oppfinnelsen i henhold til krav 2 gir en sikker binding som tåler belastning mellom metallskum og metallplate, idet det ved forvarmingen av metallplaten unngås avkjøling som er hemmende for diffusjonsbinding av metallskummet på kontaktflaten med metallplaten. The embodiment of the invention according to claim 2 provides a secure bond that withstands stress between the metal foam and the metal plate, as the preheating of the metal plate avoids cooling which inhibits diffusion bonding of the metal foam on the contact surface with the metal plate.
Også utførelsen av oppfinnelsen i henhold til krav 3 gir en forutsetning for en forbindelse mellom komponentene. Det tilsatte geleringsmiddel setter ned overflatespenningen og medfører under visse omstendigheter også en løsgjøring av metallplateoverflaten. The implementation of the invention according to claim 3 also provides a prerequisite for a connection between the components. The added gelling agent lowers the surface tension and, under certain circumstances, also causes a loosening of the sheet metal surface.
Med utførelsen av oppfinnelsen i henhold til krav 4 er det oppnådd en meget anvendelig fremstillingsmetode, som på en kostnadsgunstig måte muliggjør automatisert serieproduksjon av komposittkomponenter. Herved blir metallskummet i en kontinuerlig prosess tilført en kant av metallplaten, som f.eks. kan være utført som en endeløs metallplate, hvorved en innlegging og uttak av enkeltvise metallplater bortfaller. With the implementation of the invention according to claim 4, a very applicable production method has been achieved, which enables automated serial production of composite components in a cost-effective manner. In this way, the metal foam is added in a continuous process to an edge of the metal plate, which e.g. can be made as an endless metal plate, whereby inserting and removing individual metal plates is eliminated.
Skumfremstillingen kan herved f.eks. skje ifølge fremgangsmåten beskrevet i US 4.973.358. The foam production can e.g. take place according to the method described in US 4,973,358.
Med utførelsen i henhold til krav 5 er det mulig på en enkel måte å innstille tykkelsen av metallskumsjiktet individuelt, hvorved reguleringsinnretningen sørger for en konstant tykkelse og en glattet overflate. With the design according to claim 5, it is possible in a simple way to set the thickness of the metal foam layer individually, whereby the regulation device ensures a constant thickness and a smooth surface.
Oppvarmingen av reguleringsinnretningen i henhold til krav 6 letter fremstillingen av en plan overflate på metallskumsjiktet. Alt etter temperatur og utforming av reguleringsinnretningen er det mulig å oppnå en lukket metallskumoverflate. Dermed kan den ferdige komposittkomponenten også rengjøres på metallskumsiden på en enkel måte eller utstyres med andre komponenter. The heating of the regulation device according to claim 6 facilitates the production of a flat surface on the metal foam layer. Depending on the temperature and design of the control device, it is possible to achieve a closed metal foam surface. Thus, the finished composite component can also be cleaned on the metal foam side in a simple way or equipped with other components.
For avkjøling av metallskummet er det f.eks. mulig å anordne, etter reguleringsinnretningen, en avkjølingsanordning med luftutløpsåpninger vendende mot metallskummet. For cooling the metal foam, there is e.g. possible to arrange, after the regulation device, a cooling device with air outlet openings facing the metal foam.
Utførelsen i henhold til krav 7 er særlig lønnsom siden komposittkomponentene ikke blir tatt ut av anordningen for preging og ikke må legges inn i en separat pregeanordning. Dessuten kan pregingen av komposittkomponentene skje individuelt ved den riktige temperatur alt etter benyttet material og stilte krav, ved at det mellom regulerings- og pregeinnretningen enten skjer oppvarming eller avkjøling. Ved bruk av et prege-/skjæreverktøy er en kombinert preging og skjæring i ett arbeidstrinn mulig, hvorved fremstillingskostnader og -tid synker og komponenttoleranser kan minimeres. Komposittkomponenten kan såvel på metallplate- som på metallskumsiden preges med den ønskede kontur. The design according to claim 7 is particularly profitable since the composite components are not taken out of the device for embossing and do not have to be inserted into a separate embossing device. Furthermore, the embossing of the composite components can take place individually at the correct temperature depending on the material used and the requirements set, in that either heating or cooling takes place between the regulation and embossing device. By using an embossing/cutting tool, a combined embossing and cutting in one work step is possible, whereby manufacturing costs and time decrease and component tolerances can be minimized. The composite component can be embossed with the desired contour on both the sheet metal and the metal foam side.
Utførelsen i henhold til krav 8 anvender en støpeform som er enkel å håndtere, som arbeider etter kakeformprinsippet. Metallplaten danner selv underdelen i formen og blir til bestanddel i den senere komposittkomponent. Overdelen av formen kan senkes ned i sideinnfatningsdelen av formen. Dette prinsippet gir en stor frihet med hensyn til komposittkomponentens design: Veggtykkelse og konturer kan vidtgående fritt velges. Med den beskrevne fremgangsmåte kan såvel enkle som kompliserte komposittkomponenter fremstilles. Veggtykkelsen til metallskummet kan herved være konstant eller variere over flaten av metallplaten. Metallplaten kan være plan eller tilformet. Overdelen kan være kongruent med metallplaten eller utformet etter ønske. Ved kraftpåvirkning av overdelen i retning mot metallplaten kan metallskummet i det minste i områdene i nærheten av overflaten bli noe komprimert, slik at det dannes en lukket overflate. Også ved oppvarming av de enkelte støpeformdeler kan en lukket overflate på metallskumsjiktet oppnås. Særlig forvarmes metallplaten, i den hensikt å oppnå en sikker forbindelse. The embodiment according to claim 8 uses a mold which is easy to handle, which works according to the cake mold principle. The metal sheet itself forms the lower part of the mold and becomes a component of the later composite component. The upper part of the mold can be lowered into the side frame part of the mold. This principle gives a great deal of freedom with regard to the design of the composite component: Wall thickness and contours can be chosen very freely. With the described method, both simple and complicated composite components can be produced. The wall thickness of the metal foam can thereby be constant or vary over the surface of the metal plate. The metal plate can be flat or shaped. The upper part can be congruent with the sheet metal or designed as desired. When the upper part is subjected to force in the direction of the metal plate, the metal foam can at least in the areas near the surface become somewhat compressed, so that a closed surface is formed. A closed surface on the metal foam layer can also be achieved by heating the individual mold parts. In particular, the metal plate is preheated, with the aim of achieving a secure connection.
Metallskummet som kreves for tilførselen til støpeformen kan f.eks. fremstilles etter den fremgangsmåte som er beskrevet i WO 91/01387 A1. Alternativt kan også metallskummet avskummes fra smeltedigelen beskrevet i US 4.973.358 A og tilføres støpeformen. Foruten dette kommer også andre fremstillingsmåter for dannelse av metallskum på tale. The metal foam required for the supply to the mold can e.g. is produced according to the method described in WO 91/01387 A1. Alternatively, the metal foam can also be skimmed from the crucible described in US 4,973,358 A and added to the mold. In addition to this, other methods of production for the formation of metal foam are also discussed.
Anordningen i henhold til krav 9 muliggjør en kontinuerlig og automatisert framstillingsprosess, hvorved den eksempelvise metallplate fra en rull raskt, kostnadsgunstig og i uforandret kvalitet raskt bli belagt med metallskum. Ved fraværet av innlegningsarbeidet, slik som i tilfellet med enkelte metallplater, er det mulig med en større produksjon. The device according to claim 9 enables a continuous and automated production process, whereby the exemplary metal sheet from a roll can be quickly coated with metal foam quickly, cost-effectively and in unchanged quality. In the absence of embedding work, as in the case of some metal sheets, a larger production is possible.
Avbøynings- og transportinnretningen kan eksempelvis være kombinert og være utformet som en drevet valse anordnet i området til tilførselsinnretningen. Likeså er det tenkelig å anvende en avbøyningsvalse i området til tilførselsinnretningen og også et transportbånd med stor flate for føring av metallplaten. The deflection and transport device can, for example, be combined and be designed as a driven roller arranged in the area of the supply device. Likewise, it is conceivable to use a deflection roller in the area of the supply device and also a conveyor belt with a large surface for guiding the metal sheet.
En anordning som anvender et transportbånd er kjent fra US 4.973.358 A, imidlertid tjener denne anordningen kun til fremstilling av metallskum: Metallskummet som blir anbragt på det varmebestandige transportbånd stivner under dannelse av en uregelmessig overflate med økende avstand fra smeltedigelen og blir fjernet fra transportbåndet i fast tilstand for videre bearbeiding. Her handler det derimot om som oppfinnelsesgjenstand en anordning for fremstilling av en komplett komposittkomponent, hvorved prinsippet for frembringelse av metallskummet i henhold til US-patentet kan anvendes. Generelt er imidlertid også enhver annen fremgangsmåte for metallskumfremstilling mulig. A device using a conveyor belt is known from US 4,973,358 A, however, this device only serves for the production of metal foam: The metal foam that is placed on the heat-resistant conveyor belt solidifies forming an irregular surface with increasing distance from the crucible and is removed from the conveyor belt in a solid state for further processing. Here, on the other hand, the subject matter of the invention is a device for producing a complete composite component, whereby the principle for producing the metal foam according to the US patent can be applied. In general, however, any other method for metal foam production is also possible.
Med utførelsen av anordningen i henhold til krav 10 muliggjøres det ved en tett sammenstilling av de to stasjonene (belegning, preging) en kontinuerlig fremstilling av komposittkomponenter i en uavbrutt produksjonsprosess. Ved bortfall av innleggs- og uttaksarbeidet mellom stasjonene oppnås en kortere fremstillingstid, og også høyere oppnåelige stykktall og lavere produksjonskostnader. Fremstillingen kan i stor grad være automatisert. With the design of the device according to claim 10, a close assembly of the two stations (coating, embossing) enables a continuous production of composite components in an uninterrupted production process. By eliminating the insertion and removal work between the stations, a shorter production time is achieved, and also higher achievable piece numbers and lower production costs. The production can be largely automated.
Prege- og skjæreinnretningen må i sin nedsenkede posisjon beveges med transportinnretningen for komposittkomponenten, f.eks. ved inngrep ved påsetting på sidestyringer på transportinnretningen. In its lowered position, the embossing and cutting device must be moved with the transport device for the composite component, e.g. in the event of intervention when attaching to the side controls of the transport device.
Krav 11 angir en spesielt fordelaktig anvendelse av en komposittkomponent: Ved kombinasjon av begge komponenter er det på den ene side med metallplaten frembrakt en lakkerbar karosseriytterkledning med nesten hvilken som helst design. Metallskummet på innsiden kan på den annen side fylle forskjellige oppgaver, f.eks. økning av stivheten til den ytre kledning eller lyddemping. Ved anvendelse av metallskum kan eksempelvis en avstivende indre karosseriplate, som i flere tilfeller er kostbar i fremstillingen og som utmerker seg ved en relativ høy vekt, utelates. Samtidig kan det avstivende metallskum overta lydbeskyttelsesoppgaver. Mulige anvendelser er f.eks. komposittkomponenter i henhold til oppfinnelsen som front- og baklokk, taklukedeksel, osv. I tilfellet med frontlokket er det dessuten en fordel at metallskummet ikke er brennbart. Claim 11 states a particularly advantageous application of a composite component: By combining both components, a paintable body cladding with almost any design is produced on one side of the metal sheet. The metal foam on the inside, on the other hand, can fulfill different tasks, e.g. increasing the stiffness of the outer cladding or sound dampening. When using metal foam, for example, a stiffening inner body plate, which in several cases is expensive to manufacture and which is characterized by a relatively high weight, can be omitted. At the same time, the stiffening metal foam can take over sound protection duties. Possible applications are e.g. composite components according to the invention such as front and rear lids, sunroof cover, etc. In the case of the front lid, it is also an advantage that the metal foam is not flammable.
Foruten ytre kledningsdeler kan komposittkomponentene i henhold til oppfinnelsen likeledes også anvendes inne i kjøretøyet, f.eks. som skillevegg mellom motor- og innerrom. Her har i første rekke metallskummet lydabsorpsjonsoppgaver. In addition to external cladding parts, the composite components according to the invention can likewise also be used inside the vehicle, e.g. as a partition between the engine and interior compartment. Here, the metal foam primarily has sound absorption tasks.
Komposittkomponenter i kjøretøyets front- og hekkområde med tilsvarende tykke metallskumsjikt egner seg spesielt til støtdemping ved plastisk deformasjon av metallskummet. Composite components in the vehicle's front and rear areas with correspondingly thick metal foam layers are particularly suitable for shock absorption due to plastic deformation of the metal foam.
Festingen av kledninger eller komponenter på metallskumsjiktet er på en spesielt enkel måte mulig, f.eks. ved bruk av plateskruer. Også plugglignende festeelementer, som med sine mothaker samvirker med de tallrike, tynne skillevegger med skarpe kanter til de blærelignende hulrom til metallskummet, egner seg spesielt godt. The attachment of cladding or components to the metal foam layer is possible in a particularly simple way, e.g. using plate screws. Plug-like fastening elements, which with their barbs cooperate with the numerous, thin dividing walls with sharp edges to the bladder-like cavities of the metal foam, are also particularly suitable.
Et utførelseseksempel av anordningen i henhold til oppfinnelsen skal forklares nærmere ved hjelp av tegningen. Den eneste figuren viser en anordning for fremstilling av en komposittkomponent, sett fra siden i en sterkt skjematisert fremstilling. An embodiment of the device according to the invention will be explained in more detail with the help of the drawing. The single figure shows a device for manufacturing a composite component, seen from the side in a highly schematic representation.
I en smeltedigel 1 befinner det seg en aluminiumlegering 2 i smeltet tilstand. Ved tilførsel av en gass avsetter det seg et gassboblefylt overflatesjikt 3 av aluminiumskum 4 på overflaten av aluminiumsmelten 2. Via en transportinnretning 5 blir aluminiumskummet 4 bragt til en transportvalse 6 som fungerer som en avbøynings- og transportinnretning. Transportvalsen 6 avbøyer en aluminiumplate 7 og fører den til en horisontal platestyring 8. Aluminiumskummet 4 blir anbragt på overflaten 9 av aluminiumplaten 7 av transportinnretningen 5. En reguleringsinnretning 10 som er anordnet over transportvalsen 6 med avstrykningskanter 11 vendende mot transportinnretningen 5 bestemmer tykkelsen av aluminiumskumsjiktet 12. Reguleringsinnretningen 10 har åpninger 13a og 13b for tilførsel av kald eller varm luft. Etter reguleringsinnretningen 10 følger en prege- og skjæreinnretning 14. Den består av en pregeform 15 anordnet på undersiden av aluminiumplaten 7, og et pregestempel 16 og et In a crucible 1 there is an aluminum alloy 2 in a molten state. When a gas is supplied, a gas bubble-filled surface layer 3 of aluminum foam 4 is deposited on the surface of the aluminum melt 2. Via a transport device 5, the aluminum foam 4 is brought to a transport roller 6 which functions as a deflection and transport device. The transport roller 6 deflects an aluminum plate 7 and leads it to a horizontal plate guide 8. The aluminum foam 4 is placed on the surface 9 of the aluminum plate 7 by the transport device 5. A regulation device 10 which is arranged above the transport roller 6 with wiping edges 11 facing the transport device 5 determines the thickness of the aluminum foam layer 12 The regulating device 10 has openings 13a and 13b for supplying cold or warm air. After the regulation device 10 follows an embossing and cutting device 14. It consists of an embossing mold 15 arranged on the underside of the aluminum plate 7, and an embossing stamp 16 and a
skjæreverktøy 17 anordnet på oversiden av aluminiumsjiktet 12. cutting tool 17 arranged on the upper side of the aluminum layer 12.
Såvel transport av aluminiumplaten 7 som transport av aluminiumskummet 4 skjer kontinuerlig. Herved blir aluminiumplaten 7 oppvarmet med ikke viste innretninger såvel foran transportvalsen 6 som på transportvalsen 6 og i platestyringen 8. Ved enden av transportinnretningen 5 blir aluminiumskummet 4 påført aluminiumplaten 7 som beveger seg under transportinnretningen 5. Reguleringsinnretningen 10 begrenser høyden til aluminiumskumsjiktet 12. Den kan også varmes opp, slik at oversiden 18 av aluminiumskumsjiktet 12 blir så glatt som mulig. Gjennom åpninger 13a i reguleringsinnretningen 10 kan det innføres enten varm luft for videre fremme av overflateglatthet eller kald luft for fremskyndelse av stivning av aluminiumskumsjiktet 12. Tilførsel av geleringmiddel gjennom åpningene 13b letter dannelsen av en glatt overflate 18. Both the transport of the aluminum plate 7 and the transport of the aluminum foam 4 take place continuously. Hereby, the aluminum plate 7 is heated with devices not shown both in front of the transport roller 6 and on the transport roller 6 and in the plate guide 8. At the end of the transport device 5, the aluminum foam 4 is applied to the aluminum plate 7 which moves under the transport device 5. The regulation device 10 limits the height of the aluminum foam layer 12. It can is also heated, so that the upper side 18 of the aluminum foam layer 12 becomes as smooth as possible. Through openings 13a in the regulating device 10, either hot air can be introduced to further promote surface smoothness or cold air to accelerate hardening of the aluminum foam layer 12. Supply of gelling agent through the openings 13b facilitates the formation of a smooth surface 18.
Konturen til komposittkomponenten 19 kan bestemmes ved designet til pregeformen 15 og pregestempelet 16. Skjæreverktøyet 17 fraskiller de ferdige komposittkomponenter 19 fra den gjennomløpende aluminiumplaten 7. The contour of the composite component 19 can be determined by the design of the embossing die 15 and the embossing stamp 16. The cutting tool 17 separates the finished composite components 19 from the continuous aluminum plate 7.
