"Fremgangsmåte og innretning ti± profilering av et bånd av elastoplastisk eller plastisk materiale, fortrinnsvis tynnplate" "Procedure and device for profiling a strip of elastoplastic or plastic material, preferably thin sheet"
Den foreliggende oppfinnelse angår en fremgangsmåte og en innretning til å profilere et bånd av elastoplastisk eller plastisk materiale, fortrinnsvis tynnplate. The present invention relates to a method and a device for profiling a strip of elastoplastic or plastic material, preferably thin plate.
Bærende tynnplateprodukter har hittil hovedsakelig vært frem-stilt som lineære bæreelementer, dvs. med en eneste bærende pro-fileringsretning. Grunnen er at der ikke hittil har vært funnet noen metode som i en kontinuerlig linje kan gi bærende profilering i mer enn en retning. Produkter med mer enn en bærende profiler-ingsretning har egenskaper som betydelig utvider anvendelsesområ-dene for tynnplateprodukter og også medfører store fordeler ved nå-værende anvendelsesområder. Load-bearing thin sheet products have so far mainly been produced as linear load-bearing elements, i.e. with a single load-bearing profiling direction. The reason is that so far no method has been found which can provide load-bearing profiling in more than one direction in a continuous line. Products with more than one supporting profiling direction have properties that significantly expand the areas of application for thin sheet products and also entail major advantages in current areas of application.
Med tidligere teknikk har der vært foretatt dyptrekning, dvs. annen enn lineær profilering, mellom to dyner, idet kantpartiene rundt den del som ble dyptrukket, ble låst mot sideforkyvning og dyptrekningsmønsteret således ble dannet ved strekkspenninger i båndet med derav følgende plastisk deformasjon. For at dynene skal kunne føres vinkelrett mot båndet ved dyptrekningen, må dette være låst mot sidebevegelse, noe som medfører at båndet må holdes stille under trekningsoperasjonen. Hvis båndet som skal dyptrekkes, dess-uten er lenger enn dynen, må dyptrekningen utføres i et antall sær-skilte skritt, noe som sinker matrialgjennomgangen. With previous techniques, deep drawing, i.e. other than linear profiling, has been carried out between two quilts, as the edge parts around the part that was deep drawn were locked against lateral folding and the deep drawing pattern was thus formed by tensile stresses in the strip with consequent plastic deformation. In order for the quilts to be guided perpendicularly to the belt during deep drawing, this must be locked against lateral movement, which means that the belt must be held still during the drawing operation. If the strip to be deep-drawn is, moreover, longer than the quilt, the deep-drawing must be carried out in a number of separate steps, which slows down the material throughput.
Hensikten med den foreliggende oppfinnelse er å skaffe en fremgangsmåte og en innretning til å profilere fortrinnsvis tynnplateprodukter i flere retninger. Samtidig tilstrebes det at hele frem-stillingsprosessen skal skje i en eneste linje uten materialstans, og at der ikke i det ferdige produkt skal forekomme indre spenninger som gir tendens til krumning eller skjevhet. The purpose of the present invention is to provide a method and a device for profiling preferably thin sheet products in several directions. At the same time, the aim is that the entire manufacturing process should take place in a single line without material stoppages, and that there should not be internal stresses in the finished product that tend to cause curvature or distortion.
Dette oppnås ved hjelp av en fremgangsmåte.og en innretningThis is achieved by means of a method and a device
med kjennetegn som angitt i patentkravene.with characteristics as stated in the patent claims.
I det følgende vil et utførelseseksempel på oppfinnelsen bli beskrevet under henvisning til tegningen. In the following, an embodiment of the invention will be described with reference to the drawing.
Fig. 1 viser skjematisk et valsepar til å bevirke forlengelseFig. 1 schematically shows a pair of rollers to effect extension
i det minste i et parti av det bånd som skal profileres.at least in part of the band to be profiled.
Fig. 2 viser båndet etter gjennomløp av valseparet på fig. 1. Fig. 2 shows the belt after passing through the pair of rollers in fig. 1.

Fig. 4 viser båndet etter passering av pregningsvalsene på fig. 3. Fig. 4 shows the belt after passing the embossing rollers in fig. 3.
Fig. 5 viser båndet etter lineær valseformning.Fig. 5 shows the strip after linear roll forming.
Fig. 6 viser skjematisk en profileringslinje for fremstillingFig. 6 schematically shows a profiling line for production
av blikkprofilet på. fig. 5.of the tin profile on. fig. 5.
På fig. 1 sees det første skritt av bearbeidelsen av et emne i form av et avlangt bånd 1 som passerer mellom to valser 2. Som det fremgår av figurene, har valsene 2 mindre bredde enn båndet 1. Har valsene 2 et tilstrekkelig høyt gjensidig kontakttrykk, vil det parti 3 av båndet som bearbeides av valsene 2, bli tynnere. Siden ikke noe materiale kan forsvinne fra båndet 1, medfører det at det fortynnede parti 3 vil bli tøyet hovedsakelig i lengderetningen for båndet 1. Ytterpartiene 4 av båndet 1 på begge sider blir ikke bearbeidet av valsene 2 og undergårderfor heller ikke noen lengde-forandring. In fig. 1 shows the first step in the processing of a blank in the form of an elongated belt 1 that passes between two rollers 2. As can be seen from the figures, the rollers 2 have a smaller width than the belt 1. If the rollers 2 have a sufficiently high mutual contact pressure, it will part 3 of the tape processed by the rollers 2 become thinner. Since no material can disappear from the belt 1, it means that the diluted part 3 will be stretched mainly in the longitudinal direction of the belt 1. The outer parts 4 of the belt 1 on both sides are not processed by the rollers 2 and there is no change in length either.
På fig. 2 sees et avsnitt av et bånd .1 som har vært bearbeidet av valsene 2. Fortynningen og forlengelsen av det bearbeidede, altså sentrale parti 3, medfører at dette parti danner et uregelmessig bølgemønster som antydet på figuren. In fig. 2 shows a section of a strip .1 which has been processed by the rollers 2. The thinning and lengthening of the processed, i.e. central part 3, means that this part forms an irregular wave pattern as indicated in the figure.
Istedenfor bare å forlenge båndet i ett parti som beskrevet under henvisningen til fig. 1 og 2, kan det selvsagt tenkes.å forlenge båndet i to eller flere parallelle partier under lévning av mellomlig-gende partier som ikke forlenges. Dette kan man oppnå ved å utforme valsene slik at et sentralt parti av det fremmatede bånd ikke blir utsatt for trykk. Instead of simply extending the band in one section as described with reference to fig. 1 and 2, it is of course conceivable to extend the tape in two or more parallel sections, leaving intermediate sections which are not extended. This can be achieved by designing the rollers so that a central part of the fed belt is not exposed to pressure.
Etter at båndet 1 er forlenget i sitt sentrale parti 3, lar man det passere mellom to pregevalser 5, f.eks. som vist på fig. 3. Pregevalsene 5 har slik avpasset mønstergeometri at forlengelsen i det sentrale bølgede parti av båndet 1 i forhold til dettes plane ytter-parti.er 4 blir opptatt. Resultatet av denne mønstervalsning blir et dypmønstret bånd 1' f.eks. som vist på fig. 4, med innpregninger 6 som forløper på tvers av lengderetningen av båndet 1' og i innbyrdes avstand. Det skal i den forbindelse påpekes at der ved mønster-valsningen fås. et bånd 1 uten generende egenspenninger. En annen After the strip 1 has been extended in its central part 3, it is allowed to pass between two embossing rollers 5, e.g. as shown in fig. 3. The embossing rollers 5 have such an adapted pattern geometry that the extension in the central wavy part of the band 1 in relation to its flat outer part 4 is taken up. The result of this pattern rolling is a deeply patterned band 1', e.g. as shown in fig. 4, with indentations 6 extending across the longitudinal direction of the band 1' and at a distance from each other. In this connection, it should be pointed out that the pattern rolling results in a band 1 without disturbing inherent stresses. Another
stor fordel ved fremgangsmåten ifølge oppfinnelsen er at båndet 1'major advantage of the method according to the invention is that the band 1'
på fig. 4 kan fås i en kontinuerlig prosess uten at det på noe tids-punkt stoppes. on fig. 4 can be obtained in a continuous process without stopping at any point.
Hvis det ønskes, kan båndet 1' direkte, altså uten stans, føres videre gjennom et konvensjonelt rulleformningsverk som linjeprofile-rer de inntil da ubearbeidede ytterpartier 4 av båndet 1'. Der kan dermed f.eks. fås et blikkprofil 1'' som vist på fig. 5. If desired, the strip 1' can be directly, i.e. non-stop, passed on through a conventional roll forming plant which line-profiles the hitherto unworked outer parts 4 of the strip 1'. There can, for example, a tin profile 1'' is obtained as shown in fig. 5.
Fig. 6 er et skjema for et utførelseseksempel på en profileringslinje hvor innretningen ifølge oppfinnelsen inngår. Stasjon A har et eller flere valsepar 2 i henhold til fig. 1 til å bevirke forlengelse i visse partier av båndet 1. Stasjonen B har et eller flere par pregevalser, f.eks. som vist ved 5 på fig. 3, til å bevirke dypmønstring av det eller de forlengede partier C. Stasjon C utgjøres av en rulleformningslinje av konvensjonell type til å linje-profilere ytterpartiene 4 av båndet l<1>slik at der fås et blikkprofil 1' som vist på fig. 5. Fig. 6 is a diagram for an embodiment of a profiling line in which the device according to the invention is included. Station A has one or more roller pairs 2 according to fig. 1 to cause elongation in certain parts of the belt 1. The station B has one or more pairs of embossing rollers, e.g. as shown at 5 in fig. 3, to cause deep patterning of the extended part(s) C. Station C consists of a roll forming line of a conventional type to line-profile the outer parts 4 of the band 1<1> so that a tin profile 1' is obtained as shown in fig. 5.
Den gjensidige plassering av de forskjellige stasjoner som er vist på fig. 6 utgjør bare et eksempel. Således er det også mulig å plassere stasjonene A og B i stasjon C eller etter stasjon C i båndets matningsretning. The mutual location of the various stations shown in fig. 6 is only an example. Thus, it is also possible to place stations A and B in station C or after station C in the belt's feeding direction.
Det skal videre påpekes at fremgangsmåten og innretningen ifølge oppfinnelsen ikke behøver å omfatte rulleformningsskrittet, resp. rulleformningslinjen, men det er også mulig å anvende bånd av en form som vist ved 1' på fig. 4 uten ytterligere formning, f.eks. som radiatorplate. Enn videre kan man også tenke seg en annen etterbe-handling av båndet enn rulleformning. It should further be pointed out that the method and the device according to the invention do not need to include the roll forming step, resp. the roll forming line, but it is also possible to use bands of a shape as shown at 1' in fig. 4 without further shaping, e.g. as a radiator plate. Furthermore, one can also think of a different post-treatment of the strip than roll forming.
Heller ikke forøvrig er oppfinnelsen begrenset til det beskre-vede utførelseseksempel, idet utførelsen fritt kan varieres innen patentkravenes ramme. Furthermore, the invention is not limited to the described embodiment, as the embodiment can be freely varied within the framework of the patent claims.
