Description

Opfindelsen vedrører et apparat til fremstilling af profilerede, pladeformede emner, fortrinsvis tagsten af beton eller et lignende abrasivt materiale, ved hjælp af en drejeligt lejret komprimeringsvalse, og en i produktionsretningen umiddelbart bagvedliggende, formgivende, fast anbragt glitningsindretning, nedenunder hvilken de med beton fyldte forskallings-forme føres igennem i produktionsretningen, og hvorved emnerne, der befinder sig deri, bliver komprimeret og profileret, og hvorved komprimeringsvalsen og/eller glitningsindretningen på de overfladeområder, der er udsat for slid, haren af hårdmetal bestående belægning.BACKGROUND OF THE INVENTION 1. Field of the Invention This invention relates to an apparatus for the production of profiled slab, preferably concrete tile or similar abrasive material, by means of a pivotally mounted compression roller, and a sliding device located immediately behind the molding, under which the concrete-filled formwork molds are passed through in the production direction, whereby the articles contained therein are compressed and profiled, whereby the compression roller and / or the gliding device on the surface areas exposed to abrasion have the hard metal coating.

Et sådant apparat, ved hvilket den af værktøjsstål bestående basis bærer en af et hårdere materiale f.eks. wolframkarbid bestående belægning, som er forbundet med sin basis ved svejsning, lodning eller hårdlodning, kendes allerede fra det britiske patentskrift nr. 739.860.Such an apparatus in which the tool steel base carries one of a harder material e.g. tungsten carbide coating which is associated with its base by welding, brazing or brazing is already known from British Patent Specification No. 739,860.

Ved fremstilling af et sådant apparat og især ved fremstilling af den profilerede glitteindretning består et problem deri at bringe det hårde belægnings-materiale i absolut formnøjagtig overensstemmelse med basis, for derved at sikre den af hensyn til en pålidelig forbindelse mellem delene nødvendige fladekontakt mellem forbindelsesfladerne.In the manufacture of such an apparatus, and in particular in the manufacture of the profiled gliding device, a problem therein is to bring the hard coating material into absolute form-conformity with the base, thereby ensuring the necessary contact between the portions for a reliable connection between the parts.

Ved glitningsindretningen i det ovennævnte allerede kendte apparat fandt man til løsning af dette problem på at opdele såvel dettes basis som dets belægning i enkelte strimler, hvorved hver basisstrimmel var forbundet med en tilsvarende bred strimmel af det materiale, der dannede belægningen. Disse af forskellige materialer bestående strimler blev så føjet sammen til glitnings indretningens fulde bredde og f.eks. spændt sammen med skruebolte.In the glittering device of the above-known apparatus, for solving this problem, it was found to divide both its base and its coating into single strips, each base strip being connected to a correspondingly wide strip of the material forming the coating. These strips of various materials were then joined together to the full width of the glitter device and e.g. tightened together with screw bolts.

Denne byggemåde for glitningsindretningen viser sig dog at være ikke blot dyr og kompliceret, men har også ulemper med hensyn til opdelingen af basen. Det viser sig ønskværdigt at fremstille denne basis kompakt i eet stykke for at sikre dens styrke og sammenhængning og forenkle dens fremstilling.However, this construction method of the glitter device turns out to be not only expensive and complicated, but also has disadvantages with regard to the division of the base. It seems desirable to make this base compact in one piece to ensure its strength and coherence and simplify its manufacture.

Dertil kommer, at de på den ene side til basis og på den anden side til belægningen anvendte materialer udviser forskellige fysiske egenskaber, og at belægningsmaterialet udviser en betragtelig sprødhed. Deraf resulterer f.eks. som følge af temperaturforskelle optrædende formændringer, som medfører beskadigelser, og som har ugunstig indvirkning på styrken af forbindelsen mellem basis og belægningen.In addition, the materials used on the one hand for the base and on the other hand for the coating exhibit different physical properties and that the coating material exhibits considerable brittleness. Hence, e.g. as a result of temperature differences, shape changes that cause damage and which adversely affect the strength of the bond between the base and the coating.

Opgaven for den foreliggende opfindelse er at afhjælpe disse mangler og at udforme et apparat af den i indledningen nævnte art på en sådan måde, at de ovennævnte vanskeligheder undgås.The object of the present invention is to remedy these deficiencies and to design an apparatus of the kind mentioned in the introduction in such a way as to avoid the aforementioned difficulties.

Ifølge opfindelsen er det ved et apparat af denne art indrettet således, at hårdmetalbelægningerne via et af en metal-formstof-blanding fortrinsvis en stål- formstof-blanding bestående mellemlag er forbundet med en fortrinvis af stål bestående basis, i givet fald formomsluttende, f.eks., som allerede kendt, ved hjælp af ind i hinanden gribende, underskåret profilerede federe og noter.According to the invention, in an apparatus of this kind, it is arranged that the cemented carbide coatings are connected, via a metal-plastic mixture preferably a steel-plastic mixture, to a preferably steel-based base, if necessary molded, f. eg, as already known, by means of interlocking, cut profiled fats and notes.

Det er nemlig erkendt, at et sådant mellemlag ved høj klæbestyrke og gode elastiske egenskaber fejlfrit kan udligne belægningens og basens forskellige fysiske egenskaber, og alligevel medføre en overordentlig pålidelig, sejg forbindelse mellem disse, forskellige materialer.It is recognized that such an intermediate layer at high adhesive strength and good elastic properties can flawlessly equalize the different physical properties of the coating and the base, and yet result in an extremely reliable, tough connection between these different materials.

Fordi hårdmetal kun forholdsvis svært lader sig forarbejde til kompliceret profilerede former, kan hård-metalbelægningen på komprimeringsvalsen henholdsvis glitteindretningen være opdelt over disses tilsvarende samlede bredde og sættes sammen af delstykker.Because cemented carbide is only relatively difficult to process into complicated profiled shapes, the hard metal coating on the compression roller or the glitter device can be divided over their corresponding total width and assembled into sections.

Dette lader sig på fordelagtig måde anvende ved fremstilling af tagsten med flere områder dels hvælvede dels plane områder, der strækker sig over den fulde bredde, især til fremstilling af såkaldte romerprofiler. Med henblik herpå skal der udvikles en form på apparatets bestanddele, ved hvilken der kan anvendes en ønskelig enkel, robust og mod brudrisiko ufølsom form på hårdmetalbelægningerne.This is advantageously used in the manufacture of multi-area roof tiles partly vaulted and flat areas extending over the full width, especially for the preparation of so-called Roman profiles. To this end, a mold must be developed on the constituents of the apparatus, using a desirable simple, robust and insensitive shape on the cemented carbide coating.

På fordelagtig måde kan glitningsindretningens hård-metalbelægning - svarende til profilet af tagstenene, der skal fremstilles, og som over deres bredde udviser dels plane dels hvælvede områder - være opdelt i lige så mange flade og hvælvede delstykker, som er forbundet med basis med deres længdekanter føjet tæt til hinanden.Advantageously, the hard-metal coating of the glitter device - similar to the profile of the tiles to be manufactured and which exhibit over their width partly planar and partly vaulted areas - can be divided into as many flat and vaulted sections as are connected to the base with their longitudinal edges. added close to each other.

På samme måde kan imidlertid med fordel også komprimeringsvalsens basis svarende til tagstenenes profil være inddelt i sådanne delstykker, som så er lejret på en fælles drivaksel. Derved fremkommer som yderligere fordel, at sådanne delstykker i tilfælde af et brud kan udskiftes henholdsvis fornys enkeltvis, uden at en udskiftning af hele bestanddelen er nødvendig. Fordelagtigvis hører der for de hvælvede områder, de plane områder og det med falser forsynede område af tagstenenes profilering særskilte delstykker til komprimeringsvalsens basis.In the same way, however, advantageously the base of the compaction roller corresponding to the profile of the roof tiles may also be divided into such sections which are then mounted on a common drive shaft. Thus, as an additional advantage, in the event of a breakage, such parts can be replaced or renewed individually without the need for a replacement of the entire component. Advantageously, for the vaulted areas, the flat areas and the creased area of the roofing profiles, there are separate parts for the base of the compression roller.

På formålstjenlig måde besidder kun de stærkt belastede, nemlig kun de plane områder og de med falser forsynede randområder af komprimeringsvalsen en af hårdmetal bestående belægning, som er fastgjort til basis ved hjælp af mellemlaget. I de hvælvede områder, som i forvejen påvirkes og slides mindre, behøves en sådan belægning erfaringsmæssigt ikke. Delstykkerne til de hvælvede områder kan derfor bestå helt af et materiale, der er blødere i sammenligning med belægningens hårdmetal, især da det drejer sig om kompakt udformede og forholdsvis små delstykker, som i forvejen ikke er udsat for nogen brudrisiko.Conveniently, only the heavily loaded, namely only the planar regions and the rimed rim regions of the compression roller possess a cemented carbide coating which is fixed to the base by means of the intermediate layer. In the vaulted areas, which are already affected and less abrasive, such an coating is not needed in experience. The sections for the vaulted areas can therefore consist entirely of a material which is softer in comparison with the carbide of the coating, especially since these are compactly designed and relatively small sections which are not already exposed to fracture risk.

I det følgende forklares opfindelsen nærmere ved hjælp af de på tegningen som eksempler viste udførelsesformer af apparatets bestanddele. På disse tegninger viser fig. 1 skematisk set fra siden den kendte grund- læggende opbygning af et apparat ifølge opfindelsen fig. 2 det tilhørende billede set fra oven ifølge pilen II på fig. 1, og fig. 3 et billede set forfra i retning af pilen III på fig. 1, hvorved emnet for tydeligheds skyld kun er vist i snit, fig. 4 og 5 viser et tværsnit henholdsvis et længdesnit i glitningsindretningen, og fig. 6 er et længdesnit gennem en komprimerings-valse, fig. 7 viser et tværsnit gennem en anden udførelsesform af en glitningsindretning, og fig. 8 er et snit i planet VIII i fig. 7.In the following, the invention is explained in more detail by means of the exemplary embodiments of the components of the apparatus. In these drawings, FIG. 1 is a schematic side view of the known basic structure of an apparatus according to the invention; 2 is a top plan view according to arrow II of FIG. 1, and FIG. 3 is a front view of the arrow III in FIG. 1, wherein the blank is shown in section only for the sake of clarity; FIG. 4 and 5 show a cross section and a longitudinal section, respectively, of the glitter device; 6 is a longitudinal section through a compression roller; FIG. 7 shows a cross section through another embodiment of a glitter device; and FIG. 8 is a sectional view of plane VIII of FIG. 7th

Fig. 1 til 3 viser først forrådsbeholderen 1, i hvilken den beton, der skal forarbejdes med en kornstørrelse på tilblandingsstoffet på ca. 0 til 3 mm, bliver tilført fra en blander, og i hvilken den af den roterende fordeler, f.eks. en takvalse 2, der har til opgave af fordele materialet regelmæssigt, bliver transporteret ind under komprimeringsvalsen 3, den såkaldte "roller". Til undersiden af denne komprimeringsvalse 3 tilføres yderligere på et formbrædt 4 (fig. 3) forskallingsformer 5 til de emner, der skal formes.FIG. 1 to 3 first show the storage container 1, in which the concrete to be processed with a grain size of the admixture of approx. 0 to 3 mm is supplied from a mixer and in which the rotary distributor, e.g. a roof roller 2, which has the task of distributing the material regularly, is transported under the compression roller 3, the so-called "roller". To the underside of this compression roller 3, further formwork 5 (form 3) forms formwork 5 for the workpieces to be formed.

Fra komprimeringsvalsen 3, der ligesom takvalsen 2 roterer med et bestemt omdrejningstal, bliver betonen, der forlader forrådsbeholderen 1 og trænger ind i forskallingsformene 5, komprimeret og derved samtidig rigtigt doseret.From the compression roll 3, which, like the roof roll 2, rotates at a certain speed, the concrete leaving the storage container 1 and penetrating into the formwork 5 is compressed and thereby properly dosed.

Nu kommer de med den komprimerede beton fyldte forskallingsforme 5 ind under glitningsanordningen 7, der er skråstillet i en bestemt indfaldsvinkel i forhold til formbrædtet 4 og med sin forside, der er formet til en spids kant og vender ind mod komprimeringsvalsen 3, umiddelbart slutter tangentielt op til dennes underside. Denne glitningsanordning 7, den såkaldte "slipper", presser, glitter og profilerer endeligt den beton, der befinder sig i de forbivandren-de forskallingsforme 5 og kan indstilles ved hjælp af en trykplade 8 i forhold til komprimeringsvalsen 3 for at kunne regulere størrelsen på den mellem disse bestanddele bestående spalte. Denne størrelse måtte ved de hidtil kendte apparater af denne art ved stadig slitage på bestanddelene til stadighed med relativt korte tidsintervaller reguleres. Glitningsanordningen 7 holdes af en bro, der spænder over formbrædtet 4 og forskallingsformene 5' s transportvej . Forskallingsformenes 5 fremstillings- og transportretning er angivet med pilen 10.Now, the formwork-filled formwork 5 filled with the compressed concrete comes under the gliding device 7, which is inclined at a certain angle of incidence with respect to the moldboard 4 and with its front shaped to a pointed edge and faces the compression roller 3, immediately tangentially ends up to its underside. This glitter device 7, the so-called "release", finally compresses, glitter and profiles the concrete contained in the transient formwork 5 and can be adjusted by means of a pressure plate 8 relative to the compression roll 3 to be able to control the size of the gap between these components. This size had to be adjusted for the known apparatus of this kind by constant wear on the components at relatively short intervals of time. The gliding device 7 is held by a bridge spanning the molding board 4 and the formwork transport path of the formwork 5. The direction of manufacture and transport of the formwork 5 is indicated by arrow 10.

For så vidt tilhører apparatets principielle opbygning den allerede bekendte teknik.To this extent, the principle construction of the apparatus belongs to the technique already known.

Ifølge opfindelsen fremviser nu den på figurerne 4 og 5 i større målestok i længde- og tværsnit fremstillede glitningsanordning 7 en af støbe- eller smedestål bestående basis 11, der via et mellemlag 12, beståen de af en til at begynde med støbedygtig, hærdningsbar blanding af ca. 80% stål og 20% epoxyharz, er forbundet med en af det såkaldte hårde metal bestående belægning 13.In accordance with the invention, the longitudinal and cross-sectional glittering device 7, made in FIGS. 4 and 5, now shows a casting or forging steel 11 base which, via an intermediate layer 12, consists of a initially durable, curable mixture of ca. 80% steel and 20% epoxy resin are connected to one of the so-called hard metal coating 13.

Betegnelsen hårdt metal benyttes som bekendt ved en sintret metal-hårdlegering, der består af et eller flere hårdstoffer, f.eks. wolfram, titan, tantalkar-bid osv. med et bindemetal fra jerngruppen, for det meste kobolt, men også nikkel eller jern, og fremviser en særlig høj hårdhed og slidbestandighed.The term hard metal is used as is known in the case of a sintered metal hard alloy consisting of one or more hardeners, e.g. tungsten, titanium, tantalum carbide, etc., with a binder metal from the iron group, mostly cobalt, but also nickel or iron, and exhibits a particularly high hardness and abrasion resistance.

Forbindelsen mellem basen 11 og belægningen 13 fremkommer i det væsentligste allerede ved sammenkitningen ved hjælp af mellemlaget 12, dog kan - ifølge udførelseseksemplet på figurerne 4 og 5 - yderligere også underskårne, profilerede federe 14 og noter 15 anbringes til formsluttende sikring af denne forbindelse, således som de er fremstillet på figur 5.The connection between the base 11 and the coating 13 is substantially already established by the interconnection by means of the intermediate layer 12, however - according to the exemplary embodiment of Figures 4 and 5 - further cut, profiled greases 14 and grooves 15 can also be applied to formally secure this connection, thus as shown in Figure 5.

Som det yderligere fremgår af fig. 4, består belægningen af delstykker, der svarer til de lige, henholdsvis de hvælvede flader på glitningsanordningen 7 og med deres længderande tæt sammenføjet er forbundet med basen 11. Belægningen 13 kunne dog - inden for opfindelsens rammer - også bestå af eet stykke. En randdel 27 på glitningsanordningen 7 er profileret med falser 26; den kan i sin helhed bestå af hårdt metal.As further shown in FIG. 4, the coating consists of parts corresponding to the straight and the vaulted surfaces of the glitter device 7 and with their longitudinal edges closely joined to the base 11. However, the coating 13 could - within the scope of the invention - also consist of one piece. An edge portion 27 of the glider 7 is profiled with seams 26; it may consist entirely of hard metal.

Komprimeringsvalen 3 viser den på fig. 6 synlige opbygning ifølge opfindelsen, og her består dens basis 16 af delstykkerne 17, 17', 18 og 19, der er sat i række på drivakslen og ved hjælp af en kile 21 og en møtrik 22 holdes vridningsfaste.The compression roller 3 shows that of FIG. 6 is visible structure according to the invention, and here its base 16 consists of the parts 17, 17 ', 18 and 19, which are arranged in a row on the drive shaft and by means of a wedge 21 and a nut 22 are held torsionally fixed.

Også denne komprimeringsvalse 3 omfatter - svarende til profileringen på de emner 6, der skal fremstilles - dels lige dels hvælvede profilerede områder, og her er delstykkerne 17 og 17' anbragt på komprimeringsvalsen 3's mindre belastede hvælvede områder, hvorimod begge delstykkerne 18 er anbragt på de stærkere belastede lige områder og delstykket 19 på det randområde, som tagstensemnets 6 sideflade danner.Also, this compression roller 3 comprises - similar to the profiling of the workpieces 6 to be manufactured - partly equally vaulted profiled areas, and here the subpieces 17 and 17 'are placed on the less stressed vaulted regions of the compression roll 3, whereas both subpieces 18 are placed on the stronger loaded straight areas and the sub-piece 19 on the edge area formed by the lateral surface of the tile blank 6.

De små delstykker 17 og 17' kan, fordi de belastes mindre, fremstilles af et forholdsmæssigt blødere og lettere bearbejdbart hårdt metal i eet stykke.The small parts 17 and 17 ', because they are less loaded, can be made of a relatively softer and more easily workable hard metal in one piece.

Derimod må de indbyrdes ens delstykker 18 og delstykket 19 hver for sig bære en af hårdt metal bestående belægning 23 for at være tilstrækkeligt slidstærke. Delstykkernes 18 belægninger 23 og delstykkets 19 belægning 24 er igen via et mellemlag 25 af den ovenfor allerede nævnte hertil egnede metal-kunstof^-blanding forbundet med basen 16, henholdsvis dennes delstykker.On the other hand, the mutually identical parts 18 and the part 19 must individually wear a hard metal coating 23 to be sufficiently durable. The coatings 23 of the parts 18 and the coating 24 of the parts 19 are again connected to the base 16 or their parts by means of an intermediate layer 25 of the above-mentioned suitable metal-plastic material mixture.

Ved den varierede udførelsesform af en glitnings-anordning 7 ifølge figurerne 7 og 8 fremviser den af et stykke formede hårdmetalbelægning 13 på den side, der vender mod basen, fordybninger, i hvilke der er loddet skruebøsninger 19. Også den med falser 26 profilerede randdel 27 af glitningsanordningen bærer sådanne skruebøsninger 29. Hårdmetalbelægningen 13 er forbundet med basen 11 ved hjælp af skruer 30 - fortrinsvis de såkaldte imbusskruer, der for at kunne drejes, har en kantet fordybning i toppen - der er skruet til i disse skruebøsninger 29 og går igennem basen 11.In the varied embodiment of a glitter device 7 according to Figures 7 and 8, the piece of carbide-shaped coating 13 on the side facing the base shows recesses in which are soldered screw bushings 19. Also the rim portion 27 profiled with seams 26 of the glitter device such screw bushes 29. Carbide coating 13 is connected to the base 11 by means of screws 30 - preferably the so-called hex screws which, to be rotatable, have an angular depression at the top - which are screwed into these screw bushes 29 and pass through the base 11th

På den forside, der vender bort fra komprimeringsval-sen, er glitningsanordningen forbundet med en liste 31, der lapper over kanten af hårdmetalbelægningen 13, ved hjælp af skruer 32.On the front facing away from the compression roller, the gliding device is connected to a strip 31 which overlaps the edge of the cemented carbide 13 by means of screws 32.

Denne liste 31, der består af stål, overtager en del af de på hårdmetalbelægningen 13 virkende stærke trykkræfter og sikrer derved dennes forbindelse med giitningsanordningens 7 basis 11.This list 31, which consists of steel, takes over some of the strong compressive forces acting on the cemented carbide 13 and thereby ensures its connection with the base 11 of the casting device 7.

Ifølge en meget fordelagtig for opfindelsens kendetegnende del består glitningsanordningens 7 hårdme-talbelægning 13 på den umiddelbart til komprimerings-valsen 3 tilsluttende randområde 13' (fig. 8) af et blødere materiale end på det øvrige med slitage stærkere belastede område, hvorved begge disse områder af forskellig hårdhed i grænsezonen 33 kontinuerligt går over og ind i hinanden.According to a very advantageous part of the invention, the hard metal coating 13 of the glitter device 7 consists of a softer material 13 adjacent to the compression roller 3 (Fig. 8) than the other with a more heavily loaded area, whereby both these areas of different hardness in the boundary zone 33 continuously goes over and into each other.

Bestanddelenes mellemlag 12 henholdsvis 25 ved appa-ratet ifølge opfindelsen tjener - som allerede tidligere oplyst - til udligningen af de forskellige formændringer af de forskellige materialer, af hvilke disse bestanddele sammensættes, og de forhindrer på den måde forekomsten af truende indre spændinger; de sørger samtidig for en pålidelig binding af belægningerne 13, 23, 24 til disse bestanddeles baser 11 henholdsvis 16. Materialet til disse mellemlag 12 henholdsvis 25 lader sig før hærdningen uden vanskelighed hælde ned mellem baserne og belægningerne og derpå hærde.The intermediate layers 12 and 25, respectively, of the apparatus according to the invention serve - as already stated - to compensate for the various shape changes of the various materials of which these components are composed, thus preventing the occurrence of threatening internal stresses; at the same time, they provide a reliable bonding of the coatings 13, 23, 24 to the bases 11 and 16 of these constituents, respectively. The material for these intermediate layers 12 and 25, respectively, is easily poured before curing between the bases and the coatings and then cured.

Brugstiden for de ifølge opfindelsen formede apparat-bestanddele er, i sammenligning med de hidtil benyttede, af smedet samt støbt stål bestående ensartede bestanddele, betydeligt forhøjet: Mens tidligere kendte bestanddele efter produktionen af ca. 225.000 enheder måtte udskiftes, fordi slitagen lokalt var blevet så stor, at emnernes måltolerancer ikke mere kunne overholdes, viste de ifølge opfindelsen formede bestanddele også efter produktionen på mere end fem millioner enheder endnu ingen nævneværdig slitage.The useful life of the device components according to the invention is considerably increased compared to the previously used, forged and cast steel consisting of uniform components: whereas previously known components after the production of approx. 225,000 units had to be replaced because the wear had become so large locally that the target tolerances of the items could no longer be observed, the components formed according to the invention also showed no significant wear after the production of more than five million units.

Det er en yderligere værdifuld fordel ved sådanne bestanddele, at de justeringer i glitningsanordningen i forhold til komprimeringsvalsen, der var påkrævede ved de tidligere kendte apparater med korte tidsintervaller for at tage hensyn til slitagen, gøres o-verflødige.It is a further valuable advantage of such constituents that the adjustments in the gliding device to the compression roller required by the prior art devices at short intervals of time to take into account the wear are made superfluous.

Gennem styrken i de ifølge opfindelsen formede, formgivende bestanddele af apparatet er en regelmæssig, konstant høj kvalitet og en vidtgående mål- og vægt-nøjagtighed af emnerne optimalt sikret.Through the strength of the inventive molding components of the apparatus, a regular, constant high quality and far-reaching measurement and weight accuracy of the workpieces is optimally ensured.
