Menetelmä ja laitteisto pitkänomaisten teräskappaleiden, varsinkin betoniterästen ja teräsprofiilien, pinnoittamiseksi Tämän keksinnön kohteena on patenttivaatimuksen 1 johdannon mukainen menetelmä pitkänomaisten teräskappaleiden, varsinkin betoniterästen ja teräsprofiilien, pinnoittamiseksi.The present invention relates to a method according to the preamble of claim 1 for coating elongate steel bodies, in particular reinforcing bars and steel profiles.
Keksinnön kohteena on myös menetelmän toteuttamiseen käytettävä laitteisto.The invention also relates to an apparatus for carrying out the method.
On tunnettua, että erilaisia teräspintoja voidaan märkämaa-lata erilaisin sively- ja ruiskutusmenetelmin. On myös tunnettua, että vaikeisiin rasitusolosuhteisiin tarvitaan useita päällekkäisiä maalikerroksia, jotta muodostuu riittävän tiivis ja paksu kerros korroosioneston varmistamiseksi.It is known that different steel surfaces can be wet-loaded by different coating and spraying methods. It is also known that for difficult stress conditions, several overlapping layers of paint are required to form a sufficiently dense and thick layer to ensure corrosion prevention.
On myös tunnettu tosiasia, että jokainen maalikerros tai pinnoitekerros vaatii oman käsittelynsä ja kuivumisensa (useita päiviä), ja mitä pienempidimensioisia kappaleet ovat, sitä vaikeampaa on savuttaa riittävän tasaista kalvoa manuaalisesti. Eikä moninkertaisia maalauskoneita ole olemassakaan, sillä märkää tuotetta ei voi kannattaa siten, ettei se vaurioituisi käsittelyssä.It is also a known fact that each layer of paint or coating requires its own treatment and drying (several days), and the smaller the dimensional pieces, the more difficult it is to smoke a sufficiently even film manually. And there are no multiple painting machines, because a wet product cannot be supported without being damaged during handling.
Niinpä esim. julkaisu GB 2 025 587 koskee yleensä jäähdytys-nesteen käyttöä kuumennetun materiaalin jäähdytyksessä.Thus, for example, GB 2 025 587 generally relates to the use of a coolant in cooling a heated material.
Julkaisu GB 2 082 739 koskee puolestaan posliinin emalointia kuumennusuunissa "pyykkinaru"-tyyppistä ripustusratkaisua käytettäessä. Julkaisu DE 3 248 234 taas koskee kattotiilien kuljetusta tunneliuuniin poikittaisten ripustustankojen varassa. Julkaisu DE 3 207 345 vihdoin koskee metallikappa-leiden kuljetusta uuniin ripustuskoukkujen varassa.GB 2 082 739, on the other hand, relates to the enamelling of porcelain in a heating oven using a hanging solution of the "clothesline" type. DE 3 248 234, on the other hand, relates to the transport of roof tiles to a tunnel kiln on transverse suspension bars. DE 3 207 345 finally relates to the transport of metal pieces to a furnace on hanging hooks.
On siis huomattava, että kolmessa viimeksi mainitussa tapauksessa, jotka koskevat kappaleiden kuljetusta uuniin 2 84030 tai sentapaiseen, nämä kappaleet on ripustettu koukuista tai sentapaisista roikkumaan, jolloin niiden koko pinta ei ole vapaasti pinnoitettavissa ja sintrattavissa.It should therefore be noted that in the latter three cases, which concern the transport of pieces to an oven 2 84030 or the like, these pieces are hung from hooks or the like so that their entire surface cannot be freely coated and sintered.
Tämän keksinnön tarkoituksena on poistaa edellä kuvatussa tunnetussa tekniikassa esiintyvät haitat ja saada aikaan aivan uudentyyppiset menetelmä ja laitteisto pitkänomaisten teräskappaleiden pinnoittamiseksi.The object of the present invention is to obviate the disadvantages of the prior art described above and to provide a completely new type of method and apparatus for coating elongate steel pieces.
Keksintö perustuu mm. seuraaviin ajatuksiin. Kyseessä on automaattinen laitteisto, jolla voidaan esim. rullaratamaista kuljetinta ja erilaisia ohjauskelkkoja sekä erikoiskumitettu-ja, vastakkain puristuvia vetoteloja käyttämällä työstää erittäin ohutdimesioisiakin teräksiä sintraantumisprosessin läpi koskematta pinnoittetuja pintoja ennen niiden valmistumista.The invention is based on e.g. to the following thoughts. This is an automatic machine which, for example, can be used to process even very thin steels through a sintering process without touching the coated surfaces before they are finished, using, for example, a roller conveyor and various guide carriages as well as special rubberized, oppositely compressing traction rollers.
Teräkset jauhepinnoittuvat vapaasti roikkuen esikuumennuksen jälkeen sarjalla automatisoituja, trapetsikiinnityksellä sovitettuja staattisia jauhepistooleita. Pinnoitetut teräkset kulkevat pyörrevirtausuunin läpi, ja sintraantumisreaktio tapahtuu n. 60...120 sekunnissa.The steels are powder coated freely after preheating with a series of automated, trapezoidally fitted static powder guns. The coated steels pass through a vortex flow furnace, and the sintering reaction takes place in about 60 ... 120 seconds.
Käytetään erillistä pneumaattisylintereillä varustettua mär-kärullaa, jäähdytys-suuttimia (valuva vesi) sekä erikoisku-mitettuja, vesijäähdytteisiä vetoteloja. Valmiiksi sintratun tuotteen jatkosiirto tapahtuu elektronisen tarkastuslaitteen läpi.A separate wet roller with pneumatic cylinders, cooling nozzles (running water) and specially measured, water-cooled drive rollers are used. The pre-sintered product is passed on through an electronic inspection device.
Täsmällisemmin sanottuna keksinnön mukaiselle menetelmälle on pääasiallisesti tunnusomaista se, mikä on esitetty patenttivaatimuksen 1 tunnusmerkkiosassa.More specifically, the method according to the invention is mainly characterized by what is set forth in the characterizing part of claim 1.
Keksinnön mukaiselle laitteistolle on puolestaan tunnusomaista se, mikä on esitetty patenttivaatimuksen 3 tunnusmerkkiosassa.The apparatus according to the invention, in turn, is characterized by what is set forth in the characterizing part of claim 3.
Keksinnön avulla saavutetaan huomattavia etuja. Niinpä pääl-lystysajoissa voitetaan aikaisempaan tekniikkaan verrattuna 3 84030 useita päiviä, saadaan tasaista, laadukasta tuotetta edullisemmin kuin aikaisemmin myös raskaissa upotusrasitustapauk-sissa, koristepinnoissa ym. Laskennallisesti keksinnön mukainen laitteisto pystyy suorittamaan esipuhdistuksen ja kolminkertaisen maalauksen n. 10 kertaa manuaalista nopeammin ja samalla laadullisesti paremmin.The invention provides considerable advantages. Thus, 3,84030 several days can be overcome in coating times compared to the prior art, a smooth, high-quality product is obtained more cheaply than before, even in heavy immersion stresses, decorative surfaces, etc. Computationally, the apparatus according to the invention can perform pre-cleaning and triple painting about 10 times faster and manual .
Keksinnön avulla voidaan myös voittaa aikaa, vähentää käsit-telykustannuksia, miehistöä, hallitiloja sekä lämmön ja energian tarvetta.The invention can also save time, reduce handling costs, crew, control rooms and the need for heat and energy.
Keksintöä ryhdytään seuraavassa lähemmin tarkastelemaan oheisen piirustuksen mukaisen suoritusesimerkin avulla. Piirustus esittää osittain kaaviollisena sivuleikkauskuvantona yhtä keksinnön mukaista laitteistoa.The invention will now be examined in more detail by means of an exemplary embodiment according to the accompanying drawing. The drawing shows a partially schematic side sectional view of one apparatus according to the invention.
Esipuhdistettu (stand. Sa 2,5 SFS) teräs 2 kulkeutuu vapaasti rullaradalla 1, 1' tai erikoiskelkalla 16, johon teräs on levitetty rullaradan l, 1' leveydeltä. Rullarata l, 1' on invertteriohjattu, ts. portaaton nopeuden säätö on mahdollinen, jolloin teräkset 2 voivat kulkeutua haluttua nopeutta. Terästen 2 lähestyessä avataan sylinteriohjauksella 3 eri-koiskumitetut vetotelat 4, jolloin teräsprofiilit pääsevät telojen 4 väliin. Tämän jälkeen sylinterit 3 puristuvat kiinni ja syntyy tarvittava vetokitka terästen 2 siirtämiseksi 5 maadoitettujen ohjausrajoittimien kautta (maadoitus tarvitaan pulveriautomatiikan vuoksi) esikuumennusuuniin 6, joka on joko kaasu-, öljy- tai induktiotoimintoinen. Tarvittavan lämpötehon tulee olla riittävän suuri, jotta ohikulkeva teräs kuumenee helposti n. 250*C:n lämpötilaan ajettaessa nopeudella 0,5...5 m/min. Lämpötila on säädettävissä portaattomasti halutuille nopeuksille.The pre-cleaned (stand. Sa 2.5 SFS) steel 2 travels freely on the roller track 1, 1 'or on a special carriage 16, to which the steel is applied across the width of the roller track 1, 1'. The roller track 1, 1 'is inverter controlled, i.e. stepless speed control is possible, whereby the steels 2 can travel at the desired speed. As the steels 2 approach, the differently rubberized traction rollers 4 are opened by means of a cylinder guide 3, whereby the steel profiles get between the rollers 4. The cylinders 3 are then compressed and the necessary tensile friction is generated to move the steels 2 through the grounded control stops (grounding is required due to powder automation) in a preheating furnace 6 which is either gas, oil or induction operated. The required heat output must be high enough so that the passing steel can easily heat up to a temperature of approx. 250 * C when driving at a speed of 0.5 ... 5 m / min. The temperature is infinitely adjustable to the desired speeds.
Esikuumennusuunin 6 jälkeen rullarata 1, 1' päättyy viimeiseen rullaan 1’, jonka jälkeen teräkset 2 syöttösuunnassa kulkevat vailla tukea vapaasti riippuen.After the preheating furnace 6, the roller track 1, 1 'ends at the last roller 1', after which the steels 2 run freely in the feed direction, depending on the support.
4 840304,84030
Esikuumennetut teräkset 2 siirtyvät rullaradan 1, 1' suuntaisesti nyt pinnoituskammioon 7, jossa varsinainen jauhe-pinnoitus tapahtuu täysin automaattisesti toimivien jauhepin-noituspistoolisarjojen avulla. Jauhemääriä voidaan säätää pneumaattisesti sekä pistoolien määrää muuttamalla, jotta haluttu standardien määrittämä pinnoitekalvon vahvuus saavutetaan. Saatava kalvonvahvuus voi olla 60...1000 pm yhdellä ruiskutuksella.The preheated steels 2 now move parallel to the roller track 1, 1 'to the coating chamber 7, where the actual powder coating takes place by means of fully automatic powder coating gun sets. Powder levels can be adjusted pneumatically as well as by changing the number of guns to achieve the desired coating film strength specified by the standards. The available film thickness can be 60 ... 1000 pm with one spray.
Sintrausuuni 9, 10 on prosessin tärkeä osa, sillä tässä uunissa tapahtuu vapaasti roikkuvien pinnoitettujen terästen 2 valmiiksi sintraantuminen n. 60...120 sekunnissa, jolloin nopeat jauheet pystyvät sintTaantumaan täydellisesti muodostaen yhtenäisen tiiviin kalvon.The sintering furnace 9, 10 is an important part of the process, since in this furnace the free-hanging coated steels 2 are pre-sintered in about 60 ... 120 seconds, whereby the fast powders are able to sinter completely, forming a uniform dense film.
Laitteisto käsittää edelleen pystysuuntaisesti pneumaattisy-1interiohjatun märkätelan 12, johon roikkuva teräs 2 ensi kerran koskettaa saaden vesisuihkun pintaansa. Samalla sylinterit 11 nostavat tuotteen 2 uudelleen toisen rullaradan 16 muodostamalle työstötasolle. Viitenumerolla 13 on kuvattu suuritehoista kastelusuutinjärjestelmää, jolla saadaan pinnoitetun teräksen lämpötila laskemaan n. 50 ...80eC:een, jotta se kestäisi erikoiskumitettujen, vesijäähdytettyjen vetotelojen 14 kitkan ja paineen. Myös telat 14 ovat pneumaattisesti ohjatut (17). valmis pinnoitettu ja jäähdytetty teräs 2 kulkeutuu tarkastuslaitteiston 15 läpi, jossa todetaan pinnoitteen virheettömyys. Tämän jälkeen valmis tuote siirtyy pakkaus- ja niputuslinjalle.The apparatus further comprises a vertically pneumatically controlled wet roller 12, to which the suspended steel 2 first contacts, obtaining a jet of water on its surface. At the same time, the cylinders 11 again raise the product 2 to the machining plane formed by the second roller track 16. Reference numeral 13 describes a high-performance irrigation nozzle system for lowering the temperature of coated steel to about 50 to 80 ° C to withstand the friction and pressure of specially rubberized, water-cooled drive rollers 14. The rollers 14 are also pneumatically guided (17). the finished coated and cooled steel 2 passes through an inspection apparatus 15 where it is established that the coating is free from defects. The finished product then moves to the packaging and bundling line.
Sähköisestä ohjauspöydästä 8 voi yksi henkilö vaivattomasti ohjata kaikkia koneentoimintoja.From the electronic control table 8, one person can easily control all machine functions.
