Description
Fremgangsmåte ved fremstilling av et riflet og/eller ikke riflet belegg på valser for papirmaskiner ved oppvikling av profilbånd. Procedure for producing a fluted and/or non-fluted coating on rollers for paper machines when winding up profile tape.
Oppfinnelsen vedrører en fremgangsmåte ved fremstilling av et riflet og/eller ikke riflet belegg på en valse for en<p>apirmaskin ved oppvikling av et profilbånd spiralfor-met på en vålsestamme eller en motsvarende hylse for å feste<p>rofilbåndvindingene til hverandre og/eller til valsestammen. The invention relates to a method for producing a grooved and/or non-grooved coating on a roller for a<p>paper machine by winding a spiral-shaped profile strip on a roll stem or a corresponding sleeve to attach the<p>profile strip windings to each other and/ or to the rolling stock.
Oppfinnelsen vedrører altså et belegg på en valseThe invention therefore relates to a coating on a roller
for en papirmaskin, fortrinnsvis et korrosjonsbestandig belegg, som er riflet over hele flaten eller ikke riflet over hele flaten. Alternativt kan belegget ha riflede og ikke riflede par-tier ved siden av hverandre i valsens akselretning. for a paper machine, preferably a corrosion-resistant coating, which is fluted over the entire surface or not fluted over the entire surface. Alternatively, the coating can have fluted and non-fluted parts next to each other in the direction of the roll's axis.
Belegg på valser for papirmaskiner fremstilt ved oppvikling av et kontinuerlig beleggbånd på en vålsestamme eller lignende er tidligere kjent f. eks. gjennom finsk patent nr. 45583 (svarende til kanadisk patent nr. 935.685 og U.S. patent nr. 3.718.959). I denne forbindelse vises også til norsk patent nr (norsk patentsøknad nr. 753331) og en til denne tilsluttet tilleggssøknad. De i disse skrifter beskrevne fremgangsmåter kan med egnede deler benyttes ved fremstillingen av et valsebelegg ifølge foreliggende oppfinnelse. Dessuten vises til finsk patent nr (finsk søknad nr. 761.390). Det i dette patent beskrevne belegg består av flere enn ett beleggbånd. Coatings on rollers for paper machines produced by winding a continuous coating band on a drum head or the like are previously known, e.g. through Finnish Patent No. 45583 (equivalent to Canadian Patent No. 935,685 and U.S. Patent No. 3,718,959). In this connection, reference is also made to Norwegian patent no. (Norwegian patent application no. 753331) and a supplementary application attached to it. The methods described in these documents can, with suitable parts, be used in the production of a roller coating according to the present invention. In addition, reference is made to Finnish patent no (Finnish application no. 761,390). The coating described in this patent consists of more than one coating tape.
Formålet med foreliggende oppfinnelse er å tilveie-bringe en hurtigere og mer sikker fremgangsmåte for å feste( val-sebeleggenésinntil hverandre forløpende vindinger til hverandre og/eller til valsestammen eller et annet motsvarende underlag. The purpose of the present invention is to provide a faster and more secure method for attaching (roll coating) continuous turns to each other and/or to the roll stem or another corresponding substrate.
I forbindelse med en fremgangsmåte ifølge oppfinnelsen kan ved angjeldende innfesting og låsing dessuten utnyttes de løsninger, f. eks. spor-list-forbindelse, som er beskrevet i søkerens tidligere patenter. In connection with a method according to the invention, the relevant fixing and locking solutions can also be utilized, e.g. track-list connection, which is described in the applicant's previous patents.
For å oppnå det ovenfor angitte og øvrige formål er oppfinnelsen i det vesentlige kjennetegnet ved at nevnte innfesting utføres ved sveising med en elektronstråle. In order to achieve the above-mentioned and other purposes, the invention is essentially characterized by said attachment being carried out by welding with an electron beam.
Oppfinnelsen skal i det følgende nærmere beskrives under henvisning til noen på figurene på tegningen viste utfør-elsesformer for oppfinnelsen. Det er dog ikke meningen på noen måte å begrense oppfinnelsen til disse utførelsesformer. In the following, the invention will be described in more detail with reference to some embodiments of the invention shown in the figures in the drawing. However, it is not intended to limit the invention to these embodiments in any way.
Figuren viser skjematisk tre utførelsesformer for fremgangsmåten ifølge oppfinnelsen. The figure schematically shows three embodiments of the method according to the invention.
Det på figuren viste valsebelegg 7 består på i og for seg kjent måte av et profilbånd 3, som er skruelinjeformet opp-viklet på en vålsestamme 9, slik at profilets 3a og 3b osv. sider ligger an mot hverandre. Ifølge figuren er profilet 3 utstyrt med et kantspor, hvorved profilet 3 danner et med et spor 4 utstyrt belegg på valsen. Det er dog klart at oppfinnelsen også kan anvendes på ikke riflede valsebelegg. Herved danner profilbåndets"3 ytre side en glatt flate på valsebelegget 7 og prof-ilbåndets 3 indre side 8 ligger an mot den ytre flate av valsestammen 9 eller en motsvarende hylse. The roller coating 7 shown in the figure consists in a manner known per se of a profile band 3, which is helically wound on a roller stem 9, so that the sides of the profile 3a and 3b etc. abut against each other. According to the figure, the profile 3 is equipped with an edge groove, whereby the profile 3 forms a coating on the roller equipped with a groove 4. It is clear, however, that the invention can also be applied to non-grooved roller coatings. Hereby, the outer side of the profile strip 3 forms a smooth surface on the roller coating 7 and the inner side 8 of the profile strip 3 rests against the outer surface of the roller stem 9 or a corresponding sleeve.
Ifølge figuren har profilbåndet 3 på den ene vertikal-side et spor 6 i lengderetning som opptar en del av den ved sveising tilveiebragte smelte, slik at forbindelsen mellom vind-ingene 3a og 3b ikke blir bærende. According to the figure, the profile band 3 on one vertical side has a groove 6 in the longitudinal direction which takes up part of the melt provided by welding, so that the connection between the windings 3a and 3b does not become load-bearing.
På figuren er med henvisningstallet 2 betegnet en elektronkanon hørende til et elektronstrålesveiseaggregat. Elek-tfonkariorien 2 danner en av et elektrisk felt akselerert kraftig-elektronstråle 1. De på dette måte akselererte elektroner har meget stor bevegelsesenergi og stor'virkningsdybde. Sveiseinn-trengningen er altså stor. Virkningen av en elektronstråle er vesentlig dypere enn virkningen av f. eks. laser- og plåsma-stråler og lysbuer. En annen vesentlig fordel med oppfinnelsen er at elektronstrålen kan konsentreres på et spesielt lite om-råde og at styringen av strålen relativt lett kan automatiseres. In the figure, reference number 2 denotes an electron gun belonging to an electron beam welding unit. The electric current 2 forms a powerful electron beam 1 accelerated by an electric field. The electrons accelerated in this way have very large kinetic energy and a large depth of action. The welding penetration is therefore great. The effect of an electron beam is significantly deeper than the effect of e.g. laser and plasma beams and arcs. Another significant advantage of the invention is that the electron beam can be concentrated on a particularly small area and that the control of the beam can be relatively easily automated.
På figuren vises tre måter å rette elektronstrålen 1 fra elektronkanonen 2 mot sveisestedet. En elektronkanon 2a retter sin elektronstråle la gjennom sporet 4 i valsebelegget 7 til anleggsflaten mellom de ved siden av hverandre forløpende profilvindinger 3a og 3b, hvorved det fremkommer en smal sveisefuge 10a, hvis ende 10a' trenger inn i valsestammen 9. Med en slik sveisefuge 10a, 10a<1>festes profilvindingene både til hverandre og til valsestammen 9. The figure shows three ways to direct the electron beam 1 from the electron gun 2 towards the welding spot. An electron gun 2a directs its electron beam la through the groove 4 in the roller coating 7 to the contact surface between the side-by-side profile windings 3a and 3b, whereby a narrow weld seam 10a appears, the end 10a' of which penetrates into the roll stem 9. With such a weld seam 10a , 10a<1>the profile windings are attached both to each other and to the roller stem 9.
Ifølge figuren retter en elektronkanon 2b sin elektronstråle lb i det vesentlige vinkelrett mot ovenfor beskrevne sveisefuge 10a, hvorved det fremkommer en sveisefuge 10b som fester de ved siden av hverandre løpende profilvindinger til hverandre. Denne sveisefuge 10b kan anvendes sammen med fugen 10a eller istedet for denne. Ifølge figuren retter dessuten en elektronkanon 2c sin elektronstråle lc skrått, slik at det fremkommer en sveisefuge 10c, hvis nedre ende 10c' trenger inn i valsestammen 9. Profilbåndvindingene festes altså både:'.til ' hverandre og til valsestammen 9. According to the figure, an electron gun 2b directs its electron beam lb substantially perpendicular to the welding joint 10a described above, whereby a welding joint 10b is produced which attaches the side-by-side profile windings to each other. This welding joint 10b can be used together with the joint 10a or instead of it. According to the figure, an electron gun 2c also directs its electron beam lc obliquely, so that a welding seam 10c appears, the lower end 10c' of which penetrates into the roll stem 9. The profile tape windings are thus attached both:'.to each other and to the roll stem 9.
De ovenfor beskrevne sveisefuger 10a, 10b, 10c kan anvendes hver for seg eller sammen i egnede kombinasjoner. The welding joints 10a, 10b, 10c described above can be used separately or together in suitable combinations.
Den ovenfor forklarte elektronstrålesveising utføres fordelaktig samtidig som profilbåndet vikles på valsestammen 9. Elektronstrålesveisingen behøver ikke være kontinuerlig, men den" kan også skje periodisk, hvorved elektronkanonen 2 med hensikts-messige tidsmellomrom og/eller på egnede steder avgir en kraftig, sveisende elektronpuls mot profilbåndet 3. Dette kan lett ord-nes ved hjelp av automatisk styring. The above-explained electron beam welding is advantageously carried out at the same time as the profile strip is wound on the roll stem 9. The electron beam welding does not have to be continuous, but it can also take place periodically, whereby the electron gun 2 emits a powerful, welding electron pulse against the profile strip at suitable time intervals and/or at suitable locations 3. This can easily be arranged using automatic control.
For elektronkanonens 2 riktige funksjon er det nød-vendig at det i dens kammer hersker et vakuum i størrelsesorden For the electron gun 2 to function correctly, it is necessary that a vacuum of the order of magnitude prevails in its chamber
-4 -5 10 - 10 torr. Derimot behøver det ikke i elektronkanonens 2 arbeidskammer, altså i det kammer som står i forbindelse med sveisestedet, nødvendigvis herske like stort undertrykk, da man har konstatert at et mindre vakuum er tilstrekkelig i flere til-feller, f. eks. såkalt halvvakuum (10 - 2 ■- 10 -1 torr), eller til og med atmosfæretrykk (760 torr). I det sistnevnte tilfelle må dog arbeidsstykket føres meget nær elektronkanonen. -4 -5 10 - 10 torr. On the other hand, in the working chamber of the electron gun 2, i.e. in the chamber which is in connection with the welding point, there does not necessarily need to be an equal amount of negative pressure, as it has been established that a smaller vacuum is sufficient in several cases, e.g. so-called half-vacuum (10 - 2 ■- 10 -1 torr), or even atmospheric pressure (760 torr). In the latter case, however, the workpiece must be brought very close to the electron gun.
Ettersom elektronstrålesveisingen kan utføres med særlig stor hastighet og ettersom strålen kan rettes automatisk og ifølge program og styres ved hjelp av f. eks. magnetfelt, As the electron beam welding can be carried out at a particularly high speed and as the beam can be directed automatically and according to a program and controlled using e.g. magnetic field,
kan innfestingsmetoden ifølge op<p>finnelsen gjennomføres samtidig som oppviklingen av profilbåndet uten vesentlig å bremse dette arbeidstrinn. the attachment method according to the invention can be carried out at the same time as the winding of the profile tape without significantly slowing down this work step.
Oppfinnelsen er ikke begrenset til de ovenfor bare som eksempler beskrevne utførelsesformer, men oppfinnelsens de-taljer kan variere innenfor rammen av oppfinnelsestanken. The invention is not limited to the embodiments described above only as examples, but the details of the invention may vary within the framework of the inventive idea.
