Pinnoitusmenetelmä ja -laiteCoating method and apparatus

Keksinnön kohteena on pinnoitusmenetelmä, jossa pinnoitettava kappale upotetaan altaassa olevaan kylpyyn, pidetään pinnoitustyökalua pysyvästi 5 altaassa ja pinnoitettava kappale asetetaan työkalun yhteyteen vasta kylvyn sisällä. Keksinnön kohteena on myös pinnoituslaite, johon kuuluu nestekylvyn sisältävä pinnoitusallas ja nestekylpyyn upotettu pinnoitustyökalu, joka on pysyvästi altaassa.The invention relates to a coating method in which the object to be coated is immersed in a bath in the basin, the coating tool is held permanently in the basin and the object to be coated is only placed in contact with the tool inside the bath. The invention also relates to a coating device comprising a coating bath containing a liquid bath and a coating tool immersed in a liquid bath which is permanently in the pool.

10 Keksinnön erityinen käyttösovellutus on kappaleiden sisäpuolinen pinnoittaminen kromipinnoitteella.A particular application of the invention is the chromium plating of articles internally.

Pinnoitettaessa kappaleita elektrolyyttisesti kromilla, on pinnoitusaika pitkä, mikä johtuu usein tarvittavasta paksusta pinnoitekerroksesta ja siitä, että 15 elektrolyysissä kromi pelkistyy huonosti ja vaatii paljon sähköä. Tämä edellyttää voimakkaita sähkökenttiä, jotka on voitava ohjata haluttuun kohtaan halutulla voimakkuudella.When electrolytically coating articles with chromium, the coating time is long, which is due to the often required thick coating layer and the poor electrolysis of chromium and a high electricity requirement. This requires strong electric fields which must be able to be applied to the desired position at the desired intensity.

• Nykyisin käytössä olevissa menetelmissä pinnoitustyökalu, kuten anodilevyt, ; 20 sähkökentän varjostimet yms. kiinnitetään pinnoitettavaan kappaleeseen kyl- : l vyn ulkopuolella ja upotetaan yhdessä pinnoitettavan kappaleen kanssa kyl- ·' ·’ pyyn. Anodit ovat usein likaisia ja vaikeasti käsiteltäviä.• In current methods, a coating tool such as anode plates; 20 electric field shades and the like are attached to the object to be coated outside the bath and immersed with the object to be coated in the bath. Anodes are often dirty and difficult to handle.

·’ Keksijäntodistuksesta SU 509664 tunnetaan alussa mainittua tyyppiä oleva 25 menetelmä ja laite. Tässä tunnetussa ratkaisussa pinnoitustyökaluna toimiva ·' ‘ anodi on kiinnitetty altaassa olevan asennustangon ympärille. Sähkövirta tälle anodille on tuotava erityisellä kosketinjärjestelyllä, joka on avattavassa ja : suljettavassa kannessa.The inventor's certificate SU 509664 discloses a method and apparatus of the type mentioned above. In this known solution, the · '' anode, which acts as a coating tool, is mounted around a mounting bar in the pool. Electricity for this anode must be provided by a special contact arrangement which is in a flip-open and: closable cover.

•.;. 30 Keksinnön tarkoituksena on parantaa tunnettuja menetelmiä ja laitteita siten, 1... että pinnoitustyökalujen käsittely olennaisesti helpottuu ja siten tuotanto te hostuu.•.;. The object of the invention is to improve the known methods and devices in such a way that the handling of the coating tools is substantially facilitated and thus the production is improved.

2 114811 Tämä tarkoitus saavutetaan keksinnöllä oheisissa patenttivaatimuksissa esitettyjen tunnusmerkkien perusteella. Patenttivaatimuksessa 1 on esitetty menetelmän tunnusomaiset piirteet ja patenttivaatimuksessa 4 on esitetty laitteen tunnusomaiset piirteet.This object is achieved by the invention on the basis of the features set forth in the appended claims. Claim 1 describes the process features and claim 4 the device features.

Kun keksinnön mukaisessa ratkaisussa työkalu on pysyvästi altaassa ja pinnoitettava kappale asetetaan työkalun yhteyteen kylvyn sisällä, tarvitsee ainoastaan pinnoitettava kappale vaihtaa. Työkalun kiinnityksiä tai sähkön tai kemikaalien syöttöä työkalulle ei tarvitse purkaa ja uudelleen asentaa kappa-10 leita vaihdettaessa.When, in the solution of the invention, the tool is permanently in the pool and the object to be coated is placed in contact with the tool inside the bath, all that is needed is to replace the object to be coated. There is no need to disassemble the tool mounts or power or chemical supply to the tool when replacing kappa-10s.

Seuraavassa keksinnön yhtä suoritusesimerkkiä selostetaan lähemmin viittaamalla oheiseen piirustukseen, joka esittää leikkausta pinnoitusaltaasta pinnoituslaitteineen, joilla keksinnön mukainen menetelmä voidaan toteuttaa.In the following, one embodiment of the invention will be described in more detail with reference to the accompanying drawing, which shows a section of a coating pan with coating means by which the method of the invention can be implemented.

Seuraavassa keksintöä selostetaan sovellettuna elektrolyyttiseen pinnoitukseen, mutta sitä voidaan soveltaa yleisemminkin hydrometallurgiassa, jolloin altaaseen 1 järjestetty putki tai kanava palvelee kemikaalien syöttöä tai kun • ·; suoritetaan ilman sähköä esim. tekninen nikkelöinti pelkistymisen avulla halu- : 20 tuille pinnoille.In the following, the invention will be described as applied to electrolytic plating, but may be more generally applied in hydrometallurgy, wherein the pipe or duct provided in the basin 1 serves to supply chemicals or when; is carried out without electricity, for example by means of technical nickel-plating by reduction to desired surfaces.

·’. ’·* Erityisen edullisesti keksintö soveltuu kuitenkin elektrolyyttisesti kromilla suo- ·'. : ritettavaan pinnoitukseen (kovakromaus).· '. However, it is particularly preferred that the invention be electrolytically protected with chromium. : for rolling coating (hard chrome plating).

• « 25 Esitetyssä suoritusesimerkissä pinnoitusallas 1 on esim. muovilla pinnoitettu ·’ ’ teräsallas, jossa on elektrolyysinestettä 2. Altaassa 1 on yksi tai useampi al taan pohjan lävistävä pystysuuntainen putki 3, jonka yläpää ulottuu neste- » : pinnan yläpuolelle. Putkeen 3 on sijoitettu virtakisko 4, joka on kiinnitetty ..: putken 3 yläpään varassa lepäävään levyyn 6, joka on hyvin sähköä johtavaa ··*·*’: 30 ainetta, esim. kuparia. Levyyn 6 on ripustettu anodilevyt 5, jotka asettuvat putkea 3 ympäröiväksi kehäksi. Putken 3 kautta voidaan järjestää virranvienti 3 114811 myös katodille. Tällaista järjestelyä voidaan käyttää edullisesti prosessiteollisuuden putkimaisten kappaleiden sisäpuoliseen pinnoitukseen.In the exemplary embodiment, the coating pan 1 is, for example, a plastic-coated steel pan with an electrolytic fluid 2. The pan 1 has one or more vertical tubes 3 penetrating the bottom of the pan, the upper end of which extends above the liquid surface. In the tube 3 is placed a busbar 4, which is attached to a plate 6, which is very electrically conductive ·· * · * ': 30 substances, e.g. copper, resting on the upper end of the tube 3. The plate 6 is fitted with anode plates 5 which are positioned around the periphery of the tube 3. Power supply 3 114811 can also be provided via cathode 3 to the cathode. Such an arrangement can advantageously be used for the internal coating of tubular bodies in the process industry.

Pinnoitettava kappale 7 upotetaan altaaseen 1 putken 3 yläpään varaan tuet-5 tavalla ripustimella 8, jossa on nostokorvake 8a. Viitenumerolla 9 on merkitty kappaleen 7 sisäpintaan saostettavaa pinnoitetta.The body 7 to be coated is submerged in the basin 1 on the upper end of the pipe 3 in a support-5 manner by means of a hanger 8 having a lifting lug 8a. Reference numeral 9 designates the coating to be deposited on the inner surface of body 7.

Anodien 5 lisäksi pinnoitustyökaluun kuuluu usein virran vaijostimia, joita sijoitetaan esim. kappaleen 7 päätyjen läheisyyteen. Myös tällaiset virran var-10 jostimet tai muut pinnoitustyökaluun kuuluvat laiteosat voidaan tukea tai ripustaa putken 3 varaan siten, että ne ovat pysyvästi altaassa niin kauan kuin samanlaisia kappaleita pinnoitetaan. Kun pinnoitettava kappale vaihtuu, vaihdetaan tai uudelleen asetellaan pinnoitustyökalut pinnoitettavan kappaleen mukaisesti.In addition to the anodes 5, the coating tool often includes current shields, which are located e.g. near the ends of paragraph 7. Also, such power-lifters or other parts of the coating tool may be supported or suspended on the tube 3 so that they remain permanently in the pool as long as similar pieces are coated. When the part to be coated is changed, the coating tools are replaced or re-positioned according to the part to be coated.

Elektrolyysinesteen läpäisevien putkien 3 lukumäärä, sijainti ja muoto voi monin tavoin vaihdella. Tyypillisesti putket 3 kuitenkin sijaitsevat symmetrisesti altaassa 1, ovat pystysuorassa ja läpäisevät altaan pohjan.The number, location and shape of the tubes 3 passing through the electrolytic fluid can vary in many ways. Typically, however, the tubes 3 are symmetrically located in the basin 1, are vertical and pass through the bottom of the basin.

20 Seuraavassa vielä lyhyt luettelo keksintöön liittyvistä olennaisista piirteistä: 1. Pinnoitustyökalut ovat kiinteästi altaassa (konventionaalinen menetelmä: : työkalu nostetaan pinnoitettavan kappaleen mukana altaaseen) : 2.
