Description
Vynález sa týká odstreďovania prebytočného zinku zo závitov matic po ich žiarovom zinkovaní tak, aby zinkovací povlak na závitoch bol rovnoměrný s toleranciou mensou ako + lO^ifrj,The invention relates to the centrifugation of excess zinc from the threads of the nuts after their hot-dip galvanizing so that the zinc coating on the threads is uniform with a tolerance of less than + 10 ^ ifrj,
Doteraz používaný technologický postup pozinkovania matic spočívá v tom, že matice sú volné nasypané v nádobě válcového tvaru z perforovaného plechu, v ktorej sú ponárané do roztaveného zinku. Potom sú pozinkované matice v tejto nádobě přenesené manipulačným zariadenim do odstředivky, kde sa odstredia, pričom prebytočný zinok odstředivou silou odtéká z matic a nádoby von.The hitherto used method of galvanizing nuts is that the nuts are loose poured in a cylindrical container made of perforated sheet, in which they are immersed in molten zinc. Then, the galvanized nuts in the vessel are transferred by a handling device to the centrifuge, where they are centrifuged, with excess zinc flowing out of the nuts and the vessel by centrifugal force.

Nevýhoda tohto postupu je v tom, že osi matic sú k osi otáčania orientované rožne a teda prebytočný zinok neodteká zo všetkých závitov matic rovnako, ale može sa nahromadit v závite matice na miestach, kde sa účinok odstredivej sily nemóže uplatnit, lebo jej účinkom je zinok tlačený do závitu.The disadvantage of this procedure is that the axes of the nuts are oriented towards the axis of rotation and thus the excess zinc does not flow out of all the nut threads equally, but can accumulate in the nut thread at locations where the centrifugal force effect cannot be applied. pushed into the thread.
Vyššie uvedený nedostatok sa odstraňuje sposobom odstředivého odstraňovania prebytočného zinku z matic po ich pozinkovaní podlá vynálezu, podstatou ktorého je, že matice sú pri odstredovaní uložené medzi dvoma súetredenými valcami , ktorých os je zhodná s osou otáčania pri odstřelovaní, pričom osi matic sú v podstatě kolmé na os otáčania.The above drawback is remedied by the method of centrifugal removal of excess zinc from the nuts after their galvanizing according to the invention, the principle being that the nuts are, when centrifuged, positioned between two concentric cylinders whose axis coincides with the axis of rotation during blasting. per axis of rotation.
Odstreďovaním matic v usměrněněj polohe sa dosahuje rovnoměrně jšie odtečenie zinku zo závitov matic ako doterajsími postupmi. Je to sposobené tým, že po závitoch v smere osi matice, je odtekanie zinku pri odstředění presnejšie vymedzené, deje sa po kratšej dráhe jedného závitu s nasledovným odstreknutíftz miest závitov, ktoré sú najbližšie k osi matice.Centrifugation of the nuts in the rectified position results in a more even outflow of zinc from the threads of the nuts than in the prior art. This is due to the fact that after the threads in the direction of the axis of the nut, the zinc run-off during centrifugation is more precisely defined, taking place over a shorter path of one thread with subsequent removal of the threads nearest to the axis of the nut.
Matice pozinkované a odstředěné týmto postupom majú rovnoměrně jšiu hrůbku zinkovéj vrstvy na povrchu závitu, takže ich možno použiť i bez dodatočného prerezávania závitu.Nuts galvanized and centrifuged by this process have a more even depth of zinc layer on the surface of the thread, so that they can be used without additional thread cutting.
Zariadenie pre usměrněné odstreďovanie je znázorněné na priloženom obrázku v pozdížnom řeze osou otáčania.The device for directed spinning is shown in the attached figure in a longitudinal section through the axis of rotation.
Matice 1 určené k pozinkovaniu sú nasypané pomocou odnímatelnej násypky 2 do usmernenej polohy kolmej na os otáčania 3 pri odstredovaní, ktorá je totožná s osou sústredených válcov 3. Sústredené válce 4 a 5 sú ukončené s dnom 6. Násypka 2 je odnímatelná a ulahčuje uloženie matic medzi sústredené válce 4 a 5.The nuts 1 to be galvanized are poured by means of a removable hopper 2 into a directed position perpendicular to the axis of rotation 3 during spinning, which is identical to the axis of the centered rollers 3. The centered rollers 4 and 5 terminate with the bottom 6. The hopper 2 is removable and facilitates between the centered rollers 4 and 5.
Sústredené válce ukončené dnom vytvárajú odstreďovací koš pre usměrněné odstredenie. Toto vyhotovenie je vhodné asi do 100 kg vsádky. Geometrický tvar a otáčky odstreďovanie je vhodné navrhoval tak, ako doteraz.The bottom-centered cylinders form a spinning basket for directed centrifugation. This embodiment is suitable up to about 100 kg batch. Geometric shape and spin speed is suitable designed as before.
Usměrněné odstreďovanie možno využil na odstreďovanie pri pokovovaní aj iným roztaveným kovom ako zinkom. Usměrněné odstreďovanie je tiež možno využil pre iné súčiastky ako matice. Takto je vhodné odstredoval súčiastky s otvorom, od ktorých požadujeme - rovnoměrná vrstvu pokovovacieho materiálu v otvore.Rectified centrifugation can be used for centrifugation by plating with other molten metal than zinc. Rectified centrifugation is also possible for components other than nuts. Thus, it is convenient to centrifuge the parts with the hole we require - a uniform layer of metallization material in the hole.
