Ngati mukuyang'ana makina aliwonse omwe angayende ndi koyilo, ndiye kuti palibe kukayikira kuti mukufunikira chotsegula kapena chotsegula.
Kuyika ndalama pazida zazikulu ndi ntchito yomwe imafuna kuti muganizire zinthu zambiri ndi ntchito. Kodi mukufuna makina oti akwaniritse zomwe akupanga pano, kapena mukufuna kuyikapo ndalama m'mibadwo yotsatira? Awa ndi mafunso omwe eni sitolo amadzifunsa nthawi zonse akamagula makina opangira mipukutu. Komabe, kafukufuku wokhudza ma uncoilers sanasamalidwe kwenikweni.
Ngati mukuyang'ana makina aliwonse omwe angayende ndi koyilo, ndiye kuti palibe kukayikira kuti mukufunikira uncoiler (kapena nthawi zina amatchedwa uncoiler). Ziribe kanthu kuti muli ndi mpukutu wopangira, kupondaponda kapena kudula mzere wopangira, mukufunikira chotsegula kuti mumasulire koyiloyo pa sitepe yotsatira; palibe njira ina yochitira izo. Kuwonetsetsa kuti decoiler ikukumana ndi msonkhano wanu ndi zosowa za polojekiti ndikofunikira kuti musunge mawonekedwe a makina opangira mipukutu, chifukwa popanda zinthuzo, makinawo sangagwire ntchito.
M'zaka 30 zapitazi, makampani asintha kwambiri, koma uncoiler nthawi zonse amapangidwa molingana ndi zomwe makampani opanga zitsulo amapanga. Zaka makumi atatu zapitazo, muyeso wakunja wakunja (OD) wamakoyilo achitsulo anali mainchesi 48. Pamene digiri ya makonda a makina akukwera kwambiri, ndipo ntchitoyo imafuna zosankha zosiyanasiyana, kusinthasintha kwa koyilo yachitsulo ndi mainchesi 60, kenako mainchesi 72. Masiku ano, opanga nthawi zina amagwiritsa ntchito makoyilo akuluakulu kuposa mainchesi 84. mu. Kolo. Chifukwa chake, decoiler iyenera kusinthidwa kuti igwirizane ndi kukula kwakunja kwa koyilo.
Uncoilers amagwiritsidwa ntchito kwambiri pamakampani ogubuduza. Masiku ano makina opangira mpukutu ali ndi zinthu zambiri komanso ntchito zambiri kuposa zomwe zidalipo kale. Mwachitsanzo, zaka 30 zapitazo, liwiro la mpheroyo linali 50 mapazi pamphindi (FPM). Tsopano amatha kuthamanga mpaka 500 FPM. Kusintha kumeneku pakupanga mpukutu kwathandiziranso kuthekera komanso mitundu yosiyanasiyana ya zosankha za decoiler. Sikokwanira kusankha decoiler yokhazikika. Zinthu zambiri ndi ntchito ziyenera kuganiziridwa kuti zitsimikizire kuti zosowa za msonkhanowo zikukwaniritsidwa.
Wopanga ma decoiler amapereka zosankha zingapo kuti awonetsetse kuti njira yopangira mipukutuyo ikwaniritsidwe. Masiku ano decoiler akulemera mapaundi 1,000. Kupitilira mapaundi 60,000. Posankha decoiler, chonde kumbukirani izi:
Muyeneranso kuganizira mtundu wa pulojekiti yomwe mukugwira ntchito ndi zipangizo zomwe mudzagwiritse ntchito.
Zonse zimadalira zomwe mukufuna kuthamanga pa mphero yopukutira, kuphatikizapo ngati koyiloyo idakutidwa kale, galvanized kapena chitsulo chosapanga dzimbiri. Izi zimatsimikizira zomwe mukufuna ma decoiler.
Mwachitsanzo, decoiler wamba ndi decoiler yokhala ndi malekezero amodzi, koma kukhala ndi decoiler yokhala ndi malekezero awiri kumatha kuchepetsa nthawi yodikirira yogwira zinthu. Ndi zopota ziwiri, woyendetsa amatha kukweza koyilo yachiwiri pamakina ndikuyikonza pakafunika. Izi ndizofunikira makamaka ngati wogwiritsa ntchito nthawi zonse akufunika kusintha koyiloyo.
Opanga nthawi zambiri samazindikira momwe chopangiracho chimagwirira ntchito mpaka atazindikira kuti wochotsayo amatha kuchita maopaleshoni asanu ndi limodzi kapena asanu ndi atatu kapena kupitilira apo patsiku. Pambuyo pokonzekera koyilo yachiwiri pamakina ndikudikirira makinawo, palibe chifukwa chokweza koyilo yoyamba ndi forklift kapena crane nthawi yomweyo. Decoiler imagwira ntchito yofunika kwambiri popanga mipukutu, makamaka pakupanga zinthu zambiri, pomwe makina amatha kutengera maola asanu ndi atatu kuti apange magawo.
Mukayika ndalama mu decoiler, ndikofunikira kumvetsetsa zomwe zikuchitika komanso mawonekedwe ake. Komabe, m’pofunikanso kuganizira mmene makinawo adzagwiritsidwire ntchito m’tsogolo komanso ntchito zimene zidzachitike m’tsogolo pa mpheroyo. Izi ndizinthu zonse zomwe ziyenera kuganiziridwa moyenerera, ndipo zimathandizadi kudziwa decoiler yoyenera.
Galimoto ya koyilo imathandizira kukweza koyilo pa mandrel osadikirira kuti crane kapena forklift ithe.
Kusankha mandrel wokulirapo kumatanthauza kuti mutha kuyendetsa koyilo yaying'ono pamakina. Chifukwa chake, ngati mungasankhe mainchesi 24. Spindle, mutha kuchita ntchito zina zilizonse. Ngati mukufuna kudumpha mpaka mainchesi 36. Njira, ndiye kuti muyenera kuyika ndalama mu decoiler yayikulu. Ndikofunika kuyang'ana mwayi m'tsogolomu.
Pamene makoyilo akukulirakulira, chitetezo ndiye vuto lalikulu mumsonkhanowu. Decoiler ili ndi zigawo zazikulu, zoyenda mwachangu, kotero ogwiritsira ntchito ayenera kuphunzitsidwa kugwiritsa ntchito makina ndikuwongolera koyenera.
Masiku ano, ma coil amatha kuchoka pa 33 mpaka 250 kilogalamu pa mainchesi apakati, ndipo ma uncoilers asinthidwa kuti akwaniritse zofunikira za mphamvu zokolola. Zozungulira zolemera zimakhala zovuta kwambiri pachitetezo, makamaka podula malamba. Makinawa amaphatikiza mkono woponderezedwa ndi chodzigudubuza chotchinga kuti awonetsetse kuti mpukutuwo umangomasulidwa ngati pakufunika. Makinawa amathanso kuphatikizirapo choyendetsa mapepala ndi chosinthira chakumbali kuti chithandizire pakati pa intaneti panjira yotsatira.
Pamene kulemera kwa koyilo ukuwonjezeka, zimakhala zovuta kuti pamanja kuwonjezera mandrel. Malo ochitira msonkhano akamasuntha woyendetsa kuchokera ku decoiler kupita kumadera ena a msonkhano pazifukwa zachitetezo, ma spindle okulitsidwa ndi ma hydraulically ndi kuthekera kozungulira nthawi zambiri kumafunika. Chotsitsa chododometsa chitha kuwonjezeredwa kuti muchepetse kugwiritsidwa ntchito molakwika kwa kuzungulira kwa decoiler.
Malingana ndi ndondomeko ndi liwiro, zina zotetezera zingafunike. Zinthuzi ndi monga chogwirira chakunja chotchinga kuti koyilo isagwe, makina owunikira ma coil akunja ndi RPM, komanso makina apadera amabuleki monga mabuleki oziziritsidwa ndi madzi pamapaipi othamanga kwambiri. Izi ndi zofunika kwambiri ndipo zimathandiza kuonetsetsa kuti kugubuduza kukayima, decoiler imayimanso.
Ngati mumagwira ntchito ndi zida zamitundu yambiri, mutha kugwiritsa ntchito decoiler yapadera yomwe imapereka ma mandrel asanu, zomwe zikutanthauza kuti mutha kuyika ma coil asanu pamakina nthawi imodzi. Wogwiritsa ntchito amatha kupanga mazana amtundu umodzi ndikusinthira ku mtundu wachiwiri osataya nthawi kutsitsa koyilo ndikusintha.
Mbali ina ya galimoto koyilo ndi kuti kumathandiza katundu koyilo pa mandrel. Izi zimatsimikizira kuti woyendetsa sayenera kudikirira kuti crane kapena forklift ikweze.
Ndikofunikira kuwononga nthawi ndikufufuza zosankha zosiyanasiyana zomwe zilipo pa decoiler. Ndi mandrel osinthika kuti agwirizane ndi ma coil amitundu yosiyanasiyana yamkati, ndi mitundu ingapo yamitundu yosiyanasiyana ya coil backplane, muyenera kuganizira zinthu zambiri kuti mupeze zoyenera. Kulemba zolemba zamakono komanso zomwe zingatheke kukuthandizani kudziwa zofunikira.
Makina opangira gudumu, monga makina ena aliwonse, amapeza ndalama pokhapokha akuyenda. Kusankha decoiler yoyenera pazosowa zanu zaposachedwa komanso zamtsogolo kumathandizira makina anu opangira roll kuti aziyenda bwino komanso mosatekeseka.

Tsopano popeza tili ndi CASL, tikuyenera kutsimikizira ngati mukuvomera kulandira zosintha kudzera pa imelo. Ndi kulondola uko?
Pokhala ndi mwayi wofikira ku mtundu wa digito wa zitsulo zaku Canada, zida zamakampani zamtengo wapatali tsopano zikupezeka mosavuta.
Tsopano, ndi mwayi wokwanira ku Canadian Manufacturing and Welding Digital Edition, chuma chamtengo wapatali chamakampani chikhoza kupezeka mosavuta.
Laser ya HD-FS 3015 2kW muchipinda chathu chowonetsera yayesedwa! Chonde dziwani kuti nthawi zina, timagwiritsa ntchito mpweya wa msonkhano mu Access Machinery kudula zitsulo ndi aloyi, ngakhale kudula khalidwe la zitsulo izi ndi aloyi si zabwino monga asafe. Tinakambirana za momwe pafupifupi makampani onse opanga zinthu amapangira mpweya wa msonkhano womwe ungagwiritsidwe ntchito kuchepetsa kwambiri ndalama zogwiritsira ntchito laser ndikupeza mwayi wopikisana.
