Mitengo yochokera pa laser kudula nthawi yokha kungachititse kuti malamulo kupanga, komanso kungakhale ntchito yotaya kupanga, makamaka pamene m'mphepete mwa pepala zitsulo wopanga ndi otsika.
Zikafika popereka makampani opanga zida zamakina, nthawi zambiri timalankhula za kupanga kwa zida zamakina. Kodi nayitrogeni amadula bwanji chitsulo theka la inchi? Kodi kuboola kumatenga nthawi yayitali bwanji? Mtengo wothamanga? Tiyeni tichitepo phunziro la nthawi ndikuwona momwe nthawi yakupha imawonekera! Ngakhale izi ndi zoyambira zabwino, kodi ndizosintha zomwe tiyenera kuziganizira tikamaganizira za njira yopambana?
Uptime ndiyofunikira pakumanga bizinesi yabwino ya laser, koma tiyenera kuganizira zambiri kuposa momwe zimatengera nthawi yayitali kuti tichepetse ntchito. Kupereka kokhazikika pakuchepetsa nthawi kumatha kuswa mtima wanu, makamaka ngati phindu lili laling'ono.
Kuti tipeze ndalama zilizonse zobisika pakudula kwa laser, tiyenera kuyang'ana kugwiritsa ntchito ntchito, nthawi yofikira pamakina, kusasinthika kwanthawi yotsogolera ndi gawo lamtundu, kukonzanso kulikonse komanso kugwiritsa ntchito zinthu. Nthawi zambiri, mitengo yazigawo imagwera m'magulu atatu: mtengo wa zida, ndalama zogwirira ntchito (monga zinthu zogulidwa kapena gasi wothandizira), ndi ntchito. Kuchokera apa, ndalama zitha kugawidwa mwatsatanetsatane (onani Chithunzi 1).
Tikamawerengera mtengo wa ntchito kapena mtengo wa gawo, zinthu zonse zomwe zili mu chithunzi 1 zidzakhala gawo la mtengo wonse. Zinthu zimasokonekera pang'ono tikamawerengera ndalama mugawo limodzi popanda kuwerengera moyenera momwe zimakhudzira mtengo wagawo lina.
Lingaliro la kupanga zinthu zambiri silingalimbikitse aliyense, koma tiyenera kuyesa mapindu ake ndi malingaliro ena. Powerengera mtengo wa gawo, timapeza kuti nthawi zambiri, zinthuzo zimatenga gawo lalikulu.
Kuti tipindule kwambiri ndi zinthuzi, titha kugwiritsa ntchito njira monga Collinear Cutting (CLC). CLC imapulumutsa zinthu ndi nthawi yodula, monga mbali ziwiri za gawolo zimapangidwira nthawi imodzi ndi kudula kumodzi. Koma njira imeneyi ili ndi zofooka zina. Zimadalira kwambiri geometry. Mulimonse momwe zingakhalire, tizigawo ting'onoting'ono tomwe timadumphadumpha tifunika kuphatikizidwa kuti zitsimikizire kukhazikika, ndipo wina akuyenera kuziduladula ndikuzichotsa. Zimawonjezera nthawi ndi ntchito zomwe sizibwera kwaulere.
Kupatukana kwa magawo kumakhala kovuta makamaka pogwira ntchito ndi zida zokulirapo, ndipo ukadaulo wodula laser umathandizira kupanga zilembo za "nano" ndi makulidwe opitilira theka la makulidwe a odulidwawo. Kuzipanga sikumakhudza nthawi yothamanga chifukwa matabwa amakhalabe odulidwa; mutatha kupanga ma tabo, palibe chifukwa chobwezeretsanso zipangizo (onani mkuyu 2). Njira zoterezi zimagwira ntchito pamakina ena okha. Komabe, ichi ndi chitsanzo chimodzi chabe cha kupita patsogolo kwaposachedwapa komwe sikulinso kokha kuchedwetsa zinthu.
Apanso, CLC imadalira kwambiri geometry, kotero nthawi zambiri timayang'ana kuchepetsa kukula kwa ukonde mu chisa m'malo mozimiririka kwathunthu. Maukonde akuchepa. Izi zili bwino, koma bwanji ngati gawolo likupendekeka ndikuyambitsa kugunda? Opanga zida zamakina amapereka mayankho osiyanasiyana, koma njira imodzi yopezeka kwa aliyense ndikuwonjezera chotsitsa cha nozzle.
Zomwe zimachitika zaka zingapo zapitazi zakhala zochepetsera mtunda kuchokera ku nozzle kupita ku workpiece. Chifukwa chake ndi chosavuta: ma fiber lasers amathamanga, ndipo ma lasers akulu amathamanga kwambiri. Kuwonjezeka kwakukulu kwa zokolola kumafuna kuwonjezeka kwa nayitrogeni panthawi imodzi. Ma laser amphamvu amawotcha ndikusungunula chitsulo mkati mwa odulidwa mwachangu kwambiri kuposa ma laser a CO2.
M'malo mochedwetsa makina (omwe angakhale osagwirizana), timasintha mphuno kuti igwirizane ndi workpiece. Izi zimawonjezera kuyenda kwa gasi wothandizira kudzera mumphako popanda kuwonjezera kupanikizika. Zikumveka ngati wopambana, kupatula kuti laser ikuyenda mwachangu kwambiri ndipo kupendekera kumakhala vuto.
Chithunzi 1. Magawo atatu ofunika kwambiri omwe amakhudza mtengo wa gawo: zipangizo, ndalama zogwiritsira ntchito (kuphatikizapo zinthu zomwe zimagwiritsidwa ntchito ndi gasi wothandizira), ndi ntchito. Atatuwa adzakhala ndi udindo pa gawo la mtengo wonse.
Ngati pulogalamu yanu ili ndi vuto lakutembenuza gawolo, ndizomveka kusankha njira yodulira yomwe imagwiritsa ntchito cholumikizira chachikulu cha nozzle. Kaya njira iyi ndi yomveka zimadalira kugwiritsa ntchito. Tiyenera kulinganiza kufunikira kwa kukhazikika kwa pulogalamu ndi kuchuluka kwa gasi wothandizira komwe kumabwera ndi kuchuluka kwa kusuntha kwa nozzle.
Njira ina yopewera kudumpha kwa magawo ndikuwonongeka kwa mutu wankhondo, wopangidwa pamanja kapena kugwiritsa ntchito mapulogalamu. Ndipo apanso tikuyang'anizana ndi kusankha. Ntchito zowononga mutu wagawo zimathandizira kudalirika kwa njira, komanso zimawonjezera mtengo wogula komanso mapulogalamu ocheperako.
Njira yomveka kwambiri yopangira kusankha kugwiritsa ntchito ziwonongeko za slug ndikuganizira zosiya. Ngati izi ndi zotheka ndipo sitingathe kukonza bwino kuti tipewe ngozi yomwe ingachitike, tili ndi njira zingapo. Titha kumangirira zigawo ndi zingwe zazing'ono kapena kudula zidutswa zachitsulo ndikuzisiya kuti zigwe bwinobwino.
Ngati mbiri yavuto ndi tsatanetsatane wokha, ndiye kuti tilibe chosankha china, tiyenera kuchiyika. Ngati vutoli likugwirizana ndi mbiri yamkati, ndiye kuti muyenera kufananitsa nthawi ndi mtengo wokonza ndi kuswa chipika chachitsulo.
Tsopano funso limakhala mtengo. Kodi kuwonjezera ma microtag kumapangitsa kuti zikhale zovuta kuchotsa gawo kapena kutsekereza pachisa? Ngati tiwononga mutu wankhondo, tidzakulitsa nthawi yothamanga ya laser. Kodi ndi zotchipa kuwonjezera ntchito zina zolekanitsa, kapena ndizotsika mtengo kuwonjezera nthawi yogwira ntchito pamlingo wa ola la makina? Popeza makinawo amatuluka kwambiri pa ola limodzi, mwina amabwera chifukwa cha zidutswa zingati zomwe ziyenera kudulidwa kukhala tizidutswa tating'ono, zotetezeka.
Ntchito ndizovuta kwambiri ndipo ndizofunikira kuziwongolera poyesa kupikisana pamsika wotsika mtengo. Kudula kwa laser kumafuna ntchito yogwirizana ndi mapulogalamu oyambirira (ngakhale kuti ndalama zimachepetsedwa pa kukonzanso kotsatira) komanso ntchito yokhudzana ndi makina ogwiritsira ntchito. Makinawa akamangokhala ndi makina ambiri, m'pamenenso titha kupeza zochepa kuchokera kumalipiro a ola la ola.
"Automation" mu kudula laser nthawi zambiri amatanthauza kukonza ndi kusanja zinthu, koma ma laser amakono alinso ndi mitundu yambiri yamagetsi. Makina amakono ali ndi kusintha kwa nozzle, kuwongolera kakhalidwe kogwira komanso kuwongolera kuchuluka kwa chakudya. Ndi ndalama, koma kusungidwa kwa ogwira ntchito kungapangitse mtengo wake.
Kulipira kwa ola la makina a laser kumadalira zokolola. Ganizirani makina omwe amatha kusintha nthawi imodzi zomwe zimagwira ntchito ziwiri. Pamenepa, kusintha kuchokera ku masinthidwe awiri kupita kumodzi kumatha kuwirikiza kawiri kuchuluka kwa makina paola lililonse. Pamene makina onse amatulutsa zambiri, timachepetsa kuchuluka kwa makina ofunikira kuti agwire ntchito yofanana. Pochepetsa chiwerengero cha ma lasers, tidzachepetsa ndalama zogwirira ntchito ndi theka.
Zoonadi, ndalamazi zitha kutsika ngati zida zathu zikhala zosadalirika. Ukadaulo wosiyanasiyana wowongolera umathandizira kuti kudula kwa laser kuyende bwino, kuphatikiza kuyang'anira thanzi la makina, macheke a nozzle okha, ndi masensa owala omwe amazindikira dothi pagalasi loteteza la mutu wodula. Masiku ano, titha kugwiritsa ntchito luntha la makina amakono kuti tiwonetse nthawi yomwe yatsala mpaka kukonzanso kwina.
Zonsezi zimathandiza kuti mbali zina za kukonza makina. Kaya tili ndi makina okhala ndi luso limeneli kapena timasunga zipangizo monga zachikale (ntchito zolimba ndi maganizo abwino), tiyenera kuonetsetsa kuti ntchito yokonza ikutha bwino komanso panthawi yake.
Chithunzi 2. Kupita patsogolo kwa laser kudula kumangoyang'ana pa chithunzi chachikulu, osati kuthamanga kokha. Mwachitsanzo, njira imeneyi ya nanobonding (kulumikiza workpieces awiri odulidwa pamodzi mzere wamba) amathandizira kulekana kwa mbali zokhuthala.
Chifukwa chake ndi chosavuta: makina ayenera kukhala ogwiritsidwa ntchito kwambiri kuti asunge zida zonse zogwira mtima (OEE): kupezeka x zokolola x khalidwe. Kapena, monga tsamba la oee.com limanenera: “[OEE] imatanthauzira kuchuluka kwa nthawi yogwira ntchito yopangira. OEE ya 100% imatanthauza 100% khalidwe (zigawo zabwino zokha), 100% ntchito (ntchito yofulumira kwambiri). ) ndi kupezeka kwa 100% (palibe nthawi yopuma). Kupeza 100% OEE sikutheka nthawi zambiri. Muyezo wamakampani ukuyandikira 60% ngakhale OEE wamba imasiyanasiyana malinga ndi kagwiritsidwe ntchito, kuchuluka kwa makina ndi zovuta zogwirira ntchito. Mulimonse momwe zingakhalire, kuchita bwino kwa OEE ndikoyenera kuyesetsa.
Tangoganizani kuti tikulandira pempho la magawo 25,000 kuchokera kwa kasitomala wamkulu komanso wodziwika bwino. Kuwonetsetsa kuti ntchitoyi ikugwira ntchito bwino ikhoza kukhudza kwambiri kukula kwa kampani yathu. Chifukwa chake timapereka $100,000 ndipo kasitomala amavomereza. Iyi ndi nkhani yabwino. Nkhani yoyipa ndi yakuti mapindu athu ndi ochepa. Chifukwa chake, tiyenera kuonetsetsa mulingo wapamwamba kwambiri wa OEE. Kuti tipeze ndalama, tiyenera kuchita zonse zomwe tingathe kuti tiwonjezere dera la buluu ndikuchepetsa gawo la lalanje pa Chithunzi 3.
Pamene malire ali otsika, zodabwitsa zilizonse zimatha kufooketsa kapena kusokoneza phindu. Kodi mapulogalamu oyipa adzawononga nozzle yanga? Kodi choyezera cholakwika chingawononge galasi langa lachitetezo? Ndili ndi nthawi yosakonzekera ndipo ndimayenera kusokoneza kupanga kuti ndisakonzekere. Kodi izi zikhudza bwanji kupanga?
Kusakonza bwino kapena kusamalidwa bwino kungapangitse kuti chakudya chikuyembekezeka (ndi chakudya chomwe chimagwiritsidwa ntchito powerengera nthawi yonse yokonzekera) kukhala yochepa. Izi zimachepetsa OEE ndikuwonjezera nthawi yonse yopanga - ngakhale popanda kufunika kosokoneza kupanga kuti musinthe magawo a makina. Sanzikanani ndi kupezeka kwagalimoto.
Komanso, kodi zigawo zomwe timapanga zimatumizidwadi kwa makasitomala, kapena zina zimatayidwa mumtsuko wa zinyalala? Zotsatira zoyipa pakuwerengera kwa OEE zitha kupweteka kwambiri.
Kudula mitengo ya laser kumaganiziridwa mwatsatanetsatane kuposa kungolipira nthawi yachindunji ya laser. Zida zamakina zamasiku ano zimapereka njira zambiri zothandizira opanga kuti akwaniritse mawonekedwe apamwamba omwe amafunikira kuti akhalebe opikisana. Kuti tikhalebe opindulitsa, timangofunika kudziwa ndikumvetsetsa ndalama zonse zobisika zomwe timalipira pogulitsa ma widget.
Chithunzi 3 Makamaka tikamagwiritsa ntchito malire owonda kwambiri, tifunika kuchepetsa lalanje ndikukulitsa buluu.
FABRICATOR ndiye magazini otsogola opanga zitsulo ku North America. Magaziniyi imasindikiza nkhani, zolemba zamakono komanso mbiri yakale zomwe zimathandiza opanga kupanga ntchito yawo bwino. FABRICATOR wakhala akutumikira makampani kuyambira 1970.
