Amaxabiso asekelwe kwixesha lokusika i-laser yedwa kunokukhokelela kwimiyalelo yokuvelisa, kodwa kunokuba ngumsebenzi wokulahlekelwa, ngakumbi xa imida yomenzi we-sheet metal iphantsi.
Xa kuziwa ekuboneleleni kwishishini lesixhobo somatshini, sihlala sithetha malunga nemveliso yezixhobo zoomatshini. Ikhawuleza kangakanani initrogen ukusika intsimbi yesiqingatha se-intshi? Kuthatha ixesha elingakanani ukugqobhoza? Isantya sokukhawulezisa? Masenze uphononongo lwexesha kwaye sibone ukuba linjani ixesha lokubulawa! Ngelixa ezi zingamanqaku amahle okuqalisa, ngaba ngokwenene ziguquguqukayo ekufuneka siziqwalasele xa sicinga ngefomula yempumelelo?
Ixesha lokuphumla libalulekile ekwakheni ishishini le-laser elungileyo, kodwa kufuneka sicinge malunga nokuba kuthatha ixesha elingakanani ukunciphisa umsebenzi. Umnikelo osekelwe kuphela ekunciphiseni ixesha unokukophula intliziyo yakho, ngakumbi ukuba inzuzo incinci.
Ukutyhila naziphi na iindleko ezinokubakho ezifihliweyo ekusikeni kwe-laser, kufuneka sijonge ukusetyenziswa kwabasebenzi, ixesha lomatshini, ukungaguquguquki ngexesha lokukhokela kunye nomgangatho wenxalenye, nakuphi na ukuphinda kusetyenzwe kunye nokusetyenziswa kwezinto eziphathekayo. Ngokubanzi, iindleko zenxalenye ziwela kwiindidi ezintathu: iindleko zezixhobo, iindleko zabasebenzi (njengezinto ezithengiweyo okanye igesi eyongezelelweyo esetyenzisiweyo), kunye nomsebenzi. Ukusuka apha, iindleko zinokwahlulwa zibe ziinkcukacha ezithe vetshe (jonga uMfanekiso 1).
Xa sibala iindleko zomsebenzi okanye iindleko zenxalenye, zonke izinto ezikumfanekiso 1 ziya kuba yinxalenye yeendleko zizonke. Izinto zifumana ukudideka kancinci xa sijonga iindleko kwikholamu enye ngaphandle kokubala ngokufanelekileyo impembelelo kwiindleko kwenye ikholamu.
Umbono wokwenza uninzi lwemathiriyeli unokungakhuthazi nabani na, kodwa kufuneka silinganise iingenelo zayo ngokuthelekisa nezinye izinto. Xa ubala iindleko zenxalenye, sifumanisa ukuba kwiimeko ezininzi, izinto eziphathekayo zithatha inxalenye enkulu.
Ukufumana okuninzi kwizinto eziphathekayo, sinokusebenzisa izicwangciso ezifana neCollinear Cutting (CLC). I-CLC igcina izinto eziphathekayo kunye nexesha lokusika, njengoko imiphetho emibini yenxalenye yenziwa ngexesha elinye kunye nokusika enye. Kodwa obu buchule bunemida ethile. Ixhomekeke kakhulu kwijometri. Kuyo nayiphi na imeko, iindawo ezincinci ezityekele ekugqityweni kufuneka zidityaniswe ukuze kuqinisekiswe uzinzo lwenkqubo, kwaye umntu kufuneka awahlukanise la malungu kwaye mhlawumbi angawasusa. Yongeza ixesha kunye nomsebenzi ongezi simahla.
Ukwahlula kwamacandelo kunzima ngakumbi xa usebenza ngezinto ezityebileyo, kwaye iteknoloji yokusika i-laser inceda ukudala iilebula "ze-nano" ezinobunzima obungaphezu kwesiqingatha sobunzima bokusika. Ukuyidala akuchaphazeli ixesha lokubaleka kuba imiqadi ihleli ekusikeni; emva kokudala iithebhu, akukho mfuneko yokuphinda ufake izinto (jonga umfanekiso 2). Ezo ndlela zisebenza kuphela koomatshini abathile. Noko ke, lo ngumzekelo nje omnye wenkqubela yakutshanje engasapheleliyo ekuthobeni izinto.
Kwakhona, i-CLC ixhomekeke kakhulu kwijometri, ngoko ke kwiimeko ezininzi sijonge ukunciphisa ububanzi bewebhu kwindlwane kunokuba siyenze inyamalale ngokupheleleyo. Uthungelwano luyacutheka. Oku kulungile, kodwa kuthekani ukuba inxalenye iyathambeka kwaye ibangele ukungqubana? Abavelisi bezixhobo zoomatshini babonelela ngezisombululo ezahlukeneyo, kodwa enye indlela ekhoyo kuye wonke umntu yongeza i-nozzle offset.
Umkhwa weminyaka embalwa edlulileyo kukunciphisa umgama ukusuka kwi-nozzle ukuya kwindawo yokusebenza. Isizathu silula: iilaser zefiber ziyakhawuleza, kwaye iilaser ezinkulu zefiber zikhawuleza ngokwenene. Ukunyuka okubalulekileyo kwimveliso kufuna ukunyuka kwangaxeshanye ekuhambeni kwenitrogen. Iilaser zefiber ezinamandla ziyaba ngumphunga kwaye zinyibilike isinyithi ngaphakathi kwesisikelelo ngokukhawuleza kune-CO2 lasers.
Esikhundleni sokunciphisa umatshini (okuya kuba yinto echaseneyo), silungisa umlomo ukuze ulungele umsebenzi. Oku kwandisa ukuhamba kwegesi encedisayo ngenotshi ngaphandle kokunyusa uxinzelelo. Kuvakala njengomntu ophumeleleyo, ngaphandle kokuba i-laser isahamba ngokukhawuleza kwaye i-tilt iba ngumba ongaphezulu.
Umzobo 1. Iindawo ezintathu eziphambili ezichaphazela iindleko zenxalenye: izixhobo, iindleko zokusebenza (kubandakanywa izinto ezisetyenzisiweyo kunye negesi encedisayo), kunye nomsebenzi. Aba bathathu baya kuba noxanduva lwenxalenye yeendleko zizonke.
Ukuba udweliso lwenkqubo yakho lunobunzima obukhethekileyo bokujikelezisa inxalenye, iyavakala ukukhetha indlela yokusika esebenzisa i-nozzle enkulu yokucima. Ingaba esi sicwangciso sinengqiqo kuxhomekeke kwisicelo. Kufuneka silungelelanise imfuno yozinzo lwenkqubo kunye nokwanda kokusetyenziswa kwegesi encedisayo okuza nokwanda kokufuduswa kwemibhobho.
Enye inketho yokuthintela ukukhutshwa kweengxenye kukutshatyalaliswa kwentloko yemfazwe, eyenziwe ngesandla okanye ngokuzenzekelayo usebenzisa isofthiwe. Kwaye apha kwakhona sijongene nokukhetha. Imisebenzi yokutshatyalaliswa kwentloko yecandelo iphucula ukuthembeka kwenkqubo, kodwa ikwanyusa iindleko ezisetyenziswayo kunye neenkqubo ezicothayo.
Eyona ndlela isengqiqweni yokuthatha isigqibo sokuba kusetyenziswe intshabalalo ye-slug kukuqwalasela ukulahla iinkcukacha. Ukuba oku kuyenzeka kwaye asikwazi ukucwangcisa ngokukhuselekileyo ukunqanda ungquzulwano olunokubakho, sinokhetho oluninzi. Singakwazi ukubopha iindawo ngee-micro-latches okanye sinqumle iziqwenga zetsimbi kwaye sizivumele ziwe ngokukhuselekileyo.
Ukuba iprofayile yengxaki yinkcukacha zonke ngokwayo, ngoko ke asinalo olunye ukhetho, kufuneka siyiphawule. Ukuba ingxaki inxulumene neprofayili yangaphakathi, ngoko kufuneka uqhathanise ixesha kunye neendleko zokulungisa kunye nokuphula ibhloko yensimbi.
Ngoku umbuzo uba yindleko. Ngaba ukongeza ii-microtags kwenza kube nzima ukukhupha inxalenye okanye ibhloko kwindlwane? Ukuba sitshabalalisa intloko yemfazwe, siya kwandisa ixesha lokubaleka kwelaser. Ngaba kutshiphu ukongeza umsebenzi owongezelelweyo kwiindawo ezahlukeneyo, okanye ngaba kutshiphu ukongeza ixesha labasebenzi kumyinge weyure womatshini? Ukunikezelwa kwemveliso ephezulu yomatshini ngeyure, mhlawumbi yehla ekubeni mangaphi amaqhekeza ekufuneka anqunyulwe abe ngamaqhekeza amancinci, akhuselekileyo.
Umsebenzi yindleko enkulu kwaye kubalulekile ukuyilawula xa uzama ukukhuphisana kwimarike yeendleko zabasebenzi. Ukusika iLaser kufuna umsebenzi ohambelana nenkqubo yokuqala (nangona iindleko zincitshisiwe kwii-odolo ezilandelayo) kunye nomsebenzi ohambelana nokusebenza komatshini. Okukhona oomatshini bezenzela, kokukhona sifumana kancinci kumvuzo weyure womsebenzisi welaser.
“I-automation” ekusikeni kwe-laser idla ngokubhekisa ekusetyenzweni nasekuhlelweni kwemathiriyeli, kodwa iilaser zale mihla nazo zineentlobo ezininzi zokuzenzela. Oomatshini banamhlanje baxhotyiswe ngotshintsho lombhobho oluzenzekelayo, ulawulo olusebenzayo lokusikwa komgangatho kunye nolawulo lwezinga lokutya. Lutyalo-mali, kodwa ukongiwa kwabasebenzi okusisiphumo kungathethelela iindleko.
Ukuhlawulwa ngeyure koomatshini belaser kuxhomekeke kwimveliso. Yiba nomfanekiso-ngqondweni womatshini onokwenza kwishifti enye into ebidla ngokuthatha iishifti ezimbini. Kule meko, ukutshintsha ukusuka kwiishifti ezimbini ukuya kwenye kunokuphinda kabini imveliso yeyure yomatshini. Njengoko umatshini ngamnye uvelisa ngakumbi, sinciphisa inani loomatshini abafunekayo ukwenza umsebenzi ofanayo. Ngokunciphisa inani le-lasers ngesiqingatha, siya kuthoba iindleko zomsebenzi ngesiqingatha.
Ngokuqinisekileyo, olu londolozo luya kuhla umbhobho ukuba izixhobo zethu zijika zingathembekanga. Iintlobo ngeentlobo zetekhnoloji zokulungisa zinceda ukugcina ukusika kwe-laser kubaleka kakuhle, kubandakanya ukujonga impilo yomatshini, ujongo oluzenzekelayo lombhobho, kunye nezinzwa zokukhanya ezibona ukungcola kwiglasi ekhuselayo yentloko. Namhlanje, sinokusebenzisa ubukrelekrele bonxibelelwano loomatshini bale mihla ukubonisa ukuba lingakanani ixesha eliseleyo de kufike ukulungiswa okulandelayo.
Zonke ezi mpawu zinceda ukuzenzela eminye imiba yogcino lomatshini. Enoba singabanini oomatshini abanala mandla okanye sigcina izixhobo ngendlela yakudala (ukusebenza nzima kunye nesimo sengqondo esifanelekileyo), kufuneka siqinisekise ukuba imisebenzi yokulondoloza igqityezelwa ngokufanelekileyo nangexesha.
Umzobo 2. Ukuqhubela phambili kwi-laser cutting kusagxilwe kumfanekiso omkhulu, kungekhona nje ukusika isantya. Ngokomzekelo, le ndlela ye-nanobonding (ukudibanisa ii-workpieces ezimbini ezisikwe ngomgca oqhelekileyo) iququzelela ukuhlukana kwamacandelo amaninzi.
Isizathu silula: oomatshini kufuneka babe kwimeko yokusebenza ephezulu ukuze bagcine ukusebenza kakuhle kwezixhobo zokusebenza (OEE): ukufumaneka x imveliso x umgangatho. Okanye, njengoko iwebhusayithi ye-oee.com ibeka: “[OEE] ichaza ipesenti yexesha elisebenza ngokwenene lokuvelisa. I-OEE ye-100% ithetha umgangatho we-100% (amacandelo asemgangathweni kuphela), ukusebenza kwe-100% (ukusebenza ngokukhawuleza). ) kunye nokufumaneka kwe-100% (akukho xesha lokuphumla)." Ukufezekisa i-100% ye-OEE akunakwenzeka kwiimeko ezininzi. Umgangatho woshishino usondela kwi-60% nangona i-OEE eqhelekileyo iyahluka ngokusetyenziswa, inani loomatshini kunye nobunzima bokusebenza. Nokuba yeyiphi na indlela, ukugqwesa kwe-OEE yeyona nto ifanelekileyo ukulwela.
Khawucinge ukuba sifumana isicelo sekowuti yeengxenye ezingama-25,000 kumxhasi omkhulu nowaziwayo. Ukuqinisekisa ukusebenza kakuhle kwalo msebenzi kunokuba nefuthe elibonakalayo ekukhuleni kwenkampani yethu kwixesha elizayo. Ke sinikezela nge-100,000 yeedola kwaye umxhasi uyamkela. Ezi ziindaba ezimnandi. Iindaba ezimbi kukuba imida yethu yenzuzo mincinci. Ke ngoko, kufuneka siqinisekise elona nqanaba liphezulu le-OEE. Ukuze senze imali, kufuneka senze konke okusemandleni ethu ukwandisa indawo eluhlaza kunye nokunciphisa indawo e-orenji kuMfanekiso 3.
Xa imida isezantsi, naziphi na izinto ezothusayo zinokujongela phantsi okanye zide zibhangise iingeniso. Ngaba inkqubo embi iwonakalisa umlomo wam? Ngaba igeyiji yokusikwa kakubi iya kungcolisa iglasi yam yokhuseleko? Ndinexesha lokuphumla elingacwangciswanga kwaye kuye kwafuneka ndiphazamise imveliso yolondolozo lothintelo. Oku kuya kuyichaphazela njani imveliso?
Udweliso lwenkqubo olulambathayo okanye ulondolozo lunokubangela ukuba i-feedrate elindelekileyo (kunye ne-feedrate esetyenziselwa ukubala ixesha elipheleleyo lokusetyenzwa) ibe ngaphantsi. Oku kunciphisa i-OEE kwaye kwandisa ixesha lokuvelisa ngokubanzi - nangaphandle kwesidingo sokuphazamisa imveliso ukulungisa iiparamitha zoomatshini. Xela ukufumaneka kwemoto.
Kwakhona, ngaba amalungu esiwenza ngokwenene athunyelwa kubathengi, okanye ezinye iindawo zilahlwe kumgqomo wenkunkuma? Amanqaku akumgangatho ophantsi kwizibalo ze-OEE anokwenzakalisa ngokwenene.
Iindleko zokusika iLaser zijongwa ngokweenkcukacha ngakumbi kunokuhlawula nje ixesha elithe ngqo lelaser. Izixhobo zoomatshini zanamhlanje zibonelela ngeendlela ezininzi zokunceda abavelisi ukuba bafezekise inqanaba eliphezulu lokungafihli nto abayidingayo ukuze bahlale bekhuphisana. Ukuze sihlale sinenzuzo, sifuna nje ukwazi nokuqonda zonke iindleko ezifihliweyo esizihlawulayo xa sithengisa amawijethi.
Umfanekiso wesi-3 Ngokukodwa xa sisebenzisa imida emincinci kakhulu, kufuneka sinciphise i-orenji kwaye sandise iblue.
