Ukusika iplasma yerobhothi edibeneyo ifuna okungaphezulu nje kwetotshi encanyathiselwe ekupheleni kwengalo yerobhothi.Ulwazi lwenkqubo yokusika iplasma lungundoqo.ubuncwane
Abaqulunqi besinyithi kulo lonke ishishini - kwiiworkshops, oomatshini abanzima, ukwakha iinqanawa kunye nentsimbi yesakhiwo - bazama ukuhlangabezana nokulindela ukuhanjiswa okufunwayo ngelixa bedlula iimfuno ezisemgangathweni. Bahlala befuna ukunciphisa iindleko ngelixa bejongene nengxaki ehlala ikhona yokugcina abasebenzi abanezakhono. akukho lula.
Uninzi lwezi ngxaki zinokulandwa emva kwiinkqubo zezandla ezisaxhaphakileyo kweli shishini, ingakumbi xa kusenziwa iimveliso ezinobumba obuntsonkothileyo ezinjengezivalo zesikhongozelo semizi-mveliso, izakhi zentsimbi ezigobileyo, nemibhobho netyhubhu. ixesha lomatshini lokumakisha ngesandla, ukulawula umgangatho, kunye nokuguqulwa, xa ixesha lokusika langempela (ngokuqhelekileyo nge-oxyfuel ebanjwe ngesandla okanye i-plasma cutter) kuphela i-10 ukuya kuma-20 ekhulwini.
Ukongeza kwixesha elichithwe yinkqubo yezandla, uninzi lwezi zithintelo zenziwa malunga neendawo ezingalunganga, imilinganiselo okanye unyamezelo, efuna imisebenzi ebanzi efana nokusila kunye nokusebenza kwakhona, okanye okubi ngakumbi, izinto ezifuna ukuchithwa. kakhulu njenge-40% yexesha labo lokucubungula lilonke kulo msebenzi wexabiso eliphantsi kunye nenkcitho.
Konke oku kukhokelele kushishino olutyhalela phambili kwi-automation.Ivenkile eyenza imisebenzi yokusika itotshi yezandla kwiindawo ezintsonkothileyo ze-axis ezininzi ziphunyezwe iseli yokusika iplasma yerobhothi kwaye, ngokungamangalisiyo, yabona inzuzo enkulu.Lo msebenzi uphelisa ukucwangciswa kwezandla, kunye nomsebenzi othi kuya kuthatha 5 abantu 6 iiyure ngoku kungenziwa kwimizuzu nje 18 usebenzisa irobhothi.
Nangona iinzuzo zicacile, ukuphumeza ukusika i-robotic plasma kufuna okungaphezulu nje kokuthenga i-robot kunye netotshi ye-plasma.Ukuba ucinga ukusika i-robotic plasma, qiniseka ukuba uthathe indlela epheleleyo kwaye ujonge umlambo wexabiso lonke.Ukongezelela, sebenzisa umdibanisi wenkqubo oqeqeshelwe umenzi oqondayo kwaye uyayiqonda iteknoloji yeplasma kunye namalungu enkqubo kunye neenkqubo ezifunekayo ukuqinisekisa ukuba zonke iimfuno zidibaniswe kuyilo lwebhetri.
Kwakhona qwalasela i-software, leyo ngokungathandabuzekiyo yenye yezona nxalenye zibaluleke kakhulu kuyo nayiphi na i-robotic plasma cutting system.If utyale imali kwinkqubo kwaye isoftware inokuba nzima ukuyisebenzisa, ifuna ubuchule obuninzi bokuqhuba, okanye uyifumene. kuthatha ixesha elininzi ukulungelelanisa i-robot kwi-plasma yokusika kwaye ufundise indlela yokusika, uchitha nje imali eninzi.
Nangona i-software yokulinganisa i-robotic ixhaphakile, iiseli zokusika i-robotic plasma ezisebenzayo zisebenzisa i-software yeprogram ye-robotic engaxhunyiwe kwi-intanethi eya kwenza ngokuzenzekelayo inkqubo ye-robot yendlela, ukuchonga kunye nokuhlawulela ukungqubana, kunye nokudibanisa inkqubo yokusika i-plasma yolwazi.Ukubandakanya ulwazi lwenkqubo ye-plasma enzulu ngundoqo.Nge-software efana nale. , Ukuziqhelanisa nezona zicelo zinzima kakhulu zokusika iplasma kuba lula kakhulu.
I-Plasma cut complex multi-axis shapes ifuna ijiyometri yetotshi eyodwa.Faka ijiyometri yetotshi esetyenziswa kwi-XY application eqhelekileyo (jonga uMfanekiso 1) kwimilo entsonkothileyo, efana nentloko yenqanawa yoxinzelelo olugobileyo, kwaye uya kwandisa ukubakho kokungqubana. Ngenxa yesi sizathu, iitotshi ezibukhali ezibukhali (ezinoyilo "oluchongileyo") zifaneleke ngakumbi ukusika imilo yerobhothi.
Zonke iintlobo zontlitheko azinakuthintelwa ngetotshi ene-angle ebukhali yodwa. Inkqubo yecandelo kufuneka iqulathe utshintsho kumphakamo osikiweyo (okt incam yetotshi kufuneka icace kwisixhobo sokusebenza) ukunqanda ukungqubana (jonga uMfanekiso 2).
Ngexesha lenkqubo yokusika, igesi yeplasma iqukuqela isezantsi kumzimba wetotshi kwicala le-vortex ukuya kwincam yetotshi. Esi senzo sokujikeleza sivumela amandla e-centrifugal ukuba atsale amasuntswana anzima aphume kuluhlu lwerhasi ukuya kumda womngxuma womlomo kwaye ikhusela indibano yetotshi ukusuka. ukuhamba kwee-electron ezishushu.Ubushushu beplasma busondele kwi-20,000 degrees Celsius, ngelixa iinxalenye zobhedu zetotshi zinyibilika kwi-1,100 degrees Celsius.Izinto ezisetyenziswayo zifuna ukukhuselwa, kunye ne-insulating layer of particles enzima inika ukhuseleko.
Umzobo 1. Imizimba yetotshi esemgangathweni yenzelwe ukusika i-sheet metal.Ukusebenzisa itotshi efanayo kwisicelo se-multi-axis kwandisa ithuba lokungqubana kunye ne-workpiece.
I-Swirl yenza elinye icala le-arc elisikiwe libe shushu kunelinye. Iitotshi ezinerhasi ejikelezayo ngaxeshanye zibeka icala elishushu lokusikwa kwicala lasekunene le-arc (xa ijongwe ngaphezulu kwicala le-arc). injineli yenkqubo isebenza nzima ukukhulisa icala elilungileyo lokusikwa kwaye ithatha ukuba icala elibi (ekhohlo) liya kuba sisilaphu (bona uMfanekiso 3).
Iimpawu zangaphakathi kufuneka zinqunywe ngendlela echasene ne-clockwise, kunye necala elitshisayo le-plasma lenza i-cut cut ecocekileyo kwicala lasekunene (inxalenye yomgca wecala) Itotshi inqumla kwicala elingalunganga, inokudala i-taper enkulu kwiprofayili esikiweyo kwaye inyuse inkunkuma kumda wenxalenye.
Qaphela ukuba uninzi lweetafile zokusika iipaneli zeplasma zinenkqubo yobukrelekrele eyakhelwe kwisilawuli malunga nesalathiso se-arc cut. ngoko ke kubalulekile ukuba nesoftware yenkqubo yerobhothi engaxhunyiwe kwi-intanethi ngolwazi lwenkqubo yeplasma edibeneyo.
Intshukumo yetotshi esetyenziselwa ukugqobhoza isinyithi inefuthe elithe ngqo kwi-plasma yokusika izinto ezisetyenziswayo.Ukuba itotshi yeplasma igqobhoza iphepha kwindawo yokusika (ikufuphi kakhulu nesixhobo sokusebenzela), ukurhoxa kwentsimbi etyhidiweyo kunokonakalisa ikhaka kunye nombhobho ngokukhawuleza. umgangatho ophantsi wokusika kunye nokunciphisa ubomi obusebenzisekayo.
Kwakhona, oku kunqabile ukwenzeka kwi-sheet metal ukusika izicelo kunye ne-gantry, njengoko iqondo eliphezulu lobuchwephesha betotshi sele lakhelwe kwisilawuli. .
Okokuqala, itotshi yenza inkqubo yokubona ukuphakama, ngokuqhelekileyo isebenzisa isignali ye-ohmic ukuze ibone indawo yokusebenza. Xa i-arc yeplasma idlulisiwe, inokufudumeza ngokupheleleyo.Kweli nqanaba itotshi ihambela kumphakamo wokugqobhoza, okungumgama okhuselekileyo ukusuka kwisixhobo sokusetyenzwa nangaphezulu ukusuka kwi-blowback yezinto ezityhidiweyo.Itotshi iyayigcina le nto. umgama de i-arc ye-plasma ingene ngokupheleleyo kwi-plate.Emva kokulibaziseka kokubhoboza kugqityiwe, itotshi ihla isiya kwi-plate yentsimbi kwaye iqalise intshukumo yokusika (jonga uMzobo 4).
Kwakhona, bonke obu bulumko buhlala bukhelwe kwisilawuli seplasma esisetyenziselwa ukusika iphepha, kungekhona umlawuli we-robot. Isenokungabi kwelona cala lilungileyo lesixhobo sokusebenza kunye nobukhulu bezinto eziphathekayo.Ukuba itotshi ayihambelani nomphezulu wesinyithi ewugqobhozayo, iya kuphelela ekusikeni umnqamlezo otyebileyo kunokuba kuyimfuneko, ichitha ubomi obusebenzisekayo. kwicala elingalunganga inokubeka indibano yetotshi kufutshane kakhulu kumphezulu womsebenzi, iveze ukuba iyanyibilika iblowback kwaye ibangele ukusilela kwangaphambi kwexesha (jonga uMfanekiso 5).
Qwalasela inkqubo yokusika iplasma yerobhothi ebandakanya ukugoba intloko yomkhumbi woxinzelelo. Ngokufana nokusikwa kweshiti, itotshi yerobhothi kufuneka ibekwe ngokuthe ngqo kumphezulu wezinto ezibonakalayo ukuze kuqinisekiswe eyona nxalenye incinci inqamlezayo enokwenzeka yokugqobhoza. Njengoko itotshi yeplasma isondela kwindawo yokusebenza. , isebenzisa inzwa yobude de ifumane umphezulu wenqanawa, emva koko irhoxe ecaleni kwe-axis yetotshi ukuhambisa umphakamo.Emva kokuba i-arc ikhutshiwe, itotshi irhoxiswa kwakhona ecaleni kwe-axis yetotshi ukugqobhoza umphakamo, ngokukhuselekileyo kude ne-blowback (bona uMfanekiso 6) .
Emva kokuba ukulibaziseka kwe-pierce kuphelile, i-torch iyancipha ukuya kubude bokusika.Xa ukucubungula i-contours, i-torch ijikeleziswa ukuya kwindlela yokusika efunwayo ngaxeshanye okanye ngamanyathelo.Ngeli nqanaba, ukulandelelana kokusika kuqala.
Iirobhothi zibizwa ngokuba zii- overdetermined systems.Loo nto ithe, ineendlela ezininzi zokufika kwindawo enye.Oku kuthetha ukuba nabani na ofundisa irobhothi ukuhamba, okanye nabani na ongomnye, kufuneka abe nenqanaba elithile lobuchwephesha, nokuba kukuqonda intshukumo yerobhothi okanye ukwenza machining. iimfuno zokusika iplasma.
Nangona iipendenti zokufundisa ziye zavela, eminye imisebenzi ayifanelanga ngokwemvelo ukufundisa ipendant programming-ingakumbi imisebenzi ebandakanya inani elikhulu lamalungu axubeneyo anomthamo ophantsi. iintsuku zamalungu antsonkothileyo.
I-software yeprogram ye-robot engaxhunyiwe kwi-intanethi eyenzelwe iimodyuli zokusika i-plasma iya kubethelela obu buchule (jonga uMzobo 7) .Oku kubandakanya ulwalathiso lokusika igesi ye-plasma, ukuqonda ukuphakama kokuqala, ukulandelelana kokubhoboza, kunye nokulungiswa kwesantya sokusika kwitotshi kunye neenkqubo zeplasma.
Umzobo 2. Iitotshi ezibukhali ("ezikhonjiweyo") zifaneleka ngakumbi kwi-robotic plasma cutting.Kodwa nangona ezi geometri zetotshi, kungcono ukunyusa ukuphakama okusikiwe ukunciphisa ithuba lokungqubana.
Isoftware ibonelela ngobuchwephesha berobhothi obufunekayo kwiprogram ye-systems.Ilawula ubunye, okanye iimeko apho i-robotic end-effector (kule meko, itotshi yeplasma) ayikwazi ukufikelela kwi-workpiece;imida edibeneyo;ukuhamba ngokugqithisileyoukuqengqeleka kwesihlahla;ukufumanisa ukungqubana;iizembe zangaphandle;kunye ne-toolpath optimization.Okokuqala, umdwelisi weprogram ungenisa ifayile ye-CAD yenxalenye egqityiweyo kwi-software yeprogram ye-robot engaxhunyiwe kwi-intanethi, emva koko ichaza umda oza kunqunyulwa, kunye nendawo yokubhoboza kunye nezinye iiparameters, kuthathelwa ingqalelo ukungqubana kunye nemiqobo yoluhlu.
Ezinye zokuphindaphinda zamva nje zesoftware yerobhothi engasebenziyo zisebenzisa into ebizwa ngokuba yinkqubo esekwe kwi-intanethi yomsebenzi.Le ndlela ivumela abadwelisi benkqubo ukuba bavelise ngokuzenzekelayo iindlela zokusika kwaye bakhethe iiprofayili ezininzi ngexesha elinye.Umdwelisi wenkqubo unokukhetha umkhethi wendlela ephetheyo ebonisa indlela yokusika kunye nesikhokelo. , kwaye emva koko ukhethe ukutshintsha indawo yokuqala kunye nesiphelo, kunye nesalathiso kunye nokuthambekela kwetotshi yeplasma.Ucwangciso luqala ngokubanzi (oluzimeleyo uphawu lwengalo yerobhothi okanye inkqubo yeplasma) kwaye iqhubela phambili ukubandakanya imodeli ethile yerobhothi.
Ukulinganisa okubangelwayo kunokuthathela ingqalelo yonke into ekwiseli yerobhothi, kubandakanywa izinto ezifana nezithintelo zokhuseleko, izixhobo, kunye neetotshi zeplasma.Ithi ke iphendule naziphi na iimpazamo ezinokwenzeka zekinematic kunye nokungqubana kumqhubi, onokuthi emva koko alungise ingxaki.Ngokomzekelo, ukulinganisa kunokubonakalisa ingxaki yongquzulwano phakathi kokusikeka okubini okuhlukeneyo kwentloko yomkhumbi woxinzelelo.Isithintelo ngasinye sinobude obuhlukeneyo ecaleni kwe-contour yentloko, ngoko ke ukunyakaza okukhawulezayo phakathi kokusikeka kufuneka kuphendule ukukhutshwa okuyimfuneko-inkcukacha encinci, isonjululwe ngaphambi kokuba umsebenzi ufikelele emgangathweni, onceda ukuphelisa iintloko kunye nenkcitho.
Ukunqongophala okuqhubekayo kwabasebenzi kunye nokukhula kweemfuno zabathengi kuye kwabangela ukuba abavelisi abaninzi baphendukele kwi-robotic plasma cutting.Ngelishwa, abantu abaninzi bangena emanzini ukuze bafumane iingxaki ezingakumbi, ngakumbi xa abantu abadibanisa i-automation bengenalo ulwazi lwenkqubo yokusika i-plasma.Le ndlela iya kuphela. kukhokelela ekudandathekeni.
Hlanganisa ulwazi lokusika iplasma kwasekuqaleni, kwaye izinto ziyatshintsha.Ngobukrelekrele benkqubo yeplasma, irobhothi inokujikeleza kwaye ishukume njengoko kufunekayo ukwenza eyona nto isebenzayo ukugqobhoza, ukwandisa ubomi bezinto ezisetyenziswayo.Isika ngendlela echanekileyo kwaye iqhube ukuphepha nayiphi na into yokusebenza. ukungqubana.Xa ulandela le ndlela yokuzenzela, abavelisi bavuna umvuzo.
