Kwimizi-mveliso yangoku, ngakumbi{0}}kumacandelo achanekileyo afana neemoto, ezombane, kunye ne-aerospace, ukhetho lwezixhobo zokuwelda lumisela ngokuthe ngqo umgangatho wemveliso kunye nokusebenza kakuhle kwemveliso. II-Capacitor Discharge Welder(CDW) kunye neSpot Welderzitekhnoloji ezimbini eziphambili kwi-resistance welding. Ngelixa omabini enokufikelela{1}umgangatho ophezulu wokujoyina intsimbi, i-CDW ibonisa ukhuphiswano olungundoqo olungenakuphinda lubuyiselwe kwizicelo ezibalulekileyo ezifuna ukuchaneka okuphezulu, igalelo lobushushu obuphantsi, kunye nokuwelda kwemathiriyeli eyodwa, enkosi kumgaqo wayo owodwa wokusebenza.
Eli nqaku liza kusebenzisa idatha yobuchwephesha kunye{0}}yeemeko zesicelo zehlabathi zokwenyani ukuhlalutya iingenelo ezine ezingundoqo ze-CDW ngaphezulu kwe-MFDC, ibonelela ngeengcebiso ezisebenzayo zokukhetha ukunceda amashishini enze ezona zigqibo zinolwazi ngexesha lokuthengwa kwezixhobo kunye nophuculo lobuchwepheshe.
Ukunyamezelwa kweGridi yaMandla aPhakamileyo kunye neMpembelelo yaMandla amancinci
Olona ncedo lubalulekileyo lwe-CDW yigridi -yobuhlobo kunye nefuthe eliphantsi lamandla. Oku kubalulekile kwimo engqongileyo yokuvelisa enegridi zamandla ezingazinzanga okanye iimfuno eziphezulu zomgangatho wamandla.
Umjikelo-uGcino{1}}Umjikelo wokukhupha uchaziwe
I-CDW isebenza kumjikelo wezigaba ezintathu-: "Tshaja{1}Gcina{2}}Ukukhupha." Iqala isebenzisa i-transformer encinci yamandla ukuhlawula ibhanki enkulu ye-capacitors ixesha elide (umzekelo, imizuzwana emininzi), ukugcina amandla ombane. Emva kokuba i-voltage ye-capacitor ifikelele ekujoliswe kuyo, inkqubo yokulawula ngokukhawuleza ibangela ukukhutshwa. Amandla agciniweyo aye akhululwe{8}ngesiguquli esinamandla sokumelana ne-welding kwindawo yokusebenza ngexesha elifutshane kakhulu, ukugqiba ukuwelda.
Ngokuchaseneyo, iSpot welder ifuna okuqhubekayo, {0}amandla aphezulu-ungeniso lwesigaba sesithathu. Ukusebenza kwayo ngoku kutsalwa ngokuthe ngqo kwigridi yamandla kwaye iguqulelwa phakathi-i-frequency DC nge-inverter ye welding.
Kutheni kubalulekile kwiZibonelelo eziDala okanye iiNdawo ezineGrid Fluctuation
Imowudi yokusebenza yeCDW ibangela impembelelo encinci kwigridi yamandla. Ngexesha lokutshaja, ifuna kuphela amandla asezantsi egalelo (umzekelo, i-20kJ umthamo we-CDW unokufuna kuphela iikilowathi ezimbalwa zamandla okutshaja) kwaye izoba i-balanced{2}}yesigaba sesithathu somthwalo. Nangona amandla okukhutshwa ngoko nangoko ngexesha lokukhutshwa anokufikelela kumakhulu eekilowatts, ixesha elifutshane kakhulu lithetha ukuba impembelelo yexeshana kwigridi ayinanto.
Kwiinkampani ezinomthamo olinganiselweyo wegridi, amaziko amadala, okanye imeko yobonelelo lwamandla eguquguqukayo, ukukhetha i-CDW kunokuthintela ngokufanelekileyo imiba efana nediphu yombane, izibane ezikhanyayo, okanye nokuvalwa kwezinye izixhobo ezichanekileyo ezibangelwa kukuqaliswa komatshini wokuwelda. Oku kunciphisa kakhulu imingcipheko yemveliso kunye neendleko ezincedisayo ezinxulumene nemiba yobulunga bamandla.
Indawo eChaphazeleke bubushushu obuncinci (HAZ) ukusuka kwiMilisecond Discharge
Kwi-welding echanekileyo, ukulawula umphumo we-thermal kwi-workpiece ngumqondiso obalulekileyo wokusebenza. I-CDW inenzuzo egqibeleleyo kulo mba.
Umahluko osemgangathweni phakathi kwe-0.003 kunye ne-0.1s: Ukuthintela ukuguquka kombala kunye nokuguqulwa
Ixesha lokukhutshwa kwe-CDW ngokuqhelekileyo liqala kwi-0.003 imizuzwana ukuya kwi-0.01 isekhondi, ubude bezinga le-ultra-elifutshane, i-millisecond{3}}. Xa kuthelekiswa, ixesha le-welding ye-welder ye-MFDC idla ngokuba yi-0.1 imizuzwana okanye ngaphezulu.
Eli xesha lifutshane kakhulu lokukhupha lithetha ukuba ubushushu be-welding bugxile kakhulu kwindawo ye-weld, kuthintela ubushushu ukuba busasazeke kwizinto ezijikelezileyo. Oku kubangela ukuba:
- Ukunciphisa i-Workpiece Deformation: Ibaluleke kakhulu kumaphepha abhityileyo okanye izinto ezifuna ukucaba okuphezulu kakhulu.
- Ukunqanda i-Oxidation ye-Surface kunye ne-Discoloration: Oku kunciphisa okanye kuphelisa imfuno yamanyathelo okucutshungulwa okwesibini njengokusila okanye ukupolisha.
UKhetho oluKhethekileyo lwe-Electronics oluchanekileyo kunye nezixhobo zokuthambisa
I-CDW lukhetho olwamkelweyo lwezicelo ezinje ngezixhobo ze-elektroniki, izixhobo ezichanekileyo, iibhendi zobucwebe bezacholo, kunye neendawo zangaphakathi zeemoto apho imbonakalo iphambili. Umzekelo, xa udibanisa izinto ze-elektroniki ezinobuthathaka, i-HAZ encinci ikhusela ngokufanelekileyo iisekethe ezijikelezileyo kunye nezinto kumonakalo wobushushu.
Ultra-Uzinzo lwaMandla aPhezulu kunye nokuZinzo eMgangathweni
Ukukhutshwa kwamandla okuzinzileyo sisiseko somgangatho we-weld ongaguqukiyo kwimveliso yebhetshi. I-CDW ifezekisa uzinzo lwamandla aphezulu ngendlela eyodwa.
Ulawulo lweVoltage ye-PLC echanekileyo (Impazamo < 1%)
Ngaphambi kokukhutshwa, i-CDW kufuneka ilinde de i-voltage ye-capacitor ifikelele kwixabiso elichanekileyo elijoliswe kuyo elisekwe yi-PLC (i-Programmable Logic Controller). Inkqubo ibangela kuphela ukukhutshwa xa impazamo yombane ingaphantsi kwe-1%. Le "Gcina Kuqala, Ukukhupha okwesibini" inkqubo iqinisekisa ngokusisiseko ukuba igalelo lamandla kuyo yonke i-weld iyahambelana kakhulu, ngokuqinisekileyo ikhuselekile kuguquko lwegridi yamandla.
Ngelixa iSpot welder iphumeza ulawulo oluchanekileyo lwangoku ngobuchwepheshe be-inverter, imveliso yayo yamandla isaxhomekeke kwigalelo lokwenyani-kwigridi yexesha. Ngexesha elide-,{3}}imveliso yevolumu ephezulu, ukuguquguquka okungephi kwegridi kusengakhokelela kwiimpazamo ezongezelekayo kumandla wokuwelda.
Ukusukela "Zero Defects" kwiBatch Production
Kwimveliso ephezulu-yevolumu yeendawo zemoto, iithebhu zebhetri, kunye nezinye izinto ezifuna ukungaguquguquki okuphezulu kunye neziphene zero, i-CDW iqinisekisa ukuba indawo nganye ye-weld inobukhulu obufanayo be-nugget kunye namandla. Oku kunciphisa kakhulu ukusebenza kwakhona kunye namazinga okulahlwa, kunika isiqinisekiso esiluqilima kumashishini ajolise{2}umgangatho ophezulu,{3}}ophezulu wemveliso esebenzayo.
Ingcaphephe yeMulti-iProjekthi kunye neMetal yeWelding engafaniyo
I-CDW ibonisa ukuguquguquka kwenkqubo enamandla xa ijongene nemathiriyeli eyodwa kunye neenkqubo ze-welding ezinzima.
Ukusebenza kwiSitampu esishushu kunye neziPhezulu{0}}zeZintsimbi zamandla
Ngokubhekiselele kwizithuthi ezikhaphukhaphu, ukusetyenziswa kwentsimbi eshushu enesitampu (efana ne-22MnB5+i-AlSi) kunye nentsimbi ephezulu{2}}yayanda. Ezi zixhobo zinamandla aphezulu kunye nokungahambi kakuhle kwe-thermal, kufuna umbane ophezulu kakhulu ngokukhawuleza ukwenza i-weld nugget efanelekileyo. I-CDW inokukhulula umsinga ophakamileyo wamakhulu amawaka e-amperes kwi-milliseconds, ingena lula kwiingubo zomphezulu zokwenza ii-weld nuggets ezikumgangatho ophezulu.
Idata egunyazisiweyo ibonisa ukuba ekutsaleni{0} ngaphandle kovavanyo lwamandla kwiziqinisekiso zokuwelda (umzekelo, i-M14 nuts) kwiindawo zemoto ezinesitampu ezishushu, iCDW{4}}iziqhoboshi ezidityanisiweyo zifumene ixabiso lovavanyo oluyi-avareji ye-26.0 kN, egqithise ngokubonakalayo ubuncinci bemfuno yomenzi ye-5.1 kN. Oku kuqinisekisa ngokuqinileyo ukuthembeka kwayo kwi-welding yezinto eziphathekayo.
UkuWelding okuPhezulu{0}}kwezinyithi zokuSebenza ezinje ngeKopolo kunye neAluminiyam
I-CDW ifaneleke ngokukodwa-ukuwelda iintsimbi ezisebenza kakuhle neziqhubayo{1}}ezingeyoron, ezifana nobhedu, ialuminiyam, i-nickel, kunye nealloys zazo. Ngenxa yokutshatyalaliswa kobushushu ngokukhawuleza, iiwelder eziqhelekileyo ziyasokola ukwenza i-weld nugget ngaphambi kokuba ubushushu bunwenwele. I-CDW isebenzisa ubuninzi bayo-ixesha elifutshane, ultra-impawu eziphezulu zangoku ukugqiba i-weld phambi kokuba ubushushu buphele, ukusombulula ngempumelelo umceli mngeni wokuwelda okuphezulu{6}}kwesinyithi sokusebenza.
Ku-Uthelekiso olunzulu: CDW vs. Spot Welders
Ukubonelela ngesikhokelo esicacileyo sokukhetha, itheyibhile engezantsi ishwankathela umahluko phakathi kweentlobo ezimbini zezixhobo kwiiparitha eziphambili zobugcisa kunye neemeko zesicelo:
