Kwimveliso yeemoto zanamhlanje, umgangatho we-weld uchaphazela ngqo ukhuseleko lwesakhiwo semoto, ixesha lomjikelo wemveliso, kunye nokusebenza kakuhle kweendleko. Iqhutywa yindlela yokukhanya, ukusetyenziswa kwentsimbi ephezulu{1}}ephezulu kunye nealloyi zealuminiyam kunyuke kakhulu. I-AC yesiqheloamabala abawelder, kunye nokuguquguquka okukhulu kwangoku kunye nobunzima bokulawula ngokuchanekileyo igalelo lokushisa, bahlala bezabalaza ngezi zinto zitsha, ezikhokelela kwi-spatter egqithisileyo, ukubunjwa kwe-nugget okungahambelaniyo, kunye namazinga aphezulu e-defect.
Njengomboneleli okhokelayo wezisombululo zokuwelda, iHaifei Welding Equipment Co., Ltd., ngomsebenzi wayo kunye neeOEM ezininzi kunye neTier 1 ababoneleli, ibonise ukuba iMedium Frequency Direct Current (MFDC) Spot Welders -kunye nokuguqulwa kwamaxesha angaphezulu kwe-1000Hz kunye ne-millisecond yolawulo{5}lomgangatho wokwenza i-millisecond{5} iinxalenye zeemoto. Eli nqaku libonelela nge{8}}uhlalutyo olunzulu lweenkqubo ezine ezingundoqo zesicelo se-MFDC abashiseli bendawo kwimveliso yeemoto, kunye neengcebiso ezisebenzayo zokukhetha.
Umzimba-ku{1}}Mhlophe (BIW) Welding: Isisombululo seAHSS kunye neGalvanized Steel
Umzimba{0}ku{1}Mhlophe wenza amathambo esithuthi. Umlinganiselo ophakathi-ubukhulu be-sedan BIW iqulathe phakathi kwe-4,000 kunye ne-6,000 yeendawo ze-weld, malunga ne-20% ehlelwe njengebalulekileyo kukhuseleko lwengozi.
1. Ukunciphisa uMngcipheko we-Brittle Fracture kwi-AHSS
Amaqumrhu eemoto anamhlanje asebenzisa kakhulu ucinezelo-intsimbi eqinisiweyo (PHS) enamandla angaphaya kwe-1500 MPa. Ezi zixhobo zivakalelwa kakhulu kwigalelo lobushushu; ukupholisa ngokukhawuleza okugqithisileyo kunokukhokelela kwi-weld nugget embrittlement. Abashiseli beMFDC basebenzisa -iteknoloji yolawulo lwepulse yangoku ukwazisa "i-tempering current" emva kweyona weld ingundoqo. Oku kucothisa ngempumelelo izinga lokupholisa kwaye kwandisa i-nugget ductility. Idatha yasendle ibonisa ukuba ukomelela kwe-chear tensile ye-AHSS welds kunokuphuculwa rhoqo ngaphezulu kwe-15% xa kusetyenziswa ubuchwepheshe be-MFDC.
2. Ukuphelisa imiba yeSpatter kwiNtsimbi yeGalvanized
Xa welding steel galvanized, i-zinc coating iyanyibilika phambi kwezinto ezisisiseko, ngokufuthi ibangela ukutshiza okukhulu kunye nokungcoliswa kwe-electrode. Iiwelder ze-MFDC zinexesha le-1ms langoku lokuphendula, livumela "ishedyuli enzima" ukuwelda{2}}ukuhambisa umsinga ophezulu ngexesha elifutshane kakhulu lokugqobhoza umaleko we-zinc ngaphandle kokutshisa kwizinto ezisisiseko. Olu lawulo luchanekileyo lonyusa izinga lokuqala lokwamkelwa kwe-weld ukuya kuthi ga kwi-99.5%, kunciphisa ngokubonakalayo ukucola nokusetyenzwa kwakhona.
Iitreyi zeBattery ze-EV: "I-Oxide Film Buster" ye-Aluminiyam yokuWelding
Iitreyi zebhetri yemoto yombane zihlala zisebenzisa i-6xxx ye-aluminium alloys, apho ifilimu eshinyeneyo ye-oxide (Al₂O₃) ibonisa owona mceli mngeni mkhulu wokuwelda.
1. Ukungeniswa kweFilimu ye-Oxide echanekileyo
Ukuwelda indawo yeAluminiyam kufuna ulawulo lwangoku oluphezulu kakhulu kunye noxinzelelo oluchanekileyo. Iiwelder zeMFDC zaseHaifei zisebenzisa indibaniselwano yoxinzelelo olunyathelweyo kunye-nobushushu bangoku ukuthambisa ifilimu yeoxide phambi kweweld enkulu. Kuyacetyiswa ukuseta kwangaphambili-ixesha lokucudisa i-aluminiyam yokuwelda phakathi kwemizuzwana eyi-0.3 kunye ne-0.6 ukuqinisekisa ukuba i-electrode icinezele ngokupheleleyo imathiriyeli phambi kokukhutshwa okungundoqo kwangoku, ukuzuza isitshizi{6}}mahhala, uqhagamshelwano oluthembekileyo.
2. Isiqinisekiso esiBabini sokutywinwa kweHermetic kunye neMfezeko yoLwakhiwo
Iipakethi zebhetri zifuna ukutywinwa okungqongqo kwe-hermetic. Uphawu lwemveliso ye-DC ye-welders ye-MFDC iqinisekisa inkqubo ye-welding ezinzileyo kunye nokwakhiwa kwe-nugget efanayo. Ityala lesicelo elisuka kumboneleli omkhulu webhetri libonise ukuba ukutshintshela kwisisombululo seMFDC kunciphise izinga lokukhubazeka kwetreyi ukusuka kwi-1.2% ukuya kwi-0.03% nje kuphela, nge-100% yokuphumelela uxinzelelo lwe-OEM{5}olusekelwe kuvavanyo lokuvuza.
Amacandelo e-Chassis kunye noKhuseleko: Usukelo lwe "Zero Defects" phantsi koMthwalo ophezulu
Izakhelo ezisezantsi, izibiyeli zebhanti lesihlalo, kunye nezinto ezixhonyiweyo zithwala imithwalo eguqukayo yesithuthi, efuna kufutshane{0}}ukomelela kweweld agqibeleleyo.
1. Ukugcina amandla ezinto ezisisiseko
Izinto zeChassis ziqhelekile ukuba ngqindilili, kwaye ukuwelda ngokwesintu kuhlala kukhokelela kubushushu obumandla{0}}INdawo eChaphazelekayo (HAZ) ukuthamba. Abashiseli be-MFDC basebenzisa amandla abo aphezulu ekunciphiseni i-HAZ ngelixa beqinisekisa i-nugget ye-diameter efunekayo (ngokuqhelekileyo $\\ge 5\\sqrt{t}$, apho i-$ t $ i-sheet thickening), ngaloo ndlela igcina iimpawu zokuqala ze-mechanical zecandelo.
2. Ukuziqhelanisa neMveliso yeRobhothi ePhezulu{1}}yeMjikelo
Kwimigca ezenzekelayo, ixesha lokujikeleza kwe-welding lihlala linyanzeliswa ukuya ngaphantsi kwe-1.0 yesibini. Iiwelder ze-MFDC zixhasa iiprothokholi zemizi-mveliso eziqhelekileyo ezifana ne-Profinet kunye ne-EtherNet/IP, ivumela i-millisecond{2}}inqanaba lonxibelelwano kunye neerobhothi ezivela kwi-FANUC, i-KUKA, kunye nezinye. Yakhelwe-kwi-Adaptive Control function ibuyekeza ngokuzenzekela ngokwangoku ngokusekwe kwiiyantlukwano zesikhewu samaphepha, iqinisekisa ukungaguquguquki kweweld nakumazinga aphezulu emveliso.
Ukuveliswa kweFlexible kunye neDigital Traceability: Intlanganiso ye-IATF 16949 yoPhicotho-zincwadi
Iiplanti zeemoto zala maxesha ziqhele ukusebenzisa{0}}imodeli yemigca yemveliso exubeneyo, efuna ubhetyebhetye oluphezulu kunye nolawulo oluphezulu lwedatha kwisixhobo sokuwelda.
1. Ukutshintshela iParameter ngokukhawuleza nge-64 Presets
Izixhobo ze-MFDC ze-Haifei zixhasa ukugcinwa kunye nokukhumbula ukuya kuthi ga kwiiseti ze-64 zeeparamitha ze-welding. Xa umgca utshintsha ukusuka kwi-sedan ukuya kwimodeli ye-SUV, i-PLC inokubangela utshintsho ngekhowudi enye, ivumela izixhobo ukuba zizalise utshintsho lweparameter ngaphantsi kwemizuzu eyi-10, ukukhusela ngokufanelekileyo iziphene zebhetshi ezibangelwa iimpazamo zeparameter manual.
2. 100% Ukulandelelwa kweDatha yeNkqubo yeWeld
Ukuthobela i-IATF 16949 kunye neemfuno zophicotho lwe-OEM, inkqubo ye-MFDC ngokuqhubekayo iqokelela idatha yangoku, umbane, uxinzelelo, kunye nokufuduswa kwe-electrode. Itheyibhile engezantsi ichaza iimetrics ezingundoqo ezibekwe esweni yinkqubo ekrelekrele:
| I-Metric ebekwe esweni | Umsebenzi/Impembelelo | Iikhrayitheriya zoKwamkeleka koMgangatho |
| I-Welding yangoku | Imisela igalelo lobushushu kunye nobungakanani be-nugget | Ukuguquguquka kulawulwa ngaphakathi ±2% |
| I-Electrode Force (Uxinzelelo) | Ichaphazela ukuchasana noqhagamshelwano kunye nokugxothwa | Iqinisekisa ukwakheka kwe-nugget efanelekileyo ngaphandle kokugxothwa ngokugqithisileyo |
| I-Electrode Displacement | Ibonakalisa ukukhula kwe-nugget kunye nokuwa | Isetyenziselwa ukubona ngokuzenzekelayo iiweldi ezibandayo okanye ngaphezulu{0}}ukuwelda |
| Ukuchasa okunamandla | Isalathisi esibanzi somgangatho wenkqubo | Isetyenziselwa uLawulo lweNkqubo yeNkxaso-manani (i-SPC) itshathi yohlalutyo |
Ingcebiso eSebenzayo: Ungayikhetha njani i-MFDC Spot Welder kwiiNdlela zeZithuthi
- Vavanya ukuGuqulwa rhoqo:Beka phambili iimodeli nge-1000Hz okanye ngaphezulu. Iifrikhwensi eziphezulu zivumela ulawulo lwangoku olucokisekileyo kwaye zinikeze ukusebenza kakuhle kwamandla (malunga ne-30% ngokufanelekileyo kune-welders ze-AC).
- Qinisekisa Ulawulo Oluziqhelanisayo:Kwizicelo ze-BIW ezinezikhewu ezilungelelanisiweyo{0}phezulu, i-Adaptive Control function ibalulekile ekuthinteleni isitshizi kunye ne-welds ezibandayo.
- Vavanya iSakhono seNkonzo yeNdawo:Ixesha lokuphumla kumgca wemoto libiza kakhulu. Ukukhetha umthengisi ofana neHaifei, enamaziko amaninzi eenkonzo zobugcisa kwaye iqinisekisa i-24-yeyure{3}}kwimpendulo yesayithi, ibalulekile kuzinzo lwexesha elide lokusebenza.
Ukuqukumbela
Ukutshintshela kwi-MFDC welding spot kungaphezulu nje kokuphuculwa kwezixhobo; linyathelo elibalulekileyo kwinguqu yoshishino lweemoto ukuya kwimveliso yobukrelekrele nedijithali. Ngolawulo oluchanekileyo lwamandla kunye nokulandelelwa kwedatha ebanzi, ubuchwepheshe be-MFDC bukhusela umgangatho kunye nokhuseleko lwesithuthi ngasinye endleleni.
